PS9308L2-V-E3-AX Equivalent & Substitute Parts

Part Overview

The PS9308L2-V-E3-AX is a 2A gate driver optical coupler manufactured by CEL, featuring 5000Vrms isolation voltage in a 6-SDIP package. This component is discontinued at DiGi Electronics and no longer in active production. The part provides single-channel gate drive functionality with optical isolation suitable for high-voltage switching applications requiring galvanic isolation between control and power circuits.

Due to the discontinued status of the PS9308L2-V-E3-AX, equivalent substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Broadcom Limited offers functionally compatible alternatives within the ACPL-P340, ACPL-P341, and ACPL-W340 series that maintain core electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution logic for the PS9308L2-V-E3-AX is based on the following critical parameters:

Primary Substitution Criteria:

Isolation voltage rating (5000Vrms minimum required)
Single-channel configuration
Output supply voltage compatibility (15–30V)
Surface mount 6-SOIC package footprint compatibility
Peak output current capability (2A minimum for direct replacement)

Substitution Categories:

Category 1: Direct Electrical Equivalents (5000Vrms Isolation) The ACPL-W340 series maintains the 5000Vrms isolation voltage of the original part. These parts are suitable for applications where the higher isolation rating is a design requirement.

Category 2: Functional Alternatives (3750Vrms Isolation) The ACPL-P340 and ACPL-P341 series operate at 3750Vrms isolation voltage. These parts are suitable for applications where 3750Vrms isolation meets system requirements and cost optimization is a consideration.

Output Current Capability Variants:

ACPL-P340 series: 1A peak output current
ACPL-P341 series: 3A peak output current
ACPL-W340 series: 1A peak output current

The PS9308L2-V-E3-AX with 2A peak output current can be substituted by ACPL-P341 series (3A capability) or ACPL-W340 series (1A capability, with design review for current margin).

Engineering Selection Recommendations

For Direct Replacement (Isolation Voltage Critical): Select ACPL-W340-000E, ACPL-W340-060E when the 5000Vrms isolation rating is a mandatory design requirement. These parts maintain electrical isolation equivalence to the PS9308L2-V-E3-AX. All ACPL-W340 variants are in active production status with CSA and UR certifications.

For Functional Substitution (3750Vrms Acceptable): Select ACPL-P341-000E, ACPL-P341-060E, ACPL-P341-500E, or ACPL-P341-560E when system design permits 3750Vrms isolation and higher output current capability (3A peak) is beneficial. These parts exceed the 2A output current requirement of the original part and are in active production.

For Cost-Optimized Substitution (Lower Current Acceptable): Select ACPL-P340-000E, ACPL-P340-060E, ACPL-P340-500E, or ACPL-P340-560E when 3750Vrms isolation is acceptable and output current requirements do not exceed 1A peak. These parts are in active production with multiple packaging options.

Compliance Considerations: All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the environmental compliance profile of the original PS9308L2-V-E3-AX. Broadcom parts carry CSA and UR certifications; ACPL-P340-060E and ACPL-P341-060E include additional IEC/EN/DIN approvals.

Temperature Range Consideration: The PS9308L2-V-E3-AX operates to +110°C maximum. Substitute parts operate to +105°C maximum. Applications requiring operation above +105°C require design review.

Frequently Asked Questions (FAQ)

Q: Can ACPL-P340 series parts directly replace the PS9308L2-V-E3-AX?

A: ACPL-P340 series parts are functionally compatible for single-channel gate drive applications. However, they operate at 3750Vrms isolation (versus 5000Vrms) and provide 1A peak output current (versus 2A). Substitution is valid when system isolation voltage requirements permit 3750Vrms and output current does not exceed 1A.

Q: What is the difference between ACPL-P341 and ACPL-P340 series?

A: Both series operate at 3750Vrms isolation. The ACPL-P341 series provides 3A peak output current and 2.5A output high/low current. The ACPL-P340 series provides 1A peak output current and 0.8A output high/low current. Select ACPL-P341 for applications requiring higher gate drive current.

Q: Why do ACPL-W340 parts cost more than ACPL-P340 parts?

A: ACPL-W340 series maintains the 5000Vrms isolation voltage of the original PS9308L2-V-E3-AX, providing direct electrical equivalence. ACPL-P340 series operates at lower 3750Vrms isolation. The higher isolation rating in ACPL-W340 justifies the cost difference for applications where 5000Vrms isolation is required.

Q: Are there package differences between PS9308L2-V-E3-AX and substitute parts?

A: The PS9308L2-V-E3-AX uses 6-SDIP package. All Broadcom substitute parts use 6-SOIC (0.268", 6.80mm width) package. Both packages are surface mount with compatible pinout for gate driver applications. PCB layout review is required to confirm footprint compatibility.

Q: What packaging options are available for substitute parts?

A: Broadcom substitute parts are available in Tube, Tape & Reel (TR), and Cut Tape (CT) & Digi-Reel® packaging. Specific part number suffixes indicate packaging: -000E (Tube), -060E (Tube with IEC/EN/DIN), -500E (Tape & Reel or Cut Tape), -560E (Cut Tape & Digi-Reel®).

Q: Do all substitute parts have the same certifications as the original PS9308L2-V-E3-AX?

A: All substitute parts are ROHS3 compliant and REACH unaffected. The PS9308L2-V-E3-AX carries CSA, SEMKO, UL, and VDE approvals. Broadcom parts carry CSA and UR certifications. ACPL-P340-060E and ACPL-P341-060E include additional IEC/EN/DIN approvals. Application-specific certification requirements should be verified.

Q: Can ACPL-W340-000E be used in all applications where PS9308L2-V-E3-AX was used?

A: ACPL-W340-000E is electrically compatible for applications requiring 5000Vrms isolation and up to 1A peak output current. Applications originally designed for 2A peak output current require design review to confirm 1A capability is sufficient. Operating temperature range is −40°C to +105°C (versus −40°C to +110°C for original part).

Q: What is the inventory status of substitute parts?

A: All listed Broadcom substitute parts are in active production with current inventory available. ACPL-P341-000E: 2082 pcs, ACPL-P341-500E: 2100 pcs, ACPL-W340-000E: 1860 pcs. Inventory levels vary by packaging option and distributor. Verify current availability with component suppliers.
