Engineering Selection Recommendations

TE Connectivity 292173 Series (1-292173-5, 2-292173-5, 292173-5): These parts are active products with ROHS3 compliance, providing modern alternatives to the obsolete S5B-PH-SM3-TB. The TE Connectivity variants feature glass-filled PA6T insulation material, which offers enhanced thermal and mechanical properties compared to the original PA46 composition. Contact length differences (0.165" vs. 0.130") and insulation height variations (0.228" vs. 0.217") must be evaluated against specific PCB layout and mating connector specifications. All three TE variants maintain the required 2.00mm pitch, 5-position configuration, and detent lock fastening. The primary distinction among TE options is insulation color (natural vs. black) and packaging format (Tape & Reel). Voltage ratings of 125VAC exceed the original 100V specification.

Sullins SWR201-NRTN-S05-HM-BG: This active product maintains mechanical compatibility with matching insulation height (0.217") and operating temperature range (-25°C ~ 85°C) identical to the original part. The SWR201 series uses PA46 insulation material consistent with the S5B-PH-SM3-TB. Current rating specification of 1A per contact is lower than the original 2A rating and must be evaluated against circuit requirements. ROHS3 compliance and 125V voltage rating support modern design standards. Tube packaging differs from typical Tape & Reel formats.

Compliance Consideration: The original S5B-PH-SM3-TB is RoHS non-compliant. All substitute parts listed are ROHS3 compliant, reflecting current regulatory requirements. Design teams must confirm that RoHS compliance is acceptable for the target application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 292173 series parts directly replace the S5B-PH-SM3-TB without PCB layout modifications?

A: The core mechanical interface (2.00mm pitch, 5-position, right-angle surface mount, detent lock) is identical. However, contact length differences (0.165" vs. 0.130") and insulation height variations (0.228" vs. 0.217") may require PCB layout verification. Mating connector depth and clearance specifications must be confirmed before implementation.

Q: What is the significance of the contact finish change from Tin-Lead to Tin?

A: The original S5B-PH-SM3-TB uses Tin-Lead contact finish, while all substitute parts use Tin finish. This reflects RoHS compliance requirements that restrict lead content. Tin finish provides equivalent electrical and mechanical performance for standard applications. Solder wettability and joint reliability remain within acceptable parameters for standard reflow and wave soldering processes.

Q: Are there current rating differences between the S5B-PH-SM3-TB and substitute parts?

A: The original part is rated at 2A. TE Connectivity variants specify current as "Varies by Wire Gauge," indicating current capacity depends on the mating connector wire gauge. The Sullins SWR201-NRTN-S05-HM-BG is rated at 1A per contact, which is lower than the original specification. Circuit current requirements must be evaluated against the selected substitute part's rating.

Q: What packaging options are available for these substitute parts?

A: TE Connectivity 292173 series parts are supplied in Tape & Reel (TR) format, suitable for automated assembly. The Sullins SWR201-NRTN-S05-HM-BG is supplied in Tube packaging. Packaging selection depends on production volume and assembly equipment compatibility.

Q: Does the insulation material change affect thermal or mechanical performance?

A: The TE Connectivity variants use glass-filled PA6T insulation, while the original and Sullins parts use PA46. Glass-filled PA6T offers improved thermal stability and mechanical strength. For applications operating within the specified temperature range (-25°C ~ 85°C), both materials are functionally equivalent. Material selection should be confirmed against specific thermal and mechanical stress requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. The original S5B-PH-SM3-TB is RoHS non-compliant. This compliance difference must be considered for applications subject to RoHS regulatory requirements.
