Parameter Comparison

Engineering Selection Recommendations

Both the main part number 2-1703773-1 and the substitute part number 1-1703773-1 are classified as Active product status with full RoHS3 compliance and MSL Level 1 rating. Selection between these parts is based on the following criteria:

Primary Selection Criteria:

• Color Requirement: Select 2-1703773-1 (Gray) when gray housing color is specified in design documentation or assembly requirements. Select 1-1703773-1 (Black) when black housing color is required.
• Inventory Availability: The substitute part 1-1703773-1 maintains higher inventory levels (1402 pcs) compared to the main part 2-1703773-1 (657 pcs), supporting supply chain continuity.
• Regulatory Compliance: Both parts satisfy identical RoHS3 and MSL requirements, permitting interchangeable selection from a compliance perspective.

Functional Equivalence: The parts are electrically and mechanically equivalent across all interface parameters, including contact pitch, row spacing, mounting configuration, and operating temperature range. Housing color does not affect electrical performance or mechanical fit within the connector system.

Frequently Asked Questions (FAQ)

Q: Can the substitute part 1-1703773-1 (Black) be used in place of the main part 2-1703773-1 (Gray)?

A: Yes, the substitute part is functionally equivalent across all electrical and mechanical parameters. The only difference is housing color. Selection depends on whether the application design specifies a particular color requirement. If color is not a functional constraint, either part provides identical performance.

Q: Are there any compatibility issues when substituting between these part numbers?

A: No compatibility issues exist. Both parts share identical connector type, position count, pitch, row spacing, mounting type, contact termination, fastening mechanism, insulation material, and operating temperature range. They are interchangeable from an interface and performance standpoint.

Q: What is the significance of the different part numbers 2-1703773-1 and 1-1703773-1?

A: The part numbers differ only in the first digit, which corresponds to the housing color designation within the TE Connectivity AMP Connectors naming convention. The "2" prefix indicates Gray color, while the "1" prefix indicates Black color. All other specifications remain identical.

Q: Do both parts have the same RoHS and MSL compliance?

A: Yes. Both 2-1703773-1 and 1-1703773-1 are ROHS3 Compliant with MSL Level 1 (Unlimited) rating. They satisfy identical regulatory and environmental requirements.

Q: Are contacts included with these connector housings?

A: No. Both part numbers are connector housings only. Contacts are not included and must be ordered separately as specified in the design documentation.

Q: What is the base product number for these parts?

A: The base product number for both 2-1703773-1 and 1-1703773-1 is 1703773. This base number identifies the core connector housing design within the Heavy Duty Sealed Connector Series, MCP 1.5K.

Q: Can these parts be used in applications requiring sealed connector performance?

A: Yes. Both parts feature sealed design characteristics, supporting applications requiring environmental protection and sealed interface performance across the -40°C to 140°C operating temperature range.
