Key Parameters

Substitute Part Grouping Explanation

Substitution of the 644462-5 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Receptacle)
• Number of positions (5)
• Pitch spacing (0.156" / 3.96mm)
• Number of rows (1)
• Contact type (Female Socket)
• Mounting configuration (Free Hanging In-Line)
• Polarizing key presence

Electrical Compatibility:

• Cable termination method (IDC)
• Wire gauge support (20 AWG)
• Wire type compatibility (Discrete or Ribbon Cable)
• Contact finish thickness (80.0µin / 2.03µm)

Environmental & Regulatory:

• Moisture Sensitivity Level (1 - Unlimited)
• Series designation (MTA-156)

The substitute part 3-644462-5 maintains full equivalence across all mechanical, electrical, and environmental parameters. The primary distinction is the contact finish composition (tin versus tin-lead) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Product Replacement:

The 3-644462-5 serves as the direct active-production equivalent to the obsolete 644462-5. Both connectors maintain identical mechanical and electrical specifications within the MTA-156 series, ensuring direct form-fit-function compatibility.

Regulatory Compliance Consideration:

The 644462-5 carries RoHS non-compliant status, while the 3-644462-5 is ROHS3 compliant. For applications subject to RoHS directives or requiring compliance documentation, the 3-644462-5 is the appropriate selection.

Contact Finish Distinction:

The 644462-5 features tin-lead contact finish, whereas the 3-644462-5 uses tin finish. Both maintain identical contact finish thickness (80.0µin / 2.03µm). The contact finish composition does not affect mechanical or electrical compatibility for IDC termination applications.

Availability & Inventory:

The 3-644462-5 is currently in active production status with documented inventory availability, whereas the 644462-5 is obsolete. For new procurement or ongoing supply requirements, the 3-644462-5 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the 3-644462-5 directly replace the 644462-5 in existing assemblies?

A: Yes. The 3-644462-5 maintains full mechanical and electrical equivalence to the 644462-5. Both connectors are 5-position receptacles with identical pitch (0.156"), IDC termination, 20 AWG wire gauge support, and mounting configuration. Direct substitution is supported.

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

A: The 644462-5 uses tin-lead contact finish, while the 3-644462-5 uses tin finish. Both maintain the same contact finish thickness (80.0µin / 2.03µm). For IDC termination applications, this distinction does not affect electrical or mechanical performance.

Q: Why is the 644462-5 classified as obsolete?

A: The 644462-5 is no longer in active production. The 3-644462-5 is the current active-production equivalent within the MTA-156 series.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance status reflects regulatory requirements and material composition standards, not connector functionality. The 3-644462-5 (ROHS3 compliant) is required for applications subject to RoHS directives. Both connectors are mechanically and electrically compatible.

Q: Are both connectors available in the same packaging?

A: The 644462-5 packaging is not specified in available documentation. The 3-644462-5 is supplied in bulk packaging. Confirm packaging requirements with procurement specifications.

Q: What wire types are compatible with these connectors?

A: Both the 644462-5 and 3-644462-5 support discrete or ribbon cable with 20 AWG wire gauge. IDC termination is the specified cable connection method.

Q: Is the polarizing key present on both connectors?

A: Yes. Both the 644462-5 and 3-644462-5 feature closed-end design with polarizing key, ensuring correct orientation during mating.
