Switchcraft TA4F Mini XLR 4-Position Circular Connector Plug

Part Overview

The Switchcraft TA4F is a 4-position circular connector plug with female sockets designed for solder termination in audio applications. This connector features a Mini XLR shell size with keyed orientation, shielded construction, and integrated backshell with cable clamp and strain relief. The TA4F is classified as obsolete product status, making identification of equivalent and substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Switchcraft TA4F are identified based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

Critical Matching Parameters:

• Connector type: Plug with female sockets
• Number of positions: 4
• Shell size: Mini XLR
• Fastening type: Latch Lock
• Orientation: Keyed
• Current rating: 5A minimum
• Operating temperature range: Must encompass or match -55°C ~ 85°C
• Termination method: Solder or solder cup

Substitute Parts Identified:

1. TA4FX (Switchcraft Inc.) — Direct manufacturer evolution. Identical electrical and mechanical specifications with active product status and RoHS3 compliance.

2. AG4F (Amphenol Audio) — Cross-manufacturer equivalent. Meets all critical mechanical and electrical parameters with Mini XLR G Type™ series compatibility. Operates within acceptable temperature range (-30°C ~ 80°C) and maintains 5A current rating.

Parameter Comparison

Engineering Selection Recommendations

TA4FX (Switchcraft Inc.) is the primary recommended substitute for the obsolete TA4F. This part maintains identical electrical and mechanical specifications while offering active product status and RoHS3 compliance. The TA4FX is the direct evolution within the Switchcraft product line, ensuring design continuity and supply chain stability.

AG4F (Amphenol Audio) serves as a secondary cross-manufacturer alternative when TA4FX availability is constrained. The AG4F maintains mechanical compatibility and electrical performance within acceptable parameters. Design considerations include:

• Operating temperature range of -30°C ~ 80°C (versus TA4F specification of -55°C ~ 85°C) — suitable for applications not requiring full temperature extremes
• Unshielded construction versus shielded TA4F — appropriate for non-EMI-sensitive audio applications
• Gold contact finish versus silver — provides enhanced corrosion resistance in certain environmental conditions
• Solder cup termination versus solder — accommodates alternative assembly methods

Both substitute parts carry RoHS3 compliance and active product status, supporting modern procurement and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can TA4FX directly replace TA4F without design modification?

A: Yes. The TA4FX maintains identical pin configuration, shell size, keyed orientation, and electrical ratings (5A, 125VAC). Mechanical and electrical compatibility is complete. The primary difference is product status (active versus obsolete) and RoHS compliance.

Q: What are the key differences between TA4FX and AG4F?

A: Both parts share 4-position Mini XLR configuration and 5A current rating. Differences include: TA4FX is shielded with silver contacts and -55°C ~ 85°C operating range; AG4F is unshielded with gold contacts and -30°C ~ 80°C operating range. TA4FX uses solder termination; AG4F uses solder cup. Shell material differs (copper alloy versus brass).

Q: Is AG4F suitable for applications requiring shielding?

A: No. The AG4F is unshielded, making it unsuitable for applications requiring electromagnetic interference protection. The TA4FX maintains the shielded construction of the original TA4F.

Q: What is the cable opening compatibility between TA4F and substitutes?

A: TA4F and TA4FX both accept cable diameters of 0.065" ~ 0.155" (1.65mm ~ 3.94mm). AG4F accepts 0.138" (4.60mm) cable diameter. Cable diameter must fall within the specified range for proper strain relief and backshell engagement.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both TA4FX and AG4F are RoHS3 compliant, whereas the original TA4F is RoHS non-compliant. This supports modern procurement standards and regulatory requirements.

Q: What termination method differences exist between the parts?

A: TA4F and TA4FX use solder termination (direct solder to PCB pads). AG4F uses solder cup termination (wire inserted into cup, then soldered). Both methods are compatible with standard assembly processes; selection depends on existing assembly infrastructure.

Q: Can TA4F be used in applications with operating temperatures below -30°C?

A: TA4F and TA4FX both support -55°C ~ 85°C operating range. AG4F supports only -30°C ~ 80°C. For applications requiring sub-30°C operation, TA4FX is the appropriate choice.
