Substitute Part Grouping Explanation

The LSHM-150-04.0-F-DV-A-S-K-TR qualifies as a parametric equivalent to the LSHM-150-L4.0-F-DV-A-S-K-TR based on the following substitution criteria:

Critical Matching Parameters:

Identical connector type: Self-mating, non-gendered, hermaphroditic
Identical position count: 100 positions
Identical pitch: 0.020" (0.50mm)
Identical row configuration: 2 rows
Identical mounting technology: Surface mount
Identical contact finish and thickness: Gold, 3.00µin (0.076µm)
Identical height above board: 0.215" (5.46mm)
Identical mated stacking height options: 6.5mm, 7mm, 8mm, 10mm
Identical feature set: Board guide, pick and place, shielded

Engineering Selection Recommendations

Both the LSHM-150-L4.0-F-DV-A-S-K-TR and LSHM-150-04.0-F-DV-A-S-K-TR are Active products with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on:

Inventory Availability: The LSHM-150-04.0-F-DV-A-S-K-TR offers higher stock availability (1287 pcs) compared to the LSHM-150-L4.0-F-DV-A-S-K-TR (730 pcs), making it suitable for high-volume production requirements.

Compliance Status: Both parts meet ROHS3 requirements and carry MSL 1 rating, ensuring compatibility with standard surface mount assembly processes and long-term storage without moisture sensitivity concerns.

Functional Equivalence: Complete parameter alignment ensures direct substitution without circuit redesign, PCB layout modification, or assembly process changes.

Frequently Asked Questions (FAQ)

Q: Can LSHM-150-04.0-F-DV-A-S-K-TR be used as a direct replacement for LSHM-150-L4.0-F-DV-A-S-K-TR?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including position count, pitch, contact finish, stacking heights, and mounting characteristics. Direct substitution is supported without design modifications.

Q: Are there any differences in contact reliability or signal integrity between these parts?

A: No. Both parts feature identical gold contact finish thickness (3.00µin), pitch (0.020"), and connector geometry, ensuring equivalent electrical performance and contact reliability.

Q: Do both parts support the same mated stacking height configurations?

A: Yes. Both parts support identical mated stacking heights of 6.5mm, 7mm, 8mm, and 10mm, allowing flexible system integration options.

Q: What is the significance of the part number designation difference?

A: The designation difference (L4.0 versus 04.0) does not reflect electrical or mechanical parameter variations. Both parts belong to the same LSHM-150 base product family and are functionally equivalent.

Q: Are both parts suitable for automated pick-and-place assembly?

A: Yes. Both parts include pick-and-place features and are supplied in Tape & Reel packaging, supporting standard surface mount assembly processes.
