RG2012P-8252-C-T5 Equivalent & Substitute Parts

Part Overview

The RG2012P-8252-C-T5 is an 82.5 kOhms ±0.25% thin film chip resistor in 0805 (2012 Metric) package rated for 0.125W (1/8W) power dissipation. Manufactured by Susumu, this component features anti-sulfur coating and automotive AEC-Q200 qualification, suitable for high-reliability applications across -55°C to 155°C operating temperature range.

The RG2012P-8252-C-T5 is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs and field replacements. Substitute components must maintain electrical compatibility while meeting or exceeding the original specifications.

Substitute Part Grouping Explanation

Substitution of the RG2012P-8252-C-T5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

Resistance value: 82.5 kOhms (exact match required)
Package type: 0805 (2012 Metric) (exact match required)
Power rating: 0.125W minimum (equal or higher acceptable)
Composition: Thin Film (exact match required)
Operating temperature range: -55°C to 155°C minimum (equal or wider acceptable)

Tolerance Consideration: The original part specifies ±0.25% tolerance. Substitute parts with equal or tighter tolerance (±0.1%, ±0.05%) are direct upgrades and provide improved circuit performance. Parts with looser tolerance are not acceptable substitutes.

Automotive Qualification: The original part carries AEC-Q200 automotive qualification. Substitute parts may include AEC-Q200 qualified components (preferred for automotive applications) or non-qualified alternatives depending on application requirements.

Temperature Coefficient: The original part specifies ±25ppm/°C. Substitute parts with equal or lower temperature coefficient values provide improved stability.

Substitute parts are grouped into two categories:

Upgrade Substitutes: Active production parts with tighter tolerance (±0.1% or ±0.05%), improved temperature coefficient, or enhanced automotive qualification. These provide superior performance characteristics.

Direct Substitutes: Active production parts with equivalent or superior specifications that maintain functional compatibility without performance enhancement.

Engineering Selection Recommendations

Primary Recommendation - Susumu RG Series (Same Manufacturer):

The Susumu RG2012N-8252-B-T5 and RG2012P-8252-B-T5 are preferred substitutes as they maintain manufacturer continuity with the original RG2012P-8252-C-T5. Both parts are active production components with AEC-Q200 automotive qualification. The RG2012N-8252-B-T5 offers improved temperature coefficient (±10ppm/°C versus ±25ppm/°C) and tighter tolerance (±0.1% versus ±0.25%). The RG2012P-8252-W-T5 provides the tightest tolerance available (±0.05%) while maintaining the same temperature coefficient as the original part.

Secondary Recommendation - Panasonic ERA-6AEB8252V:

The ERA-6AEB8252V from Panasonic Electronic Components provides AEC-Q200 automotive qualification with ±0.1% tolerance and maintains full compatibility with the original operating temperature range. This part is suitable for automotive applications requiring equivalent qualification levels.

Alternative Substitutes - Non-Automotive Applications:

For non-automotive applications where AEC-Q200 qualification is not required, the YAGEO RT0805BRD0782K5L and RT0805CRD0782K5L offer active production status with compatible electrical specifications. The RT0805BRD0782K5L provides ±0.1% tolerance, while the RT0805CRD0782K5L matches the original ±0.25% tolerance.

Higher Power Rating Option:

The TE Connectivity 8-2176093-7 provides 0.25W (1/4W) power rating, suitable for applications requiring increased power dissipation capability. This part maintains ±0.1% tolerance and -55°C to 155°C operating range but lacks AEC-Q200 qualification.

Temperature Range Consideration:

The Vishay MCU08050D8252BP500 operates to 125°C maximum, which is 30°C below the original specification. This part is suitable only for applications with maximum operating temperature not exceeding 125°C.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with tighter tolerance than the original RG2012P-8252-C-T5?

A: Yes. Substitute parts with tighter tolerance (±0.1% or ±0.05%) are direct upgrades and provide improved circuit accuracy. The RG2012N-8252-B-T5 (±0.1%), RG2012N-8252-W-T1 (±0.05%), RG2012P-8252-W-T5 (±0.05%), ERA-6AEB8252V (±0.1%), and RT0805BRD0782K5L (±0.1%) all meet or exceed the original tolerance specification.

Q: Is the 0805 package dimension identical across all substitute parts?

A: All substitute parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Height variations exist: the original part specifies 0.020" (0.50mm) maximum, while substitutes range from 0.020" to 0.026" (0.50mm to 0.65mm). These height variations are within standard PCB assembly tolerances and do not affect electrical performance or mechanical fit in standard 0805 footprints.

Q: Which substitute parts maintain AEC-Q200 automotive qualification?

A: The following substitute parts carry AEC-Q200 automotive qualification: RG2012N-8252-B-T5, RG2012N-8252-W-T1, RG2012P-8252-B-T5, RG2012P-8252-W-T5, and ERA-6AEB8252V. These parts are suitable for automotive applications requiring equivalent qualification levels to the original component.

Q: Can I use the TE Connectivity 8-2176093-7 as a direct substitute?

A: The 8-2176093-7 is functionally compatible but provides 0.25W (1/4W) power rating versus the original 0.125W (1/8W). This higher power rating is acceptable for direct substitution in circuits designed for 0.125W components. However, this part lacks AEC-Q200 qualification and is not suitable for automotive applications requiring the original qualification level.

Q: What is the difference between temperature coefficient values in substitute parts?

A: Temperature coefficient indicates resistance change per degree Celsius. The original part specifies ±25ppm/°C. Substitute parts with lower temperature coefficients (±10ppm/°C or ±15ppm/°C) provide improved stability across temperature variations. The RG2012N-8252-B-T5 and RG2012N-8252-W-T1 offer ±10ppm/°C, while the RP73D2A82K5BTDF offers ±15ppm/°C. Lower values are beneficial for precision analog circuits and temperature-sensitive applications.

Q: Is the Vishay MCU08050D8252BP500 suitable for all applications?

A: The MCU08050D8252BP500 operates to 125°C maximum, which is 30°C below the original specification of 155°C. This part is suitable only for applications with maximum operating temperature not exceeding 125°C. For applications requiring the full -55°C to 155°C range, use alternative substitutes that maintain this specification.

Q: Can I mix different substitute parts in the same circuit board?

A: Yes. All substitute parts maintain the same 82.5 kOhms resistance value, 0805 package, and 0.125W minimum power rating. Mixing parts with different tolerances is acceptable from a functional standpoint, though circuit design may benefit from using consistent tolerance grades to simplify production testing and quality control procedures.

Q: What is the difference between Susumu RG2012P and RG2012N series?

A: Both series are thin film 0805 chip resistors with identical package and electrical specifications. The primary difference is in temperature coefficient: RG2012P series specifies ±25ppm/°C, while RG2012N series specifies ±10ppm/°C. The RG2012N series provides superior temperature stability. Both series are available with multiple tolerance grades (±0.25%, ±0.1%, ±0.05%) and carry AEC-Q200 automotive qualification.
