AP431IBZTR-G1 Equivalent & Substitute Parts

Part Overview

The AP431IBZTR-G1 is a shunt voltage reference IC manufactured by Diodes Incorporated, classified as a Power Management (PMIC) component. This adjustable shunt voltage reference operates across a 2.5V to 36V output range with ±1% tolerance and supports 100 mA output current in a TO-92 through-hole package. The part is currently listed as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity. Active equivalent models maintain identical electrical specifications while offering improved availability and current product status.

Substitute Part Grouping Explanation

Substitution of the AP431IBZTR-G1 is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt (fixed requirement)
• Output Type: Adjustable (fixed requirement)
• Voltage Range: 2.5V minimum to 36V maximum (fixed requirement)
• Current - Output: 100 mA (fixed requirement)
• Tolerance: ±1% (fixed requirement)
• Current - Cathode: 100 µA (fixed requirement)
• Operating Temperature Range: -40°C ~ 125°C (fixed requirement)
• Package / Case: TO-92-3 (TO-226AA) Formed Leads (fixed requirement)
• Mounting Type: Through Hole (fixed requirement)
• RoHS Status: ROHS3 Compliant (fixed requirement)

The AP431SBZTR-G1 meets all substitution criteria as a direct equivalent from the same manufacturer, differing only in product status (active vs. obsolete) and packaging configuration (bulk vs. tape/reel).

Parameter Comparison

Engineering Selection Recommendations

The AP431SBZTR-G1 is a direct functional equivalent to the AP431IBZTR-G1. Both parts share identical electrical specifications, thermal operating range, and package configuration. The primary distinction is product lifecycle status: the AP431IBZTR-G1 is obsolete, while the AP431SBZTR-G1 maintains active status with current manufacturing support.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production continuity. The AP431SBZTR-G1 is available in bulk packaging, whereas the main part was supplied in tape/reel format. This packaging difference does not affect electrical performance or circuit compatibility.

For applications requiring the AP431IBZTR-G1, the AP431SBZTR-G1 provides equivalent performance with assured long-term availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the AP431SBZTR-G1 replace the AP431IBZTR-G1 in existing designs?

A: Yes. The AP431SBZTR-G1 is electrically and mechanically identical to the AP431IBZTR-G1. All electrical parameters, operating temperature range, output voltage specifications, current ratings, and package dimensions are equivalent. Direct substitution is possible without circuit modification.

Q: What is the difference between these two part numbers?

A: The parts differ in product status and packaging configuration only. The AP431IBZTR-G1 is obsolete and was supplied in tape/reel packaging. The AP431SBZTR-G1 is an active product available in bulk packaging. Electrical and functional specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance and REACH unaffected status. Regulatory certifications and environmental compliance are equivalent.

Q: Does packaging configuration affect circuit performance?

A: No. Packaging configuration (tape/reel vs. bulk) affects only procurement and handling methods. The component itself, its electrical characteristics, and circuit performance remain unchanged.

Q: What is the TO-92 package specification?

A: The TO-92 is a through-hole package with three formed leads, designated as TO-226-3 or TO-226AA. This package is compatible with standard PCB through-hole mounting and breadboard applications.
