Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical 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, right angle), shrouding (shrouded 4-wall), contact length mating (0.240"/6.10mm), insulation height, operating temperature range (-55°C to 105°C minimum), current rating (1.75A minimum), material flammability (UL94 V-0), and contact finish mating (gold).

Substitute parts are grouped into two categories:

Direct 3M Equivalents (Series 3000): Parts N3793-5302RB and N3793-5002RB maintain identical electrical and mechanical specifications to the 3793-5302 with active product status and improved compliance certifications.

Alternative Manufacturer Equivalents: TE Connectivity AMP-Latch series (5499345-1, 102322-1, 2-5499141-1, 499141-1, 499786-1, 5102322-1) and Amphenol CONEC (141A10919X) provide functional equivalence with minor variations in contact post length, insulation material composition, and fastening mechanism (push-pull versus latch lock/eject hooks).

Engineering Selection Recommendations

Direct 3M Replacement (Preferred for Pin-Compatible Designs):

N3793-5302RB is the direct active equivalent to the 3793-5302. This part maintains identical mechanical dimensions, contact geometry, and electrical ratings while offering RoHS compliance and active product status. Packaging is available in tray format with 1257 units in stock.

N3793-5002RB provides an alternative 3M option with push-pull fastening instead of latch lock/eject hooks. This part is available in bulk packaging with 1302 units in stock and carries RoHS compliance.

3M Series D3000 Alternative:

D3793-5002-AR represents 3M's newer D-series platform with identical core specifications. This part features push-pull fastening, brass contact material, and reduced gold plating thickness on mating contacts (10.0µin versus 30.0µin). RoHS compliance is confirmed. Selection of this part requires verification that reduced contact finish thickness meets application requirements.

TE Connectivity AMP-Latch Series:

The TE Connectivity AMP-Latch series (5499345-1, 102322-1, 2-5499141-1, 499141-1, 499786-1, 5102322-1) provides functional equivalence with the following considerations:

Insulation height is reduced to 0.315" (8.00mm) versus 0.340" (8.64mm) on the 3793-5302
Contact post length varies between 0.110" (2.79mm) and 0.155" (3.94mm)
Current rating is specified as 1A per contact versus 1.75A on the original part
Operating temperature range extends to -65°C minimum
Voltage rating is specified at 250VAC

These dimensional and electrical differences require PCB layout verification before substitution.

Amphenol CONEC Alternative:

141A10919X offers functional equivalence with the following distinctions:

Insulation height is 0.335" (8.51mm)
Contact mating length is 0.236" (6.00mm) versus 0.240" (6.10mm)
Contact post length is 0.114" (2.90mm)
Insulation material is polybutylene terephthalate (PBT) glass-filled versus polycyclohexylenedimethylene terephthalate (PCT) on the 3793-5302
Insulation color is gray versus black
Current rating is 1A versus 1.75A
Operating temperature range is not specified
ROHS3 compliance is confirmed

Compliance Considerations:

For applications requiring RoHS compliance, N3793-5302RB, N3793-5002RB, D3793-5002-AR, 2-5499141-1, 141A10919X, and 5102322-1 are suitable. Parts 102322-1, 499141-1, and 499786-1 carry non-compliant or not-applicable RoHS status and are restricted in regulated markets.

For applications requiring REACH compliance, N3793-5302RB, N3793-5002RB, D3793-5002-AR, 2-5499141-1, 141A10919X, and 5102322-1 carry confirmed REACH unaffected or compliant status.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 3793-5302 with N3793-5302RB directly on my PCB?

A: Yes. N3793-5302RB maintains identical mechanical dimensions, contact geometry, pitch spacing, and electrical ratings. No PCB layout modifications are required. This is the recommended direct replacement.

Q: What is the difference between N3793-5302RB and N3793-5002RB?

A: Both parts are 3M Series 3000 headers with identical electrical and mechanical specifications. The primary difference is the fastening mechanism: N3793-5302RB uses latch lock/eject hooks (long), while N3793-5002RB uses push-pull fastening. N3793-5002RB is available in bulk packaging versus tray for N3793-5302RB.

Q: Can I use TE Connectivity 5499345-1 as a substitute?

A: Functional substitution is possible with design verification. The 5499345-1 has a reduced insulation height (0.315" versus 0.340"), shorter contact post length (0.110" versus 0.112"), and lower current rating (1A per contact versus 1.75A). PCB layout must be verified to confirm clearance and trace routing compatibility. Current capacity must be re-evaluated for your application.

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

A: Latch lock/eject hooks provide positive mechanical engagement with audible/tactile feedback and require deliberate unlatching. Push-pull fastening allows mating and unmating with axial force only, without latching mechanism. Selection depends on application requirements for connector retention and ease of service.

Q: Are all substitute parts RoHS compliant?

A: No. Parts 102322-1, 499141-1, and 499786-1 carry non-compliant or not-applicable RoHS status. For regulated applications, use N3793-5302RB, N3793-5002RB, D3793-5002-AR, 2-5499141-1, 141A10919X, or 5102322-1.

Q: What packaging options are available?

A: 3M parts are available in tray (N3793-5302RB, D3793-5002-AR) and bulk (N3793-5002RB) formats. TE Connectivity parts are available in tray (5499345-1, 102322-1, 2-5499141-1, 5102322-1) and bulk (499141-1, 499786-1) formats. Amphenol CONEC 141A10919X is available in bulk packaging.

Q: Can I substitute based on current rating alone?

A: No. Current rating is one of multiple critical parameters. Pitch spacing, number of positions, mounting type, shrouding, contact geometry, and insulation height must all match or be verified for compatibility. Substitution requires equivalence across all specified parameters.

Q: What is the significance of contact finish thickness?

A: Contact finish thickness affects durability and mating cycle life. The 3793-5302 specifies 30.0µin (0.76µm) gold on mating contacts. D3793-5002-AR specifies 10.0µin (0.25µm), which is thinner. TE Connectivity parts specify 30.0µin or 15.0µin depending on part number. Thinner finishes may reduce contact life in high-cycle applications.

Q: Is the Amphenol 141A10919X a direct substitute?

A: The 141A10919X provides functional equivalence with dimensional and material variations. Insulation height is 0.335" (8.51mm), contact mating length is 0.236" (6.00mm), and insulation material is PBT glass-filled. Operating temperature range is not specified. PCB layout and thermal performance must be verified before substitution.
