Tolerance: ±0.1% or tighter (equal or superior tolerance acceptable)
Composition: Thin Film (electrical performance characteristics)
RoHS3 Compliance (regulatory requirement)
Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)

Acceptable Variation Parameters:

Power rating: Equal or greater than 0.125W (higher ratings provide design margin)

Engineering Selection Recommendations

Direct Equivalent (Same Specifications):

RG2012P-8662-B-T5 (Susumu) is the direct equivalent replacement for the obsolete RG2012P-8662-B-T1. Both parts share identical electrical specifications (86.6 kΩ, ±0.1%, 0.125W, ±25ppm/°C) and mechanical package (0805). The primary difference is packaging format (Tape & Reel vs. bulk), with RG2012P-8662-B-T5 in active production status. This part maintains automotive AEC-Q200 qualification and ROHS3 compliance.

Upgraded Alternatives (Superior Specifications):

RG2012N-8662-B-T5 and RG2012N-8662-W-T1 (Susumu) offer improved temperature coefficient performance (±10ppm/°C vs. ±25ppm/°C) while maintaining all other specifications. RG2012N-8662-W-T1 additionally provides tighter tolerance (±0.05% vs. ±0.1%). Both are active production parts with AEC-Q200 qualification.

RG2012P-8662-W-T5 (Susumu) provides tighter tolerance (±0.05%) with standard temperature coefficient (±25ppm/°C) and maintains full automotive qualification.

Cross-Manufacturer Alternatives:

ERA-6AEB8662V (Panasonic) provides identical electrical and mechanical specifications with AEC-Q200 qualification and active production status. TNPW080586K6BEEA and TNPW080586K6BEEN (Vishay Dale) offer higher power rating (0.26W) and extended temperature range (-55°C to 175°C) with AEC-Q200 qualification, suitable for applications requiring thermal margin.

RT0805BRD0786K6L (YAGEO) matches all electrical specifications with active production status, though without automotive qualification.

Not Recommended for Direct Substitution:

MCU08050D8662BP500 (Vishay Beyschlag) has reduced upper operating temperature limit (125°C vs. 155°C), making it unsuitable for the full temperature range of the original part. 8-2176093-9 (TE Connectivity) has doubled power rating (0.25W) and lacks automotive AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-8662-B-T5 directly replace RG2012P-8662-B-T1?

A: Yes. RG2012P-8662-B-T5 is the direct equivalent with identical electrical specifications (86.6 kΩ, ±0.1%, 0.125W, ±25ppm/°C, -55°C to 155°C) and mechanical package (0805). The difference is packaging format; RG2012P-8662-B-T5 is supplied in Tape & Reel format and is in active production.

Q: What is the difference between RG2012P and RG2012N series?

A: The RG2012N series features improved temperature coefficient (±10ppm/°C) compared to RG2012P (±25ppm/°C). Both series maintain identical resistance, tolerance, power rating, and package specifications. Selection depends on thermal stability requirements.

Q: Can I use TNPW080586K6BEEA as a substitute?

A: Yes, with design considerations. TNPW080586K6BEEA matches the 86.6 kΩ resistance, ±0.1% tolerance, and 0805 package. It provides higher power rating (0.26W vs. 0.125W) and extended temperature range (-55°C to 175°C). The higher power rating provides thermal margin but may affect circuit performance if power dissipation characteristics are critical to design function.

Q: Does the substitute part need AEC-Q200 qualification?

A: AEC-Q200 qualification is required for automotive applications. For non-automotive applications, parts without AEC-Q200 qualification (such as RT0805BRD0786K6L) are electrically compatible. Verify application requirements before selection.

Q: Why is MCU08050D8662BP500 not recommended?

A: MCU08050D8662BP500 has a maximum operating temperature of 125°C, which does not cover the full -55°C to 155°C range of the original part. This creates a functional gap at elevated temperatures and is unsuitable for direct substitution.

Q: Can I use a higher tolerance part (±0.05%) instead of ±0.1%?

A: Yes. Tighter tolerance (±0.05%) is a superior specification and provides better accuracy. Parts such as RG2012N-8662-W-T1 and RG2012P-8662-W-T5 with ±0.05% tolerance are fully compatible and offer improved performance.

Q: What is the significance of the packaging designation (T1 vs. T5)?

A: T1 and T5 designations refer to packaging format. T1 typically indicates bulk or cut-tape packaging, while T5 indicates Tape & Reel format. Both formats contain identical components; the difference is in supply method and handling. Verify packaging requirements for your procurement and assembly processes.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited), matching the original part's environmental compliance specifications.
