Key Parameters

Substitute Part Grouping Explanation

The H11D2 has two parametric equivalents within the H11D series: H11D1X and H11D2X. These parts are substitutable based on the following criteria:

Substitution-Determining Parameters:

• Single channel configuration
• 7.5Vpk isolation voltage
• 20% minimum current transfer ratio at 10mA input
• Transistor output with base connection
• 300V maximum output voltage
• 100mA maximum output current per channel
• 6-DIP through-hole package (0.300", 7.62mm)
• DC input type
• Operating temperature range: -55°C to 100°C

All three parts (H11D2, H11D1X, H11D2X) share identical electrical specifications and mechanical packaging, making them interchangeable for applications requiring these parameters.

Parameter Comparison

Engineering Selection Recommendations

All three parts—H11D2, H11D1X, and H11D2X—are active products manufactured by Isocom Components 2004 LTD with identical electrical and mechanical specifications. Selection between these parts should be based on availability and procurement requirements:

• H11D2: Primary part number with highest inventory (1467 units)
• H11D1X: Parametric equivalent with 1167 units available
• H11D2X: Parametric equivalent with 745 units available

All parts comply with ROHS3 and are REACH unaffected, meeting current regulatory requirements for industrial and commercial applications. Through-hole 6-DIP packaging supports standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can H11D1X and H11D2X be used interchangeably with H11D2?

A: Yes. All three parts share identical electrical parameters, isolation voltage, output current ratings, and 6-DIP package specifications. They are direct parametric equivalents.

Q: What determines substitutability for the H11D2 optoisolator?

A: Substitutability is determined by matching: single-channel configuration, 7.5Vpk isolation voltage, 20% minimum current transfer ratio, transistor output with base connection, 300V maximum output voltage, 100mA output current, and 6-DIP through-hole package. All substitute parts meet these criteria.

Q: Are there any compliance differences between H11D2, H11D1X, and H11D2X?

A: No. All three parts carry identical ROHS3 compliance and REACH unaffected status.

Q: Does package size differ between these part numbers?

A: No. All three parts use the same 6-DIP (0.300", 7.62mm) through-hole package, ensuring identical PCB footprint and mounting compatibility.

Q: What is the operating temperature range for these optoisolators?

A: The operating temperature range for H11D2, H11D1X, and H11D2X is -55°C to 100°C.
