Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025J754CS are identified based on strict electrical and mechanical parameter matching:

Electrical Compatibility Criteria:

• Resistance value must equal 750 kOhms
• Tolerance of ±1% is acceptable (tighter than ±5% requirement)
• Power rating of 0.75W (3/4W) exceeds the 0.667W minimum requirement
• Temperature coefficient of ±100ppm/°C matches the original specification
• Operating temperature range of -55°C ~ 155°C maintains full compatibility

Mechanical Compatibility Criteria:

• Package type 2010 (5025 Metric) must match for PCB footprint alignment
• Physical dimensions 0.197" L x 0.098" W (5.00mm x 2.50mm) are identical
• Thick film composition maintains construction consistency
• Number of terminations (2) is identical

Regulatory & Environmental Criteria:

• RoHS3 Compliance required
• MSL 1 (Unlimited) moisture sensitivity level acceptable
• REACH Unaffected status maintained

Substitute parts meeting all these criteria are functionally and mechanically interchangeable with the RC5025J754CS in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

CRCW2010750KFKEF (Vishay Dale) is the primary substitute for new designs and production applications. This part maintains Active product status, meets all electrical and mechanical parameters, and provides improved tolerance specification (±1% versus ±5%). The higher power rating (0.75W) provides additional thermal margin. Automotive AEC-Q200 qualification indicates enhanced reliability testing and is suitable for demanding environments.

ERJ-12SF7503U (Panasonic Electronic Components) is functionally equivalent but carries Not For New Designs product status. This classification indicates the manufacturer is discontinuing or has discontinued active promotion of this part number. While electrically and mechanically compatible, this part should be used only for replacement or repair of existing assemblies where design continuity is required. New circuit designs should utilize CRCW2010750KFKEF or the original RC5025J754CS.

Both substitute parts are RoHS3 compliant, REACH unaffected, and maintain identical operating temperature ranges and moisture sensitivity ratings as the original component.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010750KFKEF replace RC5025J754CS in existing designs?

A: Yes. Both parts share identical resistance value (750 kOhms), package type (2010/5025 Metric), physical dimensions, temperature coefficient, and operating temperature range. The substitute offers tighter tolerance (±1% versus ±5%) and higher power rating (0.75W versus 0.667W), making it functionally superior for the same circuit application.

Q: What is the difference between the two substitute parts?

A: CRCW2010750KFKEF and ERJ-12SF7503U are electrically and mechanically identical. The primary difference is product status: CRCW2010750KFKEF is Active, while ERJ-12SF7503U is Not For New Designs. For new circuit designs, CRCW2010750KFKEF is the recommended choice.

Q: Are there height differences between these parts?

A: The original RC5025J754CS has a maximum seated height of 0.026" (0.66mm), while both substitutes have 0.028" (0.70mm). This 0.002" (0.04mm) difference is negligible for standard PCB assembly and does not affect footprint compatibility or clearance in typical applications.

Q: Do all three parts have the same moisture sensitivity rating?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture baking requirements. Storage and handling procedures are identical across all three part numbers.

Q: Are automotive applications supported by these substitutes?

A: Both substitute parts carry AEC-Q200 automotive qualification. The original RC5025J754CS does not list this qualification. If automotive-grade components are required, CRCW2010750KFKEF or ERJ-12SF7503U provide this additional certification.

Q: What is the significance of the ±1% tolerance in the substitutes?

A: The substitute parts offer ±1% tolerance compared to ±5% for the original. This means the actual resistance value will be closer to the nominal 750 kOhms specification. In circuits where tighter resistance tolerance improves performance or reduces calibration requirements, the substitutes provide this advantage.
