A Samsung MLCC cross reference is run at series and family level, not part number to
part number. Case size, dielectric, capacitance, tolerance and rated voltage narrow the
field; thickness, its tolerance band and series identity decide the candidate. Venatech
holds all 24,025 real parts across Walsin Technology (Walsin)’s 16 MLCC series. We hold no
Samsung lifecycle data, so confirm availability with Samsung directly.
Venatech Limited, an authorised Walsin distributor in Hong Kong, writes this from Walsin’s
own MLCC parametric export — 24,025 real rows across 16 series — and from the series
datasheets linked below. Every part number in this post exists in that export. Nothing here
describes a Samsung part number, and nothing states or implies that any Samsung series is
discontinued, obsolete, end-of-life or constrained; we hold no Samsung affected-part list and
cannot make that claim.
What does a Samsung MLCC cross reference actually produce?
A table, not a verdict. Five fields come off the Samsung datasheet you already hold: case
size, dielectric, capacitance, tolerance, rated voltage. Those five narrow Walsin’s catalogue
to a short list, never to one part automatically, because several Walsin series can share
identical values on all five.
What decides the actual candidate is the four fields a five-field match skips: thickness and
its tolerance band, termination type, AEC-Q200 status if your end application needs it, and
the CT packaging suffix that makes a catalogue code orderable. A cross that stops at the
five easy fields hands you a shortlist and calls it an answer.
Which Walsin MLCC series can hold a Samsung CL-series specification?
Sixteen series return parts in Walsin’s own export, and the one you land on depends on which
constraint actually matters to your board — not just the electrical values.

| Feed Thru 3-termination MLCC (FT) | 8 | 0402, 0805 | X5R, X7R | 4–50 Vdc |
For a commodity bypass or decoupling value — the ground a Samsung CL series most often
covers — General Purpose is the first shelf to check, with Low Profile (TT) and the two
soft-termination series (SH, SG) as the candidates when board height or flex is the actual
constraint. Figures measured from Walsin’s parametric export, September 2026.
Does a Walsin part number reliably resolve to one row in Walsin’s own export?
No, not always, and this is worth checking before you quote a thickness figure to anyone.
Walsin’s own combined MLCC export — the same 24,025-row file this post is written from —
contains 824 rows that resolve to only 399 distinct part numbers. The same catalogue code is
printed twice.
Unique to Venatech’s data. 399 distinct Walsin MLCC part numbers appear twice in
Walsin’s own single combined export (824 rows total), spread across nine series and led by
Middle to High Voltage Caps (208 part numbers) and General Purpose Caps (132). This builds
on Venatech’s own published finding that 381 of 23,601 distinct MLCC part numbers carry two
different thickness figures: here is where those 381 actually sit, plus the 18 that do not
differ on thickness at all. Of those 18, none is a byte-for-byte duplicate row — each pair
differs by something else instead. One pair,0603B102K500, has full L, W and T dimensions
on one row and no dimensions at all on the other. Several more carry a note reading
“Customized product. Please contact WTC local representative.” on one row of the pair and
nothing on the other. A part number alone, read from a single row, is not a safe source for
a dimension — you have to check whether that part number appears more than once first.
That is a defect in Walsin’s own export, not a criticism of Walsin’s parts. It means a script
that joins on part number and takes the first match can silently pick the wrong thickness,
the wrong tolerance band, or a row with no dimensions published at all.
What does a worked example look like at 1206, X5R, 10 µF, 25 V?
Seven real parts across three series, and one of the seven is itself a duplicate of the kind
described above.

Two things stand out. First, 1206X106K250 is one of the 399 duplicate part numbers above:
Walsin’s own export lists it twice at the same ±10% tolerance with two different thickness
tolerance bands, ±0.20 mm and +0.30/−0.10 mm. Second, the Low Profile TT candidate is barely
half the thickness of every other part on the line — 0.85 mm nominal against 1.60 mm — which
is the whole reason the TT series exists. If your board has a height budget under 1.2 mm at
this case size, TT is the only one of the seven that fits; if it does not, TT is irrelevant
and the choice is between tolerance grades on the other six.
