Substitute Part Grouping Explanation

Substitute parts for the S-873382EUP-APHT2G are selected based on strict electrical and mechanical parameter matching within the ABLIC S-87x series. All substitute parts maintain identical specifications across the following critical parameters:

Output voltage: 3.3V fixed
Output current: 30mA
Input voltage maximum: 24V
Voltage dropout: 0.7V @ 30mA
Quiescent current: 8 µA
Package type: SOT-89-5/6 surface mount
Operating temperature range: -40°C ~ 85°C

Frequently Asked Questions (FAQ)

Q: Can S-873382EUP-APHT2G be directly replaced with any of the listed substitute parts?

A: Yes. All substitute parts are parametrically equivalent with identical electrical specifications (3.3V output, 30mA current, 0.7V dropout, 8 µA quiescent current) and identical package type (SOT-89-5/6). Direct pin-for-pin replacement is supported without circuit modification.

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

A: Tape & Reel (TR) packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape (CT) packaging is supplied as individual pieces cut from the carrier tape, typically for lower-volume or manual assembly applications. Electrical performance is identical; the difference is in supply format and handling.

Q: Why is S-873382EUP-APHT2G marked as Not For New Designs?

A: This designation indicates the part has reached end-of-life status. ABLIC Inc. recommends transitioning to Active alternatives within the S-87x series for new product designs and long-term production continuity.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant status with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original S-873382EUP-APHT2G.

Q: Which substitute part has the highest inventory availability?

A: S-873344AUP-OAHT2U (Cut Tape format) has the highest inventory at 1827 pieces. For Tape & Reel format, S-873341AUP-OAET2U has 1034 pieces available.

Q: Can I use these parts interchangeably in existing designs?

A: Yes. All substitute parts maintain identical electrical and thermal characteristics, operating temperature range (-40°C ~ 85°C), and protection features (Short Circuit protection with Voltage Detection control). No design changes are required for substitution.
