Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the H11AA2 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution criteria include:

• Identical isolation voltage rating (7.5Vpk)
• Matching current transfer ratio minimum specification (10% @ 10mA)
• Equivalent output type (Transistor with Base)
• Same maximum output voltage (35V) and output current per channel (50mA)
• Identical forward voltage and saturation characteristics
• Matching operating temperature range (-30°C ~ 100°C)
• Compatible package format (6-DIP, 0.300", 7.62mm)
• Equivalent compliance certifications (ROHS3, REACH Unaffected)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The H11AA2X qualifies as a direct parametric equivalent to the H11AA2. Both parts are manufactured by Isocom Components 2004 LTD within the H11A series and maintain identical electrical specifications, mechanical dimensions, and compliance certifications. Selection between these parts is determined by availability and inventory status. The H11AA2 maintains higher stock levels (6924 units) compared to the H11AA2X (868 units). Both parts carry active product status and meet ROHS3 and REACH compliance requirements, ensuring regulatory compliance in end applications.

Frequently Asked Questions (FAQ)

Q: Can H11AA2X be used as a direct replacement for H11AA2?

A: Yes. The H11AA2X is a parametric equivalent with identical electrical specifications, output characteristics, isolation voltage, current ratings, and package format. Direct substitution is supported without circuit modification.

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

A: No. Both parts carry identical ROHS3 compliance status and REACH Unaffected designation. Moisture sensitivity level is equivalent at MSL 1 (Unlimited).

Q: Do these parts share the same pinout and mechanical compatibility?

A: Yes. Both parts use the 6-DIP (0.300", 7.62mm) package with identical through-hole mounting specifications, ensuring mechanical and electrical compatibility on PCBs designed for either part number.

Q: What determines substitutability for H11AA2 optoisolators?

A: Substitutability is determined by matching isolation voltage (7.5Vpk), current transfer ratio minimum (10% @ 10mA), output type (Transistor with Base), maximum output voltage (35V), output current per channel (50mA), operating temperature range (-30°C ~ 100°C), and package format (6-DIP). All these parameters must be identical for direct substitution.

Q: Are there inventory considerations when selecting between H11AA2 and H11AA2X?

A: Yes. The H11AA2 has significantly higher inventory availability (6924 units) compared to H11AA2X (868 units). Selection may be influenced by project lead times and supply chain requirements.
