Pomona Electronics 72965 SMA Coaxial Connector Adapter

Part Overview

The Pomona Electronics 72965 is a coaxial connector adapter designed to convert SMA Plug (male pin) connections to SMA Jack (female socket) connections at 50 Ohms impedance. This right-angle adapter operates across RF frequencies up to 18 GHz and is constructed with gold-plated brass body and beryllium copper center contacts.

The 72965 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring SMA plug-to-jack conversion with equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Pomona Electronics 72965 is determined by the following critical parameters:

• Adapter Series: Must be SMA to SMA
• Adapter Type: Must be Plug to Jack conversion
• Center Gender Configuration: Must convert Female to Male
• Impedance: Must be 50 Ohms
• Style: Must be Right Angle
• Mounting Type: Must be Free Hanging (In-Line), Right Angle
• Fastening Type: Must be Threaded, Threaded
• Dielectric Material: Must be Polytetrafluoroethylene (PTFE)
• Operating Temperature Range: Must support -65°C ~ 165°C minimum
• Mating Cycles: Must support 500 cycles minimum

The Amphenol RF 901-9219-ASF meets these substitution criteria. While the maximum frequency specification differs (12 GHz versus 18 GHz), the adapter maintains functional equivalence for applications operating within the 12 GHz limit. The body material composition differs (stainless steel versus brass), but both materials provide equivalent mechanical and environmental performance for this connector class.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol RF 901-9219-ASF is an active product with current manufacturing support, whereas the Pomona Electronics 72965 is obsolete. Both parts maintain ROHS3 compliance and equivalent operating temperature specifications.

Selection between these parts depends on application frequency requirements. The Pomona 72965 supports operation to 18 GHz, while the Amphenol RF 901-9219-ASF is rated to 12 GHz. For applications operating at frequencies below 12 GHz, the Amphenol RF part provides equivalent functionality with the advantage of active product status and ongoing availability.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 901-9219-ASF directly replace the Pomona Electronics 72965?

A: The Amphenol RF 901-9219-ASF is functionally equivalent for applications operating at frequencies up to 12 GHz. Both adapters provide SMA plug-to-jack conversion at 50 Ohms impedance with identical mechanical mounting and mating cycle specifications. Applications requiring operation above 12 GHz must use the Pomona 72965 or equivalent high-frequency rated adapters.

Q: What is the significance of the frequency rating difference?

A: The Pomona 72965 is rated to 18 GHz maximum frequency, while the Amphenol RF 901-9219-ASF is rated to 12 GHz. This difference reflects the maximum operating frequency for which the adapter maintains specified electrical performance. Selection must align with the actual operating frequency of the application.

Q: Are the body material differences significant?

A: The Pomona 72965 uses gold-plated brass, while the Amphenol RF 901-9219-ASF uses stainless steel. Both materials provide equivalent mechanical strength, environmental protection, and RF performance for this connector class. Material selection does not affect functional substitution.

Q: Do both adapters support the same operating temperature range?

A: Yes. Both the Pomona 72965 and Amphenol RF 901-9219-ASF operate across -65°C to 165°C, providing equivalent thermal performance for industrial and aerospace applications.

Q: What packaging considerations apply to these adapters?

A: The Pomona 72965 is available in standard packaging, while the Amphenol RF 901-9219-ASF is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance.
