RG2012N-751-C-T5 Equivalent & Substitute Parts

Part Overview

The RG2012N-751-C-T5 is a 750 Ohm ±0.25% thin film chip resistor in 0805 (2012 Metric) package rated for 0.125W (1/8W) power dissipation. Manufactured by Susumu, this component features anti-sulfur coating and automotive AEC-Q200 qualification, suitable for high-reliability applications in harsh environments. The part is currently obsolete, necessitating identification of functionally equivalent active alternatives that maintain electrical and mechanical compatibility while meeting automotive and industrial standards.

Substitute Part Grouping Explanation

Substitution of the RG2012N-751-C-T5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

Resistance value: 750 Ohms (exact match required)
Package type: 0805 (2012 Metric) (exact match required)
Power rating: Minimum 0.125W (1/8W)
Composition: Thin film technology
Operating temperature range: Minimum -55°C to 155°C coverage
Compliance: ROHS3 and AEC-Q200 certification

Tolerance Consideration: The original part specifies ±0.25% tolerance. Substitute parts with equal or tighter tolerance (±0.1%, ±0.05%, ±0.02%) are electrically compatible and represent upgrades in precision. Parts with looser tolerance are not suitable substitutes.

Temperature Coefficient: The original part specifies ±10ppm/°C. Substitute parts with equal or lower temperature coefficient (±5ppm/°C) provide improved stability. Parts with higher temperature coefficient are not suitable substitutes.

All identified substitute parts maintain the 0805 package footprint, thin film construction, and automotive-grade qualification required for direct replacement in existing designs.

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series - Same Manufacturer):

The Susumu RG2012N and RG2012V series parts provide direct functional replacement with improved or equivalent specifications. RG2012N-751-B-T5, RG2012N-751-W-T1, and RG2012N-751-W-T5 maintain the ±10ppm/°C temperature coefficient of the original part while offering tighter tolerance specifications. These parts are active products with full AEC-Q200 automotive qualification and anti-sulfur coating.

The RG2012V series variants (RG2012V-751-B-T5, RG2012V-751-P-T1, RG2012V-751-W-T1, RG2012V-751-W-T5) provide enhanced performance with ±5ppm/°C temperature coefficient, representing superior stability characteristics while maintaining all other critical parameters and automotive compliance.

Secondary Substitute (YAGEO RT0805WRB07750RL):

The YAGEO RT0805WRB07750RL offers electrical compatibility with ±0.05% tolerance and identical power rating. However, this part lacks AEC-Q200 automotive qualification and anti-sulfur coating. Selection of this part is appropriate only for non-automotive applications where automotive-grade certification is not required.

Higher Power Alternative (Vishay Dale TNPW0805750RBYEA):

The TNPW0805750RBYEA provides 0.26W power rating, exceeding the original 0.125W specification, with extended operating temperature range to 175°C. This part maintains AEC-Q200 qualification, anti-sulfur coating, and moisture resistance. The increased power rating and temperature range make this suitable for applications requiring enhanced thermal margin or higher temperature operation.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with tighter tolerance than the original RG2012N-751-C-T5?

A: Yes. Substitute parts with tolerance specifications of ±0.1%, ±0.05%, or ±0.02% are electrically compatible with the original ±0.25% specification. Tighter tolerance represents improved precision and is functionally acceptable in all applications where the original part was specified.

Q: What is the difference between RG2012N and RG2012V series parts?

A: Both series are thin film 0805 package resistors with identical mechanical dimensions and power ratings. The primary difference is temperature coefficient: RG2012N series specifies ±10ppm/°C while RG2012V series specifies ±5ppm/°C. The RG2012V series provides superior temperature stability.

Q: Is the YAGEO RT0805WRB07750RL suitable for automotive applications?

A: The YAGEO RT0805WRB07750RL is not AEC-Q200 qualified and lacks anti-sulfur coating. This part is suitable only for non-automotive applications. For automotive or harsh environment applications, select from the Susumu RG series or Vishay Dale TNPW series alternatives.

Q: Can I substitute the TNPW0805750RBYEA for the original RG2012N-751-C-T5?

A: Yes. The TNPW0805750RBYEA is mechanically and electrically compatible with identical 0805 package footprint, 750 Ohm resistance, and AEC-Q200 qualification. The higher power rating (0.26W versus 0.125W) and extended temperature range (to 175°C) provide additional design margin. Physical height differs slightly (0.55mm maximum versus 0.50mm maximum), which may require verification in space-constrained layouts.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance, matching the environmental compliance status of the original RG2012N-751-C-T5.

Q: What is the moisture sensitivity level for all substitute parts?

A: All substitute parts specify MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. This matches the original part specification.

Q: Can I use substitute parts with different packaging (Tape & Reel versus bulk)?

A: The substitute parts listed are specified in Tape & Reel (TR) packaging. Packaging format does not affect electrical or mechanical compatibility. Verify packaging availability with your supplier based on procurement requirements.
