Substitute Part Grouping Explanation

Substitution of the UM-R-PC(40) is permissible with UM-R-PC-1(40) based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is determined by the following key parameters:

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

Both parts share identical specifications across these parameters, confirming direct substitutability for RF coaxial connector applications.

Parameter Comparison

Engineering Selection Recommendations

Both UM-R-PC(40) and UM-R-PC-1(40) are Active product status components manufactured by Hirose Electric Co Ltd. Both parts maintain ROHS3 compliance and identical electrical specifications for 50 Ohms RF coaxial connector applications. Selection between these parts may be based on inventory availability, as UM-R-PC(40) has 909 pieces in stock and UM-R-PC-1(40) has 961 pieces in stock. No technical differentiation exists between these components for RF connector applications operating within the specified frequency and temperature parameters.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically equivalent U.FL (UMCC) connector receptacles with identical impedance (50 Ohms), frequency rating (3 GHz), operating temperature range (-30°C ~ 85°C), and mating cycle specifications (500 cycles). Direct substitution is permissible without circuit redesign or PCB layout modification.

Q: Are there any compliance differences between these parts?

A: No. Both UM-R-PC(40) and UM-R-PC-1(40) are ROHS3 compliant with MSL rating of 1 (Unlimited). Both carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications.

Q: What determines substitutability for U.FL (UMCC) connectors?

A: Substitutability is determined by matching connector style, connector type (Receptacle, Male Pin), impedance (50 Ohms), mounting type (Through Hole), termination method (Solder), frequency rating (3 GHz maximum), operating temperature range (-30°C ~ 85°C), and mating cycle rating (500 cycles). All these parameters are identical between UM-R-PC(40) and UM-R-PC-1(40).

Q: Does packaging affect substitution eligibility?

A: No. Both parts are supplied in Bag packaging. Packaging format does not affect electrical or mechanical compatibility for connector applications.

Q: Are there any material or plating differences?

A: No. Both parts feature identical materials: Brass body with Nickel finish, Brass center contact with Gold plating, and Polytetrafluoroethylene (PTFE) dielectric material.
