HCPL2611SV Equivalent & Substitute Parts

Part Overview

The HCPL2611SV 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 HCPL2611SV is classified as obsolete. Identifying functionally equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support long-term product availability for new designs and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL2611SV is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating: 2500Vrms
• Single channel configuration with open collector output
• Data rate: 10Mbps minimum
• Common mode transient immunity: 10kV/µs minimum
• Output current capability: 50 mA per channel
• Propagation delay specifications: 75ns maximum (both tpLH and tpHL)
• Supply voltage range: 4.5V to 5.5V
• Operating temperature range: -40°C to 85°C
• Package type: 8-SMD, Gull Wing surface mount
• RoHS3 compliance requirement

The HCPL2611SVM qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The HCPL2611SVM is the recommended substitute for the obsolete HCPL2611SV. Both parts are manufactured by onsemi and maintain identical electrical and mechanical specifications across all critical parameters. The HCPL2611SVM carries active product status, ensuring ongoing availability and supply chain support.

Both parts satisfy ROHS3 compliance, REACH unaffected status, and EAR99 export classification requirements. The HCPL2611SVM is supplied in tube packaging, whereas the HCPL2611SV packaging specification was not provided. Both components feature MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage or handling.

For new designs and legacy system replacements, the HCPL2611SVM provides equivalent functional performance with the advantage of active manufacturer support and confirmed long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the HCPL2611SVM directly replace the HCPL2611SV in existing circuit designs?

A: Yes. The HCPL2611SVM is electrically and mechanically equivalent to the HCPL2611SV. Both parts share identical isolation voltage (2500Vrms), output type (open collector), data rate (10Mbps), propagation delay specifications (75ns maximum), supply voltage range, operating temperature range, and 8-SMD Gull Wing package configuration. No circuit modifications are required.

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

A: The HCPL2611SV is classified as obsolete, while the HCPL2611SVM maintains active product status. The HCPL2611SVM is the current production equivalent and is recommended for all new designs and replacement applications.

Q: Are there any supply voltage differences between these parts?

A: The HCPL2611SV specifies a supply voltage range of 4.5V to 5.5V. The HCPL2611SVM specifies 5.5V. Both parts operate within standard 5V logic supply environments. Designs operating at the lower end of the 4.5V range should verify compatibility with the HCPL2611SVM specification.

Q: Do both parts require identical PCB layout and handling procedures?

A: Yes. Both parts use the same 8-SMD Gull Wing package and share MSL Level 1 (Unlimited) moisture sensitivity rating. Identical PCB layout, soldering procedures, and component handling practices apply to both parts.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both share identical HTSUS classification (8541.49.8000). Compliance requirements are equivalent.
