Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F7873CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence: Resistance value (787 kOhms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must be identical.

Mechanical Compatibility: Package designation (0805/2012 Metric), physical dimensions (0.079" L × 0.049" W / 2.00mm × 1.25mm), and termination count (2) must match.

Environmental & Compliance: Operating temperature range (-55°C to 155°C), Moisture Sensitivity Level (MSL 1), RoHS3 compliance, and REACH status must be maintained.

Packaging Format: Tape & Reel (TR) format ensures compatibility with automated assembly processes.

All three identified substitute parts meet these criteria. Additional features such as automotive AEC-Q200 qualification or anti-sulfur characteristics represent functional enhancements that do not preclude substitution but may provide application-specific advantages.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified for direct replacement based on electrical and mechanical parameter equivalence. Selection among alternatives may be influenced by the following factors:

CRCW0805787KFKEA (Vishay Dale): Carries AEC-Q200 automotive qualification and demonstrates the lowest seated height (0.020" / 0.50mm), which may provide advantages in space-constrained PCB layouts. Inventory availability is substantial at 15,585 pieces.

ERJ-6ENF7873V (Panasonic): Also carries AEC-Q200 automotive qualification. Seated height is 0.028" (0.70mm), representing the maximum among substitute options. Inventory level is 6,937 pieces.

RC0805FR-07787KL (YAGEO): Features moisture-resistant characteristics aligned with the original component. Seated height is 0.024" (0.60mm). Inventory availability is 17,844 pieces, the highest among all options.

All parts maintain identical electrical performance, operating temperature range, and compliance certifications. Seated height variations remain within acceptable tolerances for standard PCB assembly processes. Product status is Active for all candidates, ensuring continued availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805787KFKEA replace RCS2012F7873CS in any application?

A: Yes. Both components share identical resistance value (787 kOhms), tolerance (±1%), power rating (0.125W), package type (0805), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Electrical and mechanical compatibility is complete.

Q: What is the significance of AEC-Q200 qualification on substitute parts?

A: AEC-Q200 is an automotive industry qualification standard. CRCW0805787KFKEA and ERJ-6ENF7873V carry this certification, indicating compliance with automotive reliability and performance requirements. The original RCS2012F7873CS does not list this qualification. Presence of AEC-Q200 does not prevent substitution but indicates enhanced qualification for automotive applications.

Q: Are there differences in seated height among the substitute parts?

A: Yes. Seated heights vary: RCS2012F7873CS (0.026" / 0.66mm), CRCW0805787KFKEA (0.020" / 0.50mm), ERJ-6ENF7873V (0.028" / 0.70mm), and RC0805FR-07787KL (0.024" / 0.60mm). These variations remain within standard PCB assembly tolerances and do not affect electrical performance or mechanical fit in standard 0805 footprints.

Q: Does the anti-sulfur feature of RCS2012F7873CS require a specific substitute?

A: No. Anti-sulfur characteristics are manufacturing enhancements that do not establish substitution requirements. RC0805FR-07787KL includes moisture-resistant features comparable to the original. All substitutes maintain MSL 1 rating, indicating unlimited moisture sensitivity protection.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All identified substitutes are supplied in Tape & Reel (TR) format, ensuring compatibility with automated assembly equipment and processes.

Q: What is the inventory status of substitute parts?

A: RC0805FR-07787KL (YAGEO) has the highest inventory at 17,844 pieces. CRCW0805787KFKEA (Vishay Dale) has 15,585 pieces. ERJ-6ENF7873V (Panasonic) has 6,937 pieces. All inventory levels indicate active production and availability.

Q: Do all parts comply with RoHS3 and REACH requirements?

A: Yes. All four components (original and substitutes) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
