Engineering Selection Recommendations

Phoenix Contact 1792854 is the qualified substitute for the obsolete 5451488. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity. Both parts maintain identical IEC electrical ratings (12A, 630V) and UL94 V-0 flammability compliance. The substitute achieves higher UL current rating (15A versus 12A), providing enhanced electrical capacity within the same physical and mechanical envelope.

The substitute incorporates rising cage clamp termination technology in addition to screw termination, offering improved wire retention characteristics. Both parts comply with RoHS directives (the substitute meets ROHS3 specification), and both are classified as MSL 1 (Unlimited moisture sensitivity level).

For applications requiring the exact original screw-only termination without cage clamp features, the 5451488 specifications must be cross-referenced with current Phoenix Contact product lines. However, the 1792854 substitute provides direct functional equivalence with enhanced reliability features and active product status.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1792854 directly replace 5451488 in existing installations?

A: Yes. Both parts share identical pitch (5.08mm), position count (12), wire entry angle (270°), mounting configuration (free-hanging in-line), wire gauge range (12-30 AWG), screw size (M3), and torque specifications (0.5-0.6 Nm). Electrical ratings are equivalent at IEC levels (12A, 630V). The substitute maintains UL94 V-0 flammability compliance and identical housing material (polyamide nylon).

Q: What is the difference in termination style between the two parts?

A: The 5451488 uses screw termination only. The 1792854 substitute uses screw termination with rising cage clamp technology. The cage clamp feature provides additional wire retention without affecting screw-based installation procedures. Both parts accept identical wire gauges and torque specifications.

Q: Are there packaging differences between these parts?

A: The 5451488 is supplied in standard packaging (not specified). The 1792854 substitute is supplied in bulk packaging. Both parts are available in new original condition with current inventory levels (1055 pcs and 1173 pcs respectively).

Q: Does the substitute part meet current compliance requirements?

A: Yes. The 1792854 substitute meets ROHS3 compliance (enhanced RoHS specification) compared to the original RoHS Compliant status of 5451488. Both parts are classified as MSL 1 (Unlimited) and carry identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: What is the UL current rating difference?

A: The 5451488 is rated at 12A (UL). The 1792854 substitute is rated at 15A (UL). Both maintain 300V (UL) voltage rating. The higher UL current capacity of the substitute does not affect compatibility in applications designed for 12A operation.
