Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCPL-3700-360E are identified based on the following allowed electrical and mechanical parameters:

• Number of Channels: Must equal 1
• Output Type: Must be Darlington
• Voltage - Output (Max): Must equal or exceed 20V
• Current - Output / Channel: Must equal or exceed 30mA
• Input Type: Must support AC, DC
• Operating Temperature Range: Must cover -40°C ~ 85°C
• Mounting Type: Must be Surface Mount
• Package / Case: Must be 8-SMD, Gull Wing
• Product Status: Must be Active
• Compliance: Must maintain RoHS3 compliance

The substitute parts identified (HCPL3700S and HCPL3700SDV) meet these core functional and mechanical requirements. The isolation voltage differs (2500Vrms versus 3750Vrms), which represents a reduced isolation specification. Timing characteristics also differ, with substitute parts exhibiting longer turn-on/turn-off and rise/fall times.

Parameter Comparison

Engineering Selection Recommendations

Both HCPL3700S and HCPL3700SDV are active production components manufactured by Fairchild Semiconductor and maintain RoHS3 compliance. These parts are functionally equivalent to the HCPL-3700-360E within the scope of single-channel Darlington optoisolator applications requiring 8-SMD Gull Wing surface mount packaging.

Component selection between the main part and substitutes depends on application-specific isolation voltage requirements. The HCPL-3700-360E provides 3750Vrms isolation, while both substitute parts provide 2500Vrms isolation. Applications requiring the higher isolation specification must use the HCPL-3700-360E. Applications tolerant of 2500Vrms isolation can utilize either substitute part.

Timing performance differs between the main part and substitutes. The HCPL-3700-360E exhibits faster switching characteristics (4µs turn-on, 20µs rise time) compared to the substitute parts (6µs turn-on, 45µs rise time). Applications with timing-critical signal processing requirements must account for these differences.

Frequently Asked Questions (FAQ)

Q: Can HCPL3700S and HCPL3700SDV be used interchangeably with HCPL-3700-360E?

A: Both substitute parts share identical electrical output specifications (20V maximum, 30mA per channel) and mechanical packaging (8-SMD Gull Wing). However, the isolation voltage is reduced from 3750Vrms to 2500Vrms, and switching times are slower. Substitution is valid only when the application isolation voltage requirement does not exceed 2500Vrms and timing performance is acceptable.

Q: What is the difference between HCPL3700S and HCPL3700SDV?

A: Both parts are manufactured by Fairchild Semiconductor and share identical electrical specifications and timing characteristics. The primary difference is packaging designation. HCPL3700S is supplied in Bulk packaging, while HCPL3700SDV packaging is not specified in the provided data. Both are available in 8-SMD Gull Wing case format.

Q: Are all three parts RoHS3 compliant?

A: The HCPL-3700-360E is confirmed RoHS3 compliant. RoHS3 compliance status for HCPL3700S and HCPL3700SDV is not specified in the provided data.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: single-channel configuration, Darlington output type, minimum 20V output voltage rating, minimum 30mA output current per channel, AC/DC input capability, -40°C to 85°C operating temperature range, surface mount mounting type, and 8-SMD Gull Wing package format. Isolation voltage and timing characteristics are secondary parameters that may differ between the main part and substitutes.

Q: Which part should be selected for high-isolation applications?

A: The HCPL-3700-360E must be selected for applications requiring isolation voltage above 2500Vrms. The substitute parts are limited to 2500Vrms maximum isolation.
