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 Criteria:

• Connector Type: USB-B (USB TYPE-B)
• Specifications: USB 2.0
• Number of Contacts: 4
• Gender: Receptacle
• Voltage Rating: 30VAC
• Mating Cycles: 1500

Mechanical Equivalence Criteria:

• Mounting Type: Through Hole, Right Angle
• Mounting Feature: Horizontal
• Termination: Solder
• Contact Finish: Gold
• Shell/Shielding Material: Steel

Compliance Equivalence Criteria:

• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• ECCN: EAR99

Substitute parts must maintain all electrical, mechanical, and compliance parameters. Variations in packaging format (Tape & Reel vs. Cut Tape) and insulation color do not affect functional equivalence. Moisture Sensitivity Level differences are permissible when the substitute part maintains or exceeds environmental protection standards.

Parameter Comparison

Engineering Selection Recommendations

The USB-B-S-F-B-TH-TR qualifies as a direct functional equivalent to the USB-B-S-S-B-TH-TR based on complete parameter alignment across electrical, mechanical, and compliance specifications. Both parts are manufactured by Samtec Inc., maintain Active product status, and satisfy ROHS3 compliance requirements.

Selection between these parts should be based on:

Packaging Requirements: The main part is supplied in Tape & Reel format, suitable for automated assembly processes. The substitute part is supplied in Cut Tape format, appropriate for manual assembly or lower-volume applications.

Inventory Availability: The substitute part (USB-B-S-F-B-TH-TR) maintains higher inventory levels (1486 Pcs) compared to the main part (803 Pcs), providing supply chain flexibility.

Environmental Conditions: Both parts operate across the identical temperature range (-50°C ~ 85°C) and maintain equivalent environmental protection ratings. The Moisture Sensitivity Level difference does not impact functional performance in standard operating environments.

Frequently Asked Questions (FAQ)

Q: Can USB-B-S-F-B-TH-TR be used as a direct replacement for USB-B-S-S-B-TH-TR in production designs?

A: Yes. Both connectors maintain identical electrical specifications (USB 2.0, 4-position receptacle), mechanical configuration (through-hole, right-angle, horizontal mounting), and compliance certifications (UL94 V-0, ROHS3). The parts are functionally interchangeable at the circuit board level.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape packaging supplies the same components on shorter tape segments, suitable for manual assembly or lower-volume production runs. Both packaging formats contain identical components.

Q: Does the insulation color difference (White vs. Black) affect connector performance?

A: No. Insulation color is a cosmetic specification that does not impact electrical performance, mechanical fit, or environmental protection. Selection between white and black insulation is based on design aesthetics or internal documentation standards only.

Q: Are there any temperature or voltage limitations when substituting these parts?

A: No. Both parts maintain identical operating temperature ranges (-50°C ~ 85°C) and voltage ratings (30VAC). Substitution does not introduce any thermal or electrical constraints.

Q: What does Moisture Sensitivity Level (MSL) mean for these connectors?

A: MSL indicates the connector's sensitivity to moisture absorption during storage and handling. The main part lists MSL as Not Applicable, indicating minimal moisture sensitivity. The substitute part lists MSL 1 (Unlimited), indicating the highest moisture tolerance. This difference does not affect functional performance in standard operating environments.

Q: Can these connectors be used interchangeably in existing PCB designs without layout modifications?

A: Yes. Both connectors share identical mounting specifications (through-hole, right-angle, horizontal orientation) and footprint requirements. PCB layouts designed for either part accommodate the other without modification.

Q: What is the mating cycle rating, and why is it important?

A: The mating cycle rating of 1500 indicates the connector is rated for 1500 insertion and withdrawal cycles under normal operating conditions. Both parts maintain this identical rating, ensuring equivalent mechanical durability and service life.
