JBX1CTMC07 Equivalent & Substitute Parts Reference

Part Overview

The JBX1CTMC07 is a pin contact for circular connectors manufactured by Souriau-Sunbank by Eaton. This component is designed for signal applications in the JBX series and features a 0.7mm contact size with crimp termination for wire gauges 22-26 AWG. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where JBX series components are specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the JBX1CTMC07 is based on the following critical parameters that must align for functional equivalence:

Primary Compatibility Criteria:

• Contact type: Pin (signal application)
• Contact termination method: Crimp
• Contact finish: Gold plating
• Moisture sensitivity level: MSL 1 or equivalent
• RoHS compliance: ROHS3 or equivalent

Secondary Consideration:

• Wire gauge compatibility within acceptable overlap ranges
• Contact size tolerance relative to connector cavity specifications

The substitute part FGG.0B.560.ZZC from PEI-Genesis meets these criteria with the following relationship: while the contact size differs (0.9mm vs. 0.7mm), the wire gauge ranges overlap in the 22-24 AWG region, and both components share identical termination method, finish type, and compliance certifications. This overlap permits substitution in applications where the connector cavity accommodates the larger contact size.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution Consideration:

The FGG.0B.560.ZZC contact is suitable as a substitute for the JBX1CTMC07 based on the following factors:

1. Termination Compatibility: Both components use crimp termination, ensuring compatibility with existing crimping equipment and processes.

2. Electrical Properties: Both contacts feature gold plating for signal integrity and corrosion resistance. The substitute provides increased plating thickness (39.4µin vs. 19.7µin), which enhances durability.

3. Wire Gauge Overlap: The wire gauge ranges overlap at 22-24 AWG, providing a functional window for substitution within this range.

4. Product Status: The substitute part is active and in stock (964 pcs), whereas the main part is obsolete, making the substitute the practical choice for new procurement.

5. Compliance: The main part is ROHS3 compliant. Compliance status for the substitute should be confirmed with the manufacturer prior to final selection.

Critical Limitation:

The contact size difference (0.7mm vs. 0.9mm) requires verification that the receiving connector cavity is designed to accommodate the larger 0.9mm contact. Physical compatibility with the mating connector must be confirmed before implementation.

Frequently Asked Questions (FAQ)

Q: Can the FGG.0B.560.ZZC be used as a direct replacement for the JBX1CTMC07?

A: Substitution is possible only if the receiving connector cavity is designed for 0.9mm contacts. The larger contact size is the primary constraint. Both components share crimp termination, gold finish, and overlapping wire gauge specifications (22-24 AWG), which support functional equivalence within this wire gauge range.

Q: What is the significance of the contact size difference?

A: Contact size (0.7mm vs. 0.9mm) determines physical fit within the connector cavity. A 0.9mm contact cannot be inserted into a cavity designed for 0.7mm contacts. Connector specifications must be reviewed to confirm cavity size compatibility.

Q: Are the crimp termination processes identical?

A: Both components use crimp termination, indicating compatibility with standard crimp tooling. However, the different contact sizes may require different crimp die specifications. Tooling compatibility should be verified with the equipment manufacturer.

Q: What is the impact of the different gold plating thicknesses?

A: The substitute part features double the plating thickness (39.4µin vs. 19.7µin). This provides enhanced corrosion resistance and extended contact life, representing an improvement over the original specification.

Q: Is the substitute part RoHS compliant?

A: RoHS compliance status for the FGG.0B.560.ZZC is not specified in the provided data. Confirmation of ROHS3 compliance should be obtained from PEI-Genesis before final selection if RoHS compliance is a system requirement.

Q: What wire gauges are suitable for substitution?

A: The overlapping wire gauge range is 22-24 AWG. The JBX1CTMC07 supports 22-26 AWG, while the FGG.0B.560.ZZC supports 20-24 AWG. Substitution is limited to the 22-24 AWG overlap range.

Q: How does the packaging differ?

A: The main part packaging is not specified, while the substitute is supplied in bulk packaging. Bulk packaging may require internal repackaging for inventory management depending on organizational requirements.
