AC2010FK-07348RL Equivalent & Substitute Parts

Part Overview

The AC2010FK-07348RL is a 348 Ohm ±1% thick film chip resistor manufactured by YAGEO in the 2010 (5025 Metric) package format. Rated for 0.75W power dissipation with automotive AEC-Q200 qualification, this component operates across -55°C to 155°C with moisture-resistant construction and ROHS3 compliance. The part is currently in active production status with 2553 units available in inventory.

Substitute parts become necessary when the primary manufacturer experiences supply constraints, lead time extensions, or when design requirements favor alternative qualified sources while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AC2010FK-07348RL is determined by strict equivalence across the following critical parameters:

• Resistance value: 348 Ohms
• Tolerance: ±1%
• Power rating: 0.75W
• Package designation: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• Moisture sensitivity: MSL 1
• RoHS compliance: ROHS3

All substitute parts listed maintain identical electrical specifications and mechanical compatibility. Physical dimensions (0.197" L × 0.098" W / 5.00mm × 2.50mm) and termination count (2) remain constant across all qualified alternatives.

Parameter Comparison

Engineering Selection Recommendations

CRCW2010348RFKEF (Vishay Dale) is the primary substitute option. This part maintains active production status with 12,735 units in inventory, ensuring supply continuity. All electrical and mechanical parameters align with the AC2010FK-07348RL specification. The seated height of 0.028" (0.70mm) versus the original 0.026" (0.65mm) remains within typical PCB assembly tolerances for 2010 package components.

ERJ-12SF3480U (Panasonic) is a secondary substitute with full electrical equivalence and AEC-Q200 automotive qualification. However, this part carries "Not For New Designs" status, limiting its application to legacy system maintenance or existing design continuations where supply of the primary part is unavailable. Inventory availability at 7,338 units supports short-term substitution requirements.

Both substitute parts satisfy ROHS3 compliance, MSL 1 moisture sensitivity, and automotive-grade reliability standards required for the original application context.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010348RFKEF be used as a direct drop-in replacement for AC2010FK-07348RL?

A: Yes. Both parts share identical electrical specifications (348 Ohms ±1%, 0.75W, ±100ppm/°C) and mechanical compatibility (2010 package, 5.00mm × 2.50mm footprint). The 0.002" (0.05mm) height difference falls within standard PCB assembly process windows and does not affect circuit performance or board layout.

Q: Why is ERJ-12SF3480U marked "Not For New Designs"?

A: This designation indicates the manufacturer has transitioned this product line to end-of-life status. While the part remains electrically and mechanically equivalent, it is suitable only for sustaining existing designs or addressing temporary supply gaps. New product development should prioritize CRCW2010348RFKEF or AC2010FK-07348RL.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. CRCW2010348RFKEF and ERJ-12SF3480U both carry AEC-Q200 automotive qualification, matching the original part's reliability and qualification status for automotive applications.

Q: What is the significance of MSL 1 rating for these resistors?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements prior to soldering. All three parts—AC2010FK-07348RL, CRCW2010348RFKEF, and ERJ-12SF3480U—share this rating, eliminating moisture management concerns during storage and assembly.

Q: Can these parts be used interchangeably in high-temperature automotive circuits?

A: Yes. All three parts operate across -55°C to 155°C with ±100ppm/°C temperature coefficient, meeting automotive thermal cycling and operating environment requirements without performance degradation.
