ATB2 Terminal Block Connector - Equivalent & Substitute Parts

Part Overview

The ATB2 is a 2-position feed-through terminal block connector manufactured by Amphenol PCD, designed for screw termination of 14-24 AWG wire. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The ATB2 operates at 24 A (IEC) / 20 A (UL) and 800V (IEC) / 600V (UL), with gray polyamide insulation and a 5.0mm terminal width.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATB2 is determined by the following critical parameters:

• Electrical Performance: Current and voltage ratings must meet or exceed IEC and UL specifications (24 A / 800V IEC minimum; 20 A / 600V UL minimum)
• Physical Configuration: 2-position, 1-level feed-through design with screw termination
• Wire Compatibility: Wire gauge range must accommodate 14-24 AWG (0.5-2.5mm²) applications
• Terminal Geometry: Terminal width and mechanical fit within the 5.0mm specification envelope
• Material & Compliance: Polyamide insulation with RoHS compliance required

The Phoenix Contact 3001501 qualifies as a substitute based on matching electrical ratings, feed-through configuration, 2-position design, screw termination, and RoHS compliance. The 3001501 accepts a broader wire gauge range (12-28 AWG / 0.2-4mm²), which encompasses the ATB2 specification and provides additional flexibility for wire selection.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3001501 is a suitable substitute for the obsolete ATB2 based on the following criteria:

Electrical Equivalence: Both components maintain identical IEC and UL current and voltage ratings (24 A / 800V IEC; 20 A / 600V UL), ensuring no derating is required in existing circuit designs.

Functional Compatibility: Both are 2-position, 1-level feed-through terminal blocks with screw termination, providing direct functional replacement in applications requiring this configuration.

Wire Gauge Accommodation: The 3001501 wire gauge range (12-28 AWG / 0.2-4mm²) fully encompasses the ATB2 specification (14-24 AWG / 0.5-2.5mm²), allowing use in all applications originally designed for the ATB2.

Regulatory Compliance: Both components are RoHS compliant. The 3001501 carries ROHS3 certification, meeting current regulatory requirements. Both are REACH Unaffected and classified as EAR99 for export control purposes.

Product Availability: The 3001501 is actively manufactured by Phoenix Contact, ensuring long-term supply continuity compared to the obsolete ATB2.

Minor Dimensional Variance: The terminal width difference (5.0mm vs. 5.2mm) represents a 0.2mm increase and does not preclude mechanical compatibility in standard mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3001501 directly replace the ATB2 in existing designs?

A: Yes. The 3001501 matches all critical electrical parameters (current, voltage, IEC/UL ratings) and functional configuration (2-position, feed-through, screw termination). The wire gauge range of the 3001501 fully encompasses ATB2 specifications, and both use compatible polyamide insulation materials.

Q: What is the significance of the wire gauge range difference?

A: The ATB2 accepts 14-24 AWG wire, while the 3001501 accepts 12-28 AWG. This means the 3001501 can accommodate all wire sizes originally specified for the ATB2, plus additional smaller and larger gauges. No wire gauge compatibility issues exist when substituting the 3001501 for the ATB2.

Q: Does the 0.2mm terminal width difference affect mechanical fit?

A: The terminal width increase from 5.0mm to 5.2mm is minor and does not affect standard mounting or connector interface compatibility. Both components are designed for screw termination in similar form factors.

Q: Are there compliance or regulatory differences between these parts?

A: Both components are RoHS compliant and REACH Unaffected. The 3001501 carries ROHS3 certification, which represents the current regulatory standard. Both are classified as EAR99 for export control purposes, indicating no additional export restrictions apply.

Q: Why is the ATB2 listed as obsolete?

A: The ATB2 is no longer manufactured by Amphenol PCD. The Phoenix Contact 3001501 is an actively produced alternative that meets all functional and electrical requirements of the ATB2, making it the appropriate substitute for new designs and ongoing maintenance applications.

Q: What is the stripping length difference between these parts?

A: The ATB2 specifies 9mm stripping length, while the 3001501 specifies 8mm. This 1mm difference is within standard wire preparation tolerances and does not affect termination quality or electrical performance.
