Phoenix Contact 3029648 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3029648 is a 4-position terminal block from the CLIPLINE MZDB series, designed for direct mount applications with push-in spring termination. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The terminal block accommodates wire gauges from 14-26 AWG (0.14-2.5mm²) and operates within IEC ratings of 17.5 A at 800 V.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3029648 is based on the following critical parameters that must remain consistent or be enhanced:

• Mechanical Compatibility: 4-position configuration, 10.4mm terminal width, middle type, direct mount, gray housing
• Electrical Performance: IEC voltage rating of 800 V minimum; current rating must meet or exceed 17.5 A (IEC)
• Termination Method: Push-in spring termination required
• Wire Accommodation: Wire gauge range must encompass or exceed 14-26 AWG (0.14-2.5mm²)
• Material & Compliance: Polyamide insulation with UL94 V-0 flammability rating; RoHS compliance required

The Phoenix Contact 3244258 qualifies as a substitute based on these parameters. While it belongs to the CLIPLINE ST series (Last Time Buy status), it maintains mechanical interchangeability and exceeds electrical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3244258 is a direct substitute for the obsolete 3029648. The substitute part maintains identical mechanical dimensions and mounting characteristics while providing enhanced electrical performance. Current capacity increases from 17.5 A to 24 A (IEC) and from 15 A to 20 A (UL), and wire gauge accommodation expands from 14-26 AWG to 12-28 AWG. Both parts meet UL94 V-0 flammability requirements and maintain 800 V IEC voltage ratings.

The 3244258 carries Last Time Buy status, indicating limited future availability. Both parts are RoHS and REACH compliant, with the substitute meeting ROHS3 specifications. Mechanical interchangeability is confirmed through identical terminal width (10.4mm), position count (4), length (32.00mm), and height (22.00mm).

Frequently Asked Questions (FAQ)

Q: Can the 3244258 be used as a direct replacement for the 3029648?

A: Yes. Both parts share identical mechanical dimensions, terminal configuration, and mounting type. The 3244258 provides equal or superior electrical performance across all ratings.

Q: What are the key differences between these parts?

A: The primary differences are series designation (CLIPLINE MZDB vs. CLIPLINE ST), product status (Obsolete vs. Last Time Buy), and enhanced electrical specifications in the 3244258. Current capacity increases by 6.5 A (IEC) and wire gauge range expands to accommodate smaller and larger conductors.

Q: Are there any compatibility concerns with wire gauge differences?

A: No. The 3244258 accommodates a broader wire gauge range (12-28 AWG vs. 14-26 AWG), ensuring compatibility with applications using the original part's wire specifications while supporting additional conductor sizes.

Q: What is the significance of the product status change?

A: The original 3029648 is obsolete and no longer manufactured. The 3244258 is Last Time Buy, meaning Phoenix Contact will fulfill existing orders but will not continue production beyond a specified date. Long-term availability planning is recommended.

Q: Do both parts meet current compliance standards?

A: Yes. Both parts are RoHS compliant and REACH unaffected. The 3244258 meets the more recent ROHS3 specification, ensuring compliance with current regulatory requirements.
