TE Connectivity 5447647-3 SMA Connector Plug Equivalent & Substitute Parts

Part Overview

The TE Connectivity 5447647-3 is an SMA connector plug with male pin configuration, designed for 50-ohm coaxial cable termination using crimp contact technology. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing procurement and system integration. The connector supports free-hanging (in-line) mounting with threaded fastening and operates across RF applications up to 12.4 GHz. Substitute parts must maintain electrical and mechanical compatibility while offering active product status and current manufacturing support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 5447647-3 are qualified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Core Compatibility Parameters:

• Connector Style: SMA (exact match required)
• Connector Type: Plug, Male Pin (exact match required)
• Impedance: 50 Ohms (exact match required)
• Contact Termination: Crimp (exact match required)
• Shield Termination: Crimp (exact match required)
• Mounting Type: Free Hanging (In-Line) (exact match required)
• Fastening Type: Threaded (exact match required)
• Frequency - Max: 12.4 GHz (exact match required)
• Number of Ports: 1 (exact match required)
• Mating Cycles: 500 (exact match required)

Identified Substitutes:

1. Amphenol SV Microwave M39012/55B3112 – Direct manufacturer equivalent with active product status
2. Amphenol RF 901-155-16 – Similar manufacturer equivalent with active product status and extended cable group compatibility

Both substitute parts satisfy all core compatibility parameters and offer active manufacturing status, addressing the obsolescence of the original TE Connectivity component.

Parameter Comparison

Engineering Selection Recommendations

Amphenol SV Microwave M39012/55B3112 is qualified as a direct manufacturer equivalent. This part maintains all core electrical and mechanical parameters while offering active product status and ROHS3 compliance. The component is suitable for applications requiring standard cable group compatibility (RG-174, 316).

Amphenol RF 901-155-16 is qualified as a similar manufacturer equivalent with extended cable group support. This part accommodates a broader range of cable specifications including RG-174, 188, 188A, 316, LMR-100, and M17/119-RG174. The component provides active product status, ROHS3 compliance, and weatherproof ingress protection. Selection of this part is appropriate for applications requiring flexibility across multiple cable types or enhanced environmental protection.

Both substitute parts satisfy regulatory compliance requirements (ROHS3, REACH Affected) and maintain the 500 mating cycle rating of the original component. Selection between substitutes depends on specific cable group requirements and environmental operating conditions of the target application.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol SV Microwave M39012/55B3112 directly replace the TE Connectivity 5447647-3?

A: Yes. Both parts share identical electrical specifications (SMA, 50 Ohm, 12.4 GHz maximum frequency) and mechanical configuration (crimp termination, threaded fastening, free-hanging mounting). The Amphenol part is active and currently manufactured, addressing the obsolescence of the TE Connectivity component.

Q: What is the primary difference between the two substitute parts?

A: The Amphenol RF 901-155-16 supports an extended cable group range (RG-174, 188, 188A, 316, LMR-100, M17/119-RG174) compared to the Amphenol SV Microwave M39012/55B3112 (RG-174, 316). The Amphenol RF part also includes weatherproof ingress protection. Both parts maintain identical core RF and mechanical parameters.

Q: Are there packaging differences between the original and substitute parts?

A: Yes. The TE Connectivity 5447647-3 includes 3 pieces (1 Connector, 1 Contact, 1 Ferrule). The Amphenol SV Microwave M39012/55B3112 includes 2 pieces (1 Connector, 1 Heat Shrink). The Amphenol RF 901-155-16 includes 4 pieces (1 Connector, 1 Contact, 1 Ferrule, 1 Heat Shrink). Procurement specifications should account for these package composition differences.

Q: Do the substitute parts meet the same regulatory requirements?

A: Yes. Both substitute parts are ROHS3 compliant and REACH affected, meeting or exceeding the regulatory status of the original TE Connectivity component (RoHS Compliant, REACH Affected).

Q: What is the operating temperature range for the substitute parts?

A: The Amphenol SV Microwave M39012/55B3112 and Amphenol RF 901-155-16 both operate across -65°C to 165°C. The original TE Connectivity 5447647-3 does not specify an operating temperature range in the provided data.

Q: Can the Amphenol RF 901-155-16 be used in applications originally designed for RG-174 cable?

A: Yes. The Amphenol RF 901-155-16 supports RG-174 cable compatibility and maintains all electrical and mechanical parameters required for such applications. The extended cable group support provides additional flexibility without compromising performance for standard RG-174 configurations.
