RC5025F90R9CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F90R9CS is a 90.9 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) 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 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are identified when alternative manufacturers offer components with matching electrical specifications (resistance value, tolerance, temperature coefficient) and compatible mechanical packaging, while maintaining compliance with applicable standards and certifications.

Substitute Part Grouping Explanation

Substitute parts for the RC5025F90R9CS are qualified based on the following criteria:

Electrical Compatibility:

• Resistance value: 90.9 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)

Mechanical Compatibility:

• Package type: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Regulatory & Compliance:

• RoHS3 compliance (required)
• MSL rating: 1 (Unlimited) or equivalent (required)

Power Rating Consideration: Substitute parts with equal or higher power ratings (0.667W or greater) are acceptable for direct substitution. Parts with higher power ratings (0.75W) maintain electrical equivalence while providing additional thermal margin.

Parameter Comparison

Engineering Selection Recommendations

CRCW201090R9FKEF (Vishay Dale) is the primary substitute for RC5025F90R9CS. This part maintains all electrical specifications (90.9 Ohms ±1%, ±100ppm/°C temperature coefficient) and mechanical compatibility (2010 package, thick film composition). The higher power rating (0.75W versus 0.667W) provides additional thermal headroom without affecting circuit performance. The part carries Active product status and AEC-Q200 automotive qualification, with ROHS3 compliance and MSL 1 rating identical to the main part.

ERJ-12SF90R9U (Panasonic Electronic Components) is an alternative substitute meeting all electrical and mechanical requirements. This part is electrically equivalent with matching resistance, tolerance, temperature coefficient, and operating temperature range. However, the product status is classified as "Not For New Designs," indicating this part is in mature/legacy phase. The part maintains AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. Selection of this part should be limited to applications requiring compatibility with existing designs or inventory management scenarios.

Both substitute parts are suitable for direct replacement in applications where the RC5025F90R9CS is specified, provided that circuit design accommodates the higher power rating of the substitute parts without adverse effects.

Frequently Asked Questions (FAQ)

Q: Can CRCW201090R9FKEF replace RC5025F90R9CS in all applications?

A: Yes. CRCW201090R9FKEF is electrically and mechanically equivalent to RC5025F90R9CS. Both parts share identical resistance (90.9 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), and package type (2010). The higher power rating (0.75W versus 0.667W) of the Vishay part does not create compatibility issues and provides additional thermal margin.

Q: What is the difference between the 0.667W and 0.75W power ratings?

A: Power rating indicates the maximum continuous power dissipation the resistor can handle without exceeding temperature limits. The 0.75W rating of substitute parts exceeds the 0.667W specification of the main part, meaning substitute parts can safely dissipate equal or greater power levels. This difference does not affect electrical performance in circuits designed for the lower rating.

Q: Why is ERJ-12SF90R9U marked "Not For New Designs"?

A: "Not For New Designs" indicates the part is in mature/legacy phase and the manufacturer is not actively promoting it for new applications. However, the part remains electrically and mechanically equivalent and is suitable for replacement in existing designs or where inventory availability is a consideration.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC5025F90R9CS, CRCW201090R9FKEF, and ERJ-12SF90R9U are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting identical environmental and regulatory requirements.

Q: Can these parts be used interchangeably in automotive applications?

A: CRCW201090R9FKEF and ERJ-12SF90R9U both carry AEC-Q200 automotive qualification. RC5025F90R9CS does not list AEC-Q200 qualification in the provided specifications. For automotive applications requiring AEC-Q200 certification, CRCW201090R9FKEF is the recommended substitute.

Q: What is the physical size difference between these parts?

A: All three parts use the 2010 (5025 Metric) package with identical length and width (0.197" L x 0.098" W / 5.00mm x 2.50mm). Height differences are minimal: RC5025F90R9CS maximum 0.026" (0.66mm), while CRCW201090R9FKEF and ERJ-12SF90R9U maximum 0.028" (0.70mm). These height variations are negligible for PCB assembly compatibility.
