Substitute Part Grouping Explanation

The TA3FLBX qualifies as a direct substitute for the TA3FLB based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

Connector type and gender match (Plug, Female Sockets)
Position count is identical (3 positions)
Shell size and insert type are identical (Mini XLR)
Termination method is identical (Solder)
Fastening mechanism is identical (Latch Lock)
Keyed orientation is maintained
Current and voltage ratings are equal or exceed requirements (5A, 125VAC)
Operating temperature range encompasses or matches the original (-55°C ~ 85°C)
Cable opening specifications are identical (0.115" ~ 0.190")
Shielding configuration is identical (Shielded)

The TA3FLBX represents an active product variant within the Tini Q-G® series, offering improved compliance status while maintaining full electrical and mechanical compatibility.

Engineering Selection Recommendations

The TA3FLBX is the direct equivalent for the obsolete TA3FLB. Selection of the TA3FLBX is appropriate for new designs and replacement applications due to its active product status and ROHS3 compliance. The TA3FLB remains suitable for existing systems where component replacement is not required, though long-term availability is limited due to obsolescence.

For applications subject to RoHS3 regulatory requirements, the TA3FLBX is the required selection. Both parts maintain identical electrical performance, mechanical fit, and audio application suitability.

Frequently Asked Questions (FAQ)

Q: Can TA3FLBX replace TA3FLB in existing assemblies?

A: Yes. The TA3FLBX maintains identical connector type, position count, shell size, termination method, fastening mechanism, electrical ratings, and operating temperature range. Physical and electrical compatibility is complete.

Q: What is the primary difference between TA3FLB and TA3FLBX?

A: The TA3FLBX is an active product with ROHS3 compliance, while the TA3FLB is obsolete and RoHS non-compliant. Both parts are electrically and mechanically identical.

Q: Are there packaging differences between these parts?

A: The TA3FLB packaging is not specified. The TA3FLBX is supplied in bulk packaging.

Q: What applications are these connectors suitable for?

A: Both parts are specified for audio applications requiring 3-position Mini XLR female socket plugs with solder termination.

Q: What is the current and voltage capacity of these connectors?

A: Both parts are rated for 5A current and 125VAC voltage.

Q: What is the operating temperature range?

A: Both parts operate across -55°C to 85°C.
