Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-1580-B-T1 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Resistance value: 158 Ohms (exact match required)
• Power rating: 0.125W minimum
• Temperature coefficient: ±5ppm/°C or better
• Operating temperature range: Must support -55°C to 155°C minimum

Mechanical Compatibility Requirements:

• Package type: 0805 (2012 Metric) only
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Regulatory & Quality Requirements:

• Automotive AEC-Q200 qualification
• RoHS3 compliance
• Thin film composition

Substitute parts are grouped into two categories:

Direct Equivalents (Tolerance ±0.1%): Parts with identical tolerance specifications, differing only in packaging format or product status.

Upgraded Alternatives (Tolerance ±0.05% or ±0.02%): Parts with tighter tolerance specifications, providing enhanced precision while maintaining all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Direct Equivalent: RG2012V-1580-B-T5 is the direct functional equivalent to RG2012V-1580-B-T1, maintaining identical electrical specifications (158 Ohms ±0.1%, 0.125W, ±5ppm/°C) and operating temperature range (-55°C ~ 155°C). The part is manufactured by Susumu under active product status and supplied in Tape & Reel packaging format. This substitution requires no circuit redesign and provides identical performance characteristics.

Alternative Manufacturer Option: TNPU0805158RBZEN00 (Vishay Dale) provides direct electrical equivalence with ±0.1% tolerance and identical power rating. This part is AEC-Q200 qualified and RoHS3 compliant. The operating temperature range is -55°C ~ 125°C, which is 30°C lower than the Susumu parts. Selection of this alternative is appropriate only when the application does not require operation above 125°C.

Upgraded Precision Alternatives: RG2012V-1580-W-T1 and RG2012V-1580-W-T5 offer tighter tolerance specifications (±0.05%) while maintaining all other electrical and mechanical parameters. These parts are suitable for applications requiring enhanced precision without modification to circuit design or PCB layout.

Maximum Precision Alternative: RG2012V-1580-P-T1 provides the tightest tolerance specification (±0.02%) available within this product family. This part maintains full compatibility with the original design while delivering superior tolerance performance for precision-critical applications.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-1580-B-T5 be used as a direct replacement for RG2012V-1580-B-T1?

A: Yes. RG2012V-1580-B-T5 is a direct equivalent with identical electrical specifications (158 Ohms ±0.1%, 0.125W, ±5ppm/°C) and operating temperature range (-55°C ~ 155°C). The only difference is packaging format: RG2012V-1580-B-T1 is supplied in bulk, while RG2012V-1580-B-T5 is supplied in Tape & Reel format. Both are manufactured by Susumu and meet AEC-Q200 automotive qualification.

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

A: Both manufacturers provide 158 Ohms ±0.1% thin film resistors in 0805 package with AEC-Q200 qualification. The primary difference is operating temperature range: Susumu RG parts support -55°C ~ 155°C, while Vishay Dale TNPU0805158RBZEN00 supports -55°C ~ 125°C. Selection depends on application temperature requirements.

Q: Can I use RG2012V-1580-W-T1 (±0.05% tolerance) instead of RG2012V-1580-B-T1 (±0.1% tolerance)?

A: Yes. RG2012V-1580-W-T1 provides tighter tolerance (±0.05%) than the original specification (±0.1%), making it a suitable upgrade. All other electrical parameters (158 Ohms, 0.125W, ±5ppm/°C, -55°C ~ 155°C) and mechanical specifications (0805 package) remain identical. No circuit modification is required.

Q: What is the difference between T1 and T5 packaging designations?

A: T1 and T5 designations indicate different Tape & Reel packaging configurations. Both formats are compatible with standard automated assembly equipment. Selection between T1 and T5 depends on production line equipment specifications and tape reel quantity requirements, not electrical performance.

Q: Is RG2012V-1580-P-T1 (±0.02% tolerance) compatible with the original circuit design?

A: Yes. RG2012V-1580-P-T1 maintains all electrical and mechanical specifications of the original part while providing enhanced tolerance performance (±0.02% versus ±0.1%). This part is suitable for direct substitution in applications requiring higher precision without any circuit redesign.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (RG2012V-1580-B-T5, RG2012V-1580-W-T1, RG2012V-1580-W-T5, RG2012V-1580-P-T1, and TNPU0805158RBZEN00) are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can I mix different substitute parts in the same production batch?

A: All substitute parts maintain identical 0805 package dimensions and electrical specifications (158 Ohms, 0.125W, ±5ppm/°C). Parts with different tolerance specifications (±0.1%, ±0.05%, ±0.02%) can be used interchangeably from a mechanical and thermal standpoint. Selection should be based on circuit tolerance requirements and supplier availability.
