TSW-132-14-S-D Equivalent & Substitute Parts

Part Overview

The TSW-132-14-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 64-position, 2-row connector operates across a wide temperature range of -55°C to 125°C and features gold-plated mating contacts with tin-plated posts. The part maintains Active product status with full RoHS3 compliance and MSL Level 1 rating, indicating broad availability and suitability for modern electronic assemblies.

Substitute parts become necessary when the primary part experiences supply constraints, obsolescence, or when design requirements permit alternative connector configurations that maintain functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-132-14-S-D is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for PCB footprint compatibility
• Number of Rows: 2 — maintains board-to-board spacing requirements
• Mounting Type: Through Hole — ensures assembly process compatibility
• Termination: Solder — required for permanent board attachment
• Contact Type: Male Pin — functional requirement for mating interface
• Contact Finish - Mating: Gold — electrical performance and corrosion resistance
• Insulation Material: PBT or equivalent thermoplastic — mechanical and thermal stability
• Operating Temperature Range: Must encompass or equal -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0 — safety compliance requirement

The substitute part 4-102977-0 (TE Connectivity AMP Connectors AMPMODU Mod II series) shares the core mating pitch, row configuration, through-hole mounting, solder termination, and gold-plated mating contacts. However, differences in position count (80 vs. 64), insulation height, contact length specifications, and operating temperature range must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TSW-132-14-S-D maintains Active product status with full RoHS3 compliance, making it the preferred choice for new designs and applications requiring regulatory compliance with modern environmental standards. Current inventory of 1099 pieces supports immediate availability.

The 4-102977-0 substitute carries Obsolete product status and lacks RoHS3 compliance designation, indicating limited future availability and potential regulatory restrictions in certain markets. This part is suitable only for legacy system maintenance or applications where RoHS compliance is not required.

Selection between these parts must account for:

• Position count requirements: The 64-position TSW-132-14-S-D differs from the 80-position 4-102977-0, requiring PCB footprint verification
• Operating temperature ceiling: The TSW-132-14-S-D supports 125°C maximum versus 105°C for the substitute, affecting thermal margin calculations
• Contact post length: The 4-102977-0 provides 0.125" (3.18mm) versus 0.110" (2.79mm) for the main part, impacting PCB trace routing and assembly clearances
• Insulation height variance: 0.100" (2.54mm) versus 0.090" (2.29mm) affects board-to-board spacing in stacked configurations
• Regulatory compliance: RoHS3 status is mandatory for applications subject to EU or equivalent environmental regulations

Frequently Asked Questions (FAQ)

Q: Can the 4-102977-0 be used as a direct replacement for the TSW-132-14-S-D?

A: Direct replacement is not possible due to position count mismatch (80 vs. 64 positions). PCB footprint redesign would be required. Additionally, the substitute's Obsolete status and lack of RoHS3 compliance present supply and regulatory risks.

Q: What are the critical compatibility factors between these connectors?

A: Both connectors share 0.100" (2.54mm) mating pitch, 2-row configuration, through-hole solder termination, and gold-plated mating contacts. However, differences in position count, insulation height, contact post length, and operating temperature range require application-specific evaluation.

Q: Does the contact post length difference affect assembly?

A: Yes. The 4-102977-0 provides 0.125" (3.18mm) post length versus 0.110" (2.79mm) for the TSW-132-14-S-D. This 0.015" (0.38mm) difference impacts solder joint formation, PCB trace routing, and component clearance calculations in high-density layouts.

Q: Are there temperature rating implications for application selection?

A: The TSW-132-14-S-D supports -55°C to 125°C operation, while the 4-102977-0 is rated -65°C to 105°C. Applications requiring sustained operation above 105°C or with thermal cycling to 125°C must use the TSW-132-14-S-D.

Q: What is the significance of the RoHS3 compliance difference?

A: RoHS3 compliance is mandatory for products sold into EU markets and many other regulated regions. The TSW-132-14-S-D's ROHS3 Compliant status ensures regulatory acceptance, while the 4-102977-0's "Not applicable" designation indicates it predates or falls outside RoHS requirements, limiting its use in compliant supply chains.

Q: How do the insulation materials compare?

A: The TSW-132-14-S-D uses Polybutylene Terephthalate (PBT), a specified engineering thermoplastic. The 4-102977-0 specifies only "Thermoplastic" without material designation, introducing material variability risk in long-term reliability and thermal performance.

Q: What inventory considerations apply to these parts?

A: The TSW-132-14-S-D has 1099 pieces in stock with Active status, supporting immediate procurement. The 4-102977-0 shows 773 pieces available but carries Obsolete status, indicating declining inventory and no future replenishment.
