Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F4222CS are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 42.2 kOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100 ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts rated at 0.75W (3/4W) or higher are acceptable, as they provide equal or greater power dissipation capability within the same package footprint.

Both identified substitute parts meet these criteria and are suitable for direct replacement in applications where the RC5025F4222CS is specified.

Parameter Comparison

Engineering Selection Recommendations

RC5025F4222CS (Samsung Electro-Mechanics) — Primary Selection

The RC5025F4222CS maintains Active product status and is recommended for new designs and ongoing production. This part is currently in stock with 642 pieces available. The moisture-resistant thick film construction and unlimited MSL rating provide robust performance in standard industrial and consumer applications.

CRCW201042K2FKEF (Vishay Dale) — Preferred Substitute

The CRCW201042K2FKEF is the recommended substitute for the RC5025F4222CS. This part is Active and carries AEC-Q200 automotive qualification, providing additional reliability assurance. The higher power rating (0.75W vs. 0.667W) offers design margin without affecting electrical performance. Inventory availability is strong at 16,785 pieces. The maximum seated height of 0.028" (0.70mm) is marginally higher than the Samsung part but remains within typical PCB assembly tolerances for 2010 package components.

ERJ-12SF4222U (Panasonic Electronic Components) — Legacy Substitute

The ERJ-12SF4222U meets all electrical and mechanical substitution criteria and carries AEC-Q200 automotive qualification. However, this part is designated "Not For New Designs," indicating Panasonic has discontinued active development. This part should be used only for legacy system maintenance or repair applications where supply continuity is already established. Current inventory is 5,377 pieces.

Frequently Asked Questions (FAQ)

Q: Can CRCW201042K2FKEF or ERJ-12SF4222U be used as direct replacements for RC5025F4222CS?

A: Yes. Both substitute parts match the critical electrical parameters (42.2 kOhms, ±1% tolerance, ±100 ppm/°C temperature coefficient, -55°C to 155°C operating range) and mechanical specifications (2010 package, 2 terminations, identical footprint dimensions). The higher power ratings (0.75W vs. 0.667W) are acceptable and provide additional thermal margin.

Q: What is the difference in physical dimensions between these parts?

A: All three parts share identical length and width (0.197" L x 0.098" W / 5.00mm x 2.50mm). The seated height differs slightly: RC5025F4222CS is 0.026" (0.66mm) maximum, while both CRCW201042K2FKEF and ERJ-12SF4222U are 0.028" (0.70mm) maximum. This 0.002" (0.04mm) difference is negligible for standard PCB assembly and does not affect component placement or soldering.

Q: Are all three parts RoHS3 compliant?

A: Yes. RC5025F4222CS, CRCW201042K2FKEF, and ERJ-12SF4222U are all ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), making them suitable for unrestricted storage and handling.

Q: Why do the substitute parts have higher power ratings?

A: The CRCW201042K2FKEF and ERJ-12SF4222U are rated at 0.75W (3/4W) compared to the RC5025F4222CS at 0.667W (2/3W). Both are manufactured in the same 2010 package using thick film composition. The higher power rating reflects the manufacturer's thermal design and does not affect electrical performance. In applications where the RC5025F4222CS is specified, the higher-rated substitutes provide equivalent or superior performance.

Q: Should I use ERJ-12SF4222U for new designs?

A: No. The ERJ-12SF4222U is designated "Not For New Designs" by Panasonic. For new product development, use either the RC5025F4222CS (Samsung) or CRCW201042K2FKEF (Vishay Dale). The ERJ-12SF4222U is appropriate only for maintenance, repair, or legacy system support where existing supply agreements are in place.

Q: What certifications do these parts carry?

A: RC5025F4222CS carries ROHS3 compliance and unlimited MSL rating. CRCW201042K2FKEF and ERJ-12SF4222U both carry ROHS3 compliance, unlimited MSL rating, and AEC-Q200 automotive qualification, indicating enhanced reliability testing for automotive applications.
