Key Parameters

Substitute Part Grouping Explanation

Substitution between the TE Connectivity 640433-4 and its identified equivalent is determined by strict alignment of the following critical parameters:

Critical Functional Parameters:

• Connector type (Receptacle)
• Number of positions (4)
• Pitch specification (0.156" / 3.96mm)
• Series designation (MTA-156)
• IDC cable termination method
• Wire gauge compatibility (22 AWG)
• Contact configuration (Female Socket)
• Mounting style (Free Hanging In-Line)

Application-Dependent Parameters:

• Contact finish material (Tin-Lead vs. Tin)
• Contact finish thickness (80.0µin maintained across variants)

Regulatory and Procurement Parameters:

• RoHS compliance status
• Packaging format (Bulk vs. Standard)
• Moisture Sensitivity Level (MSL 1 - Unlimited for both)

The substitute part 3-640433-4 maintains identical mechanical and electrical specifications while offering alternative compliance and packaging options.

Parameter Comparison

Engineering Selection Recommendations

Selection Criteria Based on Compliance and Certification:

The 640433-4 and 3-640433-4 are functionally and mechanically interchangeable for all IDC-terminated 4-position, 22 AWG applications within the MTA-156 series. Selection between these parts is determined by regulatory and procurement requirements:

Choose 640433-4 when:

• RoHS non-compliance is acceptable for the application
• Standard packaging format is required
• Tin-lead contact finish is specified by design requirements
• Legacy system compatibility is necessary

Choose 3-640433-4 when:

• RoHS3 compliance is mandated by regulatory or customer requirements
• Bulk packaging format is preferred for high-volume procurement
• Tin contact finish meets application specifications
• Environmental or sustainability standards require lead-free components

Both parts maintain identical electrical performance, mechanical dimensions, and IDC termination compatibility. The contact finish difference (Tin-Lead vs. Tin) does not affect functional interchangeability within standard IDC connector applications. Both parts carry MSL 1 rating, indicating no moisture sensitivity restrictions.

Frequently Asked Questions (FAQ)

Q: Are the 640433-4 and 3-640433-4 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.156"), number of positions (4), mounting type (free-hanging in-line), and contact configuration (female socket). They are directly interchangeable in any MTA-156 series 4-position IDC application.

Q: What is the difference between Tin-Lead and Tin contact finishes in these connectors?

A: The 640433-4 features tin-lead contact finish, while the 3-640433-4 features tin contact finish. Both maintain 80.0µin (2.03µm) finish thickness. The contact finish difference reflects RoHS compliance status rather than functional performance in standard IDC applications.

Q: Which part should I select for RoHS-compliant applications?

A: The 3-640433-4 is RoHS3 compliant and must be selected for applications requiring RoHS compliance. The 640433-4 is RoHS non-compliant and is not suitable for RoHS-regulated applications.

Q: Does packaging format affect connector performance?

A: No. The difference between standard and bulk packaging is purely a procurement consideration. Both 640433-4 and 3-640433-4 deliver identical connector performance regardless of packaging format.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both the 640433-4 and 3-640433-4 support IDC termination with discrete or ribbon cable at 22 AWG wire gauge.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard storage and handling procedures apply.

Q: Are there any electrical performance differences between these substitute parts?

A: No. Both connectors deliver identical electrical performance. All critical electrical parameters including contact resistance, current rating, and voltage specifications are equivalent across the 640433-4 and 3-640433-4.

Q: What export classifications apply to these connectors?

A: Both parts are classified under ECCN EAR99 and HTSUS code 8536.69.8000, indicating standard commercial connector classification with no additional export restrictions.
