DEFME-101 D-Sub Backshell Connector Equivalent & Substitute Parts

Part Overview

The DEFME-101 is a 9-position two-piece backshell connector manufactured by ITT Cannon, LLC, designed for D-Sub applications with 180° cable exit orientation and shielded construction. This component is classified as an active product with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary functional requirements remain constant.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DEFME-101 is determined by strict alignment of the following critical parameters:

• Number of Positions: Must be 9
• Compatible Shell Size: Must be E
• Compatible D-Sub Size: Must support 9pos and HD15pos
• Accessory Type: Must be Two Piece Backshell
• Shielding: Must be Shielded
• Cable Type: Must be Round
• Hardware: Must include Assembly Hardware, Strain Relief, and Mating Screws 4-40
• Product Status: Must be Active
• RoHS Compliance: Must meet or exceed RoHS requirements

The substitute part 165X02689XE meets all mandatory electrical and mechanical compatibility criteria. Variations in cable exit angle (45° versus 180°) and plating material (Nickel versus Blue Chromate) represent design alternatives that may be selected based on specific application requirements, but do not disqualify the part from substitution consideration when mechanical fit and electrical function are preserved.

Parameter Comparison

Engineering Selection Recommendations

Both the DEFME-101 and 165X02689XE maintain active product status with full regulatory compliance. The DEFME-101 carries RoHS Compliant certification, while the 165X02689XE meets the more stringent ROHS3 Compliant standard. Both components are rated MSL 1 (Unlimited) and include identical hardware configurations with 4-40 mating screws.

Selection between these parts should be based on application-specific requirements regarding cable exit geometry. The 180° exit angle of the DEFME-101 is suitable for straight-back cable routing, whereas the 45° exit angle of the 165X02689XE accommodates angled cable paths. Plating material differences (Blue Chromate versus Nickel) reflect corrosion resistance and environmental exposure considerations specific to the intended application environment.

Frequently Asked Questions (FAQ)

Q: Can the 165X02689XE directly replace the DEFME-101 in existing assemblies?

A: Mechanical and electrical compatibility is maintained. The primary design difference is the cable exit angle: 180° (DEFME-101) versus 45° (165X02689XE). Physical space constraints and cable routing geometry must be evaluated for your specific application before substitution.

Q: Are there compatibility differences between 9-position and HD15-position D-Sub configurations?

A: Both parts are specified as compatible with 9pos and HD15pos D-Sub sizes. Shell size E accommodates both configurations. Verify that your specific connector shell matches the E size specification.

Q: What is the significance of the plating material difference?

A: The DEFME-101 uses Blue Chromate plating, while the 165X02689XE uses Nickel plating. Both provide corrosion resistance. Selection depends on environmental exposure, temperature cycling, and humidity conditions in your application.

Q: Do both parts meet current environmental compliance standards?

A: Yes. The DEFME-101 is RoHS Compliant. The 165X02689XE meets ROHS3 Compliant and REACH Unaffected standards, representing alignment with current regulatory requirements.

Q: Are the mating screw specifications identical?

A: Yes. Both parts include 4-40 mating screws as part of the assembly hardware and strain relief configuration.
