Substitute Part Grouping Explanation

Substitution of the SMP-P-P-ST-EM3-INS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: SMP
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Mounting Type: Board Edge, Cutout with Surface Mount capability
• Contact Termination: Solder
• Shield Termination: Solder
• Fastening Type: Snap-On
• Frequency - Max: 40 GHz minimum
• Number of Ports: 1
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Body Finish: Gold
• Center Contact Plating: Gold

The substitute part 91_SMP-50-0-L1/111_NE from Huber+Suhner Inc. meets all mandatory matching parameters. Variations in center contact material (Beryllium Copper versus Brass) and body material do not affect functional equivalence within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the SMP-P-P-ST-EM3-INS and 91_SMP-50-0-L1/111_NE are active production parts with ROHS3 compliance and identical export classification (EAR99). Selection between these parts should be based on:

Availability and Lead Time: The substitute part 91_SMP-50-0-L1/111_NE currently has 1017 pieces in stock compared to 990 pieces for the primary part, providing equivalent supply assurance.

Regulatory Compliance: Both parts satisfy ROHS3 requirements and carry identical HTSUS classification, ensuring compliance with environmental and trade regulations.

Operational Equivalence: The parts are electrically and mechanically interchangeable within the specified 50 Ohm, 40 GHz operating envelope. Material composition differences (Beryllium Copper versus Brass) do not affect performance within the provided parameter specifications.

Frequently Asked Questions (FAQ)

Q: Can the 91_SMP-50-0-L1/111_NE be used as a direct replacement for the SMP-P-P-ST-EM3-INS?

A: Yes. Both connectors meet identical specifications for impedance (50 Ohms), frequency response (40 GHz maximum), mounting configuration (board edge cutout with surface mount), termination method (solder), and fastening type (snap-on). They are functionally equivalent within the defined electrical and mechanical parameters.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching: connector style (SMP), connector type (plug, male pin), impedance (50 Ohms), mounting type (board edge cutout, surface mount), contact and shield termination (solder), fastening type (snap-on), maximum frequency (40 GHz), dielectric material (PTFE), and finish specifications (gold body and center contact plating).

Q: Are there differences in material composition between these parts?

A: The SMP-P-P-ST-EM3-INS uses brass for the center contact and body, while the 91_SMP-50-0-L1/111_NE uses beryllium copper. Both materials are plated with gold and perform equivalently within the specified 50 Ohm, 40 GHz operating parameters.

Q: Do both parts have the same environmental compliance?

A: Yes. Both parts are ROHS3 compliant and carry EAR99 export classification. The 91_SMP-50-0-L1/111_NE additionally specifies an operating temperature range of -55°C to 125°C and REACH unaffected status.

Q: What packaging formats are available?

A: The SMP-P-P-ST-EM3-INS is supplied in standard packaging. The 91_SMP-50-0-L1/111_NE is supplied in bulk packaging, which may affect procurement and handling procedures.
