A Yageo CC cross-reference for Brazil needs the thickness band as well as the five electrical fields. We opened six real Yageo CC numbers on Yageo’s own pages and matched them to Walsin’s MLCC export: 4 have a general-purpose twin on our Hong Kong shelf, and only 3 of those also print the same thickness band.
Venatech Limited, an authorised Walsin distributor in Hong Kong, holds the Walsin Technology (Walsin) MLCC export of 24,026 rows, 23,601 of them distinct part numbers. This post is for a purchasing or design engineer at a Brazilian electronics maker whose bill of materials names Yageo CC capacitors and who wants a second source that ships from Hong Kong in small lots. Every part number below is real. Every count is ours. The six Yageo numbers were each opened on Yageo’s own specsheet page on 23 October 2026.
What do Brazil’s component import figures say about demand for a Hong Kong MLCC source?
They say Brazil’s electronics sector buys components abroad at very large scale, and nothing about any single part. Abinee’s 2026 sector overview, which carries 2025 data, prints sector sales of 272.0 billion reais (48.7 billion US dollars), imports of electrical and electronic components of 23.5 billion US dollars, and a sector trade deficit of 40.6 billion US dollars. We read the page on 23 October 2026.
The page carries no publication date, so we cite it as the 2026 edition with 2025 figures. Abinee is the Brazilian electrical and electronics industry association, and its “components” category is its own grouping, not a customs heading.
Our view, labelled as ours: a Brazilian maker that imports capacitors against a board BOM has one working question, which is whether the part on the BOM has a second source that matches field by field. That is the question the rest of this post answers for one maker’s numbering scheme.
How do you read a Yageo CC part number?
As a string of fields, and the voltage is one character, not a number. We opened six CC numbers on Yageo’s pages and read the voltage character against Yageo’s printed rating each time: 6 is 10 V, 7 is 16 V, 8 is 25 V and 9 is 50 V. The size is the literal inch case, and the tolerance is one letter.
| Position | CC0805KKX5R8BB106 |
Reads as | Walsin counterpart |
|---|---|---|---|
| 1 | CC |
Yageo ceramic capacitor | Walsin has no prefix for a general-purpose part |
| 2 | 0805 |
EIA inch case 0805 | Size 0805 in the export |
| 3 | K |
Tolerance ±10% | Tolerance K in the Walsin number, +-10% in the export |
| 4 | K |
Packaging letter | Mismatch: the export’s Packing and SPQ columns are empty |
| 5 | X5R |
Dielectric | Dielectric X5R; Walsin writes X in the number |
| 6 | 8 |
25 V | Rated voltage 25 Vdc, 250 in the Walsin number |
| 7 | BB |
Two letters we did not confirm | Mismatch: no Walsin field |
| 8 | 106 |
10 µF | Capacitance 10 µF, 106 in the Walsin number |
The packaging letter was R on the 0402 and 0603 numbers we opened and K on the 0805 and 1206 numbers. The two letters before the capacitance code were BB on the X5R and X7R numbers and BN on the C0G number, so they carry something that varies by dielectric. We did not find their meaning on the pages we opened, so we do not state it.
Which Walsin parts match six verified Yageo CC numbers?
Each Yageo number has a general-purpose Walsin twin on five fields, and the twins differ on shelf status and thickness. We parsed all 24,026 rows and counted 59 Walsin part numbers on the same four fields (size, dielectric, capacitance, rated voltage) across the six cells, from 3 in the 10 µF cell to 25 in the 10 pF cell.
| Yageo CC number | Fields | Walsin rows on size, dielectric, capacitance, voltage | General-purpose Walsin twin | On shelf 23 September 2026 | Match / mismatch |
|---|---|---|---|---|---|
CC0402KRX7R7BB104 |
0402, X7R, 100 nF, 16 V, ±10% | 11 | 0402B104K160 |
Yes | Match on five fields; mismatch on packaging letter |
CC0603KRX5R6BB105 |
0603, X5R, 1 µF, 10 V, ±10% | 5 | 0603X105K100 |
No | Match on five fields; mismatch on shelf status |
CC0805KKX5R8BB106 |
0805, X5R, 10 µF, 25 V, ±10% | 3 | 0805X106K250 |
Yes | Match on five fields; mismatch on packaging letter |
CC1206KKX7R9BB105 |
1206, X7R, 1 µF, 50 V, ±10% | 10 | 1206B105K500 |
Yes | Match on five fields; mismatch on thickness band |
CC0402JRNPO9BN100 |
0402, C0G, 10 pF, 50 V, ±5% | 25 | 0402N100J500 |
Yes | Match on five fields; mismatch on packaging letter |
CC0805KKX7R8BB225 |
0805, X7R, 2.2 µF, 25 V, ±10% | 5 | 0805B225K250 |
No | Match on five fields; mismatch on shelf status |
Walsin writes 1 µF as 1000nF and 2.2 µF as 2200nF in the export, while 10 µF is 10uF, which is why a text search for 1uF misses the 0603 and 1206 cells. We converted every capacitance spelling to picofarads before counting. The 0805 10 µF 25 V cell is the thinnest, with 3 parts.
The 10 pF cell is the crowded one: 25 parts in six series, from general purpose to microwave. Most are not twins for a general-purpose line. Only the four with a general-purpose prefix, and only one at ±5%, are the plain cross.
Why do only 3 of 6 twins match on both shelf and thickness band?
Because shelf status and thickness band are independent fields, and they overlap on 3 numbers. We read the thickness Yageo prints on each page and compared it with the T column of the Walsin twin: 4 bands are identical in form and 2 are not, and the 2 that differ overlap with the 2 off-shelf twins on only one number.
| Yageo CC number | Yageo thickness | Walsin twin and its T column |
On shelf | Match / mismatch |
|---|---|---|---|---|
CC0402KRX7R7BB104 |
0.5 ± 0.05 mm | 0402B104K160, 0.50±0.05 |
Yes | Match on thickness band; no mismatch found |
CC0603KRX5R6BB105 |
0.8 ± 0.1 mm | 0603X105K100, 0.80+0.15/-0.10 |

