Key Parameters

Substitute Part Grouping Explanation

The HTSW-109-18-G-D qualifies as a substitute for the TSW-109-18-G-D based on the following critical parameters:

Matching Parameters:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 18
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Termination: Solder
• Contact length - mating: 0.720" (18.29mm)
• Contact length - post: 0.110" (2.79mm)
• Overall contact length: 0.930" (23.62mm)
• Insulation height: 0.100" (2.54mm)
• Contact shape: Square
• Contact finish - mating: Gold
• Contact material: Phosphor Bronze
• Operating temperature: -55°C ~ 125°C
• Material flammability rating: UL94 V-0
• RoHS status: ROHS3 Compliant

Differing Parameters:

• Insulation material: PBT (main part) vs. LCP (substitute)
• Insulation color: Black (main part) vs. Natural (substitute)
• Moisture sensitivity level: 1 (main part) vs. Not Applicable (substitute)

The substitute part maintains functional and mechanical compatibility through identical contact geometry, pitch spacing, and electrical characteristics. The insulation material difference (PBT to LCP) does not affect mating compatibility or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both TSW-109-18-G-D and HTSW-109-18-G-D are active production parts from Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability ratings. Selection between these parts is based on insulation material requirements and availability:

TSW-109-18-G-D is specified when PBT insulation material is required. This part carries MSL 1 (Unlimited) moisture sensitivity rating and is available with 930 units in current inventory.

HTSW-109-18-G-D is specified when LCP insulation material is acceptable or preferred. This part carries MSL Not Applicable rating and is available with 1079 units in current inventory. LCP insulation provides enhanced dimensional stability and chemical resistance compared to PBT.

Both parts maintain identical electrical and mechanical interface characteristics, including contact geometry, pitch spacing, mating contact length, and operating temperature range. The choice between them does not affect PCB layout, mating connector compatibility, or electrical performance.

Frequently Asked Questions (FAQ)

Q: Can HTSW-109-18-G-D replace TSW-109-18-G-D in existing designs?

A: Yes. Both parts share identical contact geometry, pitch spacing (0.100"), number of positions (18), and mating contact length (0.720"). The primary difference is insulation material (PBT vs. LCP). If the original design does not specify PBT as a requirement, HTSW-109-18-G-D is mechanically and electrically compatible.

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

A: PBT (Polybutylene Terephthalate) and LCP (Liquid Crystal Polymer) are both thermoplastic materials with UL94 V-0 flammability ratings. LCP offers superior dimensional stability and chemical resistance. Both materials are suitable for the operating temperature range of -55°C to 125°C specified for these connectors.

Q: Are the contact finishes identical between these parts?

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

Q: What is the significance of the MSL rating difference?

A: TSW-109-18-G-D carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. HTSW-109-18-G-D carries MSL Not Applicable, indicating the LCP material does not require moisture sensitivity level classification. Both parts are suitable for standard warehouse and assembly environments.

Q: Do these connectors require any special handling or storage conditions?

A: Both parts are ROHS3 compliant and carry standard EAR99 export classification. Standard component storage conditions (controlled temperature and humidity) are appropriate for both parts.
