Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0705630050 is determined by strict alignment of the following electrical and mechanical parameters:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 16
• Number of rows: 1
• Pitch - mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening type: Latch Holder
• Style: Board to Cable/Wire
• Number of positions loaded: All

The substitute part Molex 1719710016 meets all these core criteria. While secondary parameters such as contact material, insulation material, and contact finish thickness differ, these variations remain within acceptable tolerances for equivalent functional performance in the specified applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 1719710016 is the manufacturer-recommended substitute for the obsolete Molex 0705630050. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory alignment for automotive, industrial, medical, and general-purpose applications.

The primary distinction is product status: the 0705630050 is obsolete, while the 1719710016 is active. This transition ensures long-term supply chain viability and continued manufacturing support. The substitute part incorporates Liquid Crystal Polymer (LCP) insulation material in place of thermoplastic glass-filled material, and uses brass contacts instead of phosphor bronze, with reduced contact finish thickness. These material changes maintain functional equivalence while reflecting current manufacturing standards.

Both parts share identical mechanical dimensions, pitch spacing, mounting configuration, and electrical interface characteristics. The 1719710016 includes a polarizing key feature and specified operating temperature range (-40°C ~ 105°C) and current rating (3A at 250V), providing enhanced design clarity for new applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1719710016 directly replace the 0705630050 in existing designs?

A: Yes. Both parts maintain identical connector type, contact type, position count, row configuration, pitch spacing, mounting type, shrouding, termination method, and fastening type. The mechanical and electrical interfaces are equivalent.

Q: What is the significance of the insulation material change from thermoplastic glass-filled to Liquid Crystal Polymer (LCP)?

A: Liquid Crystal Polymer offers superior dimensional stability, chemical resistance, and thermal performance compared to glass-filled thermoplastic. This material upgrade reflects current manufacturing standards while maintaining UL94 V-0 flammability compliance and functional compatibility.

Q: Does the contact material change from phosphor bronze to brass affect performance?

A: Both materials provide adequate electrical conductivity and mechanical durability for this connector class. The brass contacts in the substitute part, combined with tin plating, maintain equivalent contact resistance and mating force characteristics.

Q: Why is the contact finish thickness reduced in the substitute part?

A: The 1719710016 uses 100.0µin (2.54µm) tin plating compared to 150.0µin (3.81µm) in the original part. This reduction reflects optimized plating specifications that maintain corrosion protection and electrical performance while reducing material usage.

Q: Are there packaging differences between these parts?

A: The 0705630050 packaging is not specified in available data. The 1719710016 is supplied in tube packaging. Confirm packaging requirements with your procurement team.

Q: What is the polarizing key feature on the 1719710016?

A: The polarizing key is a mechanical feature that prevents incorrect mating orientation. This enhancement improves assembly reliability in production environments.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts are rated for automotive applications and maintain ROHS3 compliance and EAR99 export classification.
