Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F4220CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 422 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Substitute parts are grouped into two categories based on additional features:

Category 1 - Direct Equivalent (Moisture Resistant): RC0805FR-07422RL (YAGEO) maintains identical electrical and mechanical specifications with moisture resistant composition matching the original part.

Category 2 - Automotive Grade Equivalents (AEC-Q200): CRCW0805422RFKEA (Vishay Dale), ERJ-6ENF4220V (Panasonic Electronic Components), and RMCF0805FT422R (Stackpole Electronics Inc) provide automotive-qualified alternatives with AEC-Q200 ratings while maintaining all core electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are Active product status components with ROHS3 compliance and MSL 1 rating, confirming long-term availability and regulatory compliance alignment with the RC2012F4220CS.

RC0805FR-07422RL (YAGEO) is the direct functional equivalent, maintaining moisture resistant composition identical to the original part. This substitute is suitable for applications where the original Samsung part specifications are required without automotive qualification.

CRCW0805422RFKEA (Vishay Dale), ERJ-6ENF4220V (Panasonic Electronic Components), and RMCF0805FT422R (Stackpole Electronics Inc) are automotive-grade alternatives with AEC-Q200 certification. These parts are appropriate for applications requiring automotive-qualified components or where supply chain diversification across automotive-grade suppliers is necessary. All three automotive alternatives maintain identical electrical parameters and operating temperature range while providing enhanced reliability qualification.

Height variation across substitute parts ranges from 0.020" to 0.028" (0.50mm to 0.70mm), which remains within typical PCB assembly tolerances for 0805 components. Packaging format differences (Cut Tape vs. Tape & Reel) do not affect electrical or mechanical compatibility and reflect supplier distribution preferences.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07422RL replace RC2012F4220CS in any application?

A: Yes. RC0805FR-07422RL meets all mandatory electrical and mechanical parameters: 422 Ohms ±1%, 0.125W power rating, 0805 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, and MSL 1 rating. Both parts are thick film composition with moisture resistant features.

Q: What is the difference between the automotive-grade substitutes and the direct equivalent?

A: CRCW0805422RFKEA, ERJ-6ENF4220V, and RMCF0805FT422R include AEC-Q200 automotive qualification certification. All five parts (including RC0805FR-07422RL) share identical core electrical specifications. The automotive-grade parts are suitable for applications requiring automotive reliability standards.

Q: Are there packaging format differences between these parts?

A: RC0805FR-07422RL is supplied in Cut Tape (CT) & Digi-Reel® format, while RC2012F4220CS, CRCW0805422RFKEA, ERJ-6ENF4220V, and RMCF0805FT422R are supplied in Tape & Reel (TR) format. Packaging format does not affect electrical or mechanical compatibility and reflects supplier distribution methods.

Q: Do height differences affect PCB assembly compatibility?

A: Height variation ranges from 0.020" (0.50mm) to 0.028" (0.70mm) across all parts. This variation is within standard PCB assembly tolerances for 0805 components and does not affect reflow soldering or component placement compatibility.

Q: Which substitute part has the highest inventory availability?

A: RC0805FR-07422RL (YAGEO) has 122,854 pieces in stock, providing the highest inventory level among all substitute options.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts—RC0805FR-07422RL, CRCW0805422RFKEA, ERJ-6ENF4220V, and RMCF0805FT422R—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original RC2012F4220CS specifications.
