Substitute Part Grouping Explanation

Substitution for the HCPL4502W is determined by the following critical parameters:

• Output Type: Transistor with Base (required for pin-compatible replacement)
• Number of Channels: Single channel
• Mounting Type: Through Hole
• Package Style: 8-DIP configuration
• Input Type: DC
• Voltage - Output (Max): 20V
• Current - Output / Channel: 8mA
• Isolation Voltage: Minimum 2500Vrms (equal or higher acceptable)
• Operating Temperature Range: Must support application requirements
• Product Status: Active status preferred for long-term availability

The HCPL-4562 series from Broadcom Limited meets these substitution criteria. All variants (HCPL-4562, HCPL-4562-000E, HCPL-4562-020E, HCPL-4562-060E) maintain identical output characteristics, package footprint compatibility, and DC input/transistor output configuration. Isolation voltage ratings range from 3750Vrms to 5000Vrms, exceeding the HCPL4502W requirement of 2500Vrms.

Parameter Comparison

Engineering Selection Recommendations

All HCPL-4562 variants are active products with ROHS3 compliance, providing superior long-term availability compared to the obsolete HCPL4502W. Selection among the four substitute options depends on isolation voltage requirements:

HCPL-4562 and HCPL-4562-000E / HCPL-4562-060E: Provide 3750Vrms isolation, exceeding the HCPL4502W baseline of 2500Vrms. These variants are suitable for applications where the original isolation specification is met with margin.

HCPL-4562-020E: Provides 5000Vrms isolation for applications requiring maximum isolation voltage capability.

Packaging Consideration: HCPL-4562 series components use 8-DIP (0.300", 7.62mm) packages, which are mechanically compatible with standard 8-DIP footprints but differ in body width from the HCPL4502W (0.400", 10.16mm). PCB layout verification is required to confirm footprint accommodation.

Operating Temperature: HCPL-4562 series operates from -40°C to 85°C, compared to HCPL4502W range of -55°C to 100°C. Applications requiring extended temperature operation below -40°C or above 85°C require design review.

Input Current: HCPL-4562 series maximum forward current is 12mA versus HCPL4502W at 25mA. Input circuit design must accommodate this reduced specification.

Frequently Asked Questions (FAQ)

Q: Are HCPL-4562 variants pin-compatible with HCPL4502W?

A: Yes. All HCPL-4562 variants maintain identical pin configuration and output electrical characteristics (20V maximum output voltage, 8mA output current per channel, transistor with base output). Pin-level compatibility is confirmed.

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

A: HCPL-4562-020E provides 5000Vrms isolation. HCPL-4562, HCPL-4562-000E, and HCPL-4562-060E provide 3750Vrms isolation. The suffix designations indicate packaging and tape/reel configurations. All variants are functionally equivalent for isolation voltage and output characteristics within their respective ratings.

Q: Can HCPL-4562 replace HCPL4502W in all applications?

A: Substitution is valid for applications where operating temperature remains within -40°C to 85°C range and input forward current does not exceed 12mA. Applications requiring -55°C operation or 25mA input current require design modification or alternative component selection.

Q: What is the physical package difference?

A: HCPL4502W uses 8-DIP (0.400", 10.16mm) body width. HCPL-4562 series uses 8-DIP (0.300", 7.62mm) body width. Both are through-hole mounted with identical pin spacing. PCB footprint compatibility must be verified for the narrower HCPL-4562 package.

Q: Are HCPL-4562 variants RoHS compliant?

A: Yes. All HCPL-4562 variants are ROHS3 compliant. HCPL4502W RoHS status is not specified in available documentation.

Q: Which isolation voltage should I select?

A: Select based on application isolation requirements. HCPL-4562-020E (5000Vrms) provides maximum isolation margin. HCPL-4562 / HCPL-4562-000E / HCPL-4562-060E (3750Vrms) exceed HCPL4502W specification (2500Vrms) with adequate margin for most applications.
