Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC2012F434CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (430 kOhms), tolerance (±1%), and power rating (0.125W) must be identical across all substitute parts.

Physical Parameters: Package designation (0805 / 2012 Metric) and termination count (2) must match exactly to ensure PCB footprint compatibility and assembly process compatibility.

Environmental Parameters: Operating temperature range (-55°C ~ 155°C) and temperature coefficient (±100ppm/°C) must be maintained for circuit performance consistency.

Regulatory Parameters: All substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory equivalence.

Composition: Thick film construction is consistent across all substitute parts.

Substitute parts are grouped into two categories: Direct equivalents (identical specifications including moisture resistant features) and similar parts (meeting all electrical and mechanical parameters with additional automotive AEC-Q200 certification).

Parameter Comparison

Engineering Selection Recommendations

All five parts listed maintain identical electrical specifications (430 kOhms ±1%, 0.125W) and mechanical compatibility (0805 package, 2-termination configuration). All parts are Active product status with ROHS3 compliance and REACH Unaffected designation.

RC0805FR-07430KL (YAGEO) provides direct functional equivalence with identical moisture resistant thick film construction. This part is available in alternative packaging (Cut Tape & Digi-Reel®) and demonstrates the lowest seated height (0.024" / 0.60mm), which may be advantageous for space-constrained PCB layouts.

CRCW0805430KFKEA (Vishay Dale), ERJ-6ENF4303V (Panasonic), and RMCF0805FT430K (Stackpole) provide functional equivalence with additional automotive AEC-Q200 certification. These parts are suitable for applications requiring automotive-grade component qualification. Seated height variations range from 0.020" to 0.028", with CRCW0805430KFKEA offering the most compact profile (0.020" / 0.50mm).

Selection between substitute parts should be based on packaging format requirements (Tape & Reel versus Cut Tape), PCB assembly equipment compatibility, and whether automotive AEC-Q200 certification is required for the application.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07430KL replace RC2012F434CS in all applications?

A: Yes. Both parts share identical electrical parameters (430 kOhms ±1%, 0.125W), operating temperature range (-55°C ~ 155°C), temperature coefficient (±100ppm/°C), and package designation (0805 / 2012 Metric). The primary difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and seated height (0.024" versus 0.026"), which do not affect functional compatibility.

Q: What is the difference between the Samsung RC2012F434CS and the automotive-qualified alternatives?

A: The Samsung RC2012F434CS does not specify automotive AEC-Q200 certification. The CRCW0805430KFKEA (Vishay Dale), ERJ-6ENF4303V (Panasonic), and RMCF0805FT430K (Stackpole) all carry AEC-Q200 certification, indicating qualification for automotive applications. All parts maintain identical core electrical and mechanical specifications.

Q: Are there physical footprint differences between these substitute parts?

A: All parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Seated height varies slightly: RC0805FR-07430KL (0.024" / 0.60mm), CRCW0805430KFKEA (0.020" / 0.50mm), ERJ-6ENF4303V (0.028" / 0.70mm), RMCF0805FT430K (0.026" / 0.65mm), and RC2012F434CS (0.026" / 0.66mm). These variations are within typical PCB assembly tolerances and do not affect standard footprint compatibility.

Q: Which substitute part has the best availability?

A: ERJ-6ENF4303V (Panasonic) shows the highest inventory level at 52,757 pieces. RC0805FR-07430KL (YAGEO) has 41,295 pieces in stock. CRCW0805430KFKEA (Vishay Dale) has 23,914 pieces. RMCF0805FT430K (Stackpole) has 11,796 pieces. RC2012F434CS (Samsung) has 797 pieces in stock.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. All five parts are ROHS3 compliant and REACH Unaffected, ensuring equivalent regulatory compliance for both consumer and industrial applications.

Q: What packaging options are available?

A: RC2012F434CS, CRCW0805430KFKEA, ERJ-6ENF4303V, and RMCF0805FT430K are supplied in Tape & Reel (TR) format. RC0805FR-07430KL is available in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly equipment compatibility and procurement requirements.
