BTH-090-03-L-D-A-K Equivalent & Substitute Parts

Part Overview

The BTH-090-03-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). Alternative equivalent parts may be required due to inventory availability, procurement lead times, or specific supply chain requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BTH-090-03-L-D-A-K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Position count (180 positions), pitch geometry (0.020" / 0.50mm), row configuration (2 rows), connector type classification (Header with Outer Shroud Contacts), mounting methodology (Surface Mount), contact material and finish (Gold at 10.0µin thickness), physical dimensions (0.404" height above board, 11mm mated stacking height), and board guide feature presence. Regulatory compliance markers including RoHS3 status and MSL rating must remain unchanged. The substitute part BTH-090-03-L-D-A meets all these criteria and qualifies as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the BTH-090-03-L-D-A-K and BTH-090-03-L-D-A maintain Active product status with full regulatory compliance. The BTH-090-03-L-D-A qualifies as a direct parametric equivalent based on complete alignment across all specified electrical, mechanical, and compliance parameters. Selection between these parts should be based on inventory availability and procurement lead time requirements, as no technical differentiation exists between them. Both parts carry ROHS3 compliance and REACH Unaffected status, ensuring regulatory suitability for equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can BTH-090-03-L-D-A be used as a direct replacement for BTH-090-03-L-D-A-K?
