Phoenix Contact 1702950 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1702950 is an 8-position terminal block header with female sockets designed for front panel wire connections and PCB pin rear connections. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The COMBICON DFK-IPC series provides standardized terminal block solutions for industrial control and signal distribution applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1702950 is determined by the following critical parameters:

• Electrical Specifications: Voltage rating (600 V UL) and current rating (5 A UL) must remain constant
• Mechanical Configuration: 8 positions per level with 0.400" (10.16mm) pitch spacing
• Connection Type: Female socket front panel connection with right-angle PCB pin rear connection
• Environmental Compliance: RoHS compliance and MSL rating (1 - Unlimited)
• Series Compatibility: COMBICON DFK-IPC series maintains standardized form factors and mounting interfaces

The Phoenix Contact 1702950 is obsolete; however, the 1702552 maintains identical electrical ratings, position count, pitch spacing, and series designation while offering active product status. Dimensional variations exist in overall width, reflecting design refinements within the same series.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1702552 serves as the direct substitute for the obsolete 1702950 within the COMBICON DFK-IPC series. Both components maintain identical electrical specifications (600 V, 5 A), mechanical pitch (0.400"), position count (8), and environmental compliance ratings (RoHS, MSL 1).

The 1702552 is the recommended selection for new designs and replacement applications due to its active product status and continued availability. The dimensional difference in width (4.150" versus 4.817") reflects design optimization within the series and does not affect electrical or functional compatibility when panel thickness and mounting requirements are within the specified range of 0.039 ~ 0.118" (1.0 ~ 3.0mm).

Both components carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 1702552 directly replace the 1702950 in existing installations?

A: Yes. Both components share identical electrical ratings (600 V, 5 A), position configuration (8 positions), pitch spacing (0.400"), connection types (female socket front, right-angle PCB pin rear), and panel thickness compatibility (0.039 ~ 0.118"). The width difference does not affect functional compatibility when panel mounting dimensions are verified.

Q: What is the significance of the width difference between these parts?

A: The 1702950 measures 4.817" (122.36mm) in width, while the 1702552 measures 4.150" (105.40mm). This dimensional variation reflects design refinement within the COMBICON DFK-IPC series. Panel mounting compatibility depends on available panel space and the snap-lock mounting mechanism, not on the electrical or signal distribution characteristics.

Q: Are there packaging differences between these substitutes?

A: The 1702950 packaging is listed as unspecified, while the 1702552 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact component performance or electrical characteristics.

Q: Why is the 1702950 classified as obsolete?

A: Product obsolescence reflects manufacturer discontinuation decisions. The 1702552 represents the active continuation within the same series, maintaining all critical electrical and mechanical specifications required for system compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1702950 and 1702552 are RoHS compliant with MSL rating 1 (Unlimited moisture sensitivity), and both carry identical ECCN and HTSUS classifications, confirming regulatory and trade compliance equivalence.
