TA4FL Equivalent & Substitute Parts

Part Overview

The TA4FL 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, free-hanging mounting, and shielded construction. The TA4FL is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations where this connector type is required.

Substitute Part Grouping Explanation

Substitute parts for the TA4FL are qualified based on the following critical parameters that ensure functional and mechanical compatibility:

Connector Type & Position Count: Both substitutes maintain plug configuration with female sockets and 4-position design
Shell Size & Interface: Mini XLR shell size ensures mechanical fit with mating receptacles
Electrical Ratings: 5A current and 125VAC voltage ratings are maintained across all variants
Termination & Mounting: Solder termination and free-hanging mounting configuration remain consistent
Operating Environment: Temperature range (-55°C ~ 85°C) and cable opening specifications (0.115" ~ 0.190") are preserved
Shielding & Contact Materials: Shielded construction with copper alloy contacts and silver mating finish are standard across all parts

The TA4FLBX and TA4FLX are direct functional equivalents with active product status, differing only in shell finish (chrome vs. nickel) and RoHS compliance status, both of which are allowable variations within the Mini XLR 4-position connector category.

Engineering Selection Recommendations

TA4FLBX is recommended for applications requiring RoHS3 compliance with chrome shell finish. This part is actively manufactured and available in bulk packaging with 820 units in stock. The chrome finish provides enhanced corrosion resistance compared to nickel plating.

TA4FLX is recommended for applications requiring RoHS3 compliance with nickel shell finish, maintaining the original finish specification of the TA4FL. This part is actively manufactured with the highest inventory availability (5003 units in stock) and offers the closest material and finish match to the obsolete TA4FL.

Both substitute parts are functionally equivalent to the TA4FL across all critical electrical and mechanical parameters. Selection between TA4FLBX and TA4FLX should be based on shell finish requirements and RoHS compliance mandates for the end application.

Frequently Asked Questions (FAQ)

Q: Can TA4FLBX and TA4FLX be used interchangeably with TA4FL?

A: Yes. Both parts maintain identical electrical ratings (5A, 125VAC), mechanical configuration (4-position Mini XLR plug with female sockets), operating temperature range (-55°C ~ 85°C), and cable opening specifications (0.115" ~ 0.190"). The only differences are shell finish (chrome vs. nickel) and RoHS compliance status, which do not affect functional compatibility in the connector interface.

Q: What is the difference between TA4FLBX and TA4FLX?

A: The primary difference is shell finish: TA4FLBX features chrome plating while TA4FLX features nickel plating. Both are ROHS3 compliant and actively manufactured. TA4FLX has higher inventory availability and matches the original nickel finish of the TA4FL.

Q: Why is the TA4FL obsolete?

A: The TA4FL is classified as obsolete by the manufacturer. The active equivalents TA4FLBX and TA4FLX from the Tini Q-G® TA-X series provide continued availability for this connector type.

Q: Are there packaging differences between these parts?

A: The TA4FL packaging is not specified in available data. Both TA4FLBX and TA4FLX are supplied in bulk packaging, which is standard for solder-terminated connectors.

Q: Do these connectors meet current compliance standards?

A: TA4FLBX and TA4FLX are ROHS3 compliant and REACH unaffected. The obsolete TA4FL is RoHS non-compliant. For new designs or systems with RoHS requirements, TA4FLBX or TA4FLX must be specified.
