ISQ5 Optoisolator Equivalent & Substitute Parts

Part Overview

The ISQ5 is a quad-channel optoisolator with transistor output manufactured by Isocom Components 2004 LTD. This 16-pin DIP component provides galvanic isolation up to 5300Vrms across four independent channels, with each channel capable of delivering up to 50mA output current. The part is currently in active production status with 4034 units in stock. Substitute parts are identified when inventory constraints, supply chain disruptions, or procurement requirements necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISQ5 optoisolator is determined by strict equivalence across the following critical parameters:

• Number of Channels: 4 channels required
• Voltage - Isolation: 5300Vrms minimum
• Current Transfer Ratio: 50% (Min) @ 10mA and 400% (Max) @ 10mA
• Output Type: Transistor output configuration
• Voltage - Output (Max): 70V
• Current - Output / Channel: 50mA per channel
• Rise / Fall Time: 2.6µs rise, 2.2µs fall
• Package / Case: 16-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Operating Temperature Range: -25°C ~ 100°C

The ISQ5X meets all specified parameters and qualifies as a parametric equivalent substitute. Both parts are manufactured by the same supplier, share identical electrical characteristics, and are housed in the same physical package configuration.

Parameter Comparison

Engineering Selection Recommendations

Both ISQ5 and ISQ5X are active production components manufactured by Isocom Components 2004 LTD with identical electrical specifications and package configurations. Selection between these parts is based on availability and procurement requirements rather than technical differentiation.

ISQ5 carries 4034 units in current inventory, while ISQ5X maintains 819 units in stock. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The through-hole 16-DIP package supports standard PCB assembly processes without requiring specialized equipment or design modifications.

Frequently Asked Questions (FAQ)

Q: Can ISQ5X be used as a direct replacement for ISQ5 in existing designs?

A: Yes. The ISQ5X is a parametric equivalent with identical electrical characteristics, isolation voltage, output current ratings, timing specifications, and package dimensions. No circuit modifications or PCB redesign are required.

Q: Are there any differences in the 16-DIP package between ISQ5 and ISQ5X?

A: No. Both parts use the same 16-DIP (0.300", 7.62mm) package configuration with through-hole mounting. Pin assignments and mechanical dimensions are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. ISQ5 and ISQ5X are both ROHS3 compliant and REACH unaffected. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: What is the isolation voltage specification for these optoisolators?

A: Both ISQ5 and ISQ5X provide 5300Vrms galvanic isolation across all four channels, suitable for high-voltage isolation applications.

Q: Are there any temperature operating range differences?

A: No. Both parts operate across the identical temperature range of -25°C to 100°C.

Q: What is the maximum output current per channel?

A: Each of the four channels in both ISQ5 and ISQ5X can deliver a maximum of 50mA output current with a maximum output voltage of 70V.
