TSW-103-26-F-S Equivalent & Substitute Parts

Part Overview

The TSW-103-26-F-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This unshrouded, vertically-oriented header features 3 positions with 0.100" (2.54mm) pitch spacing and male pin contacts. The connector is actively produced and RoHS3 compliant, making it suitable for modern electronic assemblies requiring board-to-board or cable interconnection.

Equivalent and substitute parts become necessary when addressing supply chain constraints, design revisions requiring different contact finishes or post lengths, or when transitioning between active and obsolete product lines while maintaining electrical and mechanical compatibility.

Number of Rows: 1
Connector Type: Header
Contact Type: Male Pin
Mounting Type: Through Hole
Termination: Solder
Fastening Type: Push-Pull
Contact Shape: Square
Material Flammability Rating: UL94 V-0

Secondary Compatibility Parameters (Allowable Variation):

Contact Length - Mating: 0.230" ± tolerance
Contact Length - Post: 0.095" to 0.126"
Overall Contact Length: 0.395" to 0.456"
Insulation Height: 0.090" to 0.100"
Contact Finish - Mating: Gold or Tin

Engineering Selection Recommendations

Primary Substitute - 68000-203HLF (Amphenol ICC)

The 68000-203HLF is the most direct substitute for the TSW-103-26-F-S. Both parts share identical pitch, position count, contact geometry, and flammability rating. The 68000-203HLF is actively produced, RoHS3 compliant, and available in high volume (1,482 units in stock). The gold contact finish on the mating surface matches the TSW-103-26-F-S specification. Minor differences in contact post length (0.095" vs. 0.126") fall within acceptable PCB mounting tolerances and do not affect electrical performance.

Secondary Substitute - 0022284030 (Molex)

The Molex 0022284030 offers full electrical and mechanical compatibility with identical pitch and position specifications. This part is actively produced and RoHS3 compliant with substantial inventory availability (14,125 units). The primary distinction is the tin contact finish on the mating surface and slightly reduced insulation height (0.090" vs. 0.100"). These variations remain within acceptable substitution parameters for standard through-hole applications.

Alternative Substitutes - 68001 Series (Amphenol ICC)

The 68001-103HLF, 68001-203HLF, and 68001-403HLF represent active alternatives with extended contact post lengths (0.120" vs. 0.126"). These parts maintain all primary compatibility criteria and are RoHS compliant. Selection among these variants depends on specific PCB thickness and assembly requirements. All three are actively produced with adequate inventory levels.

Avoid - 68000-103 and 68000-403H

These parts carry obsolete product status and should not be selected for new designs or long-term supply planning, despite technical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute the TSW-103-26-F-S with the Molex 0022284030?

A: Yes. Both connectors meet all primary compatibility criteria: 0.100" pitch, 3 positions, 1 row, through-hole mounting, solder termination, and push-pull fastening. The tin contact finish on the Molex part differs from the gold finish on the Samtec part, but both provide adequate electrical conductivity for standard applications. The slightly reduced insulation height (0.090" vs. 0.100") does not affect mechanical fit on standard PCBs.

Q: What is the difference between the 68000-203HLF and 68001-203HLF?

A: Both parts are Amphenol ICC BERGSTIK® II headers with identical pitch, position count, and contact geometry. The primary difference is contact post length: 68000-203HLF has 0.095" posts while 68001-203HLF has 0.120" posts. Selection depends on PCB thickness and solder joint requirements. For standard 1.6mm PCBs, either part is acceptable.

Q: Are there any compliance differences between substitute parts?

A: The TSW-103-26-F-S is ROHS3 compliant. Most active substitutes (0022284030, 68000-203HLF, 68001-103HLF, 68001-203HLF, 68001-403HLF) are either ROHS3 or RoHS compliant. All listed active parts meet UL94 V-0 flammability requirements and have MSL 1 (Unlimited) moisture sensitivity ratings. Obsolete parts (68000-103, 68000-403H) are RoHS non-compliant and should not be used in new designs.

Q: Does contact finish affect interchangeability?

A: Contact finish (gold vs. tin) does not affect electrical interchangeability for standard signal and low-current applications. Gold finishes provide superior corrosion resistance and are preferred for high-reliability applications. Tin finishes are acceptable for general-purpose applications and offer cost advantages. Both finishes are suitable for push-pull mated connections.

Q: What packaging options are available?

A: The TSW-103-26-F-S is supplied in bulk packaging. Substitute parts are available in both bulk and bag packaging. Bag packaging (indicated by "HLF" suffix in Amphenol part numbers) provides smaller quantity units suitable for prototyping and low-volume production. Bulk packaging is preferred for high-volume manufacturing.

Q: Can I use 68000-403HLF as a substitute?

A: Yes. The 68000-403HLF meets all primary compatibility criteria and is actively produced with ROHS3 compliance. The tin contact finish and 0.095" post length are acceptable variations. This part is available in high volume (5,200 units in stock) and represents a cost-effective alternative.
