Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4-640433-1 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with Female Socket contacts
• Position Count & Pitch: 11 positions at 0.156" (3.96mm) pitch
• Termination Technology: IDC cable termination for 22 AWG wire
• Electrical Properties: Tin contact finish with 80.0µin (2.03µm) thickness
• Mechanical Form Factor: Single-row, free-hanging in-line mounting with closed-end design
• Series Compatibility: MTA-156 series designation

Substitute parts must maintain identical values across all parameters listed above to ensure direct functional replacement without circuit redesign or mechanical rework.

Engineering Selection Recommendations

Primary Selection: 4-640433-1

The 4-640433-1 is the recommended primary choice for new designs and ongoing production. This part maintains Active product status with confirmed inventory availability of 868 pieces. RoHS Compliant certification and MSL 1 rating ensure compliance with current environmental and moisture sensitivity standards.

Substitute Selection: 4-644463-1

The 4-644463-1 qualifies as a functional equivalent based on identical electrical and mechanical parameters across all critical specifications. However, this part carries Obsolete product status, indicating discontinued manufacturing and limited future availability. The addition of a Polarizing Key feature provides enhanced mating security compared to the main part.

The 4-644463-1 maintains ROHS3 Compliant certification, which exceeds the RoHS Compliant requirement of the main part. Both parts share identical contact finish specifications, wire gauge compatibility, and termination methodology.

Selection Criteria:

• Use 4-640433-1 for new designs and standard production applications where Active product status and confirmed supply are required
• Use 4-644463-1 only when existing inventory of this part is available and design requirements permit the additional Polarizing Key feature
• Verify connector mating compatibility when transitioning between these parts due to the Polarizing Key difference

Frequently Asked Questions (FAQ)

Q: Can the 4-644463-1 be used as a direct replacement for the 4-640433-1 in existing assemblies?

A: The 4-644463-1 is electrically and mechanically compatible with the 4-640433-1 across all critical parameters including position count, pitch, wire gauge, and termination method. The addition of a Polarizing Key on the substitute part provides enhanced mating security. Physical compatibility depends on whether the mating connector accommodates the Polarizing Key feature.

Q: What is the significance of the Polarizing Key feature on the 4-644463-1?

A: The Polarizing Key is a mechanical feature that prevents incorrect mating orientation. This feature enhances assembly reliability by ensuring proper connector alignment during installation. Designs using the 4-640433-1 without a Polarizing Key must verify that mating connectors can accommodate this additional feature before substitution.

Q: Why is the 4-644463-1 listed as Obsolete?

A: Obsolete product status indicates that TE Connectivity has discontinued manufacturing of this part. While existing inventory may be available through authorized distributors, future supply cannot be guaranteed. New designs should specify the Active 4-640433-1 to ensure long-term component availability.

Q: Are there compliance differences between these two parts?

A: Both parts meet RoHS requirements, with the 4-644463-1 certified to ROHS3 standard and the 4-640433-1 to RoHS Compliant standard. ROHS3 represents a more recent compliance specification. Both parts carry identical MSL 1 ratings, ECCN EAR99 classification, and HTSUS codes.

Q: What wire gauges are compatible with these connectors?

A: Both the 4-640433-1 and 4-644463-1 are specified for 22 AWG wire. The IDC termination method accommodates both discrete and ribbon cable configurations at this gauge.

Q: How does the IDC termination method work with these connectors?

A: IDC (Insulation Displacement Contact) termination allows wire to be inserted directly into the connector without stripping insulation. The connector contacts pierce the wire insulation and establish electrical connection. This method is compatible with both discrete individual wires and flat ribbon cable at 22 AWG specification.

Q: What is the pitch specification and why is it important?

A: The 0.156" (3.96mm) pitch specifies the center-to-center distance between adjacent contact positions. This dimension is critical for mechanical compatibility with mating connectors and PCB layouts. Both substitute parts maintain identical pitch specifications.

Q: Can these connectors be used in applications requiring high moisture resistance?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. These connectors are suitable for applications without moisture-related component restrictions.
