Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F52R3CS is determined by strict alignment across the following criteria:

Electrical Parameters: Resistance value (52.3 Ohms), tolerance (±1%), power rating (1W), and temperature coefficient (±100ppm/°C) must be identical.

Thermal Parameters: Operating temperature range must span -55°C to 155°C minimum.

Mechanical Parameters: Package designation must be 2512 (6432 Metric) with compatible physical dimensions and termination count (2 terminations).

Material & Composition: Thick film construction is required.

Compliance & Environmental: ROHS3 compliance and MSL 1 rating must be maintained. REACH unaffected status applies.

The two substitute parts identified—CRCW251252R3FKEG (Vishay Dale) and ERJ-1TNF52R3U (Panasonic Electronic Components)—meet all electrical, mechanical, and compliance requirements. Both are thick film 2512 resistors with identical resistance, tolerance, power rating, and temperature coefficient specifications.

Parameter Comparison

Engineering Selection Recommendations

CRCW251252R3FKEG (Vishay Dale) is the primary substitute for new designs and production applications. This part maintains active product status, carries AEC-Q200 automotive qualification, and is available in high inventory (3030 pieces). All electrical, thermal, mechanical, and compliance parameters are identical to the RC6432F52R3CS. The Tape & Reel packaging format supports automated assembly processes.

ERJ-1TNF52R3U (Panasonic Electronic Components) is functionally equivalent but carries "Not For New Designs" status. This designation indicates the part is in mature or declining production phase. While all electrical and mechanical specifications match the original component and AEC-Q200 qualification is maintained, this part should be reserved for legacy system support, repair, or maintenance applications only. New design initiatives should prioritize CRCW251252R3FKEG.

Both substitutes are ROHS3 compliant with MSL 1 rating and REACH unaffected status, ensuring regulatory alignment with the original RC6432F52R3CS component.

Frequently Asked Questions (FAQ)

Q: Can CRCW251252R3FKEG directly replace RC6432F52R3CS in existing designs?

A: Yes. Both components share identical electrical specifications (52.3 Ohms ±1%, 1W, ±100ppm/°C), thermal range (-55°C to 155°C), 2512 package designation, and compliance certifications (ROHS3, MSL 1, REACH unaffected). Physical dimensions are compatible within specified tolerances.

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

A: CRCW251252R3FKEG (Vishay Dale) maintains active product status and is recommended for new designs. ERJ-1TNF52R3U (Panasonic) carries "Not For New Designs" status, indicating it is suitable only for legacy applications and repairs. Both are electrically and mechanically equivalent.

Q: Are there packaging differences between the main part and substitutes?

A: The RC6432F52R3CS is supplied in standard packaging. CRCW251252R3FKEG and ERJ-1TNF52R3U are supplied in Tape & Reel (TR) format, which is standard for automated assembly. All three components use the 2512 (6432 Metric) package with 2 terminations.

Q: Do the substitute parts meet automotive specifications?

A: CRCW251252R3FKEG and ERJ-1TNF52R3U both carry AEC-Q200 automotive qualification. The RC6432F52R3CS does not list AEC-Q200 in the provided specifications. If automotive qualification is required, CRCW251252R3FKEG is the appropriate selection.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements. All three components—RC6432F52R3CS, CRCW251252R3FKEG, and ERJ-1TNF52R3U—carry MSL 1 rating, eliminating moisture management concerns during storage and handling.

Q: Can ERJ-1TNF52R3U be used in new product development?

A: No. The "Not For New Designs" status indicates this part is in end-of-life phase. For new designs, CRCW251252R3FKEG is the appropriate substitute. ERJ-1TNF52R3U should be reserved for maintenance, repair, or legacy system support only.
