Engineering Selection Recommendations

All listed substitute parts maintain functional compatibility with the 3M 3433-6402 based on matching critical electrical and mechanical parameters. Selection among substitutes should prioritize the following factors:

Product Status: All substitute parts are classified as Active, ensuring ongoing availability and manufacturing support. The original 3M 3433-6402 is obsolete and should not be specified for new designs.

RoHS Compliance: For applications requiring RoHS3 compliance, select from TE Connectivity 1-5102321-0, TE Connectivity 1-5499206-0, TE Connectivity 1-5746443-0, or Assmann WSW AWH 50G-0202-T. For applications requiring general RoHS compliance, JAE Electronics PS-50PE-D4T2-M1E is acceptable. TE Connectivity 1-499206-0 and Amphenol ICC 53611-G50-6 are RoHS non-compliant.

Operating Temperature Range: TE Connectivity parts (1-499206-0, 1-5102321-0, 1-5499206-0, 1-5746443-0) and Assmann WSW AWH 50G-0202-T provide extended low-temperature operation to -65°C or -40°C respectively, exceeding the original -55°C specification. Amphenol ICC 53611-G50-6 and JAE Electronics PS-50PE-D4T2-M1E do not specify operating temperature ranges.

Voltage Rating: TE Connectivity parts specify 250VAC voltage rating. Original and other substitutes do not specify voltage ratings.

Current Rating: Assmann WSW AWH 50G-0202-T specifies 3A per contact, exceeding the 1A specification of the original part. All other substitutes maintain 1A or equivalent current handling.

Packaging: TE Connectivity 1-5746443-0 and JAE Electronics PS-50PE-D4T2-M1E are supplied in bulk packaging. TE Connectivity 1-499206-0, 1-5102321-0, 1-5499206-0, Amphenol ICC 53611-G50-6, and Assmann WSW AWH 50G-0202-T are supplied in tray packaging.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 3M 3433-6402 with any of the listed substitutes?

A: Yes. All listed substitute parts maintain the critical electrical and mechanical parameters required for functional compatibility: 50-position, 2-row header configuration at 2.54mm pitch with shrouded 4-wall design, through-hole mounting, solder termination, and gold-plated mating contacts. Physical board layout and mating interface compatibility are preserved.

Q: What is the primary reason for finding substitutes for the 3M 3433-6402?

A: The 3M 3433-6402 is classified as obsolete. Substitute parts are necessary to ensure continued design support, procurement availability, and manufacturing continuity for applications currently using this connector.

Q: Are there differences in contact post length among the substitutes?

A: Yes. Contact post lengths vary: 3M original is 0.112" (2.84mm), TE 1-499206-0 and 1-5499206-0 are 0.110" (2.79mm), TE 1-5102321-0 is 0.155" (3.94mm), TE 1-5746443-0 is 0.174" (4.42mm), Amphenol 53611-G50-6 is 0.150" (3.81mm), Assmann AWH 50G-0202-T is 0.130" (3.30mm), and JAE PS-50PE-D4T2-M1E is 0.130" (3.30mm). These variations are within allowable mechanical tolerances for through-hole solder termination and do not affect electrical performance or mating interface compatibility.

Q: Which substitute offers the best RoHS compliance?

A: TE Connectivity 1-5102321-0, 1-5499206-0, 1-5746443-0, and Assmann WSW AWH 50G-0202-T are ROHS3 compliant. JAE Electronics PS-50PE-D4T2-M1E is RoHS compliant. TE Connectivity 1-499206-0 and Amphenol ICC 53611-G50-6 are RoHS non-compliant.

Q: What is the difference between TE Connectivity 1-499206-0 and 1-5499206-0?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary difference is RoHS compliance status: 1-499206-0 is RoHS non-compliant, while 1-5499206-0 is ROHS3 compliant. Both feature tin-plated posts and operate across -65°C to 105°C with 250VAC voltage rating.

Q: Does packaging type affect electrical performance?

A: No. Packaging type (bulk or tray) does not affect electrical or mechanical performance. Selection should be based on procurement quantity requirements and inventory management practices.

Q: Can I use Assmann WSW AWH 50G-0202-T as a direct substitute despite its 3A current rating?

A: Yes. The Assmann part is electrically and mechanically compatible. The 3A current rating exceeds the original 1A specification, making it suitable for applications requiring the original 1A rating. The higher current rating does not create compatibility issues in circuits designed for 1A operation.

Q: Are there any differences in insulation material between the original and substitutes?

A: The 3M 3433-6402 uses polybutylene terephthalate (PBT) with polyester and glass filler. TE Connectivity parts do not specify insulation material in the provided data. Amphenol ICC 53611-G50-6 uses thermoplastic insulation. Assmann WSW AWH 50G-0202-T uses PBT with glass filler. JAE Electronics PS-50PE-D4T2-M1E uses PBT. All materials meet UL94 V-0 flammability requirements.

Q: Which substitute has the widest operating temperature range?

A: TE Connectivity 1-499206-0, 1-5102321-0, 1-5499206-0, and 1-5746443-0 all operate from -65°C to 105°C, providing 10°C lower minimum temperature than the original -55°C specification. Assmann WSW AWH 50G-0202-T operates from -40°C to 105°C. Amphenol ICC 53611-G50-6 and JAE Electronics PS-50PE-D4T2-M1E do not specify operating temperature ranges.
