Key Parameters

Substitute Part Grouping Explanation

Substitution for the BSS-025-01-L-D-A-TR is determined by equivalence in the following critical parameters:

• Number of Positions: 50
• Pitch: 0.025" (0.64mm)
• Number of Rows: 2
• Connector Type: Socket, Center Strip Contacts
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Contact Finish Thickness: 10.0µin (0.25µm)
• Mated Stacking Height: 5mm
• Height Above Board: 0.135" (3.43mm)
• Features: Board Guide
• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)

The primary difference between the main part and its substitute is the packaging format. The BSS-025-01-L-D-A-TR is supplied in Tape & Reel (TR) format, while the substitute BSS-025-01-L-D-A is supplied in Tray format. Both parts are electrically and mechanically identical, with differences limited to distribution and handling methods.

Parameter Comparison

Engineering Selection Recommendations

Both the BSS-025-01-L-D-A-TR and BSS-025-01-L-D-A are Active products from Samtec Inc. with identical ROHS3 compliance and MSL ratings. Selection between these parts is based on packaging requirements and procurement logistics rather than electrical or mechanical performance. The Tape & Reel format (TR) is optimized for automated assembly processes, while the Tray format is suitable for manual handling or alternative assembly workflows. Both parts meet the same regulatory and environmental compliance standards.

Frequently Asked Questions (FAQ)

Q: Are the BSS-025-01-L-D-A-TR and BSS-025-01-L-D-A electrically identical?

A: Yes. Both parts have identical electrical specifications, including 50 positions, 0.025" pitch, gold contact finish at 10.0µin thickness, and all other functional parameters.

Q: What is the difference between Tape & Reel and Tray packaging?

A: Tape & Reel (TR) packaging is designed for high-speed automated pick-and-place assembly equipment. Tray packaging is used for manual handling or alternative assembly methods. The connector itself is unchanged.

Q: Can I use the Tray-packaged part in place of the Tape & Reel part?

A: Yes, provided your assembly process can accommodate Tray packaging. The electrical and mechanical performance are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both BSS-025-01-L-D-A-TR and BSS-025-01-L-D-A are ROHS3 compliant.

Q: What does MSL 1 (Unlimited) mean?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning the component has unlimited shelf life under normal storage conditions and requires no special moisture control during handling or storage.

Q: Are there any mechanical differences between these parts?

A: No. Both parts have identical mechanical specifications: 50 positions, 2 rows, 0.025" pitch, 5mm mated stacking height, 0.135" height above board, and board guide features.
