Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HRM-302(09) is determined by strict equivalence across the following critical parameters: Connector Style (SMA), Connector Type (Receptacle, Female Socket), Impedance (50 Ohms), Contact Termination (Solder), Shield Termination (Solder), Mounting Type (Panel Mount), Mounting Feature (Flange), Fastening Type (Threaded), Frequency - Max (12.4 GHz), Number of Ports (1), Center Contact Material (Beryllium Copper), and Dielectric Material (PTFE).

The substitute parts are grouped into two categories:

Hirose Electric Co Ltd Series (HRM-303(09) and HRM-306(09)): These parts maintain identical electrical and mechanical specifications to the HRM-302(09), including body material (Stainless Steel), operating temperature range (-55°C ~ 85°C), mating cycles (1000), and insertion loss (0.1 dB). All three Hirose parts are RoHS Compliant with MSL 1 rating.

Amphenol RF Series (132146 and 132147): These parts match all critical electrical parameters and mounting specifications. Differences exist in body material (Brass instead of Stainless Steel), operating temperature range (-65°C ~ 165°C), mating cycles (500), and compliance certifications (ROHS3 Compliant with REACH Affected status). Insertion loss data is not provided for these parts.

Parameter Comparison

Engineering Selection Recommendations

Hirose Electric Co Ltd Parts (HRM-303(09) and HRM-306(09)): These parts are direct parametric equivalents to the HRM-302(09) with identical electrical performance, mechanical specifications, and compliance certifications. Selection between HRM-302(09), HRM-303(09), and HRM-306(09) is based on inventory availability and procurement lead times. All three maintain RoHS Compliance and MSL 1 rating. HRM-306(09) offers the highest current inventory level at 1121 units.

Amphenol RF Parts (132146 and 132147): These parts satisfy all critical electrical and mechanical requirements for SMA 50 Ohm panel mount solder connectors. The extended operating temperature range (-65°C ~ 165°C) provides broader thermal capability compared to the HRM series (-55°C ~ 85°C). However, mating cycle rating is reduced to 500 cycles versus 1000 cycles for Hirose parts. Insertion loss data is not provided for these parts. Both Amphenol RF parts carry ROHS3 Compliance and REACH Affected status. Selection of Amphenol RF parts is appropriate when extended temperature operation is required or when Hirose inventory is unavailable. Part 132147 provides the highest inventory availability at 3041 units.

Frequently Asked Questions (FAQ)

Q: Can HRM-303(09) and HRM-306(09) be used interchangeably with HRM-302(09)?

A: Yes. HRM-303(09) and HRM-306(09) are parametric equivalents with identical electrical specifications, mechanical mounting, impedance, frequency rating, operating temperature range, mating cycles, and insertion loss. All three parts are manufactured by Hirose Electric Co Ltd and carry identical RoHS Compliance and MSL ratings. Selection is based on inventory availability.

Q: What are the key differences between Hirose and Amphenol RF substitute parts?

A: Hirose parts (HRM-302(09), HRM-303(09), HRM-306(09)) use Stainless Steel bodies with operating temperature range -55°C ~ 85°C and 1000 mating cycles. Amphenol RF parts (132146, 132147) use Brass bodies with extended operating temperature range -65°C ~ 165°C but reduced mating cycles of 500. Insertion loss is specified as 0.1 dB for Hirose parts; Amphenol RF insertion loss data is not provided. Compliance differs: Hirose parts are RoHS Compliant; Amphenol RF parts are ROHS3 Compliant with REACH Affected status.

Q: Are the Amphenol RF parts suitable for high-temperature applications?

A: Amphenol RF parts 132146 and 132147 support operating temperatures up to 165°C, compared to 85°C maximum for Hirose parts. This extended thermal range makes Amphenol RF parts suitable for applications requiring higher temperature operation. However, mating cycle rating is 500 cycles versus 1000 cycles for Hirose parts.

Q: What packaging differences exist between substitute parts?

A: Hirose Electric Co Ltd parts (HRM-302(09), HRM-303(09), HRM-306(09)) are supplied in Bulk packaging. Amphenol RF parts (132146, 132147) are supplied in Bag packaging. Packaging selection may affect handling, storage, and integration into assembly processes.

Q: Which substitute part offers the best inventory availability?

A: Amphenol RF part 132147 provides the highest inventory level at 3041 units in stock, followed by 132146 at 2307 units. Among Hirose parts, HRM-306(09) offers 1121 units, HRM-303(09) offers 738 units, and HRM-302(09) offers 720 units.

Q: Can I substitute Amphenol RF parts in designs originally specified for Hirose parts?

A: Amphenol RF parts 132146 and 132147 meet all critical electrical and mechanical parameters for SMA 50 Ohm panel mount solder connectors. Substitution is valid when the extended operating temperature range (-65°C ~ 165°C) and reduced mating cycle rating (500 cycles) are compatible with application requirements. Compliance certifications differ; verify ROHS3 and REACH requirements for your application.
