AC1210FR-07105RL Equivalent & Substitute Parts

Part Overview

The AC1210FR-07105RL is a 105 Ohm ±1% thick film chip resistor in 1210 (3225 Metric) package rated for 0.5W power dissipation. Manufactured by YAGEO under the AC series, this component is AEC-Q200 automotive qualified with moisture resistance and operates across -55°C to 155°C. The part is currently active in production with 649 units in stock.

Substitute parts become necessary when primary inventory is depleted, when design requirements mandate alternative manufacturer qualifications, or when supply chain optimization requires component standardization across multiple suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AC1210FR-07105RL is determined by strict equivalence across the following parameters:

• Resistance value: 105 Ohms
• Tolerance: ±1%
• Power rating: 0.5W minimum
• Package: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• Automotive qualification: AEC-Q200
• Moisture sensitivity: MSL 1 or better
• RoHS compliance: ROHS3

Two substitute parts meet these criteria: CRCW1210105RFKEA (Vishay Dale) and ERJ-14NF1050U (Panasonic Electronic Components). Both maintain identical electrical specifications and package dimensions within acceptable mechanical tolerances.

Parameter Comparison

Engineering Selection Recommendations

CRCW1210105RFKEA (Vishay Dale) is the primary substitute for new designs and ongoing production. This part maintains active product status, identical electrical specifications, and matching mechanical dimensions with maximum seated height of 0.024" (0.60mm), ensuring direct PCB compatibility with the original AC1210FR-07105RL.

ERJ-14NF1050U (Panasonic Electronic Components) is functionally equivalent but carries "Not For New Designs" status. This part is suitable only for legacy system maintenance, repair, or applications where existing inventory must be consumed. The maximum seated height of 0.028" (0.70mm) represents a 0.004" (0.10mm) increase over the primary part and original specification, requiring mechanical clearance verification before implementation.

Both substitutes maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating, confirming suitability for automotive and industrial applications operating within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can CRCW1210105RFKEA be used as a direct replacement for AC1210FR-07105RL?

A: Yes. Both parts share identical electrical specifications (105 Ohms ±1%, 0.5W, ±100ppm/°C), package designation (1210/3225 Metric), and mechanical dimensions (0.024" maximum seated height). AEC-Q200 qualification and ROHS3 compliance are equivalent.

Q: Why is ERJ-14NF1050U marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new applications. The part remains available for existing inventory and legacy system support but should not be selected for new designs.

Q: Does the 0.004" height difference of ERJ-14NF1050U affect PCB compatibility?

A: The ERJ-14NF1050U maximum seated height of 0.028" (0.70mm) versus 0.024" (0.60mm) for the original part requires verification of available PCB clearance. If the original design includes height-constrained routing or component stacking, this difference may necessitate layout modification.

Q: Are all three parts suitable for automotive applications?

A: Yes. AC1210FR-07105RL, CRCW1210105RFKEA, and ERJ-14NF1050U all carry AEC-Q200 automotive qualification and operate across -55°C to 155°C, meeting automotive temperature and reliability requirements.

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

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake-out requirements. All three parts can be stored and handled under standard conditions without special moisture control procedures.
