Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LSHM-120-L3.0-L-DV-A-S-K-TR are identified based on equivalence within the following critical parameters:

• Connector Type: Self mating, non-gendered, hermaphroditic configuration
• Position Count: 40 positions
• Pitch: 0.020" (0.50mm)
• Row Configuration: 2 rows
• Mounting Technology: Surface mount with board guide and pick-and-place compatibility
• Contact System: Gold-plated contacts at 10.0µin (0.25µm) thickness
• Mechanical Envelope: Height above board of 0.175" (4.45mm) with compatible mated stacking heights
• Compliance: ROHS3 compliant with MSL 1 rating
• Series Alignment: Razor Beam™ LSHM series

Substitutes maintain identical electrical and mechanical performance characteristics, ensuring direct interchangeability in applications requiring 40-position hermaphroditic self-mating connectors with 0.50mm pitch.

Parameter Comparison

Engineering Selection Recommendations

Both the LSHM-120-L3.0-L-DV-A-S-K-TR and LSHM-120-03.0-L-DV-A-S-K-TR maintain Active product status within the Samtec Razor Beam™ LSHM series. Both parts are ROHS3 compliant and carry MSL 1 (unlimited) moisture sensitivity ratings, indicating equivalent environmental and regulatory compliance profiles. Selection between these parts is based on application-specific inventory availability and supply chain considerations, as all electrical, mechanical, and compliance parameters are identical. The LSHM-120-03.0-L-DV-A-S-K-TR currently maintains higher inventory levels (1837 pcs) compared to the primary part (1035 pcs).

Frequently Asked Questions (FAQ)

Q: Are these connectors electrically interchangeable? A: Yes. Both parts feature identical 40-position, 0.50mm pitch configurations with self-mating, non-gendered hermaphroditic contact systems and gold-plated contact finishes. Electrical performance is equivalent.

Q: What is the difference between LSHM-120-L3.0-L-DV-A-S-K-TR and LSHM-120-03.0-L-DV-A-S-K-TR? A: The parts are parametrically equivalent. All specified electrical, mechanical, and compliance characteristics are identical. Differences exist only in part number designation within the Samtec naming convention.

Q: Can these connectors be used in the same PCB layout? A: Yes. Both connectors share identical mechanical envelopes, including 0.175" (4.45mm) height above board, 0.50mm pitch, and compatible mated stacking heights of 5.5mm, 6mm, 7mm, and 9mm. Board-level footprints are interchangeable.

Q: Are both parts RoHS compliant? A: Yes. Both LSHM-120-L3.0-L-DV-A-S-K-TR and LSHM-120-03.0-L-DV-A-S-K-TR are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity ratings.

Q: Which part should be selected for new designs? A: Either part is suitable for new designs. Selection should be based on supply chain availability, lead time requirements, and inventory levels. Both maintain Active product status with equivalent long-term support.
