Substitute Part Grouping Explanation

Substitution eligibility for the SMP-PL-P-HE-ST-EM3 is determined by strict equivalence across the following critical parameters:

• Connector Style: SMP
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Mounting Type: Board Edge, Cutout; Surface Mount
• Contact Termination: Solder
• Shield Termination: Solder
• Frequency - Max: 40 GHz
• Fastening Type: Snap-On
• Center Contact Material: Brass
• Body Material: Brass
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Voltage Rating: 335 V
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All three Molex substitute parts (0734153590, 0734153591, 0734153593) meet these core electrical and mechanical requirements. Differences in operating temperature maximum and mating cycles are noted in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

All three Molex substitute parts are active products with ROHS3 compliance and MSL 1 rating, matching the primary specification requirements of the SMP-PL-P-HE-ST-EM3.

The primary distinction between the main part and substitutes is the maximum operating temperature: the Samtec part supports -65°C to 165°C, while all Molex substitutes support -65°C to 155°C. Applications requiring operation above 155°C must use the original Samtec part.

For applications operating within the -65°C to 155°C range, all three Molex parts are electrically and mechanically equivalent. Selection among the three Molex options may be based on inventory availability, REACH compliance status, or procurement lead time.

Frequently Asked Questions (FAQ)

Q: Are the Molex parts (0734153590, 0734153591, 0734153593) fully interchangeable with the Samtec SMP-PL-P-HE-ST-EM3?

A: Yes, for applications operating within -65°C to 155°C. All parts share identical electrical characteristics (50 Ohm impedance, 40 GHz frequency rating, 335 V voltage rating), mechanical mounting (board edge, cutout, surface mount), and material composition (brass body and center contact, PTFE dielectric). The Samtec part supports a higher maximum operating temperature of 165°C.

Q: What is the difference between the three Molex substitute parts?

A: The three Molex parts (0734153590, 0734153591, 0734153593) are electrically and mechanically identical. The differences are in REACH compliance status: 0734153590 is REACH Affected, while 0734153591 and 0734153593 are REACH Unaffected. Selection depends on regulatory requirements for your application region.

Q: Can I use a Molex substitute if my application requires operation above 155°C?

A: No. The Molex substitutes are rated to -65°C ~ 155°C maximum, while the Samtec SMP-PL-P-HE-ST-EM3 is rated to -65°C ~ 165°C. For applications requiring operation above 155°C, the original Samtec part must be used.

Q: Are all parts RoHS3 compliant?

A: Yes. The Samtec SMP-PL-P-HE-ST-EM3 and all three Molex substitutes are ROHS3 compliant.

Q: What is the MSL rating for these connectors?

A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
