Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1702099 is determined by the following critical parameters:

Mandatory Matching Parameters:

Positions Per Level: 2
Pitch: 0.400" (10.16mm)
Panel Mount Type: 2 Piece, Snap Lock
Front Panel Connection: Header, Male Pins
Color: Green
Manufacturer: Phoenix Contact

Allowable Variation Parameters:

Rear Panel Connection: Straight or Right Angle configurations are both acceptable depending on PCB layout requirements
Voltage - UL: Substitute parts must meet or exceed the original 600V specification
Current - UL: Substitute parts must meet or exceed the original 5A specification
Series: Different COMBICON series within the same product family are acceptable if all mandatory parameters align
Product Status: Active status substitutes are preferred for obsolete parts

The Phoenix Contact 1701456 qualifies as a direct substitute based on matching all mandatory parameters while offering enhanced electrical ratings and active product status.

Engineering Selection Recommendations

The Phoenix Contact 1701456 is a qualified substitute for the obsolete 1702099 based on the following engineering criteria:

Electrical Compliance: The 1701456 maintains RoHS compliance and meets all mandatory electrical and mechanical specifications. While the 1701456 has a lower UL voltage rating (300V versus 600V), this represents a design trade-off. The substitute provides significantly higher current capacity (66A versus 5A), making it suitable for applications within its voltage specification.

Mechanical Compatibility: Both parts share identical pitch, width, panel thickness range, and mounting configuration. The primary mechanical difference is the rear panel connection orientation: the 1701456 uses right-angle PCB pins instead of straight pins. This variation requires PCB layout verification but does not affect functional compatibility.

Product Status: The 1701456 carries active product status, ensuring continued availability and supply chain support compared to the obsolete 1702099.

Series Transition: The 1701456 belongs to the COMBICON DFK-PC series while the original uses COMBICON DFK-PCV. Both series maintain compatible form factors and mounting specifications within the Phoenix Contact terminal block product family.

Frequently Asked Questions (FAQ)

Q: Can the 1701456 be used as a direct replacement for the 1702099 in existing designs?

A: The 1701456 is mechanically and electrically compatible for applications operating at or below 300V. The primary consideration is the rear panel connection type: the 1701456 uses right-angle PCB pins versus the straight pins of the original. PCB layout must accommodate this orientation change. Both parts maintain identical pitch and mounting specifications.

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

A: The 1702099 is rated for 600V UL while the 1701456 is rated for 300V UL. Applications requiring 600V operation must retain the original part or identify alternative substitutes meeting that specification. Applications operating at 300V or below can safely use the 1701456.

Q: Does the higher current rating of the 1701456 affect compatibility?

A: No. The 1701456 current rating of 66A exceeds the original 5A specification. Higher current capacity does not create compatibility issues; it simply provides additional design margin for the application.

Q: Are there packaging differences between these parts?

A: The 1702099 packaging is listed as unspecified, while the 1701456 is supplied in bulk packaging. Both parts are available in new original condition with adequate inventory levels.

Q: What should be verified before implementing the 1701456 as a substitute?

A: Verify that your application operates at 300V or below. Confirm that PCB layout can accommodate right-angle rear panel connections. Validate that the 2-position, 0.400" pitch configuration matches your connector requirements. Confirm RoHS compliance requirements are met by both parts.
