Engineering Selection Recommendations

The 4-794629-2 is the direct active substitute for the obsolete 1-794629-2. Selection of the substitute part is based on the following engineering criteria:

Product Status: The 1-794629-2 is classified as obsolete, making continued procurement from standard channels unavailable. The 4-794629-2 maintains active product status with current manufacturing support and availability.

Electrical and Mechanical Compatibility: All critical electrical parameters (voltage rating, operating temperature range, contact specifications) and mechanical parameters (pitch, position count, mounting configuration, shrouding) are identical between the two parts. This ensures direct functional interchangeability in existing circuit designs and PCB layouts.

Compliance and Certifications: The 4-794629-2 carries RoHS Compliant certification, meeting current regulatory requirements for electronic component procurement. The 1-794629-2 lists RoHS status as not applicable, reflecting its obsolete classification.

Contact Finish Specification: The 4-794629-2 specifies Tin post finish, compared to Tin-Lead in the 1-794629-2. Both finishes are suitable for solder termination and provide equivalent solderability characteristics for this connector application.

Packaging Configuration: The 4-794629-2 is supplied in Tape & Reel (TR) packaging, standard for high-volume manufacturing operations. The 1-794629-2 packaging specification is not provided.

Moisture Sensitivity: The 4-794629-2 carries MSL 2 (1 Year) rating, indicating standard moisture handling requirements for surface mount components. The 1-794629-2 lists MSL 1 (Unlimited), typical of obsolete part documentation.
