BTH-050-02-L-D-A-TR Equivalent & Substitute Parts

Part Overview

The BTH-050-02-L-D-A-TR is a 100 position connector header manufactured by Samtec Inc., designed for surface mount applications with outer shroud contacts and gold plating. This rectangular connector operates at 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 identical electrical and mechanical parameters are maintained across the connector specification, ensuring direct interchangeability in surface mount assembly processes.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BTH-050-02-L-D-A-TR are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria include:

• Identical number of positions (100)
• Matching pitch specification (0.020" / 0.50mm)
• Same row configuration (2 rows)
• Identical connector type (Header, Outer Shroud Contacts)
• Matching mounting technology (Surface Mount)
• Equivalent contact finish and thickness (Gold, 10.0µin)
• Same height above board (0.286" / 7.26mm)
• Identical mated stacking height (8mm)
• Matching packaging format (Tape & Reel)
• Equivalent compliance certifications (RoHS3, REACH Unaffected)

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

Parameter Comparison

Engineering Selection Recommendations

Both the BTH-050-02-L-D-A-TR and BTH-050-02-L-D-A-K-TR maintain Active product status with identical compliance certifications. The BTH-050-02-L-D-A-K-TR offers higher inventory availability (1624 pcs vs. 1104 pcs), making it suitable for high-volume production requirements. Both parts satisfy RoHS3 compliance and REACH unaffected status, supporting applications requiring environmental regulatory adherence. Selection between these equivalents should be based on supply chain availability and procurement lead times, as all electrical and mechanical specifications are identical.

Frequently Asked Questions (FAQ)

Q: Are BTH-050-02-L-D-A-TR and BTH-050-02-L-D-A-K-TR directly interchangeable?

A: Yes. Both parts share identical electrical and mechanical specifications, including position count, pitch, row configuration, mounting type, contact finish, and physical dimensions. They are parametric equivalents suitable for direct substitution in surface mount applications.

Q: What determines substitution eligibility for this connector series?

A: Substitution is determined by matching all critical parameters: 100 positions, 0.020" pitch, 2-row configuration, surface mount technology, gold contact finish at 10.0µin thickness, 0.286" height above board, and 8mm mated stacking height. Packaging format and compliance certifications must also align.

Q: Does the packaging format affect connector performance?

A: No. Both parts are supplied in Tape & Reel (TR) format, which is a handling and delivery specification only. The connector performance and electrical characteristics remain identical regardless of packaging method.

Q: Are there compliance differences between these substitute parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating. They are equivalent for applications requiring environmental regulatory certification.

Q: What is the significance of the outer shroud contacts feature?

A: Outer shroud contacts provide mechanical guidance and polarization during mating operations. Both substitute parts incorporate this feature identically, ensuring consistent connector alignment and contact engagement in surface mount assemblies.
