Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1778001 qualifies as a direct substitute for the 1948734 based on the following critical parameters:

Matching Parameters:

• Identical number of positions (4)
• Identical pitch spacing (0.200" / 5.08mm)
• Identical plug type (Female Sockets)
• Identical wire entry orientation (180°)
• Identical termination method (Screw - Rising Cage Clamp)
• Identical mounting configuration (Free Hanging In-Line)
• Identical wire gauge compatibility (12-30 AWG / 0.2-2.5mm²)
• Identical screw size (M3)
• Identical material flammability rating (UL94 V-0)
• Same series family (COMBICON MSTB)

Functional Equivalence: The 1778001 maintains all mechanical and electrical interface characteristics required for direct replacement. Both components share identical connector geometry, contact arrangement, and termination methodology, ensuring compatibility in existing circuit designs and PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1778001 is the appropriate replacement for the obsolete 1948734 model. The substitute part maintains full mechanical and electrical compatibility while offering enhanced electrical ratings and active product status.

Compliance Considerations: Both components meet UL94 V-0 flammability requirements and carry RoHS compliance certifications. The 1778001 provides ROHS3 compliance status, representing current regulatory alignment. The 1778001 additionally carries REACH Unaffected status, providing extended environmental compliance documentation.

Electrical Performance: The 1778001 provides superior electrical ratings compared to the original part. IEC voltage rating increases from 250V to 630V, and UL current rating increases from 10A to 15A. These enhanced ratings ensure the substitute part operates safely across a broader range of application requirements without derating.

Availability and Support: The 1778001 maintains active product status with higher inventory availability (1403 units versus 846 units for the obsolete 1948734), ensuring reliable long-term procurement and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 1778001 directly replace the 1948734 in existing designs?

A: Yes. Both components share identical mechanical interfaces, connector geometry, pitch spacing, and termination methodology. No design modifications are required for direct substitution.

Q: What are the key differences between these parts?

A: The primary differences are product status and electrical ratings. The 1948734 is obsolete with 250V IEC rating and 10A UL current rating. The 1778001 is active with 630V IEC rating and 15A UL current rating. All mechanical and interface specifications remain identical.

Q: Are there packaging differences between the two parts?

A: Yes. The 1948734 is supplied with unspecified packaging, while the 1778001 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact component functionality or compatibility.

Q: Does the 1778001 require different installation procedures?

A: No. Both components use identical M3 screw termination with rising cage clamp design. Installation procedures, torque specifications, and wire gauge compatibility remain unchanged.

Q: What compliance certifications apply to the 1778001?

A: The 1778001 carries ROHS3 compliance, RoHS compliance, UL94 V-0 flammability rating, and REACH Unaffected status. These certifications exceed the compliance profile of the obsolete 1948734.

Q: Is the 1778001 suitable for higher voltage applications?

A: The 1778001 supports 630V IEC rating compared to the 1948734's 250V IEC rating. Applications requiring voltages between 250V and 630V benefit from the enhanced rating of the substitute part.
