Parameter Comparison

Engineering Selection Recommendations

Direct Functional Equivalent (Identical Specifications):

RG2012P-4640-W-T5 provides direct functional equivalence to the RG2012P-4640-W-T1, maintaining identical electrical specifications (464 Ohms ±0.05%, ±25ppm/°C temperature coefficient). The primary difference is packaging format (Tape & Reel versus bulk) and active product status. This part is suitable for applications where the original specifications are required without modification.

Enhanced Performance Alternatives:

RG2012N-4640-W-T1 offers improved temperature coefficient performance (±10ppm/°C versus ±25ppm/°C) while maintaining all other electrical and mechanical specifications. This upgrade is applicable to designs requiring enhanced thermal stability.

RG2012V-4640-W-T1 and RG2012V-4640-W-T5 provide superior temperature coefficient performance (±5ppm/°C) with identical tolerance and resistance specifications. These parts are suitable for applications demanding enhanced precision across the operating temperature range.

RG2012V-4640-P-T1 offers the highest precision specification with ±0.02% tolerance and ±5ppm/°C temperature coefficient. This part is applicable to designs requiring tighter tolerance control than the original specification.

All substitute parts maintain AEC-Q200 automotive qualification, anti-sulfur construction, ROHS3 compliance, and identical mechanical dimensions. Selection between alternatives depends on specific application requirements for temperature stability and tolerance precision.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-4640-W-T5 be used as a direct replacement for RG2012P-4640-W-T1?

A: Yes. RG2012P-4640-W-T5 is electrically and mechanically identical to RG2012P-4640-W-T1, with the same 464 Ohms resistance, ±0.05% tolerance, ±25ppm/°C temperature coefficient, and 0805 package. The difference is packaging format (Tape & Reel versus bulk) and active product status. Both parts are suitable for identical applications.

Q: What is the difference between the RG2012N and RG2012V series?

A: The RG2012N series offers ±10ppm/°C temperature coefficient, while the RG2012V series offers ±5ppm/°C temperature coefficient. Both maintain the same 464 Ohms resistance and ±0.05% tolerance. The RG2012V series provides enhanced thermal stability for applications requiring tighter temperature performance.

Q: Can I use RG2012V-4640-P-T1 in place of RG2012P-4640-W-T1?

A: Yes. RG2012V-4640-P-T1 is mechanically and thermally compatible with RG2012P-4640-W-T1. It provides superior specifications with ±0.02% tolerance (versus ±0.05%) and ±5ppm/°C temperature coefficient (versus ±25ppm/°C). This part is suitable for applications where the original specifications are acceptable or where enhanced precision is beneficial.

Q: Does packaging format (Tape & Reel versus bulk) affect electrical performance?

A: No. Packaging format does not affect electrical or mechanical performance. Tape & Reel packaging is standard for automated assembly processes and is functionally equivalent to bulk packaging. Selection between formats depends on manufacturing process requirements and inventory management practices.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All identified substitute parts maintain AEC-Q200 automotive qualification, anti-sulfur construction, and identical operating temperature range (-55°C to 155°C). All parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Which substitute part should I select for a new design?

A: For new designs, select from the active product status parts: RG2012P-4640-W-T5, RG2012N-4640-W-T1, RG2012V-4640-P-T1, RG2012V-4640-W-T1, or RG2012V-4640-W-T5. Selection depends on required temperature coefficient performance. If the original ±25ppm/°C specification is sufficient, RG2012P-4640-W-T5 is the direct equivalent. For enhanced thermal stability, select RG2012V series parts with ±5ppm/°C temperature coefficient.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design specifications allow for equal or tighter tolerance and temperature coefficient performance. All substitute parts maintain identical resistance value, power rating, package dimensions, and operating temperature range. Designs specified for ±0.05% tolerance and ±25ppm/°C temperature coefficient accept all listed substitutes. Designs with tighter specifications accept only parts meeting those requirements.
