RCS3216F1741CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F1741CS is a 1.74 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 properties, operating across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The component is RoHS3 compliant with MSL 1 (Unlimited) rating and REACH unaffected status.

Substitute parts are identified when they share identical electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package type and dimensions), and environmental compliance. Alternative sources become necessary for supply chain optimization, inventory management, or when the primary manufacturer part reaches end-of-life status.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence: Resistance value (1.74 kOhms), tolerance (±1%), and power rating (0.25W) must be identical.

Mechanical Compatibility: Package designation (1206 / 3216 Metric) and termination count (2) must match. Physical dimensions (length, width, height) must be compatible with PCB footprints designed for 1206 packages.

Environmental & Compliance Alignment: Operating temperature range (-55°C ~ 155°C), temperature coefficient (±100ppm/°C), RoHS3 compliance, and MSL 1 rating must be maintained.

Composition & Construction: Thick film construction is required for all substitutes.

All four substitute parts listed meet these criteria and are direct functional equivalents to the RCS3216F1741CS.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status):

CR1206-FX-1741ELF (Bourns Inc.) and RC1206FR-071K74L (YAGEO) are recommended as primary substitutes. Both maintain Active product status with full manufacturer support and are suitable for new design implementations. Bourns CR1206-FX-1741ELF offers the highest inventory availability (25,789 pcs) for supply chain continuity.

Automotive-Qualified Alternative:

CRCW12061K74FKEA (Vishay Dale) is qualified to AEC-Q200 automotive standards, providing enhanced reliability for automotive and harsh-environment applications. This part is appropriate when automotive-grade specifications are required by design or regulatory requirements.

Legacy Compatibility:

ERJ-8ENF1741V (Panasonic Electronic Components) carries "Not For New Designs" status and should be used only for replacement or repair of existing assemblies. This part maintains full electrical and mechanical compatibility but is not recommended for new product development.

Compliance Verification:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical environmental ratings. Selection between active alternatives should be based on supply availability, lead time, packaging format (Tape & Reel), and cost considerations specific to procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-1741ELF replace RCS3216F1741CS directly on the PCB?

A: Yes. Both parts use the 1206 (3216 Metric) package with identical electrical specifications (1.74 kOhms ±1%, 0.25W). Physical dimensions are compatible with standard 1206 PCB footprints. No circuit redesign is required.

Q: What is the difference between the Bourns and YAGEO substitutes?

A: CR1206-FX-1741ELF (Bourns) and RC1206FR-071K74L (YAGEO) are electrically and mechanically identical. The primary differences are manufacturer, packaging format (both Tape & Reel), and inventory availability. Bourns offers significantly higher stock levels (25,789 pcs vs. 8,422 pcs).

Q: Why is ERJ-8ENF1741V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has discontinued active development and support for this product line. While the part remains functionally equivalent and in stock, it should be reserved for maintenance and repair of existing products rather than incorporated into new designs.

Q: Should I use CRCW12061K74FKEA for non-automotive applications?

A: CRCW12061K74FKEA is suitable for any application. The AEC-Q200 automotive qualification represents an additional quality assurance level and does not restrict use to automotive circuits. Selection should be based on availability and cost rather than application type.

Q: Are there dimensional differences between these substitutes?

A: All parts conform to the 1206 package standard (0.126" L x 0.063" W / 3.20mm x 1.60mm). Height variations are minor (0.024" to 0.030" / 0.60mm to 0.75mm) and fall within standard PCB assembly tolerances. These differences do not affect PCB compatibility or assembly processes.

Q: Do all substitutes have the same moisture sensitivity rating?

A: Yes. All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Storage, handling, and reflow processes are identical across all alternatives.

Q: Can I mix different manufacturers in the same assembly?

A: Yes. All substitute parts meet identical electrical, mechanical, and environmental specifications. Mixed sourcing is acceptable from an engineering standpoint. Verify procurement and quality assurance procedures with your supply chain management.
