RCS3216F63R4CS Equivalent & Substitute Parts

Part Overview

The RCS3216F63R4CS is a 63.4 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 a temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent substitute parts are necessary for supply chain continuity, design flexibility, and sourcing optimization when the primary part becomes unavailable or when specific application requirements necessitate alternative manufacturer specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F63R4CS is determined by strict equivalence across the following critical parameters: resistance value (63.4 Ohms), tolerance (±1%), power rating (0.25W), package type (1206/3216 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All identified substitute parts meet these core electrical and mechanical specifications. Physical dimensions may vary within acceptable tolerances for the 1206 package standard. Compliance certifications (ROHS3, REACH Unaffected, EAR99) are maintained across all substitutes. Packaging format (Tape & Reel) and moisture sensitivity level (MSL 1) are consistent with the primary part. Substitution does not require design modification or re-qualification when these parameters are matched.

Parameter Comparison

Engineering Selection Recommendations

CRCW120663R4FKEA (Vishay Dale): This substitute is recommended as the primary alternative. It maintains active product status, full ROHS3 compliance, and includes automotive AEC-Q200 qualification. Physical dimensions are identical to the primary part with a maximum seated height of 0.024" (0.60mm). Inventory availability is substantial at 16,066 pieces.

RC1206FR-0763R4L (YAGEO): This substitute is recommended as a secondary alternative. It maintains active product status and full ROHS3 compliance with moisture-resistant thick film composition matching the primary part. Physical dimensions are within 1206 package tolerance with a maximum seated height of 0.026" (0.65mm). Inventory availability is high at 41,127 pieces.

ERJ-8ENF63R4V (Panasonic Electronic Components): This substitute is not recommended for new designs due to its "Not For New Designs" product status. However, it remains electrically and mechanically equivalent with automotive AEC-Q200 qualification and high inventory availability at 50,849 pieces. Use only for legacy system maintenance or existing design continuity where no alternative exists.

Frequently Asked Questions (FAQ)

Q: Can CRCW120663R4FKEA be used as a direct replacement for RCS3216F63R4CS?

A: Yes. Both parts share identical electrical specifications (63.4 Ohms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C), package type (1206/3216 Metric), composition (thick film), and compliance certifications (ROHS3, MSL 1). Physical dimensions are equivalent. No design modification is required.

Q: What is the difference between the Samsung RCS3216F63R4CS and Vishay CRCW120663R4FKEA?

A: The primary difference is manufacturer and feature set. The Vishay part includes automotive AEC-Q200 qualification, while the Samsung part features anti-sulfur properties. Both meet identical electrical and thermal specifications. The Vishay part has a slightly lower maximum seated height (0.024" vs 0.026").

Q: Why is the Panasonic ERJ-8ENF63R4V marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has discontinued active development of this product line. While the part remains electrically and mechanically equivalent and is currently in stock, it should not be selected for new circuit designs. Use existing inventory only for legacy system support or replacement applications.

Q: Are there any package compatibility issues between these substitutes?

A: No. All substitutes use the 1206 (3216 Metric) package with identical length (0.126" or 3.20mm) and width (0.063" or 1.60mm). Maximum seated heights vary slightly (0.024" to 0.028"), but all fall within standard 1206 package tolerances and are compatible with standard PCB footprints.

Q: Do all substitutes meet the same compliance requirements?

A: Yes. All four parts (primary and three substitutes) are ROHS3 compliant, REACH Unaffected, and classified as EAR99. All carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications are equivalent across all options.

Q: Can I mix different manufacturers in the same circuit board assembly?

A: Yes. All parts meet identical electrical specifications, package requirements, and compliance standards. Mixing manufacturers in the same assembly is acceptable from an engineering standpoint. However, verify with your procurement and quality assurance processes for any internal sourcing policies.
