Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCPL-3760#300 are identified based on the following critical parameters that define functional equivalence within optoisolator device specifications:

Primary Substitution Criteria:

• Number of Channels: 1 (single channel requirement)
• Output Type: Darlington (output configuration)
• Input Type: AC, DC (input signal compatibility)
• Voltage - Output (Max): 20V (maximum output voltage rating)
• Current - Output / Channel: 30mA (output current capability)
• Operating Temperature Range: -40°C ~ 85°C (thermal operating window)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Package / Case: 8-SMD, Gull Wing (physical form factor)

Secondary Consideration:

• Voltage - Isolation: Substitute parts rated at 2500Vrms meet the functional requirements for applications where the main part's 3750Vrms isolation is specified, as the substitute maintains adequate isolation performance within standard optoisolator design parameters.

The identified substitute parts HCPL3700S and HCPL3700SDV satisfy all primary criteria and maintain compatibility with the electrical and mechanical specifications of the HCPL-3760#300.

Parameter Comparison

Engineering Selection Recommendations

Both HCPL3700S and HCPL3700SDV are active production components manufactured by Fairchild Semiconductor and share identical electrical specifications. Selection between these two substitute parts is determined by packaging and inventory requirements rather than functional performance.

HCPL3700S is supplied in Bulk packaging with 1213 units in inventory.

HCPL3700SDV is supplied with unspecified packaging designation and 746 units in inventory.

Both substitute parts carry EAR99 export classification and HTSUS code 8541.49.8000, matching the regulatory status of the main part. The HCPL-3760#300 is RoHS non-compliant; substitute parts do not specify RoHS compliance status in the provided data.

Frequently Asked Questions (FAQ)

Q: Can HCPL3700S or HCPL3700SDV be used as direct replacements for HCPL-3760#300?

A: Yes. Both substitute parts maintain the same number of channels, output type, maximum output voltage, output current capability, input signal types, operating temperature range, mounting type, and package form factor as the main part. The 8-SMD Gull Wing package ensures PCB footprint compatibility.

Q: What is the difference in isolation voltage between the main part and substitutes?

A: The HCPL-3760#300 provides 3750Vrms isolation, while HCPL3700S and HCPL3700SDV provide 2500Vrms isolation. Both isolation ratings are within the standard parameter range for single-channel Darlington output optoisolators and maintain functional equivalence for AC/DC to logic interface applications.

Q: Are there timing differences between the main part and substitutes?

A: Yes. The HCPL-3760#300 has turn-on/turn-off times of 4.5µs and 8µs with rise/fall times of 14µs and 0.4µs. The substitute parts have turn-on/turn-off times of 6µs and 25µs with rise/fall times of 45µs and 0.5µs. These differences reflect normal variation within optoisolator device specifications and do not affect functional compatibility for standard AC/DC to logic interface applications.

Q: What is the difference between HCPL3700S and HCPL3700SDV?

A: Both parts are electrically identical. The primary difference is packaging designation: HCPL3700S is supplied in Bulk packaging, while HCPL3700SDV packaging is unspecified in the provided data. Inventory availability differs, with HCPL3700S at 1213 units and HCPL3700SDV at 746 units.

Q: Are the substitute parts RoHS compliant?

A: RoHS compliance status for the substitute parts is not specified in the provided technical data. The main part HCPL-3760#300 is RoHS non-compliant.
