TSW-130-14-S-D Equivalent & Substitute Parts

Part Overview

The TSW-130-14-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This vertical header features 60 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. The connector is currently in active production status with gold-plated mating contacts and tin-plated posts, suitable for applications requiring reliable solder termination and push-pull fastening.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements necessitate alternative connector configurations with compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-130-14-S-D is determined by the following critical parameters:

Primary Compatibility Criteria:

• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Connector Style: Board to Board or Cable

Secondary Compatibility Criteria:

• Number of Positions: 60 (exact match required for direct substitution)
• Number of Rows: 2 (exact match required)
• Contact Finish - Mating: Gold
• Insulation Material: PBT or equivalent thermoplastic
• Operating Temperature Range: Must encompass or match -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0

The substitute part 4-102977-0 (TE Connectivity AMP Connectors AMPMODU Mod II series) shares the core mating pitch, row configuration, contact type, and through-hole solder termination. However, this part differs in position count (80 vs. 60), insulation height, contact length specifications, and operating temperature range, requiring engineering evaluation for specific application compatibility.

Parameter Comparison

Engineering Selection Recommendations

TSW-130-14-S-D (Primary Selection): The TSW-130-14-S-D remains the preferred component for new designs and ongoing production. This part maintains active product status, ROHS3 compliance, and operates across the extended temperature range of -55°C to 125°C. The phosphor bronze contact material with gold plating and tin post finish provides reliable electrical performance for solder-terminated applications.

4-102977-0 (Substitute Consideration): The 4-102977-0 is classified as obsolete and carries "Not applicable" RoHS status, making it unsuitable for applications requiring regulatory compliance with current RoHS directives. The reduced operating temperature upper limit of 105°C (versus 125°C) and different insulation height (0.090" vs. 0.100") present mechanical and thermal constraints. The increased position count (80 vs. 60) requires board layout modification. This part should only be considered for legacy system maintenance where original specifications are non-negotiable and regulatory compliance is not required.

Frequently Asked Questions (FAQ)

Q: Can the 4-102977-0 be used as a direct drop-in replacement for the TSW-130-14-S-D?

A: No. While both connectors share the same 0.100" (2.54mm) mating pitch and row spacing, the 4-102977-0 has 80 positions compared to the TSW-130-14-S-D's 60 positions. This difference requires PCB layout modification and cannot be accommodated as a direct substitution without design changes.

Q: What are the key electrical compatibility factors between these connectors?

A: Both connectors feature gold-plated mating contacts and tin-based post finishes suitable for solder termination. The primary electrical difference is the contact material: phosphor bronze in the TSW-130-14-S-D versus copper alloy in the 4-102977-0. Both materials provide adequate conductivity for standard through-hole applications.

Q: Are there temperature rating implications for substitution?

A: Yes. The TSW-130-14-S-D operates from -55°C to 125°C, while the 4-102977-0 operates from -65°C to 105°C. Applications requiring operation above 105°C cannot use the 4-102977-0. The TSW-130-14-S-D's extended upper temperature limit makes it suitable for a broader range of thermal environments.

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

A: The TSW-130-14-S-D is ROHS3 compliant, meeting current regulatory requirements for restricted substances in electrical and electronic equipment. The 4-102977-0 carries "Not applicable" RoHS status due to its obsolete classification. For applications subject to RoHS directives or customer compliance requirements, only the TSW-130-14-S-D is acceptable.

Q: How do the insulation height differences affect mechanical compatibility?

A: The TSW-130-14-S-D has an insulation height of 0.100" (2.54mm), while the 4-102977-0 measures 0.090" (2.29mm). This 0.010" difference affects mating connector alignment and board-to-board spacing. Designs must account for this variation to ensure proper mechanical fit and electrical contact.

Q: What packaging considerations apply to these connectors?

A: Both connectors are supplied in bulk packaging. The TSW-130-14-S-D is currently in stock with 733 pieces available. The 4-102977-0, being obsolete, has limited availability (773 pieces noted in inventory). For production quantities, the TSW-130-14-S-D offers superior supply chain reliability.
