Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1703289 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Voltage rating (600V UL) and current capacity (5A) must remain constant
• Mechanical Configuration: 9 positions per level with 0.400" (10.16mm) pitch spacing
• Connection Type: Female socket header on front panel with straight PCB pins on rear
• Panel Mount Compatibility: Panel thickness tolerance of 0.039 ~ 0.118" (1.0 ~ 3.0mm)
• Series Compatibility: COMBICON DFK-IPCV series designation
• Environmental Compliance: RoHS compliance and MSL rating

The substitute part Phoenix Contact 1703124 maintains equivalence across all critical electrical and mechanical parameters while differing in product status (active versus obsolete) and physical width dimensions.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1703124 serves as a direct electrical and functional equivalent to the obsolete 1703289. Both components maintain identical voltage and current ratings, position configuration, pitch spacing, and connection topology. The primary distinction is product lifecycle status: 1703124 is actively manufactured and stocked, while 1703289 is obsolete.

The width dimension difference (5.217" versus 4.550") reflects design refinement within the COMBICON DFK-IPCV series. This dimensional variance requires mechanical layout verification during component substitution to ensure panel cutout and mounting compatibility with existing installations.

Both parts maintain RoHS compliance and unlimited moisture sensitivity rating, supporting deployment in standard industrial environments without additional environmental protection measures.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1703124 replace 1703289 in existing installations?

A: Electrical and functional compatibility is confirmed across all rated parameters. Mechanical compatibility depends on panel cutout dimensions and mounting hole spacing, which must be verified against the specific installation geometry.

Q: What is the significance of the width dimension difference?

A: The 1703124 features a reduced width of 4.550" compared to the 1703289 at 5.217". This affects panel mounting footprint and requires confirmation that the panel opening accommodates the substitute part.

Q: Are there any compliance or certification differences?

A: Both parts maintain identical RoHS compliance status and MSL rating. No additional certifications or compliance measures are required when substituting between these parts.

Q: Why is 1703289 listed as obsolete?

A: Product status reflects Phoenix Contact's manufacturing lifecycle. The 1703124 represents the current active equivalent within the COMBICON DFK-IPCV series.

Q: What parameters must remain constant for substitution?

A: Voltage rating (600V), current capacity (5A), position count (9), pitch spacing (0.400"), connection type (female socket header with straight PCB pins), and panel thickness tolerance (0.039 ~ 0.118") must all remain unchanged for functional equivalence.
