Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012V-2371-B-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.37 kOhms
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Automotive AEC-Q200 qualification
• Anti-Sulfur feature

Allowable Variation Parameters:

• Tolerance: Can be equal or tighter (±0.1%, ±0.05%, ±0.02%)
• Temperature Coefficient: ±5ppm/°C (consistent across all substitutes)
• Operating Temperature Range: -55°C minimum required; upper limit may vary
• Packaging format: Tube or Tape & Reel (TR)
• Product Status: Active substitutes preferred over obsolete

All substitute parts listed maintain identical electrical performance within the specified tolerance bands and meet or exceed the original part's environmental and automotive qualification requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Tolerance):

RG2012V-2371-B-T5 and TNPU08052K37BZEN00 are direct functional equivalents to the RG2012V-2371-B-T1, maintaining the same ±0.1% tolerance specification. Both parts are active products with full AEC-Q200 automotive qualification and anti-sulfur construction. RG2012V-2371-B-T5 is a Susumu product with identical operating temperature range (-55°C ~ 155°C). TNPU08052K37BZEN00 is a Vishay Dale alternative with a reduced upper operating temperature limit of 125°C, suitable for applications not requiring the full 155°C maximum.

Upgraded Tolerance Substitutes:

RG2012V-2371-W-T1, RG2012V-2371-W-T5, and RG2012V-2371-P-T1 offer tighter tolerance specifications (±0.05% and ±0.02% respectively) while maintaining all other electrical and environmental parameters. These parts are active Susumu products suitable for precision circuit applications requiring enhanced accuracy. The tolerance improvement does not affect mechanical compatibility or thermal performance.

Product Status Consideration:

All substitute parts listed carry active product status, providing long-term availability and supply chain stability compared to the obsolete RG2012V-2371-B-T1. Selection should prioritize active products for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-2371-B-T5 replace RG2012V-2371-B-T1 in existing designs?

A: Yes. RG2012V-2371-B-T5 is a direct substitute with identical electrical specifications (2.37 kOhms ±0.1%, 0.125W), package (0805), composition (thin film), and automotive qualifications (AEC-Q200, anti-sulfur). The primary difference is packaging format (Tape & Reel versus Tube) and active product status. Electrical performance and mechanical fit are equivalent.

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

A: Both manufacturers provide 2.37 kOhms ±0.1% thin film resistors in 0805 package with AEC-Q200 qualification and anti-sulfur features. The Vishay Dale TNPU08052K37BZEN00 includes moisture-resistant construction and operates to 125°C maximum, compared to 155°C for Susumu parts. Selection depends on application temperature requirements and supplier availability.

Q: Are the tighter tolerance variants (±0.05%, ±0.02%) pin-compatible with the original part?

A: Yes. RG2012V-2371-W-T1, RG2012V-2371-W-T5, and RG2012V-2371-P-T1 maintain identical 0805 package dimensions and two-terminal configuration. Tighter tolerance specifications do not affect mechanical fit or PCB layout. These parts are direct upgrades for applications requiring enhanced accuracy.

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

A: The T1 and T5 suffixes indicate packaging format. T1 denotes Tube packaging, while T5 denotes Tape & Reel (TR) packaging. Both formats contain identical components; the difference is in delivery and handling method. Electrical specifications remain unchanged.

Q: Can I use TNPU08052K37BZEN00 in applications requiring operation above 125°C?

A: No. The Vishay Dale TNPU08052K37BZEN00 is rated for -55°C to 125°C operating temperature. Applications requiring operation to 155°C must use Susumu RG series parts (RG2012V-2371-B-T5, RG2012V-2371-W-T1, RG2012V-2371-W-T5, or RG2012V-2371-P-T1).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the environmental compliance status of the original RG2012V-2371-B-T1.
