Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 3244135 is determined by the following critical parameters:

• Connector Type & Configuration: Feed-through terminal block with 2 positions, 1 level
• Termination Method: Push-in spring termination
• Electrical Ratings: Minimum 24 A (IEC) / 20 A (UL) current capacity; minimum 800V (IEC) / 600V (UL) voltage rating
• Wire Gauge Compatibility: Support for 12-28 AWG range (0.08-4 mm²)
• Terminal Geometry: 5.2 mm terminal width
• Material & Safety: Polyamide/Nylon insulation with UL94 V-0 flammability rating
• Stripping Length: 8 mm nominal requirement

The Phoenix Contact 1073553 qualifies as a substitute based on matching all critical parameters within acceptable tolerances, with the exception of wire gauge range (12-26 AWG vs. 12-28 AWG) and UL voltage rating (800V vs. 600V), which represent improvements or equivalent performance.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1073553 is a qualified substitute for the 3244135 based on electrical and mechanical parameter alignment. Key considerations:

Advantages of Substitution:

• The 1073553 is in active production status, ensuring long-term availability compared to the Last Time Buy status of the 3244135
• UL voltage rating is improved (800V vs. 600V)
• Stripping length tolerance is broader (8-10 mm vs. 8 mm)
• RoHS compliance is maintained

Limitations of Substitution:

• Wire gauge range is narrower (12-26 AWG vs. 12-28 AWG); applications requiring 28 AWG wire cannot use the substitute
• Minimum wire gauge support is reduced (0.14 mm² vs. 0.08 mm²); applications requiring 0.08 mm² wire cannot use the substitute

Selection of the 1073553 is appropriate for applications within the 12-26 AWG range and 0.14-4 mm² cross-section. Applications requiring 28 AWG or 0.08 mm² wire must retain the original 3244135 or identify alternative sources.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1073553 directly replace the 3244135 in all applications?

A: The 1073553 is compatible with applications using wire gauges 12-26 AWG (0.14-4 mm²). Applications requiring 28 AWG wire or 0.08 mm² cross-section must use the original 3244135 or identify alternative parts.

Q: What is the difference in series between these parts?

A: The 3244135 belongs to the CLIPLINE ST series, while the 1073553 belongs to the CLIPLINE MPT series. Both series use identical push-in spring termination and share the same electrical and mechanical specifications within the overlapping parameter ranges.

Q: Are there any certifications or compliance differences?

A: Both parts are RoHS compliant and carry UL94 V-0 flammability ratings. The 1073553 has a higher UL voltage rating (800V vs. 600V), which does not create compatibility issues for applications rated at 600V or lower.

Q: What should I consider when transitioning from 3244135 to 1073553?

A: Verify that your application wire gauge falls within the 12-26 AWG range and wire cross-section is 0.14 mm² or larger. Confirm that your stripping length can accommodate the 8-10 mm range. If these conditions are met, the 1073553 is a direct functional substitute.

Q: Why is the 3244135 marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. The 1073553 is the recommended active production alternative from Phoenix Contact for this application category.
