Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Manufacturer, Active Status): RG2012P-334-W-T5 is the primary direct substitute for RG2012P-334-W-T1. Both components are manufactured by Susumu with identical electrical specifications, temperature coefficient, and operating temperature range. The primary difference is packaging format (Tape & Reel versus bulk) and active product status. This part is recommended for applications requiring continuity with the original design specification.

Upgraded Alternative (Enhanced Temperature Coefficient): RG2012N-334-W-T5 offers improved temperature stability with ±10ppm/°C coefficient compared to the original ±25ppm/°C specification. Manufactured by Susumu and maintaining all other electrical and mechanical parameters, this component is suitable for applications where enhanced temperature performance is beneficial. Operating temperature range remains -55°C ~ 155°C.

Cross-Manufacturer Substitute (Enhanced Features): TNPU0805330KAZEN00 from Vishay Dale provides equivalent electrical performance with superior temperature coefficient (±5ppm/°C) and additional moisture-resistant coating. This component is qualified to AEC-Q200 and RoHS3 compliant. The maximum seated height is 0.022" (0.55mm) compared to 0.020" (0.50mm) for Susumu parts, and the upper operating temperature limit is 125°C rather than 155°C. This substitute is applicable where space constraints permit the additional 0.002" height and thermal requirements do not exceed 125°C.

All substitute parts maintain the mandatory electrical specifications (330 kOhms, ±0.05% tolerance, 0.125W power rating) and automotive AEC-Q200 qualification required for direct functional replacement.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-334-W-T5 be used as a direct replacement for RG2012P-334-W-T1?

A: Yes. RG2012P-334-W-T5 is electrically and mechanically identical to RG2012P-334-W-T1. Both components have 330 kOhms resistance, ±0.05% tolerance, 0.125W power rating, 0805 package, and ±25ppm/°C temperature coefficient. The primary difference is packaging format (Tape & Reel versus bulk) and active product status.

Q: What is the difference between RG2012P-334-W-T5 and RG2012N-334-W-T5?

A: The primary difference is temperature coefficient. RG2012P-334-W-T5 has ±25ppm/°C while RG2012N-334-W-T5 has ±10ppm/°C. All other electrical and mechanical specifications are identical. RG2012N-334-W-T5 provides improved temperature stability for applications requiring tighter performance across the operating temperature range.

Q: Is TNPU0805330KAZEN00 compatible with the original RG2012P-334-W-T1?

A: TNPU0805330KAZEN00 is electrically compatible with identical resistance, tolerance, power rating, and package specifications. However, the maximum seated height is 0.022" (0.55mm) compared to 0.020" (0.50mm) for the original part. Additionally, the upper operating temperature limit is 125°C rather than 155°C. Verify that these dimensional and thermal differences are acceptable for the specific application before substitution.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. RG2012P-334-W-T5, RG2012N-334-W-T5, and TNPU0805330KAZEN00 are all AEC-Q200 qualified, meeting automotive reliability standards equivalent to the original RG2012P-334-W-T1.

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

A: Bulk packaging (RG2012P-334-W-T1) is supplied in loose form, while Tape & Reel format (RG2012P-334-W-T5, RG2012N-334-W-T5, TNPU0805330KAZEN00) is supplied on continuous tape for automated assembly equipment. The electrical and mechanical specifications are identical; packaging format selection depends on assembly process requirements and inventory management practices.

Q: Which substitute offers the best temperature stability?

A: TNPU0805330KAZEN00 offers the best temperature stability with ±5ppm/°C temperature coefficient, compared to ±25ppm/°C for RG2012P-334-W-T5 and ±10ppm/°C for RG2012N-334-W-T5. However, this component has a maximum operating temperature of 125°C, which may be limiting for applications requiring the full -55°C ~ 155°C range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RG2012P-334-W-T5, RG2012N-334-W-T5, and TNPU0805330KAZEN00 are all RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the environmental compliance of the original RG2012P-334-W-T1.
