Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F6493CS is determined by strict equivalence across the following parameters:

Electrical Specifications: Resistance value (649 kOhms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must be identical.

Package Compatibility: All substitute parts must use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm).

Environmental Ratings: Operating temperature range (-55°C ~ 155°C), Moisture Sensitivity Level (MSL 1), RoHS3 compliance, and REACH unaffected status must be maintained.

Composition: Thick film construction is required for all substitutes.

The following parts meet these criteria and are classified as direct or similar substitutes based on feature alignment.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical equivalence to the RC2012F6493CS. Selection among these alternatives is based on availability, supply chain considerations, and application-specific requirements.

RC0805FR-07649KL (YAGEO): Direct substitute with identical electrical specifications and moisture-resistant thick film construction. Seated height of 0.024" (0.60mm) is within acceptable tolerance for standard PCB layouts. ROHS3 compliant and REACH unaffected.

CRCW0805649KFKEA (Vishay Dale): Qualified substitute with AEC-Q200 automotive rating. Lowest seated height at 0.020" (0.50mm) provides additional clearance margin in space-constrained applications. ROHS3 compliant and REACH unaffected.

ERJ-6ENF6493V (Panasonic Electronic Components): Qualified substitute with AEC-Q200 automotive rating. Seated height of 0.028" (0.70mm) represents maximum height among substitutes. ROHS3 compliant and REACH unaffected.

RMCF0805FT649K (Stackpole Electronics Inc): Qualified substitute with AEC-Q200 automotive rating. Seated height of 0.026" (0.65mm) aligns closely with the original part specification. ROHS3 compliant and REACH unaffected.

All parts are Active in product status and maintain unlimited moisture sensitivity rating (MSL 1), ensuring long-term reliability in standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07649KL replace RC2012F6493CS in all applications?

A: Yes. RC0805FR-07649KL maintains identical electrical specifications (649 kOhms ±1%, 0.125W), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and package dimensions (0805 / 2012 Metric). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between moisture-resistant and automotive AEC-Q200 variants?

A: The RC2012F6493CS and RC0805FR-07649KL feature moisture-resistant thick film construction. The CRCW0805649KFKEA, ERJ-6ENF6493V, and RMCF0805FT649K include AEC-Q200 automotive qualification in addition to moisture resistance. AEC-Q200 qualification indicates compliance with automotive reliability and environmental stress testing standards. Both types are suitable for general industrial and consumer applications.

Q: Are there height restrictions when substituting these parts?

A: Seated height varies between 0.020" (0.50mm) and 0.028" (0.70mm) across substitutes. The original RC2012F6493CS specifies 0.026" (0.66mm). All variants remain within standard PCB assembly tolerances. Verify PCB layout clearance requirements for space-constrained designs.

Q: Do all substitutes maintain the same tolerance and temperature coefficient?

A: Yes. All identified substitutes maintain ±1% tolerance and ±100ppm/°C temperature coefficient, ensuring equivalent performance in precision circuit applications.

Q: Are these parts interchangeable on the PCB without design changes?

A: Yes. All substitutes use identical 0805 (2012 Metric) footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) with two terminations. Direct PCB footprint compatibility is confirmed.

Q: What compliance certifications apply to all substitutes?

A: All parts are ROHS3 compliant and REACH unaffected. Moisture Sensitivity Level is MSL 1 (unlimited) for all variants, indicating no special storage or handling requirements.
