Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 901-9217 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Critical Matching Parameters:

• Adapter type (Jack to Jack)
• Center gender configuration (Female to Female)
• Impedance (50 Ohms)
• Connector style (Straight)
• Mounting type (Free Hanging/In-Line)
• Fastening mechanism (Threaded connections)
• Operating temperature range (-65°C to 165°C)
• Dielectric material (PTFE)
• Center contact plating (Gold)

Allowable Variation Parameters:

• Frequency maximum rating (12.4 GHz baseline; higher ratings acceptable)
• Adapter series designation (SMA to SMA or OSM to OSM)
• Body material composition (Stainless Steel or Beryllium Copper)
• Product status (Active or Obsolete)
• Manufacturer identity

Two substitute parts meet these criteria: TE Connectivity AMP Connectors 1053488-1 and Pomona Electronics 4284.

Engineering Selection Recommendations

Amphenol RF 901-9217 (Primary Part)

The Amphenol RF 901-9217 is the recommended primary selection. It maintains active product status with current manufacturing support, ROHS3 compliance, and REACH affected designation. This part is suitable for new designs and applications requiring long-term component availability.

TE Connectivity AMP Connectors 1053488-1 (Direct Substitute)

The TE Connectivity 1053488-1 provides electrical and mechanical compatibility with the Amphenol RF 901-9217 across all critical parameters. This part offers a higher frequency maximum rating of 18 GHz, providing extended performance capability within the same 50-ohm impedance class. However, this part carries obsolete product status, indicating discontinued manufacturing. The TE Connectivity part is suitable for replacement applications, legacy system maintenance, or inventory supplementation where existing stock is available. RoHS compliance is confirmed.

Pomona Electronics 4284 (Functional Equivalent)

The Pomona Electronics 4284 provides functional equivalence for the Amphenol RF 901-9217 with matching adapter type, center gender, style, mounting type, fastening mechanism, operating temperature range, and dielectric material. This part maintains active product status with ROHS3 compliance. The impedance specification is not provided in the available data; however, the part is documented as an SMA jack-to-jack adapter with identical mechanical and thermal characteristics. This part is suitable for applications where alternative sourcing from an active manufacturer is required.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1053488-1 be used as a direct replacement for the Amphenol RF 901-9217?

A: Yes. The TE Connectivity 1053488-1 meets all critical electrical and mechanical compatibility parameters: jack-to-jack adapter type, female-to-female center gender, 50-ohm impedance, straight style, free-hanging mounting, threaded fastening, PTFE dielectric, and identical operating temperature range. The higher frequency rating of 18 GHz does not prevent substitution in applications rated to 12.4 GHz. Product status is obsolete; verify stock availability before selection.

Q: What is the difference between the Amphenol RF 901-9217 and the Pomona Electronics 4284?

A: Both parts share identical adapter type, center gender, style, mounting type, fastening type, operating temperature range, and dielectric material. The Amphenol part specifies 50-ohm impedance and stainless steel body material. The Pomona part does not specify impedance in available documentation and uses beryllium copper body material. Both maintain active product status and ROHS3 compliance. Electrical performance is equivalent for 50-ohm RF applications.

Q: Are all three parts suitable for new product designs?

A: The Amphenol RF 901-9217 and Pomona Electronics 4284 are both active products suitable for new designs. The TE Connectivity 1053488-1 carries obsolete status and is not recommended for new designs unless legacy system compatibility is required.

Q: What is the significance of the 18 GHz frequency rating on the TE Connectivity part?

A: The TE Connectivity 1053488-1 specifies a maximum frequency of 18 GHz compared to 12.4 GHz for the Amphenol and Pomona parts. This indicates broader frequency response capability. In applications operating at or below 12.4 GHz, this difference does not affect performance. The higher rating provides additional margin for future applications or system upgrades within the same connector class.

Q: Does the Pomona Electronics 4284 lack impedance specification?

A: The Pomona Electronics 4284 is documented as an SMA jack-to-jack adapter with gold-plated contacts, PTFE dielectric, and beryllium copper center contact material. Impedance specification is not provided in the available technical data. For applications requiring confirmed 50-ohm impedance, the Amphenol RF 901-9217 or TE Connectivity 1053488-1 are preferred selections.

Q: What is the mating cycle rating significance?

A: The TE Connectivity 1053488-1 specifies 500 mating cycles. The Amphenol RF 901-9217 and Pomona Electronics 4284 do not specify mating cycle ratings in available data. Mating cycle rating indicates mechanical durability for repeated connection and disconnection operations. For applications involving frequent mating cycles, the TE Connectivity specification provides documented performance data.

Q: Are all three parts RoHS compliant?

A: Yes. The Amphenol RF 901-9217 and Pomona Electronics 4284 are ROHS3 compliant. The TE Connectivity 1053488-1 is RoHS compliant. All three parts meet regulatory requirements for restricted substance elimination in electronic components.
