HMHA2801AV Equivalent & Substitute Parts

Part Overview

The HMHA2801AV is an optoisolator with transistor output manufactured by onsemi, designed for high-voltage isolation applications. This component provides 3750Vrms isolation with a single channel configuration in a 4-Mini-Flat surface mount package. The part is currently in active production status with substantial inventory availability (21300 pcs). Substitute parts may be required due to supply chain constraints, regional availability, or procurement preferences while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HMHA2801AV is determined by strict equivalence across the following critical parameters:

• Voltage isolation rating: 3750Vrms
• Number of channels: 1
• Output type: Transistor
• Current transfer ratio range: 80% to 160% @ 5mA
• Maximum output voltage: 80V
• Maximum output current per channel: 50mA
• Maximum Vce saturation: 300mV
• Rise and fall time: 3µs each
• Package type: 4-Mini-Flat (4-SOIC)
• Operating temperature range: -55°C to 100°C
• Compliance: ROHS3, MSL 1

The HMHA2801A meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical performance specifications, mechanical dimensions, and environmental ratings, making them directly interchangeable in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HMHA2801AV and HMHA2801A are active production parts from onsemi with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Regional supplier preferences and procurement channels
• Cost considerations where applicable
• Compliance requirements: both parts meet ROHS3 and are REACH unaffected

The HMHA2801AV currently maintains higher inventory levels (21300 pcs) compared to HMHA2801A (4212 pcs), which may influence procurement decisions for high-volume applications. Both parts carry MSL 1 rating, indicating no moisture sensitivity restrictions during storage and handling.

Frequently Asked Questions (FAQ)

Q: Are HMHA2801AV and HMHA2801A pin-compatible? A: Yes. Both parts use the 4-Mini-Flat package with identical pinout and electrical characteristics, enabling direct substitution without circuit modification.

Q: What determines if a part can substitute for the HMHA2801AV? A: A substitute must match all critical parameters: 3750Vrms isolation voltage, single channel configuration, transistor output type, 80-160% current transfer ratio at 5mA, 80V maximum output voltage, 50mA maximum output current, 300mV maximum Vce saturation, 3µs rise and fall times, and -55°C to 100°C operating temperature range.

Q: Do both parts meet the same compliance standards? A: Yes. Both HMHA2801AV and HMHA2801A are ROHS3 compliant, REACH unaffected, and carry MSL 1 moisture sensitivity rating.

Q: Can these parts be used interchangeably in existing designs? A: Yes. The parts are parametric equivalents with identical electrical performance and mechanical dimensions, allowing direct substitution in PCB layouts and circuit designs without redesign.

Q: What is the significance of the MSL 1 rating? A: MSL 1 indicates unlimited moisture sensitivity level, meaning these components have no moisture-related storage or handling restrictions and do not require special desiccant packaging or baking procedures.
