Substitute Part Grouping Explanation

Substitution of the HCPL-814-00AE is permissible with parts meeting the following criteria:

• Isolation voltage of 5000Vrms or greater
• Single channel configuration
• Transistor output topology
• Maximum output current of 50mA or greater
• Maximum output voltage of 35V or greater
• 4-DIP package form factor with 0.300" (7.62mm) pitch
• Through-hole mounting compatibility
• Operating temperature range that encompasses or exceeds -30°C to 100°C
• ROHS3 compliance and REACH unaffected status

The LTV-814 manufactured by Lite-On Inc. satisfies all substitution criteria within these electrical and mechanical boundaries.

Parameter Comparison

Engineering Selection Recommendations

Both the HCPL-814-00AE and LTV-814 are active production components with ROHS3 compliance and REACH unaffected status, making them suitable for applications subject to environmental regulations. The LTV-814 provides an extended operating temperature range to 110°C compared to the HCPL-814-00AE at 100°C maximum. Both components maintain identical isolation voltage, output current capacity, output voltage limits, and package form factor. Selection between these parts should be based on supply availability, lead time requirements, and specific application temperature operating conditions within the stated ranges.

Frequently Asked Questions (FAQ)

Q: Can the LTV-814 directly replace the HCPL-814-00AE in existing designs?

A: Yes, the LTV-814 is a direct substitute. Both components share identical package form factor (4-DIP), isolation voltage (5000Vrms), output current rating (50mA), output voltage limit (35V), and saturation characteristics (200mV maximum). Pin configuration and electrical interface are compatible.

Q: What is the difference in Current Transfer Ratio between these parts?

A: The HCPL-814-00AE specifies a Current Transfer Ratio of 50% to 150% at 1mA input current. The LTV-814 specifies 20% to 300% at 1mA. Both ranges overlap, but the LTV-814 permits wider variation. Circuit designs must account for the specified minimum and maximum CTR values of the selected part.

Q: Are there temperature operating range considerations for substitution?

A: The HCPL-814-00AE operates from -30°C to 100°C. The LTV-814 extends to 110°C maximum. If the application requires operation above 100°C, the LTV-814 is the appropriate selection. For applications within -30°C to 100°C, both parts are suitable.

Q: Do both parts require the same PCB footprint?

A: Yes. Both components use the 4-DIP package with 0.300" (7.62mm) pitch and through-hole mounting. PCB layouts designed for the HCPL-814-00AE accommodate the LTV-814 without modification.

Q: Are regulatory certifications equivalent between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. They meet equivalent environmental and regulatory requirements for applications subject to these standards.
