3M 3793-6203 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The 3M 3793-6203 is a through-hole rectangular connector header with 10 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector features shrouded 4-wall construction with solder termination and latch lock/eject hook fastening. The part is classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the 3M 3793-6203 is determined by strict equivalence in the following parameters: connector type (header), contact type (male pin), number of positions (10), number of rows (2), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting type (through hole), shrouding (shrouded 4-wall), termination (solder), and operating temperature range (-55°C ~ 105°C). Parts meeting these criteria are classified as direct substitutes regardless of manufacturer, series designation, or packaging format.

Secondary considerations include fastening type (latch lock/eject hooks versus push-pull), contact material composition, contact finish specifications, and regulatory compliance status. Parts with identical core electrical and mechanical parameters but differing in these secondary attributes remain functionally compatible within the specified operating envelope.

Engineering Selection Recommendations

For applications requiring direct replacement of the obsolete 3M 3793-6203, the following active alternatives are available:

3M N3793-6203RB is the direct 3M equivalent with identical mechanical and electrical specifications. This part maintains the same series designation (3000), fastening type (latch lock/eject hooks, short), and operating temperature range. The primary advantage is improved current rating (1.75A versus 1A) and RoHS compliance. Packaging is bulk format.

3M D3793-6002-AR and 3M N3793-6002RB represent alternative 3M solutions with modified fastening mechanisms (push-pull instead of latch lock/eject hooks). Both maintain core electrical and mechanical compatibility with enhanced current ratings (1.75A). D3793-6002-AR is supplied in tray packaging with ROHS3 compliance, while N3793-6002RB is bulk packaged with standard RoHS compliance.

TE Connectivity 499160-1 and 499374-1 provide cross-manufacturer substitution within the AMP-Latch series. Both maintain latch lock/eject hook fastening and full mechanical compatibility. The 499374-1 offers extended operating temperature range (-65°C ~ 105°C) and specified voltage rating (250VAC). Both are non-compliant or not applicable for RoHS.

TE Connectivity 5499374-1 is the RoHS-compliant variant of 499374-1, supplied in tray packaging with identical electrical and mechanical specifications.

Amphenol ICC 71918-210LF and 71918-210RLF (Quickie™ series) provide alternative cross-manufacturer solutions with RoHS compliance. Both maintain full mechanical compatibility and latch lock/eject hook fastening. Operating temperature and current rating specifications are not provided for these parts.

For new designs or procurement requiring RoHS compliance, N3793-6203RB, D3793-6002-AR, N3793-6002RB, 5499374-1, 71918-210LF, or 71918-210RLF are suitable selections. For applications with extended temperature requirements (-65°C), 499374-1 or 5499374-1 are specified.

Frequently Asked Questions (FAQ)

Q: Can the 3M 3793-6203 be directly replaced with N3793-6203RB?

A: Yes. N3793-6203RB is the active equivalent with identical connector type, contact type, position count, pitch, row spacing, mounting type, shrouding, termination, and operating temperature range. The primary differences are improved current rating (1.75A versus 1A), RoHS compliance, and active product status.

Q: What is the difference between latch lock/eject hooks and push-pull fastening?

A: Latch lock/eject hooks provide mechanical retention through spring-loaded latching mechanisms. Push-pull fastening uses a different engagement method. Both fastening types maintain electrical and mechanical compatibility within the 2.54mm pitch, 10-position, 2-row header specification. Selection depends on mating connector design and application requirements.

Q: Are TE Connectivity and Amphenol ICC parts compatible with 3M headers?

A: Yes. 499160-1, 499374-1, 5499374-1, 71918-210LF, and 71918-210RLF maintain identical core specifications: 10 positions, 2 rows, 0.100" (2.54mm) pitch, shrouded 4-wall construction, through-hole mounting, and solder termination. Cross-manufacturer compatibility is established through these shared electrical and mechanical parameters.

Q: What packaging options are available?

A: Substitute parts are supplied in bulk, tray, or tube packaging. N3793-6203RB and N3793-6002RB are bulk packaged. D3793-6002-AR and 5499374-1 are tray packaged. 71918-210LF and 71918-210RLF are tube packaged. Packaging selection does not affect electrical or mechanical compatibility.

Q: Which substitute parts have RoHS compliance?

A: N3793-6203RB, D3793-6002-AR, N3793-6002RB, 5499374-1, 71918-210LF, and 71918-210RLF are RoHS compliant. The original 3793-6203 is non-compliant. 499160-1 and 499374-1 are non-compliant or not applicable for RoHS.

Q: What is the current rating difference between substitute parts?

A: The original 3793-6203 is rated at 1A. N3793-6203RB, D3793-6002-AR, and N3793-6002RB are rated at 1.75A. 499160-1 and 499374-1 are rated at 1A per contact. 71918-210LF and 71918-210RLF do not specify current rating. Selection should be based on application current requirements.

Q: Are there temperature range differences?

A: The original 3793-6203 operates from -55°C to 105°C. N3793-6203RB, D3793-6002-AR, and N3793-6002RB maintain this range. 499374-1 and 5499374-1 extend to -65°C to 105°C. 71918-210LF and 71918-210RLF do not specify operating temperature. Applications requiring extended low-temperature operation should specify 499374-1 or 5499374-1.
