Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 55733-201 is determined by strict parametric matching across electrical and mechanical dimensions. The following parameters must align identically for a part to function as a direct equivalent:

• Connector type: Differential Pair Array, Female
• Position count: 296 Signal (148 Pair)
• Pitch: 0.051" (1.30mm)
• Row configuration: 18 rows
• Mounting method: Surface Mount
• Contact finish: Gold at 30.0µin (0.76µm) thickness
• Height above board: 0.813" (20.64mm)
• Mated stacking height range: 25mm through 40mm
• Moisture sensitivity: MSL 1

The substitute parts identified—TE Connectivity AMP Connectors 1-1761617-5 and 6-1761617-5—meet all these parametric requirements and are therefore classified as parametric equivalents suitable for direct replacement in applications designed for the 55733-201.

Parameter Comparison

Engineering Selection Recommendations

All three parts—55733-201, 1-1761617-5, and 6-1761617-5—are active production components with identical electrical and mechanical specifications. Selection between them should be based on the following factors:

RoHS Compliance: The 6-1761617-5 (TE Connectivity) is ROHS3 compliant, while the 55733-201 and 1-1761617-5 are RoHS non-compliant. Applications subject to RoHS3 regulatory requirements must use the 6-1761617-5.

Availability: All three parts maintain adequate inventory levels. The 6-1761617-5 has the highest stock at 814 units, followed by the 55733-201 at 788 units, and the 1-1761617-5 at 780 units.

Series Compatibility: The 55733-201 belongs to the GIG-Array® and MezzSelect™ series, while both TE Connectivity equivalents belong to the STEP-Z series. Design documentation should confirm series interchangeability for the specific application.

Manufacturer Preference: Selection may depend on established supplier relationships, qualification history, or design documentation requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1761617-5 and 6-1761617-5 be used interchangeably with the Amphenol ICC 55733-201?

A: Yes, both TE Connectivity parts are parametric equivalents meeting all electrical and mechanical specifications of the 55733-201. They share identical position count, pitch, row configuration, mounting type, contact finish, and stacking height options. Direct substitution is supported from a technical standpoint.

Q: What is the difference between the two TE Connectivity substitute parts?

A: The 1-1761617-5 and 6-1761617-5 are identical in all electrical and mechanical parameters. The primary distinction is RoHS compliance status: the 6-1761617-5 is ROHS3 compliant, while the 1-1761617-5 is RoHS non-compliant. Selection depends on regulatory requirements for the target application.

Q: Are there any compatibility concerns when switching between the Amphenol ICC and TE Connectivity series?

A: The 55733-201 belongs to the GIG-Array® and MezzSelect™ series, while the TE Connectivity equivalents belong to the STEP-Z series. All parametric specifications align, but design documentation should be reviewed to confirm series interchangeability for the specific application context.

Q: What packaging format is used for these connectors?

A: All three parts are supplied in tray packaging, suitable for automated assembly processes and standard component handling procedures.

Q: Are moisture sensitivity considerations a factor in part selection?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply uniformly across all options.
