RCS3216F2372CS Equivalent & Substitute Parts

Part Overview

The RCS3216F2372CS is a 23.7 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is RoHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements mandate alternative manufacturer certifications such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F2372CS is determined by strict equivalence across the following parameters:

• Resistance Value: 23.7 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All four substitute parts listed meet these criteria. Physical dimensions (length, width, height) and additional certifications (such as AEC-Q200 automotive qualification) represent secondary differentiators that do not disqualify substitution but may influence selection based on application requirements.

Engineering Selection Recommendations

Primary Selection (Active Status, No Special Certifications Required):

For general-purpose applications without automotive qualification requirements, select from CR1206-FX-2372ELF (Bourns Inc.) or RC1206FR-0723K7L (YAGEO). Both parts maintain Active product status and provide equivalent electrical and thermal performance to the RCS3216F2372CS. The Bourns part offers maximum seated height of 0.030" (0.75mm), while the YAGEO part provides the most compact profile at 0.026" (0.65mm), matching the original Samsung part height.

Automotive Applications (AEC-Q200 Requirement):

For designs requiring automotive-grade components, CRCW120623K7FKEA (Vishay Dale) is the preferred substitute. This part carries AEC-Q200 certification and maintains Active product status. The Vishay part provides the lowest seated height at 0.024" (0.60mm), beneficial for space-constrained PCB layouts.

Legacy Design Continuation (Not For New Designs):

ERJ-8ENF2372V (Panasonic Electronic Components) carries "Not For New Designs" status and includes AEC-Q200 certification. This part is suitable only for sustaining production of existing designs and should not be selected for new development.

Compliance Verification:

All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental and regulatory compliance profile.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-2372ELF replace RCS3216F2372CS in any application?

A: Yes. CR1206-FX-2372ELF meets all electrical and mechanical substitution criteria. The 0.030" (0.75mm) seated height is 0.004" taller than the original part; verify PCB clearance in space-constrained designs.

Q: What is the difference between the Bourns and YAGEO substitutes?

A: Both CR1206-FX-2372ELF (Bourns) and RC1206FR-0723K7L (YAGEO) are electrically identical. The YAGEO part has a seated height of 0.026" (0.65mm), matching the original Samsung part exactly. The Bourns part measures 0.030" (0.75mm). Select based on PCB height constraints.

Q: Should I use CRCW120623K7FKEA for non-automotive applications?

A: CRCW120623K7FKEA is suitable for any application. The AEC-Q200 certification does not restrict use in non-automotive designs. This part offers the lowest seated height at 0.024" (0.60mm), making it advantageous for compact layouts.

Q: Why is ERJ-8ENF2372V marked "Not For New Designs"?

A: ERJ-8ENF2372V carries this status from Panasonic Electronic Components. This designation indicates the part is available for sustaining existing production but should not be selected for new product development. Use CR1206-FX-2372ELF, CRCW120623K7FKEA, or RC1206FR-0723K7L for new designs.

Q: Are all substitutes available in Tape & Reel packaging?

A: Yes. CR1206-FX-2372ELF, CRCW120623K7FKEA, ERJ-8ENF2372V, and RC1206FR-0723K7L are all supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Do substitute parts have identical moisture resistance properties?

A: All substitute parts carry MSL 1 (Unlimited) rating. CR1206-FX-2372ELF and RC1206FR-0723K7L are explicitly specified as moisture resistant. CRCW120623K7FKEA and ERJ-8ENF2372V carry AEC-Q200 automotive certification, which includes moisture resistance requirements. The original RCS3216F2372CS includes anti-sulfur and moisture-resistant features; substitutes meet or exceed these requirements.

Q: Can I mix different substitute parts in the same production batch?

A: All four substitutes are electrically and mechanically equivalent within the specified parameters. However, verify with your manufacturing partner that PCB assembly equipment can accommodate the height variations (0.024" to 0.030" seated height range) if mixing parts in the same batch.
