Key Parameters

Substitute Part Grouping Explanation

The TA3MLBX qualifies as a direct substitute for the TA3MLB based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Identical connector type (Receptacle, Male Pins)
• Identical number of positions (3)
• Identical shell size (Mini XLR)
• Identical termination method (Solder)
• Identical fastening type (Latch Lock)
• Identical current and voltage ratings (5A, 125VAC)
• Identical operating temperature range (-55°C ~ 85°C)
• Identical cable opening specifications (0.115" ~ 0.190")
• Identical shielding configuration (Shielded)

The TA3MLBX is part of the Tini Q-G® TA-X series and maintains full electrical and mechanical compatibility with the original TA3MLB specification.

Parameter Comparison

Engineering Selection Recommendations

The TA3MLBX is the direct substitute for the obsolete TA3MLB. Both parts maintain identical electrical and mechanical specifications for Mini XLR 3-position circular connector applications.

The primary distinction between the two parts is product status and regulatory compliance. The TA3MLBX is currently in active production status, whereas the TA3MLB is obsolete. The TA3MLBX also carries ROHS3 compliance certification, compared to the non-compliant status of the original TA3MLB. This compliance improvement makes the TA3MLBX the preferred choice for new designs and ongoing component sourcing.

For applications requiring the exact electrical and mechanical interface of the TA3MLB, the TA3MLBX provides full compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the TA3MLBX be used as a direct replacement for the TA3MLB?

A: Yes. The TA3MLBX maintains identical electrical ratings (5A, 125VAC), mechanical configuration (3-position Mini XLR, solder termination), operating temperature range (-55°C ~ 85°C), and cable opening specifications (0.115" ~ 0.190"). No circuit or mechanical redesign is required.

Q: What is the primary advantage of selecting the TA3MLBX over the TA3MLB?

A: The TA3MLBX is in active production status and carries ROHS3 compliance certification. The TA3MLB is obsolete and RoHS non-compliant. For new designs and long-term component availability, the TA3MLBX is the appropriate selection.

Q: Are there packaging differences between these parts?

A: The TA3MLBX is supplied in bulk packaging. The original TA3MLB packaging specification is not provided in the technical data. Confirm packaging requirements with your procurement department.

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

A: Yes. Both the TA3MLB and TA3MLBX accommodate cable diameters from 0.115" to 0.190" (2.92mm to 4.83mm).

Q: Are the contact and shell materials identical?

A: Yes. Both parts feature copper alloy shells with chrome finish and copper alloy contacts with silver finish. Insert material is polyphenylene sulfide (PPS) in both cases.
