Substitute Part Grouping Explanation

Substitute parts for the SMPM-PF-P-EE-ST-SM-3 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Connector Style: SMPM
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Mounting Type: Surface Mount
• Contact Termination: Solder
• Shield Termination: Solder
• Fastening Type: Snap-On
• Frequency - Max: 65 GHz
• Number of Ports: 1
• Features: Full Detent
• RoHS Status: ROHS3 Compliant
• Product Status: Active

All identified substitute parts maintain these core electrical and mechanical specifications, ensuring direct functional equivalence in RF applications. Variations in body material composition and dielectric material do not affect substitution eligibility when all critical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SMPM-PF-P-EE-ST-SM-3, SMPM-PF-P-EE-ST-SM-2, and SMPM-PF-P-EG-ST-SM-1—are Active status products manufactured by Samtec Inc. and maintain full ROHS3 compliance. Selection among these equivalents is based on inventory availability and packaging requirements rather than electrical or mechanical performance differences.

SMPM-PF-P-EE-ST-SM-3 and SMPM-PF-P-EE-ST-SM-2 are parametrically identical across all specified electrical and mechanical characteristics. SMPM-PF-P-EG-ST-SM-1 differs in body material composition (Beryllium Copper versus Brass) and dielectric material (PTFE versus PEEK), with an operating temperature range of -65°C to 125°C specified. These material variations do not affect RF performance or substitution eligibility when all critical connector parameters remain constant.

Frequently Asked Questions (FAQ)

Q: Can SMPM-PF-P-EE-ST-SM-2 be used as a direct replacement for SMPM-PF-P-EE-ST-SM-3?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including impedance, frequency range, mounting type, and termination method. Substitution is direct.

Q: What is the difference between SMPM-PF-P-EG-ST-SM-1 and the other two parts?

A: SMPM-PF-P-EG-ST-SM-1 differs in body material (Beryllium Copper instead of Brass) and dielectric material (PTFE instead of PEEK). It also specifies an operating temperature range of -65°C to 125°C. These material differences do not affect RF performance or connector compatibility when all critical parameters match.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three parts—SMPM-PF-P-EE-ST-SM-3, SMPM-PF-P-EE-ST-SM-2, and SMPM-PF-P-EG-ST-SM-1—are ROHS3 compliant and classified as Active products.

Q: What is the packaging difference between these parts?

A: SMPM-PF-P-EE-ST-SM-3 and SMPM-PF-P-EE-ST-SM-2 have no specified packaging designation. SMPM-PF-P-EG-ST-SM-1 is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical performance.

Q: Can these connectors be used interchangeably in 50 Ohm RF applications?

A: Yes. All three parts maintain 50 Ohm impedance and operate at frequencies up to 65 GHz. They are mechanically and electrically interchangeable for applications requiring SMPM plug connectors with solder termination and snap-on fastening.

Q: What is the maximum frequency rating for these connectors?

A: All three parts are rated for frequencies up to 65 GHz, making them suitable for high-frequency RF applications.
