Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified based on strict equivalence of the following critical parameters:

Mandatory Equivalence Criteria:

• Resistance value: 681 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL 1 rating

Substitution Categories:

Direct Substitutes (Functionally Identical): Parts meeting all mandatory criteria with identical or compatible physical dimensions and electrical performance.

Application-Specific Alternatives: Parts meeting all mandatory criteria but with additional certifications (AEC-Q200 automotive qualification) or enhanced features (moisture resistance) suitable for specialized applications.

Packaging Variants: Parts with identical electrical specifications but different packaging formats (Tape & Reel vs. Cut Tape & Digi-Reel) to accommodate procurement and assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Continuity: RC1206FR-07681RL (YAGEO) and RMCF1206FT681R (Stackpole Electronics Inc) are recommended as primary substitutes. Both maintain Active product status, meet all electrical and environmental specifications, and are available in high inventory quantities (522,628 pcs and 43,097 pcs respectively). These parts provide direct functional equivalence with established supply chain reliability.

For Automotive Applications: RMCF1206FT681R (Stackpole Electronics Inc), AC1206FR-07681RL (YAGEO), and CRCW1206681RFKEA (Vishay Dale) include AEC-Q200 automotive qualification. These parts are suitable for automotive-grade circuit designs requiring enhanced reliability and qualification documentation. All three maintain Active product status.

For Enhanced Moisture Resistance: AC1206FR-07681RL (YAGEO) combines both Automotive AEC-Q200 certification and explicit moisture-resistant features, providing the highest level of environmental protection among available substitutes.

For Packaging Flexibility: CRCW1206681RFKEA (Vishay Dale) is available in Cut Tape & Digi-Reel packaging, accommodating assembly operations that require alternative packaging formats to standard Tape & Reel.

Parts to Avoid for New Designs: ERJ-8ENF6810V (Panasonic Electronic Components) carries "Not For New Designs" product status. While electrically equivalent and AEC-Q200 qualified, this part should not be selected for new circuit designs due to manufacturer discontinuation trajectory.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC3216F6810CS with any of the listed equivalent parts without circuit redesign?

A: Yes. All listed substitute parts meet identical electrical specifications (681Ω ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C operating range) and are packaged in the 1206 (3216 Metric) form factor. Direct PCB footprint compatibility is maintained. No circuit redesign is required.

Q: What is the difference between "Direct Substitutes" and "Application-Specific Alternatives"?

A: Direct substitutes (CR1206-FX-6810ELF, RC1206FR-07681RL) provide identical functionality for general industrial applications. Application-specific alternatives (RMCF1206FT681R, AC1206FR-07681RL, CRCW1206681RFKEA) include AEC-Q200 automotive qualification, making them suitable for automotive circuit designs where enhanced reliability documentation and qualification testing are required.

Q: Does the packaging type (Tape & Reel vs. Cut Tape & Digi-Reel) affect electrical performance?

A: No. Packaging type affects only procurement, handling, and assembly logistics. Electrical performance, thermal characteristics, and reliability are identical regardless of packaging format. Selection should be based on assembly equipment compatibility and supply chain requirements.

Q: Why is ERJ-8ENF6810V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) is transitioning this product line toward discontinuation. While the part remains functionally equivalent and AEC-Q200 qualified, it should not be selected for new circuit designs to avoid future supply chain disruption. Active alternatives are available from other manufacturers.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification, matching the regulatory status of the RC3216F6810CS. All parts are also REACH Unaffected and classified under ECCN EAR99.

Q: What is MSL 1 (Unlimited) and why is it important?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake-out requirements. All listed parts maintain MSL 1 rating, meaning standard storage conditions are sufficient without special humidity control or pre-reflow baking procedures.

Q: Can I use CRCW1206681RFKEA in high-volume production with automated assembly?

A: Yes. CRCW1206681RFKEA is available in Cut Tape & Digi-Reel packaging, which is compatible with standard pick-and-place assembly equipment. Verify your assembly system specifications for tape format compatibility before production implementation.

Q: Which substitute offers the best environmental performance?

A: AC1206FR-07681RL (YAGEO) provides the most comprehensive environmental specification, combining Automotive AEC-Q200 qualification with explicit moisture-resistant features. This part is suitable for applications requiring maximum environmental protection and automotive-grade reliability.
