Engineering Selection Recommendations

For new designs and production transitions, the 3M D3429-6002-AR and 3M N3429-6002RB are preferred substitutes due to active product status and RoHS compliance. The D3429-6002-AR offers ROHS3 compliance with higher current rating (1.75A) and improved contact finish specifications. The N3429-6002RB provides RoHS compliance with equivalent electrical performance and is available in bulk packaging.

The 3M 3429-6002 remains functionally equivalent but carries obsolete status classification. The TE Connectivity 5499374-6 is a cross-manufacturer alternative with active status and extended operating temperature range (-65°C ~ 105°C), suitable for applications requiring broader thermal performance.

For applications with existing RoHS non-compliant requirements, the 3429-6002 maintains full electrical and mechanical compatibility with the original 3429-6202-UG.

Frequently Asked Questions (FAQ)

Q: Can the 3M D3429-6002-AR directly replace the 3429-6202-UG in existing assemblies?

A: Yes. The D3429-6002-AR maintains identical pitch (0.100"), position count (26), row configuration (2 rows), mounting type (through hole), and shrouding (4-wall). The higher current rating (1.75A vs. 1A) and improved RoHS compliance make it suitable for direct substitution.

Q: What is the difference between fastening types listed for these connectors?

A: The 3429-6202-UG uses latch lock/eject hooks (short), while the 3429-6002, D3429-6002-AR, and N3429-6002RB use push-pull fastening. Both fastening types are compatible with standard mating connectors designed for 0.100" pitch 26-position headers.

Q: Does the TE Connectivity 5499374-6 require different PCB footprint design?

A: The 5499374-6 maintains the same 0.100" pitch and 2-row configuration. However, contact post length differs (0.155" vs. 0.112"), which may affect solder joint geometry and PCB trace routing. Footprint compatibility should be confirmed against specific PCB design requirements.

Q: Are there packaging considerations when selecting a substitute?

A: Yes. The 3429-6002 and N3429-6002RB are supplied in bulk packaging, while D3429-6002-AR and 5499374-6 are supplied in tray packaging. Bulk packaging is suitable for high-volume assembly operations, while tray packaging provides better component protection during handling and storage.

Q: Which substitute offers the best compliance profile for new product development?

A: The 3M D3429-6002-AR provides ROHS3 compliance and active product status, making it the optimal choice for new designs. The N3429-6002RB offers RoHS compliance as an alternative 3M option with active status.
