Parameter Comparison

Engineering Selection Recommendations

KUSBX-SMT-CS2-B30TR (Kycon, Inc.) — Parametric Equivalent This part is a direct parametric equivalent with identical electrical specifications, operating temperature range, and current ratings. Both parts are RoHS compliant with MSL 1 rating. The primary difference is RoHS3 compliance status on the substitute versus RoHS compliance on the main part. This part is suitable for direct replacement in applications requiring identical performance characteristics.

USB4080-03-A (GCT) — Similar Part This GCT connector maintains USB 3.2 Gen 2 functionality and identical mounting configuration. Key differences include higher current rating (5A versus 3A), 48VDC voltage rating versus 100VAC, and narrower operating temperature range (-25°C to 85°C versus -40°C to 85°C). This part is suitable for applications where the higher current capacity and voltage rating are compatible with system requirements, provided the reduced lower temperature limit is acceptable.

USB-C31-S-RA-CS1E-BK-T/R (Adam Tech) — Parametric Equivalent This Adam Tech connector matches the KUSBX-SMT-CS2-BTR across all critical parameters including operating temperature range, mounting type, and mating cycles. Current rating extends to 5A. No voltage rating is specified for this part. ROHS3 compliance and REACH unaffected status are documented. This part is suitable for direct replacement in applications compatible with the specified current ratings.

All substitute parts maintain UL94 V-0 flammability rating, gold contact finish, and 10,000 mating cycle rating. Selection should be based on specific application requirements regarding current capacity, voltage rating, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can KUSBX-SMT-CS2-B30TR be used as a direct replacement for KUSBX-SMT-CS2-BTR? A: Yes. Both parts are manufactured by Kycon, Inc., and share identical electrical specifications, mounting characteristics, operating temperature range (-40°C to 85°C), current ratings (0.25A, 1.25A, 3A), and mating cycle rating (10,000). The primary difference is RoHS3 compliance status on the substitute part.

Q: What are the key differences between the Kycon KUSBX-SMT-CS2-BTR and the GCT USB4080-03-A? A: Both connectors support USB 3.2 Gen 2 with identical 24-position receptacle configuration and horizontal surface mount right-angle orientation. The GCT part features higher current capacity (5A versus 3A) and 48VDC voltage rating versus 100VAC. The GCT part has a narrower operating temperature range (-25°C to 85°C versus -40°C to 85°C). Selection depends on whether the application requires the lower temperature operation and specific voltage/current characteristics.

Q: Are all substitute parts available in the same packaging format? A: No. The Kycon parts (KUSBX-SMT-CS2-BTR and KUSBX-SMT-CS2-B30TR) and Adam Tech part (USB-C31-S-RA-CS1E-BK-T/R) are supplied in Tape & Reel (TR) packaging. The GCT USB4080-03-A is supplied in Cut Tape (CT) and Digi-Reel® packaging. Packaging format should be verified against procurement and assembly requirements.

Q: Do all substitute parts meet the same compliance standards? A: All parts are UL94 V-0 rated and MSL 1 (Unlimited). The main part is RoHS compliant. The substitute parts are ROHS3 compliant. The GCT and Adam Tech parts have REACH Unaffected status documented. Compliance requirements should be verified against specific application and regional standards.

Q: What is the mating cycle rating for all parts? A: All parts, including the main KUSBX-SMT-CS2-BTR and all substitute parts, are rated for 10,000 mating cycles.

Q: Can the Adam Tech USB-C31-S-RA-CS1E-BK-T/R be used in applications requiring 100VAC rating? A: The Adam Tech part does not specify a voltage rating. Applications requiring specific voltage compliance should use parts with documented voltage specifications. The Kycon KUSBX-SMT-CS2-BTR and KUSBX-SMT-CS2-B30TR are rated for 100VAC; the GCT USB4080-03-A is rated for 48VDC.
