Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISP817BLG is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating: 5300Vrms
• Number of channels: 1
• Output type: Transistor
• Current transfer ratio range: 200% to 600% @ 5mA
• Maximum output voltage: 80V
• Maximum output current per channel: 50mA
• Maximum Vce saturation: 200mV
• Operating temperature range: -55°C to 110°C
• Package type: 4-DIP (0.400", 10.16mm)
• Mounting type: Through Hole

The ISP817XBLG meets all specified parameters and is classified as a parametric equivalent. Both parts share identical electrical characteristics, thermal specifications, and physical packaging, enabling direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both ISP817BLG and ISP817XBLG are active production components manufactured by Isocom Components 2004 LTD. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. The ISP817XBLG carries higher inventory availability (1224 pieces) compared to the ISP817BLG (1071 pieces), which may influence procurement decisions based on lead time and supply chain requirements. Selection between these parts should be based on inventory availability and delivery schedules, as electrical and mechanical specifications are identical.

Frequently Asked Questions (FAQ)

Q: Can ISP817XBLG replace ISP817BLG in existing designs?

A: Yes. Both parts are parametric equivalents with identical isolation voltage, current transfer ratios, output specifications, operating temperature range, and 4-DIP package configuration. Direct substitution is supported without circuit modification.

Q: Are there any differences in compliance or certifications?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1 - Unlimited). Regulatory and environmental certifications are equivalent.

Q: What determines substitution eligibility for optoisolators in this category?

A: Substitution requires matching isolation voltage rating, number of channels, output type, current transfer ratio specifications, maximum output voltage and current, Vce saturation characteristics, operating temperature range, and physical package dimensions. All these parameters must be identical for direct substitution.

Q: Does packaging differ between these parts?

A: No. Both ISP817BLG and ISP817XBLG use 4-DIP (0.400", 10.16mm) through-hole packaging with identical pin configuration and mounting requirements.

Q: What is the primary reason to consider a substitute part?

A: Substitute parts are selected based on inventory availability, delivery lead times, and supply chain optimization while maintaining identical electrical performance and physical compatibility.
