Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 3-644767-8 are identified based on strict alignment with the following critical parameters:

Electrical Compatibility Parameters:

• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 8
• Number of Rows: 1
• Contact Type: Male Pin
• Voltage Rating: 600VAC (or equivalent)
• Material Flammability Rating: UL94 V-0

Mechanical Compatibility Parameters:

• Connector Type: Header
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 1 Wall
• Fastening Type: Friction Lock
• Style: Board to Cable/Wire or Board to Board

Environmental & Compliance Parameters:

• Operating Temperature Range: -55°C ~ 105°C (or compatible range)
• RoHS Status: RoHS Compliant or ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The Molex 0026482085 connector meets these substitution criteria through matching pitch, position count, row configuration, contact type, mounting method, termination style, shrouding design, and fastening mechanism. Both parts maintain UL94 V-0 flammability compliance and unlimited moisture sensitivity ratings.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0026482085 connector is a suitable substitute for the obsolete TE Connectivity 3-644767-8 based on the following engineering criteria:

Compliance & Regulatory Status: The Molex part maintains ROHS3 compliance, which supersedes the RoHS compliance of the original part, ensuring continued regulatory alignment. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, supporting consistent export and procurement documentation.

Product Availability: The Molex 0026482085 is classified as Active, providing assured long-term availability and supply chain continuity. The original TE Connectivity part is Obsolete, making the active Molex alternative the appropriate selection for new designs and ongoing production requirements.

Electrical & Mechanical Compatibility: The substitute part matches all critical electrical parameters including pitch, position count, contact type, and voltage rating. Mechanical compatibility is confirmed through identical mounting type, termination method, shrouding configuration, and fastening mechanism. Both parts maintain UL94 V-0 flammability compliance and unlimited moisture sensitivity ratings, supporting equivalent performance in general purpose and industrial applications.

Frequently Asked Questions (FAQ)

Q: What makes the Molex 0026482085 a valid substitute for the TE Connectivity 3-644767-8?

A: The Molex part matches all critical substitution parameters: 8-position, single-row header configuration with 0.156" (3.96mm) pitch, through-hole solder termination, shrouded single-wall design, friction lock fastening, and identical flammability and moisture sensitivity ratings. Both parts support board-to-cable/wire connections with gold-plated mating contacts and tin-plated posts.

Q: Are there any dimensional differences between these connectors?

A: Minor dimensional variations exist. The Molex part features a contact length of 0.450" (11.43mm) compared to 0.400" (10.16mm) on the TE Connectivity part, and an overall contact length of 0.750" (19.05mm) versus 0.700" (17.78mm). The Molex insulation height is 0.500" (12.70mm) compared to 0.425" (10.80mm). These differences do not affect functional compatibility in standard through-hole PCB applications.

Q: What is the difference between the contact shapes?

A: The TE Connectivity 3-644767-8 features circular contacts, while the Molex 0026482085 uses square contacts. Both contact geometries are compatible with standard 0.156" (3.96mm) pitch mating receptacles and provide equivalent electrical performance and mechanical retention through friction lock fastening.

Q: Does the Molex part support breakaway functionality?

A: The Molex 0026482085 is classified as a Header with Breakaway capability, whereas the TE Connectivity part is a standard Header. The breakaway feature on the Molex connector allows individual positions to be separated if required, providing additional design flexibility without compromising compatibility with standard mating receptacles.

Q: Are the insulation materials compatible?

A: The TE Connectivity part uses Thermoplastic, Glass Filled insulation material, while the Molex part uses Polyester. Both materials meet UL94 V-0 flammability requirements and are suitable for general purpose, industrial, and related applications. Material selection does not affect electrical or mechanical compatibility.

Q: What is the inventory status for these parts?

A: The TE Connectivity 3-644767-8 has 882 pieces in stock but is classified as Obsolete. The Molex 0026482085 has 1557 pieces in stock and is classified as Active, ensuring continued availability for new orders and production requirements.

Q: Are both parts RoHS compliant?

A: Yes. The TE Connectivity part is RoHS Compliant, and the Molex part is ROHS3 Compliant. ROHS3 compliance represents an updated regulatory standard that supersedes RoHS compliance, ensuring the Molex part meets current and future regulatory requirements.
