Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the Phoenix Contact 1702109 is based on the following critical parameters that determine functional equivalence:

Mandatory Matching Parameters:

• Positions per level: 3
• Pitch: 0.400" (10.16mm)
• Width: 1.965" (49.92mm)
• Panel thickness range: 0.039 ~ 0.118" (1.0 ~ 3.0mm)
• Front panel connection type: Header, Male Pins
• Panel mount type: 2 Piece, Snap Lock
• Number of levels: 1
• Color: Green
• RoHS Compliance: Required

Variable Parameters Allowing Substitution:

• Rear panel connection orientation (straight vs. right angle)
• Voltage rating (minimum 300V UL acceptable for lower-voltage applications)
• Current rating (higher ratings provide design margin)
• Series designation (different COMBICON series within Phoenix Contact portfolio)
• Product status (active status preferred for new procurement)

The Phoenix Contact 1702109 has one identified substitute: part number 1701469, which maintains all mandatory matching parameters while offering an active product status and enhanced electrical ratings.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): Phoenix Contact 1701469 serves as the primary substitute for the obsolete 1702109. Both components maintain identical mechanical dimensions, pitch spacing, and mounting configuration. The 1701469 offers active product status, ensuring long-term availability and supply chain continuity. The primary design difference is the rear panel connection orientation (right angle vs. straight), which requires PCB layout evaluation for compatibility.

Electrical Considerations: The 1701469 operates at 300V UL versus the 1702109's 600V rating. Applications requiring the full 600V capability must evaluate whether the 300V substitute meets system voltage requirements. The 1701469 provides significantly higher current capacity (66A vs. 5A), offering enhanced performance margin for current-carrying applications.

Compliance Status: Both components maintain RoHS compliance and identical moisture sensitivity levels (MSL 1 - Unlimited), ensuring regulatory and environmental compatibility across industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1701469 directly replace the 1702109 in existing designs? A: Mechanical and electrical compatibility exists for applications operating at 300V or below. The primary design consideration is the rear panel connection orientation: the 1701469 uses right-angle PCB pins versus the 1702109's straight configuration. PCB layout must accommodate this difference.

Q: What is the voltage difference between these parts, and does it affect substitution? A: The 1702109 is rated 600V UL while the 1701469 is rated 300V UL. For applications operating below 300V, the 1701469 is suitable. Systems requiring 600V operation must retain the original specification or identify alternative components rated for that voltage.

Q: Are both parts RoHS compliant? A: Yes, both the 1702109 and 1701469 are RoHS compliant with identical moisture sensitivity levels (MSL 1 - Unlimited), meeting environmental and regulatory requirements for industrial applications.

Q: Why is the 1702109 obsolete, and what does this mean for procurement? A: Obsolete status indicates the 1702109 is no longer manufactured by Phoenix Contact. The 1701469 is the active equivalent, ensuring availability for new designs and ongoing system support. Existing inventory of the 1702109 remains available but should be transitioned to the active substitute for long-term supply security.

Q: How do the current ratings differ, and what is the practical impact? A: The 1702109 carries 5A capacity while the 1701469 carries 66A. For applications requiring only 5A or less, both are suitable. The 1701469's higher rating provides additional design margin and supports higher-current applications without component substitution.

Q: Are the pitch and position configurations identical? A: Yes, both components feature 3 positions at 0.400" (10.16mm) pitch with identical width (1.965" / 49.92mm) and panel thickness range (0.039 ~ 0.118" / 1.0 ~ 3.0mm). Mechanical compatibility is maintained across all standard mounting configurations.
