RCS3216F2152CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F2152CS is a 21.5 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 currently active in production with 717 pieces in stock inventory.

Equivalent and substitute parts are identified when designs require alternative sourcing due to supply constraints, inventory availability, or specific application requirements while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F2152CS is determined by strict equivalence across the following critical parameters:

• Resistance Value: 21.5 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)
• Terminations: 2 (exact match required)
• Compliance: ROHS3 Compliant, MSL 1 (Unlimited)

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in packaging format (Tape & Reel vs. Cut Tape) do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

Primary Selection (Active Status)

For new designs and ongoing production, select from the following active-status alternatives:

• CR1206-FX-2152ELF (Bourns Inc.): Active product with 30,867 units in stock. Moisture-resistant thick film composition. Suitable for general applications.

• CRCW120621K5FKEA (Vishay Dale): Active product with 55,499 units in stock. Automotive AEC-Q200 rated. Recommended for automotive and high-reliability applications requiring AEC-Q200 qualification.

• RC1206FR-0721K5L (YAGEO): Active product with 18,968 units in stock. Moisture-resistant thick film composition. Suitable for general applications.

Secondary Selection (Legacy Status)

• ERJ-8ENF2152V (Panasonic Electronic Components): Marked "Not For New Designs" with 59,486 units in stock. Automotive AEC-Q200 rated. Use only for legacy design maintenance or replacement applications where existing qualification exists.

Compliance Considerations

All substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. All parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-2152ELF replace RCS3216F2152CS in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (21.5 kOhms), tolerance (±1%), power rating (0.25W), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Physical dimension variations (height: 0.030" vs. 0.026") remain within 1206 package specification tolerances.

Q: What is the difference between Bourns CR1206-FX-2152ELF and Vishay CRCW120621K5FKEA?

A: Both are electrically identical. The primary difference is that CRCW120621K5FKEA carries Automotive AEC-Q200 qualification, making it suitable for automotive applications. CR1206-FX-2152ELF is specified for general applications. Both are active products with high inventory availability.

Q: Why is ERJ-8ENF2152V marked "Not For New Designs"?

A: Panasonic has designated this part as legacy. While it remains electrically and mechanically equivalent and is available in stock (59,486 units), it should not be selected for new design implementations. Use only for replacement or maintenance of existing designs already using this part number.

Q: Are packaging format differences (Tape & Reel vs. Cut Tape) significant for substitution?

A: No. Packaging format differences do not affect electrical or mechanical compatibility. CR1206-FX-2152ELF and ERJ-8ENF2152V are supplied in Tape & Reel format, while CRCW120621K5FKEA is supplied in Cut Tape & Digi-Reel format. Selection should be based on assembly process requirements, not component performance.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) rating. All are classified as EAR99 for export control purposes. Compliance status is identical across all alternatives.

Q: What is the inventory status for each substitute?

A: CR1206-FX-2152ELF: 30,867 units; CRCW120621K5FKEA: 55,499 units; ERJ-8ENF2152V: 59,486 units; RC1206FR-0721K5L: 18,968 units. All parts are available as new original stock.
