Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (402 kOhms), tolerance (±1%), power rating (0.125W), package format (0805 / 2012 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and regulatory compliance (ROHS3, REACH Unaffected, EAR99). All identified substitute parts meet these core electrical and mechanical criteria. Variations in physical dimensions (height-seated maximum) and packaging format (Tape & Reel versus Cut Tape) do not affect functional substitution but may impact assembly and procurement workflows. Product status transitions (Active versus Discontinued) are noted for supply chain planning.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical equivalence to the RC2012F4023CS across resistance, tolerance, power rating, package dimensions, and temperature specifications. Selection between substitute options depends on application-specific requirements:

For general industrial applications: CR0805-FX-4023ELF (Bourns) and RC0805FR-07402KL (YAGEO) provide moisture-resistant characteristics matching the original Samsung component, with Active product status and established supply availability.

For automotive applications: ERJ-6ENF4023V (Panasonic), KTR10EZPF4023 (Rohm), RMCF0805FT402K (Stackpole), and CRCW0805402KFKEA (Vishay Dale) carry AEC-Q200 automotive qualification. KTR10EZPF4023 includes high-voltage rating designation. All automotive-qualified options maintain Active product status.

For space-constrained PCB layouts: CRCW0805402KFKEA (Vishay Dale) offers the lowest seated height at 0.020" (0.50mm), while ERJ-6ENF4023V (Panasonic) presents the maximum seated height at 0.028" (0.70mm). Height variations remain within standard 0805 package tolerances.

For supply chain continuity: MCR10ERTF4023 (Rohm) is marked Discontinued at DiGi Electronics and should not be selected for new designs requiring long-term availability. All other listed parts maintain Active status.

All substitute parts comply with ROHS3, REACH Unaffected, and EAR99 classifications, matching the regulatory profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can CR0805-FX-4023ELF replace RC2012F4023CS in a moisture-sensitive application?

A: Yes. Both components carry MSL 1 (Unlimited) moisture sensitivity rating and feature moisture-resistant thick film composition. Electrical specifications, package format, and operating temperature ranges are identical.

Q: What is the difference between automotive-qualified and non-automotive substitute parts?

A: Automotive-qualified parts (ERJ-6ENF4023V, KTR10EZPF4023, RMCF0805FT402K, CRCW0805402KFKEA) carry AEC-Q200 certification, indicating compliance with automotive reliability and environmental stress testing standards. Non-automotive parts (CR0805-FX-4023ELF, RC0805FR-07402KL) do not carry this certification. Selection depends on end-application requirements.

Q: Is MCR10ERTF4023 suitable for new product designs?

A: MCR10ERTF4023 is marked Discontinued at DiGi Electronics. For new designs requiring long-term component availability and supply chain stability, select from Active-status alternatives.

Q: Do height differences between substitute parts affect PCB assembly?

A: Height variations range from 0.020" (0.50mm) to 0.028" (0.70mm) across all listed parts. These differences remain within standard 0805 package tolerances and do not affect standard reflow soldering processes or PCB clearance requirements. Verify specific PCB design constraints if height-critical applications exist.

Q: Can I substitute a Tape & Reel packaged part with a Cut Tape packaged part?

A: Both packaging formats contain identical components. Substitution is functionally valid. However, Cut Tape & Digi-Reel® packaging (MCR10ERTF4023) may require different handling and feeder compatibility in automated assembly equipment compared to standard Tape & Reel format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status and REACH Unaffected classification, matching the regulatory compliance of RC2012F4023CS.
