Phoenix Contact 1702125 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1702125 is a 5-position terminal block header with male pins and straight PCB connection, designed for panel-mount applications with snap-lock installation. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and new design implementations. The part operates at 600V UL voltage rating with 5A current capacity and is housed in a green connector body with 0.400" pitch spacing.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1701485 qualifies as a substitute for the 1702125 based on the following matching parameters:

• Identical 5-position configuration with 0.400" (10.16mm) pitch spacing
• Matching physical width of 2.765" (70.24mm)
• Compatible panel thickness range of 0.039 ~ 0.118" (1.0 ~ 3.0mm)
• Same snap-lock panel mount mechanism
• Identical green color specification
• Same RoHS compliance and MSL rating

The primary distinction between these parts lies in the rear panel wire connection type: the 1702125 features straight PCB pins, while the 1701485 provides right-angle PCB pins. This geometric difference affects board layout integration but does not impact electrical compatibility for applications where the connector orientation can be accommodated.

Parameter Comparison

Engineering Selection Recommendations

The 1701485 is an active production part from Phoenix Contact, providing continuity for applications currently using the obsolete 1702125. Both components maintain RoHS compliance and identical MSL ratings, ensuring environmental and reliability standards are preserved.

Selection between these parts depends on PCB layout requirements. The 1702125's straight pin configuration suits applications where vertical board mounting is required, while the 1701485's right-angle pins accommodate horizontal or edge-mounted PCB installations. The 1701485 offers higher current capacity (66A versus 5A) and lower voltage rating (300V versus 600V), making it suitable for higher-current, lower-voltage applications.

For direct replacement in existing designs, the 1701485 requires PCB layout modification to accommodate the right-angle pin geometry. Electrical specifications must be verified against application requirements, particularly voltage and current ratings.

Frequently Asked Questions (FAQ)

Q: Can the 1701485 directly replace the 1702125 without PCB modification?

A: Physical substitution is possible due to matching pitch, width, and panel thickness specifications. However, the rear panel connection geometry differs: the 1702125 uses straight pins while the 1701485 uses right-angle pins. PCB layout modification is required if the original design accommodates only straight pin orientation.

Q: What are the key differences in electrical ratings?

A: The 1702125 is rated for 600V at 5A, while the 1701485 is rated for 300V at 66A. Applications must operate within the selected part's voltage and current specifications. The 1701485 supports higher current but lower voltage operation.

Q: Why is the 1702125 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 1701485 serves as the active equivalent, providing continued availability and support for this connector family.

Q: Are both parts RoHS compliant?

A: Yes, both the 1702125 and 1701485 are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level), meeting environmental and reliability standards.

Q: What is the significance of the series designation change from DFK-PCV to DFK-PC?

A: The series designation reflects the product line evolution within Phoenix Contact's COMBICON family. The DFK-PC series represents the current active production line, while DFK-PCV is the obsolete predecessor. Both maintain mechanical and electrical compatibility within the specified parameters.
