APV3111GV Equivalent & Substitute Parts

Part Overview

The APV3111GV is a photovoltaic output optoisolator manufactured by Panasonic Electric Works, designed for high-voltage isolation applications requiring 1500Vrms isolation rating. This component features a single channel configuration in a 4-SSOP surface mount package and is classified as obsolete. The APV3111GV operates with DC input and photovoltaic output, making it suitable for applications requiring galvanic isolation without direct electrical connection between input and output circuits.

Due to its obsolete product status, sourcing original APV3111GV units presents supply chain challenges. Active substitute parts with equivalent electrical and mechanical specifications are available to ensure design continuity and system reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the APV3111GV are qualified based on strict equivalence of the following critical parameters:

Isolation Voltage: 1500Vrms (mandatory match)

Channel Configuration: 1 channel (mandatory match)

Input/Output Type: DC input with photovoltaic output (mandatory match)

Package Type: 4-SSOP surface mount configuration (mandatory match)

Electrical Characteristics: Forward voltage (Vf) of 1.47V typical and maximum forward current (If) of 30 mA (mandatory match)

Switching Performance: Turn on/off times of 400µs and 40µs respectively (mandatory match)

Operating Temperature Range: -40°C to 85°C (mandatory match)

The substitute parts APV3111GV1Y and APV3111GVY meet all these criteria and are manufactured by the same supplier, Panasonic Electric Works, ensuring design and functional compatibility with the original APV3111GV specification.

Parameter Comparison

Engineering Selection Recommendations

APV3111GV1Y is the manufacturer-recommended primary substitute for the obsolete APV3111GV. This part maintains active product status with Panasonic Electric Works and carries full compliance certifications including RoHS3 compliance and EAR99 ECCN classification. Current inventory of 1574 pieces supports immediate procurement requirements.

APV3111GVY serves as an alternative substitute with identical electrical and functional specifications to APV3111GV1Y. This variant offers the highest available inventory level at 8921 pieces, providing superior supply chain availability. REACH status is listed as vendor undefined; however, EAR99 ECCN classification applies.

Both substitute parts are supplied in Tape & Reel (TR) packaging format, which differs from the main part's unspecified packaging. This packaging format is standard for surface mount components and presents no functional or electrical impact on circuit performance.

Selection between APV3111GV1Y and APV3111GVY should be based on procurement lead time requirements and inventory availability. Both parts deliver equivalent performance and are direct functional replacements for the obsolete APV3111GV.

Frequently Asked Questions (FAQ)

Q: Can APV3111GV1Y and APV3111GVY be used interchangeably with APV3111GV?

A: Yes. Both substitute parts maintain identical electrical specifications including 1500Vrms isolation voltage, single-channel photovoltaic output configuration, DC input type, 1.47V forward voltage, 30 mA maximum forward current, and 400µs/40µs switching times. The 4-SSOP package footprint is identical, enabling direct PCB layout compatibility.

Q: What is the primary reason for substitution?

A: The APV3111GV is classified as obsolete, creating supply chain discontinuity. The active substitute parts APV3111GV1Y and APV3111GVY ensure continued component availability while maintaining full electrical and mechanical equivalence.

Q: Does the Tape & Reel packaging of substitute parts affect circuit performance?

A: No. Tape & Reel packaging is a supply format only and does not alter component electrical characteristics, performance, or reliability. The actual component and its 4-SSOP package remain identical.

Q: Are there compliance differences between the main part and substitutes?

A: The substitute parts carry active compliance certifications. APV3111GV1Y is RoHS3 compliant. Both substitutes carry EAR99 ECCN classification and HTSUS code 8541.49.8000. The obsolete main part does not carry current compliance documentation.

Q: Which substitute should be selected for new designs?

A: APV3111GV1Y is the manufacturer-recommended substitute and carries explicit RoHS3 compliance certification, making it the preferred choice for new designs requiring regulatory compliance documentation.

Q: Are there any thermal or environmental performance differences?

A: No. All three parts operate across the identical temperature range of -40°C to 85°C with equivalent thermal characteristics.