Fill in your Samsung part’s figures in the blank column and mark each row match or mismatch
yourself. Neither this table nor this post approves a cross.
How do I check thickness when the series table does not show it?
Per part, not per case size, and from the datasheet dimension table rather than the headline
spec. The case size code fixes length and width; it does not fix thickness, and as the table
above shows, it does not even guarantee the thickness is recorded once per part number. Pull
the dimension line for the exact part number you intend to order and read both the nominal
and the tolerance band, not the nominal alone.
This is also where soft-termination parts differ structurally from hard-termination parts at
the same case size. SH and SG carry a wider dimensional tolerance band than General Purpose
or Low Profile at the same nominal size, because the compliant termination layer adds
material. A worst-case height budget has to use the worst-case figure, not the nominal.
How do I find out whether my Samsung part is still available?
Ask Samsung, or ask your Samsung distributor, in writing, for the exact part number on your
BOM. That is the only authoritative source for lifecycle status. We hold no such list, so
nothing here states that any Samsung part is discontinued, obsolete, end-of-life or
constrained; only Samsung can tell you that.
We will run the Walsin side of the comparison in parallel, with every match and mismatch
marked, so a qualified candidate is ready whether or not you decide you need one. The two
answers come from two different, non-overlapping sources: your incumbent manufacturer owns
the lifecycle truth, and we own the catalogue truth on the Walsin side.
The short version
Work at series level, not part number to part number. Pick the Walsin series the constraint
actually forces — General Purpose for the common case, Low Profile or soft-termination SH/SG
when height or board flex is the real driver — then check thickness per part number, because
Walsin’s own export is not guaranteed to publish it once. Confirm status with Samsung and
qualify the candidate yourself before release.
Send your Samsung MLCC specification and we will return the Walsin candidates at series
level, every mismatch marked, with a column left for your part.
Frequently asked questions
Can Venatech give me one Walsin part number to replace a Samsung MLCC?
Not as a single number with no table behind it. We return a field-by-field table — case size, dielectric, capacitance, tolerance, voltage, thickness and its tolerance band — with matches and mismatches marked, so the engineer who owns the circuit makes the final call.
Is a specific Samsung MLCC series discontinued?
We hold no such list, so we cannot tell you. There is no Samsung lifecycle data, affected-part list or allocation information on file here. Ask Samsung or your Samsung distributor in writing for the status of the exact part number on your BOM.
Why does the same Walsin part number appear twice in the export with different thickness figures?
We do not know the cause, only the measurement: 399 of Walsin’s distinct MLCC part numbers appear twice in the combined export, and 381 of those pairs disagree on thickness. Treat any single-row thickness lookup as unconfirmed until you check whether the part number repeats.
Which Walsin series is thinnest at a given case size?
Low Profile (TT) is built for that. At 1206, TT’s nominal thickness is 0.85 mm against 1.60 mm for General Purpose, Soft Termination SH and the other series at the same case size and value. TT’s case-size and dielectric coverage is narrower than General Purpose, so check availability at your exact value first.
Do soft-termination parts carry a wider thickness tolerance than standard parts?
Yes. At 1206 X5R 10 µF 25 V, the SH soft-termination part is toleranced ±0.50 mm against +0.30/−0.10 mm or ±0.20 mm for the General Purpose candidates. The worst-case body is larger even though the nominal size code is identical.
What do you need from me to start a Samsung-to-Walsin cross?
Case size, dielectric, capacitance, tolerance, rated voltage, your height budget, and whether AEC-Q200 or soft termination is required. If you only have a part number, send it and we will work back to the published specification.
How do you handle a specification Walsin does not carry?
We say so. Several Samsung dielectric or case-size combinations sit outside what Walsin publishes, and the honest answer is that the line returns nothing rather than a near-miss presented as a match.
