• Current transfer ratio range: 100% to 500% @ 10mA
• Output configuration: Single-channel transistor output
• Maximum output voltage: 70V
• Maximum output current: 50mA per channel
• Saturation voltage: 400mV maximum
• Switching speed: 2µs rise and fall times
• Package type: 16-DIP through-hole configuration
• Operating temperature range: -25°C to 100°C
• Compliance certifications: ROHS3, MSL Level 1

Only parts matching all specified parameters are listed as direct substitutes. No parameter relaxation or tolerance variation is applied.

Parameter Comparison

Engineering Selection Recommendations

The ILQ2G and ILQ2XG are parametrically equivalent optoisolators. Both parts maintain identical electrical specifications across isolation voltage, current transfer ratio, output characteristics, and switching performance. Both components are in active production status with ROHS3 compliance and MSL Level 1 rating, indicating equivalent environmental and regulatory standing.

Selection between these parts is based on inventory availability and supply chain considerations. The ILQ2G currently has 836 units in stock, while the ILQ2XG has 1140 units available. Both parts are suitable for direct substitution in applications requiring 5300Vrms isolation with single-channel transistor output in 16-DIP through-hole packages.

Frequently Asked Questions (FAQ)

Q: Can ILQ2XG replace ILQ2G in existing designs?

A: Yes. The ILQ2XG is a parametric equivalent with identical electrical and mechanical specifications. No circuit modifications are required for substitution.

Q: Are there any package differences between ILQ2G and ILQ2XG?

A: No. Both parts use the same 16-DIP (0.400", 10.16mm) through-hole package configuration with identical pin assignments and mechanical dimensions.

Q: What determines if a part qualifies as a substitute?

A: Substitution requires exact equivalence across isolation voltage (5300Vrms), current transfer ratio (100-500% @ 10mA), output voltage (70V max), output current (50mA max), saturation voltage (400mV max), switching speed (2µs), operating temperature range (-25°C to 100°C), and package type (16-DIP through-hole).

Q: Are both parts RoHS compliant?

A: Yes. Both ILQ2G and ILQ2XG are ROHS3 compliant with MSL Level 1 rating, indicating unlimited moisture sensitivity protection.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs. Selection should be based on supplier availability, lead time, and inventory status. Both parts are in active production with equivalent compliance certifications.
