HCPL-2602 Equivalent & Substitute Parts

Part Overview

The HCPL-2602 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 housed in an 8-DIP through-hole package. The part is currently in active production status with 25,300 units available in inventory.

Substitute parts become necessary when the primary part experiences supply constraints, when design requirements shift toward improved compliance standards, or when alternative manufacturers' components meet the electrical and mechanical specifications of the application.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCPL-2602 are evaluated based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Package / Case: 8-DIP (0.300", 7.62mm) — ensures mechanical fit and pinout compatibility
• Mounting Type: Through Hole — maintains assembly process compatibility
• Voltage - Supply: 4.5V ~ 5.5V — ensures power supply compatibility
• Operating Temperature: -40°C ~ 85°C — defines operational environment compatibility
• Number of Channels: 1 — maintains single-channel isolation architecture
• Current - Output / Channel: 50mA — ensures load-driving capability

Secondary Compatibility Criteria:

• Voltage - Isolation: Minimum 3750Vrms — maintains isolation performance threshold
• Propagation Delay tpLH / tpHL (Max): 75ns, 75ns — preserves timing characteristics
• Input Type: AC, DC capability — supports signal input flexibility

The HCPL-2602-000E is a direct manufacturer variant with identical electrical specifications and improved RoHS3 compliance. The HCPL2611 is a manufacturer-recommended alternative from onsemi that shares the 8-DIP package, through-hole mounting, and core supply voltage specifications, though with different isolation voltage and input/output characteristics.

Parameter Comparison

Engineering Selection Recommendations

HCPL-2602-000E: This variant is the preferred direct substitute when RoHS3 compliance is required. It maintains identical electrical specifications, isolation voltage, propagation delay, and supply voltage characteristics as the HCPL-2602. The only distinction is improved environmental compliance status. Current inventory of 3,350 units supports production requirements.

HCPL2611: This onsemi component is a manufacturer-recommended alternative suitable only for applications where the following parameter differences are acceptable: reduced isolation voltage (2500Vrms versus 3750Vrms), DC-only input (versus AC/DC capability), open collector output topology, and higher common mode transient immunity (10kV/µs versus 1kV/µs). The part is currently in obsolete status, which may impact long-term availability. This substitute is appropriate for new designs where the lower isolation voltage meets application requirements and where the open collector output is compatible with the circuit topology.

Frequently Asked Questions (FAQ)

Q: Can HCPL-2602-000E be used as a direct replacement for HCPL-2602?

A: Yes. The HCPL-2602-000E is a direct manufacturer variant with identical electrical specifications, isolation voltage (3750Vrms), propagation delay (75ns), supply voltage (4.5V ~ 5.5V), and 8-DIP package. The primary difference is ROHS3 compliance status.

Q: What are the key differences between HCPL-2602 and HCPL2611?

A: The HCPL2611 differs in three critical areas: isolation voltage is reduced to 2500Vrms (versus 3750Vrms), input type is DC-only (versus AC/DC), and output topology is open collector (versus line receiver). The HCPL2611 offers higher common mode transient immunity at 10kV/µs. These differences require circuit-level evaluation before substitution.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 8-DIP (0.300", 7.62mm) through-hole package, ensuring mechanical and pinout compatibility on existing PCB designs.

Q: What is the inventory status for each part?

A: HCPL-2602 has 25,300 units in stock, HCPL-2602-000E has 3,350 units, and HCPL2611 has 2,092 units available.

Q: Is HCPL2611 suitable for new designs?

A: HCPL2611 is currently in obsolete status. While it meets the 8-DIP package and supply voltage requirements, its obsolete classification may limit long-term availability and support. Evaluation should prioritize HCPL-2602 or HCPL-2602-000E for new designs.

Q: What supply voltage range do all three parts support?

A: All three parts operate with a supply voltage range of 4.5V ~ 5.5V, ensuring compatibility with standard 5V logic supply systems.
