AC1206FR-07105RL Equivalent & Substitute Parts

Part Overview

The AC1206FR-07105RL is a 105 Ohm ±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, making it suitable for demanding automotive and industrial applications operating across -55°C to 155°C. The part is currently active in production with 922 units in stock.

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility allows for equivalent alternatives from different manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AC1206FR-07105RL is determined by strict equivalence across the following parameters:

• Resistance value: 105 Ohms
• Tolerance: ±1%
• Power rating: 0.25W
• Package designation: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All qualified substitutes maintain these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within standard 1206 package tolerances and differences in packaging format (Tape & Reel vs. Cut Tape) do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Recommended): RC1206FR-07105RL (YAGEO)

This part maintains full electrical equivalence with the main part number. Both are from the same manufacturer with identical specifications. The RC series offers significantly higher inventory availability (13482 units) and active product status. Selection of this substitute is appropriate for applications where AEC-Q200 automotive qualification is not a mandatory requirement.

Automotive-Grade Alternatives: RK73H2BTTD1050F (KOA Speer) and CRCW1206105RFKEA (Vishay Dale)

Both parts maintain AEC-Q200 qualification and are suitable for automotive applications requiring the same environmental and reliability standards as the original part. RK73H2BTTD1050F provides the highest inventory level among automotive-qualified alternatives (13039 units). CRCW1206105RFKEA offers lower inventory but maintains active production status.

Legacy Part (Not Recommended for New Designs): ERJ-8ENF1050V (Panasonic)

This part carries "Not For New Designs" status despite high inventory availability (44001 units). While electrically equivalent and AEC-Q200 qualified, its obsolescence trajectory makes it unsuitable for new product development or long-term supply chain planning.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07105RL replace AC1206FR-07105RL in automotive applications?

A: RC1206FR-07105RL is electrically and mechanically equivalent but lacks AEC-Q200 automotive qualification. It is suitable for non-automotive applications or designs where automotive qualification is not required. For automotive applications requiring AEC-Q200 compliance, use RK73H2BTTD1050F or CRCW1206105RFKEA instead.

Q: Are there physical dimension differences between substitute parts?

A: All parts conform to the 1206 (3216 Metric) package standard. Minor variations exist within standard tolerances: length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), width is 0.063" (1.60mm), and height ranges from 0.024" to 0.028" (0.60mm to 0.70mm). These variations do not affect PCB layout or assembly compatibility.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Both packaging formats contain identical components. Tape & Reel (TR) is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape (CT) is supplied in shorter tape segments for manual handling or lower-volume applications. Packaging format does not affect electrical performance or component specifications.

Q: Why is ERJ-8ENF1050V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and is transitioning the product to end-of-life status. While currently in stock with high availability, future supply cannot be guaranteed. New designs should select from parts with "Active" product status.

Q: Can I use these substitutes interchangeably on the same PCB?

A: Yes. All qualified substitutes are pin-compatible, electrically equivalent, and mechanically compatible with the 1206 package footprint. PCB layout and assembly processes require no modification when substituting between equivalent parts.
