Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UM-R-PC-7(40) is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: U.FL (UMCC)
• Connector Type: Receptacle, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Solder
• Mounting Type: Through Hole
• Fastening Type: Snap-On
• Number of Ports: 1

Allowable Variation Parameters:

• Frequency - Max: May exceed 1 GHz (backward compatible)
• Operating Temperature Range: May be narrower than -55°C ~ 85°C (application-dependent)
• Product Status: Active preferred over obsolete
• RoHS Compliance: ROHS3 acceptable as upgrade from RoHS Compliant

The UM-R-PC(40) meets all mandatory matching criteria and represents the direct active equivalent for the obsolete UM-R-PC-7(40).

Parameter Comparison

Engineering Selection Recommendations

The UM-R-PC(40) is the direct equivalent substitute for the obsolete UM-R-PC-7(40). Selection is based on the following engineering criteria:

Product Status: The UM-R-PC(40) carries active product status from Hirose Electric Co Ltd, ensuring ongoing availability and manufacturing support. The UM-R-PC-7(40) is obsolete and subject to supply discontinuation.

Compliance Certifications: Both parts maintain RoHS compliance. The UM-R-PC(40) achieves ROHS3 certification, representing enhanced regulatory alignment compared to the base RoHS Compliant status of the main part.

Electrical and Mechanical Compatibility: All critical parameters for connector interface, impedance, termination method, and mounting configuration are identical between the two parts. The UM-R-PC(40) provides enhanced frequency capability (3 GHz versus 1 GHz), which is backward compatible with applications designed for the lower frequency specification.

Temperature Operating Range: The UM-R-PC(40) operates within -30°C ~ 85°C. Applications requiring the full -55°C lower temperature limit of the original part must evaluate specific environmental requirements before substitution.

Supply Chain Continuity: With 909 pieces in stock versus 810 pieces for the obsolete variant, the UM-R-PC(40) provides improved inventory availability for production and replacement needs.

Frequently Asked Questions (FAQ)

Q: Can the UM-R-PC(40) be used as a direct replacement for the UM-R-PC-7(40) in existing designs?

A: Yes. The UM-R-PC(40) is electrically and mechanically compatible with the UM-R-PC-7(40). All connector interface parameters, impedance, termination methods, and mounting configurations are identical. No PCB redesign or assembly process modification is required.

Q: What is the difference in frequency capability between these parts?

A: The UM-R-PC-7(40) is rated to 1 GHz maximum frequency, while the UM-R-PC(40) is rated to 3 GHz. The higher frequency rating of the substitute part is backward compatible with applications designed for lower frequencies and does not introduce incompatibility.

Q: Are there temperature range limitations when substituting the UM-R-PC(40)?

A: The UM-R-PC(40) operates within -30°C ~ 85°C, compared to the -55°C ~ 85°C range of the original part. Applications requiring operation below -30°C must evaluate whether this narrower range meets specific environmental or operational requirements.

Q: What is the packaging difference between these parts?

A: The UM-R-PC-7(40) packaging is not specified in available documentation. The UM-R-PC(40) is supplied in bag packaging. Confirm packaging requirements with your procurement or assembly process specifications.

Q: Are both parts RoHS compliant?

A: Yes. The UM-R-PC-7(40) is RoHS Compliant. The UM-R-PC(40) is ROHS3 Compliant, representing enhanced regulatory certification. Both parts meet RoHS requirements for restricted substance elimination.

Q: What is the base product number relationship?

A: Both the UM-R-PC-7(40) and UM-R-PC(40) share the base product number UM-R-PC. The numeric suffix and variant designation indicate manufacturing revisions or configuration updates within the same product family.
