Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F28R7CS are qualified based on the following critical parameters that determine functional equivalence:

Mandatory Matching Parameters:

• Resistance value: 28.7 Ohms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Allowable Variation:

• Power Rating: Substitute parts rated at 0.75W (3/4W) are acceptable as they exceed the 0.667W requirement of the main part, providing enhanced thermal margin without affecting electrical performance in circuits designed for the original specification.

Both identified substitute parts meet all mandatory parameters and provide equivalent electrical and mechanical compatibility with the RC5025F28R7CS.

Parameter Comparison

Engineering Selection Recommendations

RC5025F28R7CS (Samsung Electro-Mechanics) - Primary Part

Use this part for standard applications where Active product status and general industrial specifications are sufficient. This component is currently in active production with established supply chain availability.

CRCW201028R7FKEF (Vishay Dale) - Preferred Substitute

This part is the recommended substitute for new designs and ongoing production. It maintains Active product status, provides AEC-Q200 automotive qualification, and offers increased power rating (0.75W vs. 0.667W) for enhanced thermal performance. All electrical and mechanical parameters are equivalent to the main part.

ERJ-12SF28R7U (Panasonic Electronic Components) - Legacy Substitute

This part carries "Not For New Designs" product status and should be used only for replacement or maintenance of existing assemblies. While electrically and mechanically equivalent, and AEC-Q200 qualified, the discontinued design status makes it unsuitable for new product development. Use only when maintaining compatibility with legacy systems.

Frequently Asked Questions (FAQ)

Q: Can CRCW201028R7FKEF be used as a direct replacement for RC5025F28R7CS?

A: Yes. Both parts share identical resistance (28.7 Ohms), tolerance (±1%), package (2010/5025 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and moisture sensitivity level (1). The CRCW201028R7FKEF provides higher power rating (0.75W vs. 0.667W), which is compatible with circuits designed for the original part.

Q: What is the difference between the 0.667W and 0.75W power ratings?

A: The 0.75W rating on substitute parts exceeds the 0.667W specification of the main part. This higher rating provides additional thermal margin and does not affect electrical performance in circuits designed for the original 0.667W component. The higher rating ensures the substitute part operates within safe thermal limits under identical load conditions.

Q: Why is ERJ-12SF28R7U marked "Not For New Designs"?

A: This designation indicates the part is in end-of-life status and no longer recommended for new product development. While the part remains electrically and mechanically equivalent, Panasonic has discontinued active development and promotion of this product line. Use this part only for replacement in existing systems to maintain compatibility.

Q: Are all three parts RoHS3 compliant?

A: Yes. RC5025F28R7CS, CRCW201028R7FKEF, and ERJ-12SF28R7U are all ROHS3 Compliant, meeting environmental and regulatory requirements for lead-free manufacturing and restricted substance limitations.

Q: What is the significance of AEC-Q200 qualification on the substitute parts?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions. Both CRCW201028R7FKEF and ERJ-12SF28R7U carry this certification, indicating they meet stringent automotive reliability and performance standards. This qualification is not specified for the RC5025F28R7CS but does not prevent its use in automotive applications.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All three parts share identical package dimensions (2010/5025 Metric: 0.197" L x 0.098" W / 5.00mm x 2.50mm) and two terminations. They are mechanically and electrically interchangeable in PCB layouts designed for the 2010 package footprint. Height variation (0.66mm to 0.70mm) is negligible for standard assembly processes.
