HCPL-T250#060 Equivalent & Substitute Parts

Part Overview

The HCPL-T250#060 is a 1.5A gate driver optical coupler manufactured by Broadcom Limited, providing 3750Vrms isolation for single-channel gate drive applications. This component is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines. Substitute parts must maintain compatibility with the 8-DIP through-hole package and support the required isolation voltage and output current specifications for gate driver applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-T250#060 is determined by the following critical parameters:

• Package Compatibility: All substitutes must use 8-DIP through-hole mounting in the 0.300" (7.62mm) pitch configuration
• Isolation Voltage: Minimum 3750Vrms isolation required; higher isolation ratings are acceptable
• Output Current: Peak output current of 1.5A minimum; higher ratings provide design margin
• Output Supply Voltage Range: Must support 15V ~ 30V operation
• Single Channel Configuration: All substitutes maintain single-channel gate driver topology
• Optical Coupling Technology: All alternatives use optical isolation technology

Substitute parts are grouped into two categories:

Direct Broadcom Equivalent: HCPL-T250-060E maintains identical electrical specifications with improved product status (Active vs. Discontinued) and enhanced RoHS compliance.

Cross-Manufacturer Alternatives: FOD3120, FOD3120V, FOD3180, and LTV-3150 series provide higher isolation voltage (5000Vrms), improved common mode transient immunity, and active product status. These parts exceed the minimum isolation requirement and offer enhanced performance margins.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: HCPL-T250-060E

The HCPL-T250-060E is the direct Broadcom equivalent with identical electrical specifications. This part maintains the same isolation voltage (3750Vrms), propagation delay (500ns), peak output current (1.5A), and output supply voltage range (15V ~ 30V). The primary advantages are active product status and ROHS3 compliance, eliminating obsolescence risk and meeting modern environmental standards.

Secondary Recommendations: FOD3120 / FOD3120V

The FOD3120 and FOD3120V from onsemi provide enhanced performance with 5000Vrms isolation and 35kV/µs common mode transient immunity. These parts exceed the minimum isolation requirement and offer faster propagation delay (400ns). Peak output current of 3A provides significant design margin over the 1.5A requirement. Both parts are ROHS3 compliant and actively manufactured. The FOD3120V includes IEC approval in addition to UL certification.

Tertiary Recommendation: FOD3180

The FOD3180 offers 5000Vrms isolation with the fastest propagation delay (200ns) among all substitutes. Peak output current of 2.5A exceeds the 1.5A requirement. The output supply voltage range (10V ~ 20V) is narrower than the original part; applications requiring operation above 20V are not suitable for this substitute. ROHS3 compliant with cUL and UL approvals.

Alternative Recommendation: LTV-3150 / LTV-3150M

The LTV-3150 series from Lite-On provides 5000Vrms isolation with 15kV/µs common mode transient immunity. Peak output current of 1A is below the original 1.5A specification; this part is suitable only for applications with reduced output current requirements. The LTV-3150M uses a 0.400" (10.16mm) DIP pitch, which is incompatible with standard 0.300" pitch PCB layouts. Both variants are ROHS3 compliant with extended operating temperature range (-40°C ~ 105°C).

Frequently Asked Questions (FAQ)

Q: Can I use FOD3180 as a direct replacement for HCPL-T250#060?

A: FOD3180 is mechanically and functionally compatible with the same 8-DIP 0.300" pitch package. However, the output supply voltage range (10V ~ 20V) is narrower than the original (15V ~ 30V). If your application operates above 20V, FOD3180 is not suitable. For applications within the 10V ~ 20V range, FOD3180 provides superior performance with faster propagation delay (200ns vs. 500ns).

Q: What is the difference between FOD3120 and FOD3120V?

A: Both parts are electrically identical with 5000Vrms isolation, 3A peak output current, and 400ns propagation delay. The primary difference is certification: FOD3120 carries UL approval, while FOD3120V includes both IEC and UL approvals. For applications requiring IEC compliance, FOD3120V is the appropriate selection.

Q: Why does LTV-3150M have a different package pitch (0.400" vs. 0.300")?

A: The LTV-3150M uses a 0.400" (10.16mm) DIP pitch, which is physically incompatible with PCB layouts designed for the standard 0.300" (7.62mm) pitch used by HCPL-T250#060 and other substitutes. LTV-3150M requires custom PCB footprints and is not recommended as a drop-in replacement. Use LTV-3150 (0.300" pitch) if Lite-On sourcing is required.

Q: Is HCPL-T250-060E a true drop-in replacement?

A: Yes. HCPL-T250-060E is the direct Broadcom equivalent with identical electrical specifications, package, and pinout. It is a true drop-in replacement with no circuit modifications required. The primary advantages are active product status and ROHS3 compliance.

Q: Which substitute offers the best performance improvement?

A: FOD3180 provides the fastest propagation delay (200ns vs. 500ns original), enabling higher switching frequencies. FOD3120 and FOD3120V offer the highest common mode transient immunity (35kV/µs vs. 5kV/µs original) and peak output current (3A vs. 1.5A), providing the greatest design margin for noise immunity and output drive capability.

Q: Are all substitutes RoHS compliant?

A: HCPL-T250-060E, FOD3120, FOD3120V, FOD3180, LTV-3150, and LTV-3150M are all ROHS3 compliant. The original HCPL-T250#060 is RoHS non-compliant. If RoHS compliance is required, any of the listed substitutes are acceptable.

Q: Can I use LTV-3150 if my application requires only 1A peak output current?

A: Yes. LTV-3150 provides 1A peak output current, which meets applications with this requirement. However, the 800mA continuous output (High/Low) is lower than the original 500mA specification. Verify that your gate drive circuit can operate with reduced continuous output current before selecting this part.
