Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5-146252-3

The TE Connectivity 5-146252-3 is the manufacturer-recommended equivalent for the obsolete 104433-3. This part maintains identical electrical and mechanical specifications within the AMPMODU Mod II series while offering active product status. The 5-146252-3 provides ROHS3 compliance, addressing regulatory requirements that the original part does not meet. The transition from Thermoplastic to Liquid Crystal Polymer (LCP) insulation material provides improved thermal and mechanical performance characteristics. This part is the preferred choice for direct replacement in new designs and legacy system updates.

Secondary Recommendations: Molex C-Grid 70280 and 70287 Series

Molex C-Grid series connectors (0010897063, 0010977065, 0010977066, 0702800711, 0702800751, 0702800791, 0702871050, 0702871148, 0702871246) provide functionally equivalent alternatives from a different manufacturer. All Molex options maintain the critical mating parameters: 0.100" (2.54mm) pitch, 6 positions in 2 rows, square contact shape, and push-pull fastening. All Molex alternatives are ROHS3 compliant and feature Liquid Crystal Polymer (LCP) insulation with glass filling, offering enhanced mechanical and thermal properties compared to the original thermoplastic design.

Contact Finish Considerations:

Selection among Molex alternatives depends on contact finish requirements:

Gold-plated mating contacts: 0010897063, 0010977066, 0702800751, 0702800791, 0702871148, 0702871246
Tin-plated mating contacts: 0010977065, 0702800711, 0702871050

Post Length Variations:

Molex C-Grid 70280 series parts (0702800711, 0702800751, 0702800791) feature extended post length of 0.185" (4.70mm) compared to the standard 0.125" (3.18mm) found in the original part and other alternatives. This variation affects overall connector height and board-to-board spacing requirements.

Termination Type Variations:

Molex C-Grid 70287 series (0702871050, 0702871148, 0702871246) incorporate kinked pin termination in addition to solder capability, providing enhanced mechanical retention during assembly compared to standard solder-only termination.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-146252-3 be used as a direct replacement for the 104433-3 in existing designs?

A: Yes. The 5-146252-3 maintains identical pitch (0.100" / 2.54mm), position count (6 in 2 rows), contact type (male pin), mounting method (through hole), and fastening mechanism (push-pull). The primary differences are product status (active versus obsolete), RoHS compliance (ROHS3 versus non-compliant), and insulation material (LCP versus thermoplastic). These differences represent improvements suitable for direct substitution.

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

A: Both manufacturers provide connectors meeting the critical mating parameters. TE Connectivity 5-146252-3 maintains the AMPMODU Mod II series designation. Molex alternatives use C-Grid 70280 or C-Grid 70287 series designations. All options feature square contacts, push-pull fastening, and UL94 V-0 flammability rating. Molex parts universally employ Liquid Crystal Polymer (LCP) with glass filling for insulation, while the TE option uses standard LCP. Contact finish and post length vary across Molex options.

Q: How do contact finish specifications affect part selection?

A: Contact finish determines mating surface characteristics and corrosion resistance. Gold-plated mating contacts provide superior corrosion resistance and are suitable for low-current signal applications. Tin-plated mating contacts are appropriate for general-purpose applications with adequate current capacity. The original 104433-3 specifies gold mating contacts with tin-lead post finish. The TE 5-146252-3 maintains gold mating contacts with tin post finish. Molex alternatives offer both gold and tin mating contact options.

Q: What is the significance of post length variations in Molex C-Grid 70280 parts?

A: Molex C-Grid 70280 series parts (0702800711, 0702800751, 0702800791) feature 0.185" (4.70mm) post length compared to the standard 0.125" (3.18mm) in the original part and other alternatives. This extended post length increases overall connector height from 0.533" (13.55mm) to 0.595" (15.11mm). This variation affects board-to-board spacing and must be evaluated against specific application requirements. Standard post length alternatives are available if spacing constraints exist.

Q: Are Molex C-Grid 70287 series parts with kinked pin termination compatible with standard PCB layouts?

A: Molex C-Grid 70287 series parts (0702871050, 0702871148, 0702871246) incorporate kinked pin termination, which provides enhanced mechanical retention during assembly. The kinked pin design does not affect electrical compatibility or mating characteristics. PCB footprints designed for standard press-fit or solder termination accommodate kinked pin variants. The kinked pin feature provides additional mechanical stability during manufacturing and field service.

Q: What compliance certifications apply to substitute parts?

A: The original 104433-3 is RoHS non-compliant and REACH affected. The TE Connectivity 5-146252-3 is ROHS3 compliant and REACH unaffected. All Molex alternatives (0010897063, 0010977065, 0010977066, 0702800711, 0702800751, 0702800791, 0702871050, 0702871148, 0702871246) are ROHS3 compliant and REACH unaffected. For applications subject to RoHS or REACH regulations, the TE 5-146252-3 or any Molex alternative satisfies compliance requirements.

Q: How do insulation material differences affect connector performance?

A: The original 104433-3 uses Thermoplastic insulation. The TE 5-146252-3 uses Liquid Crystal Polymer (LCP). Molex alternatives use Liquid Crystal Polymer (LCP) with glass filling. LCP materials provide superior thermal stability, mechanical strength, and dimensional consistency compared to standard thermoplastic. Glass-filled LCP offers enhanced rigidity and thermal performance. These material improvements do not affect electrical compatibility but provide enhanced reliability in demanding thermal or mechanical environments.

Q: Can parts with different contact finishes be intermated?

A: Gold-plated and tin-plated contacts can be intermated without electrical incompatibility. However, contact finish selection should align with application requirements. Gold finishes provide superior corrosion resistance for low-current signal applications. Tin finishes are suitable for general-purpose applications. Mixing contact finishes across a connector assembly is not recommended; maintain consistency within a single mating pair.

Q: What inventory considerations apply to substitute part selection?

A: The TE Connectivity 5-146252-3 maintains the highest inventory availability (5270 pcs) among all alternatives. Molex C-Grid 70287 series part 0702871246 provides substantial inventory (884 pcs). Molex C-Grid 70280 series part 0702800791 offers significant availability (1031 pcs). Inventory levels support both immediate procurement and long-term supply chain planning. Verify current inventory status with component suppliers for time-sensitive applications.
