Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F46R4CS is determined by strict matching of the following critical parameters:

Electrical Specifications: Resistance value of 46.4 Ohms, tolerance of ±1%, and power rating of 0.25W (1/4W) must be identical across all substitute parts.

Package Compatibility: All substitute parts must use the 1206 (3216 Metric) surface mount package with two terminations to ensure mechanical fit and soldering compatibility on printed circuit boards.

Environmental Ratings: Operating temperature range of -55°C to 155°C and temperature coefficient of ±100ppm/°C must be maintained. RoHS3 compliance and MSL 1 rating are required for regulatory and manufacturing process compatibility.

Composition: Thick film construction is the specified technology for this application.

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the RCS3216F46R4CS in standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Designs: CR1206-FX-46R4ELF (Bourns Inc.), CRCW120646R4FKEA (Vishay Dale), and RC1206FR-0746R4L (YAGEO) are all suitable substitutes with active product status. These parts maintain full electrical and environmental specification equivalence to the RCS3216F46R4CS.

For Automotive Applications: CRCW120646R4FKEA (Vishay Dale) includes AEC-Q200 automotive qualification, providing additional reliability assurance for automotive circuit applications.

For Legacy or Existing Designs: ERJ-8ENF46R4V (Panasonic Electronic Components) is functionally equivalent but carries a "Not For New Designs" status. This part remains suitable for replacement in existing production runs or field service applications where the original part is unavailable.

Packaging Considerations: The RCS3216F46R4CS is supplied in bulk packaging, while all substitute parts are available in Tape & Reel (TR) format. Design and procurement teams should verify packaging compatibility with assembly equipment and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-46R4ELF be used as a direct replacement for RCS3216F46R4CS?

A: Yes. Both parts share identical electrical specifications (46.4 Ohms ±1%, 0.25W), package format (1206/3216 Metric), temperature range (-55°C to 155°C), and RoHS3 compliance. The CR1206-FX-46R4ELF is a direct functional equivalent.

Q: What is the difference between the substitute parts listed?

A: All substitute parts meet the core electrical and environmental requirements. The primary differences are manufacturer identity, product status (active versus not for new designs), and optional certifications. CRCW120646R4FKEA includes AEC-Q200 automotive qualification. ERJ-8ENF46R4V is marked "Not For New Designs" but remains functionally equivalent.

Q: Are there dimensional differences between the main part and substitutes?

A: All parts use the 1206 (3216 Metric) package with identical length (0.126" / 3.20mm) and width (0.063" / 1.60mm). Maximum seated heights vary slightly (0.026" to 0.030"), but these variations are within standard PCB assembly tolerances and do not affect interchangeability.

Q: Is the RCS3216F46R4CS anti-sulfur feature available in substitute parts?

A: The RCS3216F46R4CS specifically includes anti-sulfur construction. Substitute parts CR1206-FX-46R4ELF and RC1206FR-0746R4L specify moisture-resistant features. CRCW120646R4FKEA and ERJ-8ENF46R4V do not explicitly list anti-sulfur properties in the provided specifications. For applications requiring anti-sulfur protection, verify with the manufacturer or consider the RCS3216F46R4CS as the primary choice.

Q: Can ERJ-8ENF46R4V be used in new product designs?

A: ERJ-8ENF46R4V carries a "Not For New Designs" status, indicating the manufacturer recommends against its use in new development. It remains suitable for replacement in existing production or field service scenarios where supply of the original part is constrained.

Q: What packaging format should be selected for high-volume assembly?

A: Tape & Reel (TR) packaging is standard for automated surface mount assembly. CR1206-FX-46R4ELF, CRCW120646R4FKEA, ERJ-8ENF46R4V, and RC1206FR-0746R4L are all available in TR format. Bulk packaging (RCS3216F46R4CS) is typically used for manual assembly or low-volume applications.
