HCPL-4562 Optoisolator Equivalent & Substitute Parts

Part Overview

The HCPL-4562 is an optoisolator transistor with base output manufactured by Broadcom Limited, designed for high-voltage isolation applications requiring 3750Vrms isolation rating. This active product operates as a DC input optoisolator with transistor output configuration in an 8-DIP through-hole package. Substitute parts are necessary when addressing supply constraints, extended temperature range requirements, higher isolation voltage specifications, or alternative manufacturer availability while maintaining functional compatibility within system design parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-4562 is determined by the following critical parameters:

Core Compatibility Requirements:

• Single channel configuration (1 Channel)
• DC input type
• Transistor with base output configuration
• Through-hole mounting type
• 8-DIP package form factor
• ROHS3 compliance and MSL 1 rating

Allowable Parameter Variations:

• Isolation voltage rating of 3750Vrms or higher (5000Vrms, 5300Vrms acceptable)
• Output voltage maximum of 20V or higher
• Output current of 8mA or higher
• Forward voltage (Vf) within typical operating range (1.3V to 1.7V)
• Maximum forward current (If) of 12mA or higher
• Operating temperature range equal to or broader than -40°C ~ 85°C
• Active product status with current manufacturer support

Non-Substitutable Parameters:

• Channel count must remain 1
• Input and output types must match exactly
• Package type must be 8-DIP through-hole
• Mounting configuration must be through-hole

Parameter Comparison

Engineering Selection Recommendations

Direct Broadcom Equivalent: HCPL-4562-000E is the direct equivalent variant, differing only in packaging format (Tube). This part maintains identical electrical specifications and is suitable for direct substitution when tube packaging is acceptable.

Higher Isolation Voltage Alternatives: Parts with 5000Vrms or 5300Vrms isolation ratings (6N136-X001, PS8501 series, SFH6136-X001) provide enhanced isolation margin beyond the 3750Vrms requirement. These are suitable substitutes when system design permits higher isolation voltage specifications. All maintain the required 8mA output current and transistor with base configuration.

Extended Temperature Range Consideration: Substitute parts rated for -55°C ~ 100°C operating temperature provide broader thermal coverage compared to the HCPL-4562 specification of -40°C ~ 85°C. Selection depends on application thermal requirements.

Package Footprint Compatibility: PS8501L1-AX and PS8501L1-V-AX use 8-DIP (0.400", 10.16mm) package spacing, differing from the standard 0.300" (7.62mm) spacing. These require PCB layout verification before substitution. All other alternatives maintain 0.300" spacing compatibility.

Compliance Status: All substitute parts maintain ROHS3 compliance and MSL 1 rating. PS8501-AX carries REACH Affected status, while all other alternatives are REACH Unaffected. Regulatory requirements should guide selection in restricted applications.

Frequently Asked Questions (FAQ)

Q: Can PS8501L1-AX be used as a direct drop-in replacement? A: PS8501L1-AX is electrically compatible but uses 8-DIP (0.400", 10.16mm) package spacing versus the HCPL-4562 standard 0.300" spacing. PCB layout modification is required; it is not a direct drop-in replacement without board redesign.

Q: What is the primary difference between 6N136-X001 and PS8501-AX? A: Both provide 5000Vrms or higher isolation. 6N136-X001 (Vishay) offers 5300Vrms isolation with 19% minimum current transfer ratio at 16mA and 200ns switching time. PS8501-AX (Renesas) provides 5000Vrms isolation with 15% minimum current transfer ratio and 220ns/350ns turn-on/turn-off times. Selection depends on switching speed and current transfer ratio requirements.

Q: Are all substitute parts suitable for the same temperature range? A: No. The HCPL-4562 operates -40°C ~ 85°C. All listed substitutes operate -55°C ~ 100°C, providing extended range. If the application requires only -40°C ~ 85°C operation, both original and substitute parts are suitable. If extended temperature operation is needed, substitutes are required.

Q: What does REACH Affected status mean for PS8501-AX? A: REACH Affected indicates the part may contain substances of concern under EU REACH regulations. PS8501-AX carries this designation while other substitutes are REACH Unaffected. Selection should consider regulatory compliance requirements for the target market.

Q: Can I substitute based on isolation voltage alone? A: No. Isolation voltage is one parameter. Substitution requires matching channel count (1), input type (DC), output type (transistor with base), mounting type (through-hole), and package form (8-DIP). All these parameters must align for functional compatibility.

Q: What is the significance of Current Transfer Ratio specifications? A: Current Transfer Ratio defines the relationship between input and output current. The HCPL-4562 does not specify this parameter. Substitutes with specified ratios (6N136-X001 at 19%, PS8501 series at 15%) provide measurable performance data. Higher ratios indicate more efficient signal transfer at given input currents.

Q: Is HCPL-4562-000E the only direct Broadcom substitute? A: HCPL-4562-000E is the variant listed in the substitute parts database. It maintains identical electrical specifications to HCPL-4562, differing only in packaging format (Tube versus standard packaging).
