HCPL2611W Equivalent & Substitute Parts

Part Overview

The HCPL2611W 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 10kV/µs common mode transient immunity, making it suitable for industrial control, power management, and communication interface circuits.

The HCPL2611W 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 redesigns.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL2611W is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 2500Vrms (mandatory match)
• Output Configuration: Open Collector topology (mandatory match)
• Number of Channels: 1 channel (mandatory match)
• Common Mode Transient Immunity: 10kV/µs minimum (mandatory match)
• Data Rate: 10Mbps (mandatory match)
• Input Type: DC (mandatory match)
• Supply Voltage Range: 4.5V ~ 5.5V (mandatory match)
• Mounting Type: Through Hole (mandatory match)
• Package Family: 8-DIP (mandatory match)

The HCPL2611 qualifies as a direct substitute for the HCPL2611W. Both parts share identical electrical specifications, isolation ratings, and functional characteristics. The primary difference is packaging format: HCPL2611W is supplied in tape format, while HCPL2611 is supplied in tube packaging. Both maintain the same 8-DIP physical footprint and pinout compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both HCPL2611W and HCPL2611 are classified as obsolete products. Selection between these parts should be based on the following factors:

Packaging Format: HCPL2611W is supplied in tape packaging, suitable for automated assembly processes. HCPL2611 is supplied in tube packaging, suitable for manual assembly or lower-volume applications.

Compliance Status: HCPL2611 carries RoHS3 compliance certification, while HCPL2611W does not specify RoHS status. Both parts maintain REACH Unaffected status and EAR99 export classification.

Physical Dimensions: HCPL2611W features a 0.400" (10.16mm) DIP body width, while HCPL2611 features a 0.300" (7.62mm) DIP body width. Verify PCB footprint compatibility before substitution, as this dimensional difference may affect board layout and socket compatibility.

Inventory Availability: HCPL2611 maintains higher inventory levels (2092 pcs) compared to HCPL2611W (1129 pcs), providing better supply chain availability for new procurements.

Frequently Asked Questions (FAQ)

Q: Can HCPL2611 directly replace HCPL2611W in existing designs?

A: Electrical substitution is valid. Both parts share identical isolation voltage, output configuration, data rate, and timing specifications. However, verify PCB footprint compatibility due to the 0.100" difference in DIP body width (10.16mm vs 7.62mm). Socket or through-hole spacing may require adjustment.

Q: What is the significance of the packaging difference between HCPL2611W and HCPL2611?

A: The "W" suffix indicates tape packaging format, optimized for high-speed automated pick-and-place assembly. The non-suffixed HCPL2611 uses tube packaging, typical for manual handling or lower-volume production. Electrical performance is identical.

Q: Are there compliance differences between these parts?

A: HCPL2611 is certified RoHS3 compliant, while HCPL2611W does not specify RoHS status. Both maintain REACH Unaffected classification. For applications requiring RoHS compliance documentation, HCPL2611 is the appropriate selection.

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

A: Isolation voltage (2500Vrms), output topology (open collector), channel count (1), CMTI rating (10kV/µs), data rate (10Mbps), supply voltage range (4.5V-5.5V), and package family (8-DIP) must remain constant. Any deviation in these parameters disqualifies substitution.

Q: Why is DIP body width important for substitution?

A: DIP body width affects socket compatibility and PCB footprint spacing. The 0.100" dimensional difference between HCPL2611W (10.16mm) and HCPL2611 (7.62mm) may prevent direct socket insertion or require PCB redesign. Measure existing socket or footprint specifications before substitution.
