Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RMCS2512FT2K40 are qualified based on the following criteria:

• Resistance value: 2.4 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All identified substitutes meet these core electrical and mechanical parameters. Variations in dimensional tolerances and feature sets (such as automotive qualification or moisture resistance) do not affect functional interchangeability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the RMCS2512FT2K40. Selection among these alternatives should be based on:

• Availability and lead time requirements
• Specific application certifications: RMCF2512FT2K40 and CRCW25122K40FKEG carry AEC-Q200 automotive qualification; RC2512FK-072K4L features moisture-resistant construction
• Packaging format preference: RMCF2512FT2K40 and RC2512FK-072K4L are supplied in Tape & Reel; CRCW25122K40FKEG is available in Cut Tape & Digi-Reel
• Supplier inventory and cost considerations

All parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8533.21.0030).

Frequently Asked Questions (FAQ)

Q: Can RMCF2512FT2K40 be used as a direct replacement for RMCS2512FT2K40?

A: Yes. Both parts share identical electrical specifications (2.4 kOhms, ±1%, 1W, ±100ppm/°C, -55°C ~ 155°C). The RMCF variant includes AEC-Q200 automotive qualification and operates within the same package footprint. Dimensional variations (RMCF: 6.30mm x 3.20mm vs. RMCS: 6.35mm x 3.10mm) are within standard PCB tolerance ranges for 2512 package placement.

Q: What is the difference between CRCW25122K40FKEG and the Stackpole alternatives?

A: CRCW25122K40FKEG is manufactured by Vishay Dale and meets identical electrical requirements. It carries AEC-Q200 automotive certification and is supplied in Cut Tape & Digi-Reel packaging. Dimensional specifications (6.30mm x 3.15mm) align with standard 2512 package tolerances.

Q: Is RC2512FK-072K4L suitable for moisture-sensitive applications?

A: RC2512FK-072K4L features moisture-resistant construction and maintains MSL 1 (Unlimited) rating, identical to other listed substitutes. The moisture-resistant feature provides additional protection in high-humidity environments without affecting electrical performance or package compatibility.

Q: Are there packaging considerations when switching between these parts?

A: All parts use the 2512 (6432 Metric) package with compatible footprints. Dimensional tolerances are within standard PCB design margins. Packaging format differs: Stackpole and YAGEO parts are supplied in Tape & Reel; Vishay Dale CRCW25122K40FKEG is available in Cut Tape & Digi-Reel. Verify supplier packaging availability for your procurement requirements.

Q: Do all substitutes meet the same compliance standards?

A: Yes. All listed parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 with MSL 1 rating. Compliance documentation is equivalent across all alternatives.
