Engineering Selection Recommendations

Direct Isolation Equivalents (5000Vrms): ACPL-W340-000E and ACPL-W340-060E match the 5000Vrms isolation specification of the PS9308L2-E3-AX. The ACPL-W340-000E is packaged in Tube and ACPL-W340-060E in Tube, with active product status and CSA/UR certifications. Output current for these variants is limited to 1A peak, which is lower than the original 2A specification.

Extended Output Current Equivalents (3750Vrms): ACPL-P341 series devices (ACPL-P341-000E, ACPL-P341-060E, ACPL-P341-500E, ACPL-P341-560E) provide 3A peak output current, exceeding the PS9308L2-E3-AX 2A specification. Isolation voltage is reduced to 3750Vrms. All variants are active with CSA/UR or CSA/IEC/EN/DIN/UR certifications.

Standard Output Current Equivalents (3750Vrms): ACPL-P340 series devices (ACPL-P340-000E, ACPL-P340-060E, ACPL-P340-500E, ACPL-P340-560E) provide 1A peak output current with 3750Vrms isolation. All are active with CSA/UR or CSA/IEC/EN/DIN/UR certifications.

All substitute parts are ROHS3 compliant and operate within the 15V ~ 30V output supply range. Operating temperature range is -40°C to 105°C for substitutes versus -40°C to 110°C for the original part.

Frequently Asked Questions (FAQ)

Q: Can ACPL-W340 devices replace the PS9308L2-E3-AX directly? A: ACPL-W340 devices maintain the 5000Vrms isolation specification but provide reduced output current (1A peak versus 2A peak). They are pin-compatible in the 6-SOIC package and suitable for applications where 1A output current meets the circuit requirements.

Q: What is the difference between ACPL-P340 and ACPL-P341 series? A: Both series provide 3750Vrms isolation in 6-SOIC package. ACPL-P340 variants supply 1A peak output current, while ACPL-P341 variants supply 3A peak output current. The ACPL-P341 series exceeds the original 2A specification, providing additional output current margin.

Q: Does isolation voltage downgrade from 5000Vrms to 3750Vrms affect substitution viability? A: Isolation voltage selection depends on circuit isolation requirements. Applications with 3750Vrms isolation specifications can use ACPL-P340 or ACPL-P341 devices. Applications with 5000Vrms isolation requirements must use ACPL-W340 devices. The isolation voltage specification is determined by the application's maximum voltage differential and safety standards.

Q: Are all substitute parts available in the same packaging options? A: Packaging varies by part number variant. ACPL-P340-000E and ACPL-P340-060E are supplied in Tube. ACPL-P340-500E is supplied in Cut Tape (CT) & Digi-Reel. ACPL-P341-000E and ACPL-P341-060E are supplied in Tube. ACPL-P341-500E is supplied in Tape & Reel (TR). ACPL-P341-560E is supplied in Cut Tape (CT) & Digi-Reel. Select packaging based on manufacturing volume requirements.

Q: What certifications apply to substitute components? A: ACPL-W340 variants carry CSA and UR approvals. ACPL-P340 variants carry CSA and UR approvals or CSA, IEC/EN/DIN, and UR approvals depending on the suffix. ACPL-P341 variants carry CSA and UR approvals or CSA, IEC/EN/DIN, and UR approvals. All parts are ROHS3 compliant and REACH unaffected.

Q: How do propagation delay specifications compare? A: The PS9308L2-E3-AX specifies maximum 250ns propagation delay. All Broadcom substitutes specify maximum 200ns propagation delay, representing improved timing performance. Pulse width distortion is 100ns maximum for the original versus 70ns maximum for substitutes.
