RCS3216F17R8CS Equivalent & Substitute Parts

Part Overview

The RCS3216F17R8CS is a 17.8 Ohm ±1% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This component features anti-sulfur and moisture-resistant properties, operating across the temperature range of -55°C to 155°C. The part maintains Active product status with 747 pieces currently in stock.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package type, dimensions, termination count), and environmental compliance (RoHS3, REACH status, MSL rating). Substitutes enable design flexibility, supply chain alternatives, and procurement optimization while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence: Resistance value (17.8 Ohms), tolerance (±1%), and power rating (0.25W) must match exactly. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) must be identical or superior.

Mechanical Compatibility: Package type must be 1206 (3216 Metric). Physical dimensions, height, and termination count (2 terminations) must be compatible with the original design footprint.

Environmental & Compliance: All substitutes must maintain ROHS3 compliance and REACH Unaffected status. Moisture Sensitivity Level (MSL) of 1 (Unlimited) is required.

Composition: Thick film construction is the standard for this category.

All four substitute parts listed below satisfy these criteria and are therefore electrically and mechanically interchangeable with the RCS3216F17R8CS.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

CR1206-FX-17R8ELF (Bourns Inc.), CRCW120617R8FKEA (Vishay Dale), and RC1206FR-0717R8L (YAGEO) are all Active products with full design-in support. These three parts are recommended for new designs and ongoing production applications. All maintain identical electrical specifications and full compliance certifications.

Automotive-Qualified Alternatives:

CRCW120617R8FKEA carries AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications requiring enhanced qualification documentation.

Legacy Consideration:

ERJ-8ENF17R8V (Panasonic Electronic Components) carries a "Not For New Designs" status. While electrically and mechanically equivalent, this part is designated for legacy system support and existing production only. New design implementations should utilize Active-status alternatives.

Supply Chain Optimization:

Inventory availability varies across substitutes. CRCW120617R8FKEA (15,710 pcs), ERJ-8ENF17R8V (51,083 pcs), and RC1206FR-0717R8L (10,278 pcs) offer alternative sourcing options when primary stock is constrained.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-17R8ELF replace RCS3216F17R8CS directly?

A: Yes. Both parts share identical electrical specifications (17.8 Ohms ±1%, 0.25W), operate across -55°C to 155°C, use 1206 package with 2 terminations, and maintain ROHS3 compliance and MSL 1 rating. Height difference (0.75mm vs 0.66mm) is within typical PCB design tolerances for 1206 components.

Q: What is the difference between the Vishay Dale CRCW120617R8FKEA and other substitutes?

A: CRCW120617R8FKEA includes AEC-Q200 automotive qualification. All other electrical and mechanical parameters are identical to the main part. This qualification is relevant only for automotive applications; general industrial applications do not require this certification.

Q: Why is ERJ-8ENF17R8V marked "Not For New Designs"?

A: This designation indicates the part is in legacy/mature phase. Panasonic continues to support existing production but does not recommend this part for new design implementations. Active alternatives (Bourns, Vishay Dale, YAGEO) should be prioritized for new projects.

Q: Are all substitutes available in Tape & Reel packaging?

A: Yes. All four substitute parts are supplied in Tape & Reel (TR) format, matching standard SMD production requirements.

Q: Do height variations affect PCB assembly compatibility?

A: Height variations among substitutes (0.60mm to 0.75mm) fall within standard 1206 component tolerances and do not affect PCB assembly processes or reflow profiles. All parts are compatible with standard pick-and-place equipment and reflow soldering.

Q: Which substitute offers the best inventory availability?

A: ERJ-8ENF17R8V provides the highest current stock (51,083 pcs). However, given its "Not For New Designs" status, CRCW120617R8FKEA (15,710 pcs) or RC1206FR-0717R8L (10,278 pcs) are preferred for active projects.
