Phoenix Contact 3073678 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3073678 is a 1-position terminal block with bolt/screw clamp wire entry at 90° to the panel, rated for 600V UL and 65A current. This component is part of the CLIPLINE RW series and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for maintenance and new installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3073678 is based on the following critical parameters that must remain consistent:

• Electrical Ratings: Voltage (600V UL) and current capacity (65A) must be maintained
• Mechanical Configuration: 1 position per level, 2-piece panel mount type, bolt/screw clamp connection with 90° wire entry
• Wire Connection Method: Bolt/screw clamp at both front and rear panel
• Color: Gray
• Compliance: RoHS compliance status

The substitute part Phoenix Contact 0709864 meets these core substitution criteria while offering an active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 0709864 is a direct functional substitute for the obsolete 3073678. Both components maintain identical electrical ratings (600V UL, 65A) and mechanical configuration (1 position, 2-piece panel mount, bolt/screw clamp connection). The substitute part offers the advantage of active product status, ensuring long-term availability and supply chain continuity.

The 0709864 features improved compliance with ROHS3 certification and REACH unaffected status, meeting current regulatory requirements. The reduced width (0.398" versus 0.642") and narrower panel thickness range (1.0 ~ 4.0mm versus 1.0 ~ 6.0mm) should be verified against specific panel mounting requirements in your application.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 0709864 directly replace 3073678 in existing installations?

A: Yes, the 0709864 maintains the same electrical ratings (600V UL, 65A), mechanical configuration (1 position, 2-piece panel mount), and wire connection method (bolt/screw clamp at 90° to panel). Physical dimensions differ; verify that the reduced width (10.10mm versus 16.30mm) and panel thickness range (1.0 ~ 4.0mm versus 1.0 ~ 6.0mm) are compatible with your panel mounting specifications.

Q: What is the primary reason for substitution?

A: The 3073678 is classified as obsolete. The 0709864 is an active product from Phoenix Contact, providing assured supply availability and current compliance certifications.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant. The 0709864 offers ROHS3 compliance and REACH unaffected status, representing current regulatory alignment.

Q: What wire gauge does the substitute part support?

A: The 0709864 supports 6-24 AWG wire gauge. Wire gauge specifications for the original 3073678 were not provided.

Q: Are there packaging differences?

A: The 3073678 packaging type was not specified. The 0709864 is supplied in bulk packaging.
