C115288-6275 Equivalent & Substitute Parts

Part Overview

The C115288-6275 is a 21-position one-piece backshell connector from C&K's MDM series, designed for D-Sub applications with 180° cable exit and shielded configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. The backshell provides mechanical protection, shielding, and strain relief for D-Sub connector assemblies in aerospace and industrial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub backshell connectors is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the MDM series to ensure mechanical and electrical compatibility with existing D-Sub connector housings
• Position Count: The 21-position configuration is a fixed requirement for mating with 21-pin D-Sub connectors
• Cable Exit Angle: The 180° straight-back exit must be maintained for cable routing compatibility
• Shielding Configuration: Shielded design is required for EMI/RFI protection in the original application
• Material and Plating: Metal construction with gold plating ensures corrosion resistance and electrical performance consistency
• Accessory Classification: The part must function as a backshell component compatible with D-Sub connectors

The identified substitute C115288-6511 shares the MDM series designation and base product number (C115288), indicating design family compatibility. However, this part functions as a jackscrew/slotted fastener accessory rather than a one-piece backshell, representing a complementary component within the same connector assembly ecosystem.

Parameter Comparison

Engineering Selection Recommendations

The C115288-6275 is classified as obsolete, requiring alternative sourcing strategies. The C115288-6511 is an active product within the same MDM series family, sharing identical base product number, RoHS compliance level, MSL rating, and trade classification codes.

However, the C115288-6511 functions as a jackscrew/slotted fastener component rather than a one-piece backshell. Direct functional substitution is not applicable. The C115288-6511 serves as a complementary assembly component for D-Sub backshell configurations, not a replacement for the backshell itself.

For applications requiring the specific 21-position, 180° shielded backshell functionality of the C115288-6275, procurement should focus on identifying active MDM series backshell components with matching position count, cable exit angle, and shielding specifications. The active status of C115288-6511 indicates ongoing manufacturer support for the MDM connector family, suggesting availability of current-generation backshell alternatives within this series.

Frequently Asked Questions (FAQ)

Q: Can C115288-6511 directly replace C115288-6275 in existing assemblies?

A: No. The C115288-6511 is a jackscrew/slotted fastener accessory, not a backshell. These components serve different functions within D-Sub connector assemblies. Direct substitution is not possible.

Q: Why is C115288-6275 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. This necessitates identification of functionally equivalent alternatives or current-generation components within the same product family.

Q: What makes two backshell components interchangeable?

A: Interchangeability requires matching series designation (MDM), position count (21), cable exit angle (180°), shielding configuration (shielded), and material/plating specifications (metal with gold plating). All parameters must align for mechanical and electrical compatibility.

Q: Are there compliance differences between C115288-6275 and C115288-6511?

A: Both parts meet EAR99 export classification and share identical MSL ratings. The C115288-6511 carries ROHS3 compliance versus RoHS compliance for the main part, both acceptable for current applications. Both are subject to REACH regulations.

Q: What should be verified when sourcing a replacement for the C115288-6275?

A: Confirm the replacement component is an MDM series one-piece backshell with 21-position capacity, 180° cable exit, shielded design, and metal construction with gold plating. Verify active product status and current compliance certifications.
