Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMS-110-01-G-D are identified based on the following critical parameters that determine functional compatibility:

• Connector Type & Position Count: Both substitute parts (104078-1 and 5-104078-1) are 20-position receptacle connectors matching the SMS-110-01-G-D
• Pitch & Row Configuration: All parts maintain 0.050" (1.27mm) mating pitch with 2-row, 0.100" (2.54mm) row spacing
• Mounting & Termination: Through-hole solder termination with push-pull fastening is consistent across all parts
• Contact Finish - Mating: Gold plating on mating contacts is maintained in all substitute options
• Board-to-Board Style: All parts are designed for board-to-board interconnection

The TE Connectivity AMP Connectors parts (104078-1 and 5-104078-1) represent the primary substitute options within the AMPMODU System 50 series. These parts share the same mechanical footprint and electrical interface characteristics as the SMS-110-01-G-D, enabling direct substitution in applications where the specified parameters are met.

Engineering Selection Recommendations

SMS-110-01-G-D (Primary Part) Select this part when ROHS3 compliance is required and the application demands the specified operating temperature range of -55°C to 125°C. The higher current rating of 5A per contact supports higher-power applications. LCP insulation material provides superior dimensional stability and chemical resistance.

5-104078-1 (Preferred Substitute) This part is the recommended substitute when SMS-110-01-G-D availability is constrained. It maintains ROHS3 compliance and offers the highest inventory availability (1900 units). The operating temperature range of -65°C to 105°C covers most standard industrial applications. The tin post finish eliminates lead content concerns in lead-free assembly processes.

104078-1 (Secondary Substitute) This part serves as an alternative when 5-104078-1 is unavailable. RoHS status is not applicable, which may present compliance considerations for certain end-use applications. The tin-lead post finish requires evaluation against assembly and environmental requirements. Inventory availability is moderate at 922 units.

All substitute parts maintain mechanical compatibility through identical pitch, row spacing, mounting type, and fastening mechanisms. Applications operating below 1A per contact and within the -65°C to 105°C temperature range are suitable for TE Connectivity substitutes. Applications requiring the full 5A per contact rating or extended high-temperature operation (-55°C to 125°C) should retain the SMS-110-01-G-D.

Frequently Asked Questions (FAQ)

Q: Can 104078-1 or 5-104078-1 be used as direct replacements for SMS-110-01-G-D? A: Both TE Connectivity parts share identical mechanical footprints and mating interfaces. Direct substitution is possible for applications operating at 1A or below per contact and within the -65°C to 105°C temperature range. Applications requiring 5A per contact or the extended temperature range of -55°C to 125°C must use the SMS-110-01-G-D.

Q: What are the key differences between the substitute parts? A: The primary difference between 104078-1 and 5-104078-1 is the post contact finish (tin-lead versus tin) and RoHS compliance status. Both parts are electrically and mechanically equivalent. The 5-104078-1 is preferred for new designs due to ROHS3 compliance and lead-free post finish.

Q: Are there any PCB layout considerations when substituting these parts? A: All three parts maintain the same 0.050" (1.27mm) pitch and 0.100" (2.54mm) row spacing. Insulation height differs slightly (SMS-110-01-G-D: 0.335", substitutes: 0.350"), which may affect board clearance in space-constrained designs. Verify PCB footprint clearances before substitution.

Q: What is the impact of different contact finish thicknesses? A: The SMS-110-01-G-D has 10.0µin (0.25µm) gold plating on mating contacts, while substitutes have 30.0µin (0.76µm). Thicker plating on substitutes provides enhanced wear resistance and contact durability over extended mating cycles. This difference does not affect electrical performance for standard applications.

Q: Which substitute part should be selected for new designs? A: The 5-104078-1 is recommended for new designs. It offers ROHS3 compliance, lead-free post finish, highest inventory availability, and active product status. Use SMS-110-01-G-D only when the 5A per contact rating or -55°C to 125°C temperature range is specifically required.

Q: Are voltage ratings a consideration for substitution? A: The SMS-110-01-G-D does not specify a voltage rating. The TE Connectivity substitutes are rated for 30VAC. For applications requiring higher voltage ratings, verify that 30VAC is sufficient or confirm that the SMS-110-01-G-D meets the application voltage requirement through the manufacturer.
