3M 3793-5205 Equivalent & Substitute Parts

Part Overview

The 3M 3793-5205 is an active rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This shrouded 4-wall header features 10 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. The part is manufactured with wire wrap termination and latch lock/eject hook fastening. Identifying equivalent and substitute parts is necessary when addressing inventory constraints, packaging requirements, or termination method compatibility in production environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3M 3793-5205 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 10 positions in 2 rows
• Pitch Spacing: 0.100" (2.54mm) mating pitch and row spacing
• Mounting Method: Through hole, right angle orientation
• Shrouding Design: Shrouded 4-wall construction
• Electrical Performance: 1.75A current rating, -55°C to 105°C operating range
• Material & Compliance: Copper alloy contacts, PCT/polyester/glass-filled insulation, UL94 V-0 rated, RoHS compliant

The substitute part N3793-5002RB maintains all critical mechanical and electrical parameters. Differences exist only in termination method (solder vs. wire wrap), fastening type (push-pull vs. latch lock/eject hooks), contact post length, and packaging format. These differences do not affect mating compatibility or electrical performance in applications where the termination method is compatible with the PCB design.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 3793-5205 and N3793-5002RB are active products with identical RoHS compliance and REACH unaffected status. Selection between these parts depends on termination compatibility with the target PCB assembly process:

• 3793-5205: Select this part number for wire wrap termination applications where post length of 0.610" (15.49mm) and tin-lead finish are required.
• N3793-5002RB: Select this part number for solder termination applications where post length of 0.112" (2.84mm) and tin finish are compatible with the PCB design.

Both parts maintain identical mating interface dimensions, electrical ratings, and environmental specifications. The choice between latch lock/eject hooks and push-pull fastening is determined by the connector housing design used in the application.

Frequently Asked Questions (FAQ)

Q: Can N3793-5002RB be used as a direct replacement for 3793-5205?

A: N3793-5002RB is mechanically and electrically compatible at the mating interface. However, substitution requires compatibility with the solder termination method and push-pull fastening type. The shorter post length (0.112" vs. 0.610") is designed for surface-mount or solder-tail applications, not wire wrap.

Q: What is the primary difference between these two part numbers?

A: The primary differences are termination method (wire wrap vs. solder), fastening type (latch lock/eject hooks vs. push-pull), and contact post length. All mating interface parameters, electrical ratings, and environmental specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes, both 3793-5205 and N3793-5002RB are RoHS compliant and REACH unaffected.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 105°C.

Q: Can these parts be used interchangeably in the same connector housing?

A: Mating compatibility is maintained due to identical pitch spacing (0.100"), position count (10), row configuration (2 rows), and contact geometry. However, the different fastening types (latch lock/eject hooks vs. push-pull) may require different housing designs.

Q: What is the current rating for both parts?

A: Both parts are rated for 1.75A per contact.
