Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 3-644898-8 are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria include:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (8)
• Number of rows (1)
• Pitch spacing (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Style (Board to Cable/Wire)
• Contact finish materials (Gold mating surface, Tin post)
• Insulation material class (Polyester-based)
• Flammability rating (UL94 V-0)

The Molex 0901362208 connector satisfies all critical electrical and mechanical parameters required for functional equivalence. Both connectors maintain identical pitch spacing, position count, mounting orientation, and shrouding configuration. Contact finish specifications and insulation material properties remain compatible within the defined operating envelope.

Engineering Selection Recommendations

TE Connectivity 3-644898-8 (Obsolete)

The original TE Connectivity part is classified as obsolete and carries RoHS Compliant certification. While 1068 units remain in inventory, this part number is no longer in active production. Selection of this part is limited to legacy system maintenance or existing stock utilization.

Molex 0901362208 (Active - Recommended)

The Molex 0901362208 is the functionally equivalent substitute with active product status. This connector is manufactured under the C-Grid III 90136 series and carries ROHS3 Compliant certification, representing current regulatory compliance standards. With 3034 units in inventory and active production status, this part provides long-term design support and supply chain continuity. The Molex connector maintains all critical electrical and mechanical parameters required for direct functional substitution.

Both connectors satisfy UL94 V-0 flammability requirements, unlimited moisture sensitivity classification, and identical export control designations. The Molex part's glass-filled polyester insulation provides enhanced mechanical properties compared to standard polyester, supporting improved durability in demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0901362208 directly replace the TE Connectivity 3-644898-8 in existing designs?

A: Yes. Both connectors share identical pitch spacing (0.100" / 2.54mm), position count (8), mounting configuration (through-hole right-angle), and shrouding design (4-wall). Contact finish specifications and termination methods are equivalent. Physical board layout and mating interface compatibility are maintained.

Q: What are the dimensional differences between these connectors?

A: Contact length specifications differ slightly. The TE Connectivity part features 0.280" (7.11mm) mating contact length and 0.313" (7.95mm) insulation height. The Molex part specifies 0.266" (6.75mm) mating contact length and 0.284" (7.21mm) insulation height. These variations remain within acceptable tolerance ranges for standard board-to-cable applications and do not affect functional compatibility.

Q: Are there compliance differences between the two parts?

A: The TE Connectivity part carries RoHS Compliant certification. The Molex part carries ROHS3 Compliant certification, representing updated regulatory standards. Both parts maintain UL94 V-0 flammability ratings and unlimited moisture sensitivity classification. Both are classified under identical ECCN (EAR99) and HTSUS (8536.69.4040) codes.

Q: What is the difference between the contact finish thicknesses?

A: The TE Connectivity part specifies 30.0µin (0.76µm) gold plating on mating contacts. The Molex part specifies 15.0µin (0.38µm) gold plating on mating contacts. Both thicknesses provide adequate corrosion resistance and electrical conductivity for general-purpose and lighting applications. The Molex part includes 118.1µin (3.00µm) tin plating on post contacts, compared to unspecified post plating thickness on the TE Connectivity part.

Q: What is the fastening difference between these connectors?

A: The TE Connectivity part uses friction lock fastening. The Molex part uses latch holder fastening. Both methods provide secure mating without additional hardware. Latch holder design offers positive engagement confirmation and is standard in the C-Grid III series.

Q: Are these connectors suitable for automotive applications?

A: The TE Connectivity part is specified for general-purpose and lighting applications. The Molex part is specified for automotive and general-purpose applications. Both maintain operating temperature ranges suitable for automotive environments (-55°C ~ 105°C for TE Connectivity; operating temperature not specified for Molex but insulation material properties support equivalent thermal performance).

Q: What is the contact material composition?

A: The TE Connectivity part uses copper alloy contacts. The Molex part uses brass contacts. Both materials provide equivalent electrical conductivity and corrosion resistance for the specified voltage rating (250VAC) and general-purpose applications.

Q: How do the insulation materials differ?

A: The TE Connectivity part uses standard polyester insulation. The Molex part uses polyester with glass reinforcement. Glass-filled polyester provides enhanced mechanical strength and dimensional stability while maintaining equivalent electrical properties and UL94 V-0 flammability rating.
