Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AC2512JK-072K7L is determined by strict equivalence in the following critical parameters: resistance value (2.7 kOhms), power rating (1W), package type (2512), composition (thick film), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, REACH Unaffected).

The identified substitute parts maintain these core electrical and mechanical specifications. Variations in tolerance (±5% versus ±1%) and series designation (AC versus RC_L) represent allowable substitutions where the substitute meets or exceeds the original specification requirements. All substitute parts are manufactured by YAGEO and packaged in Tape & Reel format, ensuring compatibility with standard assembly processes.

Parameter Comparison

Engineering Selection Recommendations

RC2512JK-072K7L serves as a direct equivalent substitute, maintaining identical electrical specifications and tolerance while offering increased inventory availability (20,579 pcs versus 1,156 pcs). Both parts carry ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment across applications.

RC2512FK-072K7L represents an upgraded substitute option with tighter tolerance specification (±1% versus ±5%). This part is suitable for applications requiring enhanced precision and stability. The improved tolerance does not compromise compatibility with the original design envelope and maintains all compliance certifications and thermal performance characteristics.

Selection between these parts depends on application-specific tolerance requirements and inventory availability. All three parts are active products with confirmed stock levels and identical mechanical footprints, enabling direct substitution at the assembly level.

Frequently Asked Questions (FAQ)

Q: Can RC2512JK-072K7L be used as a direct replacement for AC2512JK-072K7L?

A: Yes. RC2512JK-072K7L maintains identical resistance value (2.7 kOhms), tolerance (±5%), power rating (1W), package dimensions (2512), and operating temperature range (-55°C ~ 155°C). Both parts are ROHS3 compliant and carry MSL 1 rating.

Q: What is the difference between RC2512JK-072K7L and RC2512FK-072K7L?

A: The primary difference is tolerance specification. RC2512JK-072K7L carries ±5% tolerance, while RC2512FK-072K7L carries ±1% tolerance. All other electrical and mechanical parameters remain identical. RC2512FK-072K7L is suitable for applications requiring tighter resistance accuracy.

Q: Are all substitute parts compatible with existing PCB layouts?

A: Yes. All three parts share identical package type (2512), physical dimensions (0.250" L x 0.122" W), and maximum seated height (0.026"). They are mechanically and electrically interchangeable at the PCB level.

Q: Do the substitute parts maintain automotive qualification?

A: AC2512JK-072K7L carries AEC-Q200 automotive qualification. RC2512JK-072K7L and RC2512FK-072K7L do not list AEC-Q200 qualification in their specifications. For automotive applications requiring AEC-Q200 compliance, AC2512JK-072K7L remains the specified part.

Q: What is the inventory status of each part?

A: AC2512JK-072K7L: 1,156 pcs. RC2512JK-072K7L: 20,579 pcs. RC2512FK-072K7L: 3,907 pcs. All parts are listed as new original stock.
