RC6432F1372CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F1372CS is a 13.7 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film resistor is designed for general-purpose applications requiring moisture resistance and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package type and dimensions), and environmental performance characteristics. Substitute parts listed in this reference maintain functional equivalence within the specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1372CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 13.7 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 1W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C to 155°C (exact match)

Mechanical Equivalence Requirements:

• Package designation: 2512 (6432 Metric)
• Number of terminations: 2
• Physical dimensions compatible within specified tolerances

Environmental & Compliance Equivalence:

• Composition: Thick Film
• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed meet these criteria and are therefore functionally interchangeable with the RC6432F1372CS in applications where the specified electrical and mechanical parameters are required.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The RC6432F1372CS, CRCW251213K7FKEG, and RMCF2512FT13K7 all maintain Active product status and are suitable for new designs. These three parts are electrically and mechanically equivalent and may be selected based on availability, packaging format preference (tape & reel versus alternative packaging), and supply chain considerations.

Secondary Selection (Legacy Applications): The ERJ-1TNF1372U is marked as "Not For New Designs" and should be used only in applications requiring replacement of existing components or in legacy system maintenance where continuity with original specifications is necessary.

Compliance Considerations: All substitute parts are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1), meeting the environmental and regulatory requirements of the original RC6432F1372CS. Automotive-rated variants (CRCW251213K7FKEG, ERJ-1TNF1372U, RMCF2512FT13K7) carry AEC-Q200 certification, providing additional qualification for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW251213K7FKEG replace RC6432F1372CS in all applications?

A: Yes. Both parts share identical electrical specifications (13.7 kOhms, ±1%, 1W), operate across the same temperature range (-55°C to 155°C), use thick film composition, and are packaged in the 2512 (6432 Metric) format. Both are ROHS3 compliant with MSL 1 rating. The primary difference is packaging format (tape & reel for CRCW versus standard packaging for RC) and manufacturer. CRCW251213K7FKEG carries AEC-Q200 automotive qualification, which the RC6432F1372CS does not specify.

Q: What is the difference between the Samsung RC6432F1372CS and Stackpole RMCF2512FT13K7?

A: Both parts are electrically and mechanically equivalent with matching resistance (13.7 kOhms), tolerance (±1%), power rating (1W), package type (2512), and operating temperature range (-55°C to 155°C). Physical dimensions are identical (0.248" L x 0.126" W, 6.30mm x 3.20mm). Both are Active products and ROHS3 compliant. The RMCF2512FT13K7 includes AEC-Q200 automotive qualification. Selection between these parts depends on supplier availability and application requirements.

Q: Why is ERJ-1TNF1372U marked "Not For New Designs"?

A: The ERJ-1TNF1372U is a legacy part from Panasonic Electronic Components. While it maintains full electrical and mechanical equivalence to the RC6432F1372CS and meets all specified parameters, its "Not For New Designs" status indicates that Panasonic is not recommending this part for new product development. This part should be reserved for replacement applications or legacy system support where original component continuity is required.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within manufacturing tolerances. The RC6432F1372CS and RMCF2512FT13K7 share identical length (0.248" / 6.30mm) and width (0.126" / 3.20mm). The CRCW251213K7FKEG has width of 0.124" (3.15mm) and the ERJ-1TNF1372U has length of 0.252" (6.40mm). These variations remain within the 2512 package specification and do not affect functional compatibility or PCB layout considerations for standard applications.

Q: Which substitute part should be selected for automotive applications?

A: For automotive applications, CRCW251213K7FKEG (Vishay Dale), ERJ-1TNF1372U (Panasonic), and RMCF2512FT13K7 (Stackpole) all carry AEC-Q200 certification. Among these, CRCW251213K7FKEG and RMCF2512FT13K7 maintain Active product status and are preferred for new automotive designs. The RC6432F1372CS does not specify AEC-Q200 qualification.

Q: What packaging formats are available for these substitute parts?

A: The RC6432F1372CS is available in standard packaging. CRCW251213K7FKEG, ERJ-1TNF1372U, and RMCF2512FT13K7 are supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes.
