Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UM-LR-PC-4-1(41) is determined by the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: U.FL (UMCC)
• Connector Type: Receptacle, Male Pin
• Impedance: 50 Ohms
• Mounting Type: Through Hole, Right Angle
• Contact Termination: Solder
• Shield Termination: Solder
• Frequency - Max: 1 GHz
• Number of Ports: 1
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Body Material: Brass
• Center Contact Material: Brass
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation Parameters:

• Operating Temperature Range: Substitute parts must support the minimum operating temperature of -55°C and maximum of 85°C, or exceed these limits
• Mating Cycles: Substitute parts must meet or exceed 500 mating cycles
• Product Status: Active or Last Time Buy status acceptable
• Inventory Availability: No restriction

Two equivalent parts meet these substitution criteria: UM-LR-PC(41) and UM-QLR-PC-1(40).

Parameter Comparison

Engineering Selection Recommendations

UM-LR-PC(41): This part is a direct parametric equivalent with identical electrical and mechanical specifications to the UM-LR-PC-4-1(41). Both share Last Time Buy status. The UM-LR-PC(41) offers improved mating cycle rating (1000 cycles versus 500 cycles) and higher inventory availability (758 units). Selection of this part is appropriate for applications where extended connector lifespan is beneficial.

UM-QLR-PC-1(40): This part meets all mandatory substitution criteria and offers the highest inventory availability (1096 units) with Active product status, providing superior long-term supply chain security. Mating cycle rating is 1000 cycles. The operating temperature range is -30°C to 85°C, which does not extend to -55°C. Selection of this part is appropriate for applications operating within the -30°C to 85°C temperature range.

All three parts are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard PCB assembly and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can UM-LR-PC(41) be used as a direct replacement for UM-LR-PC-4-1(41)?

A: Yes. Both parts are U.FL (UMCC) receptacle connectors with identical electrical specifications (50 Ohms, 1 GHz maximum frequency), mechanical configuration (through-hole, right-angle, solder termination), and operating temperature range (-55°C to 85°C). The UM-LR-PC(41) provides higher mating cycle rating (1000 versus 500 cycles).

Q: Can UM-QLR-PC-1(40) be used as a direct replacement for UM-LR-PC-4-1(41)?

A: Yes, provided the application operates within the -30°C to 85°C temperature range. The UM-QLR-PC-1(40) meets all electrical and mechanical specifications. The operating temperature minimum is -30°C rather than -55°C. Applications requiring operation below -30°C must use UM-LR-PC-4-1(41) or UM-LR-PC(41).

Q: What are the key differences between these three parts?

A: All three parts share identical U.FL (UMCC) connector style, 50 Ohm impedance, through-hole right-angle solder mounting, and 1 GHz frequency rating. Differences are: (1) Operating temperature minimum: UM-LR-PC-4-1(41) and UM-LR-PC(41) support -55°C; UM-QLR-PC-1(40) supports -30°C minimum. (2) Mating cycles: UM-LR-PC-4-1(41) rated for 500 cycles; UM-LR-PC(41) and UM-QLR-PC-1(40) rated for 1000 cycles. (3) Product status: UM-QLR-PC-1(40) is Active; the other two are Last Time Buy.

Q: Are all three parts RoHS Compliant?

A: Yes. All three parts are RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited), suitable for standard PCB assembly processes.

Q: Which part should be selected for new designs?

A: UM-QLR-PC-1(40) is recommended for new designs due to Active product status, highest inventory availability (1096 units), and 1000 mating cycle rating. This part is suitable for applications operating within -30°C to 85°C. For applications requiring -55°C minimum operating temperature, UM-LR-PC(41) is the appropriate selection.
