C115288-6277 Equivalent & Substitute Parts

Part Overview

The C115288-6277 is a 31-position one-piece backshell connector with 180° cable exit and shielding, manufactured by C&K in the MDM series. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. The backshell assembly provides mechanical protection, shielding integrity, and standardized mating interfaces for D-Sub connector systems requiring gold-plated contacts and metal construction.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C115288-6277 is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the MDM series to ensure mechanical and electrical interface alignment
• Position Count: 31-position configuration is mandatory for connector shell compatibility
• Accessory Classification: The substitute must function within the D-Sub backshell assembly ecosystem
• Shielding Requirement: Shielded construction is required to maintain electromagnetic integrity
• Material and Plating: Metal construction with gold plating ensures corrosion resistance and contact reliability
• Environmental Compliance: RoHS and MSL ratings must meet or exceed the original specification

The C115288-6511 qualifies as a substitute component within the MDM series ecosystem. However, this part functions as a jackscrew assembly rather than a complete backshell, indicating it serves a complementary role in the overall connector system rather than a direct one-to-one replacement.

Engineering Selection Recommendations

For Direct Backshell Replacement: The C115288-6277 is classified as obsolete. Procurement should prioritize active-status alternatives within the MDM series that maintain 31-position, 180° shielded backshell configuration with metal aluminum alloy construction and gold plating.

For System Integration: The C115288-6511 is an active-status component within the same MDM series and shares identical environmental compliance ratings (MSL 1, ROHS3 Compliant, EAR99 classification). However, this part is a jackscrew assembly designed for use with D-Sub backshells rather than a complete backshell unit. Integration requires confirmation that the system architecture accommodates jackscrew-based fastening mechanisms.

Compliance Continuity: Both components maintain equivalent export control classification (EAR99) and tariff coding (8538.90.8180), supporting regulatory consistency in procurement workflows.

Frequently Asked Questions (FAQ)

Q: Can C115288-6511 directly replace C115288-6277 in existing assemblies?

A: No. The C115288-6511 is a jackscrew component, not a complete backshell. Direct substitution is not possible without system redesign. The C115288-6511 functions as a fastening element within backshell assemblies rather than as a backshell unit itself.

Q: What makes these parts substitutable within the MDM series?

A: Both components share MDM series designation, identical MSL ratings, matching RoHS compliance levels, and equivalent export control classifications. Series membership ensures mechanical interface compatibility for D-Sub connector systems.

Q: Are there environmental or compliance concerns with using the C115288-6511 as a system component?

A: No. The C115288-6511 maintains ROHS3 compliance, which exceeds the RoHS Compliant status of the original part. MSL 1 rating indicates unlimited moisture sensitivity protection. Both components carry identical ECCN and HTSUS classifications.

Q: Why is the C115288-6277 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Active-status alternatives should be evaluated for new designs or long-term procurement planning. The C115288-6511 represents an active-status component within the same product family.

Q: What parameters must remain constant when selecting MDM series backshell alternatives?

A: Position count (31), cable exit angle (180°), shielding requirement, metal aluminum alloy construction, and gold plating must be maintained. Series designation (MDM) ensures mechanical compatibility with existing connector interfaces.
