TSW-112-23-L-S Equivalent & Substitute Parts

Part Overview

The TSW-112-23-L-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 12-position, single-row connector operates at 0.100" (2.54mm) pitch and features unshrouded male pin contacts with gold-plated mating surfaces and tin-plated posts. The connector is classified as Active product status and complies with ROHS3 and REACH requirements. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in board-to-board or cable connection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-112-23-L-S is determined by strict alignment of the following critical parameters:

• Connector Type: Header configuration
• Contact Type: Male Pin
• Number of Positions: 12
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Insulation Material: Polybutylene Terephthalate (PBT) or equivalent dielectric polymer
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The Molex 0022284123 meets all critical substitution criteria. Minor variations in contact length, insulation height, and contact finish thickness remain within acceptable tolerance ranges for board-to-board and cable connection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-112-23-L-S and the Molex 0022284123 are Active product status connectors with ROHS3 compliance and REACH unaffected status, qualifying them for equivalent use in applications requiring regulatory adherence.

The TSW-112-23-L-S features PBT insulation material, while the Molex 0022284123 uses glass-filled polyamide. Both materials achieve UL94 V-0 flammability rating. The Molex part includes breakaway functionality, providing additional design flexibility.

Contact length and insulation height differences between the two parts are minor. The Molex 0022284123 exhibits slightly longer mating contact length (0.240" vs. 0.230") and post length (0.125" vs. 0.115"), with reduced insulation height (0.090" vs. 0.100"). These dimensional variations remain within acceptable ranges for standard board-to-board and cable connection applications.

Contact finish thickness on the Molex part is thicker on the mating surface (15.0µin vs. 10.0µin), providing enhanced durability in high-cycle mating environments. Post finish thickness is specified for the Molex part (100.0µin) but not provided for the Samtec part.

Selection between these parts should be based on specific application requirements, including mechanical fit constraints, mating cycle expectations, and material compatibility with the target application environment.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022284123 directly replace the TSW-112-23-L-S in existing designs?

A: The Molex 0022284123 is electrically and mechanically compatible for board-to-board and cable connection applications. Minor dimensional differences in contact length and insulation height exist but remain within acceptable tolerance ranges for standard connector applications. Physical fit verification in the specific application is necessary to confirm compatibility.

Q: What is the significance of the breakaway feature on the Molex part?

A: The breakaway feature on the Molex 0022284123 allows individual positions to be separated from the connector body after assembly. The TSW-112-23-L-S does not include this feature. This difference does not affect electrical or mechanical compatibility in applications where breakaway functionality is not required.

Q: How do the insulation materials differ between these connectors?

A: The TSW-112-23-L-S uses Polybutylene Terephthalate (PBT), while the Molex 0022284123 uses glass-filled Polyamide (PA/Nylon). Both materials achieve UL94 V-0 flammability rating. Material selection should be evaluated based on specific environmental exposure, chemical compatibility, and thermal cycling requirements of the target application.

Q: Are there differences in contact durability between these parts?

A: The Molex 0022284123 features thicker gold plating on mating contacts (15.0µin vs. 10.0µin), which may provide enhanced durability in high-cycle mating environments. The TSW-112-23-L-S contact finish thickness is specified at 10.0µin. For applications with frequent mating cycles, the thicker finish on the Molex part may offer extended contact life.

Q: Do both connectors meet the same regulatory requirements?

A: Both the TSW-112-23-L-S and Molex 0022284123 are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory standards for electronic component use in regulated markets.

Q: What is the operating temperature range for the Molex 0022284123?

A: The operating temperature range for the Molex 0022284123 is not specified in the provided data. The TSW-112-23-L-S operates from -55°C to 125°C. For applications requiring confirmed temperature specifications, contact the manufacturer directly.
