Equivalent & Substitute Parts for RCS3216F8660CS

Part Overview

The RCS3216F8660CS is a 866 Ohm ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status with anti-sulfur and moisture-resistant properties. The part is ROHS3 compliant and operates across the temperature range of -55°C to 155°C.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design specifications allow for functionally equivalent alternatives from qualified manufacturers. All substitute parts listed maintain identical electrical specifications and package dimensions within acceptable tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F8660CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 866 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)

Physical & Package Specifications:

• Package type: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance & Environmental:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All four substitute parts listed meet these criteria. Variations in physical dimensions (length, width, height) within manufacturer tolerances and differences in optional features (such as automotive AEC-Q200 certification) do not disqualify substitution eligibility.

Engineering Selection Recommendations

Primary Selection (Active Status):

For new designs and ongoing production, select from parts with Active product status:

• AC1206FR-07866RL (YAGEO): Active status with automotive AEC-Q200 qualification. Suitable for automotive and industrial applications requiring enhanced reliability standards.
• CRCW1206866RFKEA (Vishay Dale): Active status with automotive AEC-Q200 qualification. Highest inventory availability (4783 pcs). Recommended for high-volume production.
• RC1206FR-07866RL (YAGEO): Active status without automotive qualification. Suitable for general industrial and consumer applications.

Secondary Selection (Legacy Applications):

• ERJ-8ENF8660V (Panasonic): Designated as Not For New Designs. Use only for replacement in existing equipment or legacy system maintenance. Highest inventory availability (60309 pcs) indicates established supply for support applications.

Compliance Verification:

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

Frequently Asked Questions (FAQ)

Q1: Can I substitute RCS3216F8660CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts are electrically and mechanically equivalent. They share identical resistance (866 Ohms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and package type (1206). Direct substitution is permissible at the component level.

Q2: What is the difference between parts with and without AEC-Q200 certification?

A: AEC-Q200 certification indicates automotive-grade qualification with enhanced reliability testing and traceability requirements. AC1206FR-07866RL and CRCW1206866RFKEA include this certification. RC1206FR-07866RL does not. For automotive applications, select AEC-Q200 qualified parts. For non-automotive applications, both certified and non-certified parts are functionally equivalent.

Q3: Why is ERJ-8ENF8660V marked as "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends against use in new product designs. However, the part remains functionally equivalent and is suitable for replacement in existing equipment or legacy system support.

Q4: Are there physical dimension differences between substitute parts?

A: Minor variations exist within manufacturer tolerances. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm). Height ranges from 0.024" to 0.028" (0.60mm to 0.70mm). These variations are within standard PCB assembly tolerances and do not affect functionality or board layout compatibility for 1206 package footprints.

Q5: Which substitute part should I select for maximum inventory availability?

A: CRCW1206866RFKEA (Vishay Dale) offers the highest inventory level at 4783 pcs. For legacy support applications, ERJ-8ENF8660V (Panasonic) has 60309 pcs available.

Q6: Are all substitute parts suitable for high-temperature applications?

A: Yes. All parts, including the primary RCS3216F8660CS, operate across the identical temperature range of -55°C to 155°C with ±100ppm/°C temperature coefficient. Selection between parts should be based on product status, availability, and certification requirements rather than thermal performance.
