Key Parameters

Substitute Part Grouping Explanation

Substitution for the MS-145-C(LP)-A is determined by strict equivalence across the following critical parameters:

• Connector style and physical dimensions (Coaxial Switch - 4.15mm Plug Dia)
• Electrical specifications (50 Ohm impedance, 2.5 GHz maximum frequency)
• Connector type and pin configuration (Plug, Male Pin)
• Termination method (Solder for both contact and shield)
• Mounting configuration (Free Hanging In-Line, Right Angle)
• Mechanical interface (Push-Pull fastening, 10000 mating cycles)
• Environmental operating range (-30°C ~ 85°C)
• Performance characteristics (0.6dB insertion loss)

The MS-145-C(LP)-1 qualifies as a direct substitute based on identical alignment across all these parameters. The primary distinction is product status: the substitute part is active and available, whereas the original part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The MS-145-C(LP)-1 is the direct substitute for the obsolete MS-145-C(LP)-A. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The substitute part offers the advantage of active product status, ensuring ongoing availability and supply chain continuity.

The MS-145-C(LP)-1 carries RoHS Compliance certification, providing additional regulatory alignment for applications subject to environmental standards. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications, indicating no change in export control or tariff considerations.

Selection of the MS-145-C(LP)-1 eliminates obsolescence risk while maintaining full functional and mechanical compatibility with existing designs utilizing the MS-145-C(LP)-A.
