RCS3216F1621CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F1621CS is a 1.62 kOhms ±1% 0.25W (1/4W) 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 part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating) and mechanical compatibility (package size, termination count, operating temperature range). Substitutes may vary in specific features (such as automotive qualification or pulse withstanding capability) while maintaining core functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F1621CS is determined by the following mandatory parameters:

Core Electrical Parameters:

• Resistance value: 1.62 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W) minimum
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• Package: 1206 (3216 Metric)
• Terminations: 2
• Composition: Thick Film

Compliance Parameters:

• RoHS3 Compliant
• MSL 1 (Unlimited)

Substitute parts are grouped into two categories:

Category A - Direct Equivalents (0.25W Rating): Parts with identical power rating (0.25W/1/4W) and all core parameters matching. These include CR1206-FX-1621ELF (Bourns), CRCW12061K62FKEA (Vishay Dale), ERJ-8ENF1621V (Panasonic), RC1206FR-071K62L (YAGEO), and RMCS1206FT1K62 (Stackpole).

Category B - Higher Power Rating (0.75W Rating): CRCW12061K62FKEAHP (Vishay Dale) provides 0.75W (3/4W) capability in the same 1206 package, enabling use in applications requiring higher power dissipation while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: Select from parts with Active product status: CR1206-FX-1621ELF, CRCW12061K62FKEA, CRCW12061K62FKEAHP, RC1206FR-071K62L, or RMCS1206FT1K62. All maintain full ROHS3 compliance and MSL 1 rating.

For Automotive Applications: CRCW12061K62FKEA and CRCW12061K62FKEAHP (Vishay Dale) carry AEC-Q200 automotive qualification. CRCW12061K62FKEAHP additionally provides pulse withstanding capability for automotive transient protection circuits.

For Legacy Design Continuation: ERJ-8ENF1621V (Panasonic) is marked "Not For New Designs" but remains available for existing production. This part carries AEC-Q200 qualification and maintains full electrical and mechanical compatibility.

For Higher Power Dissipation: CRCW12061K62FKEAHP provides 0.75W rating in the same 1206 package, suitable for applications requiring increased power handling while maintaining all other specifications.

For Anti-Sulfur Applications: Both RCS3216F1621CS (Samsung) and RMCS1206FT1K62 (Stackpole) feature anti-sulfur properties, addressing corrosive environments.

Frequently Asked Questions (FAQ)

Q: Can CRCW12061K62FKEAHP (0.75W) be used as a direct replacement for RCS3216F1621CS (0.25W)?

A: Yes. The 0.75W part is mechanically and electrically compatible. Higher power rating provides additional design margin and does not create incompatibility. The 1206 package dimensions, resistance value, tolerance, temperature coefficient, and operating range are identical. Use this substitution when circuit design permits or requires higher power dissipation capability.

Q: What is the difference between CR1206-FX-1621ELF and CRCW12061K62FKEA?

A: Both are 1.62 kOhms ±1% 0.25W 1206 resistors with identical electrical specifications. CR1206-FX-1621ELF (Bourns) features moisture resistance. CRCW12061K62FKEA (Vishay Dale) includes automotive AEC-Q200 qualification. Selection depends on application requirements: general industrial use favors Bourns; automotive applications require Vishay Dale.

Q: Why is ERJ-8ENF1621V marked "Not For New Designs"?

A: This Panasonic part remains available for existing production support but is not recommended for new circuit designs. Equivalent active alternatives with identical specifications are available from other manufacturers. For new designs, select from active status parts: CR1206-FX-1621ELF, CRCW12061K62FKEA, RC1206FR-071K62L, or RMCS1206FT1K62.

Q: Are all substitute parts MSL 1 (Unlimited)?

A: Yes. All listed substitute parts maintain MSL 1 rating, indicating unlimited shelf life and no moisture bake-out requirement prior to soldering.

Q: What is the significance of the height difference (0.60mm to 0.75mm)?

A: Height variation among 1206 package parts is within standard tolerance. All listed parts are mechanically compatible with standard 1206 PCB footprints. Height differences do not affect electrical performance or board assembly compatibility.

Q: Can I substitute based on packaging format (Tape & Reel vs. Cut Tape)?

A: Packaging format (Tape & Reel, Cut Tape, Digi-Reel) affects supply chain and handling but does not impact electrical or mechanical compatibility. Component selection should prioritize electrical and mechanical parameters; packaging format is a procurement consideration.

Q: Which substitute offers the best availability?

A: RC1206FR-071K62L (YAGEO) shows highest inventory (72,193 pcs). CRCW12061K62FKEA (Vishay Dale) provides 29,371 pcs. CR1206-FX-1621ELF (Bourns) offers 24,943 pcs. Availability may vary by distributor and time. Verify current stock with component suppliers.
