LSHM-140-L2.5-F-DV-A-S-TR Equivalent & Substitute Parts

Part Overview

The LSHM-140-L2.5-F-DV-A-S-TR is an 80-position self-mating, non-gendered hermaphroditic rectangular connector from Samtec Inc.'s Razor Beam™ LSHM series. This surface mount connector features gold-plated contacts, board guide, and shielding, designed for applications requiring high-density interconnection with 0.020" (0.50mm) pitch spacing. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when packaging or inventory requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LSHM-140-L2.5-F-DV-A-S-TR is determined by strict equivalence across the following critical parameters:

• Number of positions: 80
• Pitch spacing: 0.020" (0.50mm)
• Connector type: Self mating, non-gendered, hermaphroditic
• Mounting method: Surface mount
• Contact finish: Gold at 3.00µin thickness
• Physical height above board: 0.156" (3.96mm)
• Mated stacking height options: 5mm, 5.5mm, 6.5mm, 8.5mm
• Compliance: ROHS3, MSL 1

The identified substitute part differs only in packaging configuration (Tape & Reel versus standard packaging), which does not affect electrical or mechanical performance. All other specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the LSHM-140-L2.5-F-DV-A-S-TR and LSHM-140-02.5-F-DV-A-S-TR maintain Active product status and full ROHS3 compliance. Selection between these parts should be based on packaging and supply chain requirements. The Tape & Reel packaged variant (LSHM-140-02.5-F-DV-A-S-TR) offers higher current inventory availability (1648 units versus 971 units) and is suitable for automated assembly processes. Both parts are electrically and mechanically interchangeable for all applications requiring 80-position, 0.50mm pitch self-mating connectors with gold contacts and surface mount configuration.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. Both parts are identical in electrical performance, contact configuration, pitch spacing, and signal integrity characteristics. They differ only in packaging format.

Q: What is the difference between standard packaging and Tape & Reel? A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly equipment. Standard packaging is suitable for manual assembly or lower-volume applications. The connector itself is functionally identical.

Q: Can I use the Tape & Reel version in place of the standard packaged version? A: Yes, provided your assembly process supports Tape & Reel format. The electrical and mechanical specifications are identical.

Q: Are both parts ROHS3 compliant? A: Yes. Both LSHM-140-L2.5-F-DV-A-S-TR and LSHM-140-02.5-F-DV-A-S-TR meet ROHS3 compliance requirements.

Q: What does MSL 1 (Unlimited) mean? A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling.

Q: Are the mated stacking heights the same for both parts? A: Yes. Both parts support identical mated stacking height options: 5mm, 5.5mm, 6.5mm, and 8.5mm.
