HTSW-126-22-G-D Equivalent & Substitute Parts

Part Overview

The HTSW-126-22-G-D is an active rectangular connector header manufactured by Samtec Inc. This through-hole connector features 52 positions arranged in 2 rows with 0.100" (2.54mm) pitch, designed for board-to-board or cable applications. The connector utilizes solder termination with push-pull fastening and is constructed with phosphor bronze contacts finished in gold. With 824 units in current inventory, this part remains actively supported for new designs and production applications.

Alternative models become necessary when design requirements specify different insulation materials, color specifications, or when inventory constraints require sourcing from equivalent product lines within the same manufacturer's portfolio.

Key Parameters

Substitute Part Grouping Explanation

Substitution between the HTSW-126-22-G-D and TSW-126-22-G-D is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility:

• Contact type, material, and finish specifications (phosphor bronze with gold plating)
• Pitch and row spacing (0.100" / 2.54mm)
• Operating temperature range (-55°C ~ 125°C)
• Flammability rating (UL94 V-0)
• RoHS3 compliance

Mechanical Compatibility:

• Number of positions and rows (52 positions, 2 rows)
• Mounting type (through hole)
• Termination method (solder)
• Contact length specifications (mating: 0.230", post: 0.300", overall: 0.630")
• Insulation height (0.100")

Allowable Variations:

• Insulation material: Liquid Crystal Polymer (LCP) vs. Polybutylene Terephthalate (PBT)
• Insulation color: Natural vs. Black
• Moisture Sensitivity Level: Not Applicable vs. 1 (Unlimited)

These variations do not affect functional interchangeability in standard board-to-board connector applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HTSW-126-22-G-D and TSW-126-22-G-D are active products from Samtec Inc. with identical electrical and mechanical specifications for connector interface functionality. Selection between these parts should be based on the following criteria:

HTSW-126-22-G-D Selection:

• Applications requiring Liquid Crystal Polymer (LCP) insulation material
• Designs specifying natural-colored connector bodies
• Moisture-sensitive applications where MSL classification is critical

TSW-126-22-G-D Selection:

• Applications requiring Polybutylene Terephthalate (PBT) insulation material
• Designs specifying black-colored connector bodies
• Standard industrial applications with unlimited moisture sensitivity level

Both parts maintain ROHS3 compliance and UL94 V-0 flammability ratings. Current inventory levels support production requirements for either selection.

Frequently Asked Questions (FAQ)

Q: Are HTSW-126-22-G-D and TSW-126-22-G-D electrically interchangeable?

A: Yes. Both connectors share identical electrical specifications including contact material (phosphor bronze), contact finish (gold plating), pitch (0.100"), number of positions (52), operating temperature range (-55°C ~ 125°C), and flammability rating (UL94 V-0).

Q: What is the primary difference between these two connector models?

A: The primary differences are insulation material (LCP vs. PBT), insulation color (natural vs. black), and moisture sensitivity level classification. These differences do not affect electrical or mechanical interface compatibility.

Q: Can I substitute TSW-126-22-G-D for HTSW-126-22-G-D in an existing design?

A: Substitution is mechanically and electrically compatible. However, verify that your design does not have specific requirements for insulation material type or color specification before implementing the change.

Q: Are both parts RoHS compliant?

A: Yes. Both HTSW-126-22-G-D and TSW-126-22-G-D are ROHS3 compliant.

Q: What does Moisture Sensitivity Level (MSL) mean for these connectors?

A: MSL indicates the connector's sensitivity to moisture during storage and handling. HTSW-126-22-G-D is classified as Not Applicable, while TSW-126-22-G-D is classified as MSL 1 (Unlimited), meaning it has no moisture sensitivity restrictions.

Q: Do these connectors require different PCB footprints?

A: No. Both connectors maintain identical mechanical dimensions, pitch, and mounting specifications, allowing use of the same PCB footprint.

Q: Which connector should I select for new designs?

A: Selection depends on your specific insulation material and color requirements. Both parts are active products with current inventory support. Consult your design specifications for material and color constraints.
