DA-51210-1 Equivalent & Substitute Parts

Part Overview

The DA-51210-1 is a 15-position one-piece backshell connector manufactured by Cinch Connectivity Solutions, designed for D-Sub applications with 180° cable exit orientation. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. The backshell provides mechanical strain relief and environmental protection for D-Sub connector assemblies in round cable configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DA-51210-1 is determined by the following critical parameters:

• Number of Positions: Must be 15 to maintain connector compatibility
• Compatible Shell Size: Must be Size A for mechanical fit
• Compatible D-Sub Size: Must support 15pos and HD26pos configurations
• Cable Exit Angle: Must be 180° to match installation geometry
• Shielding Type: Must be unshielded to match electrical characteristics
• Accessory Type: Must be one-piece backshell construction
• Cable Type: Must accommodate round cable

The substitute part 165X10399XE meets all these critical parameters, with the primary difference being color (black versus gray) and material specification variance (PA6 Nylon 6 versus PA Nylon), neither of which affects functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 165X10399XE from Amphenol CONEC is a direct functional equivalent to the obsolete DA-51210-1. Both components share identical mechanical and electrical specifications for the critical parameters governing D-Sub backshell compatibility.

The 165X10399XE offers the advantage of active product status, ensuring continued availability and supply chain stability. Additionally, this substitute achieves ROHS3 compliance, whereas the original DA-51210-1 is non-compliant. Both parts maintain identical export classification (EAR99) and tariff codes (8538.90.8180).

The material specification difference (PA6 Nylon 6 versus PA Nylon) and color variation (black versus gray) do not impact functional performance in standard D-Sub backshell applications. Selection between these variants should be based on specific system requirements regarding color coding or material performance in the intended operating environment.

Frequently Asked Questions (FAQ)

Q: Can the 165X10399XE directly replace the DA-51210-1 in existing assemblies?

A: Yes. Both components are 15-position, Size A compatible backshells with 180° cable exit and unshielded construction. Mechanical and electrical compatibility is maintained.

Q: Does the color difference (gray to black) affect compatibility?

A: No. Color is a cosmetic parameter and does not affect electrical or mechanical function. Selection should be based on system color-coding requirements.

Q: What is the significance of the RoHS compliance difference?

A: The 165X10399XE achieves ROHS3 compliance while the DA-51210-1 is non-compliant. For applications subject to RoHS regulations, the substitute part provides regulatory alignment.

Q: Are there material performance differences between PA Nylon and PA6 Nylon 6?

A: Both materials are polyamide-based thermoplastics suitable for D-Sub backshell applications. Material selection should be verified against specific environmental conditions (temperature, humidity, chemical exposure) in the intended application.

Q: Is the 165X10399XE available in gray to match the original color?

A: The provided data specifies the 165X10399XE in black only. Color availability should be confirmed with the manufacturer or authorized distributor.

Q: Do both parts support the same D-Sub connector sizes?

A: Yes. Both the DA-51210-1 and 165X10399XE are compatible with 15-position and HD26-position D-Sub connectors in Size A shell configuration.
