Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1766938 is determined by the following critical parameters that must remain constant:

• Connector Type: Plug with female sockets
• Position Count: 10 positions
• Pitch Specification: 0.150" (3.81mm)
• Series Compatibility: COMBICON MC
• Mounting Configuration: Free hanging (in-line)
• Electrical Classification: Terminal block plug category

The substitute part 1827787 maintains all these core parameters while offering enhanced specifications in wire entry configuration, termination method, and electrical ratings. Both parts share identical position count, pitch, mounting type, and series designation, establishing direct substitution compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1827787 serves as the direct substitute for the obsolete 1766938 based on matching core mechanical and electrical interface parameters. The substitute part maintains identical position count, pitch, mounting configuration, and series designation while offering active product status and enhanced compliance certification (ROHS3 vs. RoHS Compliant).

The 1827787 provides defined electrical ratings (8A IEC/UL, 320V IEC, 300V UL) and specified wire gauge compatibility (14-30 AWG, 0.14-1.5mm²), enabling precise system integration. The screw-type termination with rising cage clamp and 180° wire entry configuration represents the current production standard for this connector family.

Both parts maintain MSL 1 rating and are classified under identical ECCN and HTSUS codes, confirming regulatory equivalence. Selection of the 1827787 is appropriate for new designs and replacement applications requiring the 10-position, 3.81mm pitch COMBICON MC plug configuration.

Frequently Asked Questions (FAQ)

Q: Can the 1827787 directly replace the 1766938 in existing installations?

A: Yes. Both parts share identical position count (10), pitch (0.150"/3.81mm), mounting type (free hanging in-line), and series designation (COMBICON MC). The mechanical interface is fully compatible. The 1827787 provides enhanced specifications including defined electrical ratings and active product status.

Q: What is the significance of the 180° plug wire entry on the 1827787?

A: The 180° wire entry specification on the 1827787 defines the orientation at which wires enter the connector housing. This parameter was not specified on the obsolete 1766938. Verify that the 180° entry angle accommodates your cable routing requirements in the target application.

Q: Are there compliance differences between the two parts?

A: The 1766938 carries RoHS Compliant certification, while the 1827787 carries ROHS3 Compliant certification, representing an updated compliance standard. Both parts maintain MSL 1 (Unlimited) rating and identical ECCN/HTSUS classifications.

Q: What wire gauges are supported by the 1827787?

A: The 1827787 accepts wire gauges from 14-30 AWG (0.14-1.5mm²). Confirm that your existing wire specifications fall within this range before implementation.

Q: Does the screw termination method on the 1827787 differ from the 1766938?

A: The 1827787 specifies screw-type termination with rising cage clamp design. The 1766938 termination style was not specified in available documentation. The rising cage clamp design on the 1827787 represents current Phoenix Contact production standards for this connector series.

Q: What is the recommended screw torque for the 1827787?

A: The specified torque range is 0.22-0.25 Nm (1.9-2.2 Lb-In) using M2 screws. Adhere to this torque specification to ensure proper contact pressure and electrical performance.
