H11AA2G Equivalent & Substitute Parts

Part Overview

The H11AA2G is an optoisolator transistor manufactured by Isocom Components 2004 LTD, designed for AC and DC input applications requiring galvanic isolation. This single-channel device features a transistor output with base connection and operates across a wide temperature range of -30°C to 100°C. The part is currently active in production with 1176 units in stock. Substitute parts are identified when component availability is limited, supply chain disruptions occur, or inventory levels require alternative sourcing while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the H11AA2G is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part H11AA2XG maintains identical specifications in the following key areas:

• Single-channel optoisolator configuration
• 7.5Vpk isolation voltage
• 10% minimum current transfer ratio at 10mA input
• Transistor output with base connection
• 35V maximum output voltage
• 50mA maximum output current per channel
• 400mV maximum Vce saturation voltage
• -30°C to 100°C operating temperature range
• 6-DIP through-hole package (0.400", 10.16mm)
• ROHS3 compliance and MSL Level 1 rating

Both parts belong to the H11A series and share identical input type capability (AC, DC), forward voltage characteristics (1.2V typical), and rise/fall time specifications (4µs, 3µs).

Parameter Comparison

Engineering Selection Recommendations

Both H11AA2G and H11AA2XG are active production parts from Isocom Components 2004 LTD with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation. The H11AA2G currently maintains higher inventory (1176 units) compared to H11AA2XG (1087 units). Both parts carry identical regulatory classifications (ECCN EAR99, HTSUS 8541.49.8000) and moisture sensitivity ratings. For applications requiring galvanic isolation in AC or DC input circuits with transistor output control, either part provides equivalent performance within the specified electrical and thermal operating envelope.

Frequently Asked Questions (FAQ)
