Key Parameters

Substitute Part Grouping Explanation

Substitute parts are categorized based on electrical and mechanical compatibility with RG2012P-4023-W-T1. The critical matching parameters for substitution include: Resistance (402 kOhms), Tolerance (±0.05%), Power Rating (0.125W, 1/8W), Package Size (0805), Composition (Thin Film), Operating Temperature Range (-55°C ~ 155°C), and Automotive Qualification (AEC-Q200).

Direct Substitute: RG2012P-4023-W-T5 matches all electrical and mechanical parameters with the original part. The only difference is packaging format (Tape & Reel vs. the original packaging).

Upgrade Substitute: RG2012N-4023-W-T1 maintains identical electrical and mechanical specifications but offers an improved Temperature Coefficient of ±10ppm/°C compared to the original ±25ppm/°C, providing enhanced stability across temperature variations.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are Active status products and maintain full compliance with ROHS3 and AEC-Q200 automotive standards, ensuring regulatory and reliability requirements are met.

RG2012P-4023-W-T5 provides a direct replacement with identical electrical specifications. This part is suitable for applications where the original ±25ppm/°C temperature coefficient is adequate.

RG2012N-4023-W-T1 offers improved temperature stability with ±10ppm/°C temperature coefficient while maintaining all other specifications. This part is suitable for applications requiring enhanced performance across the operating temperature range.

Frequently Asked Questions (FAQ)

Q: What are the key criteria for substituting RG2012P-4023-W-T1?

A: The substitute part must match: 402 kOhms resistance, ±0.05% tolerance, 0.125W power rating, 0805 package size, thin film composition, -55°C ~ 155°C operating temperature, and AEC-Q200 automotive qualification.

Q: Can RG2012N-4023-W-T1 replace RG2012P-4023-W-T1 in automotive applications?

A: RG2012N-4023-W-T1 is qualified to AEC-Q200 and meets all electrical and mechanical specifications of the original part.

Q: What is the difference between RG2012P-4023-W-T5 and RG2012P-4023-W-T1?

A: RG2012P-4023-W-T5 has identical electrical and mechanical specifications. The primary difference is Active product status and Tape & Reel packaging format.
