REF1925AIDDCR Equivalent & Substitute Parts

Part Overview

The REF1925AIDDCR is a series voltage reference IC manufactured by Texas Instruments, classified as a Power Management (PMIC) component. This fixed 2.5V reference device operates with ±0.1% tolerance and delivers up to 20 mA output current in a compact SOT-23-5 thin package. The part is actively produced and widely used in precision analog circuits requiring stable voltage references. Substitute parts are identified when packaging or supply chain considerations necessitate alternative sourcing while maintaining identical electrical performance and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the REF1925AIDDCR are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

  • Fixed output voltage of 2.5V
  • Output current rating of 20 mA
  • Tolerance specification of ±0.1%
  • Temperature coefficient of 25 ppm/°C
  • Input voltage range of 2.52V ~ 5.5V
  • Supply current of 460 µA
  • Operating temperature range of -40°C ~ 125°C
  • SOT-23-5 thin package (TSOT-23-5)
  • Surface mount mounting type
  • Active product status
  • ROHS3 compliance and REACH unaffected status

Substitute parts differ only in packaging format (tape and reel configuration) while maintaining identical electrical specifications and mechanical compatibility.

Engineering Selection Recommendations

Both the REF1925AIDDCR and REF1925AIDDCT are active products from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts is determined by supply chain availability and packaging requirements rather than technical performance differences.

The REF1925AIDDCR is supplied in Digi-Reel® format, while the REF1925AIDDCT is available in both Cut Tape (CT) and Digi-Reel® configurations. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can REF1925AIDDCT replace REF1925AIDDCR in production?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format. REF1925AIDDCT offers additional Cut Tape (CT) packaging option alongside Digi-Reel®, providing flexibility in supply chain sourcing.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical electrical performance: 2.5V fixed output, ±0.1% tolerance, 20 mA output current, 25 ppm/°C temperature coefficient, and identical input/output specifications across the full operating temperature range of -40°C to 125°C.

Q: Do both parts use the same package?

A: Yes. Both parts use the SOT-23-5 thin package (TSOT-23-5) with identical pin configuration and mechanical dimensions, ensuring direct compatibility on PCBs designed for either part number.

Q: What is the difference between Digi-Reel® and Cut Tape (CT) packaging?

A: Digi-Reel® is a continuous reel format for automated pick-and-place assembly. Cut Tape (CT) is pre-cut tape supplied on a reel, suitable for manual or semi-automated assembly. Both formats contain the same component.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both REF1925AIDDCR and REF1925AIDDCT are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
