Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 644489-8 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)
• Pitch spacing (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding style (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact finish at mating surface (Gold)
• Voltage rating (250VAC minimum)
• Operating temperature range (-55°C ~ 105°C minimum)
• Flammability rating (UL94 V-0)

Parts are grouped into two categories: direct manufacturer equivalents from TE Connectivity and cross-manufacturer alternatives that satisfy all critical electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 2-644489-8 (Direct Manufacturer Equivalent)

The 2-644489-8 is a direct equivalent from TE Connectivity AMP Connectors within the same MTA-100 series. This part maintains identical electrical and mechanical specifications to the main part 644489-8, including contact dimensions, pitch spacing, voltage rating, and operating temperature range. The primary distinction is RoHS compliance status: the 2-644489-8 is RoHS Compliant with REACH Unaffected status, whereas the original 644489-8 is RoHS non-compliant. The contact finish on the post differs slightly (Tin versus Tin-Lead), reflecting modern lead-free manufacturing standards. This substitute is appropriate for applications requiring RoHS compliance or when the original part is unavailable.

Molex 0901362208 (Cross-Manufacturer Alternative)

The Molex 0901362208 from the C-Grid III 90136 series satisfies all critical electrical and mechanical parameters: 8-position header, 0.100" (2.54mm) pitch, through-hole right-angle mounting, shrouded 4-wall configuration, solder termination, gold-plated mating contacts, and UL94 V-0 flammability rating. This part is currently active in production with substantial inventory availability (3034 units). Notable differences include fastening type (Latch Holder versus Friction Lock), contact material (Brass versus Copper Alloy), insulation material composition (Glass Filled Polyester), and contact dimensions (0.266" mating length versus 0.200", 0.114" post length versus 0.130"). The Molex part is ROHS3 Compliant and REACH Unaffected. Operating temperature and voltage ratings are not specified for this part. Selection of the Molex alternative requires confirmation that the dimensional and fastening differences are compatible with the target application's PCB layout and mating connector specifications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-644489-8 be used as a direct replacement for 644489-8?

A: Yes. The 2-644489-8 maintains identical electrical and mechanical specifications within the MTA-100 series, including pitch spacing (0.100" / 2.54mm), contact configuration (8-position male pin header), mounting style (through-hole right-angle), and voltage/temperature ratings (250VAC, -55°C ~ 105°C). The primary difference is RoHS compliance status. Both parts are classified as obsolete.

Q: What are the key differences between the TE Connectivity and Molex alternatives?

A: The Molex 0901362208 differs in fastening mechanism (Latch Holder versus Friction Lock), contact material (Brass versus Copper Alloy), contact dimensions (0.266" mating length versus 0.200", 0.114" post length versus 0.130"), insulation height (0.284" versus 0.343"), and insulation material composition (Glass Filled Polyester versus standard Polyester). The Molex part is currently active in production, whereas both TE Connectivity parts are obsolete. Operating temperature and voltage specifications are not provided for the Molex part.

Q: Are the contact dimensions critical for substitution?

A: Contact dimensions affect mating depth and engagement characteristics. The TE Connectivity parts (644489-8 and 2-644489-8) share identical contact dimensions (0.200" mating length, 0.130" post length). The Molex 0901362208 has longer mating contacts (0.266") and shorter post contacts (0.114"), which may affect compatibility with existing mating connectors or PCB layouts. Verification of mating connector specifications is required before selecting the Molex alternative.

Q: What is the significance of the fastening type difference?

A: The original TE Connectivity parts use Friction Lock fastening, while the Molex alternative uses Latch Holder fastening. These mechanisms provide different retention characteristics and may not be interchangeable with existing mating connectors. The fastening type must be compatible with the corresponding receptacle connector in the application.

Q: Does RoHS compliance affect functional performance?

A: RoHS compliance reflects manufacturing process changes, primarily the elimination of lead from solder finishes. The 2-644489-8 (RoHS Compliant) uses Tin post finish, while the original 644489-8 (RoHS non-compliant) uses Tin-Lead. Both maintain equivalent electrical performance and contact reliability. RoHS compliance is a regulatory and supply chain consideration rather than a functional performance factor.

Q: Can the Molex 0901362208 be used in automotive applications?

A: The Molex 0901362208 is listed for Automotive and General Purpose applications. However, the original TE Connectivity 644489-8 is specified only for General Purpose applications. If the target application is automotive, the Molex part's automotive qualification may provide additional assurance, but compatibility with existing mating connectors and PCB specifications must be confirmed.

Q: What inventory considerations apply to these substitutes?

A: The original 644489-8 has 940 units in stock, the TE Connectivity 2-644489-8 has 820 units, and the Molex 0901362208 has 3034 units available. The Molex part offers significantly higher inventory availability and active production status, making it suitable for long-term supply continuity. Both TE Connectivity parts are obsolete, limiting future availability.

Q: Are there any compliance or certification differences?

A: All three parts carry UL94 V-0 flammability ratings and MSL 1 (Unlimited) moisture sensitivity levels. The 2-644489-8 and 0901362208 are both RoHS3/RoHS Compliant and REACH Unaffected, whereas the original 644489-8 is RoHS non-compliant with undefined REACH status. For applications requiring current regulatory compliance, the 2-644489-8 or 0901362208 are appropriate selections.
