Physical Finish Variation:

The substitute part features gold body finish and gold housing color compared to the nickel finish and silver housing of the original part. These finish variations do not affect electrical performance or mechanical compatibility and are cosmetic in nature.

Inventory Availability:

The Pomona Electronics 72954 maintains higher current inventory (1279 pcs) compared to the TE Connectivity AMP 5447648-3 (1087 pcs), supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the Pomona Electronics 72954 be used as a direct replacement for the TE Connectivity AMP 5447648-3 in existing designs?

A: Yes. The Pomona Electronics 72954 meets all mandatory electrical and mechanical specifications of the TE Connectivity AMP 5447648-3, including SMA connector style, 50-ohm impedance, free-hanging in-line mounting, cable group compatibility (RG-174, RG-188, RG-316), and 12.4 GHz frequency rating. Physical finish differences (gold versus nickel/silver) do not affect functional performance.

Q: What is the significance of the contact termination difference between the two parts?

A: The TE Connectivity AMP 5447648-3 specifies crimp termination only, while the Pomona Electronics 72954 supports both crimp and solder termination. This difference expands assembly options for the substitute part without introducing incompatibility. Designs utilizing crimp termination with the original part remain fully compatible with the substitute part using identical crimp termination methods.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are RoHS compliant. The TE Connectivity AMP 5447648-3 carries RoHS Compliant status, while the Pomona Electronics 72954 carries ROHS3 Compliant status, representing current compliance standards. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications. The Pomona part is REACH Unaffected, while the TE part is REACH Affected; however, this does not prevent substitution in applications where the original part was acceptable.

Q: What is the impact of the product status difference (Obsolete versus Active)?

A: The TE Connectivity AMP 5447648-3 is classified as Obsolete, indicating discontinued manufacturing and limited future availability. The Pomona Electronics 72954 maintains Active status, ensuring continued manufacturing and supply chain availability. For new designs or long-term production requirements, the Active status of the substitute part provides superior procurement reliability.

Q: Are the mating cycle ratings equivalent between these parts?

A: Yes. Both the TE Connectivity AMP 5447648-3 and Pomona Electronics 72954 are rated for 500 mating cycles, indicating identical mechanical durability and connector lifespan expectations.

Q: Does the cable group compatibility remain the same for the substitute part?

A: Yes. Both parts support identical cable group compatibility: RG-174, RG-188, and RG-316. Cable selection and termination procedures remain unchanged when substituting the Pomona Electronics 72954 for the TE Connectivity AMP 5447648-3.

Q: What are the operating temperature specifications for each part?

A: The TE Connectivity AMP 5447648-3 does not specify an operating temperature range in the provided documentation. The Pomona Electronics 72954 specifies an operating temperature range of -65°C to 165°C. This documented range for the substitute part supports a wider range of environmental applications without introducing incompatibility for applications within the unspecified range of the original part.

Q: Is the packaging identical between these parts?

A: Both parts are supplied in Bulk packaging. The TE Connectivity AMP 5447648-3 includes 3 pcs per package (1 Connector, 1 Contact, 1 Ferrule), and the Pomona Electronics 72954 includes identical packaging contents (3 pcs - 1 Connector, 1 Contact, 1 Ferrule).
