RC3216F8662CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F8662CS is a 86.6 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film, moisture-resistant component operates across -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status with 908 pieces available in inventory.

Substitute parts are identified when electrical specifications (resistance value, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical parameters (package type, dimensions, termination count) are identical or functionally equivalent. Alternative sources provide equivalent performance while maintaining compatibility with existing circuit designs.

Substitute Part Grouping Explanation

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

Electrical Equivalence Requirements:

Resistance value: 86.6 kOhms (exact match)
Tolerance: ±1% (exact match)
Power rating: 0.25W / 1/4W (exact match)
Temperature coefficient: ±100ppm/°C (exact match)
Operating temperature range: -55°C to 155°C (exact match)

Mechanical Equivalence Requirements:

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

Compliance Requirements:

RoHS3 compliance (required)
MSL 1 rating (required)
REACH unaffected status (required)

All identified substitute parts meet these criteria. Dimensional variations within the 1206 package specification (length 3.10-3.20mm, height 0.60-0.75mm) remain within standard tolerance and do not affect circuit compatibility.

Engineering Selection Recommendations

Direct Substitutes (Active Production):

CR1206-FX-8662ELF (Bourns Inc.) and RC1206FR-0786K6L (YAGEO) are direct functional equivalents in active production. Both maintain identical electrical specifications and ROHS3 compliance. Selection between these and the primary part depends on supply chain availability and packaging format requirements (Tape & Reel for both substitutes).

CRCW120686K6FKEA (Vishay Dale) is functionally equivalent with additional AEC-Q200 automotive qualification. This part is suitable for applications requiring automotive-grade reliability standards while maintaining all baseline electrical and mechanical specifications.

Alternative Source (Obsolescence Consideration):

ERJ-8ENF8662V (Panasonic Electronic Components) carries "Not For New Designs" status, indicating phase-out trajectory. This part remains electrically and mechanically equivalent but should not be selected for new circuit designs. Existing inventory may be used for legacy system maintenance only.

All substitute parts are ROHS3 compliant, MSL 1 rated, and REACH unaffected, matching the primary part's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-8662ELF replace RC3216F8662CS in existing designs?

A: Yes. Both parts share identical electrical specifications (86.6 kΩ ±1%, 0.25W, ±100ppm/°C, -55 to 155°C operating range) and mechanical package (1206). The 0.09mm height difference (0.75mm vs 0.66mm) remains within 1206 package tolerance and does not affect PCB assembly or circuit performance.

Q: What is the difference between the Bourns and YAGEO substitutes?

A: CR1206-FX-8662ELF (Bourns) and RC1206FR-0786K6L (YAGEO) are electrically identical. Physical dimensions vary slightly: Bourns measures 3.20mm length with 0.75mm maximum height; YAGEO measures 3.10mm length with 0.65mm maximum height. Both variations fall within 1206 package specification and are interchangeable.

Q: Why is CRCW120686K6FKEA listed as a similar rather than direct substitute?

A: CRCW120686K6FKEA includes AEC-Q200 automotive qualification, which is an additional feature beyond the baseline specification. Electrically and mechanically, it is fully equivalent. The "similar" designation reflects this additional qualification level rather than any functional difference.

Q: Should ERJ-8ENF8662V be used for new designs?

A: No. ERJ-8ENF8662V carries "Not For New Designs" status from Panasonic, indicating the product line is being phased out. Use CR1206-FX-8662ELF, RC1206FR-0786K6L, or CRCW120686K6FKEA for new circuit designs. ERJ-8ENF8662V inventory may be applied to legacy system repairs only.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status, matching the primary part's regulatory compliance profile.

Q: Does packaging format affect substitution eligibility?

A: Packaging format (Tape & Reel vs bulk) does not affect electrical or mechanical compatibility. The substitute parts listed are available in Tape & Reel format, which is standard for automated assembly. Component selection should be based on electrical equivalence and supply chain requirements rather than packaging format alone.
