Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IX3180GSTR must satisfy the following critical parameters to ensure functional equivalence:

• Single-channel optical coupling gate driver topology
• 3750Vrms isolation voltage rating
• 10kV/µs common mode transient immunity
• 2.5A peak output current capability
• 200ns maximum propagation delay (both rising and falling edges)
• 65ns maximum pulse width distortion
• 10V to 20V output supply voltage range
• -40°C to 100°C operating temperature range
• Surface mount package configuration
• ROHS3 compliance and REACH unaffected status

The HCPL-3180-500E from Broadcom Limited meets all specified electrical and mechanical parameters. This part maintains identical isolation voltage, propagation delay, pulse width distortion, rise/fall time characteristics, output current ratings, and supply voltage requirements. Both components are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-3180-500E is the direct functional equivalent for the obsolete IX3180GSTR. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The HCPL-3180-500E maintains active product status with Broadcom Limited, ensuring ongoing availability and supply chain support.

All electrical parameters—isolation voltage, propagation delay, pulse width distortion, output current ratings, and operating temperature range—are identical between the two parts. This equivalence supports direct substitution in existing designs without circuit modification or performance degradation.

The HCPL-3180-500E is approved by CSA and UR agencies, providing additional certification coverage compared to the original part's UR approval alone.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-3180-500E directly replace the IX3180GSTR in existing designs?

A: Yes. The HCPL-3180-500E meets all electrical and mechanical specifications of the IX3180GSTR, including isolation voltage, propagation delay, output current, and operating temperature range. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The IX3180GSTR uses an 8-SMD Gull Wing package, while the HCPL-3180-500E uses an 8-DIP Gull Wing package. Both are surface mount configurations. The HCPL-3180-500E is also actively manufactured by Broadcom, whereas the IX3180GSTR is obsolete.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The HCPL-3180-500E carries CSA and UR approvals, while the IX3180GSTR carries UR approval. Both meet current regulatory standards.

Q: What parameters determine substitution eligibility for this gate driver?

A: Critical parameters include isolation voltage (3750Vrms), propagation delay (200ns maximum), pulse width distortion (65ns maximum), peak output current (2.5A), common mode transient immunity (10kV/µs), and output supply voltage range (10V to 20V). All must match or exceed the original specification.

Q: Is the HCPL-3180-500E available in higher inventory quantities?

A: Yes. The HCPL-3180-500E has 4530 pieces in stock compared to 851 pieces for the IX3180GSTR, providing improved supply chain availability.
