Engineering Selection Recommendations

Primary Substitute: TE Connectivity 5-104319-2

The TE Connectivity 5-104319-2 is the direct equivalent substitute for the obsolete 104319-2. Both components share identical electrical and mechanical specifications within the AMPMODU Mod II series. The 5-104319-2 maintains active product status and achieves RoHS compliance, addressing regulatory requirements for new designs. The only material difference is the contact finish post composition (Tin vs. Tin-Lead), which does not affect functional compatibility. This part is recommended as the primary replacement for direct substitution in existing designs.

Secondary Substitutes: Molex 0741640020 and 0741640120

The Molex C-Grid 74164 series connectors (0741640020 and 0741640120) function as compatible alternatives when the primary substitute is unavailable. These parts maintain electrical compatibility through identical pitch, position count, row spacing, and mounting configuration. Both Molex parts are active products with ROHS3 compliance. The 0741640020 features gold mating contact finish, while the 0741640120 features tin mating contact finish. Differences in connector type classification, contact material, insulation material, and fastening mechanism do not preclude functional interchangeability in applications where the core electrical and mechanical parameters are the determining factors. Operating temperature and current rating specifications are not provided for the Molex parts; verification against application requirements is necessary for temperature-critical or high-current applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-104319-2 be used as a direct replacement for the 104319-2?

A: Yes. The 5-104319-2 is a direct equivalent with identical electrical and mechanical specifications. The primary advantage is active product status and RoHS compliance. The contact finish post material differs (Tin vs. Tin-Lead), but this does not affect functional compatibility.

Q: What are the key differences between the TE Connectivity and Molex substitute options?

A: The TE Connectivity 5-104319-2 is classified as a Header connector, while the Molex 0741640020 and 0741640120 are classified as Receptacle connectors. The Molex parts use Copper Alloy contacts and Liquid Crystal Polymer insulation, compared to Phosphor Bronze contacts and Thermoplastic insulation in the TE Connectivity parts. Fastening mechanisms also differ: TE Connectivity uses Detent Lock, while Molex uses Latch Holder. Despite these differences, all parts maintain the same pitch, position count, row spacing, mounting type, and shrouding configuration.

Q: Are the Molex parts suitable for high-temperature applications?

A: The Molex 0741640020 and 0741640120 do not specify operating temperature ranges in the provided data. The TE Connectivity 104319-2 and 5-104319-2 are rated for -65°C ~ 105°C. For applications requiring confirmed temperature specifications, the TE Connectivity 5-104319-2 is the recommended choice.

Q: Do all substitute parts meet the same current rating?

A: The TE Connectivity 104319-2 and 5-104319-2 are rated for 3A. The Molex 0741640020 and 0741640120 do not specify current ratings in the provided data. For applications requiring confirmed current specifications, the TE Connectivity 5-104319-2 is the recommended choice.

Q: What is the difference between the two Molex part numbers?

A: The Molex 0741640020 and 0741640120 differ in contact finish specifications. The 0741640020 features gold mating contact finish with 15.0µin thickness and tin post finish with 74.8µin thickness. The 0741640120 features tin mating contact finish with 150.0µin thickness and tin post finish with 150.0µin thickness. Both parts are otherwise identical in electrical and mechanical configuration.

Q: Are all substitute parts RoHS compliant?

A: The TE Connectivity 104319-2 is RoHS non-compliant. The TE Connectivity 5-104319-2 is RoHS compliant. Both Molex parts (0741640020 and 0741640120) are ROHS3 compliant. For designs requiring RoHS compliance, the 5-104319-2 or Molex alternatives are appropriate selections.

Q: What packaging options are available?

A: The TE Connectivity 5-104319-2, Molex 0741640020, and Molex 0741640120 are all supplied in Tube packaging. Packaging specifications for the original 104319-2 are not provided in the available data.
