Engineering Selection Recommendations

For RoHS-Compliant Applications: Select D3428-6002-AR or N3428-6002RB. Both are active 3M products with RoHS compliance. D3428-6002-AR offers RoHS Compliant status with push-pull fastening and higher current rating (1.75A). N3428-6002RB provides ROHS3 Compliant status with push-pull fastening and equivalent current rating (1.75A).

For Extended Temperature Range Applications: HARTING SEK Series parts (09185205912, 09185205914, 09185206912, 09185206914, 09185207912, 09185207914) support -55°C ~ 125°C operating temperature, exceeding the original 3428-6202UG specification of -55°C ~ 105°C. These parts are ROHS3 Compliant and REACH Unaffected.

For Direct Mechanical Compatibility: The original 3428-6202UG uses tin-lead post plating. All active substitutes use tin-only post plating. Contact length variations exist between 3M and HARTING options. Verify PCB footprint compatibility before selection.

For Production Continuity: All substitute parts maintain the core 20-position, 2-row, 2.54mm pitch configuration with through-hole solder termination and 4-wall shrouding. Fastening type differs: original uses latch lock/eject hooks (short), while substitutes use push-pull or latch holder mechanisms.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 3428-6202UG with D3428-6002-AR? A: Yes. Both maintain 20 positions, 2 rows, 2.54mm pitch, through-hole solder termination, and 4-wall shrouding. D3428-6002-AR is active and RoHS Compliant. Fastening type differs (push-pull vs. latch lock), and current rating increases from 1A to 1.75A.

Q: What is the difference between N3428-6002RB and D3428-6002-AR? A: Both are 3M 20-position headers with identical pitch and mounting. N3428-6002RB uses ROHS3 Compliant status and copper alloy contacts, while D3428-6002-AR uses RoHS Compliant status and brass contacts. Contact finish thickness on posts differs (200.0µin vs. 39.4µin).

Q: Are HARTING SEK Series parts compatible with the original 3428-6202UG? A: HARTING parts maintain the 20-position, 2-row, 2.54mm pitch configuration with through-hole solder termination and 4-wall shrouding. Contact length specifications vary (0.228" mating vs. 0.240" original). Verify PCB footprint compatibility. HARTING parts support extended temperature range (-55°C ~ 125°C).

Q: What is the impact of changing from tin-lead to tin post plating? A: The original 3428-6202UG uses tin-lead post plating. All active substitutes use tin-only post plating. This change aligns with RoHS compliance requirements. Solder joint reliability remains equivalent under standard assembly processes.

Q: Does packaging type affect electrical performance? A: No. Packaging (tray or bulk) does not affect electrical or mechanical performance. Selection depends on inventory management and assembly line requirements.

Q: Can I use 09185206324 as a substitute? A: 09185206324 is a HARTING SEK Series part with 20 positions and 2.54mm pitch. However, it features reduced insulation height (0.350" vs. 0.680" original) and latch holder fastening. Verify mechanical compatibility with your application before selection.

Q: What is the significance of REACH Unaffected status? A: REACH Unaffected indicates the part is not subject to REACH substance restrictions. This status applies to HARTING SEK Series substitutes and simplifies compliance documentation for European markets.
