Substitute Part Grouping Explanation

Substitute parts for the AC2010FK-07402RL are qualified based on the following criteria:

• Identical resistance value: 402 Ohms
• Matching tolerance: ±1%
• Equivalent power rating: 0.75W
• Same package: 2010 (5025 Metric)
• Identical composition: Thick Film
• Matching temperature coefficient: ±100ppm/°C
• Overlapping operating temperature range: -55°C ~ 155°C
• AEC-Q200 automotive qualification
• ROHS3 compliance
• MSL 1 rating

All identified substitutes meet these electrical and mechanical parameters, ensuring direct functional equivalence in automotive applications.

Parameter Comparison

Engineering Selection Recommendations

CRCW2010402RFKEF (Vishay Dale) is the primary substitute for new designs. This part maintains active production status, carries full AEC-Q200 automotive qualification, and demonstrates high inventory availability (26,256 pcs). Electrical and mechanical parameters are identical to the AC2010FK-07402RL, with only a marginal height difference (0.028" vs 0.026") that remains within standard PCB assembly tolerances.

ERJ-12SF4020U (Panasonic Electronic Components) is functionally equivalent but carries "Not For New Designs" status. This designation indicates the manufacturer is phasing out this product line. While the part meets all electrical specifications and AEC-Q200 requirements, it should be used only for legacy system maintenance or repair applications where supply continuity is not a design consideration.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010402RFKEF directly replace AC2010FK-07402RL in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified, share identical electrical specifications (402 Ohms ±1%, 0.75W, ±100ppm/°C), and use the same 2010 (5025 Metric) package. The 0.002" height difference (0.028" vs 0.026") is within standard PCB assembly tolerances and does not affect functionality or reliability.

Q: Why is ERJ-12SF4020U marked "Not For New Designs"?

A: This designation indicates Panasonic has discontinued active development and is transitioning away from this product line. The part remains functionally equivalent and available for existing applications, but new designs should prioritize CRCW2010402RFKEF or AC2010FK-07402RL for long-term supply assurance.

Q: Are all substitutes ROHS3 compliant?

A: Yes. AC2010FK-07402RL, CRCW2010402RFKEF, and ERJ-12SF4020U are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, meeting environmental and regulatory requirements for automotive applications.

Q: What determines substitutability for this 402 Ohm resistor?

A: Substitutability is determined by matching resistance value (402 Ohms), tolerance (±1%), power rating (0.75W), package type (2010), composition (Thick Film), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. All identified substitutes meet these criteria.

Q: Can I use these parts interchangeably in high-temperature automotive circuits?

A: Yes. All three parts operate across the identical temperature range (-55°C ~ 155°C) with matching temperature coefficients (±100ppm/°C), ensuring consistent performance in automotive thermal environments.
