TA5MB Circular Connector Equivalent & Substitute Parts

Part Overview

The TA5MB is a 5-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 solder termination with integrated backshell, cable clamp, and strain relief features. The TA5MB is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the TA5MB is determined by strict equivalence across the following critical parameters:

Connector configuration: 5-position receptacle with male pins, Mini XLR shell size, keyed orientation Electrical specifications: 4A current rating, 125VAC voltage rating, shielded design Mechanical compatibility: Solder termination, latch lock fastening, free hanging in-line mounting Environmental performance: Operating temperature range -55°C ~ 85°C, cable opening 0.065" ~ 0.155" Material and construction: Copper alloy shell with chrome finish, copper alloy contacts with silver finish, PPS insert material, UL94 V-0 flammability rating

The TA5MBX meets all these criteria and is identified as a direct substitute for the obsolete TA5MB.

Engineering Selection Recommendations

The TA5MBX is the direct substitute for the obsolete TA5MB. Both components maintain identical electrical, mechanical, and environmental specifications across all critical parameters. The primary distinction is product status: TA5MB is obsolete while TA5MBX is active and currently manufactured.

The TA5MBX offers improved regulatory compliance. It meets ROHS3 requirements, whereas the TA5MB is RoHS non-compliant. This compliance improvement makes TA5MBX the preferred selection for new designs and systems requiring adherence to current environmental regulations. The MSL rating of 1 (Unlimited) for TA5MBX indicates superior moisture handling characteristics compared to the TA5MB.

For applications currently using TA5MB, direct substitution with TA5MBX is supported without modification to circuit design, PCB layout, or mechanical assembly procedures. Connector pinout, mating interface, and electrical performance remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can TA5MBX be used as a direct replacement for TA5MB in existing assemblies?

A: Yes. The TA5MBX is electrically and mechanically equivalent to TA5MB across all functional parameters. Pinout, mating interface, current and voltage ratings, operating temperature range, and mechanical mounting are identical. No circuit or assembly modifications are required.

Q: What is the significance of the TA5MBX being ROHS3 compliant while TA5MB is not?

A: ROHS3 compliance indicates the TA5MBX meets current environmental regulations restricting hazardous substances in electrical and electronic equipment. For new system designs or procurement in regulated markets, TA5MBX is the appropriate selection. Existing systems using TA5MB may continue operation without regulatory impact unless subject to specific compliance mandates.

Q: Are there differences in packaging between TA5MB and TA5MBX?

A: TA5MB packaging is not specified in available documentation. TA5MBX is supplied in bulk packaging. Confirm packaging requirements with your procurement specification before ordering.

Q: What does the MSL rating difference indicate?

A: TA5MBX carries an MSL rating of 1 (Unlimited), meaning it has no moisture sensitivity limitations and does not require special storage or handling conditions. TA5MB lists MSL as Not Applicable. The TA5MBX rating provides greater flexibility in storage and handling environments.

Q: Are both parts suitable for audio applications?

A: Yes. Both TA5MB and TA5MBX are specified for audio applications. The 5-position Mini XLR configuration, shielded design, and solder termination are standard for professional audio signal transmission.

Q: What is the difference between the TA and TA-X series designations?

A: TA5MB belongs to the Tini Q-G® TA series, while TA5MBX belongs to the Tini Q-G® TA-X series. Both series share identical connector specifications. The series designation change reflects manufacturing evolution and regulatory updates, with TA-X representing the current active production line.
