HTSW-106-25-S-S Equivalent & Substitute Parts

Part Overview

The HTSW-106-25-S-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications requiring board-to-board or cable connections. This unshrouded, 6-position header operates across a wide temperature range and is constructed with phosphor bronze contacts finished in gold for reliable mating surfaces. The part maintains Active product status and is fully stocked, making it a standard component for applications requiring 0.100" (2.54mm) pitch connectivity. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in design and procurement scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTSW-106-25-S-S is determined by strict alignment of the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 6
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Material: Phosphor Bronze
• Contact Finish - Mating: Gold
• Insulation Material: Liquid Crystal Polymer (LCP)
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 78511-106HLF (Amphenol ICC / FCI, BERGSTIK® II series) meets all critical electrical and mechanical parameters required for direct substitution. Both parts share identical pitch, position count, row configuration, mounting methodology, and contact material specifications. The gold-finished phosphor bronze contacts ensure equivalent mating performance and signal integrity. Both components maintain UL94 V-0 flammability compliance and unlimited moisture sensitivity ratings, confirming suitability for equivalent environmental conditions.

Parameter Comparison

Engineering Selection Recommendations

Both the HTSW-106-25-S-S and 78511-106HLF maintain Active product status with full inventory availability, confirming ongoing manufacturing support and supply chain reliability. The HTSW-106-25-S-S carries ROHS3 compliance with REACH Unaffected status, while the 78511-106HLF is RoHS Compliant with REACH Affected designation. Selection between these parts should account for regulatory requirements specific to the end application and target market. The Samtec part offers a wider operating temperature floor at -55°C compared to the Amphenol ICC part at -65°C; applications requiring extended low-temperature performance should reference the specific thermal requirements of the design. Contact post length differs between the two parts (0.210" versus 0.120"), which may influence PCB layout and solder joint geometry; board design should accommodate the selected part's post dimensions. Both parts are suitable for equivalent electrical performance in standard 0.100" pitch header applications.

Frequently Asked Questions (FAQ)

Q: Can the 78511-106HLF directly replace the HTSW-106-25-S-S in existing designs?

A: Yes, the 78511-106HLF meets all critical electrical and mechanical substitution parameters. Both parts share identical pitch (0.100"), position count (6), row configuration (1), contact material (phosphor bronze), and gold mating finish. Mechanical fit and electrical performance are equivalent. However, the contact post length differs (0.210" versus 0.120"), requiring verification that PCB pad layout and solder joint clearances accommodate the substitute part's dimensions.

Q: What are the key differences between these two parts?

A: The primary differences are contact post length (0.210" for HTSW-106-25-S-S versus 0.120" for 78511-106HLF), operating temperature range (-55°C to 125°C versus -65°C to 125°C), insulation color (natural versus black), and regulatory compliance status (ROHS3/REACH Unaffected versus RoHS/REACH Affected). Mating contact dimensions and gold finish specifications are equivalent.

Q: Are there any compliance considerations when substituting these parts?

A: Yes. The HTSW-106-25-S-S is ROHS3 Compliant with REACH Unaffected status, while the 78511-106HLF is RoHS Compliant with REACH Affected status. Applications subject to REACH regulations or requiring ROHS3 certification should confirm that the substitute part meets specific regulatory requirements for the target market and end application.

Q: Does the difference in contact post length affect PCB design?

A: Yes. The HTSW-106-25-S-S has a 0.210" post length, while the 78511-106HLF has a 0.120" post length. PCB pad layout, solder joint clearances, and component placement must accommodate the selected part's post dimensions. Design verification is required to ensure adequate solder fillet formation and mechanical stability.

Q: Which part should be selected for low-temperature applications?

A: The 78511-106HLF supports operation down to -65°C, compared to the HTSW-106-25-S-S at -55°C. For applications requiring extended low-temperature performance below -55°C, the 78511-106HLF is the appropriate selection. Both parts operate to 125°C at the upper temperature limit.
