RG2012V-1910-B-T1 Equivalent & Substitute Parts

Part Overview

The RG2012V-1910-B-T1 is a 191 Ohms ±0.1% thin film chip resistor in 0805 (2012 Metric) package rated for 0.125W (1/8W) power dissipation. This component features anti-sulfur construction and meets Automotive AEC-Q200 qualification standards. The part is classified as Obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement continuity. Suitable alternatives maintain the same resistance value, package form factor, and automotive-grade specifications while offering either equivalent or enhanced tolerance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012V-1910-B-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 191 Ohms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Automotive rating: AEC-Q200
• Temperature coefficient: ±5ppm/°C
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Tolerance: Equal or tighter (±0.1% or better)
• Operating temperature range: Equal or extended
• Packaging format: Tape & Reel (TR) acceptable for bulk procurement
• Manufacturer: Alternative qualified suppliers permitted

Substitute parts are grouped into two categories: Direct equivalents maintaining ±0.1% tolerance, and upgraded alternatives offering tighter tolerance specifications (±0.05% or ±0.02%) while maintaining all other electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Substitutes (Same Tolerance):

RG2012V-1910-B-T5 and TNPU0805191RBZEN00 are direct functional equivalents to the RG2012V-1910-B-T1, maintaining ±0.1% tolerance specification. Both parts are Active status components with full AEC-Q200 automotive qualification. RG2012V-1910-B-T5 is supplied in Tape & Reel format by Susumu and maintains the full -55°C to 155°C operating range. TNPU0805191RBZEN00 is supplied by Vishay Dale in Tape & Reel format with operating range limited to -55°C to 125°C; this part includes moisture-resistant construction as an additional feature.

Upgraded Tolerance Substitutes:

RG2012V-1910-P-T1 offers ±0.02% tolerance, providing tighter resistance accuracy than the original specification. RG2012V-1910-W-T1 and RG2012V-1910-W-T5 offer ±0.05% tolerance, intermediate between the original and highest-grade option. All three upgraded alternatives are Active status Susumu components with full AEC-Q200 qualification and -55°C to 155°C operating range. These parts are suitable for applications requiring enhanced precision without modification to circuit design or thermal management.

Selection between direct equivalents and upgraded alternatives depends on application tolerance requirements. All substitute parts maintain identical mechanical fit, electrical performance envelope, and automotive compliance characteristics.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-1910-B-T5 be used as a direct replacement for RG2012V-1910-B-T1?

A: Yes. Both parts share identical electrical specifications (191 Ohms ±0.1%, 0.125W, ±5ppm/°C), package form factor (0805), and automotive qualification (AEC-Q200). The primary difference is packaging format: RG2012V-1910-B-T5 is supplied in Tape & Reel format suitable for automated assembly, while the original uses bulk packaging. Mechanical fit and electrical performance are equivalent.

Q: What is the difference between the Susumu RG series and Vishay Dale TNPU series substitutes?

A: Both manufacturers provide 191 Ohms ±0.1% thin film resistors in 0805 package with AEC-Q200 rating. The TNPU0805191RBZEN00 includes moisture-resistant construction and is limited to -55°C to 125°C operating range, compared to the RG series -55°C to 155°C range. For applications operating above 125°C, Susumu RG series parts are required.

Q: Are the upgraded tolerance parts (±0.05% and ±0.02%) compatible with existing circuit designs?

A: Yes. Upgraded tolerance parts maintain all electrical and mechanical parameters of the original specification. Tighter tolerance provides enhanced accuracy without requiring circuit redesign. These parts are suitable for direct substitution in applications where improved precision is beneficial or required.

Q: What is the significance of the T1 and T5 suffixes in Susumu part numbers?

A: The T1 and T5 suffixes indicate packaging format. T1 denotes bulk packaging, while T5 denotes Tape & Reel (TR) format. Electrical specifications, tolerance, and performance characteristics are identical between T1 and T5 variants of the same base part number.

Q: Is the TNPU0805191RBZEN00 suitable for high-temperature automotive applications?

A: The TNPU0805191RBZEN00 operates to 125°C maximum. For applications requiring operation to 155°C, Susumu RG2012V-1910 series parts (B-T1, B-T5, P-T1, W-T1, W-T5) are required, as these maintain the full -55°C to 155°C operating range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, matching the original RG2012V-1910-B-T1 specification.
