916AF524 SMA Connector Plug Equivalent & Substitute Parts

Part Overview

The 916AF524 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 center contact and shield, with panel mount configuration using a threaded fastening mechanism. The component operates across a temperature range of -65°C to 165°C and supports frequencies up to 12.5 GHz.

The product maintains Active status with 1089 units in current inventory. Substitute parts are identified for applications where component availability, specific performance characteristics, or supply chain requirements necessitate alternative sourcing options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 916AF524 is determined by strict equivalence across the following critical parameters:

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

Allowable Variation Parameters:

• Frequency Maximum: Within operational bandwidth requirements
• Operating Temperature Range: Must encompass application minimum and maximum requirements
• Mating Cycles: Rated value must meet or exceed application duty cycle
• Body Material and Finish: Variation permitted if electrical and mechanical performance maintained
• Insertion Loss: Specification provided where applicable

The substitute part HRM-402S(40) from Hirose Electric Co Ltd satisfies all mandatory matching parameters and is therefore classified as an equivalent substitute.

Engineering Selection Recommendations

916AF524 (Winchester Interconnect) - Primary Selection:

• Product Status: Active with established supply (1089 units in stock)
• Operating Temperature Range: -65°C to 165°C provides extended low-temperature capability
• Frequency Performance: 12.5 GHz maximum frequency
• Mating Cycle Rating: 500 cycles
• Compliance: RoHS Compliant, MSL 1

HRM-402S(40) (Hirose Electric Co Ltd) - Substitute Selection:

• Product Status: Last Time Buy (limited future availability)
• Operating Temperature Range: -55°C to 125°C (narrower than primary part)
• Frequency Performance: 12.4 GHz maximum frequency (0.1 GHz lower than primary)
• Mating Cycle Rating: 1000 cycles (higher durability rating)
• Compliance: RoHS Compliant, MSL 1
• Additional Feature: Extended Insulation
• Insertion Loss: 0.1 dB specified

Selection between these parts depends on application-specific requirements. The 916AF524 is recommended for applications requiring extended temperature operation below -55°C or above 125°C. The HRM-402S(40) is suitable for applications within the -55°C to 125°C range and offers higher mating cycle capability. Both parts meet 50-ohm impedance, solder termination, and panel mount flange requirements.

Frequently Asked Questions (FAQ)

Q: Can HRM-402S(40) replace 916AF524 in all applications?

A: Substitution is valid only when the application operating temperature range falls within -55°C to 125°C and the maximum frequency requirement does not exceed 12.4 GHz. Applications requiring operation below -55°C or above 125°C require the 916AF524.

Q: What is the difference in body material between these connectors?

A: The 916AF524 uses brass body material, while the HRM-402S(40) uses stainless steel body material. Both materials are compatible with the solder termination process and maintain 50-ohm impedance performance.

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

A: The HRM-402S(40) is rated for 1000 mating cycles compared to 500 cycles for the 916AF524. This specification reflects the mechanical durability of the connector design and does not affect electrical performance in applications requiring fewer cycles.

Q: Are both parts RoHS compliant?

A: Yes, both the 916AF524 and HRM-402S(40) are RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited).

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

A: Last Time Buy status indicates that Hirose Electric Co Ltd has announced limited future production of this part. Current inventory is available, but long-term supply cannot be guaranteed. For applications requiring sustained component availability, the 916AF524 with Active status is the recommended choice.

Q: Is insertion loss a critical parameter for selection?

A: Insertion loss of 0.1 dB is specified for HRM-402S(40) but not provided for 916AF524. Both connectors are suitable for RF applications up to their respective frequency maximums. Insertion loss becomes critical only in high-frequency, low-noise applications where signal attenuation must be minimized.
