HTSW-148-29-G-D Equivalent & Substitute Parts

Part Overview

The HTSW-148-29-G-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 96-position, 2-row connector operates across the industrial temperature range of -55°C to 125°C and is classified as Active product status. The connector uses 0.100" (2.54mm) pitch spacing with gold-plated phosphor bronze contacts and liquid crystal polymer (LCP) insulation. Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and sourcing options while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the HTSW-148-29-G-D are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Identical number of positions (96)
Identical number of rows (2)
Identical pitch spacing (0.100" / 2.54mm)
Identical row spacing (0.100" / 2.54mm)
Identical contact type (Male Pin)
Identical mounting type (Through Hole)
Identical termination method (Solder)
Identical operating temperature range (-55°C ~ 125°C)
Identical material flammability rating (UL94 V-0)
Identical RoHS compliance status (ROHS3 Compliant)

The TSW-148-29-G-D meets all these criteria and is classified as a direct substitute. Variations in insulation material (LCP versus PBT) and insulation color do not affect electrical or mechanical compatibility for this connector category.

Engineering Selection Recommendations

Both the HTSW-148-29-G-D and TSW-148-29-G-D are Active product status connectors manufactured by Samtec Inc. and maintain full ROHS3 compliance. Both connectors satisfy UL94 V-0 material flammability requirements and operate across identical temperature ranges. Selection between these parts should be based on:

Inventory availability and lead time requirements
Insulation material preference (LCP in HTSW series versus PBT in TSW series)
Specific application environmental conditions
PCB layout and mechanical space constraints
Existing design documentation and qualification history

Both parts are electrically and mechanically interchangeable for applications requiring 96-position, 2.54mm pitch through-hole header connectors.

Frequently Asked Questions (FAQ)

Q: Are the HTSW-148-29-G-D and TSW-148-29-G-D fully interchangeable?

A: Yes. Both connectors share identical electrical and mechanical specifications including pitch spacing, contact configuration, operating temperature range, and contact materials. The primary difference is insulation material composition (LCP versus PBT), which does not affect compatibility for standard board-to-board or cable applications.

Q: What is the significance of the insulation material difference between LCP and PBT?

A: Liquid Crystal Polymer (LCP) and Polybutylene Terephthalate (PBT) are both UL94 V-0 rated materials suitable for high-reliability applications. LCP offers superior dimensional stability and lower moisture absorption, while PBT provides established performance in standard industrial environments. Selection depends on specific application requirements.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, provided the original design does not specify material-dependent performance criteria. Both connectors maintain identical pitch, contact geometry, and electrical ratings. Design documentation should be reviewed to confirm no material-specific requirements exist.

Q: What is the through-hole mounting requirement for these connectors?

A: Both connectors are designed for solder termination through printed circuit board holes. The post length of 0.910" (23.11mm) accommodates standard PCB thicknesses with adequate solder joint formation. Hole diameter and spacing must conform to 0.100" (2.54mm) pitch specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the HTSW-148-29-G-D and TSW-148-29-G-D are ROHS3 compliant, meeting all current regulatory requirements for restricted substances in electrical and electronic equipment.
