Key Parameters

Substitute Part Grouping Explanation

Substitution for the UM-LR-PC(47) is determined by strict equivalence across the following critical parameters:

• Connector Style: U.FL (UMCC)
• Connector Type: Receptacle, Male Pin
• Impedance: 50 Ohms
• Mounting Type: Through Hole, Right Angle
• Contact and Shield Termination: Solder
• Frequency Rating: 3 GHz maximum
• Operating Temperature Range: -30°C ~ 85°C
• Mating Cycles: 500
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these parameters are classified as parametric equivalents and may be used interchangeably in the same application. The UM-LR-PC-A(40) is identified as the manufacturer-recommended substitute, while UM-LR-PC-4(40) is a parametric equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The UM-LR-PC(47) is designated Last Time Buy, making transition to an active part necessary for ongoing production and new designs. Both substitute parts—UM-LR-PC-A(40) and UM-LR-PC-4(40)—maintain full electrical and mechanical equivalence with the original part across all specified parameters.

UM-LR-PC-A(40) is the manufacturer-recommended substitute and carries Active product status, ensuring long-term availability and supply chain stability. UM-LR-PC-4(40) is a parametric equivalent also in Active status with identical specifications. Both parts are ROHS3 compliant and maintain the same impedance, frequency rating, operating temperature range, and mating cycle rating as the original.

Selection between the two active alternatives should be based on availability, lead time, and procurement preference, as both meet all specified engineering requirements for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can UM-LR-PC-A(40) and UM-LR-PC-4(40) be used interchangeably with UM-LR-PC(47)?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: U.FL (UMCC) connector style, 50 Ohm impedance, through-hole right-angle solder termination, 3 GHz frequency rating, and identical operating temperature and mating cycle specifications. Both are ROHS3 compliant with MSL 1 rating.

Q: Why is UM-LR-PC(47) being discontinued?

A: The part is designated Last Time Buy, indicating the manufacturer has ceased production. UM-LR-PC-A(40) and UM-LR-PC-4(40) are active alternatives that provide equivalent functionality for new designs and ongoing production.
