Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2211CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.21 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package format: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

The identified substitute parts meet all mandatory parameters. Differences in packaging format (Tape & Reel versus bulk) and additional certifications (AEC-Q200 automotive qualification) do not affect electrical or thermal equivalence but may influence procurement and application suitability.

Parameter Comparison

Engineering Selection Recommendations

RC6432F2211CS (Samsung Electro-Mechanics): Select this part for applications requiring the original Samsung specification. The part is Active and maintains the lowest seated height at 0.026" (0.66mm), which may be advantageous in space-constrained designs. Moisture-resistant construction is specified.

CRCW25122K21FKEG (Vishay Dale): This substitute is suitable for designs requiring automotive-grade components with AEC-Q200 qualification. The part is available in Tape & Reel packaging with 5833 units in stock, providing high availability. Seated height is 0.028" (0.70mm), and width is 0.124" (3.15mm), representing minimal dimensional variation.

RMCF2512FT2K21 (Stackpole Electronics Inc): This substitute offers automotive AEC-Q200 qualification and is available in Tape & Reel format with 2936 units in stock. Dimensional specifications match the original part exactly (0.248" L x 0.126" W), with seated height at 0.028" (0.70mm).

All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8533.21.0030.

Frequently Asked Questions (FAQ)

Q: Can CRCW25122K21FKEG replace RC6432F2211CS in non-automotive applications?

A: Yes. Both parts share identical electrical specifications (2.21 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C). The AEC-Q200 automotive certification on the Vishay part does not restrict its use in general-purpose applications. Dimensional differences are minimal (width 3.15mm vs 3.20mm, height 0.70mm vs 0.66mm).

Q: What is the significance of the height difference between the Samsung part (0.66mm) and the substitute parts (0.70mm)?

A: The 0.04mm height difference is within typical PCB assembly tolerances. For applications with strict height constraints, the RC6432F2211CS should be retained. For most standard applications, this variation is not functionally significant.

Q: Are the substitute parts available in the same packaging as the original?

A: The RC6432F2211CS is supplied in standard packaging. CRCW25122K21FKEG and RMCF2512FT2K21 are both available in Tape & Reel (TR) format, which is standard for high-volume production. Bulk or alternative packaging may require direct manufacturer inquiry.

Q: Do all three parts meet the same moisture sensitivity requirements?

A: Yes. All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, provided PCB layout accommodates the maximum seated height of 0.028" (0.70mm). The 2512 package footprint is identical across all three parts, and all meet the same electrical and thermal specifications.
