HCPL4502V Equivalent & Substitute Parts

Part Overview

The HCPL4502V is an optoisolator transistor with base output manufactured by onsemi, providing 2500Vrms isolation in a single-channel 8-DIP package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The HCPL4502V features DC input with transistor output, suitable for applications requiring galvanic isolation in low-current switching circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL4502V is determined by the following critical parameters:

• Package Compatibility: All substitutes maintain the 8-DIP (0.300", 7.62mm) through-hole form factor, ensuring mechanical and electrical pin compatibility.
• Output Configuration: All substitutes provide transistor output with base connection, matching the HCPL4502V output topology.
• Single Channel: All substitutes are single-channel optoisolators, maintaining functional equivalence.
• DC Input: All substitutes accept DC input, preserving signal type compatibility.
• Isolation Voltage: Substitute parts provide equal or higher isolation voltage ratings (3750Vrms, 5000Vrms), ensuring superior or equivalent isolation performance.
• Output Voltage and Current: All substitutes support 20V maximum output voltage and 8mA output current per channel, matching the HCPL4502V specifications.
• Operating Temperature Range: Substitute parts operate within -40°C ~ 85°C, which covers the standard industrial temperature range; applications requiring the extended -55°C ~ 100°C range of the HCPL4502V must be evaluated separately.
• Product Status: All substitute parts are classified as Active, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts (HCPL-4562, HCPL-4562-000E, HCPL-4562-020E, HCPL-4562-060E) are classified as Active products manufactured by Broadcom Limited and are ROHS3 Compliant, providing regulatory compliance and long-term availability assurance compared to the obsolete HCPL4502V.

HCPL-4562 and HCPL-4562-060E provide 3750Vrms isolation, exceeding the HCPL4502V specification by 1250Vrms while maintaining identical output voltage and current ratings. These variants are suitable for applications where the original 2500Vrms isolation is sufficient.

HCPL-4562-020E provides 5000Vrms isolation, the highest rating among available substitutes, offering maximum isolation margin for demanding applications requiring enhanced galvanic separation.

HCPL-4562-000E is supplied in Tube packaging, while HCPL-4562-020E and HCPL-4562-060E are also supplied in Tube packaging. The base HCPL-4562 variant packaging is not specified in the provided data.

All substitutes operate within the -40°C ~ 85°C temperature range. Applications requiring the extended -55°C ~ 100°C operating range of the HCPL4502V require thermal analysis to confirm suitability within the narrower substitute temperature specification.

Frequently Asked Questions (FAQ)

Q: Can HCPL-4562 variants directly replace HCPL4502V in existing designs?

A: Yes, all four substitute parts maintain identical 8-DIP package geometry, pin configuration, DC input type, and transistor output topology. Direct pin-for-pin substitution is mechanically and electrically compatible. However, the operating temperature range differs: substitutes operate at -40°C ~ 85°C versus the HCPL4502V range of -55°C ~ 100°C. Designs operating outside the -40°C ~ 85°C window require thermal validation.

Q: What is the difference between HCPL-4562, HCPL-4562-000E, HCPL-4562-020E, and HCPL-4562-060E?

A: The primary difference is isolation voltage rating. HCPL-4562 and HCPL-4562-060E provide 3750Vrms isolation. HCPL-4562-020E provides 5000Vrms isolation. All other electrical parameters remain identical. Packaging differs: HCPL-4562-000E, HCPL-4562-020E, and HCPL-4562-060E are supplied in Tube packaging.

Q: Why do substitute parts have lower maximum forward current (12mA vs 25mA)?

A: The HCPL-4562 series specifies 12mA maximum DC forward current compared to the HCPL4502V specification of 25mA. This parameter defines the maximum input LED current. Applications designed for the HCPL4502V input current range must be evaluated to confirm compatibility with the lower HCPL-4562 specification.

Q: Are all substitute parts RoHS compliant?

A: Yes, all four substitute parts are ROHS3 Compliant. The HCPL4502V RoHS status is not specified in the provided data.

Q: Which substitute part should be selected for maximum isolation voltage?

A: HCPL-4562-020E provides the highest isolation voltage rating at 5000Vrms, suitable for applications requiring maximum galvanic separation margin.

Q: Is the 8-DIP package identical across all parts?

A: Yes, all parts use the 8-DIP (0.300", 7.62mm) through-hole package with identical pin spacing and mechanical dimensions, ensuring direct board-level compatibility.
