RC5025F4223CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F4223CS is a 422 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) in a 2010 (5025 Metric) package. This component is classified as Active product status and features moisture-resistant construction suitable for general industrial applications.

Substitute parts become necessary when the primary component experiences supply constraints, inventory depletion, or when design requirements permit alternative manufacturers meeting equivalent electrical and mechanical specifications. The RC5025F4223CS maintains 824 pieces in current inventory; however, alternative sources with compatible parameters ensure design continuity and procurement flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F4223CS is determined by strict alignment with the following parameters:

Critical Matching Parameters:

• Resistance value: 422 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package designation: 2010 (5025 Metric) (exact match required)
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) (exact match required)
• Composition: Thick Film (exact match required)

Acceptable Variation Parameters:

• Power rating: Substitute must equal or exceed 0.667W minimum
• Temperature coefficient: ±100ppm/°C or better
• Operating temperature range: Must encompass -55°C ~ 155°C minimum
• RoHS compliance: ROHS3 Compliant required
• Moisture sensitivity: MSL 1 acceptable

The ERJ-12SF4223U qualifies as a direct substitute based on matching all critical parameters while exceeding the power rating specification (0.75W vs. 0.667W required).

Parameter Comparison

Engineering Selection Recommendations

RC5025F4223CS (Primary Selection): The RC5025F4223CS maintains Active product status, indicating ongoing manufacturer support and continued availability. This component is suitable for new designs and applications requiring long-term supply assurance. Current inventory of 824 pieces supports immediate procurement requirements.

ERJ-12SF4223U (Substitute Selection): The ERJ-12SF4223U qualifies as an electrical and mechanical equivalent based on matching resistance, tolerance, package, and thermal specifications. However, this component carries "Not For New Designs" status, indicating the manufacturer has discontinued active development. The ERJ-12SF4223U is appropriate for:

• Replacement in existing production runs where supply of the primary part is unavailable
• Maintenance and repair applications for fielded equipment
• Situations where inventory of the primary part is exhausted

The substitute's higher power rating (0.75W vs. 0.667W) provides thermal margin and does not create compatibility issues in circuits designed for the primary component.

Compliance Considerations: Both components maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, ensuring regulatory alignment and identical handling requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF4223U be used as a direct replacement for RC5025F4223CS in new product designs?

A: No. The ERJ-12SF4223U carries "Not For New Designs" status from the manufacturer. New designs should specify the RC5025F4223CS or identify alternative active-status components with equivalent parameters. The substitute is appropriate only for existing production continuity or field replacement scenarios.

Q: Does the higher power rating of ERJ-12SF4223U (0.75W vs. 0.667W) create any compatibility issues?

A: No. A higher power rating indicates greater thermal capacity and does not degrade circuit performance. Circuits designed for 0.667W operation function correctly with a 0.75W component. The substitute provides additional thermal margin.

Q: Are the physical dimensions identical between the two components?

A: The package designation (2010/5025 Metric) and primary dimensions (5.00mm x 2.50mm) are identical. The seated height differs slightly (0.66mm vs. 0.70mm maximum), which remains within standard PCB assembly tolerances and does not affect footprint compatibility.

Q: What is the significance of the "Not For New Designs" status on the ERJ-12SF4223U?

A: This designation indicates Panasonic has transitioned this component to end-of-life status and is not actively developing or promoting it for new applications. Existing inventory may be available, but long-term supply cannot be guaranteed. New designs should avoid this component.

Q: Do both components require identical handling and storage procedures?

A: Yes. Both components maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control is required during storage or handling. Standard component storage conditions apply to both parts.

Q: Can the ERJ-12SF4223U be used in automotive applications?

A: The ERJ-12SF4223U carries AEC-Q200 automotive qualification. The RC5025F4223CS does not list automotive certification. If automotive qualification is required, the ERJ-12SF4223U provides this additional certification; however, design validation should confirm this meets specific application requirements.
