Key Parameters

Substitute Part Grouping Explanation

The MS-162B qualifies as a parametric equivalent to the MS-162A based on the following critical substitution parameters:

• Identical connector style (Coaxial Switch - 4mm Plug Dia)
• Identical connector type (Receptacle, Female Socket)
• Identical impedance (50 Ohms)
• Identical maximum frequency (10 GHz)
• Identical mounting type (Surface Mount)
• Identical contact and shield termination (Solder)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical mating cycle rating (12000)
• Identical number of ports (1)
• Identical internal switch feature

The MS-162B represents an active product status replacement for the obsolete MS-162A, maintaining full electrical and mechanical compatibility within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

The MS-162B is the direct active equivalent for the obsolete MS-162A. Selection of MS-162B is appropriate for new designs and production continuity where MS-162A components are no longer available. The MS-162B maintains identical electrical performance specifications and mechanical compatibility. The MS-162B carries RoHS3 compliance certification, providing enhanced regulatory alignment for current manufacturing standards. Both parts share identical REACH and ECCN classifications, ensuring consistent supply chain and export compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can MS-162B be used as a direct replacement for MS-162A in existing assemblies?

A: Yes. The MS-162B is a parametric equivalent with identical connector style, impedance, frequency rating, mounting type, termination method, and operating temperature range. Mechanical and electrical compatibility is maintained.

Q: What is the primary difference between MS-162A and MS-162B?

A: The MS-162A is obsolete while MS-162B is active. The MS-162B also specifies insertion loss at 0.7dB and uses Liquid Crystal Polymer (LCP) dielectric material versus Polyamide (PA) nylon in the MS-162A. The MS-162B includes RoHS3 compliance certification.

Q: Are there any compliance or certification differences?

A: The MS-162B carries RoHS3 compliance, while the MS-162A does not specify RoHS status. Both parts maintain identical REACH Unaffected status, ECCN EAR99 classification, and HTSUS code 8536.69.4010.

Q: What is the mating cycle rating for these connectors?

A: Both MS-162A and MS-162B are rated for 12000 mating cycles, indicating equivalent mechanical durability and expected service life.

Q: Are the center contact materials equivalent?

A: The MS-162A uses Beryllium Copper while MS-162B uses Copper Alloy. Both materials are plated with gold and maintain the same electrical performance within the specified 50 Ohm impedance and 10 GHz frequency parameters.
