Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: resistance value (9.09 kOhms), tolerance (±1%), power rating (1W), package type (2512/6432 Metric), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), composition (thick film), and regulatory compliance (ROHS3, MSL 1). All identified substitute parts meet these core electrical and mechanical specifications. Additional qualifications such as automotive AEC-Q200 certification represent enhanced capability levels and do not disqualify parts from substitution in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Standard Applications): RC2512FK-079K09L from YAGEO is a direct functional equivalent with identical electrical specifications and ROHS3 compliance. This part is suitable for general-purpose applications where automotive qualification is not required. Inventory availability is 6734 units.

Upgraded Specification (Automotive Applications): AC2512FK-079K09L, CRCW25129K09FKEG, and RMCF2512FT9K09 all carry AEC-Q200 automotive qualification while maintaining full electrical and thermal equivalence to the RC6432F9091CS. These parts are appropriate for automotive or mission-critical applications requiring enhanced reliability certification. AC2512FK-079K09L (4620 units), CRCW25129K09FKEG (18348 units), and RMCF2512FT9K09 (10621 units) are all in active production.

All substitute parts maintain identical resistance, tolerance, power rating, package dimensions, temperature coefficient, and operating temperature range. Selection between substitutes should be based on packaging format preference (tape & reel availability), inventory requirements, and application-specific certification needs.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-079K09L replace RC6432F9091CS in any application? A: Yes. RC2512FK-079K09L meets all core electrical and mechanical specifications: 9.09 kOhms ±1%, 1W power rating, 2512 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and ROHS3 compliance. The primary difference is packaging format (tape & reel versus bulk) and manufacturer (YAGEO versus Samsung).

Q: What is the difference between RC2512FK-079K09L and AC2512FK-079K09L? A: Both are YAGEO products with identical electrical specifications. AC2512FK-079K09L includes AEC-Q200 automotive qualification and is designated for automotive applications. RC2512FK-079K09L is the standard industrial version. Both are functionally interchangeable in non-automotive applications.

Q: Are CRCW25129K09FKEG and RMCF2512FT9K09 interchangeable with RC6432F9091CS? A: Yes. Both parts meet all specified electrical parameters and package requirements. CRCW25129K09FKEG is manufactured by Vishay Dale and RMCF2512FT9K09 by Stackpole Electronics Inc. Both carry AEC-Q200 automotive certification. Dimensional variations are within acceptable tolerances for 2512 package specifications.

Q: Does the tape & reel packaging affect electrical performance? A: No. Packaging format (tape & reel versus bulk) affects handling, storage, and assembly processes but does not alter electrical characteristics, performance, or reliability of the resistor itself.

Q: Which substitute part has the highest inventory availability? A: CRCW25129K09FKEG from Vishay Dale has 18348 units in stock, the highest among all listed substitutes.

Q: Can I use an AEC-Q200 qualified part in a non-automotive application? A: Yes. AEC-Q200 qualification represents an enhanced specification level. Parts meeting automotive standards are fully compatible with general industrial and consumer applications.
