Substitute Part Grouping Explanation

Substitute parts for the KUSBX-SMT4-ASFS1N-B30TR are identified based on strict electrical and mechanical parameter equivalence within the KUSBX-SMT series. The substitution logic is based on the following key parameters that must remain constant:

• Connector Type: USB-A (USB TYPE-A) receptacle configuration
• Contact Count: 4-position
• USB Specification: USB 2.0 compliance
• Mounting Configuration: Surface mount, right-angle, horizontal orientation
• Electrical Performance: 1.5A current rating, 30V voltage rating
• Environmental Compliance: Operating temperature range -55°C ~ 85°C, UL94 V-0 flammability rating, ROHS3 compliance
• Physical Construction: Shielded design with gold-plated contacts and brass shielding material
• Termination Method: Solder termination

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Packaging variations (tape & reel specifications) do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both the KUSBX-SMT4-ASFS1N-B30TR and KUSBX-SMT4-ASFS1N-BTR are active production parts manufactured by Kycon, Inc., within the KUSBX-SMT series. All electrical, mechanical, and environmental parameters are identical between the two parts. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for consumer and industrial applications.

The KUSBX-SMT4-ASFS1N-BTR offers higher inventory availability (1890 pieces versus 1101 pieces), which may provide supply chain advantages for high-volume production requirements. Selection between these parts should be based on procurement lead time, inventory availability, and project timeline requirements, as functional performance and compliance characteristics are equivalent.

Frequently Asked Questions (FAQ)

Q: Are KUSBX-SMT4-ASFS1N-B30TR and KUSBX-SMT4-ASFS1N-BTR functionally interchangeable?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (USB 2.0, 1.5A, 30V), mechanical configuration (surface mount, right-angle, horizontal), and environmental ratings (-55°C ~ 85°C operating temperature, UL94 V-0). They are direct substitutes within the KUSBX-SMT series.

Q: What are the key parameters that determine substitutability for this USB connector?

A: Substitutability is determined by: connector type (USB-A receptacle), contact count (4-position), USB specification (USB 2.0), mounting configuration (surface mount, right-angle, horizontal), current and voltage ratings (1.5A, 30V), operating temperature range (-55°C ~ 85°C), shielding type (shielded), contact finish (gold), and compliance certifications (ROHS3, UL94 V-0).

Q: Does packaging affect the substitutability of these parts?

A: No. Both parts are supplied in Tape & Reel (TR) packaging. Packaging format does not affect functional substitutability; it only impacts handling, storage, and assembly process considerations.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both KUSBX-SMT4-ASFS1N-B30TR and KUSBX-SMT4-ASFS1N-BTR are ROHS3 compliant and carry UL94 V-0 material flammability certification, meeting current regulatory requirements for electronic component applications.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on inventory availability and procurement requirements. The KUSBX-SMT4-ASFS1N-BTR currently has higher stock levels (1890 pieces), which may provide supply chain advantages.

Q: Can these connectors be used in high-temperature applications?

A: Both parts are rated for operating temperatures from -55°C to 85°C. Applications requiring operation outside this range require alternative connector selection.

Q: What is the expected connector lifespan in terms of mating cycles?

A: Both parts are rated for 1500 mating cycles, representing the expected mechanical durability under normal connection and disconnection operations.
