RC5025F4023CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F4023CS is a 402 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format. This component is rated for 0.667W (2/3W) power dissipation with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with 1103 units currently in stock inventory.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope. Alternative sources become necessary for supply chain continuity, extended lead time mitigation, or design flexibility across manufacturing partners.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F4023CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 402 kOhms
• Tolerance: ±1%
• Package footprint: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture sensitivity level: MSL 1 or better
• RoHS compliance: ROHS3 Compliant

Allowable Variation:

• Power rating: Substitute parts rated at 0.75W (3/4W) or higher satisfy the 0.667W requirement of the main part, provided all other parameters remain equivalent.

The identified substitute parts meet all mandatory parameters while maintaining or exceeding the power dissipation capability of the original specification.

Engineering Selection Recommendations

RC5025F4023CS (Samsung Electro-Mechanics) - Primary Selection

The RC5025F4023CS maintains Active product status with established supply availability (1103 units in stock). This part is suitable for new designs and ongoing production requirements. The moisture-resistant thick film construction and ROHS3 compliance support standard industrial and commercial applications.

CRCW2010402KFKEF (Vishay Dale) - Preferred Substitute

The CRCW2010402KFKEF is recommended as the primary substitute option. This part carries Active product status, ensuring long-term availability and design continuity. The higher power rating (0.75W versus 0.667W) provides additional thermal margin while maintaining identical electrical and mechanical specifications. Automotive AEC-Q200 qualification indicates enhanced reliability screening. Inventory availability is substantial (4267 units in stock).

ERJ-12SF4023U (Panasonic Electronic Components) - Secondary Substitute

The ERJ-12SF4023U meets all electrical and mechanical compatibility requirements with identical resistance, tolerance, temperature coefficient, and package specifications. However, this part carries a "Not For New Designs" product status designation, limiting its application to legacy system support or replacement scenarios only. Inventory is available (10689 units in stock), but this part should not be selected for new design implementations.

Frequently Asked Questions (FAQ)

Q: Can the CRCW2010402KFKEF replace the RC5025F4023CS in existing designs?

A: Yes. The CRCW2010402KFKEF is electrically and mechanically equivalent to the RC5025F4023CS. Both parts share identical resistance (402 kOhms), tolerance (±1%), package footprint (2010/5025 Metric), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The substitute part's higher power rating (0.75W) exceeds the original specification (0.667W), providing additional thermal capability without affecting circuit performance.

Q: What is the difference in physical dimensions between the main part and substitutes?

A: The length and width dimensions are identical across all three parts: 0.197" L x 0.098" W (5.00mm x 2.50mm). The seated height differs slightly: RC5025F4023CS measures 0.026" (0.66mm) maximum, while both CRCW2010402KFKEF and ERJ-12SF4023U measure 0.028" (0.70mm) maximum. This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not affect board-level compatibility.

Q: Why is the ERJ-12SF4023U marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has designated this part for legacy support only. While the part remains functionally equivalent and currently in stock, it should not be incorporated into new product designs. This designation typically reflects manufacturer's long-term product roadmap decisions. For new designs, select either the RC5025F4023CS or CRCW2010402KFKEF.

Q: Are all three parts RoHS3 compliant?

A: Yes. The RC5025F4023CS, CRCW2010402KFKEF, and ERJ-12SF4023U are all ROHS3 Compliant. All three parts carry MSL 1 (Unlimited) moisture sensitivity level rating, indicating no special moisture handling requirements during storage or assembly.

Q: What is the significance of the AEC-Q200 qualification on the CRCW2010402KFKEF?

A: AEC-Q200 is an automotive industry qualification standard that specifies enhanced reliability testing and screening procedures for passive components. The CRCW2010402KFKEF's AEC-Q200 rating indicates it has undergone additional qualification testing beyond standard commercial specifications. This qualification is beneficial for automotive applications or systems requiring enhanced reliability assurance, though it is not required for general industrial or commercial use.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All three parts share identical operating temperature specifications (-55°C to 155°C) and temperature coefficient (±100ppm/°C). They are interchangeable for applications within this temperature range. The temperature coefficient value indicates that resistance will vary by approximately ±100 parts per million for each degree Celsius change from the reference temperature.
