Substitute Part Grouping Explanation

Substitution for the 3793-5002UG is determined by the following critical parameters:

Connector type (Header), contact type (Male Pin), and mating pitch (0.100" / 2.54mm)
Position count (10) and row configuration (2 rows)
Mounting style (Through Hole, Right Angle)
Shrouding configuration (Shrouded - 4 Wall)
Termination method (Solder)
Operating temperature range (-55°C ~ 105°C)
Flammability rating (UL94 V-0)

Substitute parts are grouped into two categories:

Category 1: 3M Direct Successors — Parts from 3M's active product lines that maintain identical electrical and mechanical specifications with improved compliance status.

Category 2: Amphenol ICC (FCI) Quickie™ Series — Cross-manufacturer alternatives with compatible mating pitch, position count, and mounting configuration. These parts feature circular contact geometry and alternative fastening mechanisms while maintaining functional compatibility.

Engineering Selection Recommendations

For RoHS-compliant applications: Select D3793-5002-AR, N3793-5002RB, 65823-001LF, or 65823-049LF. These parts meet RoHS compliance requirements and are suitable for regulated industries and modern manufacturing standards.

For direct 3M product line continuity: D3793-5002-AR and N3793-5002RB are active 3M products that maintain the original connector geometry and specifications. D3793-5002-AR is packaged in trays, while N3793-5002RB is supplied in bulk.

For cross-manufacturer compatibility: The Amphenol ICC (FCI) Quickie™ series (65823-001LF, 65823-003, 65823-049LF, 65823-378LF) provides functional equivalence with alternative contact geometry and fastening mechanisms. These parts are suitable when cross-manufacturer sourcing is acceptable.

For fastening mechanism requirements: Push-Pull fastening is available in 3793-5002UG, D3793-5002-AR, N3793-5002RB, and 65823-362. Latch Lock/Eject Hooks fastening is available in 65823-049, 65823-049LF, 65823-051, 65823-366, and 65823-378LF.

Frequently Asked Questions (FAQ)

Q: Can I substitute the obsolete 3793-5002UG with an active 3M part?

A: Yes. D3793-5002-AR and N3793-5002RB are active 3M products with identical electrical and mechanical specifications. Both maintain the same pitch (2.54mm), position count (10), mounting style (through-hole right-angle), and shrouding configuration. D3793-5002-AR is RoHS compliant and supplied in trays; N3793-5002RB is RoHS compliant and supplied in bulk.

Q: What are the differences between 3M and Amphenol ICC (FCI) substitute options?

A: 3M direct successors (D3793-5002-AR, N3793-5002RB) maintain square contact geometry and identical insulation height. Amphenol ICC (FCI) Quickie™ series parts feature circular contact geometry, different insulation height (0.305" vs. 0.340"), and alternative fastening mechanisms. All maintain the critical 2.54mm pitch and 10-position, 2-row configuration.

Q: Are there RoHS compliance differences among the substitutes?

A: Yes. D3793-5002-AR, N3793-5002RB, 65823-001LF, and 65823-049LF are RoHS compliant. The original 3793-5002UG, 65823-003, 65823-049, 65823-051, 65823-362, and 65823-366 are RoHS non-compliant. Select RoHS-compliant parts for applications requiring regulatory compliance.

Q: What packaging options are available?

A: D3793-5002-AR is supplied in trays. N3793-5002RB, 65823-001LF, 65823-003, 65823-049, 65823-049LF, 65823-051, 65823-362, 65823-366, and 65823-378LF are supplied in bulk. 65823-378LF is also available in trays.

Q: Do all substitute parts have the same current rating?

A: The 3M parts (3793-5002UG, D3793-5002-AR, N3793-5002RB) are rated at 1.75A. Current ratings for Amphenol ICC (FCI) Quickie™ series parts are not specified in the provided data.

Q: What is the difference between Push-Pull and Latch Lock/Eject Hooks fastening?

A: Push-Pull fastening uses a simple push-to-connect, pull-to-disconnect mechanism. Latch Lock/Eject Hooks fastening provides positive locking with eject hooks for secure connection and controlled disconnection. Select based on application requirements for connection security and ease of service.

Q: Can I use parts with different contact post lengths interchangeably?

A: Contact post length affects PCB penetration depth. Standard length (0.105" / 2.67mm) and extended length (0.150" / 3.81mm) options are available. Selection depends on PCB thickness and solder joint requirements. Verify compatibility with your PCB design before substitution.
