Substitute Part Grouping Explanation

Substitute parts for the H11A2G are qualified based on the following critical parameters that determine functional and mechanical interchangeability:

• Number of Channels: 1 channel (single-channel isolation requirement)
• Voltage - Isolation: 7.5Vpk (isolation voltage specification)
• Current Transfer Ratio (Min): 20% @ 10mA (optical coupling efficiency)
• Output Type: Transistor with Base (output configuration)
• Voltage - Output (Max): 30V (maximum collector voltage rating)
• Current - Output / Channel: 50mA (maximum output current)
• Rise / Fall Time (Typ): 2µs, 2µs (switching speed)
• Vce Saturation (Max): 400mV (saturation voltage)
• Operating Temperature: -55°C ~ 100°C (thermal operating range)
• Package / Case: 6-DIP (0.400", 10.16mm) (physical form factor and pin compatibility)
• Mounting Type: Through Hole (PCB assembly method)
• RoHS Status: ROHS3 Compliant (environmental compliance)

All substitute parts listed match these parameters exactly, ensuring direct functional and mechanical replacement capability.

Frequently Asked Questions (FAQ)

Q: Can H11A2XG, H11A3XG, and TIL116XG be used interchangeably with H11A2G?

A: Yes. All three parts match the H11A2G across all critical electrical parameters including isolation voltage, current transfer ratio, output voltage and current ratings, switching speed, and saturation voltage. They share identical 6-DIP through-hole packaging and operating temperature range, enabling direct PCB-level substitution without circuit modification.

Q: What determines whether a part qualifies as a substitute for the H11A2G?

A: Substitution is based on matching the following parameters: single-channel configuration, 7.5Vpk isolation voltage, 20% minimum current transfer ratio at 10mA, transistor output with base access, 30V maximum output voltage, 50mA maximum output current, 2µs rise and fall times, 400mV maximum saturation voltage, -55°C to 100°C operating temperature, and 6-DIP through-hole package format.

Q: Are there any differences in packaging or mounting between these parts?

A: No. All parts use identical 6-DIP (0.400", 10.16mm) through-hole packaging and mounting type, ensuring mechanical compatibility with existing PCB designs and assembly processes.

Q: Do all substitute parts meet the same compliance standards as the H11A2G?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the H11A2G compliance profile.

Q: Which substitute part should be selected based on availability?

A: TIL116XG offers the highest current inventory (1126 units). However, all three substitutes maintain active production status and adequate stock levels for supply chain planning.
