Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 4-644627-1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 11
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Friction Lock
• Shrouding: Shrouded - 1 Wall
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

The Molex 0026482115 connector satisfies all mandatory matching parameters, establishing it as a valid substitute. Both connectors maintain identical mating pitch, position count, row configuration, and contact specifications. Both feature through-hole solder termination with friction lock fastening and shrouded single-wall construction. Both achieve UL94 V-0 flammability compliance and MSL 1 moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0026482115 connector is an active product suitable for substitution with the TE Connectivity 4-644627-1 based on the following engineering criteria:

Compliance and Certification Alignment: Both connectors achieve UL94 V-0 material flammability compliance and maintain MSL 1 moisture sensitivity rating, confirming suitability for equivalent applications. The Molex part carries ROHS3 compliance, which supersedes the RoHS compliance of the TE Connectivity part, ensuring regulatory compatibility in current manufacturing environments. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Electrical and Mechanical Compatibility: The connectors match on all critical functional parameters: 0.156" (3.96mm) pitch, 11-position single-row configuration, male pin contact type, through-hole solder termination, and friction lock fastening. Both feature gold-plated mating contacts and tin-plated posts with square contact geometry and shrouded single-wall construction.

Dimensional Considerations: Variations exist in contact post length (0.125" versus 0.172"), overall contact length (0.700" versus 0.750"), and insulation height (0.545" versus 0.500"). These dimensional differences require verification against specific printed circuit board design specifications to ensure proper seating depth and clearance compatibility.

Material Composition Differences: The TE Connectivity part uses copper alloy contacts with thermoplastic glass-filled insulation, while the Molex part uses brass contacts with polyester insulation. Both material sets are established connector standards. The contact finish thickness on mating surfaces differs (30.0µin versus 20.0µin), with the TE Connectivity part providing greater gold plating thickness.

Product Status: Both connectors maintain active product status with current inventory availability, supporting immediate procurement and deployment.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0026482115 directly replace the TE Connectivity 4-644627-1 in existing designs?

A: Direct replacement requires verification of printed circuit board design specifications. While both connectors share identical mating pitch (0.156"), position count (11), and contact configuration, dimensional variations in contact post length and insulation height may affect seating depth and clearance. PCB hole depth and component spacing must be confirmed against both connector specifications before substitution.

Q: What are the key electrical compatibility factors between these connectors?

A: Both connectors feature identical contact type (male pin), contact finish (gold mating, tin post), and contact shape (square). The TE Connectivity part specifies 600VAC voltage rating; the Molex part does not provide voltage specification in available data. Operating temperature range is specified for the TE Connectivity part (-55°C to 105°C) but not provided for the Molex part. Applications requiring specific voltage or temperature performance should reference complete manufacturer datasheets.

Q: How do the insulation materials differ between these parts?

A: The TE Connectivity 4-644627-1 uses thermoplastic with glass filler, while the Molex 0026482115 uses polyester. Both materials achieve UL94 V-0 flammability compliance. Material selection may impact mechanical properties, chemical resistance, and thermal performance in specific application environments. Application requirements should guide material selection.

Q: Are there compliance differences between these connectors?

A: Both connectors achieve UL94 V-0 flammability compliance and MSL 1 moisture sensitivity rating. The TE Connectivity part carries RoHS compliance; the Molex part carries ROHS3 compliance. ROHS3 represents current regulatory requirements and supersedes earlier RoHS standards. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming equivalent export and tariff treatment.

Q: What inventory considerations apply to these substitute parts?

A: The TE Connectivity 4-644627-1 has 952 pieces in stock; the Molex 0026482115 has 1266 pieces in stock. The Molex part is packaged in bulk format, while packaging information for the TE Connectivity part is not specified. Procurement decisions should account for available inventory levels and packaging requirements for production planning.

Q: How do contact finish specifications compare?

A: Both connectors feature gold-plated mating contacts and tin-plated posts. The TE Connectivity part specifies 30.0µin (0.76µm) gold thickness on mating contacts; the Molex part specifies 20.0µin (0.51µm). The TE Connectivity part provides greater gold plating thickness, which may offer enhanced corrosion resistance in demanding environments. The Molex part specifies 100.0µin (2.54µm) tin thickness on posts, while the TE Connectivity specification is not provided.

Q: What contact material differences exist?

A: The TE Connectivity 4-644627-1 uses copper alloy contacts; the Molex 0026482115 uses brass contacts. Both materials are standard connector contact materials with established electrical and mechanical properties. Copper alloy and brass exhibit different mechanical characteristics and corrosion resistance profiles. Application-specific requirements for contact hardness, wear resistance, or corrosion performance should guide material selection.
