MUSBC51101 USB-A Stacked Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The MUSBC51101 is an active, production-status USB-A Type-A stacked receptacle connector manufactured by Amphenol ICC (Commercial Products). This connector is designed for panel mount, through-hole applications requiring USB 2.0 compliance with IP67 ingress protection. The part is RoHS compliant and rated for 1500 mating cycles with a 1.5A current capacity. Substitute parts are identified when identical electrical and mechanical parameters are required for component procurement, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MUSBC51101 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Connector Type & Form Factor: USB-A Type-A, Stacked configuration
• Contact Count & Gender: 8-position receptacle
• USB Specification Compliance: USB 2.0
• Mounting Configuration: Panel mount, through-hole with flange and vertical orientation
• Electrical Performance: 1.5A current rating, shielded design
• Environmental Ratings: IP67 ingress protection, -40°C to 105°C operating range
• Durability: 1500 mating cycles minimum
• Material & Finish Standards: Gold-plated contacts, copper alloy shielding, UL94 V-0 flammability rating
• Regulatory Compliance: RoHS compliant, MSL 1

Only parts matching all these parameters across the MUSB series are classified as parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

Both MUSBC51101 and MUSBC511N1 are active production parts from Amphenol ICC (Commercial Products) with identical electrical, mechanical, and environmental specifications. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation.

MUSBC51101 is suitable for applications requiring a stacked USB-A receptacle connector with:

• USB 2.0 protocol compliance
• Panel mount through-hole installation
• IP67 environmental sealing
• Extended temperature operation (-40°C to 105°C)
• RoHS compliance for regulated markets

MUSBC511N1 provides equivalent functionality and is interchangeable with MUSBC51101 for all applications meeting the above criteria. Both parts maintain identical performance characteristics, durability ratings (1500 mating cycles), and regulatory certifications.

Selection should prioritize part availability and lead time. Both parts are manufactured to the same specifications and carry identical compliance certifications (RoHS, UL94 V-0, MSL 1).

Frequently Asked Questions (FAQ)

Q: Are MUSBC51101 and MUSBC511N1 fully interchangeable?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (USB 2.0, 1.5A rating), mechanical configuration (8-position stacked receptacle, panel mount through-hole), environmental ratings (IP67, -40°C to 105°C), and durability (1500 mating cycles). They are direct substitutes for each other.

Q: What does "stacked" mean in the connector configuration?

A: Stacked refers to the physical arrangement where multiple USB ports are integrated into a single connector assembly with a vertical mounting orientation. This configuration is used in applications requiring compact panel-mount installations.

Q: Can these connectors be used in applications requiring USB 3.0 or higher?

A: No. Both MUSBC51101 and MUSBC511N1 are specified for USB 2.0 compliance only. Applications requiring USB 3.0 or higher data rates require different connector designs.

Q: What is the significance of the IP67 rating?

A: IP67 indicates dust-tight and waterproof protection. The connector is sealed against dust ingress and can withstand temporary immersion in water up to 1 meter depth for 30 minutes. This rating is suitable for industrial and outdoor applications.

Q: Are these parts suitable for high-temperature applications?

A: Yes. Both parts are rated for continuous operation from -40°C to 105°C. This temperature range covers most industrial and commercial applications. Specific application requirements should be verified against the operating environment.

Q: What is the difference between the part numbers MUSBC51101 and MUSBC511N1?

A: The part numbers represent variants within the MUSB series. Both parts share the base product number MUSBC and are functionally equivalent. The suffix variation (51101 vs. 511N1) indicates manufacturing or packaging variants, but all electrical and mechanical specifications remain identical.

Q: Is RoHS compliance important for my application?

A: RoHS compliance is mandatory for products sold in the European Union and many other regulated markets. Both MUSBC51101 and MUSBC511N1 are RoHS compliant, making them suitable for regulated applications without additional material certifications.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. These parts have unlimited shelf life and do not require special moisture-controlled storage or handling procedures. They can be stored under standard warehouse conditions.
