RC3225F2372CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F2372CS is a 23.7 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format. This component is rated for 0.333W (1/3W) power dissipation with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute components become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative electrical and mechanical specifications within acceptable tolerance ranges. The following equivalent parts maintain the critical electrical parameters while offering variations in power rating, packaging format, and automotive qualification levels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F2372CS is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters (Non-Negotiable):

• Resistance value: 23.7 kOhms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100 ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Power rating: Substitutes may exceed 0.333W (1/3W) provided the package dimensions remain compatible with 1210 form factor
• Packaging format: Original part supplied in bulk; substitutes may be supplied in Tape & Reel (TR) format
• Product status: Active or Not For New Designs status does not preclude substitution
• Automotive qualification: AEC-Q200 certification is an additional feature that does not disqualify substitution

The two identified substitute parts—ERJ-14NF2372U (Panasonic Electronic Components) and RMCF1210FT23K7 (Stackpole Electronics Inc)—satisfy all critical matching parameters while offering increased power ratings of 0.5W (1/2W) and automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

RMCF1210FT23K7 (Stackpole Electronics Inc) is the primary recommended substitute. This component maintains Active product status, ensuring continued availability and manufacturer support. The part carries AEC-Q200 automotive qualification, providing enhanced reliability documentation for applications requiring automotive-grade components. The increased power rating of 0.5W (1/2W) offers design margin beyond the original 0.333W specification while maintaining identical electrical characteristics and package compatibility.

ERJ-14NF2372U (Panasonic Electronic Components) functions as a secondary substitute option. Although this part carries Not For New Designs status, it remains electrically and mechanically equivalent to the primary part. The AEC-Q200 automotive qualification and 0.5W power rating provide identical functional benefits to the Stackpole alternative. Selection of this part should be limited to applications where existing inventory or supply chain relationships justify its use despite the discontinued design status.

Both substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity, matching the environmental and regulatory requirements of the original RC3225F2372CS component.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2372U be used as a direct replacement for RC3225F2372CS in new designs?

A: ERJ-14NF2372U meets all critical electrical and mechanical parameters required for substitution. However, the part carries Not For New Designs status from the manufacturer. For new design applications, RMCF1210FT23K7 is the recommended choice due to its Active product status and equivalent performance characteristics.

Q: What is the significance of the increased power rating in the substitute parts?

A: The substitute parts are rated for 0.5W (1/2W) compared to the original 0.333W (1/3W). This higher power rating provides additional thermal margin in the application. The increased rating does not alter electrical performance at the specified resistance and tolerance values. Applications designed for 0.333W operation will function identically with 0.5W-rated substitutes.

Q: Are the dimensional differences between parts significant?

A: The substitute parts (ERJ-14NF2372U and RMCF1210FT23K7) measure 0.126" L x 0.098" W (3.20mm x 2.50mm) with maximum seated height of 0.028" (0.70mm), compared to the original 0.126" L x 0.100" W (3.20mm x 2.55mm) with 0.026" (0.66mm) height. These dimensional variations remain within the 1210 (3225 Metric) package specification and are compatible with standard PCB footprints designed for this package format.

Q: What does AEC-Q200 qualification mean for component selection?

A: AEC-Q200 is an automotive industry standard qualification that documents component reliability under automotive operating conditions. Components carrying this certification have undergone additional testing and validation. For applications requiring automotive-grade components, RMCF1210FT23K7 and ERJ-14NF2372U both satisfy this requirement. For non-automotive applications, AEC-Q200 qualification is not a requirement but represents an additional quality assurance level.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes. All three parts—RC3225F2372CS, ERJ-14NF2372U, and RMCF1210FT23K7—share identical 1210 (3225 Metric) package footprints, electrical specifications (23.7 kOhms ±1%), and operating temperature ranges (-55°C to 155°C). The minor dimensional variations fall within standard PCB design tolerances and do not affect assembly compatibility.

Q: What is the difference between bulk and Tape & Reel packaging?

A: The original RC3225F2372CS is supplied in bulk packaging format. The substitute parts ERJ-14NF2372U and RMCF1210FT23K7 are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. Tape & Reel packaging provides the same component quality and performance; the difference is in handling and assembly methodology. Bulk-to-TR conversion does not affect electrical or mechanical properties.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC3225F2372CS, ERJ-14NF2372U, and RMCF1210FT23K7 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level. All parts meet current environmental and regulatory requirements for commercial and industrial applications.
