Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMS-110-01-S-D are identified based on strict alignment of the following critical parameters:

• Connector Type & Position Count: Receptacle, 20 positions
• Pitch & Row Configuration: 0.050" (1.27mm) mating pitch, 2 rows, 0.100" (2.54mm) row spacing
• Mounting & Termination: Through-hole solder termination
• Fastening Mechanism: Push-pull fastening
• Contact Finish: Gold-plated mating contacts at 30.0µin (0.76µm) thickness
• Insulation Material & Color: Black insulation

The identified substitutes (TE Connectivity AMP Connectors 104078-1 and 5-104078-1) meet these core mechanical and electrical compatibility criteria. Variations in secondary parameters such as insulation height, operating temperature range, current rating, and material composition are documented to enable informed selection based on specific application requirements.

Engineering Selection Recommendations

SMS-110-01-S-D (Primary Part)

The SMS-110-01-S-D remains the primary selection for applications requiring 5A per-contact current capacity and operating temperatures up to 125°C. This part is ROHS3 compliant and features liquid crystal polymer insulation. Current inventory of 2000 units supports immediate availability.

5-104078-1 (Preferred Substitute)

The 5-104078-1 is the preferred substitute when SMS-110-01-S-D availability is constrained. This part maintains ROHS3 compliance and shares identical mechanical mating characteristics. The operating temperature range (-65°C ~ 105°C) and current rating (1A per contact) are reduced compared to the primary part. Applications limited to 1A per-contact operation and maximum 105°C operating temperature can utilize this substitute without functional compromise. Inventory of 1900 units provides strong supply continuity.

104078-1 (Secondary Substitute)

The 104078-1 offers mechanical compatibility identical to 5-104078-1 but carries "Not applicable" RoHS status. This part is suitable only for applications where RoHS compliance is not required. Current inventory of 922 units is available.

Frequently Asked Questions (FAQ)

Q: Can SMS-110-01-S-D be directly replaced with 104078-1 or 5-104078-1?

A: Direct mechanical and electrical substitution is possible when application requirements align with the reduced current rating (1A vs. 5A per contact) and operating temperature range (-65°C ~ 105°C vs. -55°C ~ 125°C) of the TE Connectivity parts. All three connectors share identical mating pitch (0.050"), position count (20), row configuration (2 rows, 0.100" spacing), and push-pull fastening.

Q: What is the impact of the 0.015" (0.38mm) difference in insulation height?

A: The SMS-110-01-S-D insulation height is 0.335" (8.51mm) while both TE Connectivity substitutes measure 0.350" (8.89mm). This 0.015" difference may affect board-to-board stacking height and mated connector clearance. Verify PCB layout and mating connector specifications before substitution.

Q: Are there RoHS compliance differences between substitutes?

A: The SMS-110-01-S-D and 5-104078-1 are both ROHS3 compliant. The 104078-1 carries "Not applicable" RoHS status. For applications requiring RoHS compliance, use SMS-110-01-S-D or 5-104078-1.

Q: What is the significance of the current rating difference (5A vs. 1A)?

A: The SMS-110-01-S-D supports 5A per contact, while both TE Connectivity substitutes are rated for 1A per contact. Applications requiring current levels between 1A and 5A per contact must use the SMS-110-01-S-D. For applications operating at 1A or below, the TE Connectivity parts are suitable.

Q: How do insulation materials differ between parts?

A: The SMS-110-01-S-D uses liquid crystal polymer (LCP) insulation, while the TE Connectivity substitutes use thermoplastic glass-filled material. Both materials are suitable for standard board-to-board connector applications. Verify material compatibility with specific environmental or chemical exposure requirements.

Q: What is the contact finish difference between post terminations?

A: The SMS-110-01-S-D features tin-plated posts, while 5-104078-1 also uses tin plating. The 104078-1 uses tin-lead plating with 150.0µin (3.81µm) thickness. For lead-free solder assembly processes, use SMS-110-01-S-D or 5-104078-1.
