RC5025F3480CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F3480CS is a 348 Ohm ±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) continuous 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 715 units currently in stock.

Substitute parts are necessary when the original manufacturer part becomes unavailable, when design requirements demand higher power ratings, automotive-grade certifications, or when supply chain optimization requires alternative sourcing from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F3480CS is determined by strict adherence to the following parameters:

Critical Parameters (Must Match Exactly):

• Resistance value: 348 Ohms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture resistance capability
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variation:

• Power rating: Substitute parts may have equal or higher power ratings (0.75W/3/4W acceptable for 0.667W/2/3W applications)
• Packaging format: Tape & Reel (TR) acceptable as alternative to standard packaging
• Additional certifications: Automotive AEC-Q200 qualification is an enhancement, not a restriction

All three substitute parts meet these criteria and are electrically and mechanically compatible with the RC5025F3480CS.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Recommended for New Designs):

CRCW2010348RFKEF (Vishay Dale) is the preferred substitute for new design implementations. This part maintains Active product status, offers the highest inventory availability at 12,735 units, and provides automotive-grade AEC-Q200 certification. The 0.75W power rating provides design margin over the original 0.667W specification while maintaining identical electrical and mechanical compatibility.

Secondary Selection (Active Alternative):

AC2010FK-07348RL (YAGEO) serves as an active alternative with 2,553 units in stock. This part includes both moisture-resistant construction and AEC-Q200 automotive qualification, matching the enhanced feature set of the Vishay option while offering a different manufacturer source for supply chain diversification.

Legacy Consideration (Not Recommended for New Designs):

ERJ-12SF3480U (Panasonic Electronic Components) carries a "Not For New Designs" product status designation. While electrically and mechanically compatible, this part should be reserved for legacy system maintenance and repair applications only. New design implementations should not incorporate this component.

Original Part Retention:

RC5025F3480CS (Samsung Electro-Mechanics) maintains Active status with adequate inventory. Retention of the original part is appropriate when supply is confirmed and no design enhancement requirements exist.

Frequently Asked Questions (FAQ)

Q: Can I use a 0.75W (3/4W) rated resistor in place of the 0.667W (2/3W) original part?

A: Yes. The substitute parts with 0.75W ratings are directly compatible. Higher power ratings provide additional thermal margin and do not affect circuit performance when the original design current does not exceed the lower rating specification.

Q: Are the substitute parts physically identical to the RC5025F3480CS?

A: Yes. All substitute parts use the 2010 (5025 Metric) package format with identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm) dimensions. Height variation is negligible (0.026" to 0.028" seated maximum), presenting no mechanical compatibility issues in standard PCB layouts.

Q: What is the significance of AEC-Q200 certification on the substitute parts?

A: AEC-Q200 is an automotive industry qualification standard. Parts bearing this certification have undergone additional reliability testing and are suitable for automotive applications. This certification does not restrict use in non-automotive applications and represents an enhancement to the original part specification.

Q: Why is the Panasonic ERJ-12SF3480U marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and promotion of this product line. While the part remains functionally compatible and available in inventory, design engineers should select from Active status alternatives (Vishay or YAGEO) for new product development to ensure long-term supply continuity.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, matching the original RC5025F3480CS specification and meeting current environmental and regulatory requirements.

Q: Can I mix different manufacturers' parts in the same production batch?

A: Yes. All substitute parts meet identical electrical specifications (348 Ohms ±1%, ±100ppm/°C, -55°C to 155°C operating range) and mechanical package requirements (2010 format). Manufacturing source variation does not affect circuit performance or reliability when parts are sourced from qualified suppliers with confirmed inventory.
