• Height seated maximum (within 0.020" to 0.022")

All identified substitute parts maintain identical electrical specifications and package dimensions while meeting or exceeding the original part's performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Identical Specifications): RG2012P-2742-W-T5 is a direct functional equivalent to the RG2012P-2742-W-T1. Both parts are manufactured by Susumu with identical electrical and mechanical specifications. The primary distinction is product status: RG2012P-2742-W-T5 is active and currently in production, whereas RG2012P-2742-W-T1 is obsolete. The packaging difference (Tape & Reel versus unspecified) does not affect electrical performance or PCB assembly compatibility.

Enhanced Performance Alternative: RG2012N-2742-W-T1 is manufactured by Susumu and provides improved temperature stability with a temperature coefficient of ±10ppm/°C compared to the original ±25ppm/°C. All other electrical and mechanical parameters remain identical. This part is active and suitable for applications requiring tighter temperature coefficient performance.

Cross-Manufacturer Substitute: TNPU080527K4AZEN00 is manufactured by Vishay Dale and meets all critical electrical specifications. This part features an enhanced temperature coefficient of ±5ppm/°C and includes moisture-resistant construction. The maximum operating temperature is 125°C (versus 155°C for Susumu parts), which is acceptable for most automotive applications. The seated height maximum is 0.022" compared to 0.020", which remains within standard PCB assembly tolerances. This part is active and widely available.

Selection Criteria:

• For direct replacement with active inventory: RG2012P-2742-W-T5
• For improved temperature stability: RG2012N-2742-W-T1
• For cross-manufacturer sourcing: TNPU080527K4AZEN00

All substitute parts maintain AEC-Q200 automotive qualification and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-2742-W-T5 be used as a direct replacement for RG2012P-2742-W-T1?

A: Yes. RG2012P-2742-W-T5 is electrically and mechanically identical to RG2012P-2742-W-T1. Both parts have 27.4 kOhms resistance, ±0.05% tolerance, 0.125W power rating, 0805 package format, and ±25ppm/°C temperature coefficient. The primary difference is that RG2012P-2742-W-T5 is currently in active production status.

Q: What is the difference between RG2012N-2742-W-T1 and RG2012P-2742-W-T1?

A: The primary difference is temperature coefficient: RG2012N-2742-W-T1 has ±10ppm/°C while RG2012P-2742-W-T1 has ±25ppm/°C. All other specifications including resistance, tolerance, power rating, package, and operating temperature range are identical. RG2012N-2742-W-T1 is active and provides superior temperature stability.

Q: Can TNPU080527K4AZEN00 replace the original part in all applications?

A: TNPU080527K4AZEN00 is compatible with the original part for most applications. Key considerations: the maximum operating temperature is 125°C (versus 155°C), and the seated height is 0.022" (versus 0.020"). These differences are within standard PCB assembly tolerances. The part maintains AEC-Q200 qualification and ROHS3 compliance.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. RG2012P-2742-W-T5, RG2012N-2742-W-T1, and TNPU080527K4AZEN00 all carry AEC-Q200 automotive qualification, meeting the same reliability standards as the original part.

Q: What is the significance of the packaging difference (Tape & Reel)?

A: Tape & Reel packaging is standard for automated PCB assembly processes and does not affect electrical performance or component functionality. The component itself remains identical; only the delivery format differs.

Q: Which substitute part offers the best temperature stability?

A: TNPU080527K4AZEN00 offers the best temperature stability with ±5ppm/°C temperature coefficient. RG2012N-2742-W-T1 provides intermediate stability at ±10ppm/°C. Both are superior to the original RG2012P-2742-W-T1 at ±25ppm/°C.
