Engineering Selection Recommendations
The Phoenix Contact 1835122 is a qualified substitute for the obsolete 5451226 based on the following engineering criteria:
Electrical Equivalence: Both parts maintain identical IEC ratings (12A at 630V) and UL voltage specifications (300V). The 1835122 provides enhanced UL current capacity (15A versus 12A), representing a performance improvement without introducing incompatibility.
Mechanical Compatibility: Identical pitch (5.08mm), wire entry angle (90°), mounting configuration (free-hanging in-line), and screw specifications (M3, 0.5-0.6 Nm torque) ensure direct mechanical interchangeability.
Compliance & Safety: Both parts meet UL94 V-0 flammability requirements, MSL 1 environmental classification, and tin contact mating finish specifications. The 1835122 carries ROHS3 compliance, representing current regulatory alignment compared to the obsolete part's RoHS compliance status.
Termination Enhancement: The 1835122 incorporates rising cage clamp termination technology, providing improved wire retention and contact reliability compared to standard screw termination, while maintaining identical torque specifications and wire gauge acceptance.
Frequently Asked Questions (FAQ)
Q: Can the 1835122 directly replace the 5451226 in existing applications?
A: Yes. Both parts share identical connector pitch (5.08mm), position count (5), wire entry angle (90°), mounting type (free-hanging in-line), and electrical ratings (12A at 630V IEC). Mechanical and electrical interchangeability is confirmed.
Q: What is the primary difference between these two parts?
A: The 1835122 uses rising cage clamp termination versus the 5451226's standard screw termination. Both maintain identical M3 screw specifications and torque requirements (0.5-0.6 Nm). The 1835122 also offers enhanced UL current rating (15A versus 12A) and current regulatory compliance (ROHS3).
Q: Are there packaging differences between these parts?
A: The 5451226 is listed with unspecified packaging, while the 1835122 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact functional or electrical compatibility.
Q: Do both parts accept the same wire gauge range?
A: Yes. Both the 5451226 and 1835122 accommodate 12-30 AWG wire (0.2-2.5mm²) and require identical torque specifications for screw termination.
Q: Is the 1835122 suitable for applications requiring 630V IEC rating?
A: Yes. The 1835122 maintains the full 630V IEC voltage rating, matching the original 5451226 specification.
