3M 3793-6205 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3793-6205 is a shrouded rectangular connector header designed for through-hole mounting with 10 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This component features wire wrap termination and is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the 3793-6205 is determined by the following critical parameters that must remain constant:

Connector type (Header)
Contact type (Male Pin)
Position count (10 positions in 2 rows)
Mating pitch (0.100" / 2.54mm)
Row spacing (0.100" / 2.54mm)
Shrouding configuration (Shrouded - 4 Wall)
Mounting method (Through Hole)
Operating temperature range (-55°C ~ 105°C)
Flammability rating (UL94 V-0)
Moisture sensitivity level (MSL 1)

The two substitute parts identified—D3793-6002-AR and N3793-6002RB—maintain these core parameters while differing in termination method (solder vs. wire wrap), contact material composition, contact finish specifications, and product status (active vs. obsolete).

Engineering Selection Recommendations

Both D3793-6002-AR and N3793-6002RB are active production alternatives to the obsolete 3793-6205. Selection between these substitutes depends on application-specific requirements:

D3793-6002-AR is classified as ROHS3 Compliant and is packaged in trays, making it suitable for applications requiring enhanced environmental compliance and controlled inventory management. This part operates at 1.75A current rating with brass contact material.

N3793-6002RB maintains RoHS Compliance and is supplied in bulk packaging. This part also operates at 1.75A current rating and uses copper alloy contact material, matching the material composition of the original 3793-6205.

Both substitutes employ solder termination rather than wire wrap, requiring PCB design modifications to accommodate the different termination method. Both maintain the same mating pitch, row spacing, shrouding configuration, and operating temperature range as the original part.

Frequently Asked Questions (FAQ)

Q: Can D3793-6002-AR and N3793-6002RB be used interchangeably with 3793-6205?

A: Both parts maintain identical mating pitch (0.100" / 2.54mm), row spacing, position count, shrouding, and operating temperature range. However, the termination method differs: the original uses wire wrap while both substitutes use solder termination. PCB layout modifications are required to accommodate solder pads instead of wire wrap posts.

Q: What is the primary difference between D3793-6002-AR and N3793-6002RB?

A: The primary differences are contact material (brass vs. copper alloy), packaging format (tray vs. bulk), and compliance certifications (ROHS3 vs. RoHS). Both provide identical electrical performance at 1.75A current rating and maintain the same mechanical interface.

Q: Why does the current rating increase from 1A to 1.75A in the substitute parts?

A: The current rating difference reflects the electrical characteristics of the solder termination design versus the wire wrap design. Both substitute parts are rated for 1.75A continuous current.

Q: Are there packaging considerations when selecting between these substitutes?

A: D3793-6002-AR is supplied in trays, suitable for automated assembly and controlled dispensing. N3793-6002RB is supplied in bulk packaging, suitable for manual assembly or high-volume applications where packaging format is less critical.

Q: Do both substitutes meet the same environmental and compliance standards?

A: Both substitutes maintain UL94 V-0 flammability rating, MSL 1 moisture sensitivity level, and operating temperature range of -55°C to 105°C. D3793-6002-AR is ROHS3 Compliant; N3793-6002RB is RoHS Compliant. Both are EAR99 classified with identical HTSUS codes.
