Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0874371433 is determined by strict alignment across the following critical parameters: connector type (header), contact type (male pin), number of positions (14), mating pitch (1.50mm), mounting method (surface mount), shrouding configuration (4-wall), termination method (solder), and application style (board to cable/wire). All identified substitutes maintain these core electrical and mechanical specifications.

The primary substitute, Molex 0874371443, is a direct series variant within the Pico-SPOX 87437 family, differing only in packaging format and RoHS compliance status. The secondary substitute, TE Connectivity 1-292230-4, represents a cross-manufacturer alternative from the Mini CT series that maintains functional equivalence across all critical mating and termination parameters while introducing minor dimensional variations in contact length and insulation height.

Parameter Comparison

Engineering Selection Recommendations

For applications currently utilizing the Molex 0874371433, the Molex 0874371443 represents the optimal substitution path. Both components belong to the identical Pico-SPOX 87437 series and maintain complete functional and dimensional equivalence. The primary distinction is product status: the 0874371443 is actively manufactured and ROHS3 compliant, whereas the 0874371433 is obsolete and RoHS non-compliant. The 0874371443 is available in Tape & Reel packaging with significantly higher inventory levels (2501 units in stock versus 849 units), supporting long-term supply chain stability.

The TE Connectivity 1-292230-4 serves as a secondary cross-manufacturer alternative for applications where Molex supply becomes constrained. This connector maintains all critical electrical and mating specifications but introduces dimensional variations: contact length is reduced by 0.012" (0.30mm) and insulation height is increased by 0.073" (1.86mm). These dimensional differences may impact PCB layout compatibility and mating force characteristics. The TE Connectivity part includes a board guide feature and operates across the temperature range of -30°C to 105°C, with a voltage rating of 50VAC. Selection of this alternative requires verification of mechanical fit within the target application's connector cavity and mating interface.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0874371443 be used as a direct replacement for the 0874371433?

A: Yes. Both connectors are members of the Pico-SPOX 87437 series and share identical connector type, contact configuration, pitch, position count, mounting method, shrouding, and termination specifications. The 0874371443 is the active production equivalent and is recommended for new designs and ongoing procurement.

Q: What are the key differences between the Molex 0874371443 and TE Connectivity 1-292230-4?

A: The primary differences are manufacturer, series designation, and physical dimensions. The TE Connectivity connector has a shorter mating contact length (0.094" versus 0.106") and taller insulation height (0.272" versus 0.199"). The TE part includes a board guide feature and specifies operating temperature range and voltage rating. These dimensional variations may affect PCB layout and mating interface compatibility.

Q: Are there packaging differences between the main part and substitutes?

A: Yes. The Molex 0874371433 is supplied in standard packaging, while the Molex 0874371443 is packaged in Tape & Reel format. The TE Connectivity 1-292230-4 is also supplied in Tape & Reel. Tape & Reel packaging is standard for high-volume automated assembly processes.

Q: What is the significance of the RoHS compliance difference?

A: The Molex 0874371433 is RoHS non-compliant, while the 0874371443 is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the 0874371443 is the appropriate selection. Both parts maintain identical electrical and mechanical performance.

Q: Can the TE Connectivity 1-292230-4 be used in existing PCB designs?

A: The TE Connectivity connector maintains the same 1.50mm pitch and 14-position configuration, but dimensional differences in contact length and insulation height may require PCB layout verification. The increased insulation height and board guide feature may affect connector cavity dimensions and mating force. Physical compatibility assessment is necessary before implementation.

Q: What is the fastening type difference between the main part and the TE substitute?

A: The Molex 0874371433 and 0874371443 use push-pull fastening, while the TE Connectivity 1-292230-4 uses detent lock fastening. This difference affects mating and unmating procedures and may impact application requirements for connector retention and release force.
