Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for USB-B Type-B receptacle connectors is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• USB 2.0 specification compliance
• 4-position contact configuration
• 30VAC rated voltage
• 1500 mating cycle rating
• Gold contact finish

Mechanical Equivalence Requirements:

• USB-B receptacle gender
• Through-hole mounting technology
• Right-angle, horizontal mounting orientation
• Solder termination method
• Board lock feature
• Steel shell/shielding material

Compliance Equivalence Requirements:

• UL94 V-0 flammability rating
• ROHS3 compliance
• EAR99 ECCN classification
• 8536.69.4040 HTSUS code

Allowable Variations:

• Packaging format (Tape & Reel vs. Cut Tape)
• Insulation color (White vs. Black)
• Moisture Sensitivity Level (MSL) designation

The two identified substitutes—USB-B-S-F-B-TH-TR and USB-B-S-S-B-TH-TR—meet all electrical, mechanical, and compliance requirements while differing only in packaging and cosmetic attributes.

Parameter Comparison

Engineering Selection Recommendations

USB-B-S-F-B-TH-TR (Substitute 1): This part is functionally equivalent to the main part across all electrical and mechanical specifications. The primary difference is packaging format (Cut Tape vs. Tape & Reel) and insulation color (Black vs. White). This substitute is suitable for applications where insulation color is not a design constraint and Cut Tape packaging is acceptable for assembly processes. Higher inventory availability (1486 pieces) supports supply chain continuity.

USB-B-S-S-B-TH-TR (Substitute 2): This part maintains identical electrical, mechanical, and compliance characteristics to the main part, with matching Tape & Reel packaging and white insulation color. The only distinguishing feature is the contact configuration designation within the part number. This substitute provides direct compatibility with existing assembly specifications and design documentation. Lower inventory (803 pieces) should be considered in procurement planning.

Both substitutes carry active product status and full ROHS3 compliance, ensuring regulatory alignment with current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can USB-B-S-F-B-TH-TR be used as a direct replacement for USB-B-S-F-W-TH-R-TR?

A: Yes, USB-B-S-F-B-TH-TR is electrically and mechanically equivalent. The differences are packaging format (Cut Tape instead of Tape & Reel) and insulation color (Black instead of White). If insulation color is not specified in your design requirements, this substitute is fully compatible.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging provides components on cut segments of carrier tape, typically used for lower-volume or manual assembly processes. Both formats contain identical components; the difference is in delivery and handling method.

Q: Are all three parts compliant with current environmental regulations?

A: Yes. All three parts—USB-B-S-F-W-TH-R-TR, USB-B-S-F-B-TH-TR, and USB-B-S-S-B-TH-TR—are ROHS3 compliant and carry UL94 V-0 flammability ratings, meeting current regulatory requirements for electronic component manufacturing and use.

Q: Can I mix these parts in the same production batch?

A: Electrical and mechanical compatibility is identical across all three parts, allowing them to function interchangeably in circuit applications. However, if your assembly process or design documentation specifies packaging format or insulation color, mixing parts may create traceability or quality control issues. Consult your manufacturing and quality procedures.

Q: What is the operating temperature range for these connectors?

A: All three parts operate across the temperature range of -50°C to 85°C, supporting applications in industrial, automotive, and consumer electronics environments within this thermal envelope.

Q: How many mating cycles are these connectors rated for?

A: All three parts are rated for 1500 mating cycles, defining the expected mechanical durability for repeated connection and disconnection operations under normal use conditions.
