Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 644488-5 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 5
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Friction Lock
• Operating Temperature Range: -55°C ~ 105°C
• Voltage Rating: 250VAC
• Material Flammability Rating: UL94 V-0
• Series: MTA-100

The substitute part 2-644488-5 meets all mandatory matching parameters and is therefore classified as a direct equivalent. The primary distinction between the main part and its substitute relates to product status, packaging configuration, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 2-644488-5 is the direct equivalent substitute for the obsolete 644488-5. Both parts share identical electrical and mechanical specifications, including connector configuration, pitch spacing, contact geometry, operating temperature range, and voltage rating.

The primary differentiators between the main part and its substitute are:

Product Status: The 644488-5 is classified as obsolete, while the 2-644488-5 maintains active product status. Active status ensures ongoing availability, manufacturing support, and supply chain continuity.

Regulatory Compliance: The 2-644488-5 is ROHS3 compliant and REACH unaffected, whereas the 644488-5 is RoHS non-compliant with vendor-undefined REACH status. For applications subject to environmental regulations or customer requirements mandating RoHS compliance, the 2-644488-5 is the appropriate selection.

Contact Finish: The 644488-5 features Tin-Lead contact finish on both mating and post surfaces. The 2-644488-5 uses Tin contact finish. Both finishes provide equivalent electrical performance and corrosion resistance for the specified operating conditions.

Packaging: The 2-644488-5 is supplied in bulk packaging, offering flexibility for production environments requiring high-volume component distribution.

For new designs, legacy system support, or applications requiring RoHS-compliant components, the 2-644488-5 is the recommended selection. For applications with no regulatory compliance requirements and where existing inventory of 644488-5 is available, the main part remains functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Are the 644488-5 and 2-644488-5 mechanically interchangeable?

A: Yes. Both parts are mechanically interchangeable. They share identical mounting type (through-hole, right-angle), shrouding configuration (shrouded 4-wall), contact geometry (square shape), and dimensional specifications including contact length, insulation height, and pitch spacing.

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

A: The 644488-5 uses Tin-Lead contact finish, while the 2-644488-5 uses Tin contact finish. Both finishes provide equivalent electrical conductivity and corrosion resistance for the specified operating temperature range (-55°C to 105°C) and voltage rating (250VAC). The Tin finish in the 2-644488-5 aligns with RoHS3 compliance requirements.

Q: Why is the 644488-5 listed as obsolete?

A: The 644488-5 is classified as obsolete product status. The 2-644488-5 is the active equivalent replacement. For ongoing production and new designs, the 2-644488-5 is the recommended part selection to ensure supply chain continuity and manufacturer support.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts meet the same electrical specifications: 250VAC voltage rating, -55°C to 105°C operating temperature range, and UL94 V-0 flammability rating. The 2-644488-5 is compliant with RoHS3 and REACH regulations, making it suitable for applications subject to environmental requirements.

Q: Are these parts compatible with MTA-100 series receptacles?

A: Yes. Both the 644488-5 and 2-644488-5 are part of the MTA-100 series and are compatible with MTA-100 series receptacles. The 0.100" (2.54mm) pitch spacing and 5-position configuration ensure mating compatibility with corresponding MTA-100 receptacle connectors.

Q: What is the current rating for these connectors?

A: The current rating varies by wire gauge. The connector specifications do not define a fixed current rating independent of the wire gauge used in the mating cable or wire assembly. Current capacity is determined by the wire gauge selected for the application.

Q: Can the 2-644488-5 be used as a direct replacement in existing assemblies designed for the 644488-5?

A: Yes. The 2-644488-5 is a direct equivalent substitute. All electrical, mechanical, and dimensional parameters are identical. The part can be used as a direct replacement in existing designs, assemblies, and applications without modification.

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

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life. No special moisture control measures are required during storage or handling.
