RCS3216F1371CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F1371CS is a 1.37 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status with anti-sulfur and moisture-resistant characteristics. The part is ROHS3 compliant and operates across -55°C to 155°C temperature range.

Substitute parts are identified when electrical specifications (resistance value, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical parameters (package type, dimensions, termination count) are identical or functionally equivalent. This reference provides qualified alternatives from multiple manufacturers for procurement flexibility and supply chain continuity.

Substitute Part Grouping Explanation

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

Electrical Equivalence Requirements:

Resistance value: 1.37 kOhms (exact match)
Tolerance: ±1% (exact match)
Power rating: 0.25W / 1/4W (exact match)
Temperature coefficient: ±100ppm/°C (exact match)
Operating temperature range: -55°C ~ 155°C (exact match)
Composition: Thick Film (exact match)

Mechanical Equivalence Requirements:

Package type: 1206 (3216 Metric) (exact match)
Number of terminations: 2 (exact match)
Moisture Sensitivity Level: 1 (Unlimited) (exact match)

Compliance Requirements:

RoHS3 Compliant (mandatory)
REACH Unaffected (mandatory)

All five substitute parts listed meet these criteria. Variations in physical dimensions (length, width, height) within standard manufacturing tolerances do not disqualify substitution, as these fall within acceptable PCB footprint compatibility for 1206 package specifications.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

AC1206FR-071K37L (YAGEO), CR1206-FX-1371ELF (Bourns Inc.), CRCW12061K37FKEA (Vishay Dale), and RC1206FR-071K37L (YAGEO) are all classified as Active products and are suitable for new designs and production applications. These parts carry identical electrical and mechanical specifications to the RCS3216F1371CS.

Secondary Substitute (Legacy Status):

ERJ-8ENF1371V (Panasonic Electronic Components) is classified as "Not For New Designs." This designation indicates the manufacturer has discontinued active development for this part number. While electrically and mechanically equivalent, this part should be used only for replacement or maintenance of existing assemblies, not for new product development.

Compliance Considerations:

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Parts with AEC-Q200 automotive qualification (AC1206FR-071K37L, CRCW12061K37FKEA, ERJ-8ENF1371V) provide additional reliability assurance for automotive and high-reliability applications, though this certification is not required for general industrial use.

Inventory Availability:

CR1206-FX-1371ELF offers the highest inventory level (20,712 pcs), followed by CRCW12061K37FKEA (14,744 pcs) and ERJ-8ENF1371V (69,629 pcs). Selection based on supply chain requirements and lead time considerations is appropriate.

Frequently Asked Questions (FAQ)

Q: Can I substitute RCS3216F1371CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts meet identical electrical specifications (1.37 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and mechanical requirements (1206 package, 2 terminations). PCB footprint compatibility is maintained across all substitutes.

Q: What is the difference between Active and "Not For New Designs" product status?

A: Active status indicates the manufacturer continues production and supports the part for new applications. "Not For New Designs" indicates the manufacturer has discontinued active development; the part remains available for existing product maintenance but should not be selected for new designs. ERJ-8ENF1371V carries this designation.

Q: Are there differences in physical dimensions between substitute parts?

A: Minor variations exist within standard manufacturing tolerances. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), and height ranges from 0.024" to 0.030" (0.60mm to 0.75mm). These variations are within 1206 package specifications and do not affect PCB footprint compatibility.

Q: Which substitute parts have automotive qualification?

A: AC1206FR-071K37L (YAGEO), CRCW12061K37FKEA (Vishay Dale), and ERJ-8ENF1371V (Panasonic) carry AEC-Q200 automotive qualification. The RCS3216F1371CS (Samsung) and CR1206-FX-1371ELF (Bourns) do not list this certification.

Q: What is Moisture Sensitivity Level (MSL) 1, and why is it important?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts, including the main part, carry this rating, eliminating moisture-related procurement or storage constraints.

Q: Can I mix different substitute parts in the same production batch?

A: Yes. All substitute parts are electrically and mechanically equivalent. However, standard manufacturing practice recommends using a single part number per production batch to maintain traceability and simplify quality documentation.

Q: What does ROHS3 compliance mean?

A: ROHS3 (Restriction of Hazardous Substances Directive 3) compliance certifies that the component contains no more than specified maximum concentrations of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, or polybrominated diphenyl ethers. All listed parts meet this requirement.
