RCS3216F4643CS Equivalent & Substitute Parts

Part Overview

The RCS3216F4643CS is a 464 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 and carries MSL 1 (Unlimited) moisture sensitivity rating. With active product status and 674 pieces in stock, this part serves as a reference for identifying functionally equivalent alternatives from other manufacturers that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS3216F4643CS is determined by strict equivalence across the following parameters: resistance value (464 kOhms), tolerance (±1%), power rating (0.25W), package type (1206 / 3216 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (RoHS3, REACH Unaffected). All identified substitute parts match these core electrical and mechanical specifications. Variations in physical dimensions (length, width, height) and packaging format (Tape & Reel versus bulk) do not affect functional substitutability when the above parameters are identical. Product status and specific feature sets (automotive qualification, anti-sulfur properties) are noted but do not prevent substitution at the functional level.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—CRCW1206464KFKEA (Vishay Dale), ERJ-8ENF4643V (Panasonic), and RC1206FR-07464KL (YAGEO)—satisfy the core electrical and mechanical requirements for direct substitution with the RCS3216F4643CS.

CRCW1206464KFKEA carries automotive AEC-Q200 qualification and maintains active product status, making it suitable for applications requiring automotive-grade components. Inventory availability is 13,793 pieces.

ERJ-8ENF4643V also carries automotive AEC-Q200 qualification but is designated "Not For New Designs," indicating this part is in mature or end-of-life phase. This designation should be considered for long-term supply chain planning. Inventory availability is 54,012 pieces.

RC1206FR-07464KL maintains active product status without automotive qualification. It features moisture-resistant properties similar to the main part. Inventory availability is 11,528 pieces.

For new designs, CRCW1206464KFKEA or RC1206FR-07464KL are preferred due to active product status. For existing designs or automotive applications, CRCW1206464KFKEA is the optimal choice.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206464KFKEA replace RCS3216F4643CS in any application?

A: Yes. Both parts share identical resistance (464 kOhms), tolerance (±1%), power rating (0.25W), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (RoHS3, REACH Unaffected). Physical dimension variations (height: 0.026" vs 0.024") do not affect functional compatibility in standard PCB assembly.

Q: Why is ERJ-8ENF4643V marked "Not For New Designs"?

A: This designation indicates the part is in mature production phase and may have limited future availability. While functionally equivalent and currently in stock (54,012 pieces), it should not be selected for new product designs requiring long-term component supply assurance.

Q: Are there packaging differences between these substitutes?

A: All substitutes are supplied in Tape & Reel (TR) format. The main part RCS3216F4643CS uses standard packaging notation (-). This difference affects handling and assembly processes but does not impact electrical or mechanical performance.

Q: Do the automotive AEC-Q200 qualifications of CRCW1206464KFKEA and ERJ-8ENF4643V affect non-automotive applications?

A: No. AEC-Q200 qualification represents additional testing and quality assurance beyond standard requirements. These parts are fully compatible with non-automotive applications and offer enhanced reliability margins.

Q: What is the significance of the height differences (0.026" vs 0.024" vs 0.028")?

A: These minor variations (0.66mm, 0.60mm, 0.70mm) fall within standard PCB assembly tolerances and do not affect board-level compatibility. All parts conform to 1206 package specifications.

Q: Can I mix these substitute parts within the same production batch?

A: Yes. All parts meet identical electrical specifications and package requirements. However, for traceability and quality control purposes, maintaining consistent part sourcing within a single production run is recommended.
