Substitute Part Grouping Explanation

Substitute parts for the RC5025F4530CS are qualified based on the following criteria:

Electrical Compatibility: Resistance value of 453 Ohms with ±1% tolerance and temperature coefficient of ±100ppm/°C must be maintained.

Mechanical Compatibility: Package type 2010 (5025 Metric) with identical footprint dimensions (0.197" L x 0.098" W) ensures PCB layout compatibility.

Power Rating Consideration: Substitute parts rated at 0.75W (3/4W) exceed the original 0.667W (2/3W) specification, providing thermal margin while maintaining functional equivalence in circuit applications.

Composition & Features: Thick film construction with operating temperature range -55°C ~ 155°C and RoHS3 compliance must be preserved.

Compliance Standards: All substitute parts maintain ROHS3 compliance, MSL Level 1, and REACH Unaffected status.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC5025F4530CS): Use when original Samsung Electro-Mechanics component is specified and available. Active product status with established supply chain.

Substitute Selection (CRCW2010453RFKEF - Vishay Dale): Qualified substitute with higher power rating (0.75W vs 0.667W), automotive AEC-Q200 certification, and active product status. Suitable for applications requiring enhanced thermal performance or automotive-grade reliability.

Substitute Selection (RMCF2010FT453R - Stackpole Electronics): Qualified substitute with higher power rating (0.75W vs 0.667W), automotive AEC-Q200 certification, and active product status. Suitable for applications requiring enhanced thermal performance or automotive-grade reliability.

All three parts maintain identical electrical specifications (453 Ohms ±1%, ±100ppm/°C), mechanical compatibility (2010 package, 5.00mm x 2.50mm footprint), and regulatory compliance (ROHS3, MSL Level 1, REACH Unaffected).

Frequently Asked Questions (FAQ)

Q: Can CRCW2010453RFKEF or RMCF2010FT453R be used as direct replacements for RC5025F4530CS?

A: Yes. Both substitute parts share identical resistance (453 Ohms ±1%), tolerance (±1%), package (2010), dimensions (5.00mm x 2.50mm), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The higher power rating (0.75W vs 0.667W) provides additional thermal margin without affecting circuit function.

Q: What is the difference between the three parts?

A: The primary difference is manufacturer and power rating. RC5025F4530CS (Samsung) is rated at 0.667W with moisture resistant features. CRCW2010453RFKEF (Vishay Dale) and RMCF2010FT453R (Stackpole) are both rated at 0.75W with automotive AEC-Q200 certification. All other electrical and mechanical parameters are equivalent.

Q: Are there packaging differences between these parts?

A: RC5025F4530CS is supplied in standard packaging. CRCW2010453RFKEF and RMCF2010FT453R are supplied in Tape & Reel (TR) format. Physical dimensions and PCB footprint remain identical across all three parts.

Q: Do these parts have the same compliance certifications?

A: Yes. All three parts are ROHS3 compliant, MSL Level 1 (Unlimited), REACH Unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030.

Q: Which substitute should be selected for automotive applications?

A: Both CRCW2010453RFKEF and RMCF2010FT453R carry automotive AEC-Q200 certification, making them suitable for automotive-grade applications. RC5025F4530CS does not carry this certification.
