Substitute Part Grouping Explanation

Substitution of the obsolete 554726-1 with active equivalent components is based on strict alignment of the following critical parameters:

• Series Compatibility: Both parts belong to the CHAMP series for D-Sub shielded cable connectors
• Accessory Type: Identical jackscrew, slotted design
• Thread Specification: Matching 4-40 thread size
• Mechanical Dimensions: Identical length below head at 0.265" (6.73mm)
• Application: Both designated for CHAMP D-Sub shielded cable connector systems
• Manufacturer: Single-source supply from TE Connectivity AMP Connectors

The substitute part 5554726-1 maintains full mechanical and functional equivalence to the main part while offering active product status and current compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5554726-1 is the direct equivalent for the obsolete 554726-1. Selection of the substitute is based on the following engineering criteria:

Product Status: The main part 554726-1 carries obsolete status, limiting future availability and support. The substitute 5554726-1 maintains active product status, ensuring continued procurement capability and manufacturer support.

Compliance Certifications: The substitute 5554726-1 is ROHS3 compliant and REACH unaffected, providing regulatory alignment for applications subject to environmental and chemical restriction directives. The main part carries undefined compliance status.

Mechanical Equivalence: All critical mechanical parameters—thread size (4-40), length below head (0.265"/6.73mm), and series designation (CHAMP)—are identical between the main and substitute parts, ensuring direct functional interchangeability in CHAMP D-Sub shielded cable connector assemblies.

Inventory Availability: The substitute part maintains active inventory status with 782 pieces in stock, supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can 5554726-1 be used as a direct replacement for 554726-1 in existing CHAMP D-Sub connector assemblies?

A: Yes. The substitute part 5554726-1 maintains identical mechanical specifications, thread size (4-40), and length dimensions (0.265"/6.73mm). Both parts are designed for CHAMP D-Sub shielded cable connectors and are functionally equivalent.

Q: What is the primary reason for substituting 554726-1?
