Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 644467-4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Number of positions (4)
• Pitch specification (0.156" / 3.96mm)
• Series designation (MTA-156)
• Cable termination method (IDC)
• Wire gauge compatibility (22 AWG)
• Contact type (Female Socket)
• Mounting configuration (Free Hanging In-Line)
• Fastening mechanism (Locking Ramp)
• Functional features (Feed Through, Polarizing Key)
• Contact finish thickness (80.0µin / 2.03µm)

Allowable Variation Parameters:

• Contact finish material (Tin-Lead vs. Tin)
• Packaging configuration
• RoHS compliance status
• REACH vendor status

The substitute part 3-644467-4 maintains complete electrical and mechanical compatibility with the main part while offering alternative contact finish and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

644467-4 (Tin-Lead Contact Finish): This part is suitable for applications where legacy system compatibility or specific tin-lead contact requirements are mandated. The part is RoHS non-compliant and carries REACH Affected status. Selection of this variant is appropriate for existing designs with established qualification history or where tin-lead contact properties are functionally required.

3-644467-4 (Tin Contact Finish): This substitute part is ROHS3 compliant, making it the preferred selection for new designs, procurement in regulated markets, and applications subject to RoHS directives. The tin contact finish maintains the same contact finish thickness specification (80.0µin / 2.03µm) and all electrical and mechanical parameters. This part offers superior compliance posture while maintaining complete functional equivalence. Inventory availability is higher at 910 pieces.

Both parts share identical electrical performance, mechanical compatibility, and connector geometry. Selection between them is determined by regulatory compliance requirements and contact finish specifications rather than functional capability.

Frequently Asked Questions (FAQ)

Q: Can 3-644467-4 be used as a direct replacement for 644467-4 in existing applications?

A: Yes. The 3-644467-4 maintains complete electrical and mechanical compatibility with 644467-4. Both connectors feature identical pitch (0.156"), position count (4), IDC termination method, wire gauge (22 AWG), mounting configuration, and fastening mechanism. The primary difference is contact finish material (tin versus tin-lead) and RoHS compliance status. Functional interchangeability is complete.

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

A: The main part (644467-4) features a tin-lead contact finish, while the substitute (3-644467-4) uses tin. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The tin-lead variant is RoHS non-compliant, whereas the tin variant is ROHS3 compliant. Contact finish material does not affect mechanical fit or electrical performance in IDC applications; selection is driven by regulatory and compliance requirements.

Q: Are there any packaging differences between these parts?

A: The main part (644467-4) packaging is not specified in the documentation. The substitute part (3-644467-4) is supplied in bulk packaging. Packaging configuration does not affect connector performance or compatibility. Bulk packaging may offer cost advantages for high-volume procurement.

Q: What does the base product number 644467 indicate?

A: The base product number 644467 identifies the core connector design within the MTA-156 series. The suffix "-4" designates the 4-position configuration. Both the main part and substitute share the same base product number, confirming they are variants of the same fundamental connector design.

Q: Is the polarizing key feature present on both parts?

A: Yes. Both 644467-4 and 3-644467-4 include polarizing key features and feed-through capability. These functional characteristics are identical across both parts.

Q: What is the moisture sensitivity level, and does it differ between parts?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements. This specification is identical for both the main part and substitute.

Q: Which part should be selected for new designs?

A: For new designs, the 3-644467-4 is the appropriate selection due to ROHS3 compliance. This part meets current regulatory requirements and provides superior compliance posture for products destined for regulated markets. The part maintains complete functional equivalence while offering better long-term compliance alignment.
