Key Parameters

Substitute Part Grouping Explanation

Substitution for the Phoenix Contact 1686258 is based on the following critical parameters:

• Coaxial Type: Both the main part and substitute maintain coaxial signal transmission capability
• Gold Contact Finish: Electrical performance and environmental protection requirements are met through gold plating
• Solder Termination Compatibility: The substitute part features solder cup termination, which is compatible with solder-based assembly processes
• RoHS and MSL Compliance: Both parts meet RoHS requirements and carry MSL 1 rating, ensuring compatibility with modern manufacturing and storage conditions
• Phoenix Contact Manufacturer: Substitution remains within the same manufacturer ecosystem, ensuring design consistency and supply chain reliability

The substitute part 1655616 operates within the VS series and transitions from a pin configuration to a female socket configuration within the D-Sub connector category, maintaining the coaxial and solder termination characteristics necessary for functional equivalence in appropriate circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1655616 is classified as an active product, providing supply chain continuity for applications previously served by the obsolete 1686258. Both parts maintain identical RoHS3/RoHS compliance and MSL 1 ratings, ensuring compatibility with current manufacturing standards and storage protocols. The substitute part's active status provides long-term availability and support for production environments requiring reliable connector solutions.

Selection of the 1655616 as a substitute is appropriate for applications where coaxial signal integrity, gold contact finish, and solder termination methods are specified requirements. The transition from the HEAVYCON® M series to the VS series D-Sub connector platform represents a shift in mechanical form factor while preserving the critical electrical and environmental compliance characteristics.

Frequently Asked Questions (FAQ)
