Engineering Selection Recommendations

SMP-PL-P-GF-ST-TH2 (Samtec Inc.)

This substitute maintains identical electrical and mechanical specifications to the primary part. Both components share the same base product number (SMP-PL), manufacturer, and all critical RF parameters including 50 Ohm impedance, 40 GHz frequency capability, and PTFE dielectric material. Operating temperature range, voltage rating, and material composition are equivalent. ROHS3 compliance is maintained. This part is suitable for direct substitution in applications where the original SMP-PL-P-HG-ST-TH2 is specified.

CONSMP001-2-G (TE Connectivity Linx)

This substitute meets all primary equivalence criteria for SMP plug connector functionality at 50 Ohms and 40 GHz. Material composition differs, utilizing Beryllium Copper for body and center contact instead of Brass, with Polyamide-Imide (PAI) dielectric instead of PTFE. Operating temperature maximum is reduced to 155°C compared to 165°C. Voltage rating is elevated to 500 V. Mating cycle specification of 100 cycles is provided. ROHS3 compliance is confirmed. Selection of this part requires verification that the reduced maximum operating temperature and alternative dielectric material are compatible with the application environment and RF performance requirements.

Frequently Asked Questions (FAQ)

Q: Can SMP-PL-P-GF-ST-TH2 be used as a direct replacement for SMP-PL-P-HG-ST-TH2?

A: Yes. Both parts are SMP plug connectors with identical 50 Ohm impedance, 40 GHz frequency rating, through-hole solder mounting, and PTFE dielectric material. Electrical and mechanical parameters are equivalent, supporting direct substitution.

Q: What are the key differences between SMP-PL-P-HG-ST-TH2 and CONSMP001-2-G?

A: The primary differences are material composition and operating temperature range. CONSMP001-2-G uses Beryllium Copper body and center contact with PAI dielectric, compared to Brass with PTFE in the original part. Maximum operating temperature is 155°C versus 165°C. Voltage rating is higher at 500 V. RF performance at 50 Ohms and 40 GHz remains equivalent.

Q: Is CONSMP001-2-G suitable for applications requiring 165°C operation?

A: No. CONSMP001-2-G is rated to 155°C maximum. Applications requiring operation at 165°C must use SMP-PL-P-HG-ST-TH2 or SMP-PL-P-GF-ST-TH2.

Q: Are all three parts ROHS3 compliant?

A: Yes. SMP-PL-P-HG-ST-TH2, SMP-PL-P-GF-ST-TH2, and CONSMP001-2-G are all ROHS3 compliant.

Q: What does the SMP connector style indicate?

A: SMP designates the SubMiniature Push-on connector style, a standardized RF connector format used in high-frequency applications up to 40 GHz with snap-on fastening and 50 Ohm impedance.

Q: Can these connectors be used interchangeably in PCB through-hole applications?

A: Yes, all three parts support through-hole solder mounting on printed circuit boards. Physical footprint compatibility should be verified during design integration.
