Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5452849 is determined by strict alignment of the following critical parameters:

Core Compatibility Criteria:

• 9-position configuration with 0.150" (3.81mm) pitch spacing
• Female socket plug type with 270° wire entry orientation
• Free-hanging in-line mounting configuration
• Screw-based termination method
• 8A current rating (IEC and UL)
• 160V (IEC) and 300V (UL) voltage ratings
• Wire gauge support of 14-30 AWG minimum
• M2 screw size
• Black color and tin contact mating finish
• RoHS compliance and MSL 1 rating

The substitute part Phoenix Contact 1800252 meets all core compatibility criteria. It belongs to the COMBICON MCVW series and maintains identical electrical ratings, mechanical dimensions, and connector geometry. The primary technical distinction is the termination mechanism upgrade from standard screw to rising cage clamp screw, which provides enhanced wire retention characteristics while maintaining full backward compatibility with the original part's interface specifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1800252 is the qualified substitute for the obsolete 5452849 terminal block plug. Selection of the 1800252 is supported by the following engineering factors:

Product Status & Availability: The 1800252 maintains active product status with confirmed inventory availability (951 pcs), ensuring reliable procurement for both replacement and new design applications. The 5452849's obsolete classification necessitates transition to an actively supported alternative.

Regulatory Compliance: Both parts maintain identical RoHS compliance and MSL 1 ratings, ensuring compatibility with current environmental and moisture sensitivity requirements across manufacturing and field deployment environments.

Electrical & Mechanical Equivalence: The 1800252 preserves all critical electrical parameters (8A current, 160V/300V voltage ratings) and mechanical specifications (9-position, 3.81mm pitch, 270° wire entry, M2 screw, free-hanging mounting). The connector geometry and interface dimensions remain unchanged, enabling direct mechanical and electrical substitution.

Termination Enhancement: The upgrade from standard screw to rising cage clamp screw termination in the 1800252 provides improved wire retention and contact reliability without altering the connector's external form factor or mating interface. This represents a technical advancement rather than a compatibility limitation.

Wire Gauge Compatibility: The 1800252 supports the full 14-30 AWG range of the original part, with extended lower-gauge capability (0.14mm² versus 0.2mm²), ensuring compatibility with existing wire specifications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1800252 directly replace the 5452849 in existing installations?

A: Yes. The 1800252 maintains identical connector pitch (3.81mm), position count (9), wire entry angle (270°), mounting configuration (free-hanging in-line), and electrical ratings (8A, 160V IEC, 300V UL). The connector interfaces are mechanically and electrically compatible. The rising cage clamp termination represents an enhancement to wire retention without affecting mating compatibility.

Q: What is the difference between the screw termination in the 5452849 and the rising cage clamp screw in the 1800252?

A: Both employ M2 screw-based wire termination. The 1800252's rising cage clamp design provides enhanced wire grip and retention characteristics. The termination torque specification for the 1800252 is 0.22-0.25 Nm (1.9-2.2 Lb-In). This represents a functional improvement while maintaining full interface compatibility.

Q: Are there any wire gauge limitations when substituting the 1800252 for the 5452849?

A: No. The 1800252 supports 14-30 AWG (0.14-1.5mm²), which encompasses the full 14-30 AWG (0.2-1.5mm²) range of the original part. The 1800252 offers extended capability at smaller wire gauges.

Q: What is the packaging difference between these parts?

A: The 5452849 packaging is listed as unspecified. The 1800252 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5452849 and 1800252 are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity ratings, meeting current environmental and manufacturing standards.

Q: Why is the 5452849 classified as obsolete?

A: The 5452849 belongs to the BCVP series, which has been superseded by the COMBICON MCVW series represented by the 1800252. Phoenix Contact has transitioned product lines to the newer COMBICON MCVW platform, which incorporates enhanced termination technology and maintains active manufacturing and support status.
