Substitute Part Grouping Explanation

Substitute parts for the 8-440129-2 are identified based on strict parametric equivalence across the following critical criteria:

Mandatory Matching Parameters:

  • Connector Type: Receptacle
  • Contact Type: Female Socket
  • Number of Positions: 2
  • Pitch: 0.079" (2.00mm)
  • Number of Rows: 1
  • Mounting Type: Free Hanging (In-Line)
  • Contact Termination: Crimp
  • MSL Rating: 1 (Unlimited)

Variable Parameters Permitting Substitution:

  • Color (Red, Black, Yellow)
  • Insulation Material (Thermoplastic, Polyamide PA66)
  • Operating Temperature Range (within application requirements)
  • Series designation (HPI, CT)
  • RoHS revision level (RoHS Compliant, ROHS3 Compliant)

The substitute parts 6-440129-2 and 4-179228-2 maintain full parametric compatibility with the main part across all mandatory criteria, enabling direct functional substitution in applications where color coding or thermal performance variations are acceptable.

Engineering Selection Recommendations

Primary Substitute: 6-440129-2

The 6-440129-2 is the closest functional equivalent to the 8-440129-2. Both parts share identical series designation (High Performance Interconnect HPI), insulation material (Thermoplastic), and operating temperature range (-25°C ~ 85°C). The only difference is color coding (Black versus Red). This part is ROHS3 Compliant and maintains full parametric compatibility. Selection of this substitute is appropriate when color differentiation is not a critical design requirement and ROHS3 compliance is required.

Secondary Substitute: 4-179228-2

The 4-179228-2 provides an alternative with extended operating temperature capability (-30°C ~ 105°C) and polyamide insulation material. This part belongs to the CT series and is ROHS3 Compliant. Selection of this substitute is appropriate for applications requiring higher thermal performance or when polyamide insulation properties are beneficial. The yellow color coding provides visual differentiation from the main part.

All three parts maintain Active product status and unlimited moisture sensitivity rating, ensuring continued availability and suitability for production environments.

Frequently Asked Questions (FAQ)

Q: Can the 6-440129-2 be used as a direct replacement for the 8-440129-2?

A: Yes. The 6-440129-2 maintains identical electrical and mechanical specifications across all critical parameters: 2-position receptacle, 2.00mm pitch, female socket contacts, crimp termination, and free-hanging in-line mounting. The difference is color coding (Black versus Red). Both parts are Active and RoHS compliant.

Q: What is the primary difference between the 4-179228-2 and the main part?

A: The 4-179228-2 differs in three areas: insulation material (Polyamide PA66 versus Thermoplastic), operating temperature range (-30°C ~ 105°C versus -25°C ~ 85°C), and color (Yellow versus Red). All other parameters, including pitch, position count, and contact type, are identical.

Q: Are these parts interchangeable in terms of mating with contacts?

A: Yes. All three parts are 2-position receptacle housings with 2.00mm pitch and crimp termination. They accept the same contact types and configurations. The housing color does not affect electrical or mechanical compatibility with standard 2.00mm pitch contacts.

Q: Which substitute should be selected for high-temperature applications?

A: The 4-179228-2 supports operating temperatures up to 105°C, compared to 85°C for the main part and 6-440129-2. Selection of the 4-179228-2 is appropriate when the application requires sustained operation above 85°C.

Q: Do all three parts have the same moisture sensitivity rating?

A: Yes. All three parts carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly.

Q: What is the difference in RoHS compliance between these parts?

A: The main part (8-440129-2) is RoHS Compliant. Both substitutes (6-440129-2 and 4-179228-2) are ROHS3 Compliant, representing a more recent revision of the RoHS directive. ROHS3 compliance includes RoHS requirements and is suitable for applications requiring current regulatory alignment.

Q: Can color coding be used to differentiate circuit functions?

A: Yes. The three parts provide distinct color options: Red (8-440129-2), Black (6-440129-2), and Yellow (4-179228-2). Color selection can be used for circuit identification or functional grouping within a system design.

Q: Are contacts included with these housing parts?

A: No. All three parts are housings only. Contacts must be sourced separately and crimped into the housing according to TE Connectivity specifications.
