Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISP817BLSM are identified based on strict equivalence across the following critical parameters:

• Voltage - Isolation: 5300Vrms
• Number of Channels: 1
• Current Transfer Ratio: 200% (Min) @ 5mA and 600% (Max) @ 5mA
• Output Type: Transistor
• Voltage - Output (Max): 80V
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 200mV
• Rise / Fall Time: 4µs, 3µs
• Package / Case: 4-SMD (0.300", 7.62mm)
• Operating Temperature: -55°C ~ 110°C

The ISP817XBLSM maintains identical electrical and mechanical specifications across all these parameters, qualifying it as a parametric equivalent within the ISP817 series.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can ISP817XBLSM be used as a direct replacement for ISP817BLSM?

A: Yes. The ISP817XBLSM is a parametric equivalent with identical isolation voltage (5300Vrms), current transfer ratio (200%-600% @ 5mA), output specifications (80V max, 50mA per channel), switching characteristics (4µs rise, 3µs fall), and 4-SMD package configuration. Both parts are manufactured by Isocom Components 2004 LTD within the ISP817 series.

Q: Are there any differences in compliance or certifications?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited). Both are active production components.

Q: What determines substitutability for ISP817 series optoisolators?

A: Substitutability is determined by matching isolation voltage rating, number of channels, current transfer ratio range, maximum output voltage and current, saturation voltage, switching speed characteristics, operating temperature range, and surface mount package dimensions.

Q: Does the part number suffix affect electrical performance?

A: No. The ISP817BLSM and ISP817XBLSM suffixes do not indicate electrical performance differences. Both parts maintain identical specifications across all measured parameters.
