LSHM-120-L4.0-F-DV-A-S-K-TR Equivalent & Substitute Parts

Part Overview

The LSHM-120-L4.0-F-DV-A-S-K-TR is a 40-position self-mating, non-gendered hermaphroditic rectangular connector from Samtec Inc.'s Razor Beam™ LSHM series. This surface mount connector features gold-plated contacts and is designed for high-density interconnect applications requiring board-guided, pick-and-place compatible assembly. The part maintains Active product status with full RoHS3 compliance and MSL 1 rating, indicating unlimited moisture tolerance for storage and handling.

Alternative part numbers within this series become necessary when addressing specific application requirements such as connector height variations, inventory availability, or supply chain optimization while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution within the LSHM-120 series is determined by strict equivalence across the following critical parameters:

Connector Configuration: 40 positions, 2 rows, 0.020" (0.50mm) pitch
Connector Type: Self-mating, non-gendered, hermaphroditic design
Mounting Technology: Surface mount with board guide and pick-and-place compatibility
Contact System: Gold plating at 3.00µin thickness
Electrical Performance: Identical mated stacking heights (6.5mm, 7mm, 8mm, 10mm)
Compliance: ROHS3 and MSL 1 ratings
Packaging Format: Tape & Reel

The substitute part LSHM-120-04.0-F-DV-A-S-K-TR maintains all these parameters identically. The alphanumeric designation difference reflects internal Samtec nomenclature but does not indicate functional or electrical variation. Both parts are interchangeable at the circuit board assembly level.

Engineering Selection Recommendations

Both LSHM-120-L4.0-F-DV-A-S-K-TR and LSHM-120-04.0-F-DV-A-S-K-TR are Active products with identical compliance certifications (ROHS3, MSL 1, EAR99 ECCN classification, and HTSUS code 8536.69.4040). Selection between these parts should be based on inventory availability and supply chain considerations rather than technical performance differentiation.

The LSHM-120-04.0-F-DV-A-S-K-TR currently maintains higher inventory levels (2172 pcs vs. 1033 pcs), making it the preferred choice for high-volume production schedules or extended lead-time mitigation strategies. Both parts are suitable for applications requiring hermaphroditic self-mating connectivity with 40-position, 0.50mm-pitch configuration in surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Are LSHM-120-L4.0-F-DV-A-S-K-TR and LSHM-120-04.0-F-DV-A-S-K-TR electrically identical?

A: Yes. Both connectors provide identical electrical performance with 40 positions, 0.50mm pitch, gold-plated contacts at 3.00µin thickness, and support the same mated stacking heights (6.5mm, 7mm, 8mm, 10mm).

Q: Can these parts be used interchangeably on the same circuit board?

A: Yes. Both parts are pin-compatible and mechanically interchangeable. They share identical mounting footprints, height above board (0.215"), and surface mount assembly requirements.

Q: What is the significance of the alphanumeric difference in the part numbers?

A: The designation difference (L4.0 vs. 04.0) reflects Samtec's internal nomenclature system but does not indicate functional, electrical, or mechanical variation. Both parts are equivalent within the Razor Beam™ LSHM series.

Q: Are both parts RoHS3 compliant?

A: Yes. Both LSHM-120-L4.0-F-DV-A-S-K-TR and LSHM-120-04.0-F-DV-A-S-K-TR maintain full ROHS3 compliance and MSL 1 (unlimited moisture tolerance) ratings.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should prioritize inventory availability and supply chain lead times. The LSHM-120-04.0-F-DV-A-S-K-TR currently offers higher stock levels.

Q: Are there any packaging differences between these parts?

A: No. Both parts are supplied in Tape & Reel (TR) packaging format, suitable for automated pick-and-place assembly processes.
