SMP-MSLD-PCS-T Equivalent & Substitute Parts

Part Overview

The SMP-MSLD-PCS-T is a coaxial connector manufactured by Amphenol RF, classified as an SMP-style jack with male pin configuration and 50-ohm impedance. This connector is designed for surface-mount applications operating up to 18 GHz with solder termination for both center contact and shield. The part is marked as "Not For New Designs," indicating it has reached end-of-life status. Finding suitable alternatives is necessary to support existing designs and procurement requirements where this connector must be replaced or sourced as inventory depletes.

Substitute Part Grouping Explanation

The SMP-MSLD-PCS20T qualifies as a substitute for the SMP-MSLD-PCS-T based on the following critical parameters that determine interchangeability:

Core Electrical Characteristics:

• Connector Style: SMP (identical)
• Connector Type: Jack, Male Pin (identical)
• Impedance: 50 Ohms (identical)
• Frequency - Max: 20 GHz (exceeds 18 GHz requirement)

Mechanical and Interface Requirements:

• Mounting Type: Surface Mount (identical)
• Contact Termination: Solder (identical)
• Shield Termination: Solder (identical)
• Fastening Type: Snap-On (identical)
• Mating Cycles: 500 (identical)

Compliance and Environmental:

• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)
• REACH Status: REACH Affected (identical)

Parameter Comparison

Engineering Selection Recommendations

The SMP-MSLD-PCS20T is an active product offering from Amphenol RF and is functionally compatible with the obsolete SMP-MSLD-PCS-T for applications within the overlapping temperature range of -40°C to 85°C. Both parts maintain ROHS3 compliance and identical MSL ratings, satisfying the same environmental and regulatory requirements. The substitute offers superior frequency performance at 20 GHz compared to the original 18 GHz specification, providing operational margin for RF applications. For designs operating below -40°C or above 85°C, the original SMP-MSLD-PCS-T operating range cannot be matched by this substitute, and alternative solutions must be evaluated.

Frequently Asked Questions (FAQ)

Q: Are the SMP-MSLD-PCS-T and SMP-MSLD-PCS20T pin-compatible? A: Both connectors share the SMP jack, male pin configuration with identical solder termination, snap-on fastening, and 50-ohm impedance. They are mechanically and electrically compatible within the specified operating parameters.

Q: What is the primary difference between these two parts? A: The main differences are product status (original is obsolete, substitute is active), maximum frequency (18 GHz vs. 20 GHz), and operating temperature range (-65°C ~ 165°C vs. -40°C ~ 85°C). The substitute has a narrower temperature range, which may impact suitability for extreme-temperature applications.

Q: Can I use the SMP-MSLD-PCS20T in applications requiring operation below -40°C? A: No. The SMP-MSLD-PCS20T is rated only to -40°C minimum. If your application requires operation below -40°C, this substitute is not suitable, and the original part or another alternative must be sourced.

Q: Is there any difference in packaging between these parts? A: Both parts are supplied in Tape & Reel (TR) packaging, making them suitable for automated pick-and-place assembly.

Q: Are both parts RoHS-compliant? A: Yes. Both the SMP-MSLD-PCS-T and SMP-MSLD-PCS20T are ROHS3 compliant with MSL Level 1 (Unlimited), meeting standard environmental and regulatory requirements.
