Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSS-120-05-L-D-RA is determined by strict alignment of the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 40
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Contact Material: Phosphor Bronze
• Insulation Material: Polybutylene Terephthalate (PBT)
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The TST-120-05-L-D-RA qualifies as a direct substitute based on matching all critical electrical, mechanical, and environmental parameters. Minor variations in insulation material composition (glass-filled PBT) and application designation (Board to Cable/Wire versus Board to Board or Cable) do not affect functional interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the TSS-120-05-L-D-RA and TST-120-05-L-D-RA maintain Active product status with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on application-specific requirements and supply availability. The TST-120-05-L-D-RA offers higher inventory availability (1009 pcs versus 832 pcs) and includes current rating specification (3.4A per contact), providing additional design documentation. Both parts satisfy identical electrical, mechanical, and environmental operating parameters within the specified constraints.

Frequently Asked Questions (FAQ)

Q: Can TST-120-05-L-D-RA replace TSS-120-05-L-D-RA in existing designs?

A: Yes. Both parts share identical connector type, contact configuration, pitch, mounting orientation, shrouding, contact finishes, and operating temperature range. The glass-filled PBT insulation material in the TST variant does not affect functional interchangeability.

Q: What is the difference between the TSS and TST series designations?

A: The TSS series is designated for board-to-board or cable applications, while the TST series is designated for board-to-cable/wire applications. Both maintain identical electrical and mechanical specifications for the 40-position, 2.54mm pitch configuration.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, UL94 V-0 rated, and carry identical moisture sensitivity level (MSL 1 - Unlimited) classifications.

Q: Does the glass-filled PBT insulation in the TST variant affect performance?

A: The glass-filled PBT composition in the TST-120-05-L-D-RA does not alter the functional performance parameters specified for this connector category. Both materials meet the same flammability and environmental operating requirements.

Q: What is the mating pitch and row spacing for these connectors?

A: Both connectors feature 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing, maintaining standard 2-row, 40-position configuration.
