Key Parameters

Substitute Part Grouping Explanation

The DF33C-6P-3.3DSA(24) is qualified as a direct substitute based on the following critical parameters that determine functional compatibility:

• Connector Type & Configuration: Both parts are headers with identical 6-position, single-row configuration
• Pitch Specification: Matching 0.130" (3.30mm) mating pitch ensures mechanical and electrical compatibility
• Contact Type: Both feature male pin contacts
• Mounting Method: Through-hole mounting is consistent across both parts
• Termination: Solder termination is identical
• Electrical Ratings: Both support 5A current rating and 500V voltage rating
• Manufacturer: Both manufactured by Hirose Electric Co Ltd, ensuring design continuity

The substitution is based on maintaining identical electrical performance, mechanical fit, and board-level integration requirements. The DF33C variant represents the active-production equivalent within the same product family.

Parameter Comparison
