Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW1206845RFKEA (Vishay Dale) and RC1206FR-07845RL (YAGEO) are recommended as primary substitutes. Both parts maintain Active product status, ensuring long-term availability and continued manufacturing support. CRCW1206845RFKEA includes AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability. RC1206FR-07845RL provides moisture-resistant characteristics aligned with the original part specification.

Secondary Substitute (Legacy Applications):

ERJ-8ENF8450V (Panasonic) is classified as Not For New Designs. This part is suitable only for replacement or repair of existing assemblies where the original part number is unavailable. New circuit designs should not incorporate this part number.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard PCB assembly processes and storage requirements. No additional handling or storage modifications are required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206845RFKEA replace RCS3216F8450CS in all applications?

A: Yes. Both parts share identical electrical specifications (845 Ohms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C), package type (1206), and compliance ratings (ROHS3, MSL 1). The CRCW1206845RFKEA includes additional AEC-Q200 automotive qualification, making it suitable for automotive and industrial applications.

Q: What is the difference between RC1206FR-07845RL and RCS3216F8450CS?

A: Both parts are electrically and mechanically equivalent with matching resistance, tolerance, power rating, temperature coefficient, and operating range. The primary difference is manufacturer (YAGEO vs. Samsung Electro-Mechanics). Physical dimensions vary slightly: RC1206FR-07845RL measures 0.122" L x 0.063" W (3.10mm x 1.60mm) compared to RCS3216F8450CS at 0.126" L x 0.063" W (3.20mm x 1.60mm). Both dimensions are within 1206 package specifications.

Q: Why is ERJ-8ENF8450V marked as Not For New Designs?

A: ERJ-8ENF8450V is classified as Not For New Designs by Panasonic, indicating the manufacturer is phasing out this product line. While the part meets all electrical and mechanical requirements for substitution, new circuit designs should specify CRCW1206845RFKEA or RC1206FR-07845RL to ensure long-term component availability.

Q: Are there packaging differences between these substitute parts?

A: All substitute parts are supplied in Tape & Reel (TR) packaging format. The RCS3216F8450CS original part does not specify packaging format in the provided data. Tape & Reel packaging is standard for automated PCB assembly processes and is compatible with standard pick-and-place equipment.

Q: Do these parts require different PCB footprints?

A: No. All parts use the 1206 (3216 Metric) package with identical footprint specifications. Physical dimension variations (height range 0.024" to 0.028") fall within standard 1206 package tolerances and do not require PCB layout modifications.

Q: What is the inventory status for substitute parts?

A: CRCW1206845RFKEA has 25,565 pieces in stock, ERJ-8ENF8450V has 31,745 pieces in stock, and RC1206FR-07845RL has 28,394 pieces in stock. All substitute parts maintain substantial inventory levels for immediate availability.
