HTSW-148-10-G-D Equivalent & Substitute Parts

Part Overview

The HTSW-148-10-G-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 96-position, 2-row connector operates across -55°C to 125°C and features gold-plated phosphor bronze contacts with liquid crystal polymer (LCP) insulation. The part maintains active product status with ROHS3 compliance and UL94 V-0 flammability rating. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific material or performance characteristics are required for particular applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTSW-148-10-G-D is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (96)
• Number of rows (2)
• Pitch - mating (0.100" / 2.54mm)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Contact material (Phosphor Bronze)
• Contact finish - mating (Gold)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• RoHS compliance (ROHS3)

The TSW-148-10-G-D meets all critical substitution criteria. Differences exist only in insulation material (PBT versus LCP) and insulation color, which do not affect electrical or mechanical compatibility for standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HTSW-148-10-G-D and TSW-148-10-G-D are active products with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on insulation material requirements. The HTSW series uses liquid crystal polymer (LCP) insulation, while the TSW series uses polybutylene terephthalate (PBT) insulation. Both materials support the full operating temperature range of -55°C to 125°C and maintain identical electrical and mechanical specifications for connector pitch, contact geometry, and gold plating thickness. Part selection should be determined by application-specific insulation material requirements and PCB assembly process compatibility.

Frequently Asked Questions (FAQ)

Q: Are HTSW-148-10-G-D and TSW-148-10-G-D mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), contact geometry, mounting type (through hole), and overall dimensions. They are mechanically interchangeable in board-to-board applications.

Q: What is the difference between LCP and PBT insulation materials?

A: The HTSW-148-10-G-D uses liquid crystal polymer (LCP) insulation, while the TSW-148-10-G-D uses polybutylene terephthalate (PBT) insulation. Both materials meet UL94 V-0 flammability requirements and support the operating temperature range of -55°C to 125°C. Material selection depends on specific application requirements and manufacturing process compatibility.

Q: Do both parts have the same contact finish specifications?

A: Yes. Both parts feature gold-plated phosphor bronze contacts with identical finish thickness: 10.0µin (0.25µm) on mating surfaces and 3.00µin (0.076µm) on post surfaces.

Q: Are both parts RoHS compliant?

A: Yes. Both HTSW-148-10-G-D and TSW-148-10-G-D are ROHS3 compliant and carry EAR99 export classification.

Q: What is the operating temperature range for these connectors?

A: Both connectors operate across -55°C to 125°C, supporting a wide range of industrial and commercial applications.

Q: Can these connectors be used in high-reliability applications?

A: Both parts meet UL94 V-0 flammability standards and maintain active product status with full compliance certifications. Suitability for specific high-reliability applications depends on application-specific requirements beyond the provided specifications.
