Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MUSB-05-F-B-SM-A-R-TR is determined by strict alignment with the following core parameters:

Critical Matching Parameters:

• Connector Type: USB - mini B (5-position)
• Gender: Receptacle
• USB Specification: USB 2.0
• Mounting Type: Surface Mount, Right Angle
• Termination: Solder
• Features: Board Guide, Solder Retention
• Mating Cycles: 1500
• Shielding: Unshielded
• Contact Finish: Gold
• Material Flammability Rating: UL94 V-0

Allowable Variations:

• Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel)
• Manufacturer identity
• Shell/Shielding material (Copper Alloy or Brass)
• Operating temperature range (provided minimum operating temperature does not fall below -50°C)
• Voltage rating (provided rated voltage is 30V or higher)
• Current rating (provided current rating is 1A or higher, or unspecified)

All identified substitute parts meet these criteria and are classified as parametric equivalents suitable for direct component substitution in the MUSB-05-F-B-SM-A-R-TR application.

Parameter Comparison

Engineering Selection Recommendations

MUSB-05-F-B-SM-A-TR (Samtec Inc., Cut Tape & Digi-Reel)

This substitute maintains identical electrical and mechanical specifications to the primary part, with the primary difference being packaging format. Both are manufactured by Samtec Inc. and carry ROHS3 compliance and MSL 1 ratings. Selection of this variant is appropriate when Cut Tape or Digi-Reel packaging aligns with assembly line requirements or when Tape & Reel format is unavailable.

690-005-299-043 (Mercury United Electronics, Inc., Cut Tape & Digi-Reel)

This Mercury part is a parametric equivalent with identical connector geometry, contact count, and USB 2.0 specification. Operating temperature range is -30°C to 80°C, which is narrower than the primary part. Current rating is specified at 1A. Shell material is brass rather than copper alloy. This part carries ROHS3 compliance and MSL 1 rating. Selection is appropriate for applications within the specified temperature range and when Mercury component sourcing is preferred.

934TR (Keystone Electronics, Tape & Reel)

This Keystone part matches the primary part in connector type, contact configuration, and mounting specification. Current rating is specified at 1A. Shell material is brass. Operating temperature range and material flammability rating are not specified. This part carries ROHS3 compliance and MSL 1 rating. Selection is appropriate when Keystone sourcing is required and operating conditions fall within typical commercial ranges.

Frequently Asked Questions (FAQ)

Q: Can MUSB-05-F-B-SM-A-TR (Samtec, Cut Tape) be used as a direct replacement for MUSB-05-F-B-SM-A-R-TR (Samtec, Tape & Reel)?

A: Yes. Both parts are manufactured by Samtec Inc. and share identical electrical and mechanical specifications. The difference is packaging format only. Tape & Reel (TR) packaging is supplied on continuous reels for high-volume automated assembly, while Cut Tape (CT) and Digi-Reel packaging are supplied in smaller quantities. Component functionality and PCB mounting are identical.

Q: What are the key differences between the Samtec and Mercury parts?

A: The primary differences are manufacturer identity, shell material (Copper Alloy vs. Brass), and operating temperature range. The Mercury 690-005-299-043 operates from -30°C to 80°C, compared to -50°C to 85°C for the Samtec part. Both maintain USB 2.0 compliance, 5-position receptacle configuration, and 1500 mating cycle rating. Selection depends on application temperature requirements and supplier preference.

Q: Is the Keystone 934TR suitable for all applications using the MUSB-05-F-B-SM-A-R-TR?

A: The Keystone 934TR is mechanically and electrically compatible for USB 2.0 mini B receptacle applications. However, operating temperature range and material flammability rating are not specified for this part. Verification against specific application requirements is necessary before selection.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life under normal storage conditions and does not require special moisture control measures during storage or handling. This applies to all identified substitute parts.

Q: Are all substitute parts RoHS3 compliant?

A: MUSB-05-F-B-SM-A-TR (Samtec, Cut Tape), 690-005-299-043 (Mercury), and 934TR (Keystone) are all specified as ROHS3 compliant. The primary part MUSB-05-F-B-SM-A-R-TR does not specify RoHS status in the provided data.

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

A: The Samtec parts (both TR and CT variants) are rated to 85°C maximum. The Mercury part is rated to 80°C maximum. The Keystone part does not specify operating temperature. For applications requiring operation above 80°C, only the Samtec variants are suitable based on provided specifications.

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

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for high-speed automated pick-and-place assembly. Cut Tape (CT) and Digi-Reel packaging supply components in smaller quantities on tape strips, suitable for lower-volume assembly or manual handling. Component specifications and performance are identical; packaging format only affects supply chain and assembly process compatibility.
