Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PRT-00139 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Connector Type: USB-B (USB TYPE-B)
• Gender: Receptacle
• Number of Contacts: 4
• Mounting Type: Through Hole, Right Angle
• Mounting Feature: Horizontal
• Termination: Solder
• Operating Temperature Range: -55°C ~ 85°C (minimum requirement)
• Current Rating: 1A (minimum requirement)
• Shielding: Shielded
• Contact Finish: Gold
• Material Flammability Rating: UL94 V-0
• Insulation Color: White

The substitute part KUSB-6-6-4-3-1-3-06 from KinnexA meets all critical electrical and mechanical parameters, enabling direct functional equivalence in applications requiring USB-B receptacle connectivity with identical form factor and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the PRT-00139 and KUSB-6-6-4-3-1-3-06 are active products with established manufacturing status and compliance certifications. Selection between these components should be based on the following engineering considerations:

PRT-00139 (SparkFun Electronics):

• ROHS3 compliant, meeting stringent European regulatory requirements
• Moisture Sensitivity Level 1 (Unlimited) provides maximum storage flexibility without time-dependent constraints
• Copper alloy shell material offers enhanced electromagnetic shielding characteristics
• Specified voltage rating of 30VAC provides explicit electrical performance documentation

KUSB-6-6-4-3-1-3-06 (KinnexA):

• REACH Unaffected status indicates compliance with chemical substance regulations
• Documented mating cycle rating of 1500 cycles provides explicit mechanical durability specification
• Steel shell material provides robust mechanical protection
• Moisture Sensitivity Level 2 (1 Year) requires controlled storage conditions within a one-year window

Both components satisfy the core electrical and mechanical requirements for USB-B receptacle applications. Selection should prioritize regulatory compliance requirements specific to the end application, storage environment constraints, and mechanical durability expectations.

Frequently Asked Questions (FAQ)

Q: Can KUSB-6-6-4-3-1-3-06 be used as a direct replacement for PRT-00139 in existing designs?

A: Yes. Both connectors share identical connector type (USB-B receptacle), contact configuration (4-position), mounting method (through-hole right-angle horizontal), termination type (solder), operating temperature range (-55°C to 85°C), current rating (1A), shielding (shielded), contact finish (gold), flammability rating (UL94 V-0), and insulation color (white). These parameters determine functional equivalence for PCB integration and mating compatibility.

Q: What are the material differences between these connectors?

A: The PRT-00139 features a copper alloy shell, while the KUSB-6-6-4-3-1-3-06 uses steel. Both materials provide shielding functionality. Copper alloy offers superior electromagnetic shielding performance, while steel provides enhanced mechanical robustness. Material selection should align with application-specific EMI/RFI requirements and mechanical stress conditions.

Q: How do the moisture sensitivity levels differ?

A: The PRT-00139 has MSL 1 (Unlimited), allowing indefinite storage without time constraints. The KUSB-6-6-4-3-1-3-06 has MSL 2 (1 Year), requiring component use within one year of packaging opening. Applications with extended inventory holding periods should prioritize the PRT-00139 to avoid moisture-related degradation risks.

Q: What compliance certifications apply to each connector?

A: The PRT-00139 is ROHS3 compliant, meeting European Union restrictions on hazardous substances. The KUSB-6-6-4-3-1-3-06 is REACH Unaffected, indicating compliance with European chemical substance regulations. Both hold UL94 V-0 flammability certification. Application regulatory requirements determine which certification status is necessary.

Q: Is the mating cycle specification relevant for component selection?

A: The KUSB-6-6-4-3-1-3-06 specifies 1500 mating cycles, while the PRT-00139 does not provide this specification. Applications requiring frequent connector mating/unmating cycles benefit from the documented durability rating of the KinnexA component. Applications with minimal mating cycles are not constrained by this parameter difference.

Q: Are there voltage rating differences between these connectors?

A: The PRT-00139 specifies 30VAC voltage rating. The KUSB-6-6-4-3-1-3-06 does not provide explicit voltage specification. Applications requiring documented voltage performance should reference the PRT-00139 specification. Standard USB-B applications operate at 5VDC, well below both specified and typical connector ratings.
