Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 2-644486-9 is the direct equivalent substitute for the obsolete 644486-9 model. Both components share identical electrical and mechanical specifications within the MTA-100 series, ensuring pin-for-pin and footprint compatibility.

Product Status Consideration: The 644486-9 is classified as obsolete, while the 2-644486-9 maintains active product status with significantly higher inventory availability (2694 pieces versus 1053 pieces). Selection of the active substitute ensures long-term supply chain continuity.

Compliance Differentiation: The substitute part 2-644486-9 is ROHS3 compliant and REACH unaffected, whereas the main part is RoHS non-compliant with undefined REACH status. For applications subject to environmental regulations or customer compliance requirements, the substitute part satisfies current regulatory frameworks.

Contact Finish Specification: The primary technical distinction is the contact finish. The main part specifies tin-lead finish on both mating and post surfaces, while the substitute specifies tin finish. Both finishes are compatible with standard solder termination processes and maintain equivalent electrical performance within the specified voltage and temperature operating ranges.

Frequently Asked Questions (FAQ)

Q: Are the 644486-9 and 2-644486-9 pin-for-pin compatible?

A: Yes. Both components feature identical 9-position configurations with 0.100" (2.54mm) pitch, square contact geometry, and overall contact dimensions of 0.440" (11.18mm). PCB footprints and mating interface specifications are equivalent.

Q: What is the significance of the contact finish difference between tin-lead and tin?

A: Both tin-lead and tin finishes provide equivalent electrical conductivity and solder wettability for through-hole termination applications. The tin finish on the substitute part reflects current manufacturing standards and environmental compliance requirements. Functional performance in the specified voltage (250VAC) and temperature (-55°C ~ 105°C) ranges is identical.

Q: Why is the 2-644486-9 classified as active while the 644486-9 is obsolete?

A: The 2-644486-9 represents the current production variant within the MTA-100 series. The obsolete designation of 644486-9 indicates discontinuation of that specific part number, with the 2-644486-9 serving as the active replacement maintaining full electrical and mechanical compatibility.

Q: Does the RoHS3 compliance of the substitute part affect compatibility?

A: No. RoHS3 compliance of the 2-644486-9 indicates adherence to current environmental regulations and does not alter electrical or mechanical performance. The substitute part operates identically to the non-compliant main part across all specified parameters.

Q: What packaging differences exist between these parts?

A: The main part 644486-9 packaging specification is not defined in the provided data. The substitute part 2-644486-9 is supplied in bulk packaging. Confirm packaging requirements with procurement specifications for your application.

Q: Can the 2-644486-9 be used in existing designs specified for 644486-9?

A: Yes. The substitute part maintains full compatibility across electrical ratings (250VAC), mechanical dimensions, contact configuration (9-position, 2.54mm pitch), operating temperature range (-55°C ~ 105°C), and termination method (solder). Direct substitution is supported without design modification.
