PS9113-AX Equivalent & Substitute Parts

Part Overview

The PS9113-AX is a logic output optoisolator manufactured by CEL, featuring 3750Vrms isolation voltage, open collector output configuration, and 1Mbps data rate capability. This component is designed for applications requiring galvanic isolation in digital signal transmission with high common mode transient immunity (15kV/µs). The PS9113-AX is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines to maintain design continuity and ensure supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS9113-AX is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Isolation voltage: 3750Vrms (exact match required)
• Number of channels: 1 (single channel configuration)
• Output type: Open collector topology
• Package / Case: 6-SOIC (0.173", 4.40mm Width), 5 Leads (identical footprint)
• Input type: DC
• Mounting type: Surface Mount

Secondary Compatibility Parameters:

• Common mode transient immunity: 15kV/µs minimum
• Current - output / channel: 15 mA minimum
• Voltage - supply: Range must encompass 4.5V ~ 20V
• Operating temperature: -40°C ~ 100°C minimum range

The substitute parts HCPL-M456-000E, HCPL-M456-500E, and HCPL-M611-560E meet the primary equivalence criteria and maintain compatibility with the electrical and mechanical specifications of the PS9113-AX. Variations in secondary parameters (propagation delay, data rate, CMTI, output current) reflect design improvements in active product lines while preserving functional interchangeability within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

HCPL-M456-000E and HCPL-M456-500E (Broadcom Limited)

These parts are direct functional equivalents to the PS9113-AX. Both maintain identical isolation voltage (3750Vrms), channel count (1), output configuration (open collector with Schottky clamping), CMTI (15kV/µs), output current (15 mA), and package footprint. The HCPL-M456 series offers improved propagation delay characteristics (550ns/400ns versus 750ns/500ns) and extended supply voltage range (4.5V ~ 30V). Both parts are in active production status with ROHS3 compliance. HCPL-M456-000E is supplied in Tube packaging, while HCPL-M456-500E is available in Cut Tape (CT) & Digi-Reel® format. Selection between these two variants depends on procurement and assembly requirements.

HCPL-M611-560E (Broadcom Limited)

This part provides enhanced performance characteristics including higher data rate (10MBd), faster propagation delay (75ns), and increased output current capability (50 mA). However, the HCPL-M611-560E operates within a restricted supply voltage range (4.5V ~ 5.5V) and reduced operating temperature maximum (85°C versus 100°C). The CMTI specification is reduced to 10kV/µs. This part is suitable for applications where the PS9113-AX supply voltage and temperature range requirements do not exceed 5.5V and 85°C respectively, and where enhanced speed performance is beneficial.

All substitute parts are ROHS3 compliant and maintain identical package geometry, enabling direct PCB footprint compatibility with the PS9113-AX.

Frequently Asked Questions (FAQ)

Q: Can HCPL-M456-000E and HCPL-M456-500E be used interchangeably with PS9113-AX?

A: Yes. Both parts meet all primary equivalence criteria: 3750Vrms isolation, single channel, open collector output, 15kV/µs CMTI, 15 mA output current, and identical 6-SOIC package footprint. The difference between these two variants is packaging format (Tube versus Cut Tape & Digi-Reel®), not electrical performance.

Q: What are the key differences between HCPL-M456 and HCPL-M611 series?

A: The HCPL-M611-560E offers superior speed performance (10MBd data rate, 75ns propagation delay) and higher output current (50 mA) compared to HCPL-M456 variants. However, HCPL-M611-560E has a narrower supply voltage range (4.5V ~ 5.5V versus 4.5V ~ 30V) and lower maximum operating temperature (85°C versus 100°C). CMTI is also reduced from 15kV/µs to 10kV/µs.

Q: Is the PS9113-AX footprint compatible with substitute parts?

A: Yes. All substitute parts use the identical 6-SOIC (0.173", 4.40mm Width), 5-lead package. Direct PCB footprint compatibility is confirmed.

Q: What is the impact of Schottky clamping in HCPL-M456 and HCPL-M611 variants?

A: Schottky clamping is an output stage enhancement that improves switching speed and reduces propagation delay compared to the PS9113-AX. This feature does not affect functional compatibility; it represents a design improvement in the substitute parts.

Q: Are there supply voltage compatibility concerns when substituting PS9113-AX?

A: The PS9113-AX operates at 4.5V ~ 20V. HCPL-M456 variants support 4.5V ~ 30V (fully compatible). HCPL-M611-560E operates at 4.5V ~ 5.5V only. If your application requires supply voltages above 5.5V, use HCPL-M456 variants. If supply voltage is constrained to 4.5V ~ 5.5V, HCPL-M611-560E is acceptable.

Q: What is the significance of RoHS3 compliance in substitute parts?

A: The PS9113-AX is RoHS non-compliant. All substitute parts (HCPL-M456-000E, HCPL-M456-500E, HCPL-M611-560E) are ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and procurement.

Q: Can HCPL-M611-560E be used in applications requiring -40°C ~ 100°C operating temperature?

A: No. HCPL-M611-560E maximum operating temperature is 85°C. If your application requires operation up to 100°C, use HCPL-M456-000E or HCPL-M456-500E.

Q: What inventory availability should be considered?

A: HCPL-M456-500E has the highest inventory (16,315 pcs), followed by HCPL-M456-000E (6,600 pcs) and HCPL-M611-560E (4,017 pcs). All parts are in active production status.
