Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 644486-7 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 7
• Voltage Rating: 250VAC
• Operating Temperature Range: -55°C ~ 105°C

Mechanical Compatibility Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Contact Shape: Square
• Overall Contact Length: 0.440" (11.18mm)
• Insulation Height: 0.410" (10.41mm)

Material & Safety Parameters:

• Contact Material: Copper Alloy
• Insulation Material: Polyester
• Material Flammability Rating: UL94 V-0
• Insulation Color: Black

The substitute part 2-644486-7 maintains full equivalence across all specified electrical and mechanical parameters. Differences in product status, RoHS compliance, and contact finish material (Tin versus Tin-Lead) do not affect functional interchangeability in applications where the original part specifications are required.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 2-644486-7 is functionally equivalent to the obsolete 644486-7 across all specified electrical and mechanical parameters. Selection between these parts is determined by compliance and product availability requirements:

For New Designs and Procurement: The 2-644486-7 is the appropriate selection. This part maintains active product status, ensuring long-term availability and supply chain continuity. The part is ROHS3 compliant and carries REACH Unaffected status, meeting current regulatory requirements for electronic components in most jurisdictions.

Contact Finish Consideration: The primary material difference between the parts is the contact finish. The original 644486-7 uses Tin-Lead plating, while the substitute 2-644486-7 uses Tin plating. Both finishes are applied to Copper Alloy contacts and maintain equivalent electrical performance and reliability characteristics within the specified operating temperature range of -55°C to 105°C and voltage rating of 250VAC.

Compliance Status: The 644486-7 carries RoHS non-compliant status with vendor-undefined REACH status. The 2-644486-7 is ROHS3 compliant and REACH unaffected, making it suitable for applications subject to environmental and regulatory compliance mandates.

Inventory and Availability: The 2-644486-7 maintains higher inventory levels (2251 pieces) compared to the obsolete 644486-7 (1008 pieces), supporting consistent procurement and production scheduling.

Frequently Asked Questions (FAQ)

Q: Are the 644486-7 and 2-644486-7 directly interchangeable?

A: Yes. Both parts are functionally equivalent across all specified electrical and mechanical parameters. They share identical pitch (0.100"/2.54mm), position count (7), voltage rating (250VAC), operating temperature range (-55°C to 105°C), mounting type (through-hole), shrouding configuration (4-wall), and contact geometry. Direct substitution is supported without circuit or mechanical redesign.

Q: What is the difference between Tin-Lead and Tin contact finishes?

A: The 644486-7 features Tin-Lead contact plating, while the 2-644486-7 uses Tin plating. Both finishes provide equivalent electrical conductivity and corrosion resistance within the specified operating parameters. Tin plating is the modern standard and aligns with RoHS compliance requirements. The contact finish does not affect mating performance or electrical characteristics in general-purpose applications.

Q: Why is the 644486-7 listed as obsolete?

A: The 644486-7 is classified as obsolete due to its RoHS non-compliant status and the availability of the functionally equivalent 2-644486-7, which meets current regulatory standards. Obsolete designation indicates that the manufacturer no longer actively produces or supports this part number, though existing inventory may remain available.

Q: What does ROHS3 compliance mean for the 2-644486-7?

A: ROHS3 compliance indicates that the 2-644486-7 meets the Restriction of Hazardous Substances Directive 3 requirements, limiting the use of specific hazardous materials including lead, mercury, cadmium, and certain flame retardants. This certification is required for components used in electronic equipment sold in the European Union and many other jurisdictions.

Q: Are there packaging differences between these parts?

A: The 644486-7 packaging is not specified in the provided data. The 2-644486-7 is supplied in bulk packaging. For specific packaging requirements or tape-and-reel availability, contact the manufacturer directly.

Q: Can the 2-644486-7 be used in applications originally designed for the 644486-7?

A: Yes. The 2-644486-7 maintains full electrical and mechanical compatibility with the 644486-7. Applications requiring the MTA-100 series 7-position header with 2.54mm pitch, through-hole mounting, and 250VAC rating can use the 2-644486-7 as a direct replacement.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture control requirements. These connectors do not require special storage conditions or baking procedures prior to assembly.

Q: Are both parts suitable for general-purpose applications?

A: Yes. Both the 644486-7 and 2-644486-7 are rated for general-purpose applications. The 7-position, 2.54mm pitch configuration supports standard interconnect requirements in industrial, consumer, and commercial electronic equipment.
