HCPL-2602-300E Equivalent & Substitute Parts

Part Overview

The HCPL-2602-300E is an optoisolator line receiver manufactured by Broadcom Limited, designed for high-voltage isolation applications requiring 3750Vrms isolation rating. This component features a single channel with AC/DC input capability and is packaged in an 8-DIP Gull Wing surface mount configuration. The part is currently in active production status with 5900 units available in inventory.

Substitute parts become necessary when the HCPL-2602-300E reaches end-of-life status, when supply constraints occur, or when design requirements allow for alternative isolation ratings and performance characteristics within acceptable operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-2602-300E is determined by the following critical parameters:

• Isolation Voltage Rating: The substitute must maintain isolation capability at or above the application requirement. The HCPL2601SD provides 2500Vrms isolation, which is lower than the primary part's 3750Vrms rating.
• Number of Channels: Must be 1 channel to match the original configuration.
• Output Current Capability: Both parts support 50mA output current per channel.
• Supply Voltage Range: Both parts operate within 4.5V ~ 5.5V supply range.
• Operating Temperature Range: Both parts support -40°C ~ 85°C operation.
• Package Configuration: Both parts use 8-SMD Gull Wing surface mount packaging.
• Propagation Delay: Both parts specify 75ns maximum propagation delay for tpLH and tpHL.

The HCPL2601SD is identified as a manufacturer-recommended substitute despite its lower isolation voltage rating of 2500Vrms. This substitution is valid only for applications where the lower isolation rating meets design requirements. The HCPL2601SD is currently marked as obsolete product status.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-2602-300E is the primary component choice for applications requiring 3750Vrms isolation with AC/DC input capability. Both the primary part and substitute are ROHS3 compliant and carry unlimited moisture sensitivity rating, indicating robust handling characteristics.

The HCPL2601SD substitute is currently in obsolete product status, which limits its suitability for new designs or long-term production commitments. Selection of the HCPL2601SD is appropriate only when the application isolation requirement can be satisfied by the 2500Vrms rating and when DC-only input operation is acceptable. The HCPL2601SD provides superior common mode transient immunity at 5kV/µs compared to the primary part's 1kV/µs specification.

Both parts maintain identical propagation delay characteristics and output current capability, ensuring timing-critical applications can transition between these components without circuit redesign. The difference in input type (AC/DC versus DC-only) and output configuration (line receiver versus open collector) represents the primary functional distinction between these parts.

Frequently Asked Questions (FAQ)

Q: Can the HCPL2601SD directly replace the HCPL-2602-300E in all applications?

A: Direct replacement is not universal. The HCPL2601SD has a lower isolation voltage rating (2500Vrms versus 3750Vrms) and accepts DC input only, whereas the HCPL-2602-300E accepts both AC and DC inputs. Substitution is valid only when the application isolation requirement does not exceed 2500Vrms and when AC input capability is not required.

Q: What is the significance of the different output types between these parts?

A: The HCPL-2602-300E is configured as a line receiver, while the HCPL2601SD uses open collector output. These output configurations require different circuit implementations and pull-up resistor configurations. Circuit redesign may be necessary when substituting between these output types.

Q: Why does the HCPL2601SD have higher common mode transient immunity?

A: The HCPL2601SD specifies 5kV/µs CMTI compared to the HCPL-2602-300E's 1kV/µs. This parameter is provided in the component specifications and reflects the respective design characteristics of each part. Higher CMTI indicates greater immunity to rapid voltage changes in the isolation barrier.

Q: Are both parts suitable for new product designs?

A: The HCPL-2602-300E is in active production status and is the appropriate choice for new designs. The HCPL2601SD is marked as obsolete, making it unsuitable for new product development or applications requiring long-term component availability.

Q: Do both parts require the same supply voltage?

A: Yes. Both the HCPL-2602-300E and HCPL2601SD operate within the 4.5V ~ 5.5V supply voltage range and support identical operating temperature ranges of -40°C ~ 85°C.

Q: What packaging considerations apply to these parts?

A: Both parts use 8-SMD Gull Wing surface mount packaging, allowing for identical PCB footprints and assembly processes. No mechanical redesign is required when substituting between these parts from a packaging perspective.
