Substitute Part Grouping Explanation

Substitute parts for the LSHM-140-L3.0-L-DV-A-S-TR are identified based on strict parametric equivalence within the Samtec Razor Beam™ LSHM series. The primary substitution criterion is the maintenance of all core electrical and mechanical parameters: 80-position count, 0.020" (0.50mm) pitch, 2-row configuration, self-mating hermaphroditic design, surface mount technology, gold contact finish at 10.0µin thickness, and identical board height of 0.175" (4.45mm).

The key differentiating parameter between the main part and its substitute is the packaging specification. The main part LSHM-140-L3.0-L-DV-A-S-TR utilizes standard packaging, while the substitute LSHM-140-03.0-L-DV-A-S-TR is supplied in Tape & Reel (TR) format. Both parts share identical connector specifications, compliance certifications (ROHS3), and MSL rating (1). Substitution is valid when packaging format does not constrain assembly or procurement requirements.

Parameter Comparison

Engineering Selection Recommendations

Both LSHM-140-L3.0-L-DV-A-S-TR and LSHM-140-03.0-L-DV-A-S-TR maintain Active product status with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and assembly process compatibility. The Tape & Reel (TR) format of LSHM-140-03.0-L-DV-A-S-TR is suitable for automated pick-and-place assembly operations, while standard packaging may be preferred for manual assembly or lower-volume applications. Both parts satisfy ROHS3 compliance and MSL 1 requirements for unrestricted moisture exposure during storage and handling.

Frequently Asked Questions (FAQ)

Q: Are LSHM-140-L3.0-L-DV-A-S-TR and LSHM-140-03.0-L-DV-A-S-TR electrically and mechanically interchangeable?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical connector specifications including 80-position count, 0.020" (0.50mm) pitch, 2-row configuration, self-mating hermaphroditic design, gold contact finish, and board height. The only difference is packaging format.

Q: What is the primary difference between these two part numbers?

A: The packaging specification differs. LSHM-140-L3.0-L-DV-A-S-TR uses standard packaging, while LSHM-140-03.0-L-DV-A-S-TR is supplied in Tape & Reel (TR) format for automated assembly processes.

Q: Can I use LSHM-140-03.0-L-DV-A-S-TR in place of LSHM-140-L3.0-L-DV-A-S-TR?

A: Substitution is valid when your assembly process and procurement workflow support Tape & Reel packaging. The connector itself is identical in all functional and compliance aspects.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant with MSL 1 rating, indicating unlimited moisture exposure tolerance during storage and handling.

Q: Are the mated stacking heights identical?

A: Yes. Both parts support identical mated stacking heights of 5.5mm, 6mm, 7mm, and 9mm, ensuring compatibility in multi-connector stack applications.
