TA4FLB Equivalent & Substitute Parts

Part Overview

The TA4FLB is a 4-position circular connector plug with female sockets manufactured by Switchcraft Inc. as part of the Tini Q-G® TA series. This Mini XLR connector is designed for audio applications with solder termination, featuring a shielded design rated for 5A at 125VAC. The TA4FLB is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The TA4FLBX qualifies as a direct substitute for the TA4FLB based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector type remains Plug, Female Sockets
• Number of positions is 4
• Shell size is Mini XLR
• Termination method is Solder
• Fastening type is Latch Lock
• Keyed orientation is maintained
• Current rating of 5A is supported
• Voltage rating of 125VAC is supported
• Cable opening range of 0.115" ~ 0.190" (2.92mm ~ 4.83mm) is compatible
• Operating temperature range of -55°C ~ 85°C is maintained
• Shielded design with backshell and cable clamp features is preserved

The TA4FLBX is part of the Tini Q-G® TA-X series and maintains full electrical and mechanical compatibility with the original TA4FLB specification.

Parameter Comparison

Engineering Selection Recommendations

The TA4FLBX is the direct substitute for the obsolete TA4FLB. Both connectors maintain identical electrical and mechanical specifications for audio applications. The primary distinction is product status: the TA4FLB is obsolete while the TA4FLBX is active and currently available.

For new designs or component replacement, the TA4FLBX is the appropriate selection. The TA4FLBX offers the additional advantage of ROHS3 compliance, whereas the TA4FLB is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the TA4FLBX directly replace the TA4FLB in existing assemblies?

A: Yes. The TA4FLBX maintains full electrical and mechanical compatibility with the TA4FLB. All critical parameters including connector type, position count, shell size, termination method, current and voltage ratings, operating temperature range, and cable opening specifications are identical.

Q: What is the primary reason to substitute the TA4FLB?

A: The TA4FLB is classified as obsolete. The TA4FLBX is the active equivalent part from Switchcraft Inc. and is the recommended selection for ongoing procurement and new applications.

Q: Are there packaging differences between these parts?

A: The TA4FLB packaging is listed as unspecified. The TA4FLBX is supplied in Bulk packaging. Both parts are available in new original condition.

Q: Do these connectors have different compliance certifications?

A: The TA4FLBX is ROHS3 compliant, while the TA4FLB is RoHS non-compliant. Both maintain REACH Unaffected status and EAR99 export classification.

Q: Are the solder termination specifications identical?

A: Yes. Both the TA4FLB and TA4FLBX use solder termination with identical contact material (Copper Alloy) and insert material (Thermoplastic). The cable opening range of 0.115" ~ 0.190" (2.92mm ~ 4.83mm) is the same for both parts.

Q: What is the operating temperature range for these connectors?

A: Both the TA4FLB and TA4FLBX operate across the temperature range of -55°C to 85°C.
