RCS3216J273CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216J273CS is a 27 kOhm ±5% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in 1206 (3216 Metric) package format. This component is classified as Active product status with anti-sulfur and moisture-resistant construction. The part is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical specifications (resistance value, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical compatibility (package type, termination count, physical dimensions) align with the main part. Alternative sources provide design flexibility, supply chain redundancy, and access to enhanced feature sets such as automotive qualification or improved tolerance grades.

Engineering Selection Recommendations

For Direct Replacement (±5% Tolerance):

AC1206JR-0727KL and RC1206JR-0727KL are functionally equivalent to RCS3216J273CS with identical tolerance and power specifications. Both are Active status products. AC1206JR-0727KL includes automotive AEC-Q200 qualification, providing enhanced reliability documentation for automotive applications. RC1206JR-0727KL offers standard industrial-grade moisture resistance without automotive certification.

For Enhanced Precision Applications (±1% Tolerance):

AC1206FR-0727KL, CR1206-FX-2702ELF, CRCW120627K0FKEA, and RC1206FR-0727KL provide tighter tolerance specifications while maintaining identical package, power rating, and temperature characteristics. All are Active status. AC1206FR-0727KL and CRCW120627K0FKEA carry AEC-Q200 automotive qualification. Selection between these options depends on packaging preference (Tape & Reel versus Cut Tape) and supply availability.

For Higher Power Dissipation:

CRCW120627K0FKEAHP provides 0.75W power rating in the same 1206 package with ±1% tolerance and AEC-Q200 qualification. This part is suitable for applications requiring increased thermal headroom while maintaining footprint compatibility.

Obsolescence Consideration:

ERJ-8ENF2702V carries "Not For New Designs" status and should be avoided for new product development despite high inventory availability. This designation indicates manufacturer discontinuation trajectory.

Compliance Verification:

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature range (-55°C ~ 155°C). No additional qualification or testing is required for direct substitution within the same tolerance class.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-0727KL replace RCS3216J273CS directly?

A: AC1206FR-0727KL is mechanically and electrically compatible. It provides superior tolerance (±1% versus ±5%) and includes automotive AEC-Q200 qualification. The tighter tolerance represents an enhancement rather than a limitation for most circuit applications. Verify circuit design does not depend on the ±5% tolerance band before substitution.

Q: What is the difference between AC1206JR-0727KL and RC1206JR-0727KL?

A: Both parts match RCS3216J273CS specifications exactly (27 kΩ, ±5%, 0.25W, 1206 package). AC1206JR-0727KL includes automotive AEC-Q200 qualification; RC1206JR-0727KL does not. Selection depends on application requirements and supply chain preferences.

Q: Why is CRCW120627K0FKEAHP listed as a substitute if it has 0.75W rating?

A: Higher power rating is a superset capability. The 0.75W part operates identically to 0.25W specifications in circuits designed for 0.25W dissipation. It provides additional thermal margin and is mechanically compatible with the 1206 footprint. Use this part when circuit layout or thermal conditions benefit from increased power handling.

Q: Is ERJ-8ENF2702V suitable for new designs?

A: No. ERJ-8ENF2702V carries "Not For New Designs" product status, indicating manufacturer end-of-life trajectory. Despite high inventory levels, this part should not be selected for new product development. Choose from Active status alternatives: AC1206FR-0727KL, CR1206-FX-2702ELF, CRCW120627K0FKEA, or RC1206FR-0727KL for ±1% tolerance; AC1206JR-0727KL or RC1206JR-0727KL for ±5% tolerance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original RCS3216J273CS specifications.

Q: What packaging options are available?

A: Substitute parts are supplied in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats. Verify packaging compatibility with assembly equipment before procurement. RC1206FR-0727KL and CRCW120627K0FKEA are available in Cut Tape format; AC1206FR-0727KL, AC1206JR-0727KL, RC1206JR-0727KL, CRCW120627K0FKEAHP, and ERJ-8ENF2702V are supplied in Tape & Reel format.

Q: Can tolerance be mixed in a single circuit?

A: Circuit design determines tolerance mixing feasibility. If the design accommodates ±5% component variation, mixing ±5% and ±1% parts is acceptable. If circuit performance depends on tighter tolerance bands, standardize on ±1% parts throughout. Consult circuit schematic and tolerance stack-up analysis.
