TSW-124-14-S-D Equivalent & Substitute Parts

Part Overview

The TSW-124-14-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This connector features 48 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, suitable for board-to-board or cable interconnections. The part maintains Active product status with full inventory availability. Substitute parts become necessary when addressing obsolescence concerns, compliance requirements, or specific application constraints that may require alternative connector configurations or electrical ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-124-14-S-D is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match for mechanical compatibility
• Number of Rows: 2 — determines physical layout and spacing
• Contact Type: Male Pin — defines mating interface
• Mounting Type: Through Hole — establishes PCB assembly method
• Termination: Solder — specifies connection method
• Connector Type: Header — functional classification

The identified substitute part 4-102973-0 (TE Connectivity AMP Connectors) shares the core pitch, row configuration, contact type, mounting method, and termination approach. However, this substitute differs in position count (80 vs. 48), product status (Obsolete vs. Active), and compliance certifications, requiring careful evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TSW-124-14-S-D maintains Active product status with ROHS3 compliance, making it the preferred selection for new designs and applications requiring regulatory adherence. The substitute part 4-102973-0 carries Obsolete status and RoHS non-compliance, limiting its applicability to legacy system maintenance or applications where regulatory compliance is not mandated.

Selection between these parts must account for:

• Position count requirements: The main part provides 48 positions; the substitute provides 80 positions. PCB layout and connector footprint must accommodate the selected configuration.
• Temperature operating range: The main part operates -55°C to 125°C; the substitute operates -65°C to 105°C. Application thermal requirements determine suitability.
• Compliance requirements: ROHS3 compliance of the main part satisfies modern regulatory frameworks; RoHS non-compliance of the substitute restricts use to non-regulated applications.
• Product lifecycle: Active status of the main part ensures long-term availability and supply chain stability; Obsolete status of the substitute introduces supply risk.

Frequently Asked Questions (FAQ)

Q: Can the 4-102973-0 substitute directly replace the TSW-124-14-S-D in existing designs?

A: Direct replacement is not recommended. The substitute has 80 positions versus 48 positions in the main part, requiring PCB layout modification. Additionally, the substitute's Obsolete status and RoHS non-compliance create supply and regulatory concerns.

Q: What are the critical matching parameters for this connector category?

A: Pitch spacing (0.100" / 2.54mm), number of rows (2), contact type (Male Pin), mounting method (Through Hole), and termination type (Solder) must match for mechanical and electrical compatibility.

Q: Does the operating temperature difference affect substitution feasibility?

A: The main part operates -55°C to 125°C while the substitute operates -65°C to 105°C. Applications requiring operation above 105°C cannot use the substitute. Applications operating below -55°C cannot use the main part.

Q: What compliance implications exist for using the 4-102973-0 substitute?

A: The substitute is RoHS non-compliant, making it unsuitable for applications subject to RoHS regulations. The main part's ROHS3 compliance satisfies current regulatory requirements.

Q: Are there packaging or inventory considerations?

A: The main part (TSW-124-14-S-D) has 828 pieces in stock; the substitute (4-102973-0) has 1761 pieces in stock. However, the substitute's Obsolete status indicates declining availability over time.
