HCPL-M454-560 Optoisolator Equivalent & Substitute Parts

Part Overview

The HCPL-M454-560 is a 3750Vrms optoisolator with transistor output manufactured by Broadcom Limited. This single-channel device is designed for DC input applications requiring galvanic isolation in 6-SOIC surface mount packaging. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines. Substitute parts must maintain isolation voltage, output type, channel configuration, and mechanical compatibility while meeting modern RoHS compliance requirements.

Toshiba TLP2309(E) / TLP2309(TPL,E): These parts provide 15% minimum CTR with extended operating temperature range (-40°C ~ 110°C). Switching times are significantly slower (1µs maximum) compared to the original. Packaging variants differ (Tube vs. Cut Tape & Digi-Reel). ROHS3 compliance and active status are confirmed.

Frequently Asked Questions (FAQ)

Q: Can HCPL-M454-560E be used as a direct replacement for HCPL-M454-560?

A: Yes. HCPL-M454-560E is the active equivalent from Broadcom Limited with identical electrical specifications (3750Vrms isolation, 25-60% CTR, 200ns/300ns switching times) and the same 6-SOIC package. The primary difference is ROHS3 compliance and Tape & Reel packaging. No circuit modifications are required.

Q: What is the difference between HCPL-M454-560E and HCPL-M454-500E?

A: Both parts are parametric equivalents from Broadcom with identical electrical performance. The suffix difference (-560E vs. -500E) reflects internal product line designation. Both maintain 3750Vrms isolation, 25-60% CTR, and -55°C ~ 100°C operating range. Selection can be based on availability and packaging preference.

Q: Are cross-manufacturer substitutes (Vishay, Everlight, SHARP, Renesas, Toshiba) pin-compatible with HCPL-M454-560?

A: All listed substitutes maintain the 6-SOIC form factor with 5 leads and identical pinout configuration. Physical and electrical pin compatibility is confirmed. However, minor variations in supplier device package designation (5-SO, 5-SOP, 5-MFP) reflect internal packaging standards and do not affect PCB footprint compatibility.

Q: Which substitute part has the best current transfer ratio match?

A: HCPL-M454-560E and HCPL-M454-500E maintain the original 25-60% CTR specification. Vishay VOM452T and VOM453T provide 20-50% CTR, closely matching the original performance envelope. Everlight ELM452(TA)-V and ELM453(TA)-V offer 20-50% CTR. SHARP PC457L0NIP0F provides 19-50% CTR. Renesas PS8101-F3-AX and Toshiba TLP2309 variants offer lower minimum CTR (15-35% and 15% respectively), suitable for applications with relaxed current transfer requirements.

Q: What are the temperature range implications for cross-manufacturer substitutes?

A: The original HCPL-M454-560 operates from -55°C to 100°C. Broadcom equivalents maintain this range. Vishay VOM452T/VOM453T and Renesas PS8101-F3-AX match this specification. SHARP PC457L0NIP0F operates to 85°C maximum, reducing the upper temperature margin by 15°C. Everlight ELM452(TA)-V/ELM453(TA)-V and Toshiba TLP2309 variants operate from -40°C, reducing the lower temperature margin by 15°C. Application temperature requirements must be verified against selected substitute specifications.

Q: Are all substitute parts RoHS compliant?

A: The original HCPL-M454-560 is RoHS non-compliant. All listed substitutes carry ROHS3 compliance certification, meeting current regulatory requirements for new designs and procurement. This compliance status is a key advantage of transitioning to active product alternatives.

Q: What switching time differences exist among substitutes?

A: The original HCPL-M454-560 specifies 200ns turn-on and 300ns turn-off time. Broadcom equivalents maintain this specification. Vishay VOM452T/VOM453T provide 200ns/500ns timing. SHARP PC457L0NIP0F offers 200ns/400ns. Everlight ELM452(TA)-V/ELM453(TA)-V specify 400ns/350ns. Renesas PS8101-F3-AX provides 500ns/600ns. Toshiba TLP2309 variants specify 1µs maximum for both parameters. Applications requiring fast switching should prioritize Broadcom, Vishay, or SHARP alternatives.

Q: Which substitute offers the highest output voltage capability?

A: The original HCPL-M454-560 and most substitutes specify 20V maximum output voltage. Vishay VOM452T and VOM453T provide 25V capability. Renesas PS8101-F3-AX offers the highest rating at 35V maximum output voltage, providing additional design margin for applications requiring higher collector voltage operation.

Q: What inventory considerations should guide substitute selection?

A: SHARP PC457L0NIP0F offers the highest inventory availability (71,866 units), supporting large-volume production requirements. Toshiba TLP2309(TPL,E) provides substantial stock (22,621 units). Vishay VOM452T (18,600 units) and Everlight ELM453(TA)-V (10,100 units) offer good availability. Renesas PS8101-F3-AX (3,600 units) and Toshiba TLP2309(E) (796 units) represent lower-volume alternatives. Broadcom HCPL-M454-560E (1,135 units) and HCPL-M454-500E (1,730 units) provide moderate stock levels.
