HTSW-103-07-L-D-LL Equivalent & Substitute Parts

Part Overview

The HTSW-103-07-L-D-LL is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting in 6-position, 2-row configurations with 0.100" (2.54mm) pitch. This connector features kinked pin solder termination, gold-plated mating contacts, and operates across -55°C to 125°C. The part is currently active in production with RoHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative manufacturing sources are required for supply chain resilience, or when design flexibility permits selection from functionally compatible alternatives that meet the same electrical and mechanical requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the HTSW-103-07-L-D-LL is determined by strict alignment of the following parameters:

Connector type (Header)
Contact type (Male Pin)
Mating pitch (0.100" / 2.54mm)
Position count (6 positions)
Row configuration (2 rows)
Row spacing (0.100" / 2.54mm)
Mounting method (Through Hole)
Shrouding status (Unshrouded)
Contact shape (Square)
Fastening mechanism (Push-Pull)
Flammability rating (UL94 V-0)
Moisture sensitivity level (1 / Unlimited)

All substitute parts listed meet these core criteria. Variations in contact finish, contact length specifications, insulation material, and operating temperature ranges are permitted within the substitution set, as these do not affect mechanical or electrical compatibility at the mating interface.

Engineering Selection Recommendations

For applications requiring direct substitution with minimal design impact, the Amphenol ICC (FCI) BERGSTIK® II series parts (67996-106HLF, 67996-206HLF, 67996-406HLF) are preferred. These parts maintain the same 0.100" (2.54mm) pitch, 6-position, 2-row configuration, and operating temperature range of -65°C to 125°C, which encompasses the HTSW-103-07-L-D-LL specification. All three variants are RoHS compliant and currently active in production.

The TE Connectivity AMPMODU Mod II series (5-146254-3, 5-146256-3, 5-146257-3, 5-146261-3) provides additional alternatives with active product status and RoHS compliance. These parts feature identical mating pitch and position count but operate at -65°C to 105°C, which is acceptable for applications not requiring the full -55°C to 125°C range of the primary part.

Parts 104350-3 and 146256-3 carry obsolete product status and RoHS non-compliance, limiting their suitability for new designs or applications with regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the HTSW-103-07-L-D-LL with any of the listed parts without PCB redesign?

A: Substitution is mechanically feasible for all listed parts due to identical mating pitch (0.100" / 2.54mm), position count (6), row configuration (2 rows), and through-hole mounting. However, variations in contact post length and overall contact length may require verification of PCB hole depth and solder pad geometry. The HTSW-103-07-L-D-LL has a contact post length of 0.100" (2.54mm), while most TE Connectivity alternatives specify 0.120" (3.05mm) and Amphenol alternatives range from 0.090" to 0.095" (2.29mm to 2.41mm).

Q: What is the difference between the Amphenol BERGSTIK® II variants (67996-106HLF, 67996-206HLF, 67996-406HLF)?

A: The three variants differ in contact finish specifications. The 67996-106HLF features 30.0µin (0.76µm) gold mating finish, the 67996-206HLF features 15.0µin (0.38µm) gold mating finish, and the 67996-406HLF features 100.0µin (2.54µm) tin mating finish. All three maintain identical mechanical dimensions, pitch, and electrical ratings.

Q: Are the TE Connectivity AMPMODU Mod II parts suitable for high-temperature applications?

A: The TE Connectivity AMPMODU Mod II series (5-146254-3, 5-146256-3, 5-146257-3, 5-146261-3) operate at -65°C to 105°C, which is 20°C lower than the HTSW-103-07-L-D-LL maximum of 125°C. These parts are suitable for applications with maximum operating temperatures up to 105°C. For applications requiring operation at 105°C to 125°C, the Amphenol BERGSTIK® II series or the primary HTSW part are required.

Q: What packaging formats are available for these substitute parts?

A: The HTSW-103-07-L-D-LL is supplied in Bulk packaging. TE Connectivity AMPMODU Mod II parts are supplied in Bulk packaging. Amphenol BERGSTIK® series parts are supplied in Bag packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Which substitute parts maintain RoHS3 compliance matching the primary part?

A: The 5-146254-3 (TE Connectivity) and all Amphenol BERGSTIK® II variants (54102-G0803LF, 67996-106HLF, 67996-206HLF, 67996-406HLF) maintain RoHS3 or RoHS compliance. The 104350-3 and 146256-3 are RoHS non-compliant and unsuitable for applications with RoHS requirements.
