Substitute Part Grouping Explanation

Substitution between the main part 552221-1 and the equivalent part 5552221-1 is based on electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical functional parameters: 24-position configuration, 2-row arrangement, through-hole solder termination, center strip contact style, board-side flange, and gold contact finish. The primary distinction between these parts is packaging format and compliance certification status.

The substitution logic is determined by the following key parameters:

• Number of Positions: 24
• Number of Rows: 2
• Connector Type: Plug
• Mounting Type: Through Hole
• Termination Method: Solder
• Connector Style: Center Strip Contacts
• Flange Feature: Board Side
• Contact Finish: Gold
• Series: CHAMP .085

Parameter Comparison

Engineering Selection Recommendations

Both 552221-1 and 5552221-1 are functionally equivalent 24-position D-Sub plug connectors suitable for through-hole solder applications. Selection between these parts should be based on the following criteria:

552221-1 (Main Part): Select this part number when bulk packaging is acceptable and RoHS non-compliant components are permitted in the application. This part offers higher inventory availability with 1,125 units in stock.

5552221-1 (Substitute): Select this part number when ROHS3 compliance is required for the end application or when tray packaging is specified. This part is ROHS3 compliant and suitable for applications with regulatory compliance requirements. Inventory availability is 770 units.

Both parts maintain identical electrical and mechanical specifications, including connector geometry, contact configuration, termination method, and contact finish. The choice between these parts is determined by packaging format preference and compliance certification requirements, not by functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are 552221-1 and 5552221-1 electrically interchangeable?

A: Yes. Both parts are 24-position D-Sub plug connectors with identical electrical specifications, including gold contact finish, center strip contact style, and solder termination. They function identically in circuit applications.

Q: What is the primary difference between these two part numbers?

A: The primary differences are packaging format and RoHS compliance status. The 552221-1 is supplied in bulk packaging and is RoHS non-compliant. The 5552221-1 is supplied in tray packaging and is ROHS3 compliant.

Q: Can I use 5552221-1 as a direct replacement for 552221-1 in my assembly?

A: Yes, provided that your application either requires or permits ROHS3 compliance. The mechanical and electrical specifications are identical, and both parts are rated for through-hole solder mounting on PCBs with identical board-side flange configuration.

Q: Does packaging format affect connector performance?

A: No. Packaging format (bulk versus tray) does not affect connector electrical or mechanical performance. The choice of packaging is based on handling, storage, and assembly process requirements.

Q: Which part should I specify for new designs?

A: For new designs, specify 5552221-1 if ROHS3 compliance is required or anticipated. If RoHS compliance is not a requirement, either part number is acceptable based on packaging and inventory availability preferences.

Q: Are there any differences in contact finish between these parts?

A: Both parts feature gold contact finish. The 552221-1 specifies a contact finish thickness of 30.0µin (0.76µm). Contact finish thickness for 5552221-1 is not specified in available documentation.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts are rated at MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
