Equivalent & Substitute Parts for A-1JB-500 Coaxial Connector

Part Overview

The A-1JB-500 is a U.FL (UMCC) AMC Connector Jack with male pin configuration, rated for 50 Ohms impedance and designed for surface mount solder termination. Manufactured by Amphenol RF, this component operates across a frequency range up to 6 GHz and is classified as obsolete. Due to its obsolete product status, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. The substitute parts listed maintain functional compatibility through matching electrical and mechanical specifications while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-1JB-500 is determined by the following critical parameters: connector style (U.FL/UMCC), impedance rating (50 Ohms), mounting type (surface mount), contact and shield termination method (solder), frequency capability (6 GHz maximum), operating temperature range (-40°C to 90°C), and mating cycle rating (30 cycles). All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional compatibility within the same application context. The substitute parts are grouped into two categories: parametric equivalents from the same manufacturer series and direct manufacturer alternatives from different suppliers that meet identical performance criteria.

Parameter Comparison

Engineering Selection Recommendations

The A-1JB from Amphenol RF serves as the primary parametric equivalent, offering identical electrical and mechanical specifications while maintaining active product status and improved inventory availability. This part is recommended as the first-choice substitute due to manufacturer continuity and series compatibility within the AMC connector family.

The 0734120110 from Molex and U.FL-R-SMT-1(10) from Hirose Electric Co Ltd are direct manufacturer alternatives that satisfy all core electrical and mechanical requirements. Both parts are classified as active products with ROHS3 compliance, exceeding the RoHS compliance level of the original part. Selection between these alternatives depends on supply chain considerations, packaging preferences, and existing vendor relationships.

All substitute parts maintain compliance with REACH regulations and carry unlimited moisture sensitivity level ratings, ensuring suitability for standard manufacturing and storage environments. The voltage rating differential between the main part (500 V) and substitute parts (60 V) does not affect substitution eligibility, as the lower rating remains adequate for typical RF connector applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the A-1JB be used as a direct replacement for the A-1JB-500?

A: Yes. The A-1JB maintains identical electrical specifications (50 Ohms impedance, 6 GHz frequency capability, -40°C to 90°C operating range) and mechanical configuration (surface mount solder termination, snap-on fastening, single port). The primary difference is product status; the A-1JB is active while the A-1JB-500 is obsolete. Both parts are manufactured by Amphenol RF within the AMC connector series.

Q: What is the difference between the Amphenol RF A-1JB and the Molex 0734120110?

A: Both parts are U.FL (UMCC) connectors with 50 Ohms impedance, surface mount solder termination, and 6 GHz frequency capability. The primary differences are manufacturer identity and connector type designation: the A-1JB is classified as a Jack with Male Pin, while the 0734120110 is classified as a Receptacle with Male Pin. Both are functionally compatible within the same application context and meet identical electrical performance criteria.

Q: Are there packaging differences between substitute parts?

A: Yes. The A-1JB is available in Cut Tape (CT) and Digi-Reel® packaging. The 0734120110 is supplied in Cut Tape (CT) and Digi-Reel® packaging. The U.FL-R-SMT-1(10) is available in Cut Tape (CT) packaging. Selection should account for production volume requirements and existing assembly line compatibility.

Q: Do all substitute parts meet current compliance standards?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original A-1JB-500 carries RoHS compliance (non-3 designation), while all active substitutes carry ROHS3 compliance, representing an improvement in regulatory alignment.

Q: What is the significance of the voltage rating difference?

A: The A-1JB-500 carries a 500 V voltage rating, while substitute parts carry 60 V ratings. For RF connector applications operating within the specified frequency range and impedance parameters, the 60 V rating of substitute parts is adequate. Voltage rating does not determine RF connector substitution eligibility when impedance, frequency, and termination specifications are matched.

Q: Can these parts be used interchangeably in existing designs?

A: Substitution is permissible when the design accommodates the connector type designation (Jack versus Receptacle) and packaging format. All parts maintain identical electrical performance across the 6 GHz frequency range and -40°C to 90°C operating temperature window. Physical layout and mating interface compatibility must be verified during design review.
