Molex 0050290058 Equivalent & Substitute Parts

Part Overview

The Molex 0050290058 is an active rectangular connector header designed for through-hole mounting applications. This 10-position, single-row connector operates at 0.100" (2.54mm) pitch and features shrouded design with friction lock fastening. The component is manufactured with brass contacts finished in tin and polyamide nylon insulation rated UL94 V-0. Substitute parts are identified to address application requirements where alternative mounting technologies, contact finishes, or form factors may be necessary while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0050290058 is determined by the following core parameters:

• Pitch - Mating: 0.100" (2.54mm) — substitute must match exactly
• Number of Positions: 10 — substitute must match exactly
• Connector Type: Header — substitute must match exactly
• Contact Type: Male Pin — substitute must match exactly
• Shrouding: Shrouded - 1 Wall — substitute must match exactly
• Material Flammability Rating: UL94 V-0 — substitute must meet or exceed
• RoHS Status: ROHS3 Compliant — substitute must maintain compliance

The identified substitute part TE Connectivity AMP Connectors 4-647108-0 satisfies these core parameters. The primary difference is the mounting technology: the substitute uses surface mount termination instead of through-hole, making it suitable for applications where PCB layout or assembly process requirements necessitate SMD mounting while maintaining electrical and mechanical interface compatibility at the mating surface.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0050290058 and TE Connectivity 4-647108-0 maintain active product status and ROHS3 compliance. Selection between these parts is determined by PCB assembly methodology and mounting requirements rather than electrical performance.

The Molex 0050290058 is specified for through-hole mounting applications where post-insertion into plated holes and mechanical retention through friction lock is required. This configuration is standard for legacy designs, prototyping, and applications requiring high mechanical robustness.

The TE Connectivity 4-647108-0 is specified for surface mount applications where reflow soldering and automated pick-and-place assembly are employed. This configuration supports modern manufacturing processes and higher-density PCB layouts.

Both parts satisfy UL94 V-0 flammability requirements and maintain unlimited moisture sensitivity level (MSL 1) classification, indicating no special storage or handling precautions are necessary.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-647108-0 be used as a direct replacement for the Molex 0050290058?

A: Direct replacement is not possible without PCB redesign. The Molex part uses through-hole mounting with post termination, while the TE Connectivity part uses surface mount termination. The mating interface (10 positions at 0.100" pitch) is identical, but the board-side attachment method differs fundamentally.

Q: What are the key compatibility criteria for substitution?

A: Mating pitch (0.100"), position count (10), connector type (header), contact type (male pin), and shrouding configuration (shrouded - 1 wall) must remain constant. Mounting technology and contact finish may vary based on application requirements.

Q: Are there electrical performance differences between these parts?

A: Both parts are specified with identical mating pitch and position configuration. The TE Connectivity part specifies operating temperature range (-55°C to 105°C) and voltage rating (250VAC), while the Molex part does not provide these specifications in the available data. Contact finish differs (tin versus gold), which may affect contact resistance characteristics in specific environments.

Q: What is the significance of the contact finish difference?

A: The Molex part features tin finish (60.0µin thickness), while the TE Connectivity part features gold finish (15.0µin thickness). Gold provides superior corrosion resistance and lower contact resistance, particularly in high-reliability or harsh environment applications. Tin is suitable for general-purpose applications with standard environmental protection.

Q: Are both parts suitable for automotive, medical, and telecommunications applications?

A: The Molex 0050290058 is specified for automotive, general purpose, medical, and telecommunications applications. The TE Connectivity 4-647108-0 is specified for general purpose applications. Application suitability should be verified against specific end-use requirements and industry standards applicable to the target market.
