Substitute Part Grouping Explanation

Substitute parts for the H11A2 are qualified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitutability:

• Single-channel configuration with identical isolation voltage (7.5Vpk)
• Minimum current transfer ratio of 20% @ 10mA
• Transistor output with base connection
• Maximum output voltage of 30V
• Output current capability of 50mA per channel
• Vce saturation maximum of 400mV
• Operating temperature range of -55°C to 100°C
• 6-DIP through-hole package (0.300", 7.62mm)
• Input type: DC
• Compliance with ROHS3 and REACH requirements

Only parts meeting all these parameters are listed as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the H11A2 and TIL116X are active products from the same manufacturer with identical electrical specifications and mechanical packaging. Selection between these parts should be based on:

• Inventory availability: H11A2 has 1483 units in stock; TIL116X has 759 units in stock
• Supply chain lead times and procurement timelines
• Design documentation and historical usage patterns
• Compliance requirements: Both parts meet ROHS3 and REACH standards

No performance degradation occurs when substituting between these parts, as all critical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can TIL116X replace H11A2 in existing designs? A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including isolation voltage, current transfer ratio, output characteristics, and package dimensions.

Q: Are there any pin compatibility concerns? A: No. Both parts use the 6-DIP (0.300", 7.62mm) through-hole package with identical pinout and mounting requirements.

Q: Do both parts meet the same compliance standards? A: Yes. Both H11A2 and TIL116X are ROHS3 compliant and REACH unaffected.

Q: What is the operating temperature range for both parts? A: Both parts operate across -55°C to 100°C, providing identical thermal performance.

Q: Are there differences in current transfer ratio performance? A: No. Both parts specify a minimum current transfer ratio of 20% @ 10mA.

Q: Can these parts be used interchangeably in PCB designs? A: Yes. Identical package specifications and electrical characteristics allow direct substitution without PCB layout modifications.
