Substitute Part Grouping Explanation

Substitution eligibility for the RMCF1210FT28R7 is determined by strict equivalence across the following parameters:

• Resistance value: 28.7 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package: 1210 (3225 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

All identified substitute parts meet these criteria. Physical dimensions (length, width, height) and termination count remain consistent across all equivalents. Packaging format (Tape & Reel) is uniform across the product group.

Parameter Comparison

Engineering Selection Recommendations

CRCW121028R7FKEA (Vishay Dale) is the primary substitute for new designs and ongoing production. This part maintains full electrical and mechanical equivalence with the RMCF1210FT28R7, carries Active product status, and meets all automotive and compliance requirements. The seated height is 0.024" (0.60mm) compared to 0.028" (0.70mm) for the main part, which may provide marginal benefits in space-constrained applications without affecting electrical performance.

ERJ-14NF28R7U (Panasonic) is electrically and mechanically equivalent but carries a "Not For New Designs" product status. This part is suitable for legacy system support, field replacements, or applications where existing inventory must be maintained. The seated height matches the RMCF1210FT28R7 at 0.028" (0.70mm).

Frequently Asked Questions (FAQ)

Q: Can CRCW121028R7FKEA be used as a direct replacement for RMCF1210FT28R7 in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified, share identical electrical specifications (28.7 Ohms ±1%, 0.5W, ±100ppm/°C), operate across -55°C to 155°C, and use the 1210 (3225 Metric) package. The 0.004" (0.10mm) difference in seated height does not affect circuit compatibility.

Q: Why is ERJ-14NF28R7U marked "Not For New Designs"?

A: This designation reflects the manufacturer's product lifecycle status. The part remains electrically and mechanically equivalent and is available in inventory. It is suitable for replacement applications and legacy system support but should not be selected for new product development.

Q: Are all three parts interchangeable on the same PCB?

A: Yes. All three parts share identical footprint requirements (1210 package, 0.126" L x 0.098" W), termination count (2), and electrical characteristics. PCB layout and assembly processes require no modification when substituting between these parts.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. All meet AEC-Q200 automotive qualification.

Q: Does the 0.004" height difference between CRCW121028R7FKEA and the other parts affect clearance?

A: The CRCW121028R7FKEA seated height of 0.024" (0.60mm) is lower than the RMCF1210FT28R7 and ERJ-14NF28R7U at 0.028" (0.70mm). This difference is negligible for standard PCB assembly and does not create clearance issues in typical automotive applications. Verify clearance only if the design includes height-critical constraints.
