Key Parameters

Substitute Part Grouping Explanation

The LSHM-120-L2.5-F-DV-A-S-K-TR has one identified parametric equivalent within the Razor Beam™ LSHM series. Substitution eligibility is determined by the following critical parameters:

• Connector Type: Self Mating, Non-Gendered, Hermaphroditic
• Number of Positions: 40
• Pitch: 0.020" (0.50mm)
• Number of Rows: 2
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Contact Finish Thickness: 3.00µin (0.076µm)
• Features: Board Guide, Pick and Place, Shielded
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part LSHM-120-02.5-F-DV-A-S-K-TR shares all critical electrical and mechanical parameters with the main part, ensuring direct functional compatibility in applications requiring 40-position self-mating connectors with 0.50mm pitch and gold contact finish.

Parameter Comparison

Engineering Selection Recommendations

Both the LSHM-120-L2.5-F-DV-A-S-K-TR and LSHM-120-02.5-F-DV-A-S-K-TR are Active status products from Samtec Inc. and maintain full ROHS3 compliance. The substitute part carries identical electrical and mechanical specifications, ensuring compatibility in applications requiring 40-position self-mating rectangular connectors with 0.50mm pitch and gold contact finish. Selection between these parts should be based on inventory availability and supply chain considerations, as both parts meet all specified compliance and performance requirements.

Frequently Asked Questions (FAQ)

Q: Are these connectors electrically interchangeable? A: Yes. Both parts share identical electrical specifications including 40 positions, 0.020" (0.50mm) pitch, gold contact finish at 3.00µin thickness, and self-mating hermaphroditic configuration.

Q: Can the substitute part be used in existing PCB designs? A: Yes. The substitute part maintains identical mounting type (Surface Mount), height above board (0.156"), mated stacking heights (5mm, 5.5mm, 6.5mm, 8.5mm), and mechanical features (Board Guide, Pick and Place, Shielded).

Q: Are there differences in packaging or handling? A: Both parts are supplied in Tape & Reel (TR) packaging with identical Moisture Sensitivity Level 1 (Unlimited), requiring no special storage or handling precautions.

Q: Do both parts meet the same compliance standards? A: Yes. Both parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the difference between the part numbers? A: The part numbers differ in the stacking height designation within the model string. Both parts support the same range of mated stacking heights and are functionally equivalent for applications requiring 40-position self-mating connectors.
