Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5451242 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: 7-position plug with female sockets
• Pitch Specification: 0.200" (5.08mm) center-to-center spacing
• Orientation & Mounting: 90° wire entry, free-hanging in-line configuration
• Electrical Ratings: Minimum 12A (IEC) and 630V (IEC) capability
• Wire Compatibility: Support for 12-30 AWG (0.2-2.5mm²) conductors
• Termination Method: Screw-based connection mechanism
• Housing & Safety: Polyamide construction with UL94 V-0 flammability rating

The substitute part Phoenix Contact 1835148 meets all these criteria, maintaining full mechanical and electrical compatibility while offering enhanced termination technology (rising cage clamp) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1835148 is the direct functional equivalent for the obsolete 5451242 model. Both components share identical mechanical interfaces, electrical ratings (IEC standard), wire gauge compatibility, and safety certifications. The 1835148 offers the following advantages:

• Active Product Status: Currently manufactured and supported by Phoenix Contact, ensuring long-term availability and supply chain reliability
• Enhanced Termination Technology: Rising cage clamp mechanism provides improved contact reliability compared to standard screw termination
• Improved Compliance: ROHS3 certification provides broader regulatory coverage than RoHS Compliant designation
• Higher UL Current Rating: 15A (UL) versus 12A (UL) on the original part, offering additional design margin for North American applications
• Established Inventory: 895 units in stock versus 1139 units of the obsolete part

For new designs or system replacements, the 1835148 is the recommended selection. For legacy system maintenance requiring exact form-factor compatibility, the 5451242 remains functionally interchangeable where inventory permits.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1835148 directly replace the 5451242 in existing installations?

A: Yes. Both components maintain identical 7-position, 5.08mm pitch configuration, 90° wire entry orientation, and free-hanging in-line mounting. Electrical ratings (12A IEC, 630V IEC) and wire gauge compatibility (12-30 AWG) are equivalent. The M3 screw torque specification (0.5-0.6 Nm) remains unchanged.

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

A: The 5451242 uses standard screw termination. The 1835148 incorporates rising cage clamp technology, which provides enhanced contact pressure and improved connection reliability while maintaining the same M3 screw interface and torque specification.

Q: Are there packaging differences between these parts?

A: The 5451242 is supplied in standard packaging (not specified). The 1835148 is supplied in bulk packaging. Both are MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which part should be specified for new designs?

A: The Phoenix Contact 1835148 should be specified for new designs. It is an active product with current manufacturing support, improved termination technology, and higher UL current rating (15A versus 12A). The 5451242 is obsolete and should only be used for legacy system maintenance where exact part matching is required.

Q: Are the electrical ratings sufficient for my application?

A: Both parts are rated for 12A (IEC) and 630V (IEC), meeting standard industrial terminal block specifications. The 1835148 provides additional margin with 15A (UL) rating for North American applications. Verify your specific application requirements against these ratings before selection.

Q: What is the wire strip length requirement?

A: Both parts require 7mm wire strip length for proper termination. This specification must be observed during installation to ensure reliable screw contact and prevent insulation damage.
