Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCF2512FT511K is determined by strict equivalence across the following parameters:

• Resistance value: 511 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package designation: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The CRCW2512511KFKEG from Vishay Dale meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the RMCF2512FT511K and CRCW2512511KFKEG are active production parts with identical electrical specifications and automotive AEC-Q200 qualification. Both parts maintain ROHS3 compliance and MSL 1 rating. The physical dimensions are equivalent within standard manufacturing tolerances, with width variance of 0.002" (0.05mm) that does not affect PCB footprint compatibility. Selection between these parts may be based on availability, packaging format preference (Tape & Reel versus Cut Tape & Digi-Reel), or supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512511KFKEG be used as a direct replacement for RMCF2512FT511K?

A: Yes. Both parts share identical electrical specifications (511 kOhms ±1%, 1W), the same 2512 package, equivalent physical dimensions, and AEC-Q200 automotive qualification. They are electrically and mechanically interchangeable.

Q: Are there any dimensional differences between these parts?

A: The width dimension differs by 0.002" (0.05mm): RMCF2512FT511K is 0.126" (3.20mm) wide, while CRCW2512511KFKEG is 0.124" (3.15mm) wide. This variance is within standard PCB footprint tolerances and does not affect compatibility.

Q: Do both parts meet automotive standards?

A: Yes. Both the RMCF2512FT511K and CRCW2512511KFKEG are AEC-Q200 qualified for automotive applications and operate across the same temperature range of -55°C to 155°C.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is supplied on continuous tape for automated pick-and-place assembly. Cut Tape & Digi-Reel packaging provides smaller quantities on cut tape segments. Both formats contain identical components; the difference is in supply format and quantity per reel.

Q: Are both parts RoHS compliant?

A: Yes. Both RMCF2512FT511K and CRCW2512511KFKEG are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level).
