TSW-107-23-F-S Equivalent & Substitute Parts

Part Overview

The TSW-107-23-F-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 7-position, single-row header operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-plated posts. The connector is classified as Active product status and complies with ROHS3 standards with UL94 V-0 flammability rating.

Substitute parts may be required due to inventory constraints, design revisions, or application-specific requirements where alternative connector configurations meet the electrical and mechanical specifications of the original design.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-107-23-F-S is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Contact Shape: Square
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin or equivalent
• Insulation Material: PBT or equivalent thermoplastic
• Operating Temperature Range: Minimum -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: ROHS3 or equivalent

The substitute part 4-103185-0 (TE Connectivity AMP Connectors) shares the core electrical and mechanical characteristics required for functional equivalence, including identical mating pitch, contact type, mounting method, and termination approach. However, differences in position count, insulation height, contact post length, and product status must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TSW-107-23-F-S is the preferred selection for new designs due to its Active product status and ROHS3 compliance. This ensures long-term availability and regulatory alignment with current environmental standards.

The substitute part 4-103185-0 shares critical electrical and mechanical compatibility parameters, including mating pitch, contact configuration, and flammability rating. However, this part carries Obsolete product status, indicating discontinued manufacturing and potential supply constraints. Selection of this substitute should be limited to legacy system maintenance or applications where existing inventory is available.

Key considerations for substitution:

• The 4-103185-0 features 40 positions versus 7 positions in the TSW-107-23-F-S, requiring mechanical accommodation in the PCB layout and connector housing.
• Operating temperature range differs: TSW-107-23-F-S supports -55°C ~ 125°C, while 4-103185-0 supports -65°C ~ 105°C. Applications requiring the full upper temperature range of the Samtec part cannot use the TE Connectivity substitute.
• Insulation height variation (0.100" versus 0.090") may affect board-to-board spacing and mating clearances.
• Contact post length differs by 0.005" (0.13mm), which may impact solder joint formation and PCB trace routing.
• RoHS compliance status differs; the Samtec part is ROHS3 compliant while the TE Connectivity part is not applicable.

Frequently Asked Questions (FAQ)

Q: Can the 4-103185-0 be used as a direct replacement for the TSW-107-23-F-S?

A: The 4-103185-0 shares the same mating pitch (0.100"), contact type (male pin), mounting method (through hole), and termination (solder). However, the 40-position configuration requires different PCB layout and connector housing design compared to the 7-position TSW-107-23-F-S. Direct pin-for-pin substitution is not possible without mechanical redesign.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by mating pitch (0.100" / 2.54mm), contact type (male pin), mounting type (through hole), termination method (solder), contact shape (square), contact finish (gold mating surface), insulation material (thermoplastic), flammability rating (UL94 V-0), and operating temperature range requirements.

Q: Why is the TSW-107-23-F-S preferred over the 4-103185-0?

A: The TSW-107-23-F-S maintains Active product status, ensuring continued manufacturing and supply availability. It is ROHS3 compliant, meeting current environmental regulations. The 4-103185-0 is classified as Obsolete, indicating discontinued production and potential supply discontinuation.

Q: Are there temperature range limitations when using the 4-103185-0 substitute?

A: Yes. The TSW-107-23-F-S operates from -55°C to 125°C, while the 4-103185-0 operates from -65°C to 105°C. Applications requiring operation above 105°C cannot use the TE Connectivity substitute.

Q: How do the insulation height differences affect compatibility?

A: The TSW-107-23-F-S has an insulation height of 0.100" (2.54mm), while the 4-103185-0 has 0.090" (2.29mm). This 0.010" (0.25mm) difference may affect board-to-board spacing, mating clearances, and connector housing fit. PCB layout verification is required before substitution.

Q: What is the significance of the contact post length difference?

A: The TSW-107-23-F-S has a contact post length of 0.115" (2.92mm), while the 4-103185-0 has 0.120" (3.05mm). This 0.005" (0.13mm) difference may impact solder joint formation, PCB trace routing, and through-hole pad design. Solder reflow profile validation is recommended.

Q: Does the RoHS compliance difference affect substitution decisions?

A: The TSW-107-23-F-S is ROHS3 compliant, meeting current environmental regulations for new designs and manufacturing. The 4-103185-0 has "Not applicable" RoHS status due to its Obsolete classification. For applications subject to RoHS requirements, the Samtec part is the only compliant option.
