Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-8450-D-T5 is determined by the following critical parameters: resistance value (845 Ohms), package format (0805), composition (thin film), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1).

Substitute parts are grouped into two categories based on tolerance specification:

Tolerance Upgrade Substitutes (±0.1%): Parts with improved tolerance specification compared to the main part (±0.5%). These include RG2012P-8450-B-T5 (Susumu), ERA-6AEB8450V (Panasonic), and RT0805BRD07845RL (YAGEO). All maintain identical 0.125W power rating, 0805 package, thin film composition, and automotive AEC-Q200 qualification where applicable.

Power Rating Upgrade Substitute (0.25W): Part 1-2176092-1 (TE Connectivity) provides increased power dissipation capability (0.25W versus 0.125W) while maintaining 845 Ohm resistance, ±0.1% tolerance, 0805 package, and thin film composition. This part does not carry AEC-Q200 automotive rating.

All substitute parts maintain identical resistance value, package dimensions, temperature coefficient, operating temperature range, and RoHS3 compliance status.

Engineering Selection Recommendations

For Automotive Applications with AEC-Q200 Requirement:

Select RG2012P-8450-B-T5 (Susumu) or ERA-6AEB8450V (Panasonic) as direct substitutes. Both parts maintain AEC-Q200 automotive qualification, anti-sulfur construction (Susumu only), identical power rating (0.125W), and provide improved tolerance specification (±0.1% versus ±0.5%). RG2012P-8450-B-T5 offers the highest inventory availability (8352 pieces) and maintains anti-sulfur construction identical to the main part.

For Non-Automotive Applications or Tolerance-Flexible Designs:

RT0805BRD07845RL (YAGEO) provides equivalent electrical performance with ±0.1% tolerance and 0.125W power rating in 0805 package. This part does not carry AEC-Q200 certification and is suitable for general-purpose applications.

For Applications Requiring Increased Power Dissipation:

1-2176092-1 (TE Connectivity) is the only substitute offering 0.25W power rating while maintaining 845 Ohm resistance and ±0.1% tolerance in 0805 package. This part does not carry AEC-Q200 automotive qualification and lacks anti-sulfur construction. Use only when increased power dissipation is required and automotive certification is not mandated.

Inventory Considerations:

RG2012P-8450-B-T5 (8352 pieces), ERA-6AEB8450V (7787 pieces), and 1-2176092-1 (1695 pieces) offer superior stock availability compared to the main part (937 pieces) and RT0805BRD07845RL (722 pieces).

Frequently Asked Questions (FAQ)

Q: Can RG2012P-8450-B-T5 be used as a direct replacement for RG2012P-8450-D-T5?

A: Yes. Both parts share identical resistance (845 Ohms), power rating (0.125W), package (0805), composition (thin film), temperature coefficient (±25ppm/°C), operating temperature range (-55°C ~ 155°C), AEC-Q200 automotive qualification, anti-sulfur construction, and RoHS3 compliance. RG2012P-8450-B-T5 provides improved tolerance specification (±0.1% versus ±0.5%).

Q: What is the difference between the main part and ERA-6AEB8450V?

A: Both parts are functionally equivalent with 845 Ohms resistance, 0.125W power rating, 0805 package, ±25ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. ERA-6AEB8450V (Panasonic) provides ±0.1% tolerance compared to ±0.5% for the main part and carries AEC-Q200 automotive qualification. The main part includes anti-sulfur construction, which is not specified for ERA-6AEB8450V.

Q: Why does 1-2176092-1 have a different power rating?

A: 1-2176092-1 is rated for 0.25W (1/4W) power dissipation compared to 0.125W (1/8W) for the main part. This higher power rating accommodates applications requiring greater thermal dissipation capability. All other electrical parameters (resistance, tolerance, temperature coefficient, operating temperature) remain equivalent. The increased power rating results in a slightly higher seated height (0.026" versus 0.020").

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (RG2012P-8450-B-T5, 1-2176092-1, ERA-6AEB8450V, RT0805BRD07845RL) are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the main part specifications.

Q: Which substitute part is recommended for automotive applications?

A: RG2012P-8450-B-T5 (Susumu) and ERA-6AEB8450V (Panasonic) both carry AEC-Q200 automotive qualification. RG2012P-8450-B-T5 additionally includes anti-sulfur construction, matching the main part's automotive-grade specifications. RT0805BRD07845RL and 1-2176092-1 do not carry AEC-Q200 certification and are not suitable for automotive applications requiring this qualification.

Q: Can RT0805BRD07845RL be used in place of the main part?

A: RT0805BRD07845RL provides equivalent electrical performance with 845 Ohms resistance, ±0.1% tolerance, 0.125W power rating, and 0805 package. However, this part does not carry AEC-Q200 automotive qualification or anti-sulfur construction. Use only in non-automotive applications or where automotive certification is not required.

Q: What is the physical difference between substitute parts in the 0805 package?

A: All substitute parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Seated height varies slightly: RG2012P-8450-D-T5 and RG2012P-8450-B-T5 are 0.020" maximum, ERA-6AEB8450V and RT0805BRD07845RL are 0.024" maximum, and 1-2176092-1 is 0.026" maximum. These variations do not affect PCB layout compatibility for standard 0805 footprints.

Q: Are all parts available in Tape & Reel packaging?

A: Yes. All listed parts (main and substitutes) are supplied in Tape & Reel (TR) packaging format suitable for automated assembly processes.
