RC5025F2742CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F2742CS is a 27.4 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) surface mount package. This component is classified as Active product status with moisture resistant characteristics and operates across the temperature range of -55°C to 155°C. The part is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit higher power ratings or enhanced automotive qualification levels. The substitute parts listed maintain electrical equivalence through identical resistance value, tolerance, and temperature coefficient specifications while offering alternative packaging formats or enhanced feature sets.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F2742CS is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Resistance value: 27.4 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Package / Case: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)

Secondary Compatibility Parameters:

• Power Rating: Substitute parts rated at 0.75W (3/4W) or higher are electrically compatible, as they exceed the 0.667W requirement of the main part
• Packaging Format: Both bulk and Tape & Reel formats are mechanically compatible
• Compliance: ROHS3 and REACH compliance maintained across all substitutes

The identified substitute parts CRCW201027K4FKEF (Vishay Dale) and ERJ-12SF2742U (Panasonic Electronic Components) satisfy all primary criteria and offer enhanced power ratings of 0.75W, providing additional design margin.

Parameter Comparison

Engineering Selection Recommendations

CRCW201027K4FKEF (Vishay Dale) is the primary recommended substitute for the RC5025F2742CS. This part maintains full electrical equivalence across all critical parameters while offering a 0.75W power rating that exceeds the original specification. The component carries Active product status, ensuring continued availability and manufacturing support. Automotive AEC-Q200 qualification provides enhanced reliability documentation suitable for demanding applications. The Tape & Reel packaging format supports automated assembly processes.

ERJ-12SF2742U (Panasonic Electronic Components) is a secondary substitute option. While electrically equivalent and mechanically compatible, this part carries a "Not For New Designs" product status designation. This classification indicates that Panasonic has discontinued active development and marketing of this component line. Use of ERJ-12SF2742U is restricted to legacy system maintenance, repair, or applications where existing design validation has already been completed. The part remains available in current inventory (840 Pcs) but should not be selected for new product development initiatives.

Both substitute parts are ROHS3 compliant and maintain MSL 1 moisture sensitivity ratings, ensuring compatibility with standard PCB assembly and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can CRCW201027K4FKEF replace RC5025F2742CS in all applications?

A: Yes. The CRCW201027K4FKEF maintains identical electrical specifications (27.4 kOhms ±1%, ±100ppm/°C, -55°C to 155°C operating range) and identical mechanical package (2010 / 5025 Metric). The higher power rating (0.75W vs. 0.667W) provides additional design margin without introducing compatibility issues. Both parts are ROHS3 compliant with MSL 1 ratings.

Q: What is the significance of the "Not For New Designs" status on ERJ-12SF2742U?

A: This designation indicates that Panasonic has transitioned this product line away from active development and marketing. While the part remains electrically and mechanically equivalent, it should only be used for repair, maintenance, or completion of existing designs. New product development should utilize CRCW201027K4FKEF or equivalent active-status alternatives.

Q: Are there height differences between the main part and substitutes?

A: Yes. The RC5025F2742CS has a maximum seated height of 0.026" (0.66mm), while both substitute parts (CRCW201027K4FKEF and ERJ-12SF2742U) have a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not affect functionality. Verify clearance in applications with height-critical constraints.

Q: Do the substitute parts support the same packaging formats?

A: The RC5025F2742CS is supplied in standard packaging (format not specified in data). Both CRCW201027K4FKEF and ERJ-12SF2742U are available in Tape & Reel (TR) format, which is standard for automated assembly. Confirm packaging requirements with your procurement specification before ordering.

Q: Are all three parts suitable for automotive applications?

A: CRCW201027K4FKEF carries Automotive AEC-Q200 qualification, explicitly supporting automotive-grade applications. RC5025F2742CS and ERJ-12SF2742U do not list automotive qualification in their specifications. If automotive AEC-Q200 compliance is a design requirement, CRCW201027K4FKEF is the appropriate selection.

Q: What is the inventory status for each part?

A: RC5025F2742CS: 1141 Pcs in stock. CRCW201027K4FKEF: 6048 Pcs in stock. ERJ-12SF2742U: 840 Pcs in stock. All parts are listed as New Original stock.
