Substitute Part Grouping Explanation

Substitute parts for the H11D2G are identified within the H11D series based on strict parametric equivalence. The substitution criteria are defined by the following parameters that must remain identical:

• Number of Channels: 1
• Voltage - Isolation: 7.5Vpk
• Current Transfer Ratio (Min): 20% @ 10mA
• Output Type: Transistor with Base
• Voltage - Output (Max): 300V
• Current - Output / Channel: 100mA
• Voltage - Forward (Vf) (Typ): 1.2V
• Current - DC Forward (If) (Max): 60mA
• Vce Saturation (Max): 400mV
• Operating Temperature: -55°C ~ 100°C
• Package / Case: 6-DIP (0.400", 10.16mm)
• Mounting Type: Through Hole

All substitute parts maintain these exact specifications, ensuring functional interchangeability in circuit designs. Variations in part numbering within the H11D series reflect manufacturing or packaging distinctions that do not affect electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—H11D2G, H11D1XG, and H11D2XG—are functionally equivalent optoisolators within the H11D series. Selection between these parts is based on availability and product status rather than electrical or mechanical differences.

Current inventory status:

• H11D2G: 1101 Pcs New Original In Stock
• H11D1XG: 980 Pcs New Original In Stock
• H11D2XG: 1090 Pcs New Original In Stock

All parts maintain Active product status and full compliance with ROHS3 and REACH standards. The 6-DIP through-hole package ensures compatibility with standard PCB layouts. The -55°C to 100°C operating temperature range supports industrial and commercial applications. Selection should prioritize availability and lead time requirements, as electrical performance and compliance certifications are identical across all three part numbers.

Frequently Asked Questions (FAQ)

Q: Can H11D1XG or H11D2XG be used as direct replacements for H11D2G?

A: Yes. All three parts share identical electrical specifications, including isolation voltage, current transfer ratio, output voltage rating, and switching characteristics. The 6-DIP package and through-hole mounting are identical, enabling direct PCB substitution without circuit redesign.

Q: What determines whether a part qualifies as a substitute for H11D2G?

A: Substitution is based on matching all critical parameters: single-channel configuration, 7.5Vpk isolation voltage, 20% minimum current transfer ratio at 10mA, transistor output with base connection, 300V maximum output voltage, 100mA output current per channel, 1.2V typical forward voltage, 60mA maximum DC forward current, 400mV maximum Vce saturation, -55°C to 100°C operating temperature range, and 6-DIP through-hole package. Any deviation in these parameters disqualifies a part from substitution.

Q: Are there differences in packaging or lead configuration between these parts?

A: No. All three parts use identical 6-DIP (0.400", 10.16mm) packaging with through-hole mounting. PCB footprints and component placement are interchangeable.

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

A: Yes. H11D2G, H11D1XG, and H11D2XG are all ROHS3 Compliant and REACH Unaffected, with Moisture Sensitivity Level 1 (Unlimited). Compliance certifications are identical across all three part numbers.

Q: What is the significance of the part number suffix differences (G, XG)?

A: Part number suffixes reflect manufacturing or packaging distinctions within the H11D series. These variations do not affect electrical performance, mechanical compatibility, or compliance status. All parts remain functionally equivalent for circuit applications.
