Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISD1G are identified based on strict equivalence across the following critical parameters:

• Number of channels: 2
• Isolation voltage: 5300Vrms
• Current transfer ratio range: 20% to 300% @ 10mA
• Output type: Transistor
• Maximum output voltage: 50V
• Maximum output current per channel: 50mA
• Input forward voltage: 1.2V typical
• Maximum forward current: 50mA
• Operating temperature range: -25°C to 100°C
• Package type: 8-DIP (0.400", 10.16mm)
• Mounting: Through Hole
• Compliance: ROHS3 Compliant

The ISD1XG meets all these parameters and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ISD1G and ISD1XG are active production components from Isocom Components 2004 LTD with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and supply chain considerations. Both parts maintain ROHS3 compliance and are suitable for applications requiring dual-channel galvanic isolation at 5300Vrms with transistor output configuration. The through-hole 8-DIP package ensures compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ISD1XG be used as a direct replacement for ISD1G?

A: Yes. The ISD1XG is a parametric equivalent with identical electrical characteristics, isolation voltage, current transfer ratio specifications, output ratings, and 8-DIP through-hole package configuration.

Q: Are there any differences in compliance or certifications between ISD1G and ISD1XG?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry the same ECCN and HTSUS classifications. No compliance differences exist.

Q: What determines substitutability for the ISD1G optoisolator?

A: Substitutability is determined by matching the dual-channel configuration, 5300Vrms isolation voltage, 20-300% current transfer ratio range, 50V maximum output voltage, 50mA per-channel output current, 1.2V forward voltage, 50mA maximum forward current, -25°C to 100°C operating temperature range, and 8-DIP through-hole package specification.

Q: Can these parts be used in surface-mount applications?

A: No. Both ISD1G and ISD1XG are specified for through-hole mounting only in 8-DIP package configuration. Surface-mount alternatives would require different package types not covered by this substitution group.

Q: What is the inventory status for these substitute parts?

A: ISD1G has 884 units in stock, and ISD1XG has 842 units in stock, both listed as new original components.
