916AS524 SMA Connector Plug Equivalent & Substitute Parts

Part Overview

The 916AS524 is an SMA connector plug manufactured by Winchester Interconnect, designed for 50-ohm RF applications requiring panel mount solder termination. This component operates across a frequency range up to 12.5 GHz and maintains performance across an operating temperature range of -65°C to 165°C. The part is currently in Active product status with 661 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 916AS524 is determined by strict alignment of the following critical parameters:

Electrical Parameters: Connector style (SMA), connector type (Plug, Male Pin), impedance (50 Ohms), and maximum frequency capability must match or exceed the original specification.

Termination Parameters: Both contact termination and shield termination must be solder-based to ensure compatibility with existing PCB assembly processes.

Mechanical Parameters: Mounting type (Panel Mount), mounting feature (Flange), and fastening type (Threaded) must be identical to maintain mechanical interchangeability.

Material & Environmental Parameters: Center contact plating (Gold), dielectric material (PTFE), and RoHS compliance status must align with the original design requirements.

The substitute part HRM-402S(40) from Hirose Electric Co Ltd meets all critical electrical and mechanical parameters required for direct substitution in the 916AS524 application.

Parameter Comparison

Engineering Selection Recommendations

916AS524 (Winchester Interconnect): This part maintains Active product status with current inventory availability of 661 units. It provides the widest operating temperature range (-65°C to 165°C) and maximum frequency specification of 12.5 GHz. Selection is appropriate for applications requiring extended temperature performance or maximum frequency headroom.

HRM-402S(40) (Hirose Electric Co Ltd): This substitute part carries Last Time Buy status, indicating limited future availability. It provides superior mating cycle rating (1000 cycles versus 500 cycles) and includes extended insulation features. The operating temperature range (-55°C to 125°C) and maximum frequency (12.4 GHz) are suitable for standard industrial and commercial RF applications. Current inventory of 963 units supports immediate availability.

Both parts maintain RoHS compliance and identical electrical impedance, termination methods, and mechanical mounting configurations. Selection between these parts should be based on application temperature requirements, expected connector mating cycles, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can HRM-402S(40) directly replace 916AS524 in all applications?

A: Direct mechanical and electrical substitution is supported for applications operating within the HRM-402S(40) temperature range of -55°C to 125°C. Applications requiring operation below -55°C or above 125°C must use the 916AS524 due to its extended operating temperature range of -65°C to 165°C.

Q: What is the significance of the frequency difference (12.5 GHz vs 12.4 GHz)?

A: Both parts operate within standard SMA connector frequency specifications. The 0.1 GHz difference is negligible for typical RF applications. Applications with frequency requirements at or above 12.4 GHz are compatible with both parts.

Q: Why does HRM-402S(40) have higher mating cycle rating?

A: The HRM-402S(40) specifies 1000 mating cycles compared to 500 cycles for the 916AS524. This parameter reflects mechanical durability under repeated connection and disconnection. Applications requiring frequent connector engagement should prioritize the higher mating cycle rating.

Q: Are there packaging differences between these parts?

A: The 916AS524 packaging is not specified in available data. The HRM-402S(40) is supplied in Bulk packaging. Confirm packaging requirements with your procurement process before finalizing part selection.

Q: What does "Last Time Buy" status mean for HRM-402S(40)?

A: Last Time Buy indicates that Hirose Electric Co Ltd has announced limited future production of this part. Current inventory of 963 units represents available stock. Long-term applications should consider the 916AS524 for sustained supply chain support.

Q: Are both parts RoHS compliant?

A: Yes, both the 916AS524 and HRM-402S(40) are RoHS compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.
