Key Parameters

Substitute Part Grouping Explanation

Substitution of the 644563-7 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (receptacle)
• Number of positions (7)
• Pitch spacing (0.100" / 2.54mm)
• Number of rows (1)
• Mounting configuration (free-hanging in-line and right-angle)
• Fastening mechanism (locking ramp)

Electrical Compatibility:

• Contact type (female socket)
• Cable termination method (IDC)
• Wire gauge support (24 AWG)
• Wire type compatibility (discrete or ribbon cable)
• Feed-through capability

Physical Characteristics:

• Series designation (MTA-100)
• Contact finish thickness (80.0µin / 2.03µm)
• Housing color (white)

The substitute part 3-644563-7 maintains full equivalence across all mechanical, electrical, and physical parameters. The primary distinction is the contact finish specification and product status.

Parameter Comparison

Engineering Selection Recommendations

The 3-644563-7 is the direct substitute for the obsolete 644563-7. Both parts share identical mechanical, electrical, and dimensional specifications within the MTA-100 series. The substitute part is currently in active production status, ensuring supply chain availability for new designs and replacement applications.

The primary technical distinction is the contact finish specification: the original part uses tin-lead plating, while the substitute uses tin plating. Both finishes maintain the same thickness specification of 80.0µin (2.03µm) and are compatible with IDC termination and 24 AWG wire applications.

The substitute part 3-644563-7 carries ROHS3 compliance certification, whereas the original part status is not applicable. This compliance designation reflects current manufacturing standards and regulatory requirements for electronic components.

Both parts maintain identical moisture sensitivity levels (MSL 1 - Unlimited), indicating no special storage or handling requirements during assembly and deployment.

Frequently Asked Questions (FAQ)

Q: Can the 3-644563-7 be used as a direct replacement for the 644563-7 in existing designs?

A: Yes. The 3-644563-7 maintains full mechanical and electrical compatibility with the 644563-7. All critical parameters including connector type, position count, pitch, contact configuration, termination method, and wire gauge specifications are identical. The parts are mechanically and functionally interchangeable.

Q: What is the difference between the tin-lead and tin contact finishes?

A: The 644563-7 features tin-lead contact plating, while the 3-644563-7 uses tin plating. Both finishes are applied to the same thickness specification (80.0µin / 2.03µm). The contact finish difference reflects manufacturing process updates and regulatory compliance evolution. Both finishes support IDC termination and are suitable for 24 AWG wire applications.

Q: Why is the 644563-7 listed as obsolete?

A: The 644563-7 is no longer in active production. The 3-644563-7 represents the current active equivalent part from TE Connectivity AMP Connectors. For new designs and ongoing supply requirements, the 3-644563-7 is the recommended selection.

Q: Are there any packaging differences between these parts?

A: The 644563-7 packaging specification is not defined in the available data. The 3-644563-7 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Does the ROHS3 compliance of the 3-644563-7 affect compatibility?

A: No. ROHS3 compliance indicates the substitute part meets current environmental and regulatory standards. This certification does not impact mechanical or electrical compatibility with the original part. The compliance status reflects manufacturing standards rather than functional capability.

Q: Can both parts be used interchangeably in the same assembly?

A: Yes. The 644563-7 and 3-644563-7 are mechanically and electrically equivalent. Both support free-hanging in-line and right-angle mounting configurations with locking ramp fastening. Both accommodate discrete or ribbon cable termination at 24 AWG wire gauge. Both provide feed-through capability within the MTA-100 series.

Q: What is the current inventory status for the substitute part?

A: The 3-644563-7 has 771 pieces of new original stock available. The 644563-7 has 732 pieces available but is obsolete and not recommended for new procurement.
