Equivalent & Substitute Parts for RCS3216F6652CS

Part Overview

The RCS3216F6652CS is a 66.5 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, with an operating temperature range of -55°C to 155°C. The part is currently active in production with 649 pieces in stock inventory.

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component. This ensures functional interchangeability in circuit applications without performance degradation.

Substitute Part Grouping Explanation

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

Resistance Value: 66.5 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Power Rating: 0.25W / 1/4W (exact match required)
Package: 1206 (3216 Metric) (exact match required)
Composition: Thick Film (exact match required)
Temperature Coefficient: ±100ppm/°C (exact match required)
Operating Temperature: -55°C ~ 155°C (exact match required)
Compliance: ROHS3 Compliant, MSL 1 (Unlimited)

All four substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in feature sets (automotive AEC-Q200 certification, anti-sulfur properties) do not affect electrical interchangeability.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status)

AC1206FR-0766K5L, CRCW120666K5FKEA, and RC1206FR-0766K5L are all active products with full production support. These three parts are electrically and mechanically equivalent to the RCS3216F6652CS and are suitable for new designs and production applications.

AC1206FR-0766K5L and CRCW120666K5FKEA include automotive AEC-Q200 certification, which provides additional qualification for automotive applications. RC1206FR-0766K5L does not carry automotive certification but maintains all core electrical specifications.

Secondary Substitute (Legacy Status)

ERJ-8ENF6652V is marked as "Not For New Designs" by Panasonic Electronic Components. While electrically and mechanically equivalent, this part should be used only for legacy system maintenance or repair applications where the original part number is required for continuity. New designs should not incorporate this part number.

Compliance Verification

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-0766K5L replace RCS3216F6652CS in a new design?

A: Yes. AC1206FR-0766K5L meets all electrical and mechanical specifications of RCS3216F6652CS. Both are active products with identical resistance, tolerance, power rating, package, and operating temperature range. The addition of AEC-Q200 automotive certification in AC1206FR-0766K5L does not prevent its use in non-automotive applications.

Q: What is the difference between CRCW120666K5FKEA and RC1206FR-0766K5L?

A: Both parts are electrically identical 66.5 kOhms ±1% 0.25W 1206 resistors. CRCW120666K5FKEA includes AEC-Q200 automotive qualification; RC1206FR-0766K5L does not. Physical dimensions vary slightly within 1206 package tolerance (length 3.20mm vs 3.10mm, height 0.60mm vs 0.65mm). These dimensional variations do not affect circuit performance or PCB layout compatibility.

Q: Why is ERJ-8ENF6652V marked "Not For New Designs"?

A: Panasonic has designated this part as legacy. While functionally equivalent, the manufacturer recommends using current-generation alternatives for new product development. ERJ-8ENF6652V remains available for existing product support and repair applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RCS3216F6652CS and all four substitute parts (AC1206FR-0766K5L, CRCW120666K5FKEA, ERJ-8ENF6652V, RC1206FR-0766K5L) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I mix different substitute parts in the same production batch?

A: Yes. All substitute parts are electrically and mechanically interchangeable. However, design documentation should specify the approved part numbers to maintain traceability and ensure consistent sourcing from qualified suppliers.

Q: What is the significance of the 1206 (3216 Metric) package designation?

A: 1206 is the imperial designation; 3216 Metric is the metric equivalent. Both refer to the same physical package with dimensions of 3.20mm × 1.60mm (length × width). All listed parts use this identical package footprint and are PCB layout compatible.
