H11A5 Optoisolator Transistor Detector - Equivalent & Substitute Parts

Part Overview

The H11A5 is a single-channel optoisolator with transistor output and base connection, manufactured by Isocom Components 2004 LTD. This component provides galvanic isolation up to 7.5Vpk and is designed for applications requiring DC input signal isolation with transistor-based output control. The part is currently in active production status with 1217 units available in stock. Substitute parts are identified when electrical parameters, mechanical packaging, and compliance certifications remain equivalent across the product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the H11A5 optoisolator is determined by equivalence across the following critical parameters:

• Single-channel configuration with transistor output and base connection
• Isolation voltage rating of 7.5Vpk
• Current transfer ratio minimum of 30% @ 10mA
• Maximum output voltage of 30V and output current of 50mA per channel
• Vce saturation maximum of 400mV
• Operating temperature range of -55°C to 100°C
• 6-DIP through-hole package (0.300", 7.62mm)
• ROHS3 compliance and MSL Level 1 rating

Parts meeting all these parameters within the H11A series are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The H11A5X is a direct parametric equivalent to the H11A5 optoisolator. Both parts are manufactured by Isocom Components 2004 LTD within the H11A series and share identical electrical specifications, mechanical packaging, and compliance certifications. Selection between H11A5 and H11A5X is based on inventory availability and procurement lead times, as all functional and environmental parameters are equivalent. Both parts maintain active production status and ROHS3 compliance with MSL Level 1 rating, suitable for standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can H11A5X be used as a direct replacement for H11A5?

A: Yes. The H11A5X meets all electrical and mechanical specifications of the H11A5, including isolation voltage, current transfer ratio, output voltage and current ratings, saturation characteristics, operating temperature range, and 6-DIP package dimensions. Both parts are ROHS3 compliant with identical MSL ratings.

Q: Are there any differences in pin configuration between H11A5 and H11A5X?

A: No. Both parts use the 6-DIP (0.300", 7.62mm) through-hole package with identical pin assignments and base output configuration.

Q: What determines if a part is a valid substitute for the H11A5?

A: Valid substitutes must maintain equivalence across isolation voltage (7.5Vpk), single-channel transistor output with base connection, current transfer ratio (30% minimum @ 10mA), maximum output voltage (30V), maximum output current (50mA), Vce saturation (400mV maximum), operating temperature range (-55°C to 100°C), and 6-DIP through-hole packaging.

Q: Are both H11A5 and H11A5X available for immediate shipment?

A: Both parts are in active production with current stock availability. H11A5 has 1217 units and H11A5X has 1203 units available as new original components.

Q: Do H11A5 and H11A5X have different compliance certifications?

A: No. Both parts carry identical ROHS3 compliance, MSL Level 1 rating, REACH Unaffected status, and the same ECCN and HTSUS classifications.
