Engineering Selection Recommendations

Primary Recommendation: N3793-6002RB (3M)

The N3793-6002RB is the direct active equivalent from the original manufacturer. It maintains identical mechanical and electrical interface specifications while offering RoHS compliance and improved current rating (1.75A versus 1A). This part is available in bulk packaging with 1,819 units in stock.

Secondary Recommendation: D3793-6002-AR (3M)

The D3793-6002-AR represents the manufacturer-recommended upgrade path. It provides ROHS3 compliance and maintains full interface compatibility. The part is supplied in tray packaging with 1,589 units available. Contact material differs (brass versus copper alloy), and contact finish thickness on the post is reduced, but these variations do not affect substitution eligibility.

Alternative Recommendation: 71918-010LF (Amphenol ICC/FCI)

The 71918-010LF from the Quickie™ series offers an alternative from an established connector manufacturer. It maintains all critical interface parameters with push-pull fastening and UL94 V-0 rating. This part features phosphor bronze contacts with GXT™ gold finish and is available in tube packaging with 3,665 units in stock. RoHS compliance is confirmed.

CW Industries Options: CWN-350-10-0021, CWN-360-10-0021

CW Industries provides multiple substitutes with push-pull fastening compatible with the original design. CWN-350-10-0021 and CWN-360-10-0021 both maintain the required interface specifications with ROHS3 compliance. These parts feature circular contact geometry and phosphor bronze material. CWN-360 variants have extended contact post length (0.155" versus 0.090"), which may affect board-level clearance in constrained layouts.

CW Industries Latch Lock Options: CWN-351 and CWN-352 Series

CWN-351-10-0000, CWN-351-10-0021, CWN-352-10-0000, and CWN-352-10-0021 employ latch lock/eject hook fastening mechanisms instead of push-pull. These parts are electrically and mechanically compatible but require mating connector redesign to accommodate the different fastening interface. Selection of these variants is appropriate only when connector redesign is feasible.

Frequently Asked Questions (FAQ)

Q: Can N3793-6002RB directly replace 3793-6002 without PCB modification?

A: Yes. The N3793-6002RB maintains identical pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), number of positions (10), number of rows (2), shrouding (4-wall), and mounting type (through hole). No PCB layout changes are required.

Q: What is the difference between push-pull and latch lock fastening types?

A: Push-pull fastening (3793-6002, N3793-6002RB, D3793-6002-AR, 71918-010LF, CWN-350, CWN-360) uses a simple push-to-connect, pull-to-disconnect mechanism. Latch lock/eject hook fastening (CWN-351, CWN-352) requires a mating connector with corresponding hook features. Substitution between these fastening types requires mating connector redesign.

Q: Does the current rating difference between 1A and 1.75A affect substitution?

A: Higher current rating indicates improved capability. Parts rated 1.75A (N3793-6002RB, D3793-6002-AR) are suitable substitutes for applications requiring 1A or less. Substitution in the reverse direction is not appropriate.

Q: Are CW Industries parts electrically equivalent to 3M parts?

A: Yes. CW Industries rectangular connectors with matching pitch, position count, row spacing, shrouding, and fastening type are electrically and mechanically equivalent. Contact material and finish specifications differ but do not affect interface compatibility.

Q: What is the significance of contact finish thickness variations?

A: Contact finish thickness (measured in microinches or micrometers) affects contact durability and wear resistance. Variations in finish thickness do not preclude substitution provided the mating surface finish remains gold and the contact material maintains electrical conductivity specifications.

Q: Can 71918-010LF be used in applications requiring RoHS compliance?

A: Yes. The 71918-010LF is RoHS compliant. However, REACH status is listed as affected, which may require additional documentation for certain regulated markets.

Q: What packaging options are available for substitute parts?

A: Substitute parts are supplied in bulk, tray, or tube packaging. Bulk packaging (N3793-6002RB, CWN-351-10-0021, CWN-360-10-0021) is suitable for high-volume production. Tray packaging (D3793-6002-AR) accommodates moderate volumes. Tube packaging (71918-010LF) is appropriate for lower-volume applications.

Q: Are all substitute parts rated for -55°C to 105°C operation?

A: The original 3793-6002 is rated -55°C to 105°C. Most substitutes (N3793-6002RB, D3793-6002-AR, CW Industries parts) are rated -55°C to 125°C, providing extended temperature capability. The 71918-010LF does not specify operating temperature range in available documentation.

Q: What is the difference between contact shape (square versus circular)?

A: The original 3793-6002 features square contacts. Substitute parts from CW Industries (CWN series) employ circular contacts. Contact shape does not affect electrical performance or mating compatibility provided pitch and position count remain identical.
