TSW-103-15-S-S Equivalent & Substitute Parts

Part Overview

The TSW-103-15-S-S is an active rectangular connector header manufactured by Samtec Inc. in the TSW series. This through-hole vertical header features 3 positions with 0.100" (2.54mm) pitch spacing and is designed for board-to-board or cable applications. The connector utilizes solder termination with push-pull fastening and operates across -55°C to 125°C. Finding equivalent substitute parts is necessary when the primary part is unavailable, when alternative sourcing is required, or when inventory constraints necessitate compatible alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSW-103-15-S-S is determined by strict alignment of the following critical parameters:

• Connector type classification (Header)
• Contact type (Male Pin)
• Mating pitch (0.100" / 2.54mm)
• Position count (3 positions)
• Row configuration (1 row)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Contact finish on mating surface (Gold)
• Operating temperature range compatibility
• RoHS3 compliance status

The substitute part 5-146277-3 from TE Connectivity AMP Connectors meets these core substitution criteria. Both parts share identical mating pitch, position count, row configuration, mounting type, termination method, fastening type, and contact finish specifications. Both are RoHS3 compliant and operate within acceptable temperature ranges for most applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-103-15-S-S and 5-146277-3 are active products with ROHS3 compliance and UL94 V-0 flammability ratings. Selection between these parts is based on the following engineering considerations:

The TSW-103-15-S-S operates across a wider temperature range (-55°C to 125°C) compared to the 5-146277-3 (-65°C to 105°C). Applications requiring sustained operation above 105°C or below -65°C necessitate the TSW-103-15-S-S.

The 5-146277-3 features a breakaway connector option, which may provide design flexibility for modular applications. The TE Connectivity part also specifies a current rating of 3A, whereas the TSW-103-15-S-S does not provide this specification in the available data.

Physical dimensions differ between the two parts. The TSW-103-15-S-S has a longer overall contact length (0.730" vs 0.533") and greater insulation height (0.100" vs 0.090"), which may affect PCB layout and mating depth considerations.

Both parts maintain identical mating pitch, position count, and core electrical interface specifications, ensuring functional compatibility in standard board-to-board or cable connection applications.

Frequently Asked Questions (FAQ)

Q: Can the 5-146277-3 directly replace the TSW-103-15-S-S in all applications?

A: Direct replacement is possible for applications operating within the overlapping temperature range (-55°C to 105°C) and where the physical dimension differences do not impact PCB layout or connector mating depth. Applications requiring operation above 105°C or below -65°C require the TSW-103-15-S-S.

Q: What are the key differences in physical dimensions between these parts?

A: The TSW-103-15-S-S has an overall contact length of 0.730" (18.54mm) and insulation height of 0.100" (2.54mm), while the 5-146277-3 measures 0.533" (14.65mm) overall contact length with 0.090" (2.29mm) insulation height. These differences may affect PCB routing, connector stack height, and mating interface geometry.

Q: Are both parts RoHS3 compliant?

A: Yes, both the TSW-103-15-S-S and 5-146277-3 are ROHS3 compliant and carry UL94 V-0 flammability ratings.

Q: What is the significance of the breakaway feature on the 5-146277-3?

A: The breakaway feature on the AMPMODU Mod II series allows individual positions to be separated from the connector body, providing design flexibility for modular or reconfigurable applications. The TSW-103-15-S-S does not offer this feature.

Q: Do these connectors have current or voltage ratings specified?

A: The 5-146277-3 specifies a current rating of 3A. The TSW-103-15-S-S does not provide current or voltage rating specifications in the available technical data.

Q: What insulation materials are used in each connector?

A: The TSW-103-15-S-S uses Polybutylene Terephthalate (PBT), while the 5-146277-3 uses Liquid Crystal Polymer (LCP). Both materials are UL94 V-0 rated and suitable for high-reliability applications.
