Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS9114-F3-A is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Single channel configuration (1 input, 0 output on opposite side)
• Open collector output topology
• 10Mbps or higher data rate capability
• 10kV/µs common mode transient immunity
• Identical propagation delay specifications (75ns maximum for both tpLH and tpHL)
• 4.5V to 5.5V supply voltage compatibility
• Identical operating temperature range (-40°C to 85°C)
• Surface mount 6-SOIC package with 5-lead configuration

Allowable Parameter Variations:

• Isolation voltage equal to or greater than 2500Vrms
• Output current equal to or greater than 25 mA per channel
• Rise and fall time specifications within typical operating margins

The HCPL-M611-560E meets all mandatory criteria while exceeding isolation voltage (3750Vrms) and output current (50 mA) specifications, establishing it as a direct substitute.

Engineering Selection Recommendations

The HCPL-M611-560E from Broadcom Limited is the qualified substitute for the obsolete PS9114-F3-A. Selection is based on the following engineering factors:

Product Status Consideration: The PS9114-F3-A is classified as obsolete, creating supply chain risk. The HCPL-M611-560E maintains active production status, ensuring long-term availability and supply continuity.

Compliance and Certification: The HCPL-M611-560E is RoHS3 compliant and REACH unaffected, providing superior regulatory positioning compared to the original part's REACH affected status. Both parts share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications.

Electrical Performance: The substitute part meets or exceeds all critical electrical parameters. Isolation voltage increases from 2500Vrms to 3750Vrms, and output current capability doubles from 25 mA to 50 mA. These enhancements provide additional design margin without introducing incompatibility.

Functional Equivalence: Identical propagation delay specifications (75ns maximum for both tpLH and tpHL), matching data rate (10Mbps/10MBd), and identical CMTI (10kV/µs) ensure functional interchangeability in existing circuit designs.

Package Compatibility: Both parts utilize identical 6-SOIC surface mount packaging with 5-lead configuration, enabling direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-M611-560E be used as a direct replacement for PS9114-F3-A in existing designs?

A: Yes. The HCPL-M611-560E is electrically and mechanically compatible with the PS9114-F3-A. Identical propagation delays, data rates, CMTI specifications, supply voltage ranges, operating temperature ranges, and package configurations enable direct substitution without circuit redesign.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (CEL versus Broadcom Limited), product status (obsolete versus active), and enhanced electrical specifications in the substitute. The HCPL-M611-560E provides higher isolation voltage (3750Vrms versus 2500Vrms), greater output current (50 mA versus 25 mA), and includes Schottky clamping in the output stage. The substitute also offers superior regulatory compliance (RoHS3 compliant, REACH unaffected).

Q: Are there any timing considerations when substituting these parts?

A: No. Both parts specify identical maximum propagation delays (75ns for tpLH and tpHL). Rise time increases marginally in the substitute (24ns versus 20ns typical), which remains within acceptable operating margins for 10Mbps applications. Fall time remains identical at 10ns typical.

Q: Does the Schottky clamping in the HCPL-M611-560E affect circuit operation?

A: No. Schottky clamping in the output stage enhances performance by reducing output voltage overshoot and improving switching characteristics. This feature is transparent to the circuit and does not require design modifications.

Q: What is the impact of increased output current capability?

A: The HCPL-M611-560E provides 50 mA output current versus 25 mA in the original part. This enhancement increases design margin and allows driving higher capacitive loads or multiple parallel inputs without performance degradation. Existing circuits designed for 25 mA operation remain fully compatible.

Q: Are the packages truly identical?

A: Yes. Both parts use 6-SOIC surface mount packages with 0.173" width (4.40mm) and 5-lead configuration. PCB footprints are identical, and no layout modifications are required for substitution.

Q: What is the significance of the product status difference?

A: The PS9114-F3-A is obsolete, indicating discontinued manufacturing and limited remaining inventory. The HCPL-M611-560E is actively produced, ensuring reliable long-term availability for new designs and ongoing system support.
