Phoenix Contact 1655700 D-Sub Backshell Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1655700 is a 25-position two-piece backshell connector with 45° cable exit and shielding, designed for D-Sub applications. This part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system maintenance and new design implementations. The connector features silver plating, ABS plastic construction, and IP20 protection rating, suitable for industrial D-Sub connector assemblies requiring shielded cable management.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1655700 is determined by the following critical parameters:

Number of Positions: Must be 25 to maintain connector compatibility
Compatible Shell Size: Must be B to ensure mechanical fit
Compatible D-Sub Size: Must support 25pos and HD44pos configurations
Shielding: Must be shielded to maintain electromagnetic protection
Material: ABS plastic construction for structural consistency
Cable Exit Angle: 45° cable exit is the primary distinguishing feature for direct equivalence
Plating Type: Metal plating required for electrical conductivity and corrosion resistance

Two substitute parts meet the specified criteria with varying degrees of parameter alignment. The first substitute differs in cable exit angle (180° vs. 45°), while the second substitute maintains identical cable exit geometry and shielding characteristics.

Engineering Selection Recommendations

ACOV-SUB-25MB2 (Assmann WSW Components) is the primary equivalent substitute for the Phoenix Contact 1655700. This part maintains identical mechanical and electrical parameters, including 45° cable exit angle, 25-position configuration, shell size B compatibility, and shielded construction. Both parts use ABS plastic with metal plating and support the same D-Sub sizes. The ACOV-SUB-25MB2 is currently in active production status with ROHS3 compliance, providing long-term availability and regulatory alignment. Nickel over copper plating offers enhanced corrosion resistance compared to generic metal plating.

1419719 (Phoenix Contact) is an alternative substitute from the same manufacturer, maintaining the same connector family and construction standards. However, this part features a 180° cable exit angle instead of 45°, which represents a significant geometric difference. This substitute is suitable only when cable routing requirements permit straight-back cable exit configurations. The 1419719 is active production status with RoHS compliance and includes assembly hardware and strain relief features.

Selection between these substitutes depends on cable routing geometry requirements. For applications requiring 45° cable exit, ACOV-SUB-25MB2 is the direct equivalent. For applications where 180° cable exit is acceptable or preferred, 1419719 provides an alternative from the original manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the ACOV-SUB-25MB2 be used as a direct replacement for the Phoenix Contact 1655700?

A: Yes. Both parts share identical specifications for number of positions (25), shell size (B), D-Sub compatibility (25pos and HD44pos), cable exit angle (45°), shielding (shielded), material (ABS), and color (silver). The ACOV-SUB-25MB2 is manufactured by Assmann WSW Components and is currently in active production.

Q: What is the primary difference between the 1419719 and the 1655700?

A: The cable exit angle differs. The 1655700 features 45° cable exit, while the 1419719 features 180° cable exit. All other mechanical and electrical parameters remain identical. This difference affects cable routing geometry in the assembly.

Q: Are both substitute parts RoHS compliant?

A: Yes. The 1419719 is RoHS Compliant, and the ACOV-SUB-25MB2 is ROHS3 Compliant. Both meet current regulatory requirements for restricted substances.

Q: What is the difference in plating between the main part and the ACOV-SUB-25MB2?

A: The Phoenix Contact 1655700 specifies generic metal plating, while the ACOV-SUB-25MB2 specifies nickel over copper plating. Nickel over copper provides enhanced corrosion resistance and improved electrical conductivity in high-reliability applications.

Q: Can I use the 1419719 if my application requires 45° cable exit?

A: No. The 1419719 features 180° cable exit and is not suitable for applications requiring 45° cable routing. Use the ACOV-SUB-25MB2 for 45° cable exit requirements.

Q: Are these parts available in different packaging options?

A: The 1419719 and ACOV-SUB-25MB2 are both supplied in bulk packaging. The original 1655700 packaging specification was not provided in the technical data.

Q: What is the inventory status of these substitute parts?

A: The ACOV-SUB-25MB2 has 786 pieces in stock, and the 1419719 has 1051 pieces in stock. Both are available as new original components.
