HCPL2503V Equivalent & Substitute Parts

Part Overview

The HCPL2503V is an optoisolator transistor with base output manufactured by onsemi, rated for 2500Vrms isolation voltage in an 8-DIP through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The HCPL2503V provides DC input with transistor output including base connection, suitable for applications requiring galvanic isolation with moderate voltage ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCPL2503V are identified based on the following critical parameters that determine functional compatibility:

Mandatory Compatibility Criteria:

• Output Type: Transistor with Base (required for pin-compatible replacement)
• Mounting Type: Through Hole (required for PCB compatibility)
• Package / Case: 8-DIP (0.300", 7.62mm) (required for socket and board layout compatibility)
• Input Type: DC (required for signal interface compatibility)
• Voltage - Output (Max): 20V (required for output stage compatibility)
• Current - Output / Channel: 8mA (required for load drive capability)
• Number of Channels: 1 (required for functional equivalence)

Allowable Parameter Variations:

• Voltage - Isolation: May be equal to or greater than 2500Vrms (higher isolation voltage provides enhanced performance margin)
• Operating Temperature: May be narrower than -55°C ~ 100°C (subset operation is acceptable if application requirements are met)
• Voltage - Forward (Vf) (Typ): Minor variations acceptable within typical operating ranges
• Current - DC Forward (If) (Max): May be lower than 25mA if application input current requirements are satisfied

All substitute parts listed maintain identical mechanical form factor, electrical interface characteristics, and functional output behavior as the HCPL2503V.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are pin-compatible direct replacements for the HCPL2503V based on identical package, output configuration, and electrical interface specifications.

HCPL-4562 Series Selection Criteria:

The HCPL-4562, HCPL-4562-000E, HCPL-4562-020E, and HCPL-4562-060E are active production components manufactured by Broadcom Limited with ROHS3 compliance, addressing the obsolescence of the HCPL2503V. These parts maintain identical mechanical and functional interfaces while providing enhanced isolation voltage ratings.

Isolation Voltage Considerations:

• HCPL-4562 and HCPL-4562-060E: 3750Vrms isolation (50% higher than HCPL2503V)
• HCPL-4562-020E: 5000Vrms isolation (100% higher than HCPL2503V)

Higher isolation voltage ratings provide additional safety margin and are functionally compatible with applications designed for 2500Vrms isolation.

Packaging Variants:

• HCPL-4562: Standard packaging
• HCPL-4562-000E: Tube packaging
• HCPL-4562-020E: Tube packaging
• HCPL-4562-060E: Tube packaging

Packaging selection depends on procurement and assembly requirements; electrical performance is identical across all variants.

Operating Temperature Range: Substitute parts operate within -40°C ~ 85°C, which is narrower than the HCPL2503V range of -55°C ~ 100°C. Applications requiring operation below -40°C or above 85°C must evaluate temperature compatibility independently.

Input Current Consideration: Substitute parts specify maximum DC forward current of 12mA compared to 25mA for the HCPL2503V. Applications must confirm input drive current requirements do not exceed 12mA.

Frequently Asked Questions (FAQ)

Q: Can HCPL-4562 series parts directly replace HCPL2503V without PCB modifications?

A: Yes. All HCPL-4562 variants are pin-compatible direct replacements. The 8-DIP package, pin configuration, and electrical interface are identical. No PCB layout changes are required.

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-4562-020E provides 5000Vrms isolation, while HCPL-4562, HCPL-4562-000E, and HCPL-4562-060E provide 3750Vrms isolation. Packaging format also differs: HCPL-4562 uses standard packaging, while the others use tube packaging. Electrical performance and pin configuration are otherwise identical.

Q: Is the higher isolation voltage of HCPL-4562-020E (5000Vrms) compatible with HCPL2503V (2500Vrms) applications?

A: Yes. Higher isolation voltage is a superset capability. Applications designed for 2500Vrms isolation operate correctly with components rated for 5000Vrms isolation.

Q: What is the impact of the narrower operating temperature range (-40°C ~ 85°C) of substitute parts compared to HCPL2503V (-55°C ~ 100°C)?

A: Applications operating within -40°C ~ 85°C experience no impact. Applications requiring operation below -40°C or above 85°C must evaluate whether substitute parts meet temperature requirements or if alternative components are necessary.

Q: Are HCPL-4562 series parts RoHS compliant?

A: Yes. All HCPL-4562 variants are ROHS3 compliant. The HCPL2503V RoHS status is not specified in available documentation.

Q: What is the significance of the reduced maximum DC forward current (12mA vs. 25mA)?

A: Applications must confirm input drive current requirements. If the application requires input current exceeding 12mA, substitute parts may not be suitable. Most standard applications operate within 12mA input current limits.

Q: Can I use HCPL-4562-000E or HCPL-4562-060E in applications where HCPL-4562 is specified?

A: Yes. All three parts provide identical electrical performance and pin configuration. Selection between them depends on packaging requirements (tube vs. standard) and procurement availability.
