Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMP-MSSB-PSR-NM is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: SMP
• Connector Type: Jack, Male Pin
• Impedance: 50 Ohms
• Mounting Type: Surface Mount
• Contact Termination: Solder
• Shield Termination: Solder
• Frequency - Max: 20 GHz
• Number of Ports: 1
• Fastening Type: Snap-On
• Dielectric Material: Liquid Crystal Polymer (LCP)
• Body Finish: Gold
• Center Contact Plating: Gold
• Packaging: Tape & Reel (TR)
• RoHS Status: ROHS3 Compliant

The substitute part SMP-MSSB-PCS17T meets all mandatory matching parameters. Differences in center contact material (Beryllium Copper vs. Brass), body material (Beryllium Copper vs. Brass), and operating temperature range do not preclude substitution when the application requirements fall within the substitute part's specified operating window.

Parameter Comparison

Engineering Selection Recommendations

SMP-MSSB-PSR-NM (Primary Part)

Use this part when:

• Extended operating temperature range of -65°C to 165°C is required
• Non-magnetic properties are specified in design requirements
• Beryllium Copper contact material is mandated by application specifications
• Full temperature performance envelope must be maintained

SMP-MSSB-PCS17T (Substitute Part)

Use this part when:

• Operating temperature requirements fall within -40°C to 85°C range
• Brass contact material is acceptable for the application
• Supply availability of the primary part is constrained
• Both parts are ROHS3 Compliant and Active in product status
• Mechanical and electrical interface requirements are identical

Both parts share identical RF performance characteristics, impedance, frequency rating, and connector geometry. Selection between these parts is determined by operating temperature requirements and material specifications of the end application.

Frequently Asked Questions (FAQ)

Q: Can SMP-MSSB-PCS17T be used as a direct replacement for SMP-MSSB-PSR-NM in all applications?

A: Direct replacement is valid only when the application operating temperature remains within -40°C to 85°C. If the design requires operation below -40°C or above 85°C, the SMP-MSSB-PSR-NM must be used. All other electrical and mechanical parameters are equivalent.

Q: What is the difference between Beryllium Copper and Brass contact materials in these connectors?

A: Both materials are used in RF connector construction. The SMP-MSSB-PSR-NM uses Beryllium Copper for center contact and body material, while SMP-MSSB-PCS17T uses Brass. Material selection affects mechanical properties and temperature performance but does not alter the 50 Ohm impedance or 20 GHz frequency rating.

Q: Are both parts available in the same packaging format?

A: Yes. Both SMP-MSSB-PSR-NM and SMP-MSSB-PCS17T are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: What does "Smooth Bore" feature indicate?

A: Smooth Bore refers to the internal geometry of the connector jack. Both parts include this feature, which affects the mechanical fit and electrical performance of the mating interface.

Q: Are there any compliance differences between these two parts?

A: Both parts are ROHS3 Compliant and carry Active product status. The SMP-MSSB-PCS17T includes additional REACH Affected designation and MSL 1 (Unlimited) rating, while the SMP-MSSB-PSR-NM lists MSL as Not Applicable.

Q: What is the mating cycle rating for both connectors?

A: Both parts are rated for 1000 mating cycles, indicating equivalent mechanical durability for connector engagement and disengagement operations.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, provided the application temperature range permits use of the substitute part. The surface mount footprint, solder termination method, and snap-on fastening mechanism are identical between both parts.
