Phoenix Contact 1716878 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1716878 is a 2-position terminal block header from the COMBICON DFK-MSTB series, featuring male pins with black housing. This component serves as the front panel interface for quick-connect terminal block systems, designed for screw-mount applications with front flange installation. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and functional characteristics align within acceptable tolerances for the terminal block category.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for terminal block headers is based on the following critical parameters that must remain constant or within acceptable tolerances:

• Electrical Ratings: Voltage (300 V UL) and current (15 A UL) capacity must be identical
• Position Count: 2-position configuration required
• Pitch Tolerance: Nominal 0.200" (5.08mm) with minor manufacturing variation acceptable
• Connector Type: Header with male pins and quick-connect rear interface
• Mount Configuration: Screw mount with front flange for panel installation
• Panel Thickness Compatibility: 0.020 ~ 0.157" (0.5 ~ 4.0mm) range
• Compliance: RoHS3 compliance and REACH unaffected status maintained

The substitute part Phoenix Contact 0707109 meets these criteria with minor dimensional variation in width and pitch within manufacturing tolerances for the COMBICON DFK-MSTB series.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1716878 and 0707109 are active production components with identical electrical ratings, mechanical mounting configurations, and regulatory compliance. Selection between these parts should be based on the following factors:

1716878 (Black Housing): Primary selection when black color coding is required for circuit identification or panel aesthetics. Maintains standard inventory availability of 823 units.

0707109 (Green Housing): Alternative selection when green color coding is specified or preferred. Higher inventory availability of 1,232 units supports extended lead time requirements.

Both parts maintain ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating. Dimensional variations in pitch (0.197" vs 0.200") and width (1.181" vs 1.200") fall within acceptable manufacturing tolerances for the COMBICON DFK-MSTB series and do not affect functional compatibility in standard panel mount applications.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 0707109 be used as a direct replacement for 1716878?

A: Yes. Both parts share identical electrical ratings (300 V, 15 A), position count (2), pitch tolerance, mounting configuration, and compliance certifications. The primary difference is housing color (green vs. black). Dimensional variations are within manufacturing tolerances for the series.

Q: What is the pitch tolerance between these parts?

A: The main part specifies 0.200" (5.08mm) pitch, while the substitute specifies 0.197" (5.00mm). This 0.003" (0.08mm) difference is within acceptable manufacturing tolerance for COMBICON DFK-MSTB series terminal blocks and does not affect connector alignment or functionality.

Q: Are both parts RoHS3 compliant?

A: Yes. Both 1716878 and 0707109 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does housing color affect electrical performance?

A: No. Housing color is a visual identification feature only and does not impact electrical characteristics, current capacity, voltage rating, or mechanical function. Selection should be based on circuit identification requirements or panel design specifications.

Q: What panel thickness range do these headers support?

A: Both parts support panel thickness from 0.020" to 0.157" (0.5 to 4.0mm), accommodating standard PCB and panel mount applications within this range.

Q: Are the quick-connect rear interfaces identical?

A: Yes. Both parts feature identical quick-connect rear interfaces with 0.110" (2.80mm) solder eyelet configuration, ensuring compatibility with standard COMBICON DFK-MSTB series receptacles.
