Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1701663 is determined by the following critical parameters:

• Positions Per Level: Must equal 7
• Pitch: Must equal 0.400" (10.16mm)
• Front Panel Connection Type: Must be Header, Male Pins
• Rear Panel Connection Type: Must be PCB Pins - Right Angle
• Panel Mount Type: Must be 2 Piece, Snap Lock
• Color: Must be Green
• Series Compatibility: COMBICON DFK-PC series

The substitute part 1701508 meets all these core mechanical and electrical interface requirements, ensuring direct functional equivalence for applications requiring identical form factor and connection topology.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1701508 is the direct substitute for the obsolete 1701663. Both components share identical mechanical interfaces, mounting configurations, and physical dimensions. The 1701508 maintains RoHS compliance and is currently in active production status, ensuring long-term availability and supply chain continuity.

The 1701508 exhibits different electrical ratings (300 V / 66 A versus 600 V / 5 A for the original part). Component selection must account for the specific voltage and current requirements of the target application. The substitute part supports higher current capacity while operating at reduced voltage specification.

Frequently Asked Questions (FAQ)

Q: Can the 1701508 be used as a direct replacement for the 1701663 in existing designs?

A: The 1701508 provides mechanical and form-factor equivalence. Electrical rating differences must be evaluated against application requirements. If the application operates within 300 V and 66 A specifications, direct substitution is valid.

Q: What are the key differences between these two parts?

A: The primary differences are product status (1701663 is obsolete; 1701508 is active) and electrical ratings. The 1701663 is rated 600 V / 5 A, while the 1701508 is rated 300 V / 66 A. All mechanical and interface parameters are identical.

Q: Are both parts available in the same packaging?

A: The 1701663 is supplied in standard packaging, while the 1701508 is supplied in bulk packaging. Both are RoHS compliant with MSL rating of 1 (Unlimited).

Q: Does the color specification affect substitution eligibility?

A: Yes. Both parts are green. Color consistency is maintained across the substitution, ensuring visual and functional compatibility in panel-mounted applications.

Q: What is the pitch specification, and why is it important for substitution?

A: Both parts feature 0.400" (10.16mm) pitch. This spacing is critical for PCB layout compatibility and connector mating. Pitch equivalence is a mandatory substitution criterion.
