RCS3216F3012CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F3012CS is a 30.1 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 properties. The part is ROHS3 compliant and suitable for general industrial and commercial applications requiring precision resistive elements with environmental protection.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design flexibility across multiple qualified sources is needed while maintaining identical electrical and mechanical performance specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3012CS is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

Resistance value: 30.1 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 0.25W, 1/4W (exact match required)
Package / Case: 1206 (3216 Metric) (exact match required)
Composition: Thick Film (exact match required)
Temperature Coefficient: ±100ppm/°C (exact match required)
Operating Temperature Range: -55°C to 155°C (exact match required)
Number of Terminations: 2 (exact match required)

Secondary Compliance Parameters:

RoHS Status: ROHS3 Compliant (preferred for regulatory alignment)

Engineering Selection Recommendations

Tier 1 - Direct Substitutes (Preferred):

CR1206-FX-3012ELF (Bourns Inc.), CRCW120630K1FKEA (Vishay Dale), RC1206FR-0730K1L (YAGEO), and RMCF1206FT30K1 (Stackpole Electronics Inc.) are electrically and mechanically equivalent to the RCS3216F3012CS. All four parts are Active product status, ROHS3 compliant, and meet all primary substitution criteria. These parts are suitable for direct replacement in new designs and existing applications.

Tier 2 - Conditional Substitutes:

CRCW120630K1FKEAHP (Vishay Dale) meets all primary substitution criteria but features a higher power rating of 0.75W instead of 0.25W. This part is electrically compatible and physically interchangeable in the 1206 package. Selection of this part is appropriate when additional thermal margin or pulse withstanding capability is required, though it is not necessary for applications designed for 0.25W operation.

Tier 3 - Legacy / Restricted Substitutes:

ERJ-8ENF3012V (Panasonic Electronic Components) meets all electrical and mechanical specifications and is ROHS3 compliant. However, this part carries a "Not For New Designs" product status designation. Use of this part is restricted to legacy system maintenance or replacement applications only.

CRCW120630K1FKTA (Vishay Dale) meets all electrical and mechanical specifications but is marked as RoHS non-compliant and REACH Affected. This part is not suitable for applications requiring regulatory compliance with current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can CRCW120630K1FKEAHP (0.75W) be used as a direct replacement for RCS3216F3012CS (0.25W)?

A: Yes. The CRCW120630K1FKEAHP is electrically and mechanically interchangeable. The higher power rating (0.75W vs. 0.25W) does not prevent substitution; it provides additional thermal capability. The part occupies the same 1206 package footprint and maintains identical resistance, tolerance, temperature coefficient, and operating temperature range. Physical dimensions are within acceptable tolerance for PCB assembly.

Q: What is the difference between the substitute parts in terms of packaging?

A: Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) affects supply chain logistics and handling but does not impact electrical or mechanical performance. All listed substitutes are available in standard industry packaging formats suitable for automated assembly processes.

Q: Why is ERJ-8ENF3012V marked "Not For New Designs"?

A: This designation indicates that the manufacturer (Panasonic) has discontinued active development and promotion of this product line. While the part remains electrically and mechanically equivalent, it is reserved for legacy system support and replacement applications. New designs should select from Tier 1 alternatives.

Q: Are there any dimensional differences between substitute parts that affect PCB layout?

A: All substitute parts conform to the 1206 (3216 Metric) package standard with identical length (0.126" / 3.20mm) and width (0.063" / 1.60mm). Height variations range from 0.60mm to 0.75mm maximum seated height. These variations are within standard PCB assembly tolerances and do not require layout modifications. Verify specific height requirements only if the application involves space-constrained stacking or proximity to adjacent components.

Q: Which substitute part offers the best compliance profile?

A: CR1206FR-0730K1L (YAGEO), CRCW120630K1FKEA (Vishay Dale), RMCF1206FT30K1 (Stackpole Electronics Inc.), and CR1206-FX-3012ELF (Bourns Inc.) all provide equivalent compliance. All four are ROHS3 compliant, REACH Unaffected, and Active product status. Selection among these four should be based on supply availability, lead time, and cost considerations rather than compliance differences.

Q: Can I use CRCW120630K1FKTA in a new design?

A: No. CRCW120630K1FKTA is RoHS non-compliant and REACH Affected. Current regulatory requirements for electronic components in most markets mandate RoHS3 compliance. This part is unsuitable for new designs and should be used only for legacy system maintenance where existing non-compliant designs are being serviced.
