Parameter Comparison

Engineering Selection Recommendations

4-175778-9 (Main Part): This part is suitable for applications requiring a yellow housing with polyamide insulation material and an operating temperature range of -30°C to 105°C. The part maintains active product status with full RoHS compliance and unlimited moisture sensitivity rating.

179228-9 (Substitute): This substitute provides identical mechanical and electrical interface specifications with natural housing color and polyamide insulation material. The operating temperature range is -55°C to 85°C, which is narrower than the main part. This part is appropriate for applications requiring extended low-temperature performance below -30°C but with maximum operating temperature limited to 85°C. Active product status and RoHS compliance are maintained.

440129-9 (Substitute): This substitute is from the High Performance Interconnect (HPI) series with thermoplastic insulation material and natural housing color. The operating temperature range is -25°C to 105°C, providing the same upper temperature limit as the main part with slightly reduced low-temperature capability. This part is appropriate for applications requiring thermoplastic insulation properties. Active product status and RoHS compliance are maintained.

All three parts are active products with RoHS compliance and unlimited moisture sensitivity rating, supporting direct substitution based on application-specific requirements for insulation material, operating temperature range, and housing color.

Frequently Asked Questions (FAQ)

Q: Can 179228-9 be used as a direct replacement for 4-175778-9?

A: The 179228-9 provides identical electrical and mechanical interface specifications, including 9 positions, 2.00mm pitch, crimp termination, and free-hanging inline mounting. The primary differences are housing color (natural versus yellow) and operating temperature range (-55°C to 85°C versus -30°C to 105°C). Substitution is valid when the application does not require the upper temperature capability above 85°C and housing color is not a design constraint.

Q: Can 440129-9 be used as a direct replacement for 4-175778-9?

A: The 440129-9 provides identical electrical and mechanical interface specifications with 9 positions, 2.00mm pitch, crimp termination, and free-hanging inline mounting. The primary differences are insulation material (thermoplastic versus polyamide), housing color (natural versus yellow), and operating temperature range (-25°C to 105°C versus -30°C to 105°C). Substitution is valid when thermoplastic insulation material is acceptable and the application does not require operation below -25°C.

Q: What are the critical parameters that must match for substitution?

A: The following parameters must remain identical for functional substitution: connector type (receptacle), contact type (female socket), number of positions (9), pitch (2.00mm), number of rows (1), mounting type (free hanging in-line), and contact termination (crimp). All substitute parts maintain these specifications.

Q: Are there differences in compliance certifications between these parts?

A: All three parts are RoHS compliant and carry unlimited moisture sensitivity level (MSL 1). All parts are active products. The substitute parts maintain equivalent compliance status to the main part.

Q: How does insulation material affect part selection?

A: The main part 4-175778-9 and substitute 179228-9 use polyamide (PA66) nylon 6/6 insulation material. The substitute 440129-9 uses thermoplastic insulation material. Material selection depends on application requirements for chemical resistance, mechanical properties, and thermal performance. Both material types are qualified for the specified operating temperature ranges.

Q: What is the significance of operating temperature range differences?

A: The main part 4-175778-9 operates from -30°C to 105°C. Substitute 179228-9 operates from -55°C to 85°C, providing extended low-temperature capability but reduced maximum temperature. Substitute 440129-9 operates from -25°C to 105°C, matching the upper temperature limit with slightly reduced low-temperature capability. Selection depends on the specific thermal environment of the application.

Q: Does housing color affect electrical performance?

A: Housing color (yellow for 4-175778-9, natural for 179228-9 and 440129-9) is a visual identification feature and does not affect electrical performance or mechanical compatibility. Color selection may be driven by application documentation, assembly traceability, or design standards.
