Phoenix Contact 3003305 Terminal Block Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3003305 is a 2-position feed-through terminal block connector rated for 8-26 AWG wire gauges, with screw termination and polyamide insulation. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new designs. The CLIPLINE UK series connector provides 41 A (IEC) / 50 A (UL) current capacity and 800 V (IEC) / 600 V (UL) voltage rating with UL94 V-0 flammability compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3003305 is determined by strict equivalence across the following critical parameters:

• Electrical Ratings: Current capacity (41 A IEC / 50 A UL) and voltage rating (800 V IEC / 600 V UL) must be maintained or exceeded
• Mechanical Compatibility: Number of positions (2), number of levels (1), terminal width (8.2 mm), and termination style (screw) must be identical
• Wire Gauge Compatibility: Wire gauge range must accommodate 8-26 AWG (0.2-10 mm²)
• Material and Safety Compliance: Polyamide insulation with UL94 V-0 flammability rating required
• Series Alignment: CLIPLINE UK series maintains form factor and mounting compatibility

The Phoenix Contact 3003305 has one manufacturer-recommended substitute: part number 3004524. This substitute maintains all critical electrical, mechanical, and material specifications while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3004524 is the direct equivalent substitute for the obsolete 3003305. Both components share identical electrical ratings, mechanical dimensions, wire gauge compatibility, and material specifications. The 3004524 offers the advantage of active product status, ensuring long-term availability and supply chain continuity.

The 3004524 maintains ROHS3 compliance, which supersedes the RoHS compliance of the original part, providing enhanced environmental and regulatory alignment. The color difference (gray versus orange) is a cosmetic distinction that does not affect electrical or mechanical function.

For applications requiring the original orange color specification, the 3003305 remains available in existing inventory (877 pcs). However, for new designs or long-term production requirements, the 3004524 is the recommended selection due to its active status and superior compliance posture.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3004524 directly replace the 3003305 in existing installations?

A: Yes. The 3004524 maintains identical electrical ratings (41 A IEC / 50 A UL, 800 V IEC / 600 V UL), mechanical dimensions (2 positions, 8.2 mm terminal width), wire gauge compatibility (8-26 AWG), and material specifications (polyamide insulation, UL94 V-0). Direct substitution is electrically and mechanically compatible.

Q: What is the significance of the color difference between the 3003305 (orange) and 3004524 (gray)?

A: Color is a visual identification feature only and does not affect electrical performance, current capacity, voltage rating, or mechanical function. Selection between orange and gray should be based on system documentation or color-coding standards specific to the application.

Q: Why is the 3003305 classified as obsolete?

A: Obsolete status indicates that Phoenix Contact has discontinued active production and support for this part number. The 3004524 serves as the active replacement, ensuring continued availability and manufacturer support.

Q: Are there any compliance differences between the 3003305 and 3004524?

A: Both parts maintain UL94 V-0 flammability compliance and RoHS compliance. The 3004524 carries ROHS3 certification, which represents the current regulatory standard. Both parts are EAR99 classified and share identical HTSUS codes (8536.69.8000).

Q: What packaging options are available for the substitute part?

A: The 3004524 is supplied in bulk packaging. The original 3003305 packaging specification was not provided in the technical data.

Q: Can the 3003305 and 3004524 be used interchangeably in the same circuit design?

A: Yes. Identical electrical ratings, mechanical form factors, and material properties ensure full interchangeability. No circuit redesign or component requalification is required.
