RC5025F3323CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F3323CS is a 332 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format with a power rating of 0.667W (2/3W). This component is classified as Active product status with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. Substitute parts are identified when electrical specifications (resistance value, tolerance, power rating, temperature coefficient, and operating temperature range) and mechanical parameters (package format, dimensions, and termination count) align within acceptable engineering tolerances for direct component replacement in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F3323CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 332 kOhms
• Tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Composition: Thick Film

Mechanical Parameters (Must Match):

• Package format: 2010 (5025 Metric)
• Dimensions: 5.00mm L x 2.50mm W
• Number of terminations: 2

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant status
• Moisture Sensitivity Level: 1 (Unlimited)

Power Rating Consideration: Substitute parts with equal or higher power ratings (0.667W or greater) are acceptable for direct replacement. The RC5025F3323CS operates at 0.667W (2/3W); substitute parts rated at 0.75W (3/4W) or higher maintain thermal margin and circuit reliability.

Parameter Comparison

Engineering Selection Recommendations

CRCW2010332KFKEF (Vishay Dale) is the primary substitute for the RC5025F3323CS. This part maintains all critical electrical parameters (332 kOhms ±1%, ±100ppm/°C, -55°C to 155°C operating range) and mechanical specifications (2010 package, 5.00 x 2.50 mm dimensions). The CRCW2010332KFKEF features a higher power rating of 0.75W (3/4W) compared to the original 0.667W specification, providing additional thermal margin. Both parts are ROHS3 Compliant with MSL 1 (Unlimited) rating. The Vishay Dale part carries Active product status and includes AEC-Q200 automotive qualification, making it suitable for both commercial and automotive applications.

ERJ-12SF3323U (Panasonic Electronic Components) is a secondary substitute option. This part matches all electrical and mechanical parameters identically to the CRCW2010332KFKEF, including the 0.75W power rating and AEC-Q200 automotive qualification. However, the ERJ-12SF3323U is designated as "Not For New Designs," indicating that Panasonic has discontinued active development and support for this product line. This classification restricts its use to legacy system maintenance and repair applications only. For new circuit designs, the CRCW2010332KFKEF is the recommended choice.

Frequently Asked Questions (FAQ)

Q: Can the CRCW2010332KFKEF directly replace the RC5025F3323CS in existing circuits?

A: Yes. Both parts share identical electrical specifications (332 kOhms ±1%, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and mechanical parameters (2010 package, 5.00 x 2.50 mm dimensions, 2 terminations). The CRCW2010332KFKEF power rating of 0.75W exceeds the original 0.667W specification, ensuring thermal compatibility. Both parts are ROHS3 Compliant with MSL 1 rating.

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

A: The RC5025F3323CS is rated at 0.667W (2/3W), while substitute parts CRCW2010332KFKEF and ERJ-12SF3323U are rated at 0.75W (3/4W). A higher power rating indicates greater thermal dissipation capability. Substituting a higher-rated part maintains or improves circuit reliability by providing additional thermal margin without affecting electrical performance.

Q: Why is the ERJ-12SF3323U marked "Not For New Designs"?

A: The "Not For New Designs" designation indicates that Panasonic has transitioned this product to end-of-life status and no longer actively supports new applications. While the part remains electrically and mechanically compatible with the RC5025F3323CS, it is restricted to legacy system maintenance and repair. For new circuit designs, use the CRCW2010332KFKEF (Vishay Dale) instead.

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

A: The RC5025F3323CS has a maximum seated height of 0.66 mm, while both substitute parts (CRCW2010332KFKEF and ERJ-12SF3323U) have a maximum seated height of 0.70 mm. This 0.04 mm difference is within standard PCB assembly tolerances and does not affect component placement or circuit board clearance in standard applications.

Q: Do all three parts meet automotive qualification standards?

A: The RC5025F3323CS does not list automotive qualification in its specifications. The CRCW2010332KFKEF and ERJ-12SF3323U both carry AEC-Q200 automotive qualification, making them suitable for automotive applications. If automotive qualification is required, use the CRCW2010332KFKEF (Active status) or ERJ-12SF3323U (legacy applications only).

Q: What packaging formats are available for these parts?

A: The RC5025F3323CS is supplied in standard packaging format. The CRCW2010332KFKEF and ERJ-12SF3323U are supplied in Tape & Reel (TR) format, which is standard for high-volume automated assembly. Both formats are compatible with standard PCB assembly equipment.
