AC2010FK-07105RL Equivalent & Substitute Parts

Part Overview

The AC2010FK-07105RL is a 105 Ohms ±1% thick film chip resistor rated at 0.75W (3/4W) in the 2010 (5025 Metric) package. This component is manufactured by YAGEO and meets automotive AEC-Q200 qualification with moisture-resistant construction. The part is currently in active production status with 698 units in stock.

The ERJ-12SF1050U from Panasonic Electronic Components serves as an equivalent substitute. However, the Panasonic part carries a "Not For New Designs" status, making it suitable only for legacy system maintenance and repair applications where the original YAGEO specification must be maintained.

Substitute Part Grouping Explanation

Substitution eligibility for the AC2010FK-07105RL is determined by strict equivalence across the following parameters:

• Resistance value: 105 Ohms
• Tolerance: ±1%
• Power rating: 0.75W (3/4W)
• Package type: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• Moisture sensitivity level: MSL 1
• RoHS compliance: ROHS3

The ERJ-12SF1050U meets all electrical and mechanical parameters required for direct substitution. Both parts share identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Both components are AEC-Q200 qualified and ROHS3 compliant, ensuring compatibility in automotive and industrial applications.

Parameter Comparison

Engineering Selection Recommendations

For new design implementations, the AC2010FK-07105RL is the recommended primary selection. This component maintains active production status with established supply chain availability and full automotive qualification.

The ERJ-12SF1050U is suitable for replacement and repair of existing systems where the original YAGEO specification is already in use. The "Not For New Designs" status indicates that Panasonic has transitioned this product line, making it appropriate only for legacy system support and field replacements where design continuity is required.

Both parts meet identical electrical specifications, AEC-Q200 automotive qualification, and ROHS3 compliance requirements. The maximum physical height difference of 0.002" (0.05mm) between the two parts is negligible for standard PCB assembly applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF1050U be used as a direct replacement for AC2010FK-07105RL in new designs?

A: No. While the ERJ-12SF1050U meets all electrical and mechanical parameters, its "Not For New Designs" status indicates that Panasonic no longer supports this part for new applications. The AC2010FK-07105RL should be specified for new designs.

Q: Are there any physical compatibility issues between these two parts?

A: Both parts use the 2010 (5025 Metric) package with identical length and width dimensions (0.197" × 0.098"). The maximum seated height differs by 0.002" (0.05mm), which does not affect PCB assembly or clearance in standard applications.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both AC2010FK-07105RL and ERJ-12SF1050U are AEC-Q200 qualified and suitable for automotive applications requiring this certification.

Q: What is the significance of MSL 1 rating for both parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements. Both parts can be stored and handled without special moisture control procedures.

Q: Are both parts RoHS compliant?

A: Yes. Both components are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
