Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 644565-4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Number of positions (4)
• Pitch specification (0.100" / 2.54mm)
• Cable termination method (IDC)
• Wire gauge compatibility (28 AWG)
• Contact type (Female Socket)
• Mounting configuration (Free Hanging In-Line, Right Angle)
• Fastening mechanism (Locking Ramp)
• Series designation (MTA-100)
• Feed-through capability

The substitute part 3-644565-4 maintains full electrical and mechanical compatibility with the original 644565-4 across all specified parameters. The primary distinction between these parts is the contact finish specification and product status classification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 3-644565-4

The 3-644565-4 is the direct substitute for the obsolete 644565-4. Both parts share identical electrical and mechanical specifications across all critical connector parameters, including pitch, position count, termination method, wire gauge, and mounting configuration.

Compliance Considerations:

The 3-644565-4 holds active product status and carries RoHS compliance certification, whereas the 644565-4 is classified as obsolete and RoHS non-compliant. For new designs, system upgrades, or applications subject to RoHS regulatory requirements, the 3-644565-4 is the appropriate selection.

Contact Finish Distinction:

The 644565-4 specifies tin-lead contact finish, while the 3-644565-4 specifies tin contact finish. Both finishes maintain the same thickness specification of 80.0µin (2.03µm). The tin finish in the 3-644565-4 aligns with modern lead-free manufacturing standards and RoHS compliance requirements.

Supply Chain Status:

The 3-644565-4 maintains active inventory status with 1122 pieces available, compared to the 644565-4 with 971 pieces in stock. For ongoing procurement and long-term availability, the 3-644565-4 is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Can the 3-644565-4 be used as a direct replacement for the 644565-4 in existing assemblies?

A: Yes. The 3-644565-4 maintains full electrical and mechanical compatibility with the 644565-4 across all connector specifications, including pitch, position count, IDC termination method, 28 AWG wire gauge, mounting type, and fastening mechanism. Both parts are from the MTA-100 series and feature identical feed-through capability.

Q: What is the difference between the tin-lead finish on the 644565-4 and the tin finish on the 3-644565-4?

A: The 644565-4 uses tin-lead contact finish, while the 3-644565-4 uses tin contact finish. Both finishes are applied to the same thickness of 80.0µin (2.03µm). The tin finish on the 3-644565-4 reflects current manufacturing standards and supports RoHS compliance requirements.

Q: Why is the 644565-4 classified as obsolete?

A: The 644565-4 is listed as obsolete in the product lifecycle. The 3-644565-4 is the active equivalent part that replaces it. For new designs and ongoing production, the 3-644565-4 should be specified.

Q: Are there any packaging differences between these parts?

A: The 644565-4 packaging specification is not defined in the available data. The 3-644565-4 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance is a regulatory and manufacturing standard classification, not a functional or electrical parameter. The 3-644565-4 is RoHS compliant, making it suitable for applications and markets with RoHS requirements. The electrical and mechanical performance of both parts is equivalent.

Q: Can I use these connectors with both discrete and ribbon cable?

A: Yes. Both the 644565-4 and 3-644565-4 support discrete or ribbon cable termination via IDC method at 28 AWG wire gauge.

Q: What does "Feed Through" mean for these connectors?

A: Feed Through indicates that the connector supports pass-through signal routing, allowing signals to be transmitted through the connector body while maintaining the connection interface.
