Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LSHM-120-L2.5-L-DV-A-S-TR is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Self-mating, non-gendered, hermaphroditic design with identical electrical and mechanical interface
• Position Count & Pitch: 40 positions at 0.020" (0.50mm) pitch in 2-row configuration
• Mounting & Form Factor: Surface mount with identical height above board (0.156" / 3.96mm) and mated stacking height options
• Contact System: Gold plating at 10.0µin (0.25µm) thickness ensuring equivalent electrical performance
• Mechanical Features: Board guide and shielding present in all qualified substitutes
• Compliance & Environmental: ROHS3 compliance and MSL 1 rating maintained across all substitutes
• Packaging: Tape & Reel format for automated assembly compatibility

The substitute part LSHM-120-02.5-L-DV-A-S-TR shares identical electrical and mechanical specifications with the main part number, differing only in internal manufacturing designation. Both parts are sourced from Samtec Inc. within the same Razor Beam™ LSHM series and maintain equivalent performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the LSHM-120-L2.5-L-DV-A-S-TR and LSHM-120-02.5-L-DV-A-S-TR maintain Active product status within Samtec Inc.'s portfolio. Selection between these parts is based on availability and procurement requirements rather than technical differentiation.

Compliance Assurance: Both parts satisfy ROHS3 compliance requirements and carry MSL 1 rating, eliminating moisture sensitivity constraints for storage and handling. Export classification (EAR99) and tariff coding (HTSUS 8536.69.4040) are identical, supporting consistent supply chain documentation.

Inventory Considerations: The LSHM-120-02.5-L-DV-A-S-TR currently maintains higher inventory availability (2174 pcs) compared to the LSHM-120-L2.5-L-DV-A-S-TR (1056 pcs), supporting procurement lead time optimization.

Electrical & Mechanical Equivalence: Identical contact finish specifications, mated stacking height options, and board-level form factor ensure direct functional interchangeability in surface mount applications.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. Both parts feature identical 40-position, 0.020" pitch configurations with gold-plated contacts at 10.0µin thickness. Electrical performance and signal integrity characteristics are equivalent.

Q: Can I substitute one part number for the other on the same PCB assembly? A: Yes. Both parts share identical surface mount footprints, height above board (0.156"), and mated stacking heights (5mm, 5.5mm, 6.5mm, 8.5mm). No PCB redesign or assembly process modification is required.

Q: What is the difference between LSHM-120-L2.5-L-DV-A-S-TR and LSHM-120-02.5-L-DV-A-S-TR? A: These part numbers represent equivalent products within Samtec's manufacturing designation system.
