Key Parameters

Substitute Part Grouping Explanation

Substitution of the IX3180G is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating: 3750Vrms minimum
• Single-channel gate driver configuration
• Peak output current capability: 2.5A
• Common mode transient immunity: 10kV/µs or greater
• Propagation delay specifications: 200ns maximum
• Pulse width distortion: 65ns maximum
• 8-DIP through-hole package footprint
• Output supply voltage range: 10V – 20V
• Operating temperature range: -40°C to +100°C

The HCPL-3180-000E from Broadcom Limited meets all specified electrical and mechanical parameters, establishing it as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-3180-000E is the direct equivalent for IX3180G replacement. Selection is based on:

• Complete electrical parameter equivalence across all specified ratings
• Identical 8-DIP through-hole package footprint, enabling direct PCB substitution
• Active product status with ongoing manufacturer support, addressing the obsolescence of the IX3180G
• ROHS3 compliance maintained in both original and substitute
• Broadcom's HCPL-3180-000E carries CSA and UR certifications, providing expanded regulatory coverage compared to the original UR-only approval
• Tube packaging of the substitute supports standard component handling and storage protocols

Frequently Asked Questions (FAQ)

Q: Can the HCPL-3180-000E be used as a direct replacement for the IX3180G in existing designs?

A: Yes. The HCPL-3180-000E is electrically and mechanically equivalent. The 8-DIP through-hole package footprint is identical, and all electrical parameters match the original specification. No circuit modifications are required.

Q: Are there differences in the input LED characteristics between these parts?

A: The forward voltage (Vf) of the HCPL-3180-000E is 1.5V compared to 1.35V for the IX3180G, and the maximum DC forward current (If) is 25mA versus 20mA. These differences are within normal component variation and do not affect circuit compatibility when proper input current-limiting resistors are used.

Q: What is the significance of the product status difference?

A: The IX3180G is obsolete, meaning IXYS no longer manufactures or supports this part. The HCPL-3180-000E is active, ensuring long-term availability and manufacturer technical support. This is the primary reason for substitution.

Q: Are the certifications compatible?

A: Yes. The HCPL-3180-000E carries both CSA and UR approvals, which include the UR certification of the original IX3180G. The expanded certification scope of the substitute provides additional regulatory flexibility.

Q: Is the packaging difference significant?

A: The IX3180G was supplied in standard packaging, while the HCPL-3180-000E is supplied in tube packaging. Both are standard through-hole component formats. Tube packaging is compatible with standard component handling, placement, and storage procedures.
