Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 447647-2 are identified based on electrical and mechanical parameter equivalence. The primary substitution criteria include:

Electrical Parameters:

• Connector style (SMA)
• Connector type (Plug, Male Pin)
• Impedance (50 Ohms)
• Maximum frequency (12.4 GHz)
• Number of ports (1)

Mechanical Parameters:

• Contact termination method (Crimp)
• Shield termination method (Crimp)
• Mounting type (Free Hanging/In-Line)
• Fastening type (Threaded)
• Mating cycle rating (500)

Cable Compatibility:

• Support for RG-142, 142A, 142B, and 400 cable groups

Parts meeting all these criteria are classified as direct equivalents. Parts meeting the core electrical and mechanical parameters but with extended cable group support or enhanced material specifications are classified as compatible substitutes.

Engineering Selection Recommendations

Direct Equivalent: 5447647-2

The 5447647-2 from TE Connectivity AMP Connectors is a direct equivalent to the 447647-2. Both parts share identical electrical and mechanical specifications, including SMA connector style, 50 Ohm impedance, crimp termination, and 12.4 GHz maximum frequency. The 5447647-2 provides an upgrade path with RoHS Compliance status, whereas the original 447647-2 is RoHS non-compliant. Both parts are classified as obsolete; however, the 5447647-2 offers improved environmental compliance for new designs and procurement cycles.

Compatible Substitute: 901-9511-1SFC

The 901-9511-1SFC from Amphenol RF is a compatible substitute meeting all core electrical and mechanical parameters. This part maintains SMA connector style, 50 Ohm impedance, crimp termination, and 12.4 GHz frequency rating. The 901-9511-1SFC is classified as Active product status, ensuring long-term availability. Key differentiators include stainless steel body construction, gold-plated center contact, PTFE dielectric material, and extended cable group support (RG-55, 142, 223, 400). The part includes weatherproof ingress protection and operates across -65°C to 165°C temperature range. ROHS3 Compliance and REACH Affected status indicate current regulatory alignment. The 901-9511-1SFC includes four components (connector, contact, ferrule, heat shrink) compared to three components in the original part.

Frequently Asked Questions (FAQ)

Q: Can the 5447647-2 be used as a direct replacement for the 447647-2?

A: Yes. The 5447647-2 is a direct equivalent with identical electrical and mechanical specifications. Both parts feature SMA connector style, 50 Ohm impedance, crimp termination, and 12.4 GHz maximum frequency. The primary difference is RoHS Compliance status, with the 5447647-2 offering improved environmental compliance.

Q: What are the key differences between the 447647-2 and the 901-9511-1SFC?

A: Both parts meet core electrical and mechanical requirements for SMA 50 Ohm crimp connectors. Differences include manufacturer (TE Connectivity versus Amphenol RF), body material (brass versus stainless steel), center contact plating (unspecified versus gold), product status (obsolete versus active), and cable group support (RG-142, 142A, 142B, 400 versus RG-55, 142, 223, 400). The 901-9511-1SFC includes weatherproof ingress protection and operates across -65°C to 165°C.

Q: Is the 901-9511-1SFC compatible with RG-142 cables?

A: Yes. The 901-9511-1SFC supports RG-55, 142, 223, and 400 cable groups, which includes RG-142 compatibility. This part is suitable for applications requiring RG-142 cable termination.

Q: What is the difference in packaging between these parts?

A: The 447647-2 and 5447647-2 packaging information is not specified in the provided data. The 901-9511-1SFC is supplied in bulk packaging. The 901-9511-1SFC includes four components (connector, contact, ferrule, heat shrink), while the 447647-2 and 5447647-2 include three components (connector, contact, ferrule).

Q: Are all three parts RoHS compliant?

A: No. The 447647-2 is RoHS non-compliant. The 5447647-2 is RoHS Compliant. The 901-9511-1SFC is ROHS3 Compliant. For applications requiring RoHS compliance, the 5447647-2 or 901-9511-1SFC are appropriate selections.

Q: Which part should be selected for new designs?

A: For new designs, the 901-9511-1SFC is recommended due to active product status, ensuring long-term availability and supply chain stability. This part also provides ROHS3 Compliance, REACH Affected status, and extended operating temperature range (-65°C to 165°C). Both the 447647-2 and 5447647-2 are classified as obsolete.

Q: Can these connectors be used interchangeably in existing assemblies?

A: The 5447647-2 is a direct equivalent and can be used interchangeably with the 447647-2 in existing assemblies. The 901-9511-1SFC is a compatible substitute; however, the stainless steel body construction, gold-plated center contact, and weatherproof ingress protection represent material and performance enhancements that may affect assembly procedures or performance characteristics in specific applications.
