HCPL2601W Equivalent & Substitute Parts

Part Overview

The HCPL2601W is a logic output optoisolator manufactured by onsemi, designed for high-speed digital isolation applications requiring 2500Vrms isolation voltage. This component features open collector output topology with 10Mbps data rate capability and 5kV/µs common mode transient immunity, making it suitable for industrial control, power management, and communication interface circuits.

The HCPL2601W is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance and reproduction.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL2601W is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 2500Vrms (mandatory match)
• Number of Channels: 1 channel (mandatory match)
• Output Type: Open Collector (mandatory match)
• Input Type: DC (mandatory match)
• Common Mode Transient Immunity: 5kV/µs minimum (mandatory match)
• Data Rate: 10Mbps (mandatory match)
• Current - Output / Channel: 50 mA (mandatory match)
• Voltage - Supply: 4.5V ~ 5.5V (mandatory match)
• Operating Temperature Range: -40°C ~ 85°C (mandatory match)
• Mounting Type: Through Hole (mandatory match)
• Package Type: 8-DIP (mandatory match)

The HCPL2601 qualifies as a direct substitute for the HCPL2601W, meeting all electrical and mechanical parameters without deviation.

Parameter Comparison

Engineering Selection Recommendations

The HCPL2601 is a direct electrical equivalent to the HCPL2601W. Both components are classified as obsolete products from onsemi and share identical electrical specifications, isolation ratings, and functional characteristics.

The primary difference between these parts is the package body dimension: the HCPL2601W uses 0.400" (10.16mm) DIP spacing, while the HCPL2601 uses 0.300" (7.62mm) DIP spacing. This dimensional variation may affect PCB layout compatibility and socket fitment. Verify physical package dimensions against your circuit board design before substitution.

Both parts maintain REACH Unaffected status and EAR99 export classification. The HCPL2601 carries RoHS3 compliance certification, whereas the HCPL2601W does not specify RoHS status. For applications requiring RoHS compliance documentation, the HCPL2601 is the preferred selection.

Frequently Asked Questions (FAQ)

Q: Can HCPL2601 directly replace HCPL2601W in existing designs?

A: Electrical substitution is valid. All functional parameters, isolation voltage, output characteristics, and timing specifications are identical. Physical package dimensions differ (0.300" vs 0.400" DIP spacing), requiring verification of PCB socket and layout compatibility.

Q: What are the critical parameters that must match for substitution?

A: Isolation voltage (2500Vrms), number of channels (1), output type (open collector), input type (DC), common mode transient immunity (5kV/µs), data rate (10Mbps), output current (50 mA), supply voltage range (4.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and package type (8-DIP) must all match exactly.

Q: Why is the HCPL2601W obsolete?

A: Product obsolescence is determined by the manufacturer. Both HCPL2601W and HCPL2601 are classified as obsolete by onsemi. Availability may be limited to existing inventory from authorized distributors.

Q: Does package dimension difference affect electrical performance?

A: No. The 0.300" versus 0.400" DIP spacing difference is a physical dimension variation only. Electrical performance, timing characteristics, and isolation specifications remain identical. Physical fitment in existing PCB sockets or breadboards may be affected.

Q: What compliance certifications apply to these parts?

A: Both parts maintain REACH Unaffected status and EAR99 export classification. The HCPL2601 specifies RoHS3 compliance; the HCPL2601W does not provide RoHS certification status.
