AC1206FR-07240KL Equivalent & Substitute Parts

Part Overview

The AC1206FR-07240KL is a 240 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by YAGEO. This automotive-grade component features AEC-Q200 qualification and moisture resistance, designed for applications requiring reliable performance across -55°C to 155°C operating temperature range. Substitute parts are necessary to address supply availability, packaging preferences, or specific feature requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (240 kOhms), tolerance (±1%), power rating (0.25W), package type (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected). All listed substitute parts meet these core electrical and mechanical requirements. Variations in physical dimensions (length, width, height) within the 1206 package specification, packaging format (Tape & Reel vs. Cut Tape), and optional features (AEC-Q200 automotive rating, moisture resistance, high voltage capability) do not affect functional substitutability for this resistance value and tolerance class.

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from: RK73H2BTTD2403F (KOA Speer), CRCW1206240KFKEA (Vishay Dale), KTR18EZPF2403 (Rohm), or RMCF1206FT240K (Stackpole). These parts maintain active product status and full compliance with automotive standards.

For general-purpose applications where automotive qualification is not required, RC1206FR-07240KL (YAGEO), CR1206-FX-2403ELF (Bourns), or MCR18ERTF2403 (Rohm) are electrically equivalent alternatives. Note that MCR18ERTF2403 is discontinued at DiGi Electronics and ERJ-8ENF2403V (Panasonic) is marked "Not For New Designs," limiting their suitability for new product development.

All substitute parts maintain identical electrical specifications (240 kOhms ±1%, 0.25W, ±100ppm/°C) and operating temperature range (-55°C to 155°C). Selection should prioritize parts with active product status and required certifications for the intended application.

Frequently Asked Questions (FAQ)

Q: Can I substitute AC1206FR-07240KL with RC1206FR-07240KL? A: Yes. Both are YAGEO 240 kOhms ±1% 1206 resistors with identical electrical specifications. The primary difference is packaging format (Tape & Reel vs. Cut Tape & Digi-Reel). RC1206FR-07240KL lacks AEC-Q200 automotive qualification, so it is suitable only for non-automotive applications.

Q: What is the difference between AEC-Q200 and non-AEC-Q200 versions? A: AEC-Q200 certification indicates the part meets automotive industry reliability and qualification standards. For automotive applications, use AEC-Q200 qualified parts. For consumer or industrial applications without automotive requirements, non-AEC-Q200 parts are functionally equivalent.

Q: Are all substitute parts physically interchangeable? A: Yes. All parts use the 1206 (3216 Metric) package. Minor variations in physical dimensions (length 0.120" to 0.126", height 0.024" to 0.030") fall within standard 1206 package tolerances and do not affect PCB footprint compatibility or assembly.

Q: Can I use ERJ-8ENF2403V or MCR18ERTF2403 for new designs? A: ERJ-8ENF2403V is marked "Not For New Designs" and MCR18ERTF2403 is discontinued. For new product development, select from parts with "Active" product status: RC1206FR-07240KL, RK73H2BTTD2403F, CR1206-FX-2403ELF, CRCW1206240KFKEA, KTR18EZPF2403, or RMCF1206FT240K.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance? A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical and mechanical specifications remain identical regardless of packaging type.

Q: What does Moisture Sensitivity Level 1 mean? A: MSL 1 indicates unlimited shelf life without moisture control requirements. The component does not require special dry storage or baking procedures before assembly.
