Key Parameters

Substitute Part Grouping Explanation

Substitution for the 180-044-202-021 is based on strict electrical and mechanical parameter matching within the D-Sub high density connector category. The primary substitute, 180-044-203L021, maintains functional equivalence through identical specifications in the following critical parameters:

• 44-position configuration
• High density D-Sub receptacle design
• Female socket contact arrangement
• Panel mount installation method
• Solder cup termination
• 3-row (DB, B) shell layout

The substitute part differs only in packaging format (Tray versus unspecified packaging for the main part) and inventory source, while maintaining complete electrical and mechanical compatibility. Both parts belong to the NorComp 180 series and share the same base product number (180-044).

Parameter Comparison

Engineering Selection Recommendations

Both the 180-044-202-021 and its substitute 180-044-203L021 are functionally equivalent for 44-position D-Sub high density receptacle applications requiring panel mount installation with solder cup termination. The substitute part carries ROHS3 compliance certification and active product status, confirming ongoing manufacturer support and regulatory alignment.

Selection between these parts should be based on packaging requirements (Tray packaging for 180-044-203L021) and inventory availability. The substitute part's documented material specifications (steel nickel-plated shell, brass contacts with gold finish) and current rating (5A) provide additional technical clarity for design verification purposes.

Frequently Asked Questions (FAQ)

Q: Can 180-044-203L021 be used as a direct replacement for 180-044-202-021?

A: Yes. Both parts are 44-position D-Sub high density receptacles with identical connector type, mounting method, and termination style. They share the same base product number (180-044) within the NorComp 180 series.

Q: What is the primary difference between these two parts?

A: The main difference is packaging format. The 180-044-203L021 is supplied in Tray packaging, while the original part's packaging is not specified. Both maintain identical electrical and mechanical specifications for panel mount solder cup applications.

Q: Are there compliance differences between the parts?

A: The 180-044-203L021 is documented as ROHS3 compliant with active product status. Compliance information for the 180-044-202-021 is not provided in the available specifications.

Q: What is the contact configuration for these connectors?

A: Both parts feature 44 female socket contacts arranged in a 3-row (DB, B) high density D-Sub shell layout, suitable for signal transmission in panel mount installations.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, provided the design accommodates the specified packaging format. The electrical and mechanical interfaces are identical between both parts.
