Equivalent & Substitute Parts for Hirose Electric Co Ltd UM-LR-PC(46) Coaxial Connector (RF)

Part Overview

UM-LR-PC(46) is a Hirose Electric Co Ltd coaxial connector (RF) designed as a U.FL (UMCC) receptacle with a male pin, optimized for 50 Ohms impedance and through-hole, right-angle PCB mounting with solder terminations. The connector features gold-plated brass construction, supports up to 500 mating cycles, and is RoHS3 compliant. The product status is "Obsolete," which necessitates engineering evaluation and selection of substitute or equivalent models for ongoing or new designs requiring identical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute and equivalent parts for the UM-LR-PC(46) coaxial connector (RF) are determined strictly by matching all provided key electrical and mechanical parameters. Substitution is permitted only when the following criteria are identical: connector style (U.FL/UMCC), connector type (Receptacle, Male Pin), impedance (50 Ohms), contact and shield termination method (Solder), mounting type (Through Hole, Right Angle), fastening type (Snap-On), frequency capability (3 GHz), body and contact materials (Brass/Gold), dielectric material (PTFE), operating temperature range, mating cycles, compliance status (RoHS3), and moisture sensitivity (MSL 1).

Parameter Comparison

Engineering Selection Recommendations

When selecting a substitute for the UM-LR-PC(46), confirm that the replacement part is active, ROHS3 compliant, and matches moisture sensitivity criteria (MSL 1). Selection must be limited to parts for which the provided parameters are explicitly matched. Parametric equivalents such as UM-LR-PC-4(40) fulfill these requirements and are suitable for direct substitution. Manufacturer-recommended alternates may be considered only when the product status is active and all required certifications are present.

Frequently Asked Questions (FAQ)

Q1: What defines a suitable substitute for UM-LR-PC(46) coaxial connector (RF)?
A: A suitable substitute must match all provided electrical and mechanical specifications, including 50 Ohm impedance, U.FL (UMCC) connector style, through-hole right angle mounting, solder terminations, snap-on fastening, and relevant materials.

Q2: Is RoHS compliance mandatory for substitution?
A: Yes. All substitutes must be ROHS3 compliant to ensure regulatory compatibility.

Q3: Why is product status critical in substitute selection?
A: Only active parts can be used for ongoing designs; obsolete parts require replacement with equivalents that are currently available and in production.

Q4: Can inventory levels and packaging type affect substitution?
A: Inventory levels and packaging inform availability and handling but do not affect electrical or mechanical compatibility unless specified.

Q5: How is parameter equivalence verified for alternate parts?
A: Equivalence is verified exclusively through matching all provided key parameters in part documentation. Only those stated parameters determine substitute suitability.

Q6: Is it necessary that the substitute belongs to the same series or manufacturer?
A: Substitution is determined by matching the critical application parameters, not by the product series or manufacturer, unless series-specific parameters are essential and provided.
