SMP-MSCM-PCS11T

Part Overview

The SMP-MSCM-PCS11T is an SMP Connector Jack with male pin configuration, rated at 50 Ohms impedance for surface mount applications. This connector is manufactured by Amphenol RF and is currently active in production. Alternative models become necessary when specific packaging requirements, frequency ratings, operating temperature ranges, or manufacturing source availability necessitate component substitution while maintaining functional compatibility and electrical performance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMP-MSCM-PCS11T must meet the following critical electrical and mechanical parameters:

• Connector Style: SMP (required for mating compatibility)
• Impedance: 50 Ohms (required for signal integrity)
• Contact Termination: Solder (required for assembly method compatibility)
• Shield Termination: Solder (required for assembly method compatibility)
• Mounting Type: Surface Mount (required for PCB assembly compatibility)
• Fastening Type: Snap-On (required for mechanical coupling)
• Number of Ports: 1 (required for single-port configuration)
• Dielectric Material: Liquid Crystal Polymer (LCP) (determines electrical performance)
• Material Composition: Brass with gold plating (determines contact reliability)

Acceptable variations between main and substitute parts may include: connector type configuration (Jack vs. Plug), frequency rating (if higher), maximum operating temperature, packaging format, and manufacturing source. These variations do not affect functional compatibility when the critical electrical and mechanical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

Both the SMP-MSCM-PCS11T and 19S144-40ML5 maintain active product status and meet RoHS and REACH compliance requirements. The Amphenol RF SMP-MSCM-PCS11T is supplied in Tape & Reel packaging and operates to 165°C maximum temperature. The Rosenberger 19S144-40ML5 is available in Bulk packaging and provides extended frequency capability (26.5 GHz vs. 18 GHz) with a maximum operating temperature of 155°C.

Selection between these connectors depends on application requirements for packaging format, operating temperature ceiling, and maximum frequency rating. Both connectors share identical 50 Ohm impedance, SMP connector style, surface mount configuration, and solder termination characteristics, ensuring functional interchangeability in standard RF applications within their respective rated parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can the 19S144-40ML5 directly replace the SMP-MSCM-PCS11T in all applications? A: Direct replacement is possible when the application frequency remains below 18 GHz and the maximum operating temperature requirement does not exceed 155°C. Both connectors share identical SMP connector style, 50 Ohm impedance, surface mount characteristics, and solder termination methods.

Q: What is the primary functional difference between these two connectors? A: The primary differences are connector type configuration (Jack vs. Plug), frequency rating (18 GHz vs. 26.5 GHz), maximum operating temperature (165°C vs. 155°C), and packaging format (Tape & Reel vs. Bulk). All other electrical and mechanical parameters remain identical.

Q: Are packaging format differences significant for component selection? A: Packaging format (Tape & Reel vs. Bulk) affects handling, storage, and assembly automation compatibility. This does not influence electrical or mechanical performance but impacts procurement and manufacturing processes.

Q: Do both connectors meet regulatory compliance requirements? A: Yes. Both connectors are RoHS and REACH compliant with Moisture Sensitivity Level 1 (Unlimited). The SMP-MSCM-PCS11T carries ROHS3 designation while the 19S144-40ML5 carries RoHS designation. Both hold EAR99 ECCN classification and 8536.69.4010 HTSUS codes.

Q: What determines whether a substitute connector is acceptable for a specific application? A: Substitution acceptability depends on matching the critical parameters: SMP connector style, 50 Ohm impedance, surface mount mounting type, snap-on fastening, solder termination, liquid crystal polymer dielectric, and single-port configuration. Operating temperature range, frequency rating, and packaging format must align with specific application requirements.
