RC6432F2372CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F2372CS is a 23.7 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film, moisture-resistant component operates across -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status with 1079 units in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the 2512 package format, allowing for design flexibility, supply chain optimization, or specific application requirements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2372CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 23.7 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 1W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Compatibility Requirements:

• Package format: 2512 (6432 Metric) (exact match)
• Composition: Thick Film (exact match)
• Number of terminations: 2 (exact match)

Compliance Requirements:

• RoHS3 compliance (mandatory)
• MSL 1 rating (unlimited moisture sensitivity)

All identified substitute parts meet these criteria. Dimensional variations within the 2512 package specification (length 0.248" ± tolerance, width 0.124"–0.126", height ≤0.028") are acceptable per IEC 60063 and EIA standards for this package class.

Engineering Selection Recommendations

Primary Selection: RC6432F2372CS (Samsung Electro-Mechanics)

Use the original Samsung part for new designs requiring standard industrial-grade thick film resistors. Active production status ensures long-term availability. Suitable for general-purpose applications where automotive qualification is not required.

Alternative Selection: CRCW251223K7FKEG (Vishay Dale)

Select this substitute when automotive-grade components are required. The CRCW series carries AEC-Q200 qualification, meeting automotive reliability standards. Active production status and higher inventory (1872 units) support sustained supply. Tape & Reel packaging accommodates high-volume manufacturing processes.

Legacy Alternative: ERJ-1TNF2372U (Panasonic Electronic Components)

This part maintains full electrical and mechanical equivalence but carries "Not For New Designs" status. Use only for replacement or repair of existing assemblies. AEC-Q200 qualification is available if automotive applications require legacy component compatibility. Tape & Reel packaging is standard.

Selection Criteria Summary:

• Standard applications: RC6432F2372CS
• Automotive applications: CRCW251223K7FKEG
• Legacy/repair applications: ERJ-1TNF2372U (existing designs only)

All three parts are ROHS3 compliant, MSL 1 rated, and operate identically across the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can CRCW251223K7FKEG replace RC6432F2372CS in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with 23.7 kOhms ±1% 1W ratings in the 2512 package. The CRCW series adds AEC-Q200 automotive qualification, which does not restrict use in non-automotive applications. Dimensional compatibility is maintained within 2512 package tolerances.

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

A: All three parts are electrically identical (23.7 kOhms ±1% 1W, ±100ppm/°C, -55°C to 155°C). Differences are: (1) Manufacturer and series designation; (2) Product status (RC6432F2372CS and CRCW251223K7FKEG are active; ERJ-1TNF2372U is not for new designs); (3) Automotive qualification (CRCW and ERJ-1TN carry AEC-Q200; RC does not specify); (4) Packaging format (CRCW and ERJ-1TN supplied in Tape & Reel; RC packaging not specified); (5) Inventory availability.

Q: Is the ERJ-1TNF2372U suitable for new product development?

A: No. Panasonic designates this part as "Not For New Designs." Use only for replacement or repair of existing assemblies. For new designs, select RC6432F2372CS or CRCW251223K7FKEG.

Q: Are dimensional differences between parts significant?

A: No. All parts conform to the 2512 (6432 Metric) package standard. Measured variations (length 0.248"–0.252", width 0.124"–0.126", height ≤0.028") fall within IEC 60063 and EIA package tolerances and do not affect PCB layout or assembly compatibility.

Q: Which part should I specify for automotive applications?

A: Specify CRCW251223K7FKEG or ERJ-1TNF2372U, both carrying AEC-Q200 qualification. CRCW251223K7FKEG is preferred for new automotive designs due to active production status.

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

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Are all parts ROHS3 compliant?

A: Yes. RC6432F2372CS, CRCW251223K7FKEG, and ERJ-1TNF2372U are all ROHS3 compliant and REACH unaffected.

Q: What is the temperature coefficient significance?

A: All parts share ±100ppm/°C temperature coefficient, ensuring identical resistance drift across the -55°C to 155°C operating range. This parameter is critical for precision analog circuits and must match exactly for substitution.
