Substitute Part Grouping Explanation

Substitution between the main part 1-640441-4 and the equivalent part 4-640441-4 is based on strict electrical and mechanical compatibility criteria. Both parts share identical specifications across all critical parameters that determine connector interchangeability:

Key Parameters for Substitution Compatibility:

• Connector type, position count, and pitch (0.100" / 2.54mm)
• Contact configuration (14-position female socket receptacle)
• Cable termination method (IDC for 24 AWG wire)
• Mounting orientation and fastening mechanism (free-hanging, right-angle, locking ramp)
• Physical features (closed-end design, white color)
• Moisture sensitivity rating (MSL 1)

The primary distinction between these parts is the contact finish specification and RoHS compliance status. The 1-640441-4 features tin-lead contact finish and is RoHS non-compliant, while the 4-640441-4 features tin contact finish and is ROHS3 compliant. Both contact finishes maintain the same thickness specification of 80.0µin (2.03µm), ensuring equivalent electrical performance and mating characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the 1-640441-4 and 4-640441-4 are active production parts from TE Connectivity and are electrically and mechanically interchangeable for applications requiring 14-position MTA-100 series IDC receptacle connectors with 24 AWG wire termination.

Selection Criteria:

The 4-640441-4 is the preferred selection for new designs and applications subject to RoHS3 compliance requirements. This part features tin contact finish and meets ROHS3 compliance standards while maintaining identical electrical performance and mechanical compatibility with the 1-640441-4.

The 1-640441-4 remains suitable for legacy systems, non-regulated applications, or designs where RoHS compliance is not a requirement. The tin-lead contact finish provides equivalent contact reliability and mating characteristics as the tin finish variant.

Both parts carry identical moisture sensitivity ratings (MSL 1), export classifications (EAR99), and tariff codes (8536.69.8000), indicating equivalent handling and regulatory treatment.

Frequently Asked Questions (FAQ)

Q: Are the 1-640441-4 and 4-640441-4 mechanically interchangeable?

A: Yes. Both parts are 14-position MTA-100 series receptacle connectors with identical pitch (0.100"), mounting type (free-hanging, right-angle), fastening mechanism (locking ramp), and closed-end design. They mate with the same complementary connector types and accept identical 24 AWG discrete or ribbon cable terminations via IDC method.

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

A: The 1-640441-4 features tin-lead contact finish, while the 4-640441-4 features tin contact finish. Both finishes are applied to the same thickness specification (80.0µin / 2.03µm) and provide equivalent electrical conductivity and contact reliability. The primary distinction is regulatory compliance: tin finish supports ROHS3 compliance, while tin-lead does not.

Q: Can I substitute the 4-640441-4 for the 1-640441-4 in existing designs?

A: Yes. The 4-640441-4 is a direct substitute for the 1-640441-4. All electrical and mechanical parameters are identical, including connector type, position count, pitch, mounting configuration, and cable termination method. The 4-640441-4 is suitable for retrofit or replacement applications.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: MSL 1 indicates the lowest moisture sensitivity level. These connectors have unlimited shelf life and do not require special moisture-controlled storage or handling procedures. They can be stored and handled under standard industrial conditions without degradation.

Q: Are both parts suitable for ribbon cable applications?

A: Yes. Both the 1-640441-4 and 4-640441-4 accept discrete or ribbon cable with 24 AWG wire gauge via IDC termination. The IDC method allows direct cable insertion without pre-stripping, making these connectors suitable for both discrete wire and ribbon cable harness applications.

Q: What is the packaging difference between these parts?

A: The 1-640441-4 is supplied in standard packaging, while the 4-640441-4 is supplied in bulk packaging. Both are new original stock from TE Connectivity. Packaging type does not affect electrical or mechanical performance.
