HTSW-112-07-L-S Equivalent & Substitute Parts

Part Overview

The HTSW-112-07-L-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications requiring a 12-position, single-row vertical header with 0.100" (2.54mm) pitch. This connector is classified as an active product and serves board-to-board or cable interconnection applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require component flexibility.

Substitute Part Grouping Explanation

Substitution eligibility for the HTSW-112-07-L-S is determined by the following critical parameters:

Connector Type & Contact Configuration: Header with male pins
Position Count & Row Configuration: 12 positions in a single row
Mating Pitch: 0.100" (2.54mm) spacing
Mounting & Termination: Through-hole solder termination
Fastening Mechanism: Push-pull engagement
Contact Geometry: Square contact shape
Operating Temperature: Minimum -55°C to maximum 125°C
Regulatory Compliance: UL94 V-0 flammability rating and RoHS compliance

The substitute part 68001-112HLF (Amphenol ICC/FCI BERGSTIK® II series) meets all critical substitution criteria. Both parts share identical mating pitch, position count, row configuration, mounting type, termination method, fastening type, contact shape, operating temperature range, and flammability rating. Variations in contact length specifications and insulation material do not preclude substitution when mechanical envelope and electrical performance requirements are satisfied.

Engineering Selection Recommendations

Both the HTSW-112-07-L-S and 68001-112HLF are active products with full regulatory compliance. Selection between these parts should be based on the following factors:

HTSW-112-07-L-S (Samtec): Suitable for applications where the specified contact finish thickness of 10.0µin (0.25µm) and post length of 0.100" (2.54mm) are design requirements. This part maintains ROHS3 compliance and operates across the -55°C to 125°C temperature range.

68001-112HLF (Amphenol ICC/FCI): Suitable for applications where enhanced contact durability through increased gold plating thickness (30.0µin / 0.76µm) is beneficial. The extended operating temperature range (-65°C to 125°C) provides additional thermal margin. The longer post length (0.120" / 3.05mm) may require PCB layout verification for clearance compatibility.

Both parts satisfy UL94 V-0 flammability requirements and RoHS compliance. Mechanical envelope differences (overall contact length variance of 0.020" / 0.51mm) must be evaluated against specific PCB design constraints and mating connector specifications.

Frequently Asked Questions (FAQ)

Q: Can the 68001-112HLF directly replace the HTSW-112-07-L-S in existing designs?

A: Direct replacement is possible when the mechanical envelope variation (0.020" difference in overall contact length) does not conflict with PCB layout or mating connector specifications. The longer post length of the 68001-112HLF (0.120" vs. 0.100") must be verified against PCB thickness and clearance requirements.

Q: What is the significance of the contact finish thickness difference?

A: The HTSW-112-07-L-S specifies 10.0µin (0.25µm) gold plating, while the 68001-112HLF specifies 30.0µin (0.76µm). The thicker plating on the substitute part provides enhanced wear resistance and corrosion protection, particularly beneficial in high-cycle mating applications or harsh environments.

Q: Are both parts suitable for the same operating temperature range?

A: The HTSW-112-07-L-S operates from -55°C to 125°C. The 68001-112HLF extends the lower temperature limit to -65°C, providing additional thermal margin. Both parts support the upper temperature limit of 125°C.

Q: What packaging considerations apply to these parts?

A: Both parts are supplied in bag packaging. Inventory availability differs: HTSW-112-07-L-S has 832 pieces in stock, while 68001-112HLF has 2066 pieces available. Moisture sensitivity levels differ: HTSW-112-07-L-S is not applicable, while 68001-112HLF is rated MSL 1 (Unlimited).

Q: Are both parts RoHS compliant?

A: Yes. The HTSW-112-07-L-S is ROHS3 compliant. The 68001-112HLF is RoHS compliant and additionally carries REACH Unaffected status.
