Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3029651 is determined by strict alignment of electrical and mechanical parameters. The substitute part Phoenix Contact 3244041 qualifies based on the following criteria:

Critical Matching Parameters:

• Manufacturer: Phoenix Contact (same manufacturer ensures design compatibility)
• Number of Positions: 2 (identical configuration)
• Number of Levels: 1 (identical configuration)
• Terminal Width: 5.2mm (identical mechanical interface)
• Termination Style: Push In, Spring (identical connection method)
• Mounting Type: Direct Mount (identical installation method)
• Material - Insulation: Polyamide (PA), Nylon (identical material composition)
• Material Flammability Rating: UL94 V-0 (identical safety rating)
• Length: 1.260" (32.00mm) (identical physical dimension)
• Height (Max): 0.866" (22.00mm) (identical physical dimension)

Electrical Parameter Compatibility: The substitute part 3244041 meets or exceeds the electrical requirements of the original part across both IEC and UL standards, with higher current ratings (24A IEC / 20A UL versus 17.5A IEC / 15A UL) and identical voltage ratings (800V IEC / 600V UL).

Wire Gauge Compatibility: The substitute part accommodates an expanded wire gauge range (12-28 AWG / 0.08-4mm²) that fully encompasses the original part's range (14-26 AWG / 0.14-2.5mm²).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3244041 is a direct functional substitute for the obsolete 3029651 terminal block. Both components share identical mechanical interfaces, mounting configurations, and core electrical specifications. The substitute part offers enhanced electrical performance with higher current ratings under both IEC and UL standards while maintaining voltage compatibility.

The 3244041 is classified as Last Time Buy status, indicating limited availability. Both parts maintain equivalent RoHS compliance and flammability ratings (UL94 V-0), ensuring regulatory alignment in applications requiring these certifications. The expanded wire gauge range of the substitute part provides additional design flexibility without compromising compatibility with the original part's specified wire sizes.

The primary difference in housing color (blue versus gray) is cosmetic and does not affect electrical or mechanical function. The minor variation in stripping length (9mm versus 8mm) reflects series design differences but does not impact terminal block operation within specified parameters.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 3244041 directly replace 3029651 in existing applications?

A: Yes. Both parts share identical mechanical interfaces (5.2mm terminal width, 2-position configuration, direct mount), identical termination methods (push-in spring), and equivalent electrical ratings. The substitute part meets or exceeds all electrical specifications of the original.

Q: What is the significance of the different series designations (CLIPLINE MZB versus CLIPLINE ST)?

A: Series designation indicates design generation within Phoenix Contact's terminal block product line. Both series employ identical mechanical and electrical standards for this configuration, ensuring functional compatibility.

Q: Does the housing color difference (blue versus gray) affect compatibility?

A: No. Housing color is a cosmetic attribute and does not affect electrical performance, mechanical fit, or functional operation.

Q: Why does the substitute part have a different stripping length specification?

A: Stripping length reflects design optimization within each series. The 8mm specification for 3244041 versus 9mm for 3029651 is a series-specific parameter that does not impact terminal block function when used within specified wire gauge ranges.

Q: Are both parts RoHS compliant?

A: Yes. The original part 3029651 is RoHS Compliant, and the substitute part 3244041 is ROHS3 Compliant, both meeting current regulatory requirements.

Q: What wire gauges are compatible with the substitute part?

A: The 3244041 accommodates 12-28 AWG (0.08-4mm²), which fully encompasses the original part's range of 14-26 AWG (0.14-2.5mm²). Applications using the original part's wire gauge specifications will operate within the substitute part's rated range.

Q: What is the current rating difference between the two parts?

A: The substitute part 3244041 provides higher current capacity: 24A at 800V (IEC) and 20A at 600V (UL), compared to the original part's 17.5A at 800V (IEC) and 15A at 600V (UL). This represents an enhancement that does not compromise backward compatibility.
