Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TA4FB is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Plug, Female Sockets)
• Position count (4 positions)
• Shell size classification (Mini XLR)
• Termination method (Solder)
• Fastening mechanism (Latch Lock)
• Keyed orientation
• Electrical ratings (5A, 125VAC)
• Operating temperature range (-55°C ~ 85°C)
• Cable opening dimensions (0.065" ~ 0.155")
• Shielded configuration
• Integrated features (Backshell, Cable Clamp, Strain Relief)

The TA4FBX meets all substitution criteria as a direct equivalent within the Tini Q-G® connector family, with the distinction of active product status and improved compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The TA4FBX provides direct functional equivalence to the obsolete TA4FB across all electrical, mechanical, and dimensional parameters. The primary distinction lies in product lifecycle status and regulatory compliance. The TA4FBX maintains active product status with Switchcraft Inc., ensuring continued availability and supply chain reliability. Additionally, the TA4FBX achieves ROHS3 compliance, whereas the TA4FB is RoHS non-compliant. Both parts maintain identical REACH and ECCN classifications. For new designs or system upgrades, the TA4FBX is the appropriate selection. For legacy system maintenance requiring exact form-fit-function compatibility, the TA4FBX serves as the direct replacement without modification to existing connector interfaces or cable assemblies.

Frequently Asked Questions (FAQ)

Q: Can the TA4FBX be used as a direct replacement for the TA4FB in existing audio applications?

A: Yes. The TA4FBX is electrically and mechanically equivalent to the TA4FB. Both connectors share identical pin configurations, solder termination, latch lock fastening, keyed orientation, and operating specifications. Existing cable assemblies and mating connectors designed for the TA4FB will function identically with the TA4FBX without modification.

Q: What is the significance of the product status difference between TA4FB and TA4FBX?

A: The TA4FB is classified as obsolete, indicating it is no longer in active production. The TA4FBX maintains active product status, ensuring ongoing manufacturing, quality control, and supply availability. For procurement planning, the TA4FBX represents the current production equivalent.

Q: Are there compliance differences between these two connectors?

A: The TA4FBX achieves ROHS3 compliance, while the TA4FB is RoHS non-compliant. Both maintain identical REACH and ECCN classifications. If regulatory compliance with RoHS3 is a system requirement, the TA4FBX is the appropriate selection.

Q: Do the TA4FB and TA4FBX have different packaging options?

A: The TA4FB packaging specification is not provided. The TA4FBX is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are the electrical ratings identical between TA4FB and TA4FBX?

A: Yes. Both connectors are rated for 5A at 125VAC with operating temperature range of -55°C to 85°C. Cable opening dimensions are identical at 0.065" to 0.155" (1.65mm to 3.94mm).
