TA4MB Circular Connector Receptacle - Equivalent & Substitute Parts

Part Overview

The TA4MB is a 4-position circular connector receptacle with male pins, manufactured by Switchcraft Inc. as part of the Tini Q-G® TA series. This connector is designed for audio applications requiring solder termination with integrated strain relief and cable management features. The TA4MB is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TA4MB is determined by strict equivalence across the following critical parameters:

• Connector type and pin configuration (Receptacle, Male Pins, 4-position)
• Physical form factor (Mini XLR shell size)
• Electrical ratings (5A current, 125VAC voltage)
• Termination method (Solder)
• Mechanical interface (Latch Lock fastening, Keyed orientation)
• Environmental specifications (Operating temperature -55°C ~ 85°C)
• Material composition and finishes (Copper alloy shell and contacts with specified plating)

The TA4MBX qualifies as a direct substitute based on complete alignment with these parameters. Both parts maintain identical electrical and mechanical specifications, with the primary distinction being product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The TA4MBX is the direct substitute for the obsolete TA4MB. Both parts are electrically and mechanically equivalent across all specified parameters. The TA4MBX offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the TA4MBX achieves ROHS3 compliance, whereas the TA4MB is non-compliant with RoHS regulations. For new designs or system upgrades, the TA4MBX is the appropriate selection. For legacy system maintenance requiring exact part matching, the TA4MB remains functionally identical where available inventory permits.

Frequently Asked Questions (FAQ)

Q: Can TA4MBX be used as a direct replacement for TA4MB in existing assemblies?

A: Yes. The TA4MBX is electrically and mechanically equivalent to the TA4MB. Both parts share identical connector type, pin configuration, electrical ratings, termination method, and physical form factor. No circuit modifications or mechanical redesign is required.

Q: What is the primary difference between TA4MB and TA4MBX?

A: The TA4MB is classified as obsolete, while the TA4MBX is an active product. The TA4MBX also achieves ROHS3 compliance, whereas the TA4MB does not. Functionally, both parts are equivalent.

Q: Are there packaging differences between these parts?

A: The TA4MB is supplied in standard packaging, while the TA4MBX is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact electrical or mechanical performance.

Q: What cable gauges are compatible with these connectors?

A: Both the TA4MB and TA4MBX accommodate cable openings ranging from 0.065" to 0.155" (1.65mm to 3.94mm), supporting standard audio cable gauges used in professional applications.

Q: Are these connectors suitable for high-temperature applications?

A: Both parts operate within the temperature range of -55°C to 85°C. Applications requiring operation outside this range require alternative connector selection.

Q: What is the current-carrying capacity of these connectors?

A: Both the TA4MB and TA4MBX are rated for 5A continuous current at 125VAC, suitable for standard audio signal distribution and low-power control applications.
