SMP-MSLD-PCS-5T Equivalent & Substitute Parts

Part Overview

The SMP-MSLD-PCS-5T is a coaxial connector (RF) manufactured by Amphenol RF, specifically an SMP Connector Jack with male pin configuration, 50 Ohms impedance, designed for surface mount solder termination. With a current product status of "Not For New Designs," alternative equivalent parts become necessary for ongoing production, system updates, or where design specifications allow parameter flexibility within acceptable ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SMP-MSLD-PCS-5T is determined by strict equivalence across electrical and mechanical parameters:

Critical Equivalence Parameters:

• Connector Style: SMP
• Connector Type: Jack, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Solder
• Mounting Type: Surface Mount
• Fastening Type: Snap-On
• Number of Ports: 1

Two equivalent parts meet these criteria with variations in frequency capability and operating temperature range:

SMP-MSLD-PCS20T: Direct functional equivalent with extended frequency rating (20 GHz vs. 18 GHz) and restricted operating temperature range (-40°C ~ 85°C vs. -65°C ~ 165°C). Active product status.

SMP-MSLD-PCS17T: Parametric equivalent with identical frequency rating (18 GHz) and operating temperature range (-65°C ~ 165°C). Not For New Designs status.

Engineering Selection Recommendations

SMP-MSLD-PCS20T is the preferred substitute for new component selection. This part maintains full electrical and mechanical equivalence while offering extended frequency capability (20 GHz) and carries active product status, ensuring ongoing manufacturer support and availability. Selection of SMP-MSLD-PCS20T is appropriate where system specifications do not require operation below -40°C or above 85°C.

SMP-MSLD-PCS17T provides parametric equivalence with identical frequency and temperature specifications to the original SMP-MSLD-PCS-5T. The dielectric material differs (PTFE vs. LCP), which may introduce performance considerations in specific RF applications. Like the original part, this substitute carries "Not For New Designs" status.

Selection between alternatives depends on operating temperature requirements and frequency capability needs of the application. Both substitutes maintain compliance certifications (ROHS3, REACH Affected, EAR99).

Frequently Asked Questions (FAQ)

Q: Can SMP-MSLD-PCS20T be used as a direct replacement for SMP-MSLD-PCS-5T? A: Yes, within the operating temperature range of -40°C to 85°C. Both parts share identical SMP connector style, 50 Ohm impedance, solder termination, and surface mount configuration. The SMP-MSLD-PCS20T provides identical electrical performance at frequencies up to 20 GHz.

Q: What is the key difference between SMP-MSLD-PCS20T and SMP-MSLD-PCS17T? A: SMP-MSLD-PCS20T extends the maximum frequency from 18 GHz to 20 GHz and restricts operating temperature to -40°C ~ 85°C. SMP-MSLD-PCS17T maintains the original -65°C ~ 165°C temperature range but retains the 18 GHz frequency limit. Additionally, SMP-MSLD-PCS17T uses PTFE dielectric material versus LCP in the other variants.

Q: Are there inventory considerations for these substitutes? A: Current inventory levels are: SMP-MSLD-PCS-5T (4,547 units), SMP-MSLD-PCS20T (5,072 units), and SMP-MSLD-PCS17T (1,899 units). Availability may influence procurement decisions for high-volume production.

Q: Do all three parts meet the same compliance requirements? A: Yes. All parts are ROHS3 Compliant, REACH Affected, and classified as EAR99. Packaging for all three is Tape & Reel (TR) format.

Q: Which substitute should be selected for extreme temperature applications? A: For applications requiring operation from -65°C to 165°C, SMP-MSLD-PCS17T maintains the original temperature specification. SMP-MSLD-PCS20T is limited to -40°C ~ 85°C and is unsuitable for extreme temperature environments.
