AC2010FK-0771K5L Equivalent & Substitute Parts

Part Overview

The AC2010FK-0771K5L is a 71.5 kOhms ±1% 0.75W thick film chip resistor in 2010 (5025 Metric) package manufactured by YAGEO. This component is rated for automotive applications under AEC-Q200 standard with moisture-resistant construction and operates across -55°C to 155°C. The part is currently in active production status with 818 units in stock.

Substitute parts are necessary when the primary manufacturer experiences supply constraints, when design requirements call for alternative qualified suppliers, or when inventory availability necessitates cross-manufacturer sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the AC2010FK-0771K5L is determined by strict equivalence across the following parameters:

• Resistance value: 71.5 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.75W (exact match required)
• Package: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• AEC-Q200 automotive qualification (required for automotive applications)
• RoHS3 compliance (required for regulatory conformance)
• Moisture Sensitivity Level 1 (required for reliability in moisture-prone environments)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the primary part number.

Parameter Comparison

Engineering Selection Recommendations

RK73H2HTTE7152F (KOA Speer Electronics) is the primary recommended substitute. This part maintains active production status, carries identical AEC-Q200 automotive qualification, includes moisture-resistant construction matching the original specification, and offers the highest inventory availability at 3763 units. The maximum seated height of 0.028" (0.70mm) represents a 0.002" increase over the primary part but remains within typical PCB layout tolerances for 2010 package components.

ERJ-12SF7152U (Panasonic) is available as a secondary option with 2248 units in stock. However, this part carries a "Not For New Designs" product status designation, indicating that Panasonic has discontinued active development and support for this series. While electrically and mechanically equivalent, this part should be selected only when primary and recommended alternatives are unavailable. Additionally, this part does not include moisture-resistant construction, which may impact long-term reliability in high-humidity automotive environments despite maintaining MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can RK73H2HTTE7152F be used as a direct replacement for AC2010FK-0771K5L?

A: Yes. Both parts share identical electrical specifications (71.5 kOhms ±1%, 0.75W, ±100ppm/°C, -55°C to 155°C), identical package geometry (2010/5025 Metric), and equivalent automotive qualifications (AEC-Q200, RoHS3, MSL 1). The 0.002" difference in seated height is within standard PCB design tolerances for this package class.

Q: Why is ERJ-12SF7152U marked "Not For New Designs"?

A: This designation indicates that Panasonic has transitioned this product line to end-of-life status and is no longer actively developing or supporting new applications. While existing inventory remains available and the part meets all electrical and mechanical requirements, Panasonic recommends using alternative suppliers for new circuit designs to ensure long-term supply chain stability.

Q: Are there any moisture-related differences between these substitutes?

A: AC2010FK-0771K5L and RK73H2HTTE7152F both specify moisture-resistant construction. ERJ-12SF7152U does not include this feature in its specification, though all three parts maintain MSL 1 (Unlimited) rating. For applications requiring explicit moisture resistance, AC2010FK-0771K5L or RK73H2HTTE7152F are preferred.

Q: What is the significance of the 0.002" height difference?

A: The AC2010FK-0771K5L has a maximum seated height of 0.026" (0.65mm), while both substitute parts measure 0.028" (0.70mm). This 0.002" difference is negligible for standard PCB assembly and does not affect component placement, soldering, or circuit performance. Verify clearance only in applications with height-constrained layouts.

Q: Can these parts be intermixed in the same production batch?

A: Yes, provided your quality and traceability procedures permit cross-manufacturer sourcing. All three parts meet identical electrical, mechanical, and automotive specifications. Document the manufacturer and part number for each component in production records to maintain traceability and support field service requirements.
