Procurement Notes

This component is a military-grade part identified by the 5962 prefix, indicating compliance with specific government standards. Procurement requires verification of authenticity through authorized distributors or direct manufacturer channels due to the specialized nature of hermetically sealed packages. Buyers must confirm the exact suffix KEC corresponds to the 16-DIP package variant. Quality assurance documentation, including test reports and material certifications, should be requested to ensure compliance with defense or aerospace specifications. Counterfeit prevention measures are essential when sourcing this specific part number.

Selection Notes

Engineers selecting this optocoupler should prioritize applications requiring high-speed digital isolation with strict timing constraints. The 10MBd speed rating makes it suitable for serial communication interfaces where rapid signal transfer is critical. The wide operating temperature range supports deployment in harsh industrial environments. Designers must account for the open-collector output configuration when designing pull-up resistor networks. The hermetic seal offers advantages over plastic-packaged alternatives in moisture-sensitive or radiation-exposed scenarios, though availability may be more limited compared to commercial variants.

Part Context

The 5962-0824203KEC belongs to the broader family of high-speed optocouplers manufactured by Broadcom Limited. This series includes various channel configurations and package options tailored for different isolation requirements. The 5962 designation signifies that the component meets federal procurement standards, distinguishing it from commercial equivalents like the ACPL-5962L series. These devices are engineered for demanding applications where reliability and signal integrity are paramount, serving as critical components in safety-critical systems across multiple industries.

Replacement Considerations

Direct replacements include the 5962-0824203KUC (surface mount variant) and the commercial equivalent ACPL-5962L. Verify pinout compatibility and package dimensions before substitution. Ensure the replacement maintains the required 1500VDC isolation rating and 10MBd speed specification. Hermetic sealing requirements must be confirmed if environmental protection is critical for the application.
