Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-814-06AE is determined by the following critical parameters:

• Voltage - Isolation: 5000Vrms (exact match required)
• Number of Channels: 1 (exact match required)
• Output Type: Transistor (exact match required)
• Package / Case: 4-DIP (0.300", 7.62mm) (exact match required)
• Voltage - Output (Max): 35V (exact match required)
• Current - Output / Channel: 50mA (exact match required)
• Vce Saturation (Max): 200mV (exact match required)
• Input Type: AC, DC (exact match required)

The LTV-814 manufactured by Lite-On Inc. meets all critical substitution criteria. While the Current Transfer Ratio range differs (20%-300% versus 50%-150%), both parts maintain the same isolation voltage, channel count, output type, package configuration, and maximum output specifications. Operating temperature range extends to 110°C on the LTV-814 compared to 100°C on the HCPL-814-06AE.

Parameter Comparison

Engineering Selection Recommendations

Both the HCPL-814-06AE and LTV-814 are active production components with equivalent compliance certifications. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited moisture sensitivity). The LTV-814 offers an extended operating temperature range to 110°C, providing additional thermal margin in applications operating near the upper temperature limit of the HCPL-814-06AE. Selection between these parts should be based on supply availability, lead time requirements, and application-specific thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the LTV-814 directly replace the HCPL-814-06AE in existing designs?

A: Yes. Both parts share identical package configuration (4-DIP), isolation voltage (5000Vrms), output specifications (35V max, 50mA per channel), and saturation characteristics (200mV max). Through-hole mounting is identical. No PCB layout modifications are required.

Q: What is the significance of the different Current Transfer Ratio ranges?

A: The HCPL-814-06AE specifies 50%-150% CTR while the LTV-814 specifies 20%-300% CTR. Both ranges encompass the typical operating point. Circuit designs accounting for CTR variation across the specified range of either part will function correctly with either component.

Q: Does the extended operating temperature range of the LTV-814 affect compatibility?

A: No. The LTV-814 operating range (-30°C to 110°C) encompasses the HCPL-814-06AE range (-30°C to 100°C). Applications operating within the HCPL-814-06AE temperature specification will operate identically with the LTV-814.

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

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and MSL Level 1 rating. No additional qualification or documentation is required when substituting between these parts.

Q: What are the key parameters that must match for substitution?

A: Isolation voltage (5000Vrms), channel count (1), output type (transistor), package (4-DIP), maximum output voltage (35V), maximum output current (50mA), and saturation voltage (200mV) must remain constant. These parameters define the functional and mechanical compatibility of the substitute part.
