Substitute Part Grouping Explanation

Substitution eligibility for USB-B-S-S-B-TH-R-TR is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: USB-B (USB TYPE-B)
• Specifications: USB 2.0
• Number of Contacts: 4
• Gender: Receptacle
• Mounting Type: Through Hole, Right Angle
• Mounting Feature: Horizontal
• Termination: Solder
• Features: Board Lock
• Operating Temperature: -50°C ~ 85°C
• Voltage - Rated: 30VAC
• Mating Cycles: 1500
• Contact Finish: Gold
• Shell/Shielding Material: Steel
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

Variable Parameters (Non-Critical for Substitution):

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

Substitute parts must maintain identical electrical and mechanical specifications while potentially differing in packaging configuration and cosmetic attributes. All identified substitutes are manufactured by Samtec Inc. within the USB-B series and retain active product status.

Parameter Comparison

Engineering Selection Recommendations

USB-B-S-F-B-TH-TR (Substitute 1): This part is electrically and mechanically equivalent to the main part number. The primary difference is packaging format: Cut Tape (CT) versus Tape & Reel (TR). This substitute is suitable for applications where Cut Tape packaging is acceptable or preferred for lower-volume production runs. Higher current inventory (1486 units) provides improved procurement availability. Insulation color differs (Black vs. White) but does not affect electrical performance or compliance status. ROHS3 compliance and UL94 V-0 flammability rating are maintained.

USB-B-S-S-B-TH-TR (Substitute 2): This part is a direct parametric equivalent with identical packaging format (Tape & Reel). All electrical, mechanical, and compliance specifications match the main part number. Insulation color is identical (White). This substitute provides seamless interchangeability for design and manufacturing purposes. Current inventory (803 units) supports production continuity.

Both substitutes maintain active product status, ROHS3 compliance, and UL94 V-0 flammability certification. Selection between substitutes depends on packaging requirements and inventory availability rather than technical performance criteria.

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-R-TR?

A: Yes. Both parts are electrically and mechanically equivalent USB 2.0 Type-B receptacle connectors with identical contact count, mounting configuration, operating temperature range, voltage rating, and mating cycle specifications. The difference in packaging format (Cut Tape vs. Tape & Reel) does not affect functional compatibility. Insulation color variation (Black vs. White) is cosmetic and does not impact electrical performance or compliance.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape packaging provides components on cut segments of carrier tape, typically used for lower-volume orders or manual assembly processes. Both packaging formats contain identical components with the same electrical and mechanical specifications.

Q: Are all three parts ROHS3 compliant?

A: Yes. The main part USB-B-S-S-B-TH-R-TR and both substitute parts USB-B-S-F-B-TH-TR and USB-B-S-S-B-TH-TR are ROHS3 compliant. All three parts meet UL94 V-0 flammability requirements.

Q: Does insulation color affect connector performance?

A: No. Insulation color is a cosmetic attribute and does not affect electrical performance, mechanical function, or compliance status. The main part and Substitute 2 feature white insulation, while Substitute 1 features black insulation. All three parts are functionally equivalent.

Q: Which substitute should be selected for high-volume production?

A: USB-B-S-S-B-TH-TR (Substitute 2) is recommended for high-volume production due to Tape & Reel packaging, which is optimized for automated assembly processes. This part maintains identical specifications to the main part number and supports seamless manufacturing integration.

Q: Which substitute should be selected for lower-volume or manual assembly?

A: USB-B-S-F-B-TH-TR (Substitute 1) with Cut Tape packaging is suitable for lower-volume applications or manual assembly processes. This packaging format provides flexibility for smaller production quantities while maintaining full electrical and mechanical equivalence.

Q: Are there any temperature or voltage limitations when using substitute parts?

A: No. All three parts operate across the identical temperature range (-50°C to 85°C) and are rated for 30VAC. Mating cycle specifications (1500 cycles) are identical across all parts. No additional limitations apply when using substitute parts.
