Substitute Part Grouping Explanation

Substitute parts for the 142-0701-326 are classified based on strict electrical and mechanical parameter matching:

Parametric Equivalent (142-0701-306): This Cinch Connectivity Solutions part maintains identical specifications across all critical parameters: SMA jack female socket, 50 ohm impedance, through-hole right-angle mounting, solder termination, 18 GHz maximum frequency, -65°C to 165°C operating range, and 500 mating cycles. The only variance is RoHS compliance status (ROHS3 vs. RoHS Compliant) and REACH applicability. This part is directly substitutable with no functional or mechanical compromise.

Similar Manufacturer Part (0733910080): The Molex 0733910080 matches all core electrical and mechanical parameters: SMA jack female socket, 50 ohm impedance, through-hole right-angle mounting, solder termination, 18 GHz maximum frequency, -65°C to 165°C operating range, and 500 mating cycles. Differences include body material (zinc alloy vs. brass), higher voltage rating (500 V vs. 335 V), packaging format (tray vs. bulk), and RoHS/REACH compliance status. This part functions as a cross-manufacturer substitute where voltage rating and material composition are acceptable for the application.

Parameter Comparison

Engineering Selection Recommendations

142-0701-306 Selection: This part is the primary substitute for the 142-0701-326. Both parts are manufactured by Cinch Connectivity Solutions with identical electrical and mechanical specifications. The 142-0701-306 carries ROHS3 compliance and REACH applicability status, providing enhanced regulatory alignment for applications subject to current environmental standards. Higher inventory availability (13307 units) supports extended procurement windows.

0733910080 Selection: The Molex 0733910080 serves as a cross-manufacturer alternative where supply constraints on Cinch parts exist. This part maintains all critical RF and mechanical parameters. The higher voltage rating (500 V vs. 335 V) provides additional margin for applications with elevated voltage requirements. Zinc alloy body construction differs from brass but maintains equivalent RF performance and environmental durability. ROHS3 compliance and REACH unaffected status apply. Tray packaging requires consideration for assembly workflow integration.

Frequently Asked Questions (FAQ)

Q: Can 142-0701-306 be used as a direct replacement for 142-0701-326?

A: Yes. Both parts are identical in electrical and mechanical specifications. The 142-0701-306 is a parametric equivalent with matching impedance, frequency response, operating temperature range, mating cycles, and mounting configuration. RoHS compliance status differs (ROHS3 vs. RoHS Compliant), which may be advantageous depending on regulatory requirements.

Q: What are the key differences between the Cinch 142-0701-326 and the Molex 0733910080?

A: Both parts share identical SMA jack configuration, 50 ohm impedance, 18 GHz frequency capability, and operating temperature range. Differences include body material (brass vs. zinc alloy), voltage rating (335 V vs. 500 V), packaging format (bulk vs. tray), and regulatory compliance status. These differences do not affect RF performance or mechanical compatibility in standard applications.

Q: Is the higher voltage rating of the Molex 0733910080 significant?

A: The 500 V rating on the Molex part exceeds the 335 V specification of the Cinch parts. This provides additional safety margin in applications where voltage stress is a design consideration. For applications operating within the 335 V specification, both parts perform equivalently.

Q: Does body material affect RF performance?

A: No. The brass body of the Cinch parts and the zinc alloy body of the Molex part both support equivalent RF performance at 50 ohms impedance through 18 GHz. Material selection affects mechanical durability and environmental resistance but not electrical characteristics for this connector class.

Q: What packaging considerations apply to these substitutes?

A: The 142-0701-326 and 142-0701-306 are supplied in bulk packaging. The Molex 0733910080 is supplied in tray packaging. Bulk packaging supports manual assembly workflows, while tray packaging accommodates automated pick-and-place systems. Selection depends on assembly process requirements.

Q: Are all three parts RoHS compliant?

A: Yes. The 142-0701-326 carries RoHS Compliant status. Both 142-0701-306 and 0733910080 carry ROHS3 Compliant status, representing current environmental compliance standards. All parts are suitable for applications requiring RoHS compliance.
