Key Parameters

Substitute Part Grouping Explanation

Substitution criteria for the SMP-MSLD-PCS17T are based on the following allowed electrical and mechanical parameters: SMP connector style, Jack male pin configuration, 50 Ohm impedance, solder contact and shield termination, surface mount design with snap-on fastening, and single port count. Parts are considered compatible substitutes when they maintain these core specifications while potentially offering improvements in secondary parameters such as maximum frequency capability, operating temperature range, or product lifecycle status.

The identified substitutes are grouped into the following categories:

Similar Manufacturer Part (Amphenol RF): SMP-MSLD-PCS20T maintains all core electrical and mechanical parameters while offering enhanced frequency capability (20 GHz vs. 18 GHz) and Active product status.

Parametric Equivalent (Amphenol RF): SMP-MSLD-PCS-5T provides equivalent electrical performance with identical frequency and temperature ratings, sharing the same base product number as the main part.

Direct Manufacturer Part (Rosenberger): 19S101-40ML5 is a Rosenberger SMP connector with equivalent impedance and mounting specifications, providing cross-manufacturer compatibility for 50 Ohm coaxial applications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: SMP-MSLD-PCS20T is the recommended selection as the direct successor to SMP-MSLD-PCS17T. This part maintains all required electrical and mechanical parameters, provides enhanced frequency capability at 20 GHz, and carries Active product status. Both components are ROHS3 compliant with identical MSL ratings.

For Existing Applications: SMP-MSLD-PCS-5T serves as a direct parametric equivalent with identical frequency and temperature specifications. This part is available in equivalent Tape & Reel packaging and shares the same base product number, enabling seamless integration into existing designs.

For Cross-Manufacturer Substitution: 19S101-40ML5 from Rosenberger provides compatibility with the 50 Ohm SMP connector specification. Note that this component is a Plug configuration rather than Jack and is supplied in Bulk packaging. This part offers the highest frequency capability at 26.5 GHz and maintains RoHS compliance.

Product Lifecycle Consideration: Both SMP-MSLD-PCS20T and 19S101-40ML5 carry Active product status and are suitable for new product development. SMP-MSLD-PCS-5T retains the same "Not For New Designs" designation as the main part.

Frequently Asked Questions (FAQ)

Q: Can SMP-MSLD-PCS20T replace SMP-MSLD-PCS17T directly? A: SMP-MSLD-PCS20T is a direct substitute maintaining all core electrical and mechanical parameters. It provides the same solder contact and shield termination, surface mount design, and 50 Ohm impedance. The enhanced 20 GHz frequency capability represents an improvement over the 18 GHz specification of the main part.

Q: What is the difference between Jack and Plug connector types? A: Jack and Plug are complementary connector types. The main part SMP-MSLD-PCS17T is a Jack with male pin configuration. The Rosenberger 19S101-40ML5 is a Plug with male pin configuration. These types are mated together in RF coaxial applications and are not directly interchangeable within a single mechanical assembly position.

Q: Why does SMP-MSLD-PCS20T have a lower operating temperature range? A: The SMP-MSLD-PCS20T operates from -40°C to 85°C compared to -65°C to 165°C for the main part. Applications requiring the full -65°C to 165°C range should use SMP-MSLD-PCS-5T or 19S101-40ML5, which maintain the extended temperature specifications.

Q: What is the difference between PTFE and LCP dielectric materials? A: SMP-MSLD-PCS17T uses Polytetrafluoroethylene (PTFE) dielectric material, while the substitute parts employ Liquid Crystal Polymer (LCP). Both materials are suitable for high-frequency RF applications. The selection between them depends on specific application requirements for loss characteristics, impedance stability, and mechanical properties.

Q: Are there packaging considerations when selecting a substitute? A: SMP-MSLD-PCS17T and SMP-MSLD-PCS20T are supplied in Tape & Reel packaging suitable for automated assembly. SMP-MSLD-PCS-5T also uses Tape & Reel packaging. The Rosenberger 19S101-40ML5 is supplied in Bulk packaging and may require different handling procedures in manufacturing environments optimized for tape-reel component placement.

Q: Is cross-manufacturer substitution feasible with Rosenberger 19S101-40ML5? A: Cross-manufacturer substitution is feasible when the mechanical fit, electrical impedance, and connector interface standards are equivalent. The 19S101-40ML5 meets the 50 Ohm SMP connector standard and snap-on fastening requirement. However, the Plug vs. Jack distinction must be verified against the mating interface in your application.

Q: What are the implications of REACH and RoHS compliance? A: All substitute parts maintain either ROHS3 or RoHS compliance, confirming the absence of restricted substances. REACH compliance is confirmed for all parts, ensuring regulatory acceptance in applications subject to REACH requirements.
