RCS3216F432CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F432CS is a 4.3 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component features anti-sulfur and moisture-resistant construction, operating across -55°C to 155°C with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is currently in active production status with 656 pieces available in inventory.

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements mandate specific certifications such as automotive AEC-Q200 qualification or alternative packaging formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F432CS is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 4.3 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All four substitute parts listed meet these critical parameters. Variations exist in physical dimensions (length and height), manufacturer-specific features (automotive AEC-Q200 certification), and packaging format (Tape & Reel versus Cut Tape). These variations do not affect functional substitution but may influence procurement, assembly, and application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Applications:

AC1206FR-074K3L (YAGEO) and CRCW12064K30FKEA (Vishay Dale) are preferred substitutes. Both parts maintain active product status, carry AEC-Q200 automotive qualification, and demonstrate higher inventory availability. CRCW12064K30FKEA offers the largest stock position (35203 pieces) and supports multiple packaging options including Cut Tape and Digi-Reel formats.

RC1206FR-074K3L (YAGEO) serves as a secondary substitute with active status and substantial inventory (47340 pieces). This part omits automotive AEC-Q200 certification but retains moisture-resistant construction and all critical electrical parameters.

For Legacy or Constrained Applications:

ERJ-8ENF4301V (Panasonic) carries "Not For New Designs" status and should be used only when existing designs mandate this specific part number or when supply of active alternatives is unavailable. Despite discontinued status for new designs, this part maintains AEC-Q200 certification and the highest inventory level (91758 pieces).

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification identical to the primary part. MSL 1 (Unlimited) rating ensures compatibility with standard storage and handling procedures across all options.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-074K3L replace RCS3216F432CS in automotive applications?

A: Yes. AC1206FR-074K3L meets all electrical and mechanical parameters of RCS3216F432CS and includes AEC-Q200 automotive qualification. Physical dimensions vary slightly (3.10mm length versus 3.20mm), but this remains within standard PCB design tolerances for 1206 package footprints.

Q: What is the difference between CRCW12064K30FKEA and RC1206FR-074K3L?

A: Both parts are electrically and mechanically equivalent. CRCW12064K30FKEA includes AEC-Q200 automotive certification; RC1206FR-074K3L does not. CRCW12064K30FKEA supports Cut Tape and Digi-Reel packaging; RC1206FR-074K3L is supplied in Tape & Reel format only. Selection depends on assembly equipment compatibility and application requirements.

Q: Why is ERJ-8ENF4301V marked "Not For New Designs"?

A: This designation indicates Panasonic has discontinued this part for new design applications. While functionally equivalent and currently in stock, new designs should specify AC1206FR-074K3L, CRCW12064K30FKEA, or RC1206FR-074K3L to ensure long-term supply continuity.

Q: Are physical dimension variations between substitutes significant?

A: Physical variations exist within the 1206 package specification. RCS3216F432CS and CRCW12064K30FKEA measure 3.20mm length; AC1206FR-074K3L and RC1206FR-074K3L measure 3.10mm length. Height variations range from 0.60mm to 0.70mm. These differences fall within standard 1206 footprint tolerances and do not require PCB redesign.

Q: Which substitute offers the best supply availability?

A: ERJ-8ENF4301V maintains the highest inventory (91758 pieces), followed by RC1206FR-074K3L (47340 pieces) and CRCW12064K30FKEA (35203 pieces). For active production designs, CRCW12064K30FKEA or AC1206FR-074K3L are recommended despite lower inventory, as both maintain active product status and automotive certification.

Q: Do all substitutes require identical soldering profiles?

A: All substitutes use identical 1206 package termination configuration (2 terminations) and thick film composition. Standard SMD soldering profiles for 1206 resistors apply uniformly across all listed parts. No process modifications are required.
