Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 644486-5 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (5)
• Pitch specification (0.100" / 2.54mm)
• Voltage rating (250VAC)
• Operating temperature range (-55°C ~ 105°C)

Mechanical Compatibility Parameters:

• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Friction Lock)
• Contact shape (Square)
• Insulation material (Polyester)
• Material flammability rating (UL94 V-0)

Physical Dimensions:

• Contact length - mating (0.200" / 5.08mm)
• Contact length - post (0.140" / 3.56mm)
• Overall contact length (0.440" / 11.18mm)
• Insulation height (0.410" / 10.41mm)

The substitute part 2-644486-5 maintains full equivalence across all critical parameters while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 2-644486-5 is the direct functional equivalent of the obsolete 644486-5 model. Both connectors share identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, pitch, voltage rating, operating temperature range, and physical dimensions.

The primary distinction between these parts is product status and regulatory compliance. The 644486-5 is classified as obsolete with RoHS non-compliant status and undefined REACH compliance. The 2-644486-5 maintains active product status with ROHS3 compliance certification and defined REACH unaffected status, providing improved regulatory alignment for current manufacturing standards.

The contact finish specification differs between the two parts: the original 644486-5 uses Tin-Lead plating, while the 2-644486-5 uses Tin plating. This change reflects industry transition toward lead-free manufacturing practices. Tin plating provides equivalent electrical and mechanical performance for general-purpose connector applications while eliminating lead content.

For applications requiring the TE Connectivity MTA-100 series 5-position 0.100" pitch header connector, the 2-644486-5 is the appropriate selection for new designs and production applications. The substitute part maintains full compatibility with existing mating connectors and PCB layouts designed for the original 644486-5 specification.

Frequently Asked Questions (FAQ)

Q: Can the 2-644486-5 be used as a direct replacement for the 644486-5 in existing designs?

A: Yes. The 2-644486-5 is electrically and mechanically equivalent to the 644486-5 across all functional parameters. Both connectors feature identical pitch (0.100" / 2.54mm), position count (5), mounting type (through-hole), shrouding configuration (4-wall), and operating specifications. The connector will mate with existing cable assemblies and PCB layouts designed for the original part.

Q: What is the difference in contact finish between these two parts?

A: The 644486-5 uses Tin-Lead plating on both mating and post contacts. The 2-644486-5 uses Tin plating without lead content. Tin plating provides equivalent electrical conductivity and mechanical durability for general-purpose applications while conforming to lead-free manufacturing standards. Both finishes are compatible with standard soldering processes.

Q: Why is the 644486-5 listed as obsolete?

A: The 644486-5 has been superseded by the 2-644486-5, which offers improved regulatory compliance including ROHS3 certification and defined REACH status. Manufacturers transition connector products to lead-free specifications and updated compliance certifications, resulting in obsolescence of earlier versions.

Q: Are there any packaging differences between these parts?

A: The 644486-5 packaging specification is not defined in the available data. The 2-644486-5 is supplied in bulk packaging. For specific packaging requirements, consult the manufacturer's current product documentation.

Q: What is the current availability of the 644486-5?

A: The 644486-5 is listed as obsolete. Current inventory of 817 pieces may be available through existing stock channels, but this part is no longer in active production. The 2-644486-5 is the active equivalent with 4132 pieces currently in stock.

Q: Are both parts suitable for the same voltage and temperature applications?

A: Yes. Both the 644486-5 and 2-644486-5 are rated for 250VAC operation and function across the identical operating temperature range of -55°C to 105°C. Both parts meet UL94 V-0 flammability requirements and are suitable for general-purpose applications within these specifications.

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

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements. These connectors do not require desiccant packaging or controlled storage conditions.
