RCS3216F3161CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F3161CS is a 3.16 kOhms ±1% 0.25W chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. 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 component is ROHS3 compliant with MSL 1 rating and is currently in active production status with 854 pieces in stock.

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements necessitate alternative sourcing from qualified manufacturers. Substitute components must maintain electrical equivalence across resistance value, tolerance, power rating, and package dimensions while meeting applicable compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3161CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value must be 3.16 kOhms with ±1% tolerance. Power dissipation capability must be 0.25W minimum. Temperature coefficient must be ±100ppm/°C or better. Operating temperature range must encompass -55°C to 155°C.

Mechanical Parameters: Package designation must be 1206 (3216 Metric). Physical dimensions (length, width, height) must be compatible with 1206 footprints. Number of terminations must be 2.

Material & Composition: Thick film construction is required. Moisture resistance is a qualifying feature.

Compliance Parameters: ROHS3 compliance is mandatory. MSL 1 rating is required. REACH unaffected status must be maintained.

All four substitute parts listed meet these criteria and are therefore electrically and mechanically interchangeable with the RCS3216F3161CS in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): CR1206-FX-3161ELF (Bourns Inc.), CRCW12063K16FKEA (Vishay Dale), and RC1206FR-073K16L (YAGEO) are all in active production status and are recommended for new designs and ongoing production applications. All three maintain full ROHS3 compliance and REACH unaffected status.

Automotive Applications: CRCW12063K16FKEA (Vishay Dale) and ERJ-8ENF3161V (Panasonic) carry AEC-Q200 automotive qualification. CRCW12063K16FKEA is preferred for automotive applications due to active product status.

Legacy/Existing Designs: ERJ-8ENF3161V (Panasonic Electronic Components) is marked as "Not For New Designs" but remains available with substantial inventory (94121 pieces). This part is suitable only for sustaining production of existing designs or where design freeze conditions apply.

Supply Chain Considerations: All substitute parts demonstrate adequate inventory levels. CR1206-FX-3161ELF offers the highest inventory position at 20055 pieces, followed by CRCW12063K16FKEA at 16867 pieces and RC1206FR-073K16L at 17926 pieces.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-3161ELF replace RCS3216F3161CS in my circuit?

A: Yes. Both components are electrically and mechanically equivalent with identical resistance (3.16 kOhms), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between CRCW12063K16FKEA and the other substitutes?

A: CRCW12063K16FKEA includes AEC-Q200 automotive qualification, making it suitable for automotive applications. All other electrical and mechanical parameters are equivalent to the other substitutes and the primary part.

Q: Why is ERJ-8ENF3161V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued this part for new design applications. However, it remains available for sustaining production of existing designs. New designs should use CR1206-FX-3161ELF, CRCW12063K16FKEA, or RC1206FR-073K16L.

Q: Are there physical dimension differences between these parts?

A: All parts conform to the 1206 (3216 Metric) package standard. Minor variations exist in maximum seated height: RCS3216F3161CS (0.66mm), CR1206-FX-3161ELF (0.75mm), CRCW12063K16FKEA (0.60mm), ERJ-8ENF3161V (0.70mm), and RC1206FR-073K16L (0.65mm). These variations are within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Which substitute has the best availability?

A: ERJ-8ENF3161V has the highest inventory at 94121 pieces. However, due to its "Not For New Designs" status, CR1206-FX-3161ELF (20055 pieces) is recommended for new applications, with CRCW12063K16FKEA (16867 pieces) and RC1206FR-073K16L (17926 pieces) as secondary options.

Q: Do all substitutes meet the same compliance requirements?

A: Yes. All five parts (primary and four substitutes) are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. CRCW12063K16FKEA and ERJ-8ENF3161V additionally carry AEC-Q200 automotive certification.
