Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1702031 is determined by the following critical parameters:

• Mechanical Compatibility: Identical pitch (0.400"/10.16mm), width (2.992"/76.00mm), and panel thickness range (0.039 ~ 0.118") ensure physical interchangeability in existing panel cutouts and PCB layouts.
• Electrical Ratings: Voltage rating of 600V UL and current capacity must meet or exceed the original 5A specification.
• Configuration: 4-position header with male pins, right-angle PCB mounting, and 2-piece snap lock front flange design.
• Series Consistency: Parts within the COMBICON DFK-PC series maintain design compatibility.
• Environmental Compliance: RoHS compliance status ensures regulatory alignment for new applications.

The substitute part 1701553 meets all mechanical and electrical compatibility criteria while offering improved product status and enhanced current rating capacity.

Engineering Selection Recommendations

The Phoenix Contact 1701553 serves as a direct substitute for the obsolete 1702031 based on the following engineering criteria:

Product Status: The 1701553 maintains active product status, ensuring continued availability, technical support, and supply chain reliability. The 1702031 is classified as obsolete, limiting future procurement options.

Compliance and Certifications: Both parts maintain equivalent environmental compliance with RoHS standards. The 1701553 carries ROHS3 compliance, representing the current regulatory standard. Both parts are REACH unaffected and carry identical ECCN and HTSUS classifications.

Electrical Performance: The 1701553 provides enhanced current capacity at 66A compared to the original 5A rating, while maintaining the identical 600V UL voltage specification. This increased current rating provides additional design margin for applications operating at or near the original part's electrical limits.

Mechanical Interchangeability: Identical pitch, width, panel thickness range, and mounting configuration ensure direct physical replacement without panel modifications or PCB layout changes.

Frequently Asked Questions (FAQ)

Q: Can the 1701553 be used as a direct replacement for the 1702031 in existing designs?

A: Yes. The 1701553 is mechanically and electrically compatible with the 1702031. Identical pitch (0.400"), width (2.992"), panel thickness range (0.039 ~ 0.118"), and mounting configuration ensure direct substitution without design modifications.

Q: What is the difference in current rating between these parts?

A: The 1702031 is rated for 5A, while the 1701553 is rated for 66A at the same 600V UL voltage. Both parts meet the electrical requirements of applications designed for the original part.

Q: Are there packaging differences between the two parts?

A: The 1702031 packaging is listed as unspecified, while the 1701553 is supplied in bulk packaging. This difference does not affect functional compatibility or performance.

Q: Why should I transition from the 1702031 to the 1701553?

A: The 1702031 is obsolete, limiting future availability and support. The 1701553 is an active product with current ROHS3 compliance, ensuring long-term supply chain viability and regulatory alignment.

Q: Are the environmental specifications identical?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity rating and are REACH unaffected. The 1701553 carries current ROHS3 compliance compared to the RoHS compliance of the 1702031, representing updated regulatory standards.
