Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F6810CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (681 Ohms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must match exactly. These parameters define the functional performance in circuit operation.

Mechanical Parameters: Package designation (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), and number of terminations (2) must be identical to ensure PCB footprint compatibility and assembly process compatibility.

Environmental & Compliance Parameters: Operating temperature range (-55°C to 155°C), Moisture Sensitivity Level (MSL 1), RoHS compliance status, and REACH status determine suitability for specific application environments and regulatory requirements.

All substitute parts listed below satisfy these criteria. Variations in packaging format (Cut Tape vs. Tape & Reel), seated height tolerances, and optional certifications (such as AEC-Q200 automotive qualification) do not affect functional interchangeability but may influence procurement and application context.

Engineering Selection Recommendations

Primary Selection Criteria:

All listed substitute parts maintain full electrical and mechanical equivalence to the RC2012F6810CS. Selection among alternatives should be based on the following factors:

RoHS Compliance: The CRCW0805681RFKTA variant is RoHS non-compliant and REACH Affected. This part is suitable only for applications where regulatory exemptions apply or legacy system maintenance is required. For new designs and applications subject to RoHS3 requirements, select from the remaining eight alternatives, all of which are ROHS3 Compliant and REACH Unaffected.

Packaging Format: Choose between Cut Tape (CT) format for manual or small-batch assembly operations, or Tape & Reel (TR) format for automated high-volume production. The main part RC2012F6810CS is supplied in Cut Tape format. Equivalent Cut Tape options include CR0805-FX-6810ELF (Bourns), RMCF0805FG681R (Stackpole), and ERJ-6ENF6810V (Panasonic). Tape & Reel alternatives are available from all manufacturers.

Automotive Applications: Parts bearing AEC-Q200 certification are qualified for automotive use. These include ERJ-6ENF6810V (Panasonic), KTR10EZPF6810 (Rohm), RMCF0805FG681R and RMCF0805FT681R (Stackpole), and both CRCW variants (Vishay Dale). Non-automotive applications may select from any compliant alternative.

Inventory Availability: Substitute parts with highest inventory levels include RC0805FR-07681RL (YAGEO, 221,715 pcs), RMCF0805FG681R (Stackpole, 187,330 pcs), and RMCF0805FT681R (Stackpole, 133,662 pcs).

Product Status: All listed parts maintain Active product status, ensuring continued availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC2012F6810CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts are electrically and mechanically equivalent. They share identical resistance value (681 Ohms), tolerance (±1%), power rating (0.125W), package designation (0805), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Direct substitution on the PCB is possible without circuit modification.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging supplies individual components on a carrier tape, suitable for manual assembly, prototyping, and small production runs. Tape & Reel (TR) packaging supplies components on a continuous reel compatible with automated pick-and-place assembly equipment, optimized for high-volume manufacturing. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Does the seated height variation (0.50mm to 0.70mm) affect PCB compatibility?

A: No. All seated height values fall within standard 0805 package tolerances and do not affect PCB footprint compatibility or assembly clearance. Height variation is a manufacturing tolerance characteristic and does not impact electrical performance or mechanical fit.

Q: Why should I avoid CRCW0805681RFKTA for new designs?

A: The CRCW0805681RFKTA variant is RoHS non-compliant and REACH Affected. Regulatory requirements in most markets mandate RoHS3 compliance for new component designs. This part is restricted to legacy system maintenance or applications with documented regulatory exemptions. For all new designs, select from the eight RoHS3-compliant alternatives.

Q: Are AEC-Q200 certified parts required for my application?

A: AEC-Q200 certification is required only for automotive applications subject to automotive industry standards. Non-automotive applications do not require this certification. If your application is non-automotive, any RoHS3-compliant substitute part is suitable. If your application is automotive, select from ERJ-6ENF6810V, KTR10EZPF6810, RMCF0805FG681R, RMCF0805FT681R, CRCW0805681RFKEA, or CRCW0805681RFKTA.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. Components with MSL 1 have unlimited shelf life and do not require special moisture-controlled storage or handling procedures. All listed parts share this specification, ensuring consistent storage and handling requirements across all alternatives.

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

A: Yes. All substitute parts are functionally equivalent and can be used interchangeably within the same circuit or production batch. However, for traceability and quality control purposes, many manufacturers prefer to maintain consistent part sourcing within a single production run.
