916AH524 SMA Connector Plug Equivalent & Substitute Parts

Part Overview

The 916AH524 is an SMA connector plug manufactured by Winchester Interconnect, designed for RF coaxial applications requiring 50-ohm impedance. This male pin connector features solder termination for both contact and shield, panel mount configuration with threaded fastening, and operates across a frequency range up to 12.5 GHz. The connector is actively produced and RoHS compliant, making it suitable for modern electronic assemblies. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or application-specific performance needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 916AH524 is determined by strict equivalence across critical electrical and mechanical parameters. The following parameters must match or remain compatible:

Mandatory Matching Parameters:

• Connector Style: SMA
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Solder
• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Fastening Type: Threaded
• Number of Ports: 1
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Center Contact Plating: Gold

Allowable Parameter Variations: Substitute parts may differ in frequency maximum, operating temperature range, mating cycles, body material composition, and insertion loss specifications, provided the substitute meets or exceeds the application requirements and maintains RoHS compliance status.

The HRM-406S(40) from Hirose Electric Co Ltd qualifies as a substitute based on full alignment with all mandatory matching parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 916AH524 and HRM-406S(40) are active products with RoHS compliance certification, qualifying them for use in regulated applications. Selection between these parts is based on specific application requirements:

916AH524 Selection Criteria:

• Applications requiring extended operating temperature range (-65°C to 165°C)
• Designs with frequency requirements up to 12.5 GHz
• Brass body material preference for specific environmental conditions

HRM-406S(40) Selection Criteria:

• Applications with standard operating temperature range (-55°C to 125°C)
• Designs benefiting from extended mating cycle capability (1000 cycles versus 500)
• Stainless steel body material for enhanced corrosion resistance
• Specified insertion loss performance (0.1 dB) for signal integrity documentation
• Extended insulation feature for additional electrical isolation

Both connectors maintain identical electrical impedance, termination methods, and dielectric properties, ensuring functional interchangeability within their respective operating parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can the HRM-406S(40) be used as a direct replacement for the 916AH524 in all applications?

A: The HRM-406S(40) is electrically and mechanically compatible with the 916AH524 for applications operating within the temperature range of -55°C to 125°C and frequency requirements up to 12.4 GHz. Applications requiring the extended temperature range of the 916AH524 (-65°C to 165°C) or maximum frequency of 12.5 GHz require the original part.

Q: What is the significance of the different body materials (Brass versus Stainless Steel)?

A: The 916AH524 uses brass body material, while the HRM-406S(40) uses stainless steel. Stainless steel provides enhanced corrosion resistance in harsh environmental conditions. Brass offers different thermal and electrical characteristics. Material selection depends on the specific environmental exposure and thermal management requirements of the application.

Q: Why does the HRM-406S(40) have a higher mating cycle rating?

A: The HRM-406S(40) is rated for 1000 mating cycles compared to the 916AH524's 500 cycles. This indicates the Hirose connector is designed for applications with more frequent connection and disconnection cycles. For applications with limited mating cycle requirements, both parts are suitable.

Q: Are both connectors suitable for RoHS-regulated applications?

A: Yes, both the 916AH524 and HRM-406S(40) are RoHS compliant and suitable for applications subject to RoHS regulations.

Q: What does the insertion loss specification of 0.1 dB for the HRM-406S(40) mean?

A: Insertion loss of 0.1 dB indicates the signal attenuation introduced by the connector at RF frequencies. This specification is provided for the HRM-406S(40) but not specified for the 916AH524. For applications requiring documented insertion loss performance, the HRM-406S(40) provides this technical data.

Q: How do the frequency specifications differ between these connectors?

A: The 916AH524 operates up to 12.5 GHz, while the HRM-406S(40) operates up to 12.4 GHz. Both are suitable for applications within these frequency ranges. The 0.1 GHz difference is negligible for most RF applications operating below 12.4 GHz.

Q: What is the significance of the Extended Insulation feature on the HRM-406S(40)?

A: Extended insulation on the HRM-406S(40) provides additional electrical isolation between the center contact and shield. This feature enhances electrical safety and signal integrity in applications requiring additional isolation margins.
