TA3MB Equivalent & Substitute Parts

Part Overview

The TA3MB is a 3-position circular connector receptacle with male pins, manufactured by Switchcraft Inc. as part of the Tini Q-G® TA series. This component is designed for audio applications requiring shielded connections with solder termination. The TA3MB is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Substitute Part Grouping Explanation

Substitution eligibility for the TA3MB is determined by strict equivalence across the following critical parameters:

Connector type and pin configuration (Receptacle, Male Pins, 3-position)
Shell size and insert type (Mini XLR)
Termination method (Solder)
Fastening mechanism (Latch Lock)
Keyed orientation for polarization
Electrical ratings (5A current, 125VAC voltage)
Operating temperature range (-55°C ~ 85°C)
Shielding requirement (Shielded)
Cable opening dimensions (0.065" ~ 0.155")

The TA3MBX meets all these criteria and is therefore a direct substitute for the TA3MB.

Engineering Selection Recommendations

The TA3MBX is the direct substitute for the TA3MB. Both components share identical electrical, mechanical, and functional specifications across all critical parameters. The primary distinction is product status: the TA3MB is obsolete while the TA3MBX is active and currently manufactured.

For new designs and ongoing production requiring Mini XLR 3-position male pin receptacles with solder termination, the TA3MBX is the appropriate selection. The TA3MBX offers the additional advantage of ROHS3 compliance, whereas the TA3MB is RoHS non-compliant. Both components maintain equivalent performance in audio applications within the specified operating temperature and electrical rating parameters.

Frequently Asked Questions (FAQ)

Q: Can the TA3MBX directly replace the TA3MB in existing assemblies?

A: Yes. The TA3MBX is a direct substitute with identical connector type, pin configuration, shell size, termination method, and electrical ratings. Physical dimensions and mating characteristics are equivalent.

Q: What is the primary reason to transition from TA3MB to TA3MBX?

A: The TA3MB is classified as obsolete. The TA3MBX is the active equivalent from Switchcraft Inc., ensuring continued availability and supply chain reliability. Additionally, the TA3MBX meets ROHS3 compliance requirements.

Q: Are there packaging differences between these parts?

A: The TA3MB packaging is listed as unspecified, while the TA3MBX is supplied in bulk packaging. This distinction does not affect functional compatibility or performance.

Q: Do both parts support the same cable opening dimensions?

A: Yes. Both the TA3MB and TA3MBX accommodate cable openings of 0.065" ~ 0.155" (1.65mm ~ 3.94mm).

Q: Are the operating temperature ranges identical?

A: Yes. Both components operate across the range of -55°C ~ 85°C.

Q: What are the electrical specifications for both parts?

A: Both the TA3MB and TA3MBX are rated for 5A current and 125VAC voltage, with shielded construction suitable for audio applications.
