SMM-115-01-S-D Equivalent & Substitute Parts

Part Overview

The SMM-115-01-S-D is a 30-position receptacle connector from Samtec Inc.'s Tiger Eye™ SMM series, designed for board-to-board or cable applications with 0.079" (2.00mm) pitch spacing. This through-hole mounted connector features gold-plated mating contacts and is rated for 3.2A per contact at 350VAC, with an operating temperature range of -55°C to 125°C. The part is currently active in production and ROHS3 compliant.

Equivalent and substitute parts are identified when alternative connectors maintain compatibility across critical electrical and mechanical parameters, including pitch, number of positions, mounting type, contact configuration, and environmental ratings. Substitutes enable design flexibility, support supply chain alternatives, and provide options when the primary part experiences availability constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMM-115-01-S-D are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Connector type: Receptacle
• Number of positions: 30
• Pitch spacing: 0.079" (2.00mm)
• Number of rows: 2
• Row spacing: 0.079" (2.00mm)
• Mounting type: Through hole
• Termination: Solder
• Fastening type: Push-pull
• Contact type: Female socket
• Contact finish (mating): Gold
• Insulation color: Black

The identified substitutes (3-1470209-8 and 3-1734506-8) from TE Connectivity AMP Connectors maintain these core parameters. Variations in secondary parameters such as insulation height, contact length, operating temperature range, voltage rating, and contact finish thickness reflect design differences between manufacturers but do not prevent functional substitution when application requirements fall within the specified ranges of the substitute part.

Parameter Comparison

Engineering Selection Recommendations

All three connectors maintain active product status and comply with UL94 V-0 flammability requirements and MSL 1 moisture sensitivity ratings. The SMM-115-01-S-D and 3-1734506-8 are both ROHS3 compliant, while 3-1470209-8 carries RoHS compliance.

Selection between these parts depends on application-specific electrical and thermal requirements. The SMM-115-01-S-D supports the highest operating temperature range (-55°C to 125°C) and voltage rating (350VAC), making it suitable for demanding industrial and aerospace applications. The TE Connectivity substitutes (3-1470209-8 and 3-1734506-8) operate within -40°C to 105°C and are rated for 250VAC, appropriate for commercial and general industrial applications where these parameters are sufficient.

Mechanical fit considerations include insulation height and contact post length differences. The SMM-115-01-S-D has a lower insulation height (0.140") and longer contact post (0.120") compared to the TE Connectivity alternatives (0.177" height, 0.102" post length). PCB layout and mating connector specifications must accommodate these dimensional variations.

Frequently Asked Questions (FAQ)

Q: Can 3-1470209-8 or 3-1734506-8 be used as direct replacements for SMM-115-01-S-D?

A: These parts share identical pitch, position count, row configuration, mounting type, and fastening mechanism. Direct mechanical and electrical substitution is possible when application requirements fall within the operating temperature (-40°C to 105°C) and voltage (250VAC) specifications of the substitute parts. PCB layout must accommodate the dimensional differences in insulation height and contact post length.

Q: What are the key differences between the two TE Connectivity substitutes?

A: Both 3-1470209-8 and 3-1734506-8 share identical mechanical and electrical specifications. The primary differences are insulation material (Polyamide PA66 versus Thermoplastic) and contact material (Copper Alloy versus Phosphor Bronze). These material variations do not affect functional compatibility for standard applications.

Q: Are there temperature or voltage limitations when substituting?

A: Yes. The SMM-115-01-S-D operates from -55°C to 125°C at 350VAC. The TE Connectivity substitutes operate from -40°C to 105°C at 250VAC. Applications requiring operation below -40°C or above 105°C, or exceeding 250VAC, must use the original SMM-115-01-S-D specification.

Q: How do the contact finish thicknesses compare?

A: The SMM-115-01-S-D specifies 30.0µin (0.76µm) gold plating on mating contacts, while the TE Connectivity parts specify 8.00µin to 10.0µin. All three parts meet gold plating requirements for connector applications; the thickness variation reflects different manufacturing standards between suppliers.

Q: What packaging differences exist?

A: The SMM-115-01-S-D is supplied in tube packaging, while both TE Connectivity substitutes are supplied in tray packaging. Inventory availability differs: SMM-115-01-S-D has 1045 units, 3-1470209-8 has 6702 units, and 3-1734506-8 has 5598 units in stock.

Q: Are all three parts RoHS compliant?

A: The SMM-115-01-S-D and 3-1734506-8 are ROHS3 compliant. The 3-1470209-8 is RoHS compliant. All three meet RoHS requirements for lead-free applications.
