Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-M454 is determined by the following critical parameters:

• Isolation Voltage: All substitutes maintain 3750Vrms isolation voltage
• Output Type: All substitutes feature transistor output configuration
• Number of Channels: All substitutes provide single-channel isolation
• Input Type: All substitutes accept DC input
• Current Transfer Ratio Range: Substitutes vary between 15% to 60% @ 16mA; the HCPL-M454 specifies 25% to 60%
• Output Current: All substitutes deliver 8mA per channel
• Maximum Output Voltage: Substitutes range from 20V to 35V; the HCPL-M454 specifies 20V maximum
• Operating Temperature: Substitutes range from -40°C to 110°C; the HCPL-M454 operates -55°C to 100°C
• Switching Speed: Turn-on/turn-off times vary from 200ns to 1µs
• Package Compatibility: All substitutes use 6-SOIC or equivalent 5-lead surface mount packages

Substitutes are grouped by manufacturer and packaging format while maintaining core electrical specifications for 3750Vrms single-channel transistor output optoisolators.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalent (Identical Electrical Performance)

HCPL-M454-000E is the direct equivalent manufactured by Broadcom Limited with identical electrical specifications. This part differs only in RoHS compliance status (ROHS3 Compliant versus non-compliant) and packaging format (Tube versus standard). Selection of HCPL-M454-000E is appropriate when RoHS3 compliance is required or when tube packaging is preferred for automated assembly.

High Current Transfer Ratio Alternatives

VOM452T and VOM453T from Vishay Semiconductor Opto Division maintain the highest current transfer ratio range (20% to 50% @ 16mA) among substitutes, with faster switching characteristics (200ns turn-on). These parts support higher maximum output voltage (25V) and are ROHS3 compliant. Both parts operate across the full -55°C to 100°C temperature range matching the original HCPL-M454.

Extended Temperature Range Option

TLP2309(E) and TLP2309(TPL,E) from Toshiba Semiconductor extend the upper operating temperature to 110°C while maintaining 3750Vrms isolation. These parts feature lower minimum operating temperature (-40°C) and are ROHS3 compliant. Switching speed is slower (1µs turn-on/turn-off) compared to the HCPL-M454.

Higher Output Voltage Capability

PS8101-F3-AX from Renesas Electronics Corporation provides maximum output voltage of 35V, exceeding the HCPL-M454 specification of 20V. This part maintains -55°C to 100°C operating range and ROHS3 compliance. Current transfer ratio is lower (15% to 35% @ 16mA) and switching speed is slower (500ns/600ns).

Availability and Compliance Considerations

All substitute parts carry ROHS3 compliance status. Inventory levels vary significantly: PC457L0NIP0F (71,866 units), TLP2309(TPL,E) (22,621 units), VOM452T (18,600 units), and HCPL-M454-000E (6,086 units) offer highest availability. Selection should prioritize application-specific electrical requirements over inventory levels.

Frequently Asked Questions (FAQ)

Q: Can HCPL-M454-000E be used as a direct replacement for HCPL-M454?

A: Yes. HCPL-M454-000E is electrically identical to HCPL-M454 with matching isolation voltage (3750Vrms), current transfer ratio (25% to 60% @ 16mA), output voltage (20V maximum), and operating temperature range (-55°C to 100°C). The primary difference is ROHS3 compliance status and packaging format (Tube). Pin configuration and package footprint are identical.

Q: What are the key differences between Vishay VOM452T/VOM453T and the HCPL-M454?

A: VOM452T and VOM453T maintain identical isolation voltage and operating temperature range but feature higher current transfer ratio (20% to 50% versus 25% to 60%), higher maximum output voltage (25V versus 20V), and faster switching speed (200ns turn-on versus 200ns, but 500ns turn-off versus 300ns). All three parts are ROHS3 compliant and use compatible 6-SOIC 5-lead packages.

Q: Why does PS8101-F3-AX have lower current transfer ratio than HCPL-M454?

A: PS8101-F3-AX from Renesas specifies 15% to 35% current transfer ratio @ 16mA compared to HCPL-M454's 25% to 60%. This lower CTR range reflects different LED and phototransistor design characteristics in the Renesas NEPOC series. PS8101-F3-AX compensates with higher maximum output voltage (35V) and extended operating temperature capability to 100°C.

Q: Are all substitute parts available in the same 6-SOIC package?

A: All substitute parts use 6-SOIC or equivalent 5-lead surface mount packages with compatible footprints. Package dimensions vary slightly: HCPL-M454 and PC457L0NIP0F use 0.173" width, while TLP2309 variants use 0.179" width. These minor dimensional differences do not affect PCB layout compatibility for standard 6-SOIC footprints.

Q: Which substitute part offers the best switching performance?

A: VOM452T and VOM453T from Vishay offer the fastest switching characteristics with 200ns turn-on time matching HCPL-M454, combined with 500ns turn-off time. HCPL-M454 specifies 200ns turn-on and 300ns turn-off. TLP2309 variants are slower at 1µs for both turn-on and turn-off. PS8101-F3-AX is slowest at 500ns turn-on and 600ns turn-off.

Q: What is the temperature operating range difference between substitutes?

A: HCPL-M454 and most substitutes operate -55°C to 100°C. TLP2309(E) and TLP2309(TPL,E) extend upper temperature to 110°C but limit lower temperature to -40°C. PC457L0NIP0F limits upper temperature to 85°C. Application requirements for extreme temperature operation should drive substitute selection.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed carry ROHS3 compliance status. The original HCPL-M454 is RoHS non-compliant. HCPL-M454-000E provides the same electrical performance with ROHS3 compliance for applications requiring RoHS certification.

Q: Can TLP2309 variants be used in high-speed switching applications?

A: TLP2309(E) and TLP2309(TPL,E) feature slower switching speed (1µs turn-on and turn-off) compared to HCPL-M454 (200ns/300ns). These parts are suitable for applications with switching frequencies below 500 kHz. For higher-speed applications, VOM452T, VOM453T, or HCPL-M454-000E are preferred.
