Substitute Part Grouping Explanation

Substitution eligibility for the UM-LR-PC(41) is determined by strict equivalence across the following critical parameters: connector style (U.FL UMCC), connector type (receptacle with male pin), impedance (50 ohms), mounting configuration (through-hole right-angle), termination method (solder contact and shield), and frequency rating (1 GHz maximum). All identified substitutes maintain these core electrical and mechanical specifications.

The UM-LR-PC-A(41) qualifies as a manufacturer-recommended alternative with identical electrical characteristics. The UM-LR-PC-4-1(41) and UM-QLR-PC-1(40) are parametric equivalents that preserve all critical RF and mechanical parameters while differing in product status and operating temperature range.

Engineering Selection Recommendations

For applications requiring full parameter alignment with the UM-LR-PC(41), the UM-QLR-PC-1(40) is the preferred substitute. This part maintains identical electrical specifications, mating cycle rating, and RoHS compliance while offering Active product status, ensuring continued availability and supply chain stability. The operating temperature range of -30°C to 85°C is suitable for most commercial and industrial RF applications.

The UM-LR-PC-A(41) is the manufacturer-recommended alternative and provides direct compatibility with equivalent electrical performance and identical operating temperature range. This option is optimal when manufacturer-specified substitution is required.

The UM-LR-PC-4-1(41) is a parametric equivalent suitable for applications where mating cycle requirements do not exceed 500 cycles. This part shares Last Time Buy status with the original component and should be evaluated based on specific design cycle expectations.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are U.FL (UMCC) receptacle connectors with identical impedance (50 ohms), mounting configuration (through-hole right-angle), termination method (solder), and frequency rating (1 GHz). The operating temperature range of UM-QLR-PC-1(40) (-30°C to 85°C) covers standard commercial and industrial applications. Mating cycle ratings are equivalent at 1000 cycles.

Q: What is the difference between UM-LR-PC-A(41) and UM-LR-PC(41)?

A: UM-LR-PC-A(41) is the manufacturer-recommended substitute with identical electrical and mechanical specifications. The primary distinction is product status: UM-LR-PC-A(41) is Active, while UM-LR-PC(41) is Last Time Buy. Both support the same operating temperature range and frequency specifications.

Q: Should UM-LR-PC-4-1(41) be selected over UM-QLR-PC-1(40)?

A: Selection between these parts depends on mating cycle requirements. UM-LR-PC-4-1(41) supports 500 mating cycles, while UM-QLR-PC-1(40) supports 1000 mating cycles. For applications with higher connector engagement frequency, UM-QLR-PC-1(40) is the appropriate choice. UM-QLR-PC-1(40) also offers Active product status.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed substitutes—UM-LR-PC-A(41), UM-LR-PC-4-1(41), and UM-QLR-PC-1(40)—are RoHS compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original UM-LR-PC(41) specification.

Q: What packaging is available for these coaxial connectors?

A: UM-LR-PC(41), UM-LR-PC-4-1(41), and UM-QLR-PC-1(40) are supplied in Bulk packaging. UM-LR-PC-A(41) packaging information is not specified in the available data.
