Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PS9117A-F3-AX is determined by the following critical parameters:

Primary Compatibility Criteria:

• Single channel configuration (1 channel required)
• Surface mount packaging in 5-SO form factor with 6-SOIC physical dimensions
• Isolation voltage rating of 3750Vrms or higher
• Common mode transient immunity of 15kV/µs or greater
• Open collector or open drain output topology
• DC input type
• Operating temperature range encompassing -40°C minimum
• RoHS3 compliance and REACH unaffected status

Substitute Categories:

Group 1: Direct Functional Equivalents (Open Collector, 4000Vrms)

• ACPL-M46T-000E (Broadcom, Tube packaging)
• ACPL-M46T-500E (Broadcom, Cut Tape & Digi-Reel packaging)

These parts maintain open collector output configuration with enhanced isolation voltage (4000Vrms vs. 3750Vrms) and identical CMTI rating (15kV/µs). Output current is reduced to 15mA. Supply voltage range extends to 30V. Automotive grade with AEC-Q100 qualification. Operating temperature extends to 125°C.

Group 2: Functional Equivalents (Open Drain, 3750Vrms)

• ACPL-M62L-000E (Broadcom, Tube packaging)
• ACPL-M62L-500E (Broadcom, Tape & Reel packaging)

These parts match isolation voltage (3750Vrms) and data rate (10MBd) with open drain output topology. CMTI enhanced to 20kV/µs. Output current reduced to 10mA. Supply voltage range extends to 2.7V minimum. Operating temperature limited to 105°C maximum.

Parameter Comparison

Engineering Selection Recommendations

For ACPL-M46T-000E and ACPL-M46T-500E Selection:

These Broadcom R²Coupler™ series optoisolators are active products with automotive-grade qualification (AEC-Q100) and extended operating temperature range to 125°C. The 4000Vrms isolation voltage exceeds the PS9117A-F3-AX requirement. Schottky clamping on the open collector output provides enhanced switching performance. The extended supply voltage range (4.5V to 30V) accommodates broader system designs. Primary design consideration: output current is reduced from 25mA to 15mA, requiring load impedance adjustment. Propagation delay increases from 75ns to 550ns, affecting timing-critical applications. Packaging options include Tube (ACPL-M46T-000E) and Cut Tape & Digi-Reel (ACPL-M46T-500E) for different procurement workflows.

For ACPL-M62L-000E and ACPL-M62L-500E Selection:

These Broadcom optoisolators maintain the original 3750Vrms isolation voltage and 10MBd data rate with enhanced CMTI (20kV/µs vs. 15kV/µs). Open drain output topology differs from open collector configuration, requiring circuit-level evaluation for pull-up resistor compatibility. Output current reduced to 10mA necessitates load impedance verification. Operating temperature maximum of 105°C is lower than ACPL-M46 series but exceeds the original PS9117A-F3-AX specification. Supply voltage minimum extends to 2.7V, enabling low-power applications. Propagation delay of 80ns closely matches the original 75ns specification. Packaging options include Tube (ACPL-M62L-000E) and Tape & Reel (ACPL-M62L-500E).

Compliance Status:

All substitute parts maintain RoHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the discontinued PS9117A-F3-AX.

Frequently Asked Questions (FAQ)

Q1: Can ACPL-M46T series parts directly replace PS9117A-F3-AX in existing designs?

A: Physical package compatibility is confirmed (6-SOIC, 5-SO form factor, identical pin count). Functional compatibility requires circuit-level evaluation due to reduced output current (15mA vs. 25mA) and increased propagation delay (550ns vs. 75ns). Open collector output topology is maintained. Load impedance and timing margins must be verified against design specifications.

Q2: What is the primary difference between ACPL-M46T and ACPL-M62L substitute options?

A: ACPL-M46T series maintains open collector output with higher isolation voltage (4000Vrms) and automotive qualification. ACPL-M62L series matches the original isolation voltage (3750Vrms) and data rate (10MBd) but uses open drain output topology with enhanced CMTI (20kV/µs). Output current differs: 15mA (ACPL-M46T) vs. 10mA (ACPL-M62L). Selection depends on output topology requirements and isolation voltage margin needs.

Q3: Are packaging variants (Tube, Cut Tape, Tape & Reel) electrically equivalent?

A: Yes. ACPL-M46T-000E (Tube) and ACPL-M46T-500E (Cut Tape & Digi-Reel) are electrically identical. ACPL-M62L-000E (Tube) and ACPL-M62L-500E (Tape & Reel) are electrically identical. Packaging differences affect procurement, handling, and automated assembly processes only. Electrical specifications and performance characteristics remain unchanged.

Q4: What design considerations apply when substituting from 25mA to 15mA or 10mA output current?

A: Output current reduction directly impacts load impedance calculations. Pull-up resistor values and load capacitance must be recalculated to maintain signal integrity and timing margins. Verify that the reduced current capability meets the driven circuit's input current requirements. Propagation delay specifications should be re-evaluated against system timing budgets, particularly for ACPL-M46T series with 550ns delay.

Q5: Is the open drain output of ACPL-M62L series compatible with open collector circuit designs?

A: Both topologies function as current sinks with external pull-up resistors. Circuit-level compatibility depends on pull-up voltage, load impedance, and switching speed requirements. Open drain typically exhibits faster switching characteristics. Verify pull-up resistor sizing and load capacitance compatibility. Schottky clamping present in ACPL-M46T series provides additional transient protection not present in ACPL-M62L open drain configuration.

Q6: What is the significance of the extended operating temperature range in ACPL-M46T series?

A: ACPL-M46T parts operate to 125°C maximum, exceeding the original PS9117A-F3-AX specification (85°C). This extended range provides thermal margin for high-ambient or high-power applications. Automotive-grade qualification (AEC-Q100) ensures reliability in demanding environments. Applications limited to 85°C operation gain additional thermal headroom for component longevity.

Q7: How does the extended supply voltage range (4.5V to 30V) in ACPL-M46T affect system design?

A: The broader supply voltage range enables use in systems with variable or elevated supply voltages beyond the original 4.5V to 5.5V specification. This flexibility supports multi-voltage platform designs. However, the original PS9117A-F3-AX design must be verified to operate within the substitute part's supply range. No design changes are required if the original supply voltage remains within 4.5V to 5.5V.

Q8: What inventory status should influence substitution decisions?

A: ACPL-M46T-500E (5766 Pcs) and ACPL-M62L-000E (16100 Pcs) offer substantial inventory availability. ACPL-M46T-000E (1420 Pcs) and ACPL-M62L-500E (2200 Pcs) have lower stock levels. All substitute parts are active products with ongoing manufacturing support, unlike the discontinued PS9117A-F3-AX. Procurement strategy should consider lead times and volume requirements for production schedules.
