Engineering Selection Recommendations

RG2012P-4423-W-T5 (Direct Substitute)

The RG2012P-4423-W-T5 is a direct functional equivalent to the RG2012P-4423-W-T1. Both parts share identical electrical specifications, including 442 kOhms resistance, ±0.05% tolerance, ±25ppm/°C temperature coefficient, and 0.125W power rating. The primary distinction is packaging format: RG2012P-4423-W-T5 is supplied in Tape & Reel (TR) configuration versus bulk packaging for the main part. This substitute maintains full compliance with ROHS3, AEC-Q200 automotive qualification, and REACH requirements. Active product status ensures continued availability and supply chain support.

RG2012N-4423-W-T1 (Upgrade Substitute)

The RG2012N-4423-W-T1 represents an upgraded alternative with enhanced performance characteristics. This part maintains all core electrical specifications (442 kOhms, ±0.05% tolerance, 0.125W power rating) and automotive AEC-Q200 qualification. The significant improvement is a tighter temperature coefficient of ±10ppm/°C compared to ±25ppm/°C in the main part, providing superior temperature stability for precision applications. The RG2012N-4423-W-T1 is supplied in Tape & Reel (TR) format and carries Active product status. Full ROHS3 and REACH compliance is maintained.

Both substitute parts are suitable for direct replacement in applications where the RG2012P-4423-W-T1 is specified, with the RG2012N-4423-W-T1 offering enhanced performance for temperature-sensitive circuit designs.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-4423-W-T5 be used as a direct replacement for RG2012P-4423-W-T1?

A: Yes. The RG2012P-4423-W-T5 is electrically and mechanically identical to the RG2012P-4423-W-T1. Both parts have 442 kOhms resistance, ±0.05% tolerance, ±25ppm/°C temperature coefficient, and 0.125W power rating in 0805 package. The only difference is packaging format (Tape & Reel versus bulk). Both are AEC-Q200 qualified and ROHS3 compliant.

Q: What is the advantage of RG2012N-4423-W-T1 over RG2012P-4423-W-T1?

A: The RG2012N-4423-W-T1 provides a tighter temperature coefficient of ±10ppm/°C compared to ±25ppm/°C in the RG2012P-4423-W-T1. This enhanced temperature stability is beneficial for precision analog circuits and applications requiring minimal drift across the -55°C to 155°C operating range. All other electrical and mechanical specifications remain identical.

Q: Are all substitute parts automotive qualified?

A: Yes. Both RG2012P-4423-W-T5 and RG2012N-4423-W-T1 carry AEC-Q200 automotive qualification, matching the main part specification. All three parts are suitable for automotive applications.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging (RG2012P-4423-W-T1) is supplied in loose form, while Tape & Reel (TR) packaging (RG2012P-4423-W-T5 and RG2012N-4423-W-T1) is supplied on continuous tape for automated assembly equipment. Tape & Reel format is standard for high-volume production environments. Electrical performance is identical between packaging formats.

Q: Are these parts RoHS compliant?

A: Yes. All three parts—RG2012P-4423-W-T1, RG2012P-4423-W-T5, and RG2012N-4423-W-T1—are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.

Q: Why is RG2012P-4423-W-T1 marked as Obsolete?

A: The RG2012P-4423-W-T1 carries Obsolete status, indicating it is no longer in active production. The substitute parts RG2012P-4423-W-T5 and RG2012N-4423-W-T1 maintain Active status and are recommended for new designs and ongoing production support.

Q: Can I mix RG2012P-4423-W-T5 and RG2012N-4423-W-T1 in the same circuit?

A: Both parts are electrically compatible and can be used interchangeably in the same circuit. However, the RG2012N-4423-W-T1 has a tighter temperature coefficient (±10ppm/°C). For circuits requiring matched temperature stability across multiple resistors, consistent use of one part number is recommended.

Q: What is the moisture sensitivity level, and why does it matter?

A: All three parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements. This simplifies storage and handling procedures compared to higher MSL ratings.
