Substitute Part Grouping Explanation

Substitute parts are categorized into Upgrade and Direct groups based on the following parameters:

Resistance value: 1.02 kOhms (exact match required)
Package size: 0805 (2012 Metric)
Composition: Thin Film
Operating temperature range: -55°C ~ 155°C
Features: Anti-Sulfur, Automotive AEC-Q200 compliance

Upgrade substitutes offer improved tolerance (±0.1%, ±0.05%, ±0.02%) or temperature coefficient (±10ppm/°C, ±5ppm/°C) compared to the original ±0.25% tolerance and ±25ppm/°C specification. All upgrade parts are from the same Susumu RG series and maintain identical package dimensions and power rating.

Direct substitutes match or exceed the electrical specifications with the same or better tolerance and temperature coefficient, from manufacturers including TE Connectivity Passive Product and YAGEO.

Engineering Selection Recommendations

For form-fit-function replacement: RG2012P-1021-B-T5 and RT0805CRD071K02L match the original temperature coefficient (±25ppm/°C) and power rating (0.125W). RG2012P-1021-B-T5 offers improved tolerance (±0.1%) while RT0805CRD071K02L matches the original ±0.25% tolerance.

For automotive applications: All Susumu RG series substitutes include Anti-Sulfur and Automotive AEC-Q200 features. Select based on required tolerance and temperature coefficient performance.

For higher power capability: 1-2176092-9 provides 0.25W power rating, double the original 0.125W specification.

For precision applications: RG2012V-1021-P-T1 offers ±0.02% tolerance with ±5ppm/°C temperature coefficient for high-accuracy circuits.

All substitute parts are ROHS3 compliant, have Moisture Sensitivity Level 1 (Unlimited), and maintain the same 0805 (2012 Metric) footprint with 0.079" L x 0.049" W dimensions.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts pin-compatible with RG2012P-1021-C-T5?
A: All substitutes use the 0805 (2012 Metric) package with identical dimensions (2.00mm x 1.25mm). Height varies between 0.020" (0.50mm) for Susumu parts and 0.024-0.026" for other manufacturers.

Q: Can I use a substitute with tighter tolerance than the original ±0.25%?
A: Tighter tolerance (±0.1%, ±0.05%, ±0.02%) provides equal or better performance. Circuit functionality designed for ±0.25% tolerance will operate correctly with tighter tolerance parts.

Q: What is the difference between RG2012N, RG2012P, and RG2012V series?
A: The suffix indicates temperature coefficient performance: RG2012P (±25ppm/°C), RG2012N (±10ppm/°C), RG2012V (±5ppm/°C). All maintain the same resistance value, package, and automotive features.

Q: Do all substitutes support automotive applications?
A: All Susumu RG series parts include Anti-Sulfur and Automotive AEC-Q200 features. 1-2176092-9 and RT0805CRD071K02L do not specify automotive features.

Q: What is the impact of using a 0.25W part instead of 0.125W?
A: 1-2176092-9 offers higher power dissipation capability. It is compatible for applications designed for 0.125W but provides additional thermal margin.
