Engineering Selection Recommendations

Exact Pitch Match (5.00mm) - Preferred Substitutes:

The Molex 0395211003 and 0395216003 provide direct dimensional compatibility with the TE Connectivity 796643-3. Both parts maintain identical pitch, position count, voltage rating, and current rating. The primary difference is housing color (black versus green). Both are ROHS3 compliant and active products. The Molex 0395211003 is recommended as the primary substitute due to matching electrical specifications and active product status.

The Phoenix Contact 1924208 and On Shore Technology OSTOQ037150 also match the 5.00mm pitch specification. The Phoenix Contact 1924208 provides a higher current rating (16 A) and maintains the 300 V UL voltage specification. The On Shore Technology OSTOQ037150 operates across a narrower temperature range (-30°C to 105°C) compared to the original part (-40°C to 110°C).

Near-Pitch Match (5.08mm) - Secondary Substitutes:

The Molex 0395311003, Phoenix Contact 1755749 and 1924318, and On Shore Technology EDSTLZ955/3 and OSTOQ035450 feature a 5.08mm pitch, representing a 0.08mm dimensional variation from the original specification. These parts maintain the 300 V UL voltage rating and 3-position configuration. Board layout verification is required to confirm mechanical fit within the 5.08mm pitch constraint. The Molex 0395311003 is recommended among 5.08mm alternatives due to matching current rating (15 A) and ROHS3 compliance.

Compliance and Certification:

All substitute parts maintain UL94 V-0 flammability rating or equivalent compliance. All listed substitutes are ROHS3 compliant or RoHS compliant, meeting environmental regulatory requirements. All parts are classified as active products, ensuring continued availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395211003 be used as a direct replacement for the TE Connectivity 796643-3?

A: Yes. The Molex 0395211003 matches the critical electrical and mechanical parameters: 3 positions, 5.00mm pitch, 15 A current rating, 300 V voltage rating, vertical through-hole mounting, and solder termination. Both parts feature tin contact mating finish and UL94 V-0 flammability rating. The only difference is housing color (black for both), making this a direct functional equivalent.

Q: What is the difference between 5.00mm and 5.08mm pitch substitutes?

A: The pitch dimension determines the center-to-center spacing between connector positions. A 5.00mm pitch part cannot be mechanically interchanged with a 5.08mm pitch part on the same printed circuit board without layout modification. The 0.08mm difference accumulates across multiple positions, resulting in incompatible mounting hole patterns. Substitution between these pitch values requires board redesign verification.

Q: Are Phoenix Contact parts suitable substitutes for the TE Connectivity 796643-3?

A: Phoenix Contact 1924208 is suitable for applications where the 5.00mm pitch requirement is maintained. This part provides a higher current rating (16 A) and maintains the 300 V UL voltage specification. Phoenix Contact 1755749 and 1924318 feature 5.08mm pitch and require board layout verification. All Phoenix Contact alternatives are ROHS3 compliant and active products.

Q: What is the operating temperature range consideration for substitution?

A: The TE Connectivity 796643-3 operates from -40°C to 110°C. The Molex substitutes operate from -40°C to 105°C, providing a 5°C reduction in maximum operating temperature. The On Shore Technology parts operate from -30°C to 105°C, providing a 10°C reduction in minimum operating temperature and 5°C reduction in maximum operating temperature. Application requirements must confirm compatibility with these temperature ranges.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. All listed substitute parts are either RoHS Compliant or ROHS3 Compliant. The TE Connectivity 796643-3 is RoHS Compliant. All Molex, Phoenix Contact, and On Shore Technology alternatives meet or exceed these environmental compliance standards.

Q: What is the significance of the contact material difference between Copper Alloy and Brass?

A: The TE Connectivity 796643-3 specifies Copper Alloy contact material. The Molex substitutes specify Brass contact material. Both materials provide adequate electrical conductivity and tin plating compatibility for solder termination applications. The contact material difference does not affect functional interchangeability within the specified electrical parameters.

Q: Can On Shore Technology OSTOQ parts be used as substitutes?

A: The On Shore Technology OSTOQ037150 matches the 5.00mm pitch and maintains 300 V UL voltage rating. The OSTOQ035450 features 5.08mm pitch. Both parts are ROHS3 compliant and active products. However, current rating specifications are not provided for these parts, requiring verification against application requirements before substitution.

Q: What mounting type differences exist among the substitute parts?

A: The TE Connectivity 796643-3 specifies through-hole mounting with solder termination. All listed Molex and Phoenix Contact substitutes maintain through-hole mounting with solder termination. The On Shore Technology parts specify solder mounting type. All alternatives are compatible with standard PCB solder assembly processes.
