Equivalent & Substitute Parts for A-1JB-100

Part Overview

The A-1JB-100 is a U.FL (UMCC) AMC Connector Jack with male pin configuration, rated for 50 Ohms impedance and designed for surface mount solder termination. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts to maintain design continuity and ensure procurement availability. The part operates across a frequency range up to 6 GHz and is suitable for RF applications requiring compact coaxial connectivity.

Substitute Part Grouping Explanation

Substitution of the A-1JB-100 is determined by strict equivalence across the following critical parameters: connector style (U.FL/UMCC), impedance (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).

The substitute parts are grouped into two categories:

Parametric Equivalent (Same Connector Type - Jack): Part A-1JB maintains identical electrical and mechanical specifications as the main part, with the distinction of active product status and improved compliance certification (ROHS3 versus RoHS3 Compliant). This part is a direct functional replacement.

Direct Substitutes (Receptacle Configuration): Parts 0734120110 (Molex) and U.FL-R-SMT-1(10) (Hirose Electric Co Ltd) are receptacle-type connectors that mate with jack-type connectors. These parts satisfy the same electrical parameters (50 Ohms, 6 GHz, surface mount solder termination) and mechanical constraints (snap-on fastening, 30 mating cycles, -40°C to 90°C operation). The receptacle configuration represents a complementary connector type within the U.FL/UMCC standard, suitable for applications requiring the mating half of the connector pair.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Connector Type): Part A-1JB is the primary substitute for A-1JB-100. Both components maintain identical electrical and mechanical specifications across all critical parameters. The A-1JB offers the advantage of active product status, ensuring long-term procurement availability and supply chain stability. Additionally, A-1JB carries ROHS3 compliance certification, representing current regulatory alignment compared to the obsolete A-1JB-100.

For Complementary Connector Applications: Parts 0734120110 (Molex) and U.FL-R-SMT-1(10) (Hirose Electric Co Ltd) serve as receptacle-type substitutes. These components are appropriate for applications requiring the mating connector half. Both parts maintain full electrical equivalence (50 Ohms, 6 GHz operation) and mechanical compatibility (surface mount, snap-on fastening, 30 mating cycles). Both substitute parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.

Selection between the Molex and Hirose receptacle options depends on secondary specifications not provided in the core parameters, such as housing color preference (silver for Molex, beige for Hirose) and body material finish (nickel for Molex, silver for Hirose).

Frequently Asked Questions (FAQ)

Q: Can A-1JB be used as a direct replacement for A-1JB-100?

A: Yes. A-1JB is a parametric equivalent with identical electrical and mechanical specifications. The primary distinction is product status: A-1JB is active while A-1JB-100 is obsolete. A-1JB also carries ROHS3 compliance certification.

Q: What is the difference between the jack connector (A-1JB-100) and the receptacle connectors (0734120110, U.FL-R-SMT-1(10))?

A: The A-1JB-100 is a jack-type connector with a male pin, while 0734120110 and U.FL-R-SMT-1(10) are receptacle-type connectors. These connector types are complementary and mate together. Both types satisfy identical electrical parameters (50 Ohms, 6 GHz) and mechanical requirements (surface mount, snap-on fastening).

Q: Are all substitute parts compliant with current regulations?

A: Yes. All substitute parts (A-1JB, 0734120110, and U.FL-R-SMT-1(10)) carry ROHS3 compliance certification and REACH Unaffected status, meeting current regulatory requirements.

Q: What are the packaging options for substitute parts?

A: A-1JB is available in Cut Tape (CT) and Digi-Reel® packaging. Part 0734120110 is available in Cut Tape (CT) and Digi-Reel® packaging. Part U.FL-R-SMT-1(10) is available in Cut Tape (CT) packaging.

Q: Do all parts operate across the same temperature range?

A: Yes. The main part A-1JB-100 and all substitute parts operate across the identical temperature range of -40°C to 90°C.

Q: Are the mating cycle ratings identical across all parts?

A: Yes. The A-1JB-100 and all substitute parts are rated for 30 mating cycles.

Q: What is the impedance specification for all parts?

A: All parts, including the main component and all substitutes, are rated for 50 Ohms impedance, suitable for standard RF applications.

Q: Can these connectors be used interchangeably in the same circuit?

A: The jack-type connector (A-1JB-100 or A-1JB) and receptacle-type connectors (0734120110 or U.FL-R-SMT-1(10)) are complementary components designed to mate together. They cannot be used interchangeably in the same position; rather, they are used as mating pairs in RF circuit designs.
