Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 3029680 is determined by the following critical parameters:

• Number of Positions: Must be 4
• Terminal Width: Must be 10.4mm
• Mounting Type: Must be Direct Mount
• Termination Style: Must be Push In, Spring
• Type: Must be Middle
• Physical Dimensions: Length 1.260" (32.00mm) and Height (Max) 0.866" (22.00mm)
• Material & Flammability: Polyamide (PA), Nylon insulation with UL94 V-0 rating
• Electrical Performance: Current and voltage ratings must meet or exceed IEC 17.5A at 800V
• Wire Gauge Compatibility: Must accommodate the required wire range

The Phoenix Contact 3244258 qualifies as a substitute based on these parameters. While it belongs to the CLIPLINE ST series (versus CLIPLINE MZDB), it maintains identical mechanical form factor, mounting configuration, and exceeds the electrical performance requirements of the original part.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3244258 is a qualified substitute for the 3029680 based on the following engineering criteria:

Mechanical Compatibility: Both parts share identical form factors, mounting configurations, and physical dimensions, ensuring direct replacement capability in existing PCB layouts and mechanical assemblies.

Electrical Performance: The 3244258 exceeds the electrical specifications of the original part, providing 24A at 800V (IEC) compared to 17.5A at 800V. This enhanced current capacity ensures compatibility with applications requiring the original part's performance envelope.

Wire Gauge Range: The substitute accommodates a broader wire gauge range (12-28 AWG / 0.08-4mm²) compared to the original (14-26 AWG / 0.14-2.5mm²), providing greater flexibility for wire selection while maintaining compatibility with the original specification range.

Regulatory Compliance: Both parts maintain UL94 V-0 flammability ratings and polyamide insulation materials. The 3244258 carries ROHS3 compliance, representing current regulatory alignment compared to the original RoHS Compliant designation.

Product Status Consideration: The 3244258 is designated Last Time Buy, indicating limited future availability. Procurement planning should account for this status when establishing long-term supply strategies.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3244258 directly replace the 3029680 in existing designs?

A: Yes. Both parts maintain identical mechanical form factors, mounting types, and physical dimensions (1.260" length, 0.866" maximum height). The 4-position, 10.4mm terminal width configuration is identical, enabling direct substitution in PCB layouts and mechanical assemblies.

Q: What are the key electrical differences between these parts?

A: The 3244258 provides enhanced electrical performance with 24A at 800V (IEC) versus the original 17.5A at 800V (IEC). Both maintain 800V voltage ratings. The substitute also includes UL ratings (20A at 600V), whereas the original part does not specify UL performance.

Q: Are there wire gauge compatibility considerations?

A: The 3244258 accommodates a broader wire gauge range (12-28 AWG / 0.08-4mm²) compared to the 3029680 (14-26 AWG / 0.14-2.5mm²). Applications using the original part's wire range remain fully compatible with the substitute.

Q: Does the housing color difference affect functionality?

A: No. The 3029680 features green and yellow housing, while the 3244258 is gray. Housing color is a visual identification feature and does not impact electrical or mechanical performance. Color selection should be based on system documentation and assembly requirements.

Q: What is the significance of the series difference (CLIPLINE MZDB versus CLIPLINE ST)?

A: Series designation indicates product line evolution within Phoenix Contact's terminal block portfolio. Both series employ identical push-in spring termination technology and maintain compatible mechanical and electrical specifications for this application class.

Q: Are there compliance differences between these parts?

A: Both parts maintain UL94 V-0 flammability ratings and polyamide insulation. The 3244258 carries ROHS3 compliance, representing alignment with current regulatory requirements. The original part is RoHS Compliant. Both are suitable for applications requiring these certifications.

Q: Should the Last Time Buy status of the 3244258 influence selection decisions?

A: Yes. The Last Time Buy designation indicates limited future availability of the 3244258. Long-term supply planning should account for this status when establishing procurement strategies for ongoing production or maintenance requirements.
