Substitute Part Grouping Explanation

The substitute part 172-E09-203R021 is classified as a direct manufacturer equivalent based on the following critical parameters:

• Connector Type & Configuration: Both parts are 9 Position D-Sub Receptacles with female socket contacts
• Shell Size & Layout: Identical shell size designation (1, DE/E layout)
• Mounting Method: Both are panel mount connectors
• Electrical Specifications: Matching 5A current rating and operating temperature range (-50°C ~ 100°C)
• Material & Finish Specifications: Steel shell with nickel plating and gold contact finish
• Compliance & Certifications: Both meet UL94 V-0 and ROHS3 requirements
• Termination Method: Solder cup termination on both parts

The primary difference is packaging: 172-E09-202-021 is supplied in standard packaging, while 172-E09-203R021 is supplied in Tray packaging. This distinction does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both 172-E09-202-021 and 172-E09-203R021 are Active status products from NorComp Inc. and are fully interchangeable for panel mount D-Sub receptacle applications requiring 9 positions with female socket contacts.

Selection between these parts should be based on packaging requirements and inventory availability:

• 172-E09-202-021: Select when standard packaging is required or preferred for your supply chain logistics
• 172-E09-203R021: Select when tray packaging is specified for automated assembly or bulk handling operations

Both parts satisfy identical electrical and mechanical specifications, including current rating, operating temperature range, and compliance certifications (UL94 V-0, ROHS3). The choice between them does not impact circuit performance or reliability.

Frequently Asked Questions (FAQ)

Q: Are 172-E09-202-021 and 172-E09-203R021 electrically identical?

A: Yes. Both parts are 9 Position D-Sub Receptacles with identical electrical specifications, including 5A current rating, -50°C to 100°C operating temperature range, and gold-plated contacts. They are direct functional equivalents.

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

A: The packaging format. 172-E09-202-021 uses standard packaging, while 172-E09-203R021 uses tray packaging. This distinction affects handling and logistics only, not electrical or mechanical performance.

Q: Can I use 172-E09-203R021 as a direct replacement for 172-E09-202-021 in my design?

A: Yes. Both parts have identical connector specifications, mounting method (panel mount), termination type (solder cup), and compliance certifications. They are interchangeable for all circuit applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are UL94 V-0 rated and ROHS3 compliant. They also share identical material specifications (steel shell with nickel plating, gold contact finish).

Q: Which part should I specify for high-volume production?

A: 172-E09-203R021 with tray packaging is typically preferred for high-volume automated assembly operations due to its packaging format. However, both parts are functionally equivalent and the choice depends on your assembly process requirements.
