Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F82R5CS is determined by strict equivalence in the following core parameters: resistance value (82.5 Ohms), tolerance (±1%), package type (2512 / 6432 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). All identified substitute parts maintain these specifications.

The substitute parts are grouped into two categories based on power rating and additional features:

Category 1: Direct 1W Equivalent – CRCW251282R5FKEG maintains identical 1W power rating with automotive AEC-Q200 qualification.

Category 2: Enhanced Performance – CRCW251282R5FKEGHP provides increased 1.5W power rating with pulse withstanding capability, also automotive AEC-Q200 qualified.

Both substitutes are manufactured by Vishay Dale and supplied in Tape & Reel packaging. All parts comply with ROHS3, maintain MSL 1 rating, and are REACH Unaffected.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: CRCW251282R5FKEG is the appropriate substitute when 1W power rating is required and automotive AEC-Q200 qualification is beneficial. This part maintains all electrical specifications of the RC6432F82R5CS while offering automotive-grade reliability.

For Enhanced Margin Applications: CRCW251282R5FKEGHP is selected when circuit design requires increased power dissipation margin or pulse withstanding capability. The 1.5W rating provides 50% additional power capacity within the same 2512 package footprint. This part is suitable for applications where transient power events or thermal margin is a design consideration.

Compliance Considerations: All three parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating. Selection between parts should be based on application power requirements and automotive qualification necessity, not compliance factors.

Physical Compatibility: Slight dimensional variations exist in width (0.126" vs 0.124") and height (0.026" vs 0.028"). Verify PCB layout and assembly equipment compatibility for the Vishay substitutes before implementation.

Frequently Asked Questions (FAQ)

Q: Can CRCW251282R5FKEG directly replace RC6432F82R5CS in any circuit?

A: Yes, for circuits designed for 1W power dissipation. The electrical specifications are equivalent. Verify PCB layout accommodates the slight dimensional differences (width 0.124" vs 0.126", height 0.028" vs 0.026").

Q: What is the advantage of CRCW251282R5FKEGHP over the standard 1W substitute?

A: CRCW251282R5FKEGHP provides 1.5W power rating and pulse withstanding capability within the same 2512 package. Use this part when circuit analysis indicates power dissipation approaching 1W or when transient power events occur.

Q: Are the Vishay substitutes automotive-qualified?

A: Yes. Both CRCW251282R5FKEG and CRCW251282R5FKEGHP carry AEC-Q200 automotive qualification. The original RC6432F82R5CS does not specify automotive qualification.

Q: Do all three parts have identical temperature performance?

A: Yes. All parts share ±100ppm/°C temperature coefficient and -55°C ~ 155°C operating range.

Q: What packaging format is supplied for the substitutes?

A: Both Vishay substitutes are supplied in Tape & Reel (TR) format. The original RC6432F82R5CS packaging format is not specified in the provided data.

Q: Are there any RoHS or environmental compliance differences?

A: No. All three parts are ROHS3 compliant, REACH Unaffected, and maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can CRCW251282R5FKEGHP be used in place of the 1W part without circuit modification?

A: Yes. The 1.5W rating is a superset of 1W requirements. No circuit modification is necessary. The part is electrically and mechanically compatible within the noted dimensional tolerances.
