Substitute Part Grouping Explanation

Substitute parts for the LSHM-120-L4.0-L-DV-A-S-TR are identified based on strict parametric equivalence within the Razor Beam™ LSHM series. The substitution criteria are:

• Identical number of positions (40)
• Identical pitch specification (0.020" / 0.50mm)
• Identical connector type (Self Mating, Non-Gendered, Hermaphroditic)
• Identical mounting type (Surface Mount)
• Identical contact finish and thickness (Gold, 10.0µin)
• Identical height above board (0.215" / 5.46mm)
• Identical features (Board Guide, Shielded)
• Identical mated stacking heights (6.5mm, 7mm, 8mm, 10mm)
• Identical RoHS and MSL compliance

Parts meeting all these criteria are considered direct parametric equivalents and may be substituted without design modification.

Parameter Comparison

Engineering Selection Recommendations

Both the LSHM-120-L4.0-L-DV-A-S-TR and LSHM-120-04.0-L-DV-A-S-TR maintain Active product status with full RoHS3 compliance and MSL 1 rating. Selection between these parts is based on inventory availability and procurement lead times. The LSHM-120-04.0-L-DV-A-S-TR currently maintains higher inventory levels (1517 pcs) compared to the primary part (1132 pcs), making it suitable for applications where supply chain continuity is a priority. Both parts are certified to identical electrical and mechanical specifications and are suitable for direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can LSHM-120-04.0-L-DV-A-S-TR be used as a direct replacement for LSHM-120-L4.0-L-DV-A-S-TR?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including position count, pitch, connector type, mounting configuration, contact finish, and compliance certifications. Direct substitution is supported without design modification.

Q: What is the significance of the different part number designations (L4.0 vs 04.0)?

A: The part number variations reflect different manufacturing or packaging designations within the Samtec LSHM series. The provided parameters confirm that both parts are functionally and mechanically identical for the specified 40-position, 0.50mm pitch configuration.

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

A: No. Both parts maintain identical RoHS3 compliance status and MSL 1 rating. Both are certified to the same ECCN (EAR99) and HTSUS classifications.

Q: What are the mated stacking height options for this connector?

A: The LSHM-120 series supports four mated stacking heights: 6.5mm, 7mm, 8mm, and 10mm. Selection depends on application-specific spacing requirements.

Q: Is this connector suitable for high-reliability applications?

A: The LSHM-120 series features gold-plated contacts with 10.0µin thickness, board guide support, and shielding. MSL 1 rating indicates unlimited moisture sensitivity protection. These specifications support use in demanding interconnection applications.
