Phoenix Contact 3244313 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3244313 is a 4-position feed-through terminal block connector designed for wire gauges 12-28 AWG with push-in spring termination. This component is classified as Last Time Buy, indicating discontinued production status. The CLIPLINE ST series offers compact connectivity solutions with UL94 V-0 rated polyamide insulation suitable for industrial control and distribution applications.

Identifying equivalent and substitute parts is necessary due to the Last Time Buy status of the original component. Alternative models from the same manufacturer provide functional compatibility while ensuring continued supply chain access and compliance with current product availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Phoenix Contact 3244313 is determined by the following critical parameters:

Core Functional Parameters:

• Number of positions: 4
• Number of levels: 1
• Termination style: Push In, Spring
• Wire gauge compatibility: 12-28 AWG minimum overlap
• Electrical ratings: Current and voltage ratings must meet or exceed IEC/UL specifications
• Insulation material and flammability rating: UL94 V-0 polyamide

Physical Compatibility Parameters:

• Terminal width tolerance: ±0.3 mm acceptable variance
• Stripping length: 8-10 mm range
• Color: Blue housing

Compliance Parameters:

• RoHS compliance status
• Flammability certification: UL94 V-0

The Phoenix Contact 1429439 qualifies as a substitute based on matching core functional parameters: 4-position configuration, 1-level design, push-in spring termination, overlapping wire gauge range (12-26 AWG covers the primary 12-28 AWG range), equivalent electrical ratings, identical insulation material and flammability rating, and RoHS compliance. Minor variations in terminal width (10.3 mm vs. 10.4 mm) and stripping length range (8-10 mm vs. 8 mm) remain within acceptable engineering tolerances for feed-through terminal block applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1429439 is a qualified substitute for the 3244313 based on functional and compliance equivalence. Both components share identical electrical ratings (24 A IEC, 20 A UL), voltage specifications (800 V IEC, with the substitute exceeding the 600 V UL requirement), termination methodology, and insulation certification (UL94 V-0).

The primary consideration for substitution is wire gauge compatibility. The original 3244313 supports 12-28 AWG, while the 1429439 supports 12-26 AWG. Applications utilizing 28 AWG conductors require evaluation of alternative solutions. For applications within the 12-26 AWG range, the 1429439 provides equivalent performance with the advantage of active product status and continued manufacturing availability.

The 1429439 is classified as Active product status, ensuring long-term supply chain stability compared to the Last Time Buy status of the original component. Both components maintain RoHS compliance and identical flammability certification, supporting regulatory requirements across industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1429439 directly replace the 3244313 in all applications?

A: Direct replacement is applicable for applications using wire gauges 12-26 AWG. Applications requiring 28 AWG conductor support must identify alternative components, as the 1429439 does not support this gauge.

Q: What is the significance of the terminal width difference (10.4 mm vs. 10.3 mm)?

A: The 0.1 mm variance is within standard manufacturing tolerances for terminal block connectors and does not affect functional compatibility or mechanical fit in standard DIN rail mounting configurations.

Q: Does the 1429439 meet the same electrical specifications as the 3244313?

A: Yes. Both components are rated for 24 A at 800 V (IEC) and 20 A at 600 V (UL). The 1429439 exceeds the UL voltage requirement at 800 V, providing additional margin.

Q: Why does the 1429439 have a stripping length range (8-10 mm) instead of a fixed specification (8 mm)?

A: The range specification provides installation flexibility while maintaining electrical and mechanical performance. The original 8 mm specification falls within this range and remains compatible.

Q: Are there any compliance or certification differences between these components?

A: Both components are RoHS compliant and carry UL94 V-0 flammability certification. No compliance differences exist between the two parts.

Q: What is the impact of the wire gauge range difference (0.08-4 mm² vs. 0.14-4 mm²)?

A: The 1429439 minimum of 0.14 mm² corresponds to approximately 26 AWG. Applications using conductors smaller than 0.14 mm² (28 AWG and finer) cannot use the 1429439 and require alternative components.

Q: Is the 1429439 available in the same packaging as the 3244313?

A: The 1429439 is available in bulk packaging. Specific packaging configurations should be confirmed with the supplier based on application requirements.
