RC5025F9093CS Equivalent & Substitute Parts

Part Overview

The RC5025F9093CS is a 909 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 and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same resistance value, tolerance, package footprint, and operating temperature range. The primary substitute identified is the ERJ-12SF9093U from Panasonic Electronic Components, which maintains identical resistance and tolerance specifications while offering increased power rating and automotive-grade qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F9093CS is determined by strict alignment with the following critical parameters:

Electrical Parameters (Must Match):

• Resistance value: 909 kOhms
• Tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 2010 (5025 Metric)
• Footprint dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm)
• Number of terminations: 2

Allowable Variation:

• Power rating may exceed the original specification (0.667W minimum required)
• Height seated maximum may vary within component tolerance
• Composition must remain thick film

The ERJ-12SF9093U qualifies as a direct substitute because it maintains identical resistance, tolerance, temperature coefficient, operating temperature range, and package footprint. The increased power rating (0.75W vs. 0.667W) provides additional thermal margin and does not compromise circuit compatibility.

Engineering Selection Recommendations

RC5025F9093CS (Samsung Electro-Mechanics) - Primary Selection:

• Active product status ensures continued availability and manufacturing support
• ROHS3 compliance required for applications subject to environmental regulations
• Moisture sensitivity level 1 (unlimited) suitable for standard storage and handling
• Recommended for new designs and long-term production requirements

ERJ-12SF9093U (Panasonic Electronic Components) - Substitute Selection:

• Electrical and mechanical compatibility confirmed across all critical parameters
• Higher power rating (0.75W) provides thermal design margin
• AEC-Q200 automotive qualification available for automotive applications
• Product status "Not For New Designs" indicates potential supply constraints; suitable for legacy system maintenance or replacement applications only
• RoHS non-compliance requires verification against application regulatory requirements before selection

Compliance Considerations: Selection between these parts must account for RoHS compliance mandates. The RC5025F9093CS is the compliant choice for regulated applications. The ERJ-12SF9093U substitution is technically valid but introduces compliance risk in RoHS-regulated markets.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF9093U replace RC5025F9093CS in new product designs?

A: Electrical and mechanical compatibility is confirmed. However, the ERJ-12SF9093U carries "Not For New Designs" status, indicating Panasonic does not recommend this part for new applications. The RC5025F9093CS is the appropriate choice for new designs.

Q: What is the impact of the higher power rating on ERJ-12SF9093U?

A: The ERJ-12SF9093U is rated for 0.75W versus the RC5025F9093CS at 0.667W. This higher rating does not create compatibility issues; it provides additional thermal margin. The substitute can safely operate in circuits designed for the lower-rated original part.

Q: Are the physical dimensions identical between these parts?

A: Both parts use the 2010 (5025 Metric) package with identical footprint dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm). The seated height differs slightly (0.026" vs. 0.028"), but both values fall within standard component tolerance and do not affect PCB assembly compatibility.

Q: What is the significance of the RoHS compliance difference?

A: The RC5025F9093CS is ROHS3 compliant; the ERJ-12SF9093U is not. Applications subject to RoHS regulations (EU, California, and other jurisdictions) must use the RC5025F9093CS. Non-regulated applications may use either part based on availability.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes, from an electrical and mechanical standpoint. Both parts maintain identical resistance (909 kOhms ±1%), tolerance, temperature coefficient, and operating range. Substitution is valid for replacement or repair of existing assemblies, subject to compliance verification.

Q: What packaging formats are available?

A: The RC5025F9093CS is supplied in standard packaging (format not specified in data). The ERJ-12SF9093U is supplied in Tape & Reel (TR) format, which is standard for high-volume automated assembly. Packaging format should be verified with the supplier for procurement requirements.
