HCPL-3700-560E Equivalent & Substitute Parts

Part Overview

The HCPL-3700-560E 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 to logic interface applications and maintains active product status with full RoHS3 compliance and REACH unaffected certification.

Substitute parts are identified when equivalent functional performance can be maintained within the allowed electrical and mechanical parameter ranges for optoisolator applications. The primary consideration for substitution involves isolation voltage rating, output characteristics, and package compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCPL-3700-560E are identified based on the following criteria:

Electrical Compatibility Parameters:

• Single channel Darlington output configuration
• Maximum output voltage of 20V
• Output current capacity of 30mA per channel
• AC/DC input type capability
• Operating temperature range of -40°C to 85°C
• Surface mount package with 8-SMD Gull Wing configuration

Substitution Logic: The identified substitute parts (HCPL3700S and HCPL3700SDV) maintain functional equivalence in channel count, output type, voltage rating, current capacity, input type, temperature range, and package form factor. These parts are classified as manufacturer-recommended substitutes and share the same base product number (HCPL-3700) with the main part, indicating design-level compatibility within the optoisolator product family.

Parameter Comparison

Engineering Selection Recommendations

HCPL-3700-560E (Primary Part): Broadcom Limited manufacture with 3750Vrms isolation rating. Active product status with ROHS3 compliance and REACH unaffected certification. Moisture sensitivity level 1 indicates unlimited shelf life capability.

HCPL3700S (Substitute): Fairchild Semiconductor manufacture with 2500Vrms isolation rating. Active product status with EAR99 export classification. Bulk packaging available. Timing characteristics show increased turn-on/turn-off and rise/fall times compared to the main part.

HCPL3700SDV (Substitute): Fairchild Semiconductor manufacture with 2500Vrms isolation rating. Active product status with EAR99 export classification. Timing characteristics identical to HCPL3700S. Both Fairchild substitutes maintain electrical and mechanical compatibility within the optoisolator product family.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the main part and substitute parts? A: The HCPL-3700-560E features a 3750Vrms isolation rating, while both HCPL3700S and HCPL3700SDV provide 2500Vrms isolation. All three parts maintain identical output voltage, current capacity, channel count, input type, operating temperature range, and package configuration.

Q: Are the timing characteristics equivalent across all three parts? A: No. The HCPL-3700-560E specifies turn-on/turn-off times of 4µs and 10µs with rise/fall times of 20µs and 0.3µs. Both Fairchild substitutes specify 6µs and 25µs turn-on/turn-off times with 45µs and 0.5µs rise/fall times. Applications requiring faster switching response should account for these differences.

Q: Are the package configurations identical? A: Yes. All three parts use 8-SMD Gull Wing surface mount packages, enabling direct board-level substitution without layout modifications.

Q: What compliance certifications apply to these parts? A: The HCPL-3700-560E is ROHS3 compliant and REACH unaffected. All three parts share EAR99 export classification and HTSUS code 8541.49.8000.

Q: Can HCPL3700S and HCPL3700SDV be used interchangeably? A: Yes. Both parts are manufactured by Fairchild Semiconductor with identical electrical specifications, timing characteristics, and package configuration. The primary difference is packaging format (Bulk versus unspecified).
