RCS3216F2742CS Equivalent & Substitute Parts

Part Overview

The RCS3216F2742CS is a 27.4 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 a temperature coefficient of ±100ppm/°C. The component is RoHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and environmental ratings align with the original component, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F2742CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (27.4 kOhms), tolerance (±1%), and power rating (0.25W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (1206 / 3216 Metric) and physical dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm) ensure PCB footprint compatibility. Height variation within seated maximum specifications does not affect substitutability.

Environmental & Compliance Requirements: RoHS3 compliance, MSL 1 rating, and REACH unaffected status are mandatory for direct substitution. Composition (thick film) and termination count (2) must match.

Product Status Consideration: Active status components are preferred for new designs. Components marked "Not For New Designs" remain functionally equivalent but may have limited future availability.

All identified substitute parts meet these criteria without exception.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): CR1206-FX-2742ELF (Bourns Inc.) and CRCW120627K4FKEA (Vishay Dale) are both active products suitable for new design implementations. Both maintain full electrical and mechanical equivalence to the RCS3216F2742CS. CRCW120627K4FKEA carries AEC-Q200 automotive qualification, appropriate for applications requiring automotive-grade reliability. CR1206-FX-2742ELF provides standard industrial-grade performance with moisture-resistant construction.

Secondary Selection (Legacy Status): ERJ-8ENF2742V (Panasonic Electronic Components) is electrically and mechanically equivalent but carries "Not For New Designs" status. This component remains suitable for replacement applications, repair, or legacy system maintenance where existing inventory exists. AEC-Q200 qualification is available.

Compliance Verification: All substitute parts maintain RoHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory alignment with the original component across all jurisdictions.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-2742ELF directly replace RCS3216F2742CS on existing PCBs?

A: Yes. Both components share identical electrical specifications (27.4 kOhms ±1%, 0.25W), package designation (1206), and physical dimensions (0.126" L x 0.063" W). Height variation (0.030" vs 0.026" seated maximum) does not affect PCB assembly compatibility. All compliance certifications align.

Q: What is the difference between CRCW120627K4FKEA and CR1206-FX-2742ELF?

A: Both are electrically and mechanically equivalent. CRCW120627K4FKEA includes AEC-Q200 automotive qualification and has a lower seated height (0.024" vs 0.030"). CR1206-FX-2742ELF is standard industrial-grade. Selection depends on application requirements and automotive certification necessity.

Q: Why is ERJ-8ENF2742V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active promotion for new applications. The component remains functionally equivalent and suitable for replacement or legacy system support. For new designs, CR1206-FX-2742ELF or CRCW120627K4FKEA are recommended.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification, matching the original RCS3216F2742CS. MSL 1 (Unlimited) moisture sensitivity rating is consistent across all options.

Q: Does package type (Tape & Reel vs other packaging) affect substitutability?

A: No. Packaging format (Tape & Reel) affects supply chain and handling procedures but does not alter electrical or mechanical compatibility. The component itself remains functionally identical regardless of packaging presentation.

Q: Can these resistors be used in high-temperature applications?

A: Yes. All components operate across -55°C to 155°C with ±100ppm/°C temperature coefficient, supporting high-temperature industrial and automotive environments within specified limits.
