Overview: Building Commercial Accessory Part Numbers From Scratch “What backshell part number should I use for this connector?” Select Series based on main required function Select “Basic Part Number” based on additional required features Use the “Connector Designator” to Indicate the series of connector the backshell is for Select “Angle and Profile based on routing requirements Flesh out other variables manually or use “QwikCreate” on-line
Step (1): Select Series Based on Function Environmental Backshell Strain Relief Clamp Protective Cover EMI Banding Backshell EMI/RFI Backshell
(2) Select “Basic Part Number” Based on Additional Requirements/Features NOTE: Use the Series and Basic Part Number Combination (XXX-XXX) when searching on web
(3) Select “Connector Designator” Based on the Connector Series the Part is For HINT: Just Memorize the Common Designators
(4) Select the “Angle and Profile” Based on Cable Routing Requirements HINT: Again, just memorize the most common codes
(5) Select Other Variables Manually or… Use QwikCreate QwikCreate: Internet-Based Automated Part Number Development The remaining variables (finish, size, etc.) are all straightforward. Either use the catalog or finish out the part number with QwikCreate: Generate printable document with all relevant dimensional data Link to catalog page for additional information Automatically select for Style 2 cable entry
Rectangular Backshells Use The Same System and Logic MIL-C-24308 MIL-C-81659 MIL-C-83733 ARINC Series 600 MIL-DTL-83513 Cannon Series 400 MIL-C-83527/A

Importance of Understanding What the Connector Part Numbers Mean Too Interconnect Components All Go Together If you can determine the connector series, size and plating…. You can easily match it to an appropriate accessory But mismatched parts = trouble Potential for incorrect fit, dissimilar plating, or other problems
