Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-103-08-SS-S-RA is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 3
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Allowable Variations:

• Insulation Material: Polybutylene Terephthalate (PBT) or Liquid Crystal Polymer (LCP)
• Insulation Height: 0.119" (3.02mm) or 0.122" (3.10mm)
• Insulation Color: Black or Natural
• Series Designation: TSW or HTSW
• Moisture Sensitivity Level: 1 (Unlimited) or Not Applicable

All three substitute parts meet these criteria and are classified as direct equivalents for the TSW-103-08-SS-S-RA.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the TSW-103-08-SS-S-RA. Selection between equivalent parts should be based on the following factors:

Series Selection (TSW vs. HTSW): The TSW series (TSW-103-08-SS-S-RA and TSW-103-08-S-S-RA) utilizes Polybutylene Terephthalate (PBT) insulation material with Moisture Sensitivity Level 1 (Unlimited). The HTSW series (HTSW-103-08-S-S-RA and HTSW-103-08-SM-S-RA) utilizes Liquid Crystal Polymer (LCP) insulation material with Moisture Sensitivity Level Not Applicable. Both series meet UL94 V-0 flammability requirements and operate across the identical temperature range.

Insulation Material Considerations: PBT-based connectors (TSW series) and LCP-based connectors (HTSW series) are both compliant alternatives. Insulation height varies between 0.119" (3.02mm) for PBT and 0.122" (3.10mm) for LCP, representing a 0.003" (0.08mm) difference.

Inventory Availability: TSW-103-08-S-S-RA offers the highest inventory level at 1135 pieces, followed by HTSW-103-08-S-S-RA at 1113 pieces, TSW-103-08-SS-S-RA at 1031 pieces, and HTSW-103-08-SM-S-RA at 726 pieces.

Frequently Asked Questions (FAQ)

Q: Can HTSW series connectors replace TSW series connectors in existing designs?

A: Yes. Both series maintain identical pitch (0.100" / 2.54mm), position count (3), contact geometry, contact finish specifications, and operating temperature range (-55°C ~ 125°C). The primary difference is insulation material composition (PBT vs. LCP) and insulation height variation (0.003" / 0.08mm). Verify PCB layout accommodates the insulation height difference before substitution.

Q: What is the significance of the insulation height difference between 0.119" and 0.122"?

A: The 0.003" (0.08mm) difference reflects the material properties of PBT versus LCP insulation. This variation may affect board-to-board spacing in high-density applications. Confirm PCB design clearances support the substitute part's insulation height.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts, including TSW-103-08-SS-S-RA, HTSW-103-08-S-S-RA, HTSW-103-08-SM-S-RA, and TSW-103-08-S-S-RA, maintain ROHS3 compliance.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean for TSW series parts?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life without special moisture control requirements during storage and handling. HTSW series parts are classified as Not Applicable for MSL, indicating LCP material does not require moisture sensitivity management.

Q: Are contact finish specifications identical across all substitute parts?

A: Yes. All parts feature gold-plated mating contacts (30.0µin / 0.76µm thickness) and tin-plated posts, ensuring consistent electrical performance and solderability.

Q: Can these connectors be used interchangeably in cable and board-to-board applications?

A: Yes. All parts are classified as Board to Board or Cable style connectors with identical through-hole, right-angle mounting configuration and solder termination.
