TSS-115-02-S-D-LL Equivalent & Substitute Parts

Part Overview

The TSS-115-02-S-D-LL is a rectangular connector header manufactured by Samtec Inc., classified as a through-hole board-to-board or cable connector with 30 positions arranged in 2 rows. This connector is part of the Flex Stack TSS series and maintains Active product status. Alternative components may be required due to inventory constraints, regional availability, packaging preferences, or specific application requirements where pitch tolerance or operating temperature ranges differ from the primary specification.

Key Parameters

Substitute Part Grouping Explanation

The DF1BZ-30DP-2.5DSA from Hirose Electric Co Ltd qualifies as a substitute based on the following alignment criteria:

Matching Parameters:

• Connector Type: Header (both)
• Contact Type: Male Pin (both)
• Number of Positions: 30 (both)
• Number of Rows: 2 (both)
• Mounting Type: Through Hole (both)
• Shrouding: Shrouded - 4 Wall (both)
• Fastening Type: Push-Pull (both)
• Material Flammability Rating: UL94 V-0 (both)
• Moisture Sensitivity Level: 1 - Unlimited (both)
• ECCN Classification: EAR99 (both)

Tolerance Considerations: The DF1BZ-30DP-2.5DSA operates at a pitch of 0.098" (2.50mm) compared to the TSS-115-02-S-D-LL pitch of 0.100" (2.54mm). This represents a 0.002" (0.04mm) difference in mating pitch and row spacing. The substitute also operates within a narrower temperature range (-35°C ~ 85°C) and carries a 250V voltage rating specification not provided for the primary part.

Parameter Comparison

Engineering Selection Recommendations

Both the TSS-115-02-S-D-LL and DF1BZ-30DP-2.5DSA maintain Active product status and comply with RoHS regulations. The primary distinction lies in pitch specification and operating temperature envelope.

Selection of the TSS-115-02-S-D-LL is appropriate for applications requiring the full -55°C to 125°C operating range and the specified 0.100" (2.54mm) pitch with gold-plated mating contacts.

Selection of the DF1BZ-30DP-2.5DSA is appropriate for applications where the -35°C to 85°C operating range is sufficient and where the 0.098" (2.50mm) pitch tolerance is acceptable. This substitute is available in tray packaging rather than bulk.

Both connectors carry UL94 V-0 flammability certification and unlimited moisture sensitivity classification, supporting equivalent reliability in standard industrial environments.

Frequently Asked Questions (FAQ)

Q: Can the DF1BZ-30DP-2.5DSA directly replace the TSS-115-02-S-D-LL in existing PCB designs?

A: Direct mechanical and electrical substitution requires verification that the 0.002" (0.04mm) pitch difference does not exceed design tolerances. PCB footprints designed for 0.100" (2.54mm) pitch may not accommodate the 0.098" (2.50mm) pitch without modification.

Q: What is the significance of the contact finish difference between gold and tin?

A: The TSS-115-02-S-D-LL features gold-plated mating contacts, which provide enhanced corrosion resistance and lower contact resistance. The DF1BZ-30DP-2.5DSA uses tin-plated mating contacts, suitable for standard industrial applications but with different wear and oxidation characteristics.

Q: Are both parts suitable for high-temperature applications?

A: The TSS-115-02-S-D-LL supports continuous operation to 125°C. The DF1BZ-30DP-2.5DSA is rated to 85°C maximum. Applications requiring sustained operation above 85°C require the TSS-115-02-S-D-LL.

Q: What packaging differences exist between these parts?

A: The TSS-115-02-S-D-LL is supplied in bulk packaging. The DF1BZ-30DP-2.5DSA is supplied in tray packaging. Packaging selection may affect handling, storage, and integration into automated assembly processes.

Q: Do both connectors meet the same compliance standards?

A: Both parts carry UL94 V-0 flammability ratings and unlimited moisture sensitivity classification (MSL 1). The TSS-115-02-S-D-LL is ROHS3 compliant; the DF1BZ-30DP-2.5DSA is RoHS compliant. Both are classified as EAR99 for export control purposes.
