Engineering Selection Recommendations

TE Connectivity AMP Connectors (1-292173-3, 2-292173-3, 292173-3, 3-292173-3)

All four TE Connectivity variants are active products with ROHS3 compliance and REACH unaffected status. These parts maintain identical core electrical and mechanical specifications to the S3B-PH-SM3-TB, including 3-position 2.00mm pitch, shrouded 4-wall design, and solder termination. The TE parts feature higher voltage rating (125VAC vs. 100V) and improved insulation material (PA6T glass-filled vs. PA46). Differences in contact length (0.165" vs. 0.130") and insulation height (0.228" vs. 0.217") are within acceptable tolerance for standard board-to-cable applications. Available in multiple packaging formats (Tape & Reel and Cut Tape) with substantial inventory levels.

Sullins Connector Solutions (SWR201-NRTN-S03-HM-BG)

The SWR201-NRTN-S03-HM-BG is an active product with ROHS3 compliance and REACH unaffected status. This part matches the original S3B-PH-SM3-TB in insulation height (0.217"), operating temperature range (-25°C ~ 85°C), and insulation material composition (PA46). Voltage rating is equivalent (125V vs. 100V). The primary distinction is current rating specification: 1A per contact versus the original 2A rating. This part is suitable for applications where current requirements do not exceed 1A per contact.

Frequently Asked Questions (FAQ)

Q: Can I use TE Connectivity 292173-3 series parts as direct replacements for the S3B-PH-SM3-TB?

A: Yes. The TE Connectivity 292173-3 variants (1-292173-3, 2-292173-3, 292173-3, 3-292173-3) are functionally equivalent. All maintain the critical substitution parameters: 3-position header, 2.00mm pitch, surface mount right-angle configuration, shrouded 4-wall design, and solder termination with detent lock. The parts are active products with superior compliance status (ROHS3 vs. RoHS non-compliant). Minor dimensional variations in contact length and insulation height do not affect standard board-to-cable interconnect applications.

Q: What is the difference between the four TE Connectivity part numbers?

A: The four TE Connectivity variants differ in packaging format and insulation color. Parts 1-292173-3, 2-292173-3, and 292173-3 are supplied in Tape & Reel format with varying insulation colors (Natural or Black). Part 3-292173-3 is supplied in Cut Tape format with Natural insulation color. All four parts are electrically and mechanically identical and interchangeable for design purposes.

Q: Is the Sullins SWR201-NRTN-S03-HM-BG suitable for all applications using the S3B-PH-SM3-TB?

A: The Sullins part is suitable for applications where current requirements do not exceed 1A per contact. The original S3B-PH-SM3-TB is rated for 2A total current. If your application requires 2A current capacity, use the TE Connectivity 292173-3 series instead. The Sullins part is otherwise equivalent in electrical and mechanical specifications.

Q: Why do the TE Connectivity parts have higher voltage ratings (125VAC) than the original (100V)?

A: Higher voltage ratings indicate improved electrical performance and safety margin. A 125VAC rating is compatible with 100V applications and provides additional design flexibility. This is not a limitation but an enhancement.

Q: What is the significance of ROHS3 compliance on the substitute parts?

A: ROHS3 compliance indicates the parts meet current Restriction of Hazardous Substances regulations, whereas the original S3B-PH-SM3-TB is RoHS non-compliant. For new designs or applications subject to RoHS requirements, the substitute parts are necessary. For legacy systems, either compliant or non-compliant parts may be acceptable depending on regulatory requirements.

Q: Are there packaging considerations when selecting between these substitute parts?

A: Yes. TE Connectivity parts are available in Tape & Reel (TR) or Cut Tape (CT) packaging, suitable for automated assembly. The Sullins part is supplied in Tube packaging, which may require manual handling. Select packaging based on your assembly process requirements and volume needs.

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

A: Yes, all listed substitute parts are functionally equivalent and can be used interchangeably in the same design, provided current requirements do not exceed the rated capacity of the selected part. Verify contact length and insulation height compatibility with your specific PCB layout and mating connector design.
