Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PS9117-A is determined by the following critical parameters:

1. Isolation Voltage (3750Vrms) - Must meet or exceed the minimum isolation specification
2. Package Compatibility (5-SO) - Physical and electrical footprint must match the original 6-SOIC (0.173", 4.40mm Width), 5 Leads configuration
3. Number of Channels (1) - Single-channel configuration required
4. Output Type - Open Collector output or functionally compatible topology (Schottky-clamped open collector acceptable for improved performance characteristics)
5. Input Type (DC) - DC input requirement maintained across substitutes
6. Common Mode Transient Immunity (≥15kV/µs) - Minimum 15kV/µs CMTI specification
7. Data Rate Compatibility (10Mbps) - Must support minimum 10Mbps operation
8. Supply Voltage Compatibility (4.5V ~ 5.5V) - Supply range must encompass the original specification window

The identified substitute parts ACPL-M46T-000E, ACPL-M62L-000E, and ACPL-M62L-500E meet these substitution criteria through equivalent or superior electrical performance while maintaining package compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three identified substitutes (ACPL-M46T-000E, ACPL-M62L-000E, ACPL-M62L-500E) are manufactured by Broadcom Limited with Active product status, providing secure long-term availability compared to the Obsolete PS9117-A.

ACPL-M46T-000E provides the highest isolation voltage rating (4000Vrms) with Automotive-grade qualification and AEC-Q100 certification, suitable for applications requiring enhanced electrical margin and compliance with automotive reliability standards. The Schottky-clamped open collector output offers improved switching performance. Extended supply voltage range (4.5V ~ 30V) accommodates broader circuit topology requirements. Note: Propagation delay is specified at 550ns maximum, representing an increase from the PS9117-A specification.

ACPL-M62L-000E and ACPL-M62L-500E maintain exact isolation voltage matching (3750Vrms) with superior Common Mode Transient Immunity (20kV/µs versus 15kV/µs) and lower propagation delay (80ns maximum). Both parts employ Open Drain output topology. The electrical specifications of ACPL-M62L-000E and ACPL-M62L-500E are identical; differentiation is packaging only (Tube versus Tape & Reel). Wide supply voltage range (2.7V ~ 5.5V) extends lower-voltage circuit compatibility. Extended operating temperature range (-40°C ~ 105°C) exceeds the PS9117-A specification.

All substitutes maintain ROHS3 Compliance and EAR99 export classification equivalence with the original part.

Frequently Asked Questions (FAQ)

Q: Can ACPL-M46T-000E, ACPL-M62L-000E, and ACPL-M62L-500E be used interchangeably with PS9117-A?

A: Direct interchangeability requires verification of output topology compatibility. ACPL-M46T-000E features open collector output (matching PS9117-A), while ACPL-M62L-000E and ACPL-M62L-500E employ open drain topology. Circuit designs utilizing open drain outputs require pull-up resistor configuration; designs dependent on open collector behavior may require topology evaluation. Package footprint compatibility (5-SO) and pin assignment equivalence enable physical substitution.

Q: What is the difference between ACPL-M62L-000E and ACPL-M62L-500E?

A: These parts are electrically identical with identical supplier device package specifications (5-SO). Differentiation is packaging configuration only: ACPL-M62L-000E is supplied in Tube format, while ACPL-M62L-500E is supplied in Tape & Reel format. Selection depends on production volume and handling requirements.

Q: Are these substitute parts qualified for automotive applications?

A: ACPL-M46T-000E carries Automotive grade designation with AEC-Q100 qualification. ACPL-M62L-000E and ACPL-M62L-500E do not specify automotive qualification. Automotive application requirements necessitate component qualification verification against applicable standards.

Q: How do propagation delay specifications affect circuit timing?

A: The PS9117-A specifies 75ns maximum propagation delay. ACPL-M46T-000E specifies 550ns maximum, representing approximately 475ns additional delay. ACPL-M62L-000E and ACPL-M62L-500E specify 80ns maximum, providing timing characteristics within 5ns of the original part. System-level timing margin analysis is required when substituting parts with different propagation delay specifications.

Q: What current output levels are supported?

A: The PS9117-A supports 25mA output current. ACPL-M46T-000E supports 15mA, and ACPL-M62L-000E and ACPL-M62L-500E support 10mA. Circuit designs dependent on higher output current capabilities must be re-evaluated to confirm load-driving capability remains within specification margins.

Q: Are these parts RoHS compliant?

A: ACPL-M46T-000E, ACPL-M62L-000E, and ACPL-M62L-500E all satisfy ROHS3 Compliance requirements. The PS9117-A status was not specified in the provided data.
