Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-103-08-SS-S is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Contact Type: Male Pin
• Number of Positions: 3
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Contact Material: Phosphor Bronze
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Operating Temperature Range: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0

Mechanical Compatibility Parameters:

• Connector Type: Header
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Length - Mating: 0.230" (5.84mm)
• Contact Length - Post: 0.200" (5.08mm)
• Overall Contact Length: 0.530" (13.46mm)
• Insulation Height: 0.100" (2.54mm)
• Contact Shape: Square

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Two substitute parts meet these criteria: TSW-103-08-S-S and HMTSW-103-08-S-S-230. Both maintain full electrical and mechanical compatibility with the main part while differing in product status and insulation material composition.

Parameter Comparison

Engineering Selection Recommendations

TSW-103-08-SS-S (Primary Selection)

The TSW-103-08-SS-S remains the recommended primary selection. This part maintains active product status with the highest inventory availability at 1159 units. Full ROHS3 compliance and UL94 V-0 flammability rating satisfy standard regulatory requirements. The PBT insulation material provides established performance characteristics across the -55°C to 125°C operating range.

TSW-103-08-S-S (Alternative - Limited Availability)

The TSW-103-08-S-S provides electrical and mechanical equivalence to the main part. However, this part is discontinued at DiGi Electronics, indicating reduced long-term availability. Selection of this substitute should be limited to applications where existing inventory must be utilized or where design legacy requirements mandate TSW series components. The 1132 units in current stock represent a finite supply.

HMTSW-103-08-S-S-230 (Alternative - Active Production)

The HMTSW-103-08-S-S-230 offers an active production alternative within the Flex Stack series. This part maintains full electrical and mechanical compatibility while substituting Liquid Crystal Polymer (LCP) insulation material for PBT. The LCP composition provides enhanced dimensional stability and lower moisture absorption characteristics. A specified current rating of 3A is provided for this variant. The natural insulation color differs from the black finish of the main part. With 796 units in stock, this substitute supports long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can TSW-103-08-S-S be used as a direct replacement for TSW-103-08-SS-S?

A: Yes. The TSW-103-08-S-S maintains identical electrical and mechanical specifications across all critical parameters including contact type, pitch, contact geometry, termination method, and operating temperature range. Both parts are ROHS3 compliant with UL94 V-0 flammability ratings. However, the TSW-103-08-S-S is discontinued at DiGi Electronics, limiting future availability.

Q: What is the primary difference between HMTSW-103-08-S-S-230 and TSW-103-08-SS-S?

A: The HMTSW-103-08-S-S-230 substitutes Liquid Crystal Polymer (LCP) insulation material for the Polybutylene Terephthalate (PBT) used in the TSW-103-08-SS-S. Both materials meet UL94 V-0 flammability requirements and maintain equivalent electrical performance. The LCP variant provides improved dimensional stability and moisture resistance. The insulation color differs (natural versus black). All other electrical and mechanical parameters remain identical.

Q: Are there any compatibility concerns when substituting HMTSW-103-08-S-S-230 for TSW-103-08-SS-S?

A: No compatibility concerns exist for standard through-hole solder mounting applications. Both parts maintain identical contact geometry, pitch spacing, and mating interface specifications. The insulation material change from PBT to LCP does not affect electrical performance or mechanical fit. The natural insulation color of the HMTSW variant may differ in visual appearance but does not impact functional compatibility.

Q: Which substitute part should be selected for new designs?

A: For new designs requiring active production status and long-term supply assurance, the HMTSW-103-08-S-S-230 is the appropriate selection. This part maintains active product status with established inventory levels. The LCP insulation material provides enhanced environmental performance characteristics. The TSW-103-08-SS-S remains suitable for existing designs with established supply chains.

Q: What is the current rating specification for these connector parts?

A: The TSW-103-08-SS-S and TSW-103-08-S-S do not specify a current rating in their technical documentation. The HMTSW-103-08-S-S-230 specifies a 3A current rating. For applications requiring explicit current rating specifications, the HMTSW variant provides documented electrical performance data.

Q: Are all three parts ROHS3 compliant?

A: Yes. The TSW-103-08-SS-S, TSW-103-08-S-S, and HMTSW-103-08-S-S-230 are all ROHS3 compliant. All three parts maintain UL94 V-0 material flammability ratings and Moisture Sensitivity Level 1 (Unlimited) classifications, meeting standard regulatory and environmental requirements.
