Key Parameters

Substitute Part Grouping Explanation

Substitution for the HCPL-314J#500 is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 5000Vrms minimum
• Channel Configuration: 2-channel gate driver topology
• Output Current Capability: 600mA peak output current
• Common Mode Transient Immunity: 25kV/µs minimum
• Propagation Delay: 700ns maximum (tpLH and tpHL)
• Output Supply Voltage Range: 10V ~ 30V
• Operating Temperature Range: -40°C ~ 100°C
• Package Type: 16-SOIC surface mount
• Technology: Optical coupling isolation

The HCPL-314J-500E is a direct functional equivalent manufactured by Broadcom Limited under the same base product number (HCPL-314) with identical electrical specifications and package configuration. The primary distinction is product status and packaging format availability.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-314J-500E is the primary substitute for the discontinued HCPL-314J#500. Both parts share identical electrical specifications, isolation ratings, and package geometry, ensuring direct functional compatibility in existing circuit designs.

The HCPL-314J-500E offers the advantage of active product status with current manufacturing support and improved regulatory compliance (ROHS3 Compliant versus RoHS non-compliant). Packaging availability is expanded to include Cut Tape and Digi-Reel formats, supporting both prototype and production volume requirements.

For applications requiring continued use of the original HCPL-314J#500 specification, the HCPL-314J-500E provides equivalent performance without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can HCPL-314J-500E be used as a direct replacement for HCPL-314J#500?

A: Yes. Both parts are manufactured by Broadcom Limited under the same base product number (HCPL-314) and share identical electrical specifications, isolation voltage, output current capability, propagation delay, and 16-SOIC package configuration. No circuit modifications are required.

Q: What is the difference between HCPL-314J#500 and HCPL-314J-500E?

A: The primary differences are product status and packaging format. HCPL-314J#500 is discontinued at DiGi Electronics, while HCPL-314J-500E is active. HCPL-314J-500E is available in Cut Tape and Digi-Reel packaging formats and meets ROHS3 compliance, whereas HCPL-314J#500 is RoHS non-compliant.

Q: Are the isolation voltage and output current specifications identical?

A: Yes. Both parts provide 5000Vrms isolation, 600mA peak output current, 500mA output high current, and operate across the same -40°C to 100°C temperature range with identical propagation delay and rise/fall time characteristics.

Q: What packaging formats are available for the substitute part?

A: HCPL-314J-500E is available in Cut Tape (CT) and Digi-Reel packaging formats, supporting both prototype development and production volume applications.

Q: Does the substitute part meet the same regulatory approvals?

A: Yes. HCPL-314J-500E carries the same approval agencies (CSA, IEC/EN/DIN, UR) as the original HCPL-314J#500, with the addition of ROHS3 compliance.
