LSHM-150-L4.0-L-DV-A-S-TR Equivalent & Substitute Parts

Part Overview

The LSHM-150-L4.0-L-DV-A-S-TR is a 100-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 high-density interconnect applications. The part is Active in product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent substitute parts may be required due to inventory availability, lead time optimization, or design revision requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LSHM-150-L4.0-L-DV-A-S-TR is determined by strict equivalence across the following critical parameters:

• Connector type: Self-mating, non-gendered, hermaphroditic configuration
• Position count: 100 positions
• Pitch specification: 0.020" (0.50mm)
• Row configuration: 2 rows
• Mounting technology: Surface mount
• Contact material and finish: Gold plating at 10.0µin thickness
• Mechanical envelope: Height above board of 0.215" (5.46mm)
• Regulatory compliance: ROHS3 and MSL 1 rating

The identified substitute part LSHM-150-04.0-L-DV-A-S-TR maintains identical electrical and mechanical specifications across all these parameters, differing only in internal stacking height designation, which does not affect board-level compatibility or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the LSHM-150-L4.0-L-DV-A-S-TR and LSHM-150-04.0-L-DV-A-S-TR are Active products with identical ROHS3 compliance and MSL 1 ratings. Selection between these parts is based on inventory availability and lead time requirements. The LSHM-150-04.0-L-DV-A-S-TR currently maintains higher stock levels (1508 pcs) compared to the primary part (841 pcs), making it suitable for applications requiring expedited procurement. Both parts satisfy equivalent regulatory and environmental compliance requirements for deployment in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Are these connectors mechanically interchangeable on the PCB? A: Yes. Both parts share identical height above board (0.215"), pitch (0.020"), position count (100), and row configuration (2). They are direct mechanical substitutes with no PCB layout modifications required.

Q: Do the connectors support the same mated stacking heights? A: Yes. Both parts support identical mated stacking heights of 6.5mm, 7mm, 8mm, and 10mm, ensuring compatibility with existing mating connector designs.

Q: What is the difference between the part numbers? A: The difference in the part number designations (L4.0 versus 04.0) reflects internal stacking height specifications that do not affect board-level electrical or mechanical performance. Both configurations are functionally equivalent for standard applications.

Q: Are both parts RoHS compliant? A: Yes. Both LSHM-150-L4.0-L-DV-A-S-TR and LSHM-150-04.0-L-DV-A-S-TR are ROHS3 compliant with identical contact finish specifications (gold, 10.0µin thickness).

Q: What is the moisture sensitivity rating for these connectors? A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processing.

Q: Can these connectors be used in high-density interconnect applications? A: Yes. The 0.020" (0.50mm) pitch and 100-position configuration support high-density interconnect requirements. The board guide and shielding features provide mechanical stability and electromagnetic protection in dense packaging environments.
