Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 4-644991-0 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 10
• Number of Rows: 1
• Shrouding: Shrouded - 1 Wall
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Friction Lock
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0

The identified substitute parts, Molex 0026604100 and Molex 0417910840, satisfy all mandatory matching parameters. Both are active products with RoHS3 compliance and MSL 1 rating. Variations in contact finish specifications, insulation material composition, and contact post length do not preclude substitution when mechanical and electrical interface requirements are met.

Engineering Selection Recommendations

TE Connectivity 4-644991-0 (Primary Part)

Selection of the primary part is appropriate when TE Connectivity supply chain continuity is established and inventory availability meets project timelines. This part maintains active product status with RoHS compliance and unlimited moisture sensitivity rating, suitable for deployment in general purpose and industrial applications.

Molex 0026604100 (Substitute - Tin Finish)

The Molex 0026604100 serves as a direct functional substitute with tin contact finish matching the primary part specification. This part is active, ROHS3 compliant, and carries MSL 1 rating. Higher inventory availability (12,663 units) supports rapid procurement. Selection is appropriate when tin-finished mating contacts are required and Molex supply chain integration is feasible.

Molex 0417910840 (Substitute - Gold Finish)

The Molex 0417910840 provides substitution capability with gold-plated mating contacts, offering enhanced corrosion resistance compared to tin finish. This part is active, ROHS3 compliant, and carries MSL 1 rating. Selection is appropriate for applications requiring superior contact durability or when gold finish specifications are mandated by system design requirements.

All three parts satisfy UL94 V-0 flammability requirements and EAR99 export classification. Selection between substitute parts depends on contact finish specification alignment with application requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can Molex 0026604100 and Molex 0417910840 be used interchangeably with TE Connectivity 4-644991-0?

A: Both Molex parts satisfy the critical mechanical and electrical interface parameters required for substitution. The primary difference is contact finish: Molex 0026604100 features tin finish matching the TE part, while Molex 0417910840 features gold finish. Interchangeability depends on application contact finish requirements. Both parts maintain identical pitch, position count, shrouding, mounting type, and termination method.

Q: What are the key differences between the substitute parts?

A: The primary distinction between Molex 0026604100 and Molex 0417910840 is the mating contact finish. Molex 0026604100 provides tin finish with 60.0µin thickness, while Molex 0417910840 provides gold finish with 15.0µin thickness. Both parts share identical connector geometry, pitch spacing, and mounting characteristics. Contact finish selection depends on application corrosion resistance requirements and system design specifications.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: Contact length at mating interface is identical across all three parts at 0.450" (11.43mm). Minor variations exist in post length and overall contact length between the TE part and Molex substitutes, but these do not affect board-level mounting compatibility or mating interface performance. Insulation height differs slightly (TE: 0.545", Molex: 0.446"), which does not impact through-hole mounting or connector engagement.

Q: Do all parts meet the same compliance and regulatory standards?

A: All three parts carry UL94 V-0 flammability rating and EAR99 export classification. TE Connectivity 4-644991-0 is RoHS Compliant, while both Molex substitutes are ROHS3 Compliant. All parts carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance alignment supports direct substitution in regulated applications.

Q: What inventory considerations apply to part selection?

A: TE Connectivity 4-644991-0 maintains 967 units in stock. Molex 0026604100 provides significantly higher availability at 12,663 units, supporting rapid procurement. Molex 0417910840 maintains 2,371 units in stock. Inventory levels may influence part selection when project timelines require expedited delivery.

Q: Can the contact finish difference affect electrical performance?

A: Contact finish does not alter electrical interface performance at the mating surface. Tin and gold finishes both provide adequate conductivity for the specified 600VAC voltage rating. Contact finish selection is driven by corrosion resistance requirements and application environment rather than electrical performance considerations.
