Key Parameters

Substitute Part Grouping Explanation

Substitution for the UM-QLP-1.5-6(40) is determined by strict equivalence across the following critical parameters:

• Connector Style & Type: U.FL (UMCC) Plug, Female Socket configuration
• Electrical Specification: 50-ohm impedance and 2 GHz maximum frequency
• Termination Method: Solder contact termination with crimp shield termination
• Mounting Configuration: Free hanging (in-line), right-angle orientation
• Material & Finish Specifications: Beryllium copper center contact with gold plating, brass body with nickel finish, PTFE dielectric
• Environmental Compliance: RoHS compliant, MSL 1 (unlimited moisture sensitivity level)
• Mechanical Durability: 500 mating cycles minimum

The substitute part UM-QLP-1.5-6(41) maintains identical electrical, mechanical, and environmental specifications across all these parameters, establishing it as a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both UM-QLP-1.5-6(40) and UM-QLP-1.5-6(41) are Active status components from Hirose Electric Co Ltd with identical RoHS compliance and MSL 1 ratings. Selection between these parts should be based on inventory availability and supply chain requirements. The UM-QLP-1.5-6(40) currently maintains 738 pieces in stock, while the UM-QLP-1.5-6(41) maintains 748 pieces. Both parts are suitable for immediate integration into designs requiring U.FL (UMCC) coaxial connectors with 50-ohm impedance and 2 GHz frequency capability. No electrical or mechanical performance differentiation exists between these components.

Frequently Asked Questions (FAQ)

Q: Can UM-QLP-1.5-6(41) be used as a direct replacement for UM-QLP-1.5-6(40)?

A: Yes. Both parts are parametrically equivalent across all electrical, mechanical, and environmental specifications. They share identical impedance (50 ohms), frequency rating (2 GHz), mounting configuration (free hanging, right angle), termination methods (solder contact, crimp shield), and material compositions. No circuit redesign or PCB layout modification is required.

Q: Are there any compatibility concerns when substituting between these parts?

A: No. The parts are mechanically and electrically interchangeable. Both use identical U.FL (UMCC) connector geometry, mating cycle ratings (500), and operating temperature ranges (-30°C ~ 85°C). Cable group compatibility (1.5D-2V, 1.5D-HQEV, 1.5D-QEV) is identical for both parts.

Q: What determines substitution eligibility for U.FL (UMCC) connectors?

A: Substitution eligibility is determined by matching connector style, impedance, frequency rating, mounting type, contact termination method, and material specifications. For the UM-QLP-1.5-6 series, the critical parameters are 50-ohm impedance, 2 GHz maximum frequency, solder termination, and right-angle free-hanging configuration. Deviations in any of these parameters disqualify a part from substitution.

Q: What is the significance of the part number suffix (40 vs 41)?

A: The suffix differentiates manufacturing batches or production variants within the same base product number (UM-QLP-1). Both suffixes represent the same electrical and mechanical specification, ensuring full interchangeability. The distinction is administrative rather than functional.

Q: Are both parts suitable for high-frequency RF applications?

A: Yes. Both parts are rated for frequencies up to 2 GHz and maintain 50-ohm impedance across this range. The PTFE dielectric material and gold-plated beryllium copper contacts support consistent RF performance. Operating temperature range (-30°C ~ 85°C) accommodates standard industrial and commercial RF applications.
