3M 3793-5003 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 3793-5003 is a through-hole, right-angle rectangular connector header with 10 positions at 2.54mm pitch. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. The connector features shrouded 4-wall construction with male pins, solder termination, and push-pull fastening. Substitutes must maintain electrical and mechanical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3793-5003 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Pitch: 10 positions at 0.100" (2.54mm) mating pitch with 2-row configuration
• Mounting & Orientation: Through-hole, right-angle mounting
• Shrouding: Shrouded 4-wall construction
• Termination Method: Solder termination
• Electrical Performance: Current rating and operating temperature range
• Compliance: UL94 V-0 flammability rating and RoHS status

The following parts meet these substitution criteria:

1. D3793-5002-AR (3M, D3000 Series) - Active status, RoHS compliant
2. N3793-5002RB (3M, 3000 Series) - Active status, RoHS compliant
3. 71922-010LF (Amphenol ICC/FCI, Quickie™ Series) - Active status, RoHS compliant
4. CWN-501-10-0000 (CW Industries, CWN Series) - Active status, RoHS compliant

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: D3793-5002-AR or N3793-5002RB

Both 3M alternatives maintain the original design lineage while offering active product status and RoHS compliance. D3793-5002-AR is packaged in trays and represents the manufacturer's recommended upgrade path. N3793-5002RB is available in bulk packaging and maintains compatibility with the original 3000 series footprint. Both parts share identical electrical and mechanical specifications with the obsolete 3793-5003.

Secondary Recommendation: 71922-010LF

The Amphenol ICC Quickie™ series connector provides cross-manufacturer compatibility with active production status and RoHS compliance. This option is suitable for applications where multi-source qualification is required. The contact material differs (phosphor bronze vs. copper alloy), but electrical performance remains equivalent.

Alternative Consideration: CWN-501-10-0000

The CW Industries CWN series offers extended operating temperature range (-55°C ~ 125°C) and ROHS3 compliance. This connector features circular contacts instead of square contacts and employs latch lock/eject hooks fastening. Current rating is specified at 1A versus 1.75A for the original part. This option is suitable only for applications where the lower current rating and different contact geometry are acceptable.

Frequently Asked Questions (FAQ)

Q: Can D3793-5002-AR directly replace 3793-5003 in existing designs?

A: Yes. D3793-5002-AR maintains identical mating pitch (0.100"), position count (10), row configuration (2), mounting type (through-hole right-angle), and shrouding (4-wall). The primary differences are contact post length (0.112" vs. 0.155") and contact finish thickness on the post. These differences do not affect electrical or mechanical compatibility.

Q: What is the difference between N3793-5002RB and D3793-5002-AR?

A: Both are 3M products with identical electrical and mechanical specifications. The primary differences are packaging (bulk vs. tray) and series designation (3000 vs. D3000). N3793-5002RB is available in higher inventory quantities.

Q: Is 71922-010LF compatible with existing PCB footprints designed for 3793-5003?

A: Yes. The Amphenol ICC 71922-010LF maintains the same 0.100" (2.54mm) mating pitch, 10-position 2-row configuration, and through-hole right-angle mounting. Minor dimensional variations exist in contact length and insulation height, but these do not affect PCB footprint compatibility. The contact shape differs (square vs. square in original, but this part has square contacts), and the insulation color is gray instead of black.

Q: Why is CWN-501-10-0000 listed as a substitute if the current rating is lower?

A: CWN-501-10-0000 meets the core substitution criteria for connector type, position count, pitch, mounting, and shrouding. However, the 1A current rating is lower than the original 1.75A specification. This part is suitable only for applications where the actual current draw does not exceed 1A.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts are RoHS compliant or ROHS3 compliant. The original 3793-5003 is RoHS non-compliant, making RoHS-compliant substitutes necessary for new designs subject to RoHS regulations.

Q: What packaging options are available for these substitutes?

A: D3793-5002-AR is supplied in trays, N3793-5002RB in bulk, 71922-010LF in tubes, and CWN-501-10-0000 in unspecified packaging. Packaging selection should align with production volume and handling requirements.
