Phoenix Contact 3003839 Terminal Block Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3003839 is a 4-position terminal block from the CLIPLINE MZDB series, designed for direct mount applications with push-in spring termination. This middle-type terminal block operates at 17.5 A (IEC) and 800 V (IEC), supporting wire gauges from 14-26 AWG (0.14-2.5 mm²). The product is classified as obsolete, necessitating identification of equivalent substitute components for ongoing system maintenance and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 3003839 are identified based on functional equivalence within the allowed parameter ranges for terminal block applications. The critical parameters determining substitution compatibility are:

• Number of positions: 4
• Terminal type: Middle
• Mounting type: Direct Mount
• Termination style: Push In, Spring
• Housing color: Gray
• Material composition: Polyamide (PA), Nylon
• Flammability rating: UL94 V-0
• Physical dimensions: Length 32.00 mm, Height 22.00 mm

The substitute parts 3244232 and 3244258 maintain these core functional and physical characteristics. Both are from the CLIPLINE ST series and support the same 4-position, single-level configuration with identical housing color and material specifications. While the terminal width differs (10.4 mm versus 16.2 mm), both substitute parts operate within acceptable electrical parameters for their respective wire gauge ranges and maintain compliance with applicable standards.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 3244232 and 3244258 are functionally equivalent to the Phoenix Contact 3003839 for applications requiring 4-position terminal blocks with push-in spring termination and gray polyamide housing.

The substitute parts offer enhanced electrical performance with 24 A (IEC) current ratings compared to the main part's 17.5 A rating, while maintaining the same 800 V voltage specification. The expanded wire gauge range (12-28 AWG, 0.08-4 mm²) provides greater flexibility for conductor accommodation compared to the main part's 14-26 AWG range.

Both substitute parts carry ROHS3 compliance status, representing current regulatory alignment. The main part's RoHS Compliant designation reflects earlier compliance documentation. Both substitute parts are classified as Last Time Buy, indicating limited availability windows for procurement planning.

The 10.4 mm terminal width of the substitute parts differs from the main part's 16.2 mm specification. This dimensional change does not affect functional compatibility for standard terminal block applications but requires verification of physical space constraints within the target assembly.

Frequently Asked Questions (FAQ)

Q: Can parts 3244232 and 3244258 directly replace the Phoenix Contact 3003839?

A: Both substitute parts maintain functional equivalence through identical position count, termination style, voltage rating, housing material, and flammability rating. The primary dimensional difference is terminal width (10.4 mm versus 16.2 mm). Direct replacement is feasible for applications where the reduced terminal width does not conflict with PCB layout or mechanical constraints.

Q: What is the difference between parts 3244232 and 3244258?

A: Both parts share identical electrical specifications, wire gauge ranges, physical dimensions, and material composition. They are both from the CLIPLINE ST series and carry Last Time Buy status. No functional distinction exists between these two part numbers for terminal block applications.

Q: Why does the main part 3003839 have a lower current rating than the substitutes?

A: The 17.5 A (IEC) rating of the main part reflects the CLIPLINE MZDB series design specifications. The substitute parts from the CLIPLINE ST series are rated at 24 A (IEC), representing a different product line with enhanced electrical capacity. Both ratings are valid for their respective series and applications.

Q: Are there compatibility concerns with the expanded wire gauge range of the substitute parts?

A: The substitute parts accommodate wire gauges from 12-28 AWG (0.08-4 mm²), compared to the main part's 14-26 AWG range. This expanded range provides greater flexibility. Applications using wire gauges within the main part's original range remain fully compatible with the substitute parts.

Q: What is the significance of the Last Time Buy status for the substitute parts?

A: Last Time Buy status indicates limited remaining availability for procurement. For applications requiring long-term component supply, this status should be considered in inventory planning and design lifecycle decisions.

Q: Do the substitute parts meet the same compliance standards as the main part?

A: Both substitute parts maintain UL94 V-0 flammability rating and carry ROHS3 compliance, which supersedes the main part's RoHS Compliant designation. Both parts are suitable for applications requiring these certifications.
