Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1658043-2 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Connector Type: Receptacle, Center Strip Contacts
• Number of Positions: 80
• Pitch: 0.031" (0.80mm)
• Number of Rows: 2
• Mounting Type: Surface Mount
• Contact Finish: Gold with Flash thickness
• Height Above Board: 0.128" (3.25mm)
• Mated Stacking Heights: 5mm through 30mm range
• Features: Board Guide and Ground Bus (Plane)
• Series: MICTOR SB
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The substitute part 2-1658043-2 satisfies all specified parameters and is therefore a valid equivalent for the main part number 1658043-2.

Frequently Asked Questions (FAQ)

Q: Are parts 1658043-2 and 2-1658043-2 electrically interchangeable?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, including 80 positions, 0.031" (0.80mm) pitch, gold flash contact finish, and center strip contact configuration. They are direct electrical substitutes.

Q: Do these parts have identical mechanical dimensions?

A: Yes. Both parts share identical mechanical specifications: 2-row configuration, 0.128" (3.25mm) height above board, and support the same mated stacking heights from 5mm to 30mm. They are mechanically interchangeable.

Q: Are both parts suitable for surface mount assembly?

A: Yes. Both 1658043-2 and 2-1658043-2 are surface mount connectors with board guide and ground bus features. They are compatible with standard SMD assembly processes.

Q: What is the significance of the MICTOR SB series designation?

A: MICTOR SB is the product series classification for both parts. This designation indicates the connector family and design standard. Both parts belong to the same series and maintain full compatibility.

Q: Do these parts require special handling for moisture sensitivity?

A: No. Both parts carry MSL 1 rating, which indicates unlimited moisture sensitivity tolerance. Standard handling and storage procedures are sufficient without specialized moisture control measures.

Q: Can I use part 2-1658043-2 as a direct replacement for 1658043-2 in existing designs?

A: Yes. All electrical, mechanical, and compliance parameters are identical. The part 2-1658043-2 is a direct substitute requiring no design modifications.

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

A: The part numbers differ only in their numeric prefix (1658043-2 versus 2-1658043-2). All functional and physical specifications are identical. The difference reflects internal TE Connectivity part numbering conventions.

Q: Are both parts RoHS3 compliant?

A: Yes. Both 1658043-2 and 2-1658043-2 carry ROHS3 compliance certification, confirming conformance to current RoHS regulations.
