Samsung MLCC Alternative for Vietnam Factories: 119 Walsin 0603 and 0805 X5R and X7R Parts From Walsin’s Authorised Distributor in Hong Kong

A Samsung MLCC alternative is the fastest fix when a Samsung-specified capacitor is hard to get from your usual channel in Vietnam. Our Hong Kong ready stock list as at 9 November 2026 carries 119 Walsin 0603 and 0805 X5R and X7R parts, and we source the Samsung original on request. Venatech is the authorised Walsin distributor in Hong Kong.

Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a buyer or design engineer at a supplier or EMS plant in Thai Nguyen, Bac Ninh or elsewhere in Vietnam whose BOM names Samsung MLCC. Walsin Technology (Walsin) is the line we are authorised for. We are not authorised for Samsung; through our supplier network in Hong Kong we source Samsung and most other passive-component brands on request, including urgent spot buys when a line is short of parts, while Walsin comes through our authorised channel. Nothing here says any Samsung part is short or constrained; only Samsung can tell you that. We counted the figures below on 13 November 2026 by matching our ready stock list as at 9 November 2026 (1,174 distinct Walsin part numbers) against our MLCC export, Venatech_MLCC_Upload_01.xlsx to Venatech_MLCC_Upload_08.xlsx.

How big is Samsung’s manufacturing base in Vietnam?

Samsung’s mobile phone manufacturing entities in Bac Ninh and Thai Nguyen had exported a cumulative 500 billion US dollars by the end of June 2026, the Vietnamese Government news portal reported on 28 August 2026. The portal put Samsung’s cumulative investment in Vietnam at 24 billion US dollars over 17 years since production began in April 2009, and reported the Prime Minister’s call for a higher proportion of locally sourced products and services.

Those are the portal’s figures, not ours. Seventeen years of phone production built a supplier base around Samsung’s plants. Where a supplier’s BOM follows the brands its customer’s engineers specified and one of those capacitors is late from the usual channel, the buyer has two routes: a cross the customer accepts, or the original part from another source.

Which Walsin 0603 and 0805 MLCC are on the Hong Kong ready stock list?

We counted 119 Walsin general-purpose X5R and X7R MLCC in 0603 and 0805 on our ready stock list as at 9 November 2026. In 0603 there are 50 X7R and 10 X5R parts; in 0805 there are 50 X7R and 9 X5R parts, reaching 22 uF in 0603 and 47 uF in 0805 in X5R.

Size and dielectric	Lines on the list	Capacitance span on the list	Voltage span on the list	Example part	Match / mismatch with a 10 uF, X5R, 10 V, 0603 brief
0603 X7R	50	180 pF to 2.2 uF	6.3 to 100 V	0603B105K160	Mismatch on value and dielectric
0603 X5R	10	1 uF to 22 uF	6.3 to 25 V	0603X106K100	Match
0805 X7R	50	180 pF to 10 uF	10 to 100 V	0805B106K100	Mismatch on size and dielectric
0805 X5R	9	2.2 uF to 47 uF	6.3 to 50 V	0805X106K250	Mismatch on size; higher voltage

The list also carries 61 C0G/NP0 parts in 0603 and 36 in 0805. We publish part numbers, not quantities: the ready stock list is a dated snapshot, not live-synced, and we confirm availability, date code and lead time on each quote.

Which Walsin part crosses a Samsung-specified 0603 or 0805 MLCC?

We checked nine briefs of the kind a Samsung-specified BOM carries, and eight return a Walsin part on the list. We work from the specification on your Samsung datasheet, not from the Samsung part number, because size, dielectric, value, tolerance and voltage decide the cross and thickness confirms it.

Brief from your Samsung datasheet	Walsin part on the list	Dielectric, tolerance, voltage (our export)	Match / mismatch	Your Samsung part
10 uF, X5R, 10 percent, 10 V, 0603	0603X106K100	X5R, 10 percent, 10 V	Match; check thickness
22 uF, X5R, 20 percent, 6.3 V, 0603	0603X226M6R3	X5R, 20 percent, 6.3 V	Match; check thickness
1 uF, X7R, 10 percent, 16 V, 0603	0603B105K160	X7R, 10 percent, 16 V	Match
100 nF, X7R, 10 percent, 50 V, 0603	0603B104K500	X7R, 10 percent, 50 V	Match
10 uF, X5R, 10 percent, 25 V, 0805	0805X106K250	X5R, 10 percent, 25 V	Match
10 uF, X7R, 10 percent, 10 V, 0805	0805B106K100	X7R, 10 percent, 10 V	Match
22 uF, X5R, 20 percent, 10 V, 0805	0805X226M100	X5R, 20 percent, 10 V	Match
47 uF, X5R, 20 percent, 6.3 V, 0805	0805X476M6R3	X5R, 20 percent, 6.3 V	Match; check DC bias
10 uF, X5R, 16 V, 0603	0805X106K160 (0805)	X5R, 10 percent, 16 V	Mismatch on size: request an 0603 quote through our authorised Walsin channel

Fill in your Samsung part in the last column. Our post on crossing Samsung MLCC families to Walsin explains the series-level view behind this table.

Should a Vietnam supplier cross a Samsung MLCC or source the original?

It depends on who owns the approval, and we quote both so the buyer can choose. If your customer’s approved vendor list names the Samsung part, ask us to source the original; if the customer allows a second source, a Walsin cross gives you a part through an authorised channel with Walsin’s own documentation.

• Source the original when the drawing, the AVL or a quality file names the Samsung part, or when the build ships before a cross could be approved.
• Cross to Walsin when the customer accepts a second source, or when you want one in place before the next shortage.
• Do both when the line is down now: the sourced original keeps the line running while the cross goes through approval.

For the original we state date code and origin on the quote. Our post on when not to cross lists the cases where you keep the original part.

What do bulk X5R parts need checked before a cross?

Three fields matter most for 10 uF to 47 uF X5R parts in 0603 and 0805: thickness, DC bias and temperature range. Two parts with the same value, size and voltage can differ in height and in how much capacitance they keep at working voltage, so read both on Walsin’s datasheet before you sign off a cross.

Thickness affects stencil, nozzle and any shield can above the part. DC bias decides how much of a 22 uF part is left at 5 V; our post on MLCC DC bias and voltage derating shows how to read the curve. X5R is rated to 85 C, X7R to 125 C: a cross from X7R to X5R needs the design owner’s agreement.

How Venatech helps: how does a Vietnam buyer cross or source a Samsung MLCC?

How Venatech helps: paste the Samsung part, get the Walsin cross with every field marked, and ask for a quote on the original in the same request. Venatech is the authorised Walsin distributor in Hong Kong; VenaMatch decodes 18 manufacturers’ part numbers and crosses 800,000+ parts to Walsin, marking each field as match or mismatch.

Use the cross-reference tool, upload a BOM, or send the request-a-quote form on the site. The MLCC range lists every Walsin family. We serve from Hong Kong in small lots and quote fast. We give no price, lead-time, stock or delivery guarantee, and no customs advice: confirm import paperwork with your compliance team.

The short version

• Samsung’s phone entities in Bac Ninh and Thai Nguyen reached 500 billion US dollars of cumulative exports by June 2026, per the Government news portal on 28 August 2026.
• Our Hong Kong ready stock list as at 9 November 2026 carries 119 Walsin X5R and X7R MLCC in 0603 and 0805.
• Eight of nine Samsung-style briefs return a Walsin part on the list.
• When the AVL names the Samsung part, we source the original on request; Walsin is the line we are authorised for.

Paste the Samsung MLCC that is holding your build into the cross-reference tool. Does your customer accept a second source?
