Engineering Selection Recommendations

TE Connectivity 440133-9 (Parametric Equivalent)

The 440133-9 is a parametric equivalent within the TE Connectivity product family. It maintains identical electrical and mechanical specifications to the 4-171822-9 while offering an extended operating temperature range of -25°C to 105°C. This part carries ROHS3 compliance certification and is available in bulk packaging with significantly higher inventory levels (35,402 units). Selection of this part is appropriate when extended temperature performance is required or when standardization within the TE Connectivity connector portfolio is preferred.

Molex 0022011092 (Similar Manufacturer Part)

The 0022011092 from the Molex KK250/5051 series matches all critical parameters with the addition of a polarizing key feature. This part operates across -40°C to 105°C and includes ROHS3 compliance with REACH unaffected status. The contact type is specified as non-gendered rather than female socket. Selection of this part is appropriate when cross-manufacturer compatibility is acceptable and when the polarizing key feature provides design benefit.

Molex 0511910900 (Parametric Equivalent)

The 0511910900 from the Molex 51191 series is a parametric equivalent offering identical position count, pitch, and termination specifications. It operates across -40°C to 105°C with ROHS3 compliance and REACH unaffected status. This part maintains female socket contact type and is available with 3,782 units in inventory. Selection of this part is appropriate when extended temperature performance and cross-manufacturer sourcing are required.

All substitute parts maintain active product status and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the 440133-9 directly replace the 4-171822-9 in all applications?

A: Yes. The 440133-9 maintains identical connector type, position count, pitch, contact type, mounting configuration, and termination method. The extended operating temperature range (-25°C to 105°C versus -20°C to 95°C) provides additional performance margin. The color difference (natural versus blue) is a cosmetic variation without functional impact on connector performance.

Q: What is the difference between the Molex 0022011092 and 0511910900?

A: Both parts share identical pitch, position count, and mounting specifications. The 0022011092 features a polarizing key and is specified with non-gendered contact type, while the 0511910900 has female socket contacts without polarizing features. The 0022011092 operates across a wider temperature range (-40°C to 105°C). Selection depends on whether polarization is required for the application.

Q: Are all substitute parts RoHS compliant?

A: The 4-171822-9 is RoHS Compliant. All substitute parts carry ROHS3 Compliant certification, which is acceptable for applications requiring RoHS compliance. ROHS3 represents the current RoHS directive standard.

Q: Do the substitute parts include contacts?

A: No. All parts listed, including the main part and all substitutes, are housings only. Contacts are not included and must be sourced separately.

Q: What is the significance of the pitch specification in connector selection?

A: The 0.098" (2.50mm) pitch is a critical parameter that determines physical compatibility with mating connectors and contact spacing. All listed parts maintain this identical pitch specification, ensuring mechanical and electrical interchangeability within this parameter class.

Q: Can I use the Molex parts in applications originally designed for TE Connectivity connectors?

A: Compatibility depends on the specific application requirements. All parts maintain identical pitch, position count, and termination specifications. However, connector housings from different manufacturers may have subtle dimensional or keying differences. Physical verification is necessary to confirm fit within the specific application assembly.

Q: What does "Contacts Not Included" mean for these parts?

A: These part numbers reference connector housings only. The female socket contacts that insert into the housing must be ordered separately using the appropriate contact part numbers for the 2.50mm pitch specification.

Q: Why do some parts specify color while others do not?

A: Color specification depends on manufacturer documentation. The 4-171822-9 is specified as blue, the 440133-9 and 0022011092 as natural, and the 0511910900 has no color specification in the provided data. Color does not affect electrical or mechanical function.
