BTH-090-02-L-D-A-K Equivalent & Substitute Parts

Part Overview

The BTH-090-02-L-D-A-K is a 180 Position Connector Header manufactured by Samtec Inc., designed for surface mount applications with outer shroud contacts and gold plating. This rectangular connector operates at a 0.020" (0.50mm) pitch with a 2-row configuration and board guide features. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when inventory constraints, lead time requirements, or procurement preferences necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the BTH-090-02-L-D-A-K are identified based on strict parametric equivalence across all critical electrical and mechanical dimensions. The substitution criteria are limited to the following 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)
• Mated Stacking Height: 8mm
• Height Above Board: 0.286" (7.26mm)
• Features: Board Guide
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the BTH-090-02-L-D-A-K and BTH-090-02-L-D-A maintain Active product status with identical compliance certifications. The BTH-090-02-L-D-A is a direct parametric equivalent suitable for applications requiring the specified 180-position, 0.020" pitch surface mount header with gold contacts and board guide features. Selection between these parts may be determined by inventory availability, packaging preferences, or procurement lead times, as all electrical and mechanical parameters are equivalent. Both parts satisfy ROHS3 compliance and REACH unaffected status requirements.

Frequently Asked Questions (FAQ)

Q: Can BTH-090-02-L-D-A replace BTH-090-02-L-D-A-K in production designs?

A: Yes. The BTH-090-02-L-D-A is a parametric equivalent with identical electrical and mechanical specifications, including position count, pitch, mounting type, contact finish, and physical dimensions.
