Key Parameters

Substitute Part Grouping Explanation

Substitution of the 553212-3 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Number of Positions: 50
• Number of Rows: 2
• Connector Type: Receptacle
• Mounting Type: Free Hanging (In-Line), Right Angle
• Connector Style: Outer Shroud Contacts
• Flange Feature: Housing/Shell (4-40)
• Series: CHAMP .085

Electrical Compatibility Parameters:

• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Moisture Sensitivity Level: 1 (Unlimited)

Functional Difference: The primary distinction between the main part and its substitute is the termination method. The 553212-3 utilizes IDC (Insulation Displacement Contact) termination, while the substitute part 5553212-3 employs Crimp termination. Both termination methods are functionally equivalent for establishing electrical connections within the same connector housing and pin configuration.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production: The substitute part 5553212-3 is the appropriate selection for new applications. This part maintains identical mechanical and electrical specifications to the 553212-3 while offering the following advantages:

• Active Product Status: The 5553212-3 is classified as active, ensuring continued availability and manufacturer support.
• RoHS Compliance: The substitute part meets RoHS compliance requirements, whereas the original 553212-3 is non-compliant. This compliance status is critical for applications subject to environmental regulations and industry standards.
• Termination Method: The crimp termination of the 5553212-3 provides equivalent electrical performance to the IDC termination of the original part. Crimp termination is widely supported by standard tooling and assembly processes.

For Legacy System Maintenance: The original 553212-3 remains available in inventory (983 pieces in stock) for applications requiring exact reproduction of existing assemblies or where IDC termination is specifically required by system design.

Frequently Asked Questions (FAQ)

Q: Can the 5553212-3 be used as a direct replacement for the 553212-3 in existing designs?

A: The 5553212-3 is mechanically and electrically compatible with the 553212-3 across all critical parameters including pin count, mounting configuration, contact finish, and housing specifications. The primary difference is the termination method (crimp versus IDC). Compatibility depends on whether the application's cable assembly and termination process can accommodate crimp termination instead of IDC termination.

Q: What is the significance of the RoHS compliance difference?

A: The 553212-3 is RoHS non-compliant, while the 5553212-3 is RoHS compliant. RoHS compliance is mandatory for products sold into markets with environmental regulations, including the European Union and many other jurisdictions. New designs should utilize the RoHS-compliant 5553212-3 to ensure regulatory compliance.

Q: Are the connector housings and pin configurations identical between these parts?

A: Yes. Both parts feature 50 positions arranged in 2 rows, identical outer shroud contact styling, gold contact finish at 30.0µin thickness, and the same flange feature (Housing/Shell 4-40). The physical connector interface is identical.

Q: What tooling differences exist between IDC and crimp termination?

A: IDC termination requires IDC-specific tooling that pierces insulation and establishes contact without stripping wire insulation. Crimp termination requires crimp tooling that compresses a contact onto stripped wire. Both methods are industry-standard, but require different assembly equipment and processes.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both the 553212-3 and 5553212-3 have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these connectors be used interchangeably in the same mating interface?

A: Yes. Both parts are receptacle connectors in the CHAMP .085 series with identical mechanical dimensions, mounting configurations, and pin layouts. They mate with the same plug connectors and occupy the same physical space in assemblies.
