RCS3216F8661CS Equivalent & Substitute Parts

Part Overview

The RCS3216F8661CS is an 8.66 kOhms ±1% 0.25W chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design flexibility across multiple qualified suppliers is needed. All substitute parts listed maintain identical electrical specifications and mechanical compatibility with the RCS3216F8661CS.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F8661CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 8.66 kOhms (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 ~ 155°C (exact match required)

Mechanical 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 (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (exact match required)

All four substitute parts listed meet these criteria. Variations in physical dimensions (height, length, width) within the 1206 package specification, packaging format (Tape & Reel vs. bulk), and optional features (anti-sulfur coating, automotive AEC-Q200 qualification) do not affect substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CR1206-FX-8661ELF (Bourns Inc.) and RC1206FR-078K66L (YAGEO) are recommended as primary substitutes. Both parts carry Active product status, indicating ongoing manufacturer support and availability. CRCW12068K66FKEA (Vishay Dale) is also Active and includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability.

Secondary Substitute (Not For New Designs):

ERJ-8ENF8661V (Panasonic Electronic Components) carries a "Not For New Designs" product status. While electrically and mechanically equivalent, this part should be used only for replacement or maintenance of existing designs. New circuit designs should prioritize parts with Active status.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RCS3216F8661CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts are electrically and mechanically equivalent. They share identical resistance (8.66 kOhms), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Direct substitution is permissible without circuit modification.

Q: What is the difference between the anti-sulfur feature on the RCS3216F8661CS and the moisture-resistant feature on other substitutes?

A: Anti-sulfur coating on the RCS3216F8661CS provides additional protection against sulfur-containing environments. Moisture-resistant thick film composition on substitute parts addresses moisture ingress. Both approaches achieve MSL 1 (Unlimited) rating. Selection depends on environmental exposure requirements; anti-sulfur is preferred for high-sulfur environments, while standard moisture-resistant is suitable for typical industrial conditions.

Q: Are there packaging differences between the substitute parts?

A: All substitute parts are available in Tape & Reel (TR) packaging format. The RCS3216F8661CS packaging format is not specified in the provided data. Physical dimensions vary slightly within the 1206 specification: height ranges from 0.024" to 0.030" (0.60mm to 0.75mm). These variations are within standard 1206 package tolerances and do not affect PCB assembly compatibility.

Q: Should I use ERJ-8ENF8661V for new designs?

A: No. ERJ-8ENF8661V carries "Not For New Designs" status, indicating the manufacturer is discontinuing this product line. For new circuit designs, select from CR1206-FX-8661ELF, CRCW12068K66FKEA, or RC1206FR-078K66L, all of which have Active product status.

Q: What is the significance of AEC-Q200 qualification on CRCW12068K66FKEA and ERJ-8ENF8661V?

A: AEC-Q200 is an automotive industry qualification standard. Parts bearing this rating have undergone additional reliability testing for automotive applications. If your design requires automotive-grade components, CRCW12068K66FKEA is the recommended choice due to its Active status and AEC-Q200 qualification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, meeting EU Restriction of Hazardous Substances requirements. All are also REACH Unaffected, indicating no conflict with REACH chemical regulations.
