Key Parameters

Substitute Part Grouping Explanation

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

• Resistance value: 6.49 kOhms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Automotive qualification: AEC-Q200
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm)
• Height: 0.028" (0.70mm) maximum

All identified substitute parts match these parameters. Variations in product status, RoHS compliance, and manufacturer series do not affect electrical or mechanical interchangeability for this application.

Parameter Comparison

Engineering Selection Recommendations

CRCW20106K49FKEF (Vishay Dale) is the primary substitute for RMCF2010FT6K49. Both parts are active in production, ROHS3 compliant, and fully qualified for automotive applications. This part provides equivalent electrical performance and mechanical compatibility with no design modifications required.

ERJ-12SF6491U (Panasonic Electronic Components) is electrically and mechanically equivalent but carries two compliance considerations: the part is marked "Not For New Designs" and is RoHS non-compliant. This part is suitable for legacy system maintenance and field replacement only, not for new product development.

Frequently Asked Questions (FAQ)

Q: Can CRCW20106K49FKEF be used as a direct replacement for RMCF2010FT6K49?

A: Yes. Both parts share identical electrical specifications (6.49 kOhms ±1%), power rating (0.75W), package dimensions (2010/5025 Metric), and automotive AEC-Q200 qualification. No circuit modifications are required.

Q: What is the difference between the three parts?

A: All three parts are electrically and mechanically identical. The differences are manufacturer identity, product lifecycle status, and regulatory compliance. RMCF2010FT6K49 and CRCW20106K49FKEF are both active production parts with ROHS3 compliance. ERJ-12SF6491U is marked "Not For New Designs" and is RoHS non-compliant.

Q: Can ERJ-12SF6491U be used in new automotive designs?

A: ERJ-12SF6491U is electrically and mechanically compatible but is not recommended for new designs due to its "Not For New Designs" status and RoHS non-compliance. Use RMCF2010FT6K49 or CRCW20106K49FKEF for new product development.

Q: Are all three parts suitable for the -55°C to 155°C operating temperature range?

A: Yes. All three parts are rated for -55°C to 155°C operation with ±100ppm/°C temperature coefficient.

Q: Do these parts require different PCB footprints?

A: No. All three parts use the 2010 (5025 Metric) package with identical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) and 0.028" (0.70mm) maximum seated height. A single PCB footprint accommodates all three parts.

Q: What is the moisture sensitivity level for these parts?

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