ATB6 Terminal Block Connector Equivalent & Substitute Parts

Part Overview

The ATB6 is a 2-position feed-through terminal block connector manufactured by Amphenol PCD, designed for wire gauges 8-22 AWG with screw termination. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations. The ATB6 operates at 41 A (IEC) / 50 A (UL) and 800V (IEC) / 600V (UL), with polyamide insulation suitable for industrial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATB6 is determined by strict equivalence across the following critical parameters:

• Number of positions: 2
• Number of levels: 1
• Terminal width: 8.0 mm
• Termination style: Screw
• Wire gauge range: 8-22 AWG (1.5-6 mm²)
• Current rating (IEC): 41 A minimum
• Voltage rating (IEC): 800 V minimum
• Current rating (UL): 50 A minimum
• Voltage rating (UL): 600 V minimum
• Insulation material: Polyamide (PA66), Nylon 6/6
• Stripping length: 12 mm
• RoHS compliance: Required

The ATX6F meets all specified electrical, mechanical, and material requirements for direct substitution. Differences in color, packaging format, and product status do not affect functional compatibility within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

The ATX6F is a direct functional equivalent to the ATB6 across all critical electrical and mechanical parameters. The ATX6F is classified as active product status, ensuring ongoing availability and manufacturer support, whereas the ATB6 is obsolete. Both components maintain identical current and voltage ratings under IEC and UL standards, identical wire gauge compatibility, and identical insulation material specifications.

The ATX6F is supplied in tray packaging and features orange insulation coloring, compared to the ATB6's gray coloring. These differences are cosmetic and do not affect electrical performance or mechanical compatibility. The ATX6F's active product status makes it the preferred selection for new designs and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can ATX6F replace ATB6 in existing installations?

A: Yes. The ATX6F meets all electrical, mechanical, and material specifications of the ATB6. Identical current ratings (41 A IEC / 50 A UL), voltage ratings (800 V IEC / 600 V UL), wire gauge range (8-22 AWG), terminal width (8.0 mm), and screw termination style ensure direct functional compatibility.

Q: Does the color difference between ATB6 (gray) and ATX6F (orange) affect compatibility?

A: No. Color is a cosmetic parameter and does not affect electrical performance, mechanical fit, or functional operation. Selection should be based on system documentation and color-coding requirements.

Q: What is the significance of ATB6 being obsolete?

A: Obsolete status indicates the ATB6 is no longer manufactured. The ATX6F, classified as active, is the current production equivalent and is recommended for all new designs and ongoing procurement.

Q: Are both components RoHS compliant?

A: Yes. Both ATB6 and ATX6F are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: Does packaging format affect electrical performance?

A: No. The ATX6F is supplied in tray packaging while the ATB6 packaging format is not specified. Packaging affects logistics and handling only; electrical and mechanical performance remain identical.
