Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BTH-090-01-L-D-A-TR is determined by equivalence in the following critical parameters:

• Number of Positions: 180
• Pitch: 0.020" (0.50mm)
• Number of Rows: 2
• Connector Type: Header, Outer Shroud Contacts
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Contact Finish Thickness: 10.0µin (0.25µm)
• Height Above Board: 0.168" (4.27mm)
• Mated Stacking Height: 5mm
• Features: Board Guide
• Base Product Number: BTH-090
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

The identified substitute part differs only in packaging format (Tray versus Tape & Reel), which does not affect electrical or mechanical performance in the application.

Parameter Comparison

Engineering Selection Recommendations

Both the BTH-090-01-L-D-A-TR and BTH-090-01-L-D-A maintain Active product status with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and supply chain logistics. The Tape & Reel format (TR) is optimized for automated assembly processes, while the Tray format accommodates alternative handling and distribution workflows. Both parts carry ROHS3 compliance and unlimited moisture sensitivity rating, ensuring equivalent performance in regulated applications. Inventory availability may influence selection, with the Tray variant currently showing higher stock levels.

Frequently Asked Questions (FAQ)

Q: Can BTH-090-01-L-D-A be used as a direct replacement for BTH-090-01-L-D-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. BTH-090-01-L-D-A uses Tray packaging while BTH-090-01-L-D-A-TR uses Tape & Reel packaging. This distinction affects handling and assembly processes but not component performance.

Q: What determines substitution eligibility for this connector?

A: Substitution is valid when the following parameters remain constant: 180 positions, 0.020" (0.50mm) pitch, 2-row configuration, Header type with outer shroud contacts, surface mount mounting, gold contact finish at 10.0µin thickness, 0.168" height above board, 5mm mated stacking height, board guide features, and ROHS3 compliance with MSL 1 rating.

Q: Does packaging format affect PCB assembly compatibility?

A: Packaging format affects assembly line equipment compatibility and handling procedures but does not alter the connector's electrical or mechanical interface with the PCB. Tape & Reel format integrates with automated pick-and-place systems, while Tray format requires manual or alternative handling methods.

Q: Are both parts suitable for high-reliability applications?

A: Both parts carry identical compliance certifications including ROHS3 status and unlimited moisture sensitivity rating (MSL 1), making them suitable for equivalent reliability requirements.

Q: What is the significance of the Base Product Number BTH-090?

A: The Base Product Number BTH-090 identifies the core connector family. Variations in the full part number (such as packaging designation) represent different configurations of the same fundamental product design.
