The substitute parts TSM-103-02-L-SH, TSM-103-02-L-SH-A, and TSM-103-02-L-SH-LC differ only in specific features: the base TSM-103-02-L-SH contains no additional features, TSM-103-02-L-SH-A includes a Board Guide feature, and TSM-103-02-L-SH-LC includes a Board Lock feature. These feature variations do not affect core electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All listed parts maintain Active product status and ROHS3 compliance. Selection between TSM-103-02-LM-SH and its substitutes depends on design-specific requirements:

TSM-103-02-L-SH is the base configuration without additional mechanical features, suitable for standard board-to-board or cable applications where no alignment guidance is required.

TSM-103-02-L-SH-A includes Board Guide feature, applicable when connector alignment during mating is a design consideration.

TSM-103-02-L-SH-LC includes Board Lock feature, applicable when mechanical retention or positive locking during mated condition is required.

All parts share identical electrical characteristics, thermal performance, and compliance certifications. Selection is determined by mechanical interface requirements and assembly process specifications.

Frequently Asked Questions (FAQ)

Q: Can TSM-103-02-L-SH be used in place of TSM-103-02-LM-SH?

A: Yes. Both parts share identical pitch (0.100"), position count (3), contact material (Phosphor Bronze), operating temperature range (-55°C to 125°C), and compliance ratings (ROHS3, UL94 V-0). The difference is in mechanical features; TSM-103-02-L-SH lacks additional alignment or locking features present in some variants.

Q: What is the difference between TSM-103-02-L-SH-A and TSM-103-02-L-SH-LC?

A: TSM-103-02-L-SH-A includes a Board Guide feature for alignment assistance during mating. TSM-103-02-L-SH-LC includes a Board Lock feature for mechanical retention. Both maintain identical electrical and thermal specifications.

Q: Are all substitute parts MSL 1 rated?

A: TSM-103-02-LM-SH, TSM-103-02-L-SH, and TSM-103-02-L-SH-A are all MSL 1 (Unlimited). TSM-103-02-L-SH-LC is also MSL 1 (Unlimited). All parts have unlimited shelf life under standard storage conditions.

Q: Do these parts require different PCB footprints?

A: No. All parts maintain identical pitch (0.100"), number of positions (3), mounting type (Surface Mount, Right Angle), and contact dimensions. PCB footprints are interchangeable.

Q: What is the operating temperature range for all substitute parts?

A: All parts operate across -55°C to 125°C. This range is consistent across TSM-103-02-LM-SH, TSM-103-02-L-SH, TSM-103-02-L-SH-A, and TSM-103-02-L-SH-LC.
