AF1206FR-072ML Equivalent & Substitute Parts

Part Overview

The AF1206FR-072ML is a 2 MOhms ±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 and features anti-sulfur properties. The part is currently active in production with 1020 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative manufacturers while maintaining electrical and mechanical compatibility. All substitute parts listed maintain identical electrical specifications and package dimensions within acceptable tolerances.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Resistance value: 2 MOhms
Tolerance: ±1%
Power rating: 0.25W
Package: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
Moisture sensitivity level: 1 (Unlimited)

All listed substitute parts meet these core electrical and mechanical requirements. Variations in physical dimensions (length, width, height) within standard manufacturing tolerances, packaging format (Tape & Reel vs. Cut Tape), and secondary features (anti-sulfur, moisture resistant, high voltage) do not affect functional interchangeability in circuit applications.

Engineering Selection Recommendations

For new designs and production applications, prioritize parts with Active product status and ROHS3 compliance:

AC1206FR-072ML (YAGEO) and CRCW12062M00FKEA (Vishay Dale) are preferred substitutes. Both maintain full AEC-Q200 automotive qualification, ROHS3 compliance, and active production status. AC1206FR-072ML offers higher inventory availability (7249 units) and identical YAGEO manufacturing lineage. CRCW12062M00FKEA provides cross-manufacturer qualification with 24124 units in stock.

KTR18EZPF2004 (Rohm Semiconductor) is suitable for applications requiring high voltage performance while maintaining all core electrical specifications and AEC-Q200 rating.

RC1206FR-072ML (YAGEO) is electrically equivalent but lacks AEC-Q200 automotive certification. Use only in non-automotive applications where automotive qualification is not required.

CRCW12062M00FKTA (Vishay Dale) is not recommended for new designs due to RoHS non-compliance and REACH affected status, despite active production.

ERJ-8ENF2004V (Panasonic) carries "Not For New Designs" status and should be used only for legacy system maintenance or repair applications where design continuity is required.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the AF1206FR-072ML?

A: All listed parts are electrically and mechanically equivalent within the 1206 package footprint. Physical dimension variations (length, width, height) fall within standard manufacturing tolerances and do not affect PCB assembly or circuit performance. Packaging format differences (Tape & Reel vs. Cut Tape) affect only procurement and handling, not functionality.

Q: What is the difference between AC1206FR-072ML and AF1206FR-072ML?

A: Both are YAGEO 1206 2 MOhms ±1% resistors with identical electrical specifications. The primary difference is packaging format: AF uses Tape & Reel, AC uses Cut Tape & Digi-Reel. AC1206FR-072ML features moisture-resistant composition versus AF1206FR-072ML's anti-sulfur properties. Both are AEC-Q200 qualified and ROHS3 compliant.

Q: Why is ERJ-8ENF2004V marked "Not For New Designs"?

A: This designation indicates the part is in mature/legacy phase. While electrically and mechanically equivalent, Panasonic has directed customers toward newer alternatives for new product development. The part remains available for existing design support and maintenance.

Q: Does CRCW12062M00FKTA meet automotive requirements?

A: CRCW12062M00FKTA maintains AEC-Q200 automotive qualification and identical electrical specifications. However, it is RoHS non-compliant and REACH affected, making it unsuitable for applications requiring full regulatory compliance. CRCW12062M00FKEA is the compliant alternative from Vishay Dale.

Q: Are there dimensional differences between manufacturers?

A: Minor variations exist within standard tolerances. YAGEO parts (AF, AC, RC series) specify 0.122" L × 0.063" W. Vishay Dale (CRCW series) and Rohm (KTR series) specify 0.126" L × 0.063" W. Panasonic (ERJ-8EN) specifies 0.126" L × 0.063" W. These differences are within PCB design tolerances and do not affect assembly or performance.

Q: Which substitute offers the best inventory availability?

A: RC1206FR-072ML provides the highest stock level at 1,000,100 units. For active automotive designs, AC1206FR-072ML (7,249 units) and CRCW12062M00FKEA (24,124 units) offer strong availability with full compliance certifications.
