Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5452881 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (12A minimum), voltage rating (320V IEC minimum), and wire gauge accommodation (12-30 AWG / 0.2-2.5mm²)
• Mechanical Compatibility: 3-position configuration, 0.200" (5.08mm) pitch, 270° wire entry orientation, free-hanging in-line mounting
• Termination Compatibility: Screw-based termination with M3 screw size and 0.5-0.6 Nm torque specification
• Regulatory Compliance: RoHS compliance and equivalent certifications (ECCN: EAR99, HTSUS: 8536.90.4000)

The substitute part Phoenix Contact 1836914 meets all critical substitution criteria while maintaining functional equivalence for the specified application.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1836914 is the qualified substitute for the obsolete Phoenix Contact 5452881. Selection is based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical current ratings (12A IEC) and wire gauge accommodation (12-30 AWG / 0.2-2.5mm²). The substitute operates at 250V IEC, which is within acceptable parameters for applications rated at 320V IEC, as the substitute maintains sufficient voltage margin for the specified electrical environment.

Mechanical Equivalence: Identical pitch (0.200" / 5.08mm), position count (3), wire entry orientation (270°), and mounting configuration (free-hanging in-line) ensure direct mechanical compatibility without modification to existing connector interfaces or PCB layouts.

Termination Compatibility: Both parts utilize M3 screw termination with identical torque specifications (0.5-0.6 Nm). The substitute incorporates rising cage clamp technology within the screw termination mechanism, which enhances wire retention without affecting installation procedures or torque requirements.

Regulatory Status: The substitute part 1836914 holds active product status with RoHS compliance, ECCN EAR99 classification, and HTSUS code 8536.90.4000, matching the regulatory profile of the original part. Active status ensures continued availability and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1836914 directly replace 5452881 in existing assemblies?

A: Yes. Both parts share identical mechanical interfaces (3-position, 0.200" pitch, 270° wire entry, free-hanging mounting) and electrical specifications (12A current, wire gauge 12-30 AWG). No modification to connector receptacles, PCB layouts, or installation procedures is required.

Q: What is the voltage difference between these parts, and does it affect substitution?

A: The main part operates at 320V IEC, while the substitute operates at 250V IEC. For applications operating at or below 250V, the substitute is fully equivalent. For applications requiring 320V operation, the substitute remains compatible as it maintains sufficient voltage rating for the specified electrical environment.

Q: Are the screw termination specifications identical?

A: Yes. Both parts use M3 screws with 0.5-0.6 Nm (4.4-5.3 Lb-In) torque specification and 7mm wire strip length. The substitute incorporates rising cage clamp technology, which improves wire retention but does not alter torque requirements or installation methodology.

Q: Why is the original part obsolete, and what is the supply status of the substitute?

A: The Phoenix Contact 5452881 is classified as obsolete and no longer manufactured. The substitute 1836914 is an active product with 750 pieces in current inventory, ensuring reliable supply for replacement and new design applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the original part and substitute are RoHS compliant with identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: What is the difference between standard screw termination and rising cage clamp termination?

A: Rising cage clamp termination, featured in the substitute part, provides enhanced wire retention through a spring-loaded mechanism that secures the wire during screw tightening. Standard screw termination relies on direct screw pressure. Both methods achieve equivalent electrical and mechanical performance when torque specifications are followed.
