ILQ1 Optoisolator Transistor Output Equivalent & Substitute Parts

Part Overview

The ILQ1 is a 16-pin through-hole optoisolator with transistor output, manufactured by Isocom Components 2004 LTD. This component provides galvanic isolation up to 5300Vrms with a single channel configuration, designed for DC input applications requiring high-voltage isolation and transistor-based signal detection. The ILQ1 maintains active product status with 4336 units in current inventory. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, application redundancy requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

The ILQ1X qualifies as a parametric equivalent substitute based on identical electrical and mechanical specifications. Substitution criteria are determined by the following key parameters:

Isolation voltage (5300Vrms), single-channel configuration, transistor output topology, current transfer ratio range (20% to 300% @ 10mA), maximum output voltage (50V), maximum output current (50mA per channel), Vce saturation (400mV maximum), and 16-DIP through-hole package format (0.300", 7.62mm pitch).

The ILQ1X maintains all specified electrical performance characteristics and physical form factor compatibility. The primary distinction is packaging format: ILQ1 is supplied in standard packaging, while ILQ1X is supplied in tube packaging. Both variants are manufactured by Isocom Components 2004 LTD and maintain active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both ILQ1 and ILQ1X are active products manufactured by Isocom Components 2004 LTD with identical electrical specifications and mechanical compatibility. Selection between these parts is based on packaging and inventory availability rather than functional performance.

The ILQ1 is suitable for applications requiring standard packaging formats with current inventory of 4336 units. The ILQ1X provides the same electrical and mechanical performance in tube packaging with current inventory of 1206 units.

Both variants maintain ROHS3 compliance, REACH unaffected status, and MSL Level 1 (unlimited moisture sensitivity). Pin configuration, PCB footprint, and electrical performance are identical, ensuring direct substitution capability in 16-DIP through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can ILQ1X be used as a direct replacement for ILQ1 in existing designs?

A: Yes. The ILQ1X is electrically and mechanically identical to the ILQ1. Both components feature the same 16-DIP package format (0.300", 7.62mm pitch), identical pin configuration, and equivalent electrical performance across all specified parameters including isolation voltage, current transfer ratio, output voltage, and output current ratings.

Q: What is the difference between ILQ1 and ILQ1X?

A: The primary difference is packaging format. ILQ1 is supplied in standard packaging, while ILQ1X is supplied in tube packaging. All electrical specifications, mechanical dimensions, and performance characteristics are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both ILQ1 and ILQ1X maintain identical compliance status: ROHS3 compliant, REACH unaffected, and MSL Level 1 (unlimited). Both are active products from the same manufacturer.

Q: What are the critical parameters for substitution in optoisolator applications?

A: Critical substitution parameters include isolation voltage (5300Vrms), number of channels (1), output type (transistor), current transfer ratio range (20% to 300% @ 10mA), maximum output voltage (50V), maximum output current (50mA), and package format (16-DIP through-hole). All these parameters are identical between ILQ1 and ILQ1X.

Q: Can these parts be used in high-temperature applications?

A: Both ILQ1 and ILQ1X are rated for operating temperatures from -25°C to 100°C. Application requirements exceeding this range require alternative component selection.
