Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol RF 901-101 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector Style: SMA (industry standard RF interface)
• Connector Type: Plug, Male Pin (mating interface requirement)
• Impedance: 50 Ohms (electrical characteristic for signal integrity)
• Contact Termination: Crimp (assembly method compatibility)
• Shield Termination: Crimp (assembly method compatibility)
• Frequency - Max: 12.4 GHz (operational bandwidth requirement)
• Fastening Type: Threaded (mechanical coupling method)
• Number of Ports: 1 (single-port configuration)
• Dielectric Material: Polytetrafluoroethylene (PTFE) (electrical performance material)

Secondary Compatibility Criteria:

• Cable Group compatibility (RG-55, 142, 223, 400 for main part)
• Mating Cycles: 500 (mechanical durability specification)
• Voltage Rating: 500 V (electrical stress rating)
• Operating Temperature: -65°C ~ 165°C (environmental operating range)

The TE Connectivity AMP Connectors part 5447647-2 qualifies as a substitute based on matching all primary criteria and the majority of secondary criteria. Differences in mounting type (Free Hanging In-Line versus standard mounting) and body material composition do not affect core electrical or mechanical substitution compatibility for this connector category.

Parameter Comparison

Engineering Selection Recommendations

Amphenol RF 901-101 Selection Criteria:

• Active product status ensures ongoing manufacturer support and availability
• ROHS3 compliance provides the highest environmental regulatory standard
• Gold plating on beryllium copper body and center contact offers superior corrosion resistance and electrical conductivity
• Standard mounting configuration suits fixed installation applications
• Current inventory of 971 units supports immediate procurement

TE Connectivity 5447647-2 Selection Criteria:

• Obsolete product status indicates discontinued manufacturing and limited future availability
• RoHS compliant status meets regulatory requirements but does not include ROHS3 designation
• Nickel body finish with unspecified center contact plating provides adequate but lower corrosion resistance compared to gold plating
• Free Hanging (In-Line) mounting type accommodates flexible cable routing and panel-mount applications
• Higher inventory level of 1144 units currently available
• Includes packaged components (connector, contact, ferrule) for simplified assembly

Substitution Decision Logic: The TE Connectivity 5447647-2 functions as an electrical and mechanical equivalent for applications requiring SMA male plug connectors with 50-ohm impedance and 12.4 GHz frequency capability. The primary consideration for substitution is the obsolete product status of the TE part, which may limit long-term supply chain reliability. The Amphenol RF 901-101 is the preferred selection for new designs and applications requiring extended product lifecycle support. The TE Connectivity part is suitable for replacement applications where the Free Hanging mounting configuration is specifically required and where the application can tolerate the lower corrosion resistance of nickel plating.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5447647-2 directly replace the Amphenol RF 901-101 in existing assemblies?

A: Electrical and mechanical substitution is possible for applications using RG-142 or RG-400 cable groups. The Free Hanging mounting type of the TE part may require mechanical redesign of the installation fixture or panel mount. The nickel body finish has lower corrosion resistance than the gold-plated beryllium copper of the Amphenol part, which may affect performance in high-humidity or corrosive environments.

Q: What cable types are compatible with each connector?

A: The Amphenol RF 901-101 supports RG-55, RG-142, RG-223, and RG-400 cable groups. The TE Connectivity 5447647-2 supports RG-142, RG-142A, RG-142B, and RG-400 cable groups. Both connectors are compatible with RG-142 and RG-400 cables.

Q: Are there regulatory compliance differences between these parts?

A: Both parts are RoHS compliant and carry EAR99 ECCN classification. The Amphenol RF 901-101 meets ROHS3 compliance, which is a higher environmental standard than the RoHS compliance of the TE Connectivity part. Both parts have MSL 1 (Unlimited) moisture sensitivity rating and are REACH affected or vendor-defined.

Q: What is the significance of the product status difference?

A: The Amphenol RF 901-101 is in active production status, ensuring ongoing manufacturer support, quality consistency, and long-term availability. The TE Connectivity 5447647-2 is obsolete, meaning the manufacturer has discontinued production. Obsolete parts may have limited inventory availability and no guarantee of future supply.

Q: How do the material and finish differences affect performance?

A: The Amphenol part uses beryllium copper with gold plating, providing superior electrical conductivity and corrosion resistance. The TE Connectivity part uses brass with nickel plating, which provides adequate electrical performance but lower corrosion resistance. For applications in harsh environments or requiring maximum signal integrity, the gold-plated beryllium copper is preferred.

Q: What does the Free Hanging (In-Line) mounting type mean?

A: Free Hanging (In-Line) mounting indicates the connector is designed for direct cable attachment without a fixed panel or chassis mount. This configuration allows flexible cable routing and is suitable for applications where the connector moves with the cable. Standard mounting typically refers to fixed installation on a panel or chassis.

Q: Are the mating cycles equivalent?

A: Both connectors specify 500 mating cycles, indicating equivalent mechanical durability for connection and disconnection operations.

Q: What is the operating temperature range for each part?

A: The Amphenol RF 901-101 specifies an operating temperature range of -65°C to 165°C. The TE Connectivity 5447647-2 does not provide an operating temperature specification in the available data.
