Substitute Part Grouping Explanation

Substitution of the SMP-P-P-H-ST-EM3-PIN 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
• Number of Ports: 1
• Dielectric Material: Polytetrafluoroethylene (PTFE)

Acceptable Variations:

• Center Contact Material: Brass or Beryllium Copper
• Body Material: Brass or Beryllium Copper
• Operating Temperature range (when specified)
• Packaging format

The substitute part 91_SMP-50-0-L1/111_NE from Huber+Suhner Inc. meets all mandatory matching parameters and qualifies as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the SMP-P-P-H-ST-EM3-PIN and 91_SMP-50-0-L1/111_NE are active products with ROHS3 compliance and EAR99 export classification. Selection between these parts is based on the following criteria:

SMP-P-P-H-ST-EM3-PIN (Samtec Inc.):

• Primary choice when Samtec supply chain is preferred
• Brass construction with gold plating
• Higher current inventory availability (1128 pcs)

91_SMP-50-0-L1/111_NE (Huber+Suhner Inc.):

• Parametric equivalent with beryllium copper construction
• Specified operating temperature range of -55°C to 125°C
• Alternative sourcing option with 1017 pcs inventory

Both parts satisfy identical electrical and mechanical requirements for 50 Ohm SMP connector plug applications operating at frequencies up to 40 GHz with board edge cutout surface mount solder termination.

Frequently Asked Questions (FAQ)

Q: What makes 91_SMP-50-0-L1/111_NE a valid substitute for SMP-P-P-H-ST-EM3-PIN?

A: The substitute part matches all critical parameters: SMP connector style, male pin plug type, 50 Ohm impedance, board edge cutout mounting with surface mount solder termination, snap-on fastening, 40 GHz maximum frequency, single port configuration, and PTFE dielectric material. Both parts are ROHS3 compliant with EAR99 classification.

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

A: Yes. The SMP-P-P-H-ST-EM3-PIN uses brass for center contact and body material, while the 91_SMP-50-0-L1/111_NE uses beryllium copper. Both are gold-plated and functionally equivalent for the specified 50 Ohm RF application.

Q: Does the Huber+Suhner part include an operating temperature specification?

A: Yes. The 91_SMP-50-0-L1/111_NE specifies an operating temperature range of -55°C to 125°C. The Samtec part does not include this specification in the provided data.

Q: What is the packaging difference?

A: The Samtec part packaging is not specified in the provided data. The Huber+Suhner part is supplied in bulk packaging.

Q: Can these parts be used interchangeably in production?

A: Both parts meet identical electrical and mechanical specifications for 50 Ohm SMP connector plug applications. Interchangeability is determined by design requirements and qualification procedures specific to the end application.

Q: What inventory levels are available?

A: SMP-P-P-H-ST-EM3-PIN has 1128 pcs in stock. The 91_SMP-50-0-L1/111_NE has 1017 pcs in stock.
