Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-644488-3 is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Connector type classification (Header)
• Contact type (Male Pin)
• Position count (13 positions)
• Mating pitch specification (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Operating temperature range (-55°C ~ 105°C)
• Voltage rating (250VAC)
• Series designation (MTA-100)

The substitute part 3-644488-3 satisfies all critical matching parameters. Both connectors share identical mechanical and electrical specifications within the MTA-100 series. The primary distinction between these parts is product status and contact finish composition, with the substitute offering active availability and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The 3-644488-3 serves as the direct substitute for the obsolete 1-644488-3. Both parts maintain identical mechanical and electrical specifications within the MTA-100 series, ensuring functional compatibility in board-to-cable/wire interconnection applications.

Product Status Consideration: The 1-644488-3 is classified as obsolete, while the 3-644488-3 maintains active product status. Active status ensures ongoing manufacturer support, documented availability, and continued compliance with current industry standards.

Compliance Advantage: The 3-644488-3 achieves RoHS compliance, whereas the 1-644488-3 is RoHS non-compliant. This distinction reflects the contact finish composition difference: the substitute employs pure tin plating on both mating and post contacts, compared to the tin-lead finish of the original part. This change aligns with current environmental and regulatory requirements for electronic component manufacturing.

Functional Equivalence: All critical electrical parameters remain constant between the two parts: 250VAC voltage rating, -55°C to 105°C operating temperature range, UL94 V-0 flammability rating, and identical mechanical dimensions. The connector maintains its 13-position, 0.100" pitch configuration with through-hole, right-angle mounting and solder termination across both variants.

For new designs or component replenishment, the 3-644488-3 is the appropriate selection. For legacy system maintenance requiring exact historical specifications, the 1-644488-3 remains functionally equivalent where available inventory permits.

Frequently Asked Questions (FAQ)

Q: Can the 3-644488-3 directly replace the 1-644488-3 in existing applications?

A: Yes. The 3-644488-3 is a direct substitute with identical mechanical and electrical specifications. Both connectors feature 13 positions, 0.100" (2.54mm) pitch, through-hole right-angle mounting, solder termination, and operate across -55°C to 105°C with 250VAC rating. The primary differences are product status and contact finish composition.

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

A: The 1-644488-3 uses tin-lead contact finish, while the 3-644488-3 uses pure tin finish. This difference reflects RoHS compliance requirements. The tin finish on the 3-644488-3 maintains equivalent electrical and mechanical performance while meeting current environmental regulations. Both finishes provide adequate corrosion resistance and conductivity for general-purpose applications.

Q: Why is the 1-644488-3 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. The 3-644488-3 represents the current active equivalent within the MTA-100 series, offering the same functionality with updated compliance certifications.

Q: Are there packaging differences between these connectors?

A: The 1-644488-3 packaging specification is not provided in available documentation. The 3-644488-3 is supplied in bulk packaging. For specific packaging requirements, consult the manufacturer's current data sheets or contact the supplier directly.

Q: What applications are these connectors suitable for?

A: Both the 1-644488-3 and 3-644488-3 are classified for general-purpose applications. The 13-position, 0.100" pitch header configuration with board-to-cable/wire style makes these connectors suitable for standard interconnection requirements in industrial, consumer, and commercial electronic equipment operating within the specified temperature and voltage ranges.

Q: Is the 3-644488-3 compatible with the same mating connectors as the 1-644488-3?

A: Yes. Both parts share identical pitch (0.100" / 2.54mm), position count (13), and shrouding configuration (Shrouded - 4 Wall). They are mechanically and electrically compatible with the same mating connectors and cable assemblies designed for the MTA-100 series.

Q: What is the current availability status of these parts?

A: The 1-644488-3 is obsolete with limited remaining inventory. The 3-644488-3 maintains active product status with current manufacturing support and availability through authorized distributors.
