TSW-109-23-F-S Equivalent & Substitute Parts

Part Overview

The TSW-109-23-F-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 9-position, single-row connector operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-plated posts. The part maintains active product status with 945 units in current inventory.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory depletion, or when design requirements permit alternative configurations that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-109-23-F-S is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly
• Connector Type: Header with male pin contacts
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish: Gold mating surface with tin post finish
• Insulation Material: PBT or equivalent thermoplastic
• Operating Temperature Range: Must encompass or exceed -55°C ~ 125°C
• Material Flammability: UL94 V-0 compliance
• RoHS Compliance: ROHS3 or equivalent

The substitute part 4-103185-0 (TE Connectivity AMP Connectors) shares the core pitch, connector type, mounting method, and termination approach. However, this part is a 40-position breakaway header, representing a different position count and configuration than the 9-position TSW-109-23-F-S. Substitution is valid only when the application permits the use of a higher-position-count breakaway connector that can be configured to the required 9-position specification through mechanical separation.

Parameter Comparison

Engineering Selection Recommendations

The TSW-109-23-F-S remains the primary selection for new designs due to its active product status and ROHS3 compliance certification. The part is currently in stock with adequate inventory levels.

The 4-103185-0 substitute carries obsolete product status and lacks RoHS compliance documentation, making it unsuitable for applications requiring regulatory compliance with current environmental standards. Additionally, the operating temperature maximum of 105°C falls below the TSW-109-23-F-S specification of 125°C, and the post contact finish differs (Tin-Lead versus Tin).

Substitution with 4-103185-0 is permissible only in legacy applications where RoHS compliance is not required, operating temperatures remain below 105°C, and the 40-position breakaway configuration can be mechanically adapted to the 9-position requirement through connector separation.

Frequently Asked Questions (FAQ)

Q: Can the 4-103185-0 directly replace the TSW-109-23-F-S in new designs?

A: No. The 4-103185-0 is obsolete and lacks ROHS3 compliance. New designs must use the TSW-109-23-F-S or equivalent active-status parts meeting current regulatory requirements.

Q: What is the primary difference between these connectors?

A: The TSW-109-23-F-S is a fixed 9-position header, while the 4-103185-0 is a 40-position breakaway header. Position count and breakaway capability represent fundamental design differences.

Q: Are the pitch specifications identical?

A: Yes. Both connectors operate at 0.100" (2.54mm) mating pitch, which is a core compatibility requirement.

Q: Does the operating temperature difference affect substitution?

A: Yes. The TSW-109-23-F-S operates to 125°C, while the 4-103185-0 operates to 105°C. Applications requiring operation above 105°C cannot use the substitute part.

Q: What is the significance of the RoHS compliance difference?

A: ROHS3 compliance is mandatory for products sold into regulated markets. The TSW-109-23-F-S meets this requirement; the 4-103185-0 does not. This difference disqualifies the substitute for compliant applications.

Q: Are the contact materials compatible?

A: Both use gold-plated mating surfaces. The TSW-109-23-F-S uses phosphor bronze base material with tin posts, while the 4-103185-0 uses copper alloy with tin-lead posts. These differences are acceptable for electrical continuity but represent material specification variations.

Q: Can the 40-position breakaway connector be used as a 9-position connector?

A: Mechanically, yes, through connector separation. However, this approach introduces assembly complexity and is only appropriate for legacy applications where the substitute's obsolete status and non-compliance issues are acceptable.
