HRM-310S(40) SMA Coaxial Connector Receptacle Equivalent & Substitute Parts

Part Overview

The HRM-310S(40) is an SMA connector receptacle manufactured by Hirose Electric Co Ltd, designed for RF coaxial applications requiring 50-ohm impedance. This female socket connector features right-angle panel mount configuration with solder termination for both center contact and shield. The part is currently in Active product status with 1002 units in stock.

Equivalent substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design flexibility allows for interchangeable components meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for HRM-310S(40) is determined by strict parametric equivalence across all critical electrical and mechanical specifications. The following parameters establish substitution validity:

Electrical Parameters: Connector style (SMA), impedance (50 Ohms), frequency maximum (12.4 GHz), insertion loss (0.1 dB), and operating temperature range (-55°C to 125°C) must be identical.

Mechanical Parameters: Connector type (Receptacle, Female Socket), mounting type (Panel Mount, Right Angle), contact termination (Solder), shield termination (Solder), fastening type (Threaded), and mounting feature (Flange) must match exactly.

Material Specifications: Center contact material (Beryllium Copper), center contact plating (Gold), body material (Stainless Steel), and dielectric material (PTFE) must be identical.

Performance Specifications: Mating cycles (1000) and number of ports (1) must be equivalent.

HRM-305S(40) and HRM-307S(40) meet all substitution criteria as parametric equivalents to HRM-310S(40).

Parameter Comparison

Engineering Selection Recommendations

All three parts—HRM-310S(40), HRM-305S(40), and HRM-307S(40)—are parametrically equivalent and electrically interchangeable for applications requiring SMA female receptacle connectors with 50-ohm impedance and right-angle panel mount configuration.

HRM-310S(40): Active product status with 1002 units in stock. RoHS Compliant. Recommended for new designs and ongoing production requiring long-term availability.

HRM-305S(40): Last Time Buy product status with 1036 units in stock. ROHS3 Compliant with REACH Affected designation. Suitable for applications where existing inventory must be consumed before transition to alternative parts. Not recommended for new designs due to end-of-life status.

HRM-307S(40): Active product status with 977 units in stock. RoHS Compliant. Suitable for new designs and production applications as a direct substitute when HRM-310S(40) availability is constrained.

Selection between HRM-310S(40) and HRM-307S(40) for new applications is based on inventory availability and supply chain considerations, as both maintain Active status and identical electrical-mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can HRM-305S(40), HRM-307S(40), and HRM-310S(40) be used interchangeably in the same circuit?

A: Yes. All three parts are parametrically equivalent across electrical specifications (50-ohm impedance, 12.4 GHz maximum frequency, 0.1 dB insertion loss), mechanical configuration (SMA female receptacle, right-angle panel mount, solder termination), and material composition (beryllium copper center contact with gold plating, stainless steel body, PTFE dielectric). Direct substitution is valid without circuit redesign.

Q: What is the difference between HRM-310S(40) and HRM-305S(40)?

A: The primary difference is product lifecycle status. HRM-310S(40) is Active, while HRM-305S(40) is Last Time Buy. Both parts are electrically and mechanically identical. HRM-305S(40) carries ROHS3 Compliant and REACH Affected designations, whereas HRM-310S(40) is RoHS Compliant. HRM-305S(40) should be used only to deplete existing inventory; new designs should specify HRM-310S(40) or HRM-307S(40).

Q: Are there any compliance differences between these parts?

A: HRM-310S(40) and HRM-307S(40) are both RoHS Compliant with MSL 1 (Unlimited). HRM-305S(40) is ROHS3 Compliant and REACH Affected. All three parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications. For applications requiring specific compliance certifications, verify requirements against individual part documentation.

Q: What is the operating temperature range for these connectors?

A: All three parts operate across -55°C to 125°C. This range is suitable for industrial, commercial, and military-grade RF applications within specified temperature limits.

Q: How many mating cycles are rated for these connectors?

A: All three parts are rated for 1000 mating cycles, indicating mechanical durability for applications requiring repeated connection and disconnection cycles.

Q: What packaging format is available?

A: All three parts are supplied in Bulk packaging format.
