Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HRM-310(40) are identified based on strict parametric equivalence within the Hirose HRM series. The following criteria determine substitution validity:

Critical Matching Parameters:

• Connector Style: SMA
• Connector Type: Receptacle, Female Socket
• Impedance: 50 Ohms
• Mounting Type: Panel Mount, Right Angle
• Contact Termination: Solder
• Shield Termination: Solder
• Frequency - Max: 12.4 GHz
• Operating Temperature Range: -55°C ~ 125°C
• Mating Cycles: 1000

The HRM-305(40) and HRM-307(40) satisfy all critical parameters, establishing them as parametric equivalents within the HRM connector family. Differences exist only in base product designation, which reflects internal Hirose product line segmentation without affecting electrical or mechanical performance in the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

HRM-310(40) Status: Last Time Buy — production discontinuation confirmed. Immediate transition planning to substitute parts is required for ongoing procurement.

HRM-305(40) and HRM-307(40) Status: Both parts maintain Active product status with Hirose Electric Co Ltd, ensuring long-term availability and continued manufacturing support.

Compliance: All three parts carry RoHS Compliant certification and MSL Level 1 (Unlimited) moisture sensitivity rating, meeting regulatory requirements for commercial and industrial RF applications.

Selection Basis: HRM-305(40) and HRM-307(40) are direct parametric equivalents to HRM-310(40). Selection between these two substitute options should be based on inventory availability and lead time requirements. Both parts satisfy identical electrical and mechanical specifications for SMA 50 Ohm panel mount receptacle applications operating within the -55°C to 125°C temperature envelope.

Frequently Asked Questions (FAQ)

Q: Can HRM-305(40) and HRM-307(40) be used interchangeably with HRM-310(40)?

A: Yes. Both substitute parts match all critical electrical and mechanical parameters: SMA connector style, 50 Ohm impedance, receptacle female socket configuration, panel mount right angle mounting, solder termination, 12.4 GHz maximum frequency, and -55°C to 125°C operating temperature range. Physical dimensions, contact materials, and dielectric properties are identical.

Q: Why does the HRM-310(40) show Last Time Buy status?

A: Last Time Buy designation indicates Hirose Electric Co Ltd has discontinued production of this specific model number. HRM-305(40) and HRM-307(40) remain in active production and serve as the recommended long-term alternatives.

Q: Are there any differences in PCB footprint or mounting hole patterns between these parts?

A: The provided specifications do not include detailed dimensional or footprint data. Mechanical compatibility should be confirmed through Hirose technical documentation or direct comparison of engineering drawings for the specific application.

Q: Do all three parts carry the same certifications?

A: Yes. HRM-310(40), HRM-305(40), and HRM-307(40) all carry RoHS Compliant certification and MSL Level 1 (Unlimited) rating, meeting identical regulatory and environmental standards.

Q: What is the difference between HRM-305(40) and HRM-307(40)?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The difference in base product number reflects Hirose internal product line segmentation. Selection should be based on inventory availability and procurement lead times.
