Key Parameters

Substitute Part Grouping Explanation

The TA4MLBX qualifies as a direct substitute for the TA4MLB based on matching electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Identical connector type (Receptacle, Male Pins)
• Matching position count (4 positions)
• Same shell size designation (Mini XLR)
• Identical termination method (Solder)
• Matching fastening mechanism (Latch Lock)
• Equivalent electrical ratings (5A current, 125VAC voltage)
• Identical operating temperature range (-55°C ~ 85°C)
• Matching shielding configuration (Shielded)
• Compatible cable opening specifications (0.115" ~ 0.190")

The TA4MLBX represents an active product variant within the Tini Q-G® series, specifically the TA-X line, providing functional continuity for applications previously served by the obsolete TA4MLB.

Parameter Comparison

Engineering Selection Recommendations

The TA4MLBX is the appropriate selection for applications currently using or requiring TA4MLB functionality. The substitute part maintains full electrical and mechanical compatibility while offering the advantage of active product status and ROHS3 compliance. The TA4MLBX eliminates obsolescence risk associated with the TA4MLB and aligns with current regulatory requirements for restricted substances.

For new designs or system upgrades, the TA4MLBX should be specified to ensure long-term component availability and compliance with environmental standards.

Frequently Asked Questions (FAQ)

Q: Can TA4MLBX directly replace TA4MLB in existing assemblies?

A: Yes. The TA4MLBX maintains identical electrical ratings (5A, 125VAC), mechanical dimensions, connector configuration (4-position Mini XLR receptacle with male pins), and termination method (solder). Physical form factor and pin assignment are equivalent.

Q: What is the primary difference between TA4MLB and TA4MLBX?

A: The TA4MLBX is the active production variant of the TA4MLB series. Key differences include product status (Active vs. Obsolete), RoHS compliance (ROHS3 Compliant vs. non-compliant), and moisture sensitivity rating (1 Unlimited vs. Not Applicable). Electrical and mechanical specifications remain identical.

Q: Are there packaging differences between these parts?

A: The TA4MLB is supplied in standard packaging, while the TA4MLBX is available in bulk packaging. This distinction does not affect component functionality or compatibility.

Q: Why should I transition from TA4MLB to TA4MLBX?

A: The TA4MLB is obsolete, creating procurement risk and potential supply discontinuation. The TA4MLBX provides equivalent functionality with active product status, ensuring ongoing availability and compliance with ROHS3 environmental regulations.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across the identical temperature range of -55°C to 85°C, ensuring thermal compatibility in equivalent applications.
