Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0874371133 are qualified based on the following critical parameters that determine functional interchangeability:

Primary Matching Criteria:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (11)
• Pitch spacing (0.059" / 1.50mm)
• Mounting type (Surface Mount)
• Style (Board to Cable/Wire)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact shape (Square)
• Insulation material class (Polyamide/Nylon)
• Flammability rating (UL94 V-0)

The substitute parts identified maintain these core parameters, ensuring mechanical and electrical compatibility with applications designed for the original component. Variations in contact finish, insulation height, and fastening type are noted but do not prevent functional substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

Molex 0874371143 is the primary direct substitute for the obsolete Molex 0874371133. Both components share identical series designation (Pico-SPOX 87437), matching all critical mechanical and electrical parameters. The 0874371143 offers superior availability with 18,641 units in stock and active product status. The component achieves ROHS3 compliance, addressing regulatory requirements that the original part does not meet. Contact finish has transitioned from Tin-Lead to Tin, aligning with modern manufacturing standards. This substitute is recommended for new designs and production continuity where Molex ecosystem compatibility is prioritized.

TE Connectivity 1-292230-1 provides an alternative from a different manufacturer within the Mini CT series. This part maintains core functional parameters but introduces design variations: fastening type changes from Push-Pull to Detent Lock, contact mating length reduces from 0.106" to 0.094", and insulation height increases from 0.199" to 0.272". These differences require PCB layout verification and connector interface compatibility assessment. The component is ROHS3 compliant and offers strong inventory availability (15,653 units). Selection of this substitute is appropriate when multi-source qualification is required or when application mechanical constraints accommodate the dimensional variations.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0874371143 directly replace the obsolete 0874371133 without PCB modifications?

A: Yes. The Molex 0874371143 maintains identical pitch spacing (1.50mm), position count (11), mounting type (surface mount), and contact mating length (0.106" / 2.70mm). No PCB layout changes are required for this substitution.

Q: What is the primary difference between the Molex 0874371143 and TE Connectivity 1-292230-1?

A: The TE Connectivity part uses Detent Lock fastening instead of Push-Pull, has a shorter contact mating length (0.094" vs 0.106"), and greater insulation height (0.272" vs 0.199"). These differences may affect mating force, connector retention, and vertical clearance on the PCB. Mechanical compatibility must be verified for the specific application.

Q: Are all substitute parts RoHS compliant?

A: The Molex 0874371143 and TE Connectivity 1-292230-1 are both ROHS3 compliant. The original Molex 0874371133 is RoHS non-compliant. For applications requiring RoHS compliance, either substitute part is suitable.

Q: What packaging options are available for these parts?

A: The Molex 0874371143 is supplied in Cut Tape (CT) packaging. The TE Connectivity 1-292230-1 is supplied in Tape & Reel (TR) packaging. Packaging selection depends on production volume and assembly line requirements.

Q: Do all parts share the same contact finish?

A: The original Molex 0874371133 uses Tin-Lead contact finish. Both substitute parts use Tin finish. Tin finish is standard in modern connector manufacturing and is compatible with lead-free solder processes.

Q: What is the operating temperature range for these connectors?

A: Operating temperature data is not provided for the Molex parts. The TE Connectivity 1-292230-1 operates from -30°C to 105°C. Consult manufacturer datasheets for complete thermal specifications.

Q: Are moisture sensitivity levels identical across all parts?

A: Yes. All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
