RC2012F4223CS 422kΩ ±1% 1/8W 0805 Chip Resistor Equivalent & Substitute Parts

Part Overview

The RC2012F4223CS is a 422 kOhms ±1% 0.125W thick film chip resistor in 0805 (2012 Metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status with RoHS3 compliance and MSL Level 1 rating. Substitute parts are identified when original inventory becomes unavailable, when supply chain optimization is required, or when design specifications permit equivalent performance from alternative manufacturers while maintaining identical electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F4223CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 422 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

• Package designation: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match):

• RoHS3 Compliant
• MSL Level 1 (Unlimited)
• REACH Unaffected
• ECCN: EAR99

All substitute parts listed below meet these criteria across all manufacturers. Variations in seated height (ranging from 0.020" to 0.028") remain within acceptable PCB assembly tolerances and do not affect electrical performance or interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred for General Applications): RC0805FR-07422KL (YAGEO) is the primary direct substitute. This part maintains identical electrical specifications and moisture-resistant thick film composition. YAGEO RC_L series components are widely available with 128,215 pieces in current inventory, ensuring supply continuity. Seated height of 0.024" (0.60mm) is within standard PCB assembly tolerances.

Automotive-Qualified Alternatives (For AEC-Q200 Applications): Three substitute parts carry AEC-Q200 automotive qualification:

• CRCW0805422KFKEA (Vishay Dale): Lowest seated height at 0.020" (0.50mm), suitable for high-density PCB layouts
• ERJ-6ENF4223V (Panasonic): Highest seated height at 0.028" (0.70mm), largest current inventory at 203,541 pieces
• RMCF0805FT422K (Stackpole): Seated height of 0.026" (0.65mm), matching original part specification

All four substitute parts are Active status products with RoHS3 compliance and MSL Level 1 rating, identical to the original RC2012F4223CS. Selection between substitutes depends on supply availability, inventory levels, and specific PCB assembly height constraints rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07422KL replace RC2012F4223CS in all applications? A: Yes. Both parts share identical electrical specifications (422 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), composition (thick film), package (0805/2012 Metric), and compliance ratings (RoHS3, MSL 1). The 0.002" (0.06mm) difference in seated height is within standard PCB assembly tolerances.

Q: What is the difference between the Samsung original and YAGEO substitute? A: Electrical and mechanical specifications are identical. The primary differences are manufacturer series designation (RC vs. RC_L) and inventory availability. Both are Active status products with equivalent performance characteristics.

Q: Why do some substitutes have AEC-Q200 qualification? A: CRCW0805422KFKEA, ERJ-6ENF4223V, and RMCF0805FT422K carry automotive AEC-Q200 qualification, indicating compliance with automotive reliability standards. The original RC2012F4223CS does not list this qualification. AEC-Q200 parts are suitable for general applications but are not required unless automotive specifications are mandated.

Q: Are there any height restrictions when selecting a substitute? A: Seated height varies from 0.020" to 0.028" across all parts. Verify PCB assembly clearance specifications. If height-constrained designs require the minimum profile, CRCW0805422KFKEA (0.020") is the lowest option. For standard applications, all parts are interchangeable.

Q: Can I mix different manufacturers in the same PCB assembly? A: Yes. All substitute parts meet identical electrical, mechanical, and compliance specifications. Mixed-manufacturer assemblies are acceptable from an engineering standpoint, though procurement and quality control procedures may apply.

Q: What is the inventory status for each part? A: RC2012F4223CS (Samsung): 754 pieces; RC0805FR-07422KL (YAGEO): 128,215 pieces; CRCW0805422KFKEA (Vishay Dale): 20,359 pieces; ERJ-6ENF4223V (Panasonic): 203,541 pieces; RMCF0805FT422K (Stackpole): 9,432 pieces. Inventory levels influence supply chain decisions but do not affect technical interchangeability.

Q: Are all parts RoHS3 compliant? A: Yes. All five parts (original and four substitutes) are RoHS3 Compliant with MSL Level 1 (Unlimited) rating and REACH Unaffected status, meeting current environmental and regulatory requirements.
