RCS3216F35R7CS Equivalent & Substitute Parts

Part Overview

The RCS3216F35R7CS is a 35.7 Ohm ±1% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in 1206 (3216 Metric) package format. This component features anti-sulfur and moisture-resistant construction with a temperature coefficient of ±100ppm/°C and operating range of -55°C to 155°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and environmental ratings to ensure direct functional interchangeability in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F35R7CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value of 35.7 Ohms, tolerance of ±1%, and power rating of 0.25W (1/4W) must match exactly. Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C to 155°C establish thermal performance boundaries.

Mechanical Compatibility: Package format must be 1206 (3216 Metric) with two terminations. Physical dimensions and height specifications must accommodate the same PCB footprint and assembly processes.

Environmental & Compliance Requirements: All substitute parts must maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status. Composition must be thick film construction.

Allowed Variations: Substitute parts may differ in specific features (anti-sulfur vs. moisture-resistant only), automotive certifications (AEC-Q200), and product status (Active vs. Not For New Designs), provided all core electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status): CR1206-FX-35R7ELF (Bourns Inc.), CRCW120635R7FKEA (Vishay Dale), and RC1206FR-0735R7L (YAGEO) are all Active products with identical electrical specifications and full ROHS3 compliance. These parts are suitable for new designs and production applications.

CRCW120635R7FKEA Automotive Consideration: This Vishay Dale part includes AEC-Q200 automotive qualification, making it appropriate for automotive and high-reliability applications where enhanced qualification standards are required.

Secondary Substitute (Legacy Status): ERJ-8ENF35R7V (Panasonic Electronic Components) carries "Not For New Designs" status despite meeting all electrical and mechanical specifications. This part is suitable only for replacement or maintenance of existing assemblies and should not be selected for new product development.

Height Variation: All substitute parts exhibit minor height differences (0.024" to 0.030" seated height). These variations remain within typical PCB assembly tolerances and do not affect functional interchangeability in standard applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute RCS3216F35R7CS with any of the listed parts in new product designs?

A: Yes, CR1206-FX-35R7ELF, CRCW120635R7FKEA, and RC1206FR-0735R7L are all Active products suitable for new designs. ERJ-8ENF35R7V carries "Not For New Designs" status and should be used only for replacement applications.

Q: What determines if a part is a valid substitute?

A: Valid substitutes must match the resistance value (35.7 Ohms), tolerance (±1%), power rating (0.25W), package format (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1).

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

A: Yes. Seated height varies from 0.024" (CRCW120635R7FKEA) to 0.030" (CR1206-FX-35R7ELF). Length dimensions also vary slightly (0.122" to 0.126"). These variations are within standard PCB assembly tolerances and do not affect circuit functionality.

Q: What is the significance of AEC-Q200 rating on CRCW120635R7FKEA?

A: AEC-Q200 is an automotive qualification standard indicating enhanced reliability testing and quality assurance. This rating is relevant only if your application requires automotive-grade components. For non-automotive applications, this certification provides no additional functional benefit.

Q: Can I use ERJ-8ENF35R7V in production?

A: ERJ-8ENF35R7V is classified as "Not For New Designs," indicating Panasonic has discontinued active development and support for this part. It is suitable only for replacement or repair of existing assemblies. For new production, select from Active status alternatives.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All listed parts, including the main part RCS3216F35R7CS, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: What packaging formats are available for these substitutes?

A: All substitute parts are supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The main part RCS3216F35R7CS packaging format is not specified in the provided data.
