ACPL-M61T-500 Equivalent & Substitute Parts

Part Overview

The ACPL-M61T-500 is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. This 4000Vrms isolation device features open collector output with Schottky clamping, 10MBd data rate, and automotive-grade qualification (AEC-Q100). The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ACPL-M61T-500 is determined by the following critical parameters:

Primary Criteria (Must Match):

• Single channel configuration
• Open collector output topology
• DC input type
• Surface mount 5-lead package (6-SOIC form factor)
• Automotive grade qualification
• Operating temperature range -40°C ~ 125°C

Secondary Criteria (Allowable Variance):

• Isolation voltage: minimum 3750Vrms (ACPL-M61T-500 specifies 4000Vrms)
• Common mode transient immunity: minimum 15kV/µs
• Data rate: minimum 10MBd
• Output current: minimum 25 mA
• Supply voltage range: must encompass 4.5V ~ 5.5V

Two substitute parts meet these criteria: ACPL-M61T-500E (direct Broadcom equivalent) and TLP118(TPL,E) (Toshiba alternative). TLP2362(E) is listed but does not meet automotive qualification requirements.

Parameter Comparison

Engineering Selection Recommendations

ACPL-M61T-500E is the primary substitute. This part is manufactured by Broadcom Limited under the same base product number (ACPL-M61) and maintains identical electrical specifications including 4000Vrms isolation, 50mA output current, and 75ns propagation delay. The part is currently active with 72,300 units in stock and achieves ROHS3 compliance, addressing environmental regulatory requirements that the original part does not meet. Pin-for-pin compatibility and identical performance characteristics make this the direct replacement for discontinued ACPL-M61T-500 applications.

TLP118(TPL,E) is a secondary alternative for applications where reduced output current (25mA vs. 50mA) and lower isolation voltage (3750Vrms vs. 4000Vrms) are acceptable. This Toshiba part offers improved data rate (20Mbps vs. 10MBd) and faster propagation delay (60ns vs. 75ns). However, automotive qualification status is not specified in the provided data, requiring verification before use in automotive-grade designs.

TLP2362(E) does not meet automotive qualification requirements and is not recommended as a substitute for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can ACPL-M61T-500E be used as a direct replacement for ACPL-M61T-500?

A: Yes. ACPL-M61T-500E is electrically and mechanically identical to the discontinued ACPL-M61T-500, with identical isolation voltage (4000Vrms), output current (50mA), data rate (10MBd), and propagation delay (75ns). Both parts share the same base product number and package configuration.

Q: What are the key differences between ACPL-M61T-500 and TLP118(TPL,E)?

A: TLP118(TPL,E) has lower output current (25mA vs. 50mA), lower isolation voltage (3750Vrms vs. 4000Vrms), and faster data rate (20Mbps vs. 10MBd). Propagation delay is faster (60ns vs. 75ns). Both maintain 15kV/µs CMTI and identical supply voltage range. Automotive qualification status differs.

Q: Is TLP2362(E) suitable for automotive applications?

A: TLP2362(E) does not carry automotive grade qualification in the provided specifications. Use is restricted to non-automotive applications. For automotive designs, ACPL-M61T-500E is the appropriate choice.

Q: What is the impact of reduced output current in TLP118(TPL,E)?

A: TLP118(TPL,E) provides 25mA maximum output current compared to 50mA in ACPL-M61T-500. Applications requiring higher output current or driving lower impedance loads must remain on ACPL-M61T-500E or verify that 25mA meets load requirements.

Q: Are all substitute parts RoHS compliant?

A: ACPL-M61T-500E and TLP118(TPL,E) are ROHS3 compliant. TLP2362(E) is RoHS compliant. The original ACPL-M61T-500 is RoHS non-compliant.

Q: Do all parts use the same package?

A: All parts use 6-SOIC surface mount packages with 5 leads. Physical dimensions vary slightly (ACPL-M61T-500 and ACPL-M61T-500E: 0.173" width; TLP118 and TLP2362: 0.179" width), but both fit standard 6-SOIC footprints.
