Key Parameters

Substitute Part Grouping Explanation

Substitution criteria for the PS9317L2-E3-AX are based on the following key electrical and mechanical parameters:

Primary Substitution Parameters:

• Voltage - Isolation: 5000Vrms (exact match required)
• Common Mode Transient Immunity: 15kV/µs (exact match required)
• Number of Channels: 1 (exact match required)
• Input Type: DC (exact match required)
• Output Type: Open Collector (exact match or enhanced capability acceptable)
• Package / Case: 6-SOIC with 6.80mm width (mechanical compatibility)
• Mounting Type: Surface Mount (exact match required)
• RoHS Status: ROHS3 Compliant (compliance continuity)

Substitutes are grouped into two categories based on isolation voltage and output characteristics:

Category 1: 5000Vrms Isolation (Direct Electrical Substitutes) ACPL-W456-000E and ACPL-W456-500E maintain the 5000Vrms isolation voltage with Open Collector, Schottky Clamped output topology. These parts provide direct electrical compatibility with enhanced transient immunity and extended temperature operating range.

Category 2: Renesas NEPOC Series Alternatives PS9313L-E3-AX and PS9313L2-AX are from the same Renesas NEPOC series with matching 5000Vrms isolation and identical mechanical packaging. These maintain the original open collector output without Schottky clamping.

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes with Full Compatibility: PS9313L-E3-AX and PS9313L2-AX are the most compatible alternatives, maintaining identical isolation voltage (5000Vrms), mechanical package dimensions (0.268" × 6.80mm), and standard open collector output topology. Both are ROHS3 compliant with unlimited moisture sensitivity rating. PS9313L-E3-AX carries active product status from Renesas Electronics Corporation, supporting long-term design continuity.

Broadcom ACPL-W456 Series (5000Vrms Isolation): ACPL-W456-000E and ACPL-W456-500E provide direct isolation voltage equivalence to the PS9317L2-E3-AX with identical 15kV/µs CMTI specification. Both incorporate Schottky clamping in the output stage and support extended supply voltage range (4.5V to 30V) and higher operating temperature limits (-40°C to 100°C). PCB layout consideration required due to package width difference (0.295" versus 0.268").

Broadcom ACPL-P456 Series (3750Vrms Isolation): ACPL-P456-000E and ACPL-P456-500E maintain mechanical and electrical compatibility with the exception of reduced isolation voltage (3750Vrms versus 5000Vrms). These substitutes are applicable only in applications where the lower isolation specification is acceptable within circuit design margins and regulatory compliance requirements.

Propagation Delay Consideration: The PS9317L2-E3-AX operates at 10Mbps with 75ns maximum propagation delay. All substitute parts exhibit longer propagation delays (400-750ns range), rendering them incompatible with applications requiring the original 10Mbps data rate performance specification. Substitution is appropriate only for circuits operating at lower data rates or where timing margins accommodate extended delays.

Frequently Asked Questions (FAQ)

Q: Can ACPL-W456-000E and ACPL-W456-500E be used as drop-in replacements? A: Electrical compatibility is established through matching 5000Vrms isolation, 15kV/µs CMTI, single channel DC input, and open collector output. Physical substitution requires PCB layout verification due to package width difference (7.50mm versus 6.80mm). Extended supply voltage range (4.5V to 30V) and higher temperature rating provide design flexibility. Propagation delay differences must be evaluated against timing requirements.

Q: What is the difference between ACPL-W456-000E (Tube) and ACPL-W456-500E (Tape & Reel)? A: Both variants are electrically and mechanically identical. The distinction is packaging format: Tube packaging is supplied in plastic tubes for manual handling and small-quantity applications, while Tape & Reel (TR) packaging is configured for automated assembly equipment. Selection depends on manufacturing process requirements and order quantity.

Q: Why do the Renesas alternatives (PS9313L-E3-AX and PS9313L2-AX) show lower data rates? A: The PS9313L-E3-AX and PS9313L2-AX are rated for 1Mbps data rate with longer propagation delays (750ns, 500ns maximum) compared to the original PS9317L2-E3-AX (10Mbps, 75ns maximum). These parts are functionally compatible for applications operating at lower data rates but are unsuitable for high-speed signal isolation requirements.

Q: Is package width difference significant for ACPL-W456 substitution? A: The ACPL-W456 series uses 6-SOIC packaging with 7.50mm width versus the 6.80mm width of the original PS9317L2-E3-AX. This dimension difference requires PCB layout review to confirm footprint compatibility. Pin pitch and contact locations remain standardized 6-SOIC configuration.

Q: Can ACPL-P456 series (3750Vrms) be used when 5000Vrms isolation is specified? A: ACPL-P456 substitution is contingent on application-level isolation voltage requirements. If the circuit design or regulatory standard mandates 5000Vrms isolation, these lower-rated parts do not meet specification. Substitution is only permissible when design review confirms adequate margin with reduced isolation voltage.

Q: What does "Not For New Designs" status mean for PS9313L2-AX? A: This designation indicates that Renesas does not recommend this part for incorporation into new product designs. While existing inventory remains available, the part is in end-of-life status. PS9313L-E3-AX (Active status) is the preferred Renesas alternative for new design implementations.

Q: Are supply voltage range differences important? A: The PS9317L2-E3-AX operates within 4.5V to 5.5V supply range. Broadcom alternatives support extended range (4.5V to 30V), and Renesas alternatives support 4.5V to 20V. If circuit design is constrained to the original 4.5V to 5.5V specification, broader supply voltage capability does not introduce compatibility issues. Extended range provides additional flexibility for multi-voltage systems.
