Key Parameters

Substitute Part Grouping Explanation

Substitute optoisolators for the PS9113-F3-AX are selected based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Voltage - Isolation: 3750Vrms (exact match required)
• Number of Channels: 1 (single channel configuration)
• Output Type: Open Collector (standard or Schottky Clamped variants acceptable)
• Package / Case: 6-SOIC, 5 Leads (identical form factor)
• Common Mode Transient Immunity: 15kV/µs or higher
• Current - Output / Channel: 15 mA minimum

Secondary Compatibility Factors:

• Voltage - Supply: 4.5V minimum required; extended range acceptable
• Operating Temperature: -40°C ~ 100°C or compatible subset
• RoHS3 Compliance: Required for regulatory alignment
• Propagation Delay: Lower values indicate improved performance
• Data Rate: 1Mbps or higher acceptable for digital signal applications

The HCPL-M456-000E, HCPL-M456-500E, and HCPL-M611-560E all meet these substitution criteria with identical isolation voltage, channel count, package configuration, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

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

These optoisolators provide direct functional equivalence to the PS9113-F3-AX with improved propagation delay characteristics (550ns/400ns versus 750ns/500ns). Both parts maintain identical isolation voltage, channel count, output configuration, and operating temperature range. The extended supply voltage range (4.5V ~ 30V) accommodates broader system designs compared to the original part specification.

HCPL-M456-000E is packaged in Tube format, while HCPL-M456-500E is supplied in Cut Tape and Digi-Reel formats. Both are ROHS3 compliant and currently in active production status with substantial inventory availability (6600 and 16315 units respectively).

HCPL-M611-560E (Broadcom Limited)

This optoisolator offers enhanced performance characteristics including 10MBd data rate capability, significantly reduced propagation delay (75ns/75ns), and increased output current capacity (50 mA versus 15 mA). The common mode transient immunity specification is 10kV/µs, which is lower than the PS9113-F3-AX requirement of 15kV/µs.

The HCPL-M611-560E operates within a narrower supply voltage range (4.5V ~ 5.5V) and reduced operating temperature maximum (85°C versus 100°C). This part is suitable for applications where the lower CMTI specification and temperature constraints are acceptable, and where the enhanced speed and output current capabilities provide system benefits.

All three substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding, ensuring regulatory and compliance alignment with the original PS9113-F3-AX specification.

Frequently Asked Questions (FAQ)

Q: Can HCPL-M456-000E and HCPL-M456-500E be used interchangeably with PS9113-F3-AX?

A: Yes. Both HCPL-M456 variants maintain identical isolation voltage (3750Vrms), channel count (1), output type (open collector), package configuration (6-SOIC, 5 Leads), and operating temperature range (-40°C ~ 100°C). The improved propagation delay characteristics (550ns/400ns) represent enhanced performance. The primary difference is packaging format: HCPL-M456-000E is supplied in Tube, while HCPL-M456-500E is supplied in Cut Tape and Digi-Reel formats.

Q: What are the key differences between HCPL-M456 and HCPL-M611-560E?

A: The HCPL-M611-560E provides higher data rate capability (10MBd), significantly faster propagation delay (75ns/75ns), and higher output current (50 mA). However, it specifies lower common mode transient immunity (10kV/µs versus 15kV/µs), operates within a narrower supply voltage range (4.5V ~ 5.5V), and has a reduced maximum operating temperature (85°C versus 100°C). Selection depends on whether the application requires the lower CMTI specification and temperature constraints.

Q: Are all substitute parts pin-compatible with PS9113-F3-AX?

A: Yes. All substitute parts use the identical 6-SOIC package with 5 leads, ensuring direct pin-for-pin compatibility. PCB layout modifications are not required for substitution.

Q: What is the significance of Schottky Clamped output in the Broadcom substitutes?

A: Schottky clamping in the output stage reduces propagation delay and improves switching speed characteristics. This is a performance enhancement that does not affect functional compatibility with applications designed for standard open collector outputs.

Q: Which substitute part should be selected for new designs?

A: For applications requiring the original PS9113-F3-AX specifications (1Mbps data rate, 15kV/µs CMTI, 15 mA output current, -40°C ~ 100°C operating range), HCPL-M456-000E or HCPL-M456-500E are recommended. Both are in active production with superior propagation delay performance. HCPL-M611-560E is suitable only when the application can accommodate lower CMTI specification, narrower supply voltage range, and reduced temperature maximum, while benefiting from higher speed and output current capabilities.

Q: What inventory considerations apply to these substitutes?

A: HCPL-M456-500E has the highest inventory availability (16315 units), followed by HCPL-M456-000E (6600 units) and HCPL-M611-560E (4017 units). All three parts are currently in active production status with no supply constraints anticipated.
