171-009-202-021 D-Sub 9 Position Panel Mount Receptacle Connector

Part Overview

The 171-009-202-021 is a 9 position D-Sub receptacle connector manufactured by NorComp Inc., designed for panel mount applications with female socket contacts. This connector is part of the 171 series and features solder cup termination suitable for electronic assemblies requiring reliable D-Sub connectivity. The part is currently in active production with 1089 units available in new original stock condition.

Alternative models become necessary when specific application requirements demand different flange configurations, mounting styles, or when sourcing constraints require cross-manufacturer compatibility within the D-Sub 9 position receptacle category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 171-009-202-021 is determined by the following critical parameters: connector style (D-Sub), connector type (receptacle with female sockets), number of positions (9), shell size (1/DE/E), and termination method (solder cup). All qualified substitutes maintain these core electrical and mechanical characteristics.

The substitute parts are grouped into two categories based on flange feature differences:

Category 1 - NorComp Series 171 (Cable Side and Mating Side Flanges): Parts 171-009-203L021 and 171-009-203L031 are direct NorComp alternatives differing only in flange location (cable side versus mating side), maintaining identical electrical performance and material specifications.

Category 2 - Cross-Manufacturer Alternatives: Parts 628-009-222-042 (Mercury United Electronics) and M24308/1-1F (Cinch Connectivity Solutions) provide functional equivalence with variations in mounting style, contact material, and operating temperature ranges while preserving the 9 position D-Sub receptacle configuration.

Parameter Comparison

Engineering Selection Recommendations

NorComp Series 171 Substitutes (171-009-203L021, 171-009-203L031): These parts maintain full compatibility with the 171-009-202-021 in terms of electrical performance, material composition, and regulatory compliance. Selection between these variants depends on flange location requirements: cable side flange (171-009-203L021) or mating side flange (171-009-203L031). Both are ROHS3 compliant and suitable for equivalent applications.

Mercury United Electronics 628-009-222-042: This substitute provides functional equivalence with the following considerations: mounting configuration differs (free hanging in-line versus panel mount), current rating is reduced to 3A per contact, and operating temperature range is narrower (-55°C ~ 85°C). This part is ROHS3 compliant and includes shielding features. Selection is appropriate when in-line mounting is required and current requirements do not exceed 3A per contact.

Cinch Connectivity Solutions M24308/1-1F: This military-grade alternative (MIL-C-24308 series) maintains panel mount configuration and 5A current rating with extended operating temperature range (-65°C ~ 125°C). However, this part is RoHS non-compliant and features yellow chromate plated cadmium finish with machined contacts. Selection is appropriate for military or aerospace applications where MIL-C-24308 compliance is specified and RoHS exemption is permitted.

Frequently Asked Questions (FAQ)

Q: Can 171-009-203L021 and 171-009-203L031 be used interchangeably with 171-009-202-021?

A: Yes, within the constraints of flange location requirements. Both parts are electrically and mechanically equivalent to the 171-009-202-021, differing only in flange position (cable side versus mating side). Panel mount applications can accommodate either configuration depending on PCB or chassis layout specifications.

Q: What is the primary limitation when substituting the 628-009-222-042?

A: The 628-009-222-042 uses free hanging in-line mounting rather than panel mount configuration, requiring different installation methodology. Additionally, the current rating is 3A per contact compared to 5A for the original part. Applications exceeding 3A per contact cannot use this substitute.

Q: Is the M24308/1-1F suitable for commercial applications?

A: The M24308/1-1F is RoHS non-compliant, making it unsuitable for applications requiring RoHS3 compliance. This part is designed for military and aerospace applications where MIL-C-24308 specification compliance is required and RoHS exemptions are applicable.

Q: What packaging formats are available for these substitutes?

A: 171-009-203L021 and 171-009-203L031 are supplied in tray packaging. The 628-009-222-042 is supplied in bulk packaging. The M24308/1-1F is supplied in bulk packaging. Packaging selection may affect procurement lead times and handling requirements.

Q: Are all substitutes suitable for the same operating temperature range?

A: No. The 171-009-202-021, 171-009-203L021, and 171-009-203L031 operate from -50°C to 100°C. The 628-009-222-042 operates from -55°C to 85°C (narrower upper limit). The M24308/1-1F operates from -65°C to 125°C (extended range). Application temperature requirements must be verified against each substitute's specifications.
