Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1702141 has one identified equivalent: part number 1701508. Substitution eligibility is determined by the following critical parameters that must remain constant:

• Positions per level: 7 positions
• Pitch spacing: 0.400" (10.16mm)
• Front panel connection type: Header, Male Pins
• Panel mount configuration: 2 Piece, Snap Lock
• Panel thickness compatibility: 0.039 ~ 0.118" (1.0 ~ 3.0mm)
• Width: 4.665" (90.56mm)
• Color: Green
• Number of levels: 1

The substitute part 1701508 maintains all these critical parameters. However, the rear panel connection differs from straight to right-angle PCB pins, and electrical ratings vary. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 1701508 is the active equivalent for the obsolete 1702141. Both parts maintain identical mechanical and positional specifications, ensuring physical compatibility in panel-mount applications. The 1701508 offers the advantage of active product status with higher current capacity (66A versus 5A), supporting expanded application flexibility.

The primary consideration for substitution is the rear panel connection orientation: the 1701508 features right-angle PCB pins compared to the straight pins of the 1702141. This geometric difference requires verification against PCB layout constraints. The 1701508 operates at a lower UL voltage rating (300V versus 600V), which must be confirmed as acceptable for the intended circuit voltage.

Both parts maintain RoHS compliance and identical MSL ratings, supporting equivalent reliability and environmental performance in production environments.

Frequently Asked Questions (FAQ)

Q: Can the 1701508 directly replace the 1702141 in existing designs?

A: Physical mounting compatibility is maintained due to identical pitch, width, panel thickness range, and snap-lock configuration. However, the rear panel connection changes from straight to right-angle PCB pins. PCB layout verification is required to confirm the right-angle orientation accommodates existing trace routing and component placement.

Q: What are the electrical differences between these parts?

A: The 1702141 is rated for 600V UL and 5A current. The 1701508 is rated for 300V UL and 66A current. Applications operating above 300V UL require the original 1702141 specification or alternative parts meeting the higher voltage requirement. Applications requiring current capacity above 5A benefit from the 1701508's 66A rating.

Q: Why is the 1702141 obsolete?

A: The 1702141 belongs to the COMBICON DFK-PCV series, which has been superseded by the active DFK-PC series represented by the 1701508. Phoenix Contact has transitioned production to the newer series while maintaining mechanical and functional compatibility.

Q: Are there packaging differences between these parts?

A: The 1702141 packaging is listed as unspecified. The 1701508 is supplied in bulk packaging. Verify bulk packaging meets procurement and handling requirements for your application.

Q: Do both parts support the same panel thickness range?

A: Yes. Both the 1702141 and 1701508 accommodate panel thicknesses from 0.039" to 0.118" (1.0 to 3.0mm), ensuring compatibility across standard panel mounting applications.
