Engineering Selection Recommendations

Both the TE Connectivity 3-5499141-0 and 3M N3433-5303RB are active products with equivalent connector interface standards and matching core electrical and mechanical specifications. Selection between these parts is based on the following engineering criteria:

TE Connectivity 3-5499141-0:

• ROHS3 Compliant certification
• Operating temperature range: -65°C ~ 105°C
• Current rating: 1A per Contact
• Voltage rating: 250VAC
• Contact post length: 0.110" (2.79mm)
• Insulation height: 0.315" (8.00mm)
• Tray packaging

3M N3433-5303RB:

• RoHS Compliant certification
• Operating temperature range: -55°C ~ 105°C
• Current rating: 1.75A per Contact
• Contact post length: 0.155" (3.94mm)
• Insulation height: 0.340" (8.64mm)
• Bulk packaging
• Higher contact finish thickness on post: 200.0µin (5.08µm) versus 100.0µin (2.54µm)

Selection should account for application-specific requirements regarding operating temperature extremes, current capacity, and PCB layout constraints related to contact post length and insulation height variations.

Frequently Asked Questions (FAQ)

Q: Can the 3M N3433-5303RB directly replace the TE Connectivity 3-5499141-0 in existing designs?

A: Direct replacement is possible for applications where the operating temperature range of -55°C ~ 105°C is acceptable and where the increased contact post length (0.155" versus 0.110") and insulation height (0.340" versus 0.315") do not create PCB layout conflicts. Both connectors share identical mating pitch, row spacing, shrouding configuration, and fastening mechanisms.

Q: What are the key differences between these two connector headers?

A: The primary differences are contact post length, insulation height, operating temperature minimum, current rating, and contact material composition. The 3M part offers higher current capacity (1.75A versus 1A) and thicker post plating (200.0µin versus 100.0µin). The TE Connectivity part operates at lower temperatures (-65°C minimum versus -55°C).

Q: Are both parts RoHS compliant?

A: Yes. The TE Connectivity 3-5499141-0 is ROHS3 Compliant, and the 3M N3433-5303RB is RoHS Compliant. Both meet regulatory requirements for hazardous substance restrictions.

Q: What is the significance of the different contact post lengths?

A: Contact post length affects solder joint depth and PCB hole engagement. The TE Connectivity part has a shorter post (0.110"), while the 3M part has a longer post (0.155"). PCB design must accommodate the selected connector's post length to ensure proper solder joint formation and mechanical stability.

Q: Do these connectors have different insulation materials?

A: Yes. The TE Connectivity part does not specify insulation material composition. The 3M N3433-5303RB uses Polycyclohexylenedimethylene Terephthalate (PCT), Polyester, and Glass Filled materials. Both achieve UL94 V-0 flammability rating.

Q: What packaging options are available?

A: The TE Connectivity 3-5499141-0 is supplied in Tray packaging, while the 3M N3433-5303RB is supplied in Bulk packaging. Packaging selection may affect inventory management and component handling procedures.

Q: Are both parts REACH compliant?

A: Yes. Both the TE Connectivity 3-5499141-0 and 3M N3433-5303RB have REACH Unaffected status, indicating compliance with REACH regulations.

Q: What is the voltage rating difference between these parts?

A: The TE Connectivity 3-5499141-0 specifies a voltage rating of 250VAC. The 3M N3433-5303RB does not provide a specified voltage rating in the available documentation. Applications requiring explicit voltage specifications should reference the TE Connectivity part or obtain additional technical documentation from 3M.
