RCS3216F2942CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F2942CS is a 29.4 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 construction, operating across -55°C to 155°C with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is currently in active production status with 951 pieces available in inventory.

Substitute parts are identified when electrical specifications, mechanical dimensions, and environmental ratings align with the main part's functional requirements, enabling direct replacement in circuit designs without performance degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F2942CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 29.4 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within standard 1206 package tolerances and differences in packaging format (Tape & Reel vs. Cut Tape) do not affect functional substitutability. Product status and specific feature sets (automotive qualification, anti-sulfur coating) are noted for application-specific selection but do not prevent electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Designs: CRCW120629K4FKEA (Vishay Dale) and RC1206FR-0729K4L (YAGEO) are preferred substitutes. Both maintain active product status with full production support. CRCW120629K4FKEA includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. RC1206FR-0729K4L offers the highest inventory availability (62021 pieces) with moisture-resistant construction matching the original part's environmental specifications.

For Existing Designs in Production: RCS3216F2942CS (Samsung) remains the primary choice with 951 pieces in stock. CRCW120629K4FKEA and RC1206FR-0729K4L provide direct electrical and mechanical equivalence for supply chain continuity.

For Legacy or Maintenance Applications: ERJ-8ENF2942V (Panasonic) is electrically and mechanically equivalent but carries "Not For New Designs" status. This part is suitable only for replacement in existing systems where the original specification is maintained. New design implementations should not select this part.

Compliance Considerations: All four parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. MSL 1 rating across all parts ensures unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CRCW120629K4FKEA directly replace RCS3216F2942CS in existing PCB layouts?

A: Yes. Both parts share identical electrical specifications (29.4 kOhms ±1%, 0.25W, ±100ppm/°C) and package dimensions (1206 / 3216 Metric). Physical dimension variations (height: 0.026" vs. 0.024") fall within standard 1206 package tolerances and do not affect PCB assembly or circuit performance.

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

A: Tape & Reel (TR) packaging is used for automated pick-and-place assembly in high-volume production. Cut Tape (CT) is used for manual assembly or lower-volume applications. Both formats contain identical components; packaging selection depends on assembly process requirements, not electrical performance.

Q: Why is ERJ-8ENF2942V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has discontinued active development and production support for this part series. While electrically and mechanically equivalent, it should not be selected for new circuit designs. Existing designs currently using this part may continue with it for maintenance purposes.

Q: Are all substitute parts suitable for automotive applications?

A: CRCW120629K4FKEA carries AEC-Q200 automotive qualification. RCS3216F2942CS, ERJ-8ENF2942V, and RC1206FR-0729K4L do not list automotive ratings. For automotive applications requiring AEC-Q200 compliance, CRCW120629K4FKEA is the specified choice.

Q: What does MSL 1 (Unlimited) mean for component storage?

A: MSL 1 rating indicates the component has unlimited shelf life under standard storage conditions (typically 23°C ± 2°C, 45% ± 5% relative humidity). No baking or moisture precautions are required before assembly, simplifying inventory management and reducing component preparation time.

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

A: Yes. All four parts meet identical electrical and mechanical specifications. Mixed sourcing is acceptable for supply chain flexibility. However, maintain consistent part selection within individual PCB assemblies to simplify traceability and quality documentation.
