Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 415490-1 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Connector style and type (SMB Mini Jack configuration)
• Impedance specification (75 Ohms)
• Mounting configuration (through-hole, right-angle solder)
• Frequency capability (4 GHz maximum)
• Fastening mechanism (snap-on)
• Number of ports (single port)

Material and Environmental Compatibility:

• Dielectric material (PTFE)
• Center contact and body materials (brass construction)
• Operating temperature range compatibility
• Voltage rating (335 V)
• Moisture sensitivity level (MSL 1)

The Molex 0731000259 qualifies as a functional substitute based on matching all critical electrical parameters, identical mounting specifications, and compatible material composition. Both connectors maintain 75 Ohm impedance, support 4 GHz frequency operation, utilize PTFE dielectric, and employ snap-on fastening in through-hole right-angle configurations.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0731000259 serves as the primary substitute for the obsolete TE Connectivity 415490-1 based on the following engineering criteria:

Compliance and Regulatory Status: The Molex 0731000259 maintains active product status with ROHS3 compliance, ensuring continued availability and regulatory alignment for new designs and production requirements. The TE Connectivity 415490-1, classified as obsolete, presents supply chain risk and limited long-term procurement viability.

Electrical and Mechanical Equivalence: Both connectors maintain identical impedance (75 Ohms), frequency capability (4 GHz), and mounting configuration (through-hole, right-angle solder). Voltage ratings are equivalent at 335 V, and both employ identical dielectric materials (PTFE) and contact materials (brass).

Environmental Operating Range: The Molex 0731000259 operates across -55°C to 155°C, which encompasses the majority of standard industrial and commercial applications. The TE Connectivity 415490-1 offers an extended lower temperature limit (-65°C) and higher upper limit (165°C). Applications requiring the full -65°C to 165°C range require evaluation of alternative solutions or confirmation that the Molex operating range satisfies specific requirements.

Connector Type Consideration: The TE Connectivity 415490-1 is configured as a jack with male pin, while the Molex 0731000259 is a receptacle with male pin. Mating interface compatibility must be verified against the corresponding connector on the cable or mating component to ensure proper mechanical and electrical connection.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0731000259 directly replace the TE Connectivity 415490-1 in existing designs?

A: Direct replacement requires verification of the mating connector type. The TE Connectivity 415490-1 is a jack configuration, while the Molex 0731000259 is a receptacle. The mating component must be compatible with the receptacle type. Both connectors share identical electrical specifications (75 Ohms, 4 GHz, 335 V) and mounting configuration (through-hole, right-angle solder).

Q: What is the difference between jack and receptacle connector types in SMB configurations?

A: In SMB connectors, the jack typically accepts a male pin from a mating plug, while the receptacle also accepts a male pin but from a different mating interface design. The specific mating component determines which type is required. Verify the existing mating connector before selecting a substitute.

Q: Are there operating temperature limitations when substituting the Molex part?

A: The Molex 0731000259 operates from -55°C to 155°C, compared to the TE Connectivity 415490-1 range of -65°C to 165°C. Applications requiring operation below -55°C or above 155°C must confirm that the Molex operating range satisfies system requirements or pursue alternative solutions.

Q: Do both connectors meet RoHS compliance requirements?

A: Yes. The TE Connectivity 415490-1 is RoHS Compliant, and the Molex 0731000259 is ROHS3 Compliant. Both meet current RoHS standards for new product designs and manufacturing.

Q: What is the significance of the MSL rating for both connectors?

A: Both connectors carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture sensitivity concerns. No special storage or handling precautions are required for either connector.

Q: Are the impedance and frequency specifications identical between the two connectors?

A: Yes. Both the TE Connectivity 415490-1 and Molex 0731000259 maintain 75 Ohm impedance and support operation up to 4 GHz, ensuring electrical compatibility in RF applications.

Q: What packaging considerations apply to the Molex substitute?

A: The Molex 0731000259 is supplied in bulk packaging. Verify that bulk packaging meets procurement and inventory management requirements for your application.
