Engineering Selection Recommendations

The Phoenix Contact 1835229 is the direct substitute for the obsolete 5451323. Both components maintain identical electrical specifications (12A IEC, 630V IEC) and mechanical interfaces (15 positions, 0.200" pitch, 90° wire entry, M3 screw termination). The 1835229 offers enhanced UL current rating (15A versus 12A) and rising cage clamp termination technology, providing improved performance margins without compromising compatibility.

The 1835229 carries active product status with full manufacturer support, RoHS compliance, and UL94 V-0 flammability certification, making it the preferred choice for new designs and replacement applications. Both components support identical wire gauge ranges (12-30 AWG / 0.2-2.5mm²) and operate within the same torque specification (0.5-0.6 Nm).

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1835229 directly replace the 5451323 in existing installations?

A: Yes. The 1835229 maintains full mechanical and electrical compatibility with the 5451323. Both components feature 15 positions at 0.200" (5.08mm) pitch, identical wire entry angle (90°), equivalent current and voltage ratings (IEC specifications), and matching M3 screw termination with identical torque requirements (0.5-0.6 Nm).

Q: What is the difference in termination technology between these parts?

A: The 5451323 uses standard screw termination, while the 1835229 incorporates rising cage clamp technology. Both accept the same wire gauge range (12-30 AWG / 0.2-2.5mm²) and maintain identical torque specifications. The rising cage clamp design in the 1835229 provides enhanced contact reliability without requiring interface modifications.

Q: Are there packaging differences between these components?

A: The 5451323 is supplied in standard packaging, while the 1835229 is available in bulk packaging. This distinction affects procurement and inventory management but does not impact electrical or mechanical performance.

Q: Does the 1835229 meet the same compliance standards as the 5451323?

A: Yes. Both components are RoHS compliant, carry UL94 V-0 flammability ratings, and meet identical IEC electrical specifications (12A, 630V). The 1835229 additionally provides enhanced UL current rating (15A versus 12A), exceeding the original specification.

Q: What wire gauges are supported by the substitute part?

A: The 1835229 supports the same wire gauge range as the 5451323: 12-30 AWG (0.2-2.5mm²). Wire strip length is identical at 7mm for both components.
