Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1703276 is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the COMBICON DFK-IPCV series
• Position Count: 8 positions per level (fixed requirement)
• Pitch Specification: 0.400" (10.16mm) center-to-center spacing
• Electrical Ratings: 600 V UL voltage and 5 A UL current ratings
• Connection Type: Female sockets for front panel, PCB pins straight for rear
• Panel Thickness Tolerance: 0.039 ~ 0.118" (1.0 ~ 3.0mm)
• Color: Green housing
• Compliance: RoHS compliant status

The Phoenix Contact 1703111 qualifies as a substitute based on matching all critical electrical, mechanical, and dimensional parameters within the COMBICON DFK-IPCV series.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1703111 serves as the active substitute for the obsolete 1703276 model. Both components maintain identical electrical ratings (600 V UL, 5 A UL), mechanical pitch (0.400"), position count (8), and panel thickness tolerance specifications. Both are RoHS compliant and belong to the same COMBICON DFK-IPCV series.

The primary distinction is product status: the 1703276 is obsolete while the 1703111 is active and currently in production. The 1703111 features a reduced width of 4.150" (105.40mm) compared to the 1703276 at 4.817" (122.36mm), which may require panel layout verification during integration.

For new designs and ongoing system support where the 1703276 is no longer available, the 1703111 is the designated equivalent component within the Phoenix Contact product line.

Frequently Asked Questions (FAQ)

Q: Can the 1703111 directly replace the 1703276 in existing applications?

A: The 1703111 matches all critical electrical and mechanical parameters (voltage, current, pitch, position count, panel thickness tolerance, and connection types). The width difference (4.817" vs. 4.150") must be evaluated against panel mounting constraints in your specific application.

Q: Are both parts RoHS compliant?

A: Yes, both the 1703276 and 1703111 are RoHS compliant with MSL rating of 1 (Unlimited).

Q: Why is the 1703276 listed as obsolete?

A: The 1703276 has been discontinued by Phoenix Contact. The 1703111 is the active production equivalent within the COMBICON DFK-IPCV series.

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

A: The 1703276 measures 4.817" (122.36mm) in width while the 1703111 measures 4.150" (105.40mm). This dimensional difference affects panel mounting footprint and must be considered during mechanical design integration.

Q: Are the electrical ratings identical between both parts?

A: Yes, both components are rated for 600 V UL voltage and 5 A UL current, with identical pitch spacing of 0.400" (10.16mm) and 8-position configuration.

Q: What packaging is available for the 1703111?

A: The 1703111 is supplied in bulk packaging.
