Phoenix Contact 1702905 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1702905 is a 3-position terminal block header with female sockets designed for front panel wire connections and PCB-mounted rear connections. This component belongs to the COMBICON DFK-IPC series and features a green color designation with threaded mating lock and shield connection feedthrough capabilities.

The 1702905 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure procurement availability, and support ongoing system maintenance and repairs where original stock is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1702905 is determined by the following critical parameters:

• Electrical Specifications: Voltage rating (600 V UL) and current rating (5 A UL) must be maintained or exceeded
• Mechanical Configuration: 3 positions per level, 0.400" (10.16mm) pitch, female socket header design, and right-angle PCB pin orientation
• Interface Type: Front panel female socket connection with rear PCB-mounted right-angle pins
• Environmental Compliance: RoHS compliance and MSL rating of 1
• Series Compatibility: COMBICON DFK-IPC series designation

The substitute part 1702507 maintains all critical electrical and mechanical parameters while differing in physical width and panel mount flange configuration. Both components share identical pitch, position count, voltage/current ratings, and connector interface type.

Parameter Comparison

Engineering Selection Recommendations

The 1702507 serves as a direct functional substitute for the 1702905 based on electrical and mechanical parameter equivalence. Both components maintain identical voltage (600 V UL), current (5 A UL), position count (3), pitch (0.400"), and connector interface specifications.

The primary distinction is product status: the 1702905 is obsolete while the 1702507 is active. The 1702507 is RoHS compliant and carries an MSL rating of 1, meeting the same environmental and compliance requirements as the original part.

Physical width differs between the two components (2.817" versus 2.150"), and the panel mount flange configuration varies slightly. These dimensional differences must be evaluated against specific panel layout and mounting requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 1702507 replace the 1702905 in existing designs?

A: The 1702507 maintains electrical and mechanical compatibility in terms of pitch, position count, voltage rating, current rating, and connector interface type. Physical width and panel mount flange configuration differ and must be assessed against specific panel mounting constraints.

Q: Are there electrical performance differences between these parts?

A: No. Both components share identical UL voltage (600 V) and current (5 A) ratings, color designation (green), and connector interface specifications (female socket header with right-angle PCB pins).

Q: What is the significance of the product status difference?

A: The 1702905 is classified as obsolete, indicating discontinued manufacturing. The 1702507 is active and currently in production, ensuring ongoing availability for procurement and future orders.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1702905 and 1702507 are RoHS compliant with an MSL rating of 1 (unlimited moisture sensitivity level).

Q: What are the key dimensional differences?

A: The 1702905 has a width of 2.817" (71.56mm) with a front flange panel mount type, while the 1702507 has a width of 2.150" (54.60mm) with a standard snap lock panel mount type. Both accommodate panel thicknesses of 0.039 ~ 0.118" (1.0 ~ 3.0mm).

Q: Are these parts from the same manufacturer series?

A: Yes. Both components belong to the Phoenix Contact COMBICON DFK-IPC series, ensuring design consistency and interoperability within the same product family.
