Key Parameters

Substitute Part Grouping Explanation

The substitute part 552274-1 is electrically and mechanically equivalent to the main part 552318-1 based on the following critical parameters:

Matching Parameters:

• Connector type: Plug
• Position count: 36 positions
• Row configuration: 2 rows
• Mounting configuration: Free Hanging (In-Line)
• Termination technology: IDC
• Connector style: Center Strip Contacts
• Series designation: CHAMP .085
• Contact finish specification: Gold at 30.0µin (0.76µm)
• Functional features: Bail Lock

Difference: The primary distinction between these parts is packaging format. The main part 552318-1 is supplied in standard packaging, while the substitute 552274-1 is supplied in tray packaging. This packaging difference does not affect connector performance, electrical characteristics, or mechanical compatibility.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Are 552318-1 and 552274-1 electrically interchangeable?

A: Yes. Both parts are 36-position IDC plug connectors with identical electrical specifications, contact finish, and termination technology. They perform identically in circuit applications.

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

A: The packaging format. The 552318-1 uses standard packaging while the 552274-1 uses tray packaging. This difference does not affect connector performance or mechanical compatibility.

Q: Can I use 552274-1 as a direct replacement for 552318-1 in my assembly?

A: Yes. The connector itself is identical. Compatibility depends on whether your assembly process can accommodate tray packaging instead of standard packaging.

Q: Do both parts meet the same compliance standards?

A: Yes. Both 552318-1 and 552274-1 are ROHS3 compliant, REACH unaffected, and carry the same EAR99 export classification.

Q: Which part should I select if inventory is a concern?

A: Both parts are in active production with healthy inventory levels. The 552274-1 has slightly higher current stock (1090 pieces versus 985 pieces). Selection should be based on your packaging requirements and assembly process compatibility.

Q: Are the contact specifications identical?

A: Yes. Both parts feature gold-plated contacts with 30.0µin (0.76µm) finish thickness and identical bail lock features.
