• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 2
• Number of Rows: 1
• Mounting Type: Surface Mount, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Detent Lock
• Contact Shape: Square
• Contact Material: Brass
• Material Flammability Rating: UL94 V-0

Acceptable Variation Parameters:

• Insulation Material: Polyamide variants (PA46, PA6T) acceptable
• Contact Finish: Tin or Tin-Lead acceptable
• Insulation Color: Natural, Black, or Beige acceptable
• Voltage Rating: 100V minimum (125V acceptable)
• Current Rating: 2A minimum (Varies by Wire Gauge acceptable)
• Operating Temperature: -25°C ~ 85°C minimum range

The substitute parts listed below meet these criteria and are sourced from active product lines, providing improved availability and compliance status compared to the obsolete original part.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical specifications required for direct replacement of the S2B-PH-SM3-TB. Selection should be based on the following factors:

TE Connectivity AMP Connectors (1-292173-2, 2-292173-2, 292173-2, 3-292173-2): These parts are from the active CT series and carry ROHS3 compliance status. All four variants share identical electrical and mechanical characteristics with differences limited to packaging format and insulation color. The 292173-2 variant offers the highest inventory availability at 4100 pieces. These parts feature PA6T glass-filled insulation material, which provides enhanced mechanical properties compared to the original PA46 formulation. Voltage rating is increased to 125VAC, exceeding the original 100V specification.

Sullins Connector Solutions (SWR201-NRTN-S02-HM-BG): This part maintains the original PA46 insulation material and operating temperature range (-25°C ~ 85°C) identical to the S2B-PH-SM3-TB. It carries ROHS3 compliance and REACH unaffected status. The current rating is specified as 1A per contact, which is lower than the original 2A rating. This part is suitable for applications where the original thermal and material characteristics are critical. Packaging is provided in tube format.

Compliance Consideration: The original S2B-PH-SM3-TB is RoHS non-compliant. All substitute parts listed are ROHS3 compliant, making them suitable for applications requiring modern regulatory compliance. This represents a significant advantage for new designs and updated production runs.

Frequently Asked Questions (FAQ)

Q: Can I use TE Connectivity parts as direct replacements for the JST S2B-PH-SM3-TB?

A: Yes. The TE Connectivity 292173-2 series parts (1-292173-2, 2-292173-2, 292173-2, 3-292173-2) are functionally equivalent. All critical parameters match: 2-position, 2.00mm pitch, surface mount right-angle header with shrouded 4-wall construction, solder termination, and detent lock fastening. The primary differences are packaging format, insulation color, and material composition (PA6T glass-filled vs. PA46). Voltage and current ratings meet or exceed the original specification.

Q: What is the difference between the four TE Connectivity variants?

A: The four TE Connectivity parts (1-292173-2, 2-292173-2, 292173-2, 3-292173-2) differ only in packaging and insulation color. Variants 1-292173-2 and 3-292173-2 are supplied in Cut Tape (CT) format, while 2-292173-2 and 292173-2 are supplied in Tape & Reel (TR) format. Insulation colors are Natural for 1-292173-2 and 3-292173-2, and Black for 2-292173-2 and 292173-2. All four share identical electrical and mechanical specifications.

Q: Should I choose the Sullins SWR201-NRTN-S02-HM-BG part?

A: The Sullins part is suitable if your application requires the original PA46 insulation material and exact operating temperature range. However, the current rating is specified as 1A per contact, which is lower than the original 2A. This part is appropriate for lower-current applications or where material consistency with the original design is essential. For general replacement purposes, the TE Connectivity variants offer higher current capacity and improved material properties.

Q: What does the packaging format mean for my procurement?

A: Cut Tape (CT) packaging is suitable for smaller volume orders and manual assembly processes. Tape & Reel (TR) packaging is optimized for high-volume automated assembly lines. Tube packaging is typically used for lower-volume distribution. Select based on your production volume and assembly equipment capabilities.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status, whereas the original S2B-PH-SM3-TB is RoHS non-compliant. This makes the substitute parts suitable for applications requiring modern regulatory compliance with the Restriction of Hazardous Substances Directive.

Q: What is the difference in insulation material between the original and substitute parts?

A: The original S2B-PH-SM3-TB uses Polyamide (PA46) Nylon 4/6 insulation. The TE Connectivity variants use Polyamide (PA6T) Nylon 6T with glass filling, which provides enhanced mechanical strength and thermal stability. The Sullins part maintains the original PA46 formulation. Both materials meet UL94 V-0 flammability requirements.

Q: Can I mix different substitute parts in the same assembly?

A: All substitute parts are mechanically and electrically compatible with each other and with the original S2B-PH-SM3-TB. However, for consistency in production documentation and traceability, it is recommended to standardize on a single part number per assembly design.
