UG-88/U(56) Equivalent & Substitute Parts

Part Overview

The UG-88/U(56) is a coaxial RF connector plug manufactured by Hirose Electric Co Ltd, classified as an obsolete product. This connector is a straight-through RF coaxial plug designed for RF applications requiring 50-ohm impedance matching. Due to its obsolete status, equivalent substitute parts from the same manufacturer series are necessary to maintain system compatibility and ensure continued availability for replacement and new installations.

Substitute Part Grouping Explanation

The UG-88/U(56) shares the same base product number UG-88/U with its substitute part UG-88/U(41). Substitution is valid based on the following criteria:

• Same manufacturer: Hirose Electric Co Ltd
• Same base product series: UG-88/U
• Same category: Coaxial Connectors (RF)
• Identical functional description: CONN RF COAX PLUG STR
• Matching compliance standards: RoHS Compliant, ECCN EAR99, HTSUS 8536.69.4010
• Active product status of substitute ensures ongoing availability

The numeric suffix variation (56 vs. 41) indicates packaging or configuration variants within the same connector family, with the substitute part UG-88/U(41) maintaining active product status.

Parameter Comparison

Engineering Selection Recommendations

The UG-88/U(41) is the direct substitute for the obsolete UG-88/U(56). Both parts are manufactured by Hirose Electric Co Ltd and share identical electrical and mechanical specifications. The substitute part maintains full RoHS compliance and carries the same ECCN and HTSUS classifications, ensuring regulatory and compliance continuity.

Selection of UG-88/U(41) is supported by its active product status, which guarantees ongoing manufacturing and availability. All critical parameters—impedance, frequency rating, connector type, materials, plating, and operating temperature range—are identical between the two variants. The difference in part number suffix reflects packaging or configuration variants only, with no impact on functional performance or electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can UG-88/U(41) be used as a direct replacement for UG-88/U(56)?

A: Yes. Both parts share the same base product number UG-88/U, identical electrical specifications (50 ohms, 1 GHz maximum frequency), and matching mechanical characteristics (BNC plug, male pin, bayonet lock, free hanging in-line mounting). The numeric suffix variation does not affect functional compatibility.

Q: What is the difference between UG-88/U(56) and UG-88/U(41)?

A: The numeric suffix indicates packaging or configuration variants within the same connector family. All electrical and mechanical parameters are identical. The primary distinction is product status: UG-88/U(56) is obsolete, while UG-88/U(41) is active.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS compliance status, ECCN classification (EAR99), and HTSUS code (8536.69.4010). Regulatory and compliance requirements are fully maintained with the substitute part.

Q: What packaging is available for UG-88/U(41)?

A: UG-88/U(41) is supplied in bulk packaging, as specified by the manufacturer.

Q: Are the material specifications and plating identical?

A: Yes. Both parts use brass body material with nickel finish, brass center contact with gold plating, and PTFE dielectric material. Operating temperature range (-40°C to 85°C) and mating cycle rating (1000 cycles) are identical.
