Phoenix Contact 1702837 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1702837 is a 4-position terminal block header with female sockets designed for front panel wire connection and PCB-mounted rear panel pins at right angles. This component is part of the COMBICON DFK-IPC series and features threaded mating lock and shield connection on the front side. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1702837 is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the COMBICON DFK-IPC series
• Position Count: 4-position configuration required
• Pitch Specification: 0.400" (10.16mm) pitch maintained
• Electrical Ratings: Voltage (600 V UL) and current (5 A UL) ratings must be equal or exceed the original
• Panel Thickness Tolerance: 0.039 ~ 0.118" (1.0 ~ 3.0mm) compatibility
• Connection Type: Female socket front panel connection with right-angle PCB pins
• Color: Green housing
• Compliance: RoHS compliance required

The Phoenix Contact 1702510 qualifies as a substitute based on these parameters. The primary difference is the width dimension (2.550" vs. 3.217") and panel mount configuration variation, which represents a design optimization within the same series rather than a functional incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1702510 is the designated substitute for the obsolete 1702837. Both components maintain identical electrical specifications (600 V UL, 5 A UL), mechanical pitch (0.400"), position count (4), and panel thickness tolerance. Both are RoHS compliant with MSL rating of 1 (Unlimited).

The 1702510 offers the advantage of active product status, ensuring continued availability and manufacturing support. The width reduction from 3.217" to 2.550" reflects a design optimization within the COMBICON DFK-IPC series and does not affect electrical or functional compatibility when panel space permits the smaller footprint.

For applications where the original 3.217" width is a critical constraint, the 1702510 may require panel layout modification. In such cases, direct Phoenix Contact technical consultation is necessary to identify alternative solutions within the active product portfolio.

Frequently Asked Questions (FAQ)

Q: Can the 1702510 be used as a direct replacement for the 1702837?

A: Yes, from an electrical and functional standpoint. Both components share identical pitch (0.400"), position count (4), voltage rating (600 V UL), current rating (5 A UL), and panel thickness tolerance (0.039 ~ 0.118"). The primary consideration is the width difference: 2.550" versus 3.217". Panel layout compatibility must be verified before implementation.

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

A: The 1702837 has a width of 3.217" (81.72mm), while the 1702510 measures 2.550" (64.76mm). This 0.667" reduction represents a design optimization within the COMBICON DFK-IPC series. If your panel layout accommodates the narrower footprint, this difference is not a functional concern. If the original width is required, alternative solutions must be explored.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1702837 and 1702510 are RoHS compliant with an MSL rating of 1 (Unlimited moisture sensitivity level).

Q: Why is the 1702837 listed as obsolete?

A: The 1702837 has been discontinued by Phoenix Contact. The 1702510 represents the active product line continuation within the COMBICON DFK-IPC series and is the recommended substitute for new designs and ongoing maintenance applications.

Q: Are there any differences in panel mount configuration?

A: The 1702837 uses a 2-piece snap lock with front flange, while the 1702510 uses a 2-piece snap lock configuration. Both employ the same fundamental mounting principle and are compatible with the specified panel thickness range.

Q: What certifications apply to both parts?

A: Both components carry RoHS compliance certification and are rated for 600 V UL and 5 A UL electrical specifications. ECCN classification is EAR99 for both parts, and HTSUS code is 8536.69.4040.
