HTSW-109-20-L-S Equivalent & Substitute Parts

Part Overview

The HTSW-109-20-L-S is an active rectangular connector header manufactured by Samtec Inc. This through-hole connector features 9 positions with 0.100" (2.54mm) pitch spacing and is designed for board-to-board or cable applications. The connector utilizes male pin contacts with gold-plated mating surfaces and tin-plated posts, housed in a Liquid Crystal Polymer (LCP) insulation body. Equivalent and substitute parts are identified to support component availability, supply chain flexibility, and design continuity across manufacturing environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTSW-109-20-L-S is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (9)
• Number of rows (1)
• Pitch spacing (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Contact material (Phosphor Bronze)
• Contact finish - mating surface (Gold)
• Contact finish - post (Tin)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)

The TSW-109-20-L-S meets all substitution criteria. Both connectors share identical electrical and mechanical specifications across all critical parameters. The primary difference is the insulation material: HTSW-109-20-L-S uses Liquid Crystal Polymer (LCP), while TSW-109-20-L-S uses Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements and are suitable for the specified operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both HTSW-109-20-L-S and TSW-109-20-L-S are active products with identical electrical and mechanical specifications. Both connectors are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications.

Selection between these parts should be based on:

• Insulation material preference: LCP (HTSW series) or PBT (TSW series)
• Insulation color requirement: Natural (HTSW) or Black (TSW)
• Supply chain availability and lead time
• Moisture sensitivity level requirements: HTSW-109-20-L-S is not applicable for MSL; TSW-109-20-L-S is MSL 1 (Unlimited)

Both parts are suitable for direct substitution in applications requiring 9-position, 2.54mm pitch through-hole header connectors with gold-plated mating contacts.

Frequently Asked Questions (FAQ)

Q: Can TSW-109-20-L-S replace HTSW-109-20-L-S in existing designs?

A: Yes. Both connectors share identical contact geometry, pitch spacing, mating surface finish, and operating temperature specifications. The insulation material differs (LCP versus PBT), but both materials meet UL94 V-0 flammability requirements and support the full operating temperature range of -55°C to 125°C.

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

A: LCP (Liquid Crystal Polymer) and PBT (Polybutylene Terephthalate) are both thermoplastic materials suitable for connector insulation. Both achieve UL94 V-0 flammability ratings. Material selection is typically driven by specific application requirements, environmental conditions, and design preferences. Both materials are compatible with the specified operating temperature range.

Q: Are there any compatibility issues when substituting between HTSW and TSW series?

A: No compatibility issues exist. Both connectors feature identical contact dimensions, pitch spacing, and mating surface specifications. They are mechanically and electrically interchangeable in applications designed for 9-position, 2.54mm pitch through-hole headers.

Q: What does ROHS3 compliance mean for these connectors?

A: ROHS3 compliance indicates that both connectors meet Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials including lead, cadmium, mercury, and certain brominated flame retardants. Both parts are suitable for applications requiring RoHS compliance.

Q: How does moisture sensitivity level affect part selection?

A: HTSW-109-20-L-S has no applicable MSL rating, while TSW-109-20-L-S carries MSL 1 (Unlimited). MSL 1 indicates the part has unlimited shelf life without moisture control requirements. For applications with extended storage or high-humidity environments, TSW-109-20-L-S offers additional flexibility in handling and storage conditions.
