Engineering Selection Recommendations

Susumu RG Series Substitutes (Same Manufacturer):

The RG2012N and RG2012V series variants provide direct substitution with enhanced electrical specifications. All listed Susumu alternatives are active products with ROHS3 compliance and AEC-Q200 automotive qualification identical to the original part.

RG2012N-1691-B-T5 and RG2012N-1691-W-T5 maintain the ±10ppm/°C temperature coefficient of the original while offering improved tolerance (±0.1% and ±0.05% respectively). These parts are suitable for applications where the original tolerance specification is acceptable but improved accuracy is beneficial.

RG2012V series variants (RG2012V-1691-B-T5, RG2012V-1691-P-T1, RG2012V-1691-W-T1, RG2012V-1691-W-T5) provide superior temperature stability with ±5ppm/°C coefficient. The RG2012V-1691-P-T1 offers the tightest tolerance at ±0.02%, suitable for precision circuit applications requiring minimal resistance drift.

Cross-Manufacturer Substitute (Vishay Dale):

The TNPW08051K69BYEA from Vishay Dale provides electrical equivalence with enhanced power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). This part carries identical AEC-Q200 qualification and anti-sulfur construction. The higher power rating provides additional thermal margin in applications subject to power dissipation stress.

Selection Criteria:

Choose Susumu RG2012N variants for direct specification replacement with improved tolerance. Select Susumu RG2012V variants when temperature stability is critical to circuit performance. Specify TNPW08051K69BYEA when higher power dissipation capability or extended temperature range is required by the application.

Frequently Asked Questions (FAQ)

Q: Can RG2012V series parts directly replace RG2012N series parts?

A: Yes. Both series maintain identical resistance value (1.69 kOhms), package (0805), power rating (0.125W), and AEC-Q200 automotive qualification. RG2012V variants offer improved temperature coefficient (±5ppm/°C versus ±10ppm/°C), making them suitable for applications requiring enhanced thermal stability.

Q: What is the difference between tolerance grades (±0.25%, ±0.1%, ±0.05%, ±0.02%)?

A: Tolerance specifies the maximum allowable deviation from the nominal 1.69 kOhms resistance value. Tighter tolerance (lower percentage) indicates higher accuracy. ±0.25% allows deviation up to ±4.225 Ohms, while ±0.02% allows only ±0.338 Ohms. Selection depends on circuit accuracy requirements.

Q: Is the TNPW08051K69BYEA from Vishay Dale mechanically compatible with the original Susumu part?

A: Yes. Both components use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). PCB layout and assembly processes require no modification.

Q: Why does the TNPW08051K69BYEA have higher power rating (0.26W) than the original (0.125W)?

A: The Vishay Dale part is designed for higher power dissipation applications. The increased power rating does not affect electrical performance in circuits designed for 0.125W operation. This provides additional thermal margin and reliability in power-sensitive applications.

Q: Are all substitute parts ROHS3 compliant and AEC-Q200 qualified?

A: Yes. All listed substitute parts carry ROHS3 compliance and AEC-Q200 automotive qualification, matching the original RG2012N-1691-C-T5 specifications.

Q: What is the significance of the temperature coefficient specification?

A: Temperature coefficient (ppm/°C) indicates how much the resistance value changes with temperature. Lower values indicate better stability. RG2012V series parts with ±5ppm/°C provide superior performance in temperature-sensitive applications compared to RG2012N series with ±10ppm/°C.

Q: Can I use RG2012N-1691-W-T5 and RG2012N-1691-W-T1 interchangeably?

A: Yes. Both parts are electrically identical (1.69 kOhms ±0.05%, 0.125W, ±10ppm/°C). The T5 and T1 designations indicate different tape reel specifications for automated assembly. Selection depends on your procurement and assembly equipment compatibility.

Q: Is the original RG2012N-1691-C-T5 still available for new designs?

A: No. The RG2012N-1691-C-T5 is classified as obsolete. For new designs and production, select from the active substitute parts listed. RG2012N-1691-B-T5 and RG2012N-1691-W-T5 provide the closest specification match with improved tolerance and active product status.
