Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1701840 is determined by strict alignment with the following core parameters:

Critical Matching Parameters:

• Number of positions: 5
• Pitch: 0.200" (5.08mm)
• Type: Plug with female sockets
• Plug wire entry orientation: 180°
• Termination style: Screw-rising cage clamp
• Mounting type: Free hanging (in-line)
• Wire gauge compatibility: 12-30 AWG (0.2-2.5mm²)
• Insulation height: 0.591" (15.00mm)
• Series: COMBICON MSTB

Acceptable Parameter Variations: Substitute parts may exceed the original electrical ratings (current and voltage) while maintaining all mechanical and dimensional specifications. Enhanced compliance certifications and improved product status (active vs. obsolete) are acceptable improvements.

The Phoenix Contact 1701840 has one identified substitute within the COMBICON MSTB series that maintains full mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1876628 is the direct active equivalent for the obsolete 1701840 model. Both components share identical mechanical dimensions, pitch, connector type, and wire gauge specifications, ensuring direct form-fit-function compatibility.

The 1876628 provides enhanced electrical performance with increased IEC voltage rating (630V vs. 320V) and UL current rating (15A vs. 10A), while maintaining the same IEC current rating and UL voltage rating as the original part. The substitute includes additional engineering documentation through specified screw size (M3) and torque parameters (0.5-0.6 Nm), along with material flammability certification (UL94 V-0) and regulatory compliance status (ROHS3, REACH Unaffected).

For applications requiring the 1701840, the 1876628 is the recommended replacement, offering improved specifications and active product status with full manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1876628 directly replace the 1701840 in existing installations?

A: Yes. Both parts maintain identical mechanical specifications including 5-position configuration, 0.200" (5.08mm) pitch, 180° wire entry, free-hanging mounting, and wire gauge compatibility (12-30 AWG). The connector footprint and mating interface are identical.

Q: What are the electrical differences between these parts?

A: The 1876628 exceeds the original ratings in two parameters: IEC voltage rating increases from 320V to 630V, and UL current rating increases from 10A to 15A. The IEC current rating (12A) and UL voltage rating (300V) remain unchanged. For applications operating within the original 1701840 specifications, the 1876628 is fully compatible.

Q: Why is the 1701840 listed as obsolete?

A: The 1701840 has been superseded by the 1876628 within the COMBICON MSTB series. The 1876628 provides equivalent functionality with enhanced electrical performance and improved regulatory compliance documentation.

Q: Are there packaging differences between these parts?

A: The 1701840 packaging specification is not provided. The 1876628 is supplied in bulk packaging. Consult with Phoenix Contact for specific packaging requirements or custom configurations.

Q: What compliance certifications apply to the 1876628?

A: The 1876628 is ROHS3 compliant, REACH unaffected, and carries UL94 V-0 material flammability rating. The original 1701840 compliance specifications are not fully documented.

Q: Are there any application limitations when substituting the 1876628 for the 1701840?

A: No. The 1876628 meets or exceeds all specified parameters of the 1701840. Applications designed for the original part will operate within the electrical and mechanical capabilities of the substitute.
