Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCF2512FT357R is determined by the following critical parameters:

• Resistance value: 357 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package footprint: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match or better required)
• Automotive Compliance: AEC-Q200 (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The CRCW2512357RFKEGHP from Vishay Dale qualifies as a substitute because it maintains all critical electrical parameters and package specifications. The power rating increase from 1W to 1.5W represents an upgrade that does not compromise compatibility, as the component occupies the same physical footprint and maintains identical resistance, tolerance, and temperature characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the RMCF2512FT357R and CRCW2512357RFKEGHP are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on availability and supply chain requirements. The CRCW2512357RFKEGHP offers increased power dissipation capability (1.5W versus 1W) while maintaining identical electrical specifications and package dimensions, making it suitable for applications requiring additional thermal margin. Both components are qualified for the full -55°C to 155°C operating temperature range and maintain ±100ppm/°C temperature coefficient stability.

Frequently Asked Questions (FAQ)

Q: Can the CRCW2512357RFKEGHP replace the RMCF2512FT357R in existing designs?

A: Yes. Both components share identical resistance (357 Ohms), tolerance (±1%), package footprint (2512), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The increased power rating of the substitute (1.5W versus 1W) does not create compatibility issues.

Q: Are there dimensional differences between these parts?

A: Both components use the 2512 (6432 Metric) package with maximum seated height of 0.028" (0.70mm). Length is 0.248" (6.30mm) for both. Width differs slightly: 0.126" (3.20mm) for the RMCF2512FT357R and 0.124" (3.15mm) for the CRCW2512357RFKEGHP. These variations fall within standard 2512 package tolerances and do not affect PCB footprint compatibility.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the RMCF2512FT357R and CRCW2512357RFKEGHP carry AEC-Q200 automotive qualification and are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the substitution basis for these parts?

A: Substitution is based on matching resistance value (357 Ohms), tolerance (±1%), package format (2512), composition (Thick Film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive compliance (AEC-Q200). The CRCW2512357RFKEGHP qualifies as a direct substitute with an upgraded power rating.
