AF1210FR-071ML Equivalent & Substitute Parts

Part Overview

The AF1210FR-071ML is a 1 MOhms ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by YAGEO. This component features anti-sulfur properties and automotive AEC-Q200 qualification, making it suitable for automotive and harsh environment applications. The part is currently active in production with 738 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility across qualified manufacturers is needed while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AF1210FR-071ML is determined by strict equivalence across the following parameters:

• Resistance value: 1 MOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package designation: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical requirements. Variations in physical dimensions (length, width, height) within the 1210 package specification and differences in secondary features (anti-sulfur vs. moisture resistant) do not affect functional substitutability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, RC1210FR-071ML (YAGEO) and CRCW12101M00FKEA (Vishay Dale) are primary substitutes. Both parts are active in production and carry full automotive certification.

RC1210FR-071ML offers the highest inventory availability (14,301 units) and maintains YAGEO series continuity, making it the preferred substitute when supply of the AF1210FR-071ML is constrained.

CRCW12101M00FKEA provides cross-manufacturer qualification through Vishay Dale and represents the largest available inventory (18,265 units), suitable for high-volume applications requiring supply chain diversification.

ERJ-14NF1004U (Panasonic) meets all electrical and mechanical specifications and carries AEC-Q200 certification. However, its "Not For New Designs" status indicates this part is in end-of-life phase. Use of this substitute should be limited to legacy design maintenance or when other options are unavailable.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-071ML directly replace AF1210FR-071ML in automotive applications?

A: Yes. Both parts are YAGEO 1210 package resistors with identical electrical specifications (1 MOhms ±1%, 0.5W, ±100ppm/°C, -55°C to 155°C). The primary difference is the feature set: AF1210FR-071ML includes anti-sulfur treatment while RC1210FR-071ML is moisture resistant. Both are AEC-Q200 qualified and ROHS3 compliant.

Q: Are there physical dimension differences between these substitutes?

A: Minor variations exist within the 1210 package specification. AF1210FR-071ML and RC1210FR-071ML measure 3.10mm × 2.60mm with 0.60mm maximum height. CRCW12101M00FKEA and ERJ-14NF1004U measure 3.20mm × 2.50mm with 0.60mm and 0.70mm maximum heights respectively. These variations remain within standard 1210 package tolerances and do not affect PCB layout or circuit performance.

Q: Should ERJ-14NF1004U be used for new designs?

A: No. ERJ-14NF1004U carries a "Not For New Designs" status, indicating Panasonic has discontinued active development of this part. It remains suitable for legacy design support and maintenance applications only.

Q: What is the difference between anti-sulfur and moisture resistant features?

A: Anti-sulfur treatment (AF series) protects against sulfur-containing environmental contaminants common in industrial and automotive settings. Moisture resistant treatment (RC series) provides protection against humidity and moisture ingress. Both features are secondary to the core electrical specifications and do not affect substitutability in standard circuit applications.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitutes—RC1210FR-071ML, CRCW12101M00FKEA, and ERJ-14NF1004U—are ROHS3 compliant with MSL rating 1 (Unlimited), matching the AF1210FR-071ML specification.
