Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C115288-6271 is determined by the following critical parameters: 31-position configuration, one-piece backshell design, 180° cable exit angle, shielded construction, round cable type, metal aluminum alloy material, and silver color finish. These parameters define the functional and mechanical compatibility requirements for direct substitution.

The substitute parts identified maintain these core specifications while differing in manufacturing status, plating composition, and packaging configuration. Substitution is valid when all critical parameters align with the original part specification.

Parameter Comparison

Engineering Selection Recommendations

C115288-6421 serves as the primary direct substitute for C115288-6271. Both components maintain identical 31-position, 180° shielded backshell specifications with matching material and color specifications. The primary distinction is plating composition: C115288-6271 uses nickel plating while C115288-6421 uses electroless nickel plating. Both meet RoHS compliance requirements, with C115288-6421 offering ROHS3 compliance and active product status, ensuring continued availability and supply chain stability.

C115288-6511 is a complementary accessory component classified as a jackscrew, slotted for D-Sub backshell use. This part is not a direct substitute for the backshell itself but functions as a related hardware component within the MDM series assembly.

Frequently Asked Questions (FAQ)

Q: Can C115288-6421 directly replace C115288-6271 in existing designs?

A: Yes. C115288-6421 maintains all critical functional parameters: 31-position configuration, one-piece backshell design, 180° cable exit, shielded construction, round cable type, metal aluminum alloy material, and silver finish. The electroless nickel plating in C115288-6421 provides equivalent corrosion resistance to the nickel plating in C115288-6271.

Q: What is the role of C115288-6511 in relation to C115288-6271?

A: C115288-6511 is a jackscrew component designed for use with D-Sub backshells in the MDM series. It is not a substitute for the backshell itself but rather a complementary hardware element that may be used in conjunction with backshell assemblies.

Q: Why is C115288-6271 classified as obsolete?

A: Product obsolescence indicates that the part is no longer in active production. C115288-6421 is the recommended active alternative, ensuring access to current manufacturing and supply chain support.

Q: Are there packaging differences between the main part and substitute?

A: C115288-6271 packaging information is not specified in available data. C115288-6421 is supplied in bulk packaging. Confirm packaging requirements with procurement specifications.

Q: Do the substitute parts meet the same compliance standards?

A: Both C115288-6271 and C115288-6421 are RoHS compliant. C115288-6421 additionally carries ROHS3 compliance and REACH affected status, meeting current regulatory requirements for aerospace and defense applications.
