HCPL-3760-560E Equivalent & Substitute Parts

Part Overview

The HCPL-3760-560E is an optoisolator with Darlington output manufactured by Broadcom Limited. This component provides galvanic isolation rated at 3750Vrms with a single channel configuration in an 8-DIP Gull Wing surface mount package. The device is designed for AC/DC input applications requiring logic-level output interfacing. The product maintains Active status and is ROHS3 compliant. Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter ranges for optoisolator applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCPL-3760-560E are identified based on the following critical parameters that define functional equivalence in optoisolator applications:

Primary Matching Criteria:

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

Secondary Consideration:

• Voltage - Isolation: Substitute parts rated at 2500Vrms provide reduced isolation voltage compared to the main part's 3750Vrms rating. This represents a functional trade-off where isolation performance is lower but remains within acceptable ranges for many applications not requiring maximum isolation specifications.

The identified substitutes HCPL3700S and HCPL3700SDV maintain all primary matching criteria while differing in isolation voltage rating.

Parameter Comparison

Engineering Selection Recommendations

Component selection between the HCPL-3760-560E and its substitutes is determined by isolation voltage requirements and switching speed specifications:

HCPL-3760-560E is the primary choice for applications requiring 3750Vrms isolation voltage with faster switching characteristics (4.5µs turn-on, 8µs turn-off, 14µs rise time). The device maintains Active product status with ROHS3 compliance.

HCPL3700S and HCPL3700SDV are functionally equivalent substitutes for applications where 2500Vrms isolation voltage is acceptable. Both substitutes maintain Active product status and identical compliance certifications (EAR99, HTSUS 8541.49.8000). The primary difference between these two substitutes is packaging designation: HCPL3700S is supplied in Bulk packaging, while HCPL3700SDV packaging is unspecified in the provided data. Both devices exhibit slower switching response (6µs turn-on, 25µs turn-off, 45µs rise time) compared to the main part.

All three parts share identical output voltage rating (20V maximum), output current capability (30mA per channel), operating temperature range (-40°C to 85°C), and package configuration (8-SMD Gull Wing).

Frequently Asked Questions (FAQ)

Q: Can HCPL3700S or HCPL3700SDV be used as direct replacements for HCPL-3760-560E?

A: Direct replacement is possible only when the application does not require the higher 3750Vrms isolation voltage of the main part. The substitutes provide 2500Vrms isolation, which is lower but maintains all other electrical and mechanical parameters including output voltage, output current, input type compatibility, and package configuration.

Q: What is the primary difference between HCPL3700S and HCPL3700SDV?

A: Both parts are electrically identical with matching isolation voltage (2500Vrms), output specifications, and switching characteristics. The documented difference is packaging type: HCPL3700S is supplied in Bulk packaging, while HCPL3700SDV packaging designation is not specified in the provided data.

Q: How do switching speeds compare between the main part and substitutes?

A: The HCPL-3760-560E provides faster switching response with 4.5µs turn-on time and 14µs rise time. The substitute parts (HCPL3700S and HCPL3700SDV) have slower switching characteristics at 6µs turn-on time and 45µs rise time. Applications with strict timing requirements should verify compatibility with the slower switching response of the substitutes.

Q: Are all three parts RoHS compliant?

A: The HCPL-3760-560E is ROHS3 compliant. RoHS compliance information for HCPL3700S and HCPL3700SDV is not provided in the available data.

Q: Do the substitute parts support the same input signal types?

A: Yes. All three parts support AC and DC input types, providing equivalent input signal compatibility.

Q: What is the inventory status for these parts?

A: HCPL-3760-560E has 928 pieces in stock. HCPL3700S has 1213 pieces in stock. HCPL3700SDV has 746 pieces in stock.
