HCPL-2602-500E Equivalent & Substitute Parts

Part Overview

The HCPL-2602-500E 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 product maintains Active status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts become necessary when the HCPL-2602-500E reaches end-of-life status, when inventory constraints occur, or when design requirements permit operation within the electrical and mechanical parameters of alternative optoisolator line receivers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-2602-500E is determined by the following critical parameters:

Isolation Voltage Rating: The substitute part must maintain isolation capability at or above 2500Vrms. The HCPL-2602-500E operates at 3750Vrms; substitutes operating at lower isolation ratings (such as 2500Vrms) are acceptable when circuit design permits reduced isolation margins.

Channel Configuration: Single-channel operation is required. Substitute parts must provide exactly one isolated channel.

Input/Output Characteristics: The HCPL-2602-500E accepts both AC and DC inputs with line receiver output. Substitute parts must support compatible input types and output configurations.

Electrical Performance: Output current capability (50mA), propagation delay (75ns maximum), and supply voltage range (4.5V ~ 5.5V) establish the performance envelope for substitution.

Package Compatibility: The 8-SMD Gull Wing surface mount package defines the physical footprint. Substitute parts must use identical or compatible package geometry to ensure PCB layout compatibility.

Compliance & Status: RoHS3 compliance and active product status are preferred but not absolute barriers to substitution when legacy designs require specific part characteristics.

Engineering Selection Recommendations

The HCPL2601SD from onsemi presents a viable substitute when the following conditions are met:

Isolation Voltage Requirement: Designs requiring 3750Vrms isolation must not use HCPL2601SD, which provides only 2500Vrms isolation. Designs with maximum isolation requirements of 2500Vrms or lower may proceed with substitution.

Input Signal Type: The HCPL-2602-500E accepts both AC and DC inputs. The HCPL2601SD accepts DC input only. Circuits supplying AC input signals cannot use this substitute without signal conditioning.

Output Configuration: The HCPL-2602-500E provides line receiver output. The HCPL2601SD provides open collector output. Circuit designs must accommodate open collector logic levels and pull-up resistor requirements.

Compliance Status: Both parts maintain RoHS3 compliance. The HCPL2601SD carries Obsolete product status, indicating limited future availability. New designs should prioritize the Active HCPL-2602-500E or identify alternative Active substitutes.

Performance Equivalence: Both parts share identical propagation delay (75ns maximum), output current (50mA), and supply voltage range (4.5V ~ 5.5V). The HCPL2601SD provides superior common mode transient immunity (5kV/µs versus 1kV/µs), beneficial for high-speed switching environments.

Frequently Asked Questions (FAQ)

Q: Can HCPL2601SD replace HCPL-2602-500E in all applications?

A: No. Substitution is limited to applications where isolation voltage requirements do not exceed 2500Vrms, input signals are DC only, and open collector output is compatible with the circuit design.

Q: What is the primary difference between these optoisolators?

A: The HCPL-2602-500E is a line receiver with 3750Vrms isolation accepting AC/DC inputs. The HCPL2601SD is a logic output optoisolator with 2500Vrms isolation accepting DC input only and providing open collector output.

Q: Are both parts pin-compatible?

A: Both parts use 8-SMD Gull Wing packages with identical physical footprints. Pin-level compatibility depends on circuit design; the different output types (line receiver versus open collector) require verification of signal interface requirements.

Q: Why is HCPL2601SD marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. Existing inventory may be available through authorized distributors, but long-term availability is not guaranteed.

Q: What certifications apply to both parts?

A: Both parts maintain RoHS3 compliance, CSA/UR approval (HCPL-2602-500E), and REACH Unaffected status. Both carry EAR99 export classification.

Q: Can I use HCPL2601SD if my circuit only requires 2500Vrms isolation?

A: Yes, provided the circuit uses DC input signals and the open collector output configuration is compatible with downstream logic requirements.
