Engineering Selection Recommendations

For RoHS Compliance Requirements:

N3793-2302RB (3M direct substitute) provides RoHS compliance while maintaining the 3M 3000 series platform. This part is active and carries 1983 units in stock inventory.

For enhanced compliance posture, 2-5102321-1, 2-5499206-1, 5102321-1, 5499206-1, and 5499922-1 all carry ROHS3 certification. These TE Connectivity AMP-Latch parts offer extended temperature range (-65°C to 105°C) and are actively produced with substantial inventory availability.

For Legacy Non-Compliant Designs:

102321-1, 499206-1, and 499922-1 maintain RoHS non-compliant or not-applicable status, suitable for designs without compliance mandates. These parts remain in active production.

For Maximum Availability:

5499206-1 carries the highest inventory level at 500,200 units, followed by 5499922-1 at 3,557 units. Both are ROHS3 compliant and actively produced.

For Mechanical Compatibility:

N3793-2302RB maintains 3-wall shrouding identical to the original 3793-2602UG. All other substitutes employ 4-wall shrouding, which provides enhanced mechanical protection but may require PCB layout verification for mounting flange clearance.

Frequently Asked Questions (FAQ)

Q: Can I use a 4-wall shrouded connector as a direct replacement for the 3-wall shrouded 3793-2602UG?

A: Mechanically, 4-wall shrouding is compatible with 2.54mm pitch and 10-position configurations. However, the increased shroud height and flange dimensions require verification against your PCB layout and mating connector cavity. N3793-2302RB provides identical 3-wall shrouding for direct mechanical interchange.

Q: What is the difference between the TE Connectivity AMP-Latch and Amphenol ICC Quickie™ series?

A: Both series meet the core electrical and mechanical parameters of 2.54mm pitch, 10-position headers with through-hole solder termination. AMP-Latch parts specify 250VAC voltage rating and 1A current per contact. Quickie™ series (53611-G10-6LF) does not specify voltage or current ratings in the provided data. Contact length specifications differ slightly between series.

Q: Are there RoHS compliance differences between substitute options?

A: Yes. N3793-2302RB is RoHS compliant. TE Connectivity parts 2-5102321-1, 2-5499206-1, 5102321-1, 5499206-1, and 5499922-1 carry ROHS3 certification. Parts 102321-1, 499206-1, and 499922-1 are either non-compliant or not applicable. Select based on your design's compliance requirements.

Q: What packaging options are available?

A: N3793-2302RB and 499206-1 and 5499922-1 are supplied in bulk packaging. All TE Connectivity AMP-Latch parts except 499206-1 and 5499922-1 are supplied in tray packaging. 53611-G10-6LF is supplied in tray. Confirm packaging requirements with your procurement process.

Q: Does the extended temperature range of TE Connectivity parts (-65°C to 105°C) affect compatibility?

A: No. The extended lower temperature limit of -65°C is a superset of the original -55°C specification and does not affect electrical or mechanical compatibility. This represents an enhancement for applications requiring operation at lower temperatures.

Q: What are the contact finish differences between substitute parts?

A: The original 3793-2602UG specifies gold mating finish at 15.0µin thickness with tin-lead post finish. N3793-2302RB maintains gold mating finish but increases thickness to 30.0µin and changes post finish to tin. TE Connectivity parts specify gold or gold-palladium mating finish at 30.0µin with tin or tin-lead post finish. Amphenol ICC specifies gold or gold GXT™ mating finish. All finishes are compatible with standard PCB soldering processes.
