Substitute Part Grouping Explanation

The LSHM-140-L4.0-L-DV-A-S-K-TR has one identified parametric equivalent: LSHM-140-04.0-L-DV-A-S-K-TR. Substitution is valid based on the following criteria:

Both parts share identical electrical and mechanical specifications:

• 80-position self-mating, non-gendered hermaphroditic connector
• 0.020" (0.50mm) pitch with 2-row configuration
• Surface mount hermaphroditic design with board guide and shielding
• Gold contact finish at 10.0µin (0.25µm) thickness
• Identical height above board: 0.215" (5.46mm)
• Matching mated stacking heights: 6.5mm, 7mm, 8mm, 10mm
• Identical packaging: Tape & Reel (TR)
• Both ROHS3 compliant with MSL 1 rating

The difference in part number designation (L4.0 versus 04.0) reflects internal Samtec nomenclature variation while maintaining full functional and mechanical interchangeability within the Razor Beam™ LSHM series.

Parameter Comparison

Engineering Selection Recommendations

Both the LSHM-140-L4.0-L-DV-A-S-K-TR and LSHM-140-04.0-L-DV-A-S-K-TR are Active status products from Samtec Inc. and are fully ROHS3 compliant. The substitute part LSHM-140-04.0-L-DV-A-S-K-TR offers higher inventory availability (1782 pcs versus 726 pcs) while maintaining identical electrical performance, mechanical dimensions, and compliance certifications. Selection between these parts should be based on supply chain availability and procurement timelines, as both parts are functionally equivalent for all applications requiring 80-position self-mating hermaphroditic connectors with 0.50mm pitch and surface mount configuration.

Frequently Asked Questions (FAQ)

Q: Are these connectors mechanically interchangeable? A: Yes. Both parts have identical height above board (0.215"), matching mated stacking heights (6.5mm, 7mm, 8mm, 10mm), and identical board guide and shielding features. They are fully mechanically interchangeable.

Q: Do these connectors have the same electrical specifications? A: Yes. Both parts feature 80 positions at 0.020" (0.50mm) pitch with identical gold contact finish (10.0µin thickness) and self-mating hermaphroditic design. Electrical performance is identical.

Q: Are both parts suitable for automated assembly? A: Yes. Both connectors include Pick and Place features and are supplied in Tape & Reel (TR) packaging, supporting automated surface mount assembly processes.

Q: What is the difference between the part numbers? A: The part number designation differs (L4.0 versus 04.0), but this reflects internal Samtec nomenclature variation. All other specifications, including electrical and mechanical parameters, are identical.

Q: Are both parts RoHS compliant? A: Yes. Both the LSHM-140-L4.0-L-DV-A-S-K-TR and LSHM-140-04.0-L-DV-A-S-K-TR are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I use these connectors in high-density applications? A: Yes. The 0.020" (0.50mm) pitch and 80-position configuration support high-density interconnect requirements. Both parts include shielding for signal integrity.
