6803W3K202201 D-Sub Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The 6803W3K202201 is a 3-position D-Sub combo receptacle connector manufactured by NorComp Inc., designed for panel mount applications with female sockets. This connector is part of the 680 series and is currently in stock with 824 units available. The part serves as a power distribution interface in applications requiring reliable D-Sub connectivity with solder cup termination.

Substitute parts become necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design requirements shift to alternative series offerings from the same manufacturer that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

The substitute part 680M3W3K203L201 qualifies as a direct equivalent based on the following critical parameters that determine substitution compatibility:

• Connector Type & Configuration: Both parts are D-Sub combo receptacles with female sockets
• Position Count: Both feature 3-position power configuration
• Shell Size & Layout: Both use 2 (DA, A) - 3W3 shell size and connector layout
• Mounting Interface: Both are panel mount connectors
• Termination Method: Both utilize solder cup termination
• Current Rating: Both rated for 20A operation
• Operating Temperature: Both support -55°C ~ 125°C range
• Compliance: Both are ROHS3 compliant

The substitute part belongs to the Power-D 680M series, representing an evolution within NorComp's D-Sub product line while maintaining full mechanical and electrical compatibility with the original 680 series specification.

Parameter Comparison

Engineering Selection Recommendations

Both the 6803W3K202201 and 680M3W3K203L201 are active, production-status components from NorComp Inc. with full ROHS3 compliance and REACH unaffected status. The substitute part offers equivalent electrical and mechanical performance with identical current ratings, temperature operating range, and connector geometry.

Selection between these parts should be based on:

• Availability: The substitute part (680M3W3K203L201) currently has higher inventory availability at 1140 units versus 824 units for the main part
• Series Continuity: The main part maintains the original 680 series designation, while the substitute represents the Power-D 680M series evolution
• Packaging: The substitute part is supplied in tray packaging, which may influence handling and assembly procedures
• Product Status: Both parts are active and supported by the manufacturer

No functional or performance differences exist between these parts for applications requiring 3-position D-Sub power connectors with 20A current capacity and solder cup termination.

Frequently Asked Questions (FAQ)

Q: Can 680M3W3K203L201 be used as a direct replacement for 6803W3K202201 in existing designs?

A: Yes. Both connectors share identical electrical specifications (20A current rating, -55°C ~ 125°C operating range), mechanical dimensions (3-position, 2 (DA, A) - 3W3 shell size), mounting interface (panel mount), and termination method (solder cup). No design modifications are required.

Q: Are there differences in contact or shell materials between these parts?

A: No. Both parts feature steel shells with nickel plating, gold-finished contacts, and PBT dielectric material. Material specifications are identical.

Q: What is the significance of the series designation change from 680 to Power-D 680M?

A: The Power-D 680M series represents a current product line evolution from NorComp Inc. while maintaining full backward compatibility with the original 680 series. The substitute part is the active production equivalent.

Q: Does the tray packaging of the substitute part affect compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. Tray packaging is a logistics consideration for handling and assembly processes but does not impact connector performance or interchangeability.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the basis for substitution compatibility between these parts?

A: Substitution is based on matching critical parameters: connector type (receptacle, female sockets), position count (3-position power), shell size and layout (2 (DA, A) - 3W3), mounting type (panel mount), termination method (solder cup), current rating (20A), and operating temperature range (-55°C ~ 125°C).