1.25 ± 0.2 mm | 0805B225K250, 1.25±0.20 |

We have not seen this counted anywhere: only 3 of the 6 numbers (the 0402 X7R, the 0805 X5R and the 0402 C0G) reach the shelf with an identical thickness band. The 1206 twin is stocked but prints a plus-side band 0.1 mm wider than Yageo’s. The 0603 X5R twin has the same band issue and is not stocked. The 0805 2.2 µF twin matches the band and is not stocked.
Does a wider plus side matter? That depends on your placement height and stencil, and only you can say. Walsin’s T column is the export’s value, and the datasheet for the exact part decides. Our post on how to cross-reference an MLCC sets out the thickness check, and crossing an 0603 X7R line from Murata to Walsin shows the same band mismatch for another maker.
What do we hold in stock, and what does our paperwork leave out?
We hold 4 of the 6 twins, and our paperwork has no packaging match. Our stock list as at 23 September 2026 holds 1,125 part numbers, and 0402B104K160, 0805X106K250, 1206B105K500 and 0402N100J500 are among them; the export’s Packing and SPQ columns are empty on all 24,026 rows, so we cannot cross Yageo’s packaging letter from the export.
We hold 28 Walsin datasheets, 451 pages, and 26 of them cover MLCC series. We can send the one covering your part number on request. The stock list is a dated snapshot. It is not live. The ready stock page shows what is held in Hong Kong from that snapshot, and we quote part-number counts, never piece counts. We make no price, lead-time or stock promise in this post.
Brazilian import, tax and incentive rules are for your compliance team. We give no legal or customs advice.
How can Venatech help a Brazilian electronics maker?
By crossing the Yageo CC number you already use, stating every difference, and telling you what is missing. Venatech Limited is an authorised Walsin distributor in Hong Kong. Walsin is our only authorised line, and the other lines we supply are Stackpole and Viking.
- Cross-reference. Paste your Yageo, Murata, Samsung or TDK number into the free cross-reference tool, which decodes 18 manufacturers’ part numbers across 800,000+ crossable parts, and read each Walsin candidate with match and mismatch stated field by field.
- BOM check. Upload a board bill of materials to /bom/ and have each line checked against the same engine.
- Ready stock. The ready stock list is a Hong Kong snapshot dated 23 September 2026, never live-synced.
- Service. Hong Kong-based, small lots, cross-referencing help, and a quote requested through the site. Our address is Unit 207, 2/F, Sun Ling Plaza, 30 On Kui Street, Fanling, N.T., Hong Kong, telephone (852) 2628 4777.
A worked example from our own export: CC0805KKX5R8BB106, a 10 µF, 25 V, X5R, ±10%, 0805 part, maps to 0805X106K250, which is stocked and prints the same thickness band. A ±20% line maps to 0805X106M250, a factory order. Our MLCC range lists the families. Confirm against both datasheets and qualify in your own circuit.
The short version
Brazil’s 2025 component imports were 23.5 billion US dollars, per Abinee’s 2026 overview. Of six real Yageo CC numbers, 4 have a general-purpose Walsin twin on our shelf and only 3 also print the same thickness band. The packaging letter and two further letters have no Walsin field.
Send us the Yageo CC lines from one board and we will return the Walsin candidates with every difference stated. When your 1206 line prints a thickness band 0.1 mm wider on one side, does your stencil or your placement height notice?

How much did Brazil import in electrical and electronic components in 2025?
Abinee’s 2026 sector overview, which carries 2025 data, prints 23.5 billion US dollars of imports in electrical and electronic components. The same page prints sector sales of 272.0 billion reais and a sector trade deficit of 40.6 billion US dollars. The page is undated, and the grouping is Abinee’s own.
How is the voltage read in a Yageo CC part number?
It is a single character after the dielectric block. On the six numbers we opened, 6 was 10 V, 7 was 16 V, 8 was 25 V and 9 was 50 V, each checked against the rating Yageo prints on its page. Do not read it as a number of volts or as an exponent.
Does Walsin have a twin for CC0805KKX5R8BB106?
Yes on five fields. 0805X106K250 is 0805, X5R, 10 µF, 25 V and ±10%, and it is on our shelf as at 23 September 2026. Its export thickness reads 1.25±0.20 mm, the same form as Yageo’s printed 1.25 ± 0.2 mm. The packaging letter has no Walsin field.
Why are two of the six twins off your shelf?
They are 0603X105K100 and 0805B225K250. Both match on five fields and are factory orders, not held in the Hong Kong stock list as at 23 September 2026. Ask us for the Walsin datasheet and a quote for the exact part. We make no lead-time promise.
Can I swap a Yageo CC for the Walsin twin without testing?
No. We state differences, not equivalence. The twin matches on size, dielectric, capacitance, voltage and tolerance, and it may differ in thickness band, termination and DC bias curve. Confirm against both datasheets and qualify the part in your own circuit.
Do you advise on Brazilian import rules?
No. Brazilian import, tax and incentive rules are for your compliance team. We cross the part, state the differences and quote from Hong Kong in small lots through the site.
