ACPL-M43T-560E Equivalent & Substitute Parts

Part Overview

The ACPL-M43T-560E is an automotive-grade optoisolator with transistor output manufactured by Broadcom Limited. This component provides 4000Vrms isolation in a 5-SO package and is qualified to AEC-Q100 standards for automotive applications. The part is currently active in production with 4100 units in stock.

Equivalent and substitute parts are identified when design requirements permit relaxation of specific electrical parameters while maintaining functional compatibility within the application's isolation, switching speed, and thermal operating range constraints.

Substitute Part Grouping Explanation

Substitute parts for the ACPL-M43T-560E are classified based on the following substitution criteria:

Parametric Equivalent (Same Series, Different Packaging):

• ACPL-M43T-500E maintains identical electrical specifications including 4000Vrms isolation, current transfer ratio range (32%-100% @ 10mA), switching times (150ns/500ns), and automotive AEC-Q100 qualification. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). This part is functionally interchangeable for applications where packaging format does not constrain procurement or assembly processes.

Manufacturer Recommended Substitute (Cross-Manufacturer Alternative):

• TLP109(IGM-TPR,E from Toshiba Semiconductor and Storage operates within acceptable parameter tolerances for applications where isolation voltage can be reduced from 4000Vrms to 3750Vrms. This part maintains the same output type (transistor), maximum output voltage (20V), output current (8mA), and package form factor (6-SO, 5 Lead). However, the current transfer ratio range (25%-75% @ 10mA) is narrower, and switching times are slower (450ns/450ns). The operating temperature range extends to -55°C, providing broader low-temperature capability. This substitute is suitable only when the 250Vrms isolation reduction and slower switching characteristics are acceptable to the application design.

Parameter Comparison

Engineering Selection Recommendations

ACPL-M43T-500E Selection Criteria: This part is the direct parametric equivalent and is recommended as the primary substitute when the ACPL-M43T-560E is unavailable. Both parts carry identical AEC-Q100 automotive qualification and ROHS3 compliance. Selection between these parts depends solely on packaging availability and procurement logistics, as electrical performance and reliability characteristics are equivalent.

TLP109(IGM-TPR,E Selection Criteria: This cross-manufacturer substitute is suitable only when all of the following conditions are met:

• Application isolation voltage requirement can be reduced from 4000Vrms to 3750Vrms
• Switching speed tolerance permits 450ns turn-on and turn-off times (versus 150ns/500ns for the primary part)
• Current transfer ratio operating window of 25%-75% @ 10mA is acceptable to circuit design
• Extended low-temperature operation to -55°C provides design benefit

The TLP109(IGM-TPR,E does not carry specified automotive grade or AEC-Q100 qualification. Use of this part in automotive applications requires independent qualification assessment and design validation.

Frequently Asked Questions (FAQ)

Q: Can ACPL-M43T-500E be used as a direct replacement for ACPL-M43T-560E?

A: Yes. Both parts are manufactured by Broadcom Limited within the R²Coupler™ series and share identical electrical specifications, isolation voltage (4000Vrms), current transfer ratio range (32%-100% @ 10mA), switching times (150ns/500ns), and AEC-Q100 automotive qualification. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Functional compatibility is complete.

Q: What are the key differences between ACPL-M43T-560E and TLP109(IGM-TPR,E?

A: The primary differences are isolation voltage (4000Vrms versus 3750Vrms), current transfer ratio range (32%-100% versus 25%-75% @ 10mA), and switching speed (150ns/500ns versus 450ns/450ns). The TLP109(IGM-TPR,E provides extended low-temperature operation (-55°C minimum versus -40°C). The TLP109 does not carry specified automotive grade or AEC-Q100 qualification.

Q: Are there package compatibility concerns when substituting TLP109(IGM-TPR,E?

A: The TLP109(IGM-TPR,E uses a 6-SOIC package with 4.55mm width, compared to 4.40mm width for the ACPL-M43T-560E. While both are 5-lead configurations, the 0.15mm width difference may affect PCB layout and assembly processes. Physical footprint validation is required before design implementation.

Q: Which substitute part is recommended for automotive applications?

A: ACPL-M43T-500E is the recommended substitute for automotive applications, as it maintains full AEC-Q100 qualification and identical electrical specifications. TLP109(IGM-TPR,E lacks specified automotive grade and AEC-Q100 qualification and requires independent qualification assessment for automotive use.

Q: Can TLP109(IGM-TPR,E be used if isolation voltage is not a critical parameter?

A: TLP109(IGM-TPR,E can be considered only if the application design permits the 250Vrms isolation reduction, accepts the narrower current transfer ratio range (25%-75%), and tolerates slower switching times (450ns). Additionally, the absence of automotive grade and AEC-Q100 qualification must be addressed through design validation and risk assessment specific to the application environment.
