Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-3650-B-T1 is determined by the following critical parameters:

Electrical Parameters:

• Resistance value: 365 Ohms (exact match required)
• Power rating: 0.125W minimum
• Temperature coefficient: ±5ppm/°C or better
• Operating temperature range: Must support -55°C ~ 155°C minimum

Mechanical Parameters:

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

Compliance & Certification:

• Automotive AEC-Q200 qualification
• RoHS3 compliance
• Thin film composition
• Anti-sulfur construction

Tolerance Considerations: Substitute parts with equal or tighter tolerance specifications (lower tolerance values) are direct functional equivalents. Parts with ±0.1% tolerance match the original specification exactly. Parts with ±0.05% or ±0.02% tolerance provide enhanced precision and are classified as upgrades.

Packaging Format: The original part RG2012V-3650-B-T1 is supplied in bulk packaging. Substitute parts with Tape & Reel (TR) packaging provide identical electrical and mechanical performance with alternative distribution format.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance):

RG2012V-3650-B-T5 is the direct equivalent to RG2012V-3650-B-T1. Both parts share identical electrical specifications (365 Ohms ±0.1% tolerance, 0.125W power rating, ±5ppm/°C temperature coefficient, -55°C ~ 155°C operating range). The primary difference is packaging format: RG2012V-3650-B-T5 is supplied in Tape & Reel format versus bulk packaging. RG2012V-3650-B-T5 carries Active product status, ensuring continued availability and manufacturing support.

Precision Upgrades (Tighter Tolerance):

RG2012V-3650-W-T1 and RG2012V-3650-W-T5 provide ±0.05% tolerance, representing a 2x improvement in tolerance specification compared to the original ±0.1%. Both maintain identical power rating, temperature coefficient, and operating temperature range. These parts are suitable for applications requiring enhanced precision without modification to circuit design. Both carry Active product status.

RG2012V-3650-P-T1 provides ±0.02% tolerance, representing a 5x improvement in tolerance specification. This part is suitable for high-precision measurement and calibration circuits. Active product status ensures availability.

Cross-Manufacturer Alternative:

TNPU0805365RBZEN00 (Vishay Dale) is a cross-manufacturer substitute with matching 365 Ohms ±0.1% specification and 0.125W power rating. This part includes moisture-resistant construction in addition to anti-sulfur features. Operating temperature range is -55°C ~ 125°C, which is 30°C narrower than the Susumu parts. TNPU0805365RBZEN00 carries Active product status and full AEC-Q200 qualification. Use this part only when the reduced upper temperature limit (-125°C maximum versus -155°C) is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-3650-B-T5 be used as a direct replacement for RG2012V-3650-B-T1?

A: Yes. RG2012V-3650-B-T5 is electrically and mechanically identical to RG2012V-3650-B-T1. The only difference is packaging format (Tape & Reel versus bulk). Both parts have 365 Ohms ±0.1% resistance, 0.125W power rating, and identical temperature characteristics. RG2012V-3650-B-T5 is Active status, making it the recommended replacement for the Obsolete RG2012V-3650-B-T1.

Q: What is the difference between RG2012V-3650-B-T1 and RG2012V-3650-W-T1?

A: The primary difference is tolerance specification. RG2012V-3650-B-T1 has ±0.1% tolerance, while RG2012V-3650-W-T1 has ±0.05% tolerance. Both parts have identical 365 Ohms resistance, 0.125W power rating, and operating temperature range (-55°C ~ 155°C). RG2012V-3650-W-T1 provides tighter tolerance for precision applications. Both are 0805 package, thin film, anti-sulfur, AEC-Q200 qualified.

Q: Can I use RG2012V-3650-P-T1 in place of RG2012V-3650-B-T1?

A: Yes. RG2012V-3650-P-T1 has ±0.02% tolerance, which is tighter than the original ±0.1% specification. All other electrical parameters are identical: 365 Ohms resistance, 0.125W power rating, ±5ppm/°C temperature coefficient, -55°C ~ 155°C operating range. RG2012V-3650-P-T1 is suitable for applications requiring higher precision. No circuit modifications are required.

Q: What is the operating temperature difference between Susumu and Vishay Dale parts?

A: Susumu RG series parts (RG2012V-3650-B-T1, RG2012V-3650-B-T5, RG2012V-3650-W-T1, RG2012V-3650-W-T5, RG2012V-3650-P-T1) operate from -55°C to 155°C. The Vishay Dale TNPU0805365RBZEN00 operates from -55°C to 125°C. The Vishay part has a 30°C lower maximum operating temperature. Verify application requirements before selecting the Vishay alternative.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (RG2012V-3650-B-T5, RG2012V-3650-W-T1, RG2012V-3650-W-T5, RG2012V-3650-P-T1, and TNPU0805365RBZEN00) are RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All parts are AEC-Q200 qualified for automotive applications.

Q: What does the "T1" and "T5" designation mean in Susumu part numbers?

A: The suffix indicates packaging format. "T1" denotes Tape & Reel (TR) packaging. "T5" also denotes Tape & Reel packaging. The original RG2012V-3650-B-T1 uses bulk packaging (no TR designation in the original specification). Both T1 and T5 variants are supplied in Tape & Reel format for automated assembly processes.

Q: Can I mix different tolerance grades in the same circuit?

A: Yes, provided circuit design tolerances accommodate the variation. If the original design used ±0.1% parts, substituting with ±0.05% or ±0.02% parts will not degrade performance. However, substituting tighter tolerance parts with looser tolerance parts requires circuit analysis to confirm acceptable performance margins.

Q: Is TNPU0805365RBZEN00 suitable for automotive applications?

A: Yes. TNPU0805365RBZEN00 carries AEC-Q200 qualification and anti-sulfur construction, meeting automotive reliability standards. The moisture-resistant feature provides additional environmental protection. Verify that the -55°C ~ 125°C operating range meets application requirements before selection.
