AC1206FR-0782K5L Equivalent & Substitute Parts

Part Overview

The AC1206FR-0782K5L is a 82.5 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by YAGEO. This component is rated for automotive applications under AEC-Q200 standard with moisture resistance and operates across -55°C to 155°C. The part is currently active in production with 758 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when design requirements mandate alternative manufacturers for supply chain resilience, or when specific certifications or feature sets align better with application requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the AC1206FR-0782K5L is determined by strict equivalence across the following parameters:

Resistance value: 82.5 kOhms
Tolerance: ±1%
Power rating: 0.25W
Package: 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
MSL rating: 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical specifications. Variations in physical dimensions (length, width, height) and manufacturer-specific features (such as AEC-Q200 automotive rating) are noted but do not disqualify substitution when the primary parameters align.

Engineering Selection Recommendations

For new designs, prioritize parts with Active product status and AEC-Q200 automotive certification when the application requires automotive-grade reliability. The following parts meet both criteria:

RK73H2BTTD8252F (KOA Speer Electronics, Inc.) — 25,510 units available
CRCW120682K5FKEA (Vishay Dale) — 22,573 units available
RMCF1206FT82K5 (Stackpole Electronics Inc) — 6,764 units available

For applications where AEC-Q200 certification is not required, RC1206FR-0782K5L (YAGEO) offers the highest inventory availability at 166,432 units and maintains Active status.

The ERJ-8ENF8252V (Panasonic Electronic Components) carries AEC-Q200 certification and substantial inventory (52,710 units) but is marked "Not For New Designs" and should be used only for legacy system maintenance or repair applications.

All listed substitutes maintain ROHS3 compliance, MSL 1 rating, and identical electrical specifications to the primary part.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1206FR-0782K5L for AC1206FR-0782K5L in an automotive application?

A: RC1206FR-0782K5L matches all core electrical and mechanical parameters but lacks AEC-Q200 automotive certification. Use only in non-automotive applications or where automotive qualification is not required.

Q: What is the difference between parts with and without AEC-Q200 rating?

A: AEC-Q200 certification indicates the part meets automotive industry reliability and quality standards. Parts without this rating are suitable for general industrial and consumer applications but should not be used in automotive designs requiring compliance.

Q: Are all substitute parts pin-compatible with the original AC1206FR-0782K5L?

A: Yes. All listed substitutes use the same 1206 (3216 Metric) package with 2 terminations and identical footprint requirements for PCB layout.

Q: Why do some substitutes have slightly different physical dimensions?

A: Manufacturer tolerances result in minor variations in length, width, and height within acceptable limits. These variations do not affect electrical performance or PCB assembly compatibility for the 1206 package.

Q: Should I use ERJ-8ENF8252V for new designs?

A: No. ERJ-8ENF8252V is marked "Not For New Designs" by Panasonic. Use this part only for repair or maintenance of existing systems. For new designs, select from parts with Active status.

Q: Which substitute offers the best supply availability?

A: RC1206FR-0782K5L (YAGEO) provides the highest inventory at 166,432 units. If AEC-Q200 certification is required, RK73H2BTTD8252F (KOA Speer) offers 25,510 units.
