Package type: 0805 (2012 Metric) (exact match required)
Composition: Thin Film (exact match required)
Tolerance: ±0.1% or tighter (equal or superior tolerance acceptable)
Power rating: 0.125W minimum (equal or higher acceptable)
Temperature coefficient: ±25ppm/°C or tighter (equal or superior acceptable)
Operating temperature range: -55°C to 155°C minimum (equal or wider range acceptable)

Compliance Parameters:

Engineering Selection Recommendations

Direct Equivalent (Same Packaging, Identical Specifications):

RG2012P-6492-B-T5 (Susumu) is the direct equivalent to RG2012P-6492-B-T1, differing only in packaging format (Tape & Reel versus bulk). This part maintains identical electrical specifications, AEC-Q200 automotive qualification, and anti-sulfur coating. Product status is active with 5575 units in stock.

Automotive-Qualified Alternatives:

ERA-6AEB6492V (Panasonic) provides full electrical and thermal compatibility with AEC-Q200 qualification. Operating temperature range matches the original specification (-55°C to 155°C). This part is active with 8095 units in stock.

TNPW080564K9BEEA (Vishay Dale) offers superior power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C to 175°C) while maintaining AEC-Q200 qualification and anti-sulfur coating. This part is active with 30695 units in stock.

Upgraded Specifications (Susumu Series):

RG2012N-6492-B-T5 provides improved temperature coefficient (±10ppm/°C versus ±25ppm/°C) while maintaining all other specifications and AEC-Q200 qualification. Active status with 895 units in stock.

RG2012N-6492-W-T1 and RG2012P-6492-W-T5 offer tighter tolerance (±0.05% versus ±0.1%) with active status and AEC-Q200 qualification.

Non-Automotive Alternatives:

RT0805BRD0764K9L (YAGEO), MCU08050D6492BP100, and MCU08050D6492BP500 (Vishay Beyschlag) provide electrical compatibility but lack AEC-Q200 automotive qualification. MCU series parts have reduced operating temperature range (-55°C to 125°C). These parts are suitable for non-automotive applications requiring equivalent electrical performance.

7-2176093-7 (TE Connectivity) offers higher power rating (0.25W) but lacks AEC-Q200 qualification and is not recommended for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-6492-B-T5 be used as a direct replacement for RG2012P-6492-B-T1?

A: Yes. RG2012P-6492-B-T5 is electrically and mechanically identical to RG2012P-6492-B-T1. The difference is packaging format: RG2012P-6492-B-T1 is supplied in bulk, while RG2012P-6492-B-T5 is supplied in Tape & Reel format. Both maintain identical specifications, AEC-Q200 qualification, and anti-sulfur coating.

Q: What is the difference between Susumu RG series parts with "P" and "N" designations?

A: The "N" designation indicates improved temperature coefficient (±10ppm/°C) compared to "P" designation (±25ppm/°C). Both maintain identical resistance, tolerance, power rating, and package specifications. The "N" series represents an upgrade in thermal stability.

Q: Can TNPW080564K9BEEA replace RG2012P-6492-B-T1 in automotive applications?

A: Yes. TNPW080564K9BEEA maintains AEC-Q200 automotive qualification, identical resistance and tolerance, and compatible operating temperature range (-55°C to 175°C exceeds the original -55°C to 155°C). The higher power rating (0.26W versus 0.125W) provides additional thermal margin without affecting circuit performance.

Q: Are there restrictions on using non-AEC-Q200 qualified parts?

A: Non-AEC-Q200 parts (RT0805BRD0764K9L, MCU series, 7-2176093-7) are suitable for non-automotive applications. For automotive or high-reliability applications requiring AEC-Q200 qualification, use only qualified alternatives: RG2012P-6492-B-T5, RG2012N-6492-B-T5, RG2012N-6492-W-T1, RG2012P-6492-W-T5, ERA-6AEB6492V, or TNPW080564K9BEEA.

Q: What is the impact of operating temperature range differences?

A: MCU series parts (MCU08050D6492BP100, MCU08050D6492BP500) have reduced upper temperature limit (125°C versus 155°C). These parts are not suitable for applications requiring full -55°C to 155°C range. TNPW080564K9BEEA extends the upper limit to 175°C, providing additional margin for high-temperature environments.

Q: Does tolerance selection affect circuit performance?

A: Tighter tolerance (±0.05% in RG2012N-6492-W-T1 and RG2012P-6492-W-T5) provides improved accuracy compared to ±0.1% specification. Selection depends on circuit requirements. If the original design specifies ±0.1%, tighter tolerance parts are compatible upgrades. If circuit design requires ±0.1% or looser, both tolerance levels are acceptable.

Q: What is the significance of anti-sulfur coating?

A: Anti-sulfur coating protects the resistor from corrosion in sulfur-containing environments. RG2012P-6492-B-T1, RG2012N-6492-B-T5, RG2012N-6492-W-T1, RG2012P-6492-W-T5, TNPW080564K9BEEA, and MCU08050D6492BP100/BP500 include this feature. RT0805BRD0764K9L and 7-2176093-7 do not specify anti-sulfur coating.

Q: Can parts with different power ratings be interchanged?

A: Yes, provided the higher power rating does not create thermal or size constraints. 7-2176093-7 (0.25W) and TNPW080564K9BEEA (0.26W) have higher power ratings than the original 0.125W specification. These parts are physically compatible in 0805 package and provide additional thermal margin. Lower power-rated parts cannot replace the original specification.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All listed substitute parts maintain MSL 1 classification, ensuring compatibility with standard storage and handling procedures.
