Parameter Comparison

Engineering Selection Recommendations

Both MUSBC51105 and MUSBC511N1 are active production components from Amphenol ICC (Commercial Products) with identical electrical, mechanical, and compliance specifications. Selection between these parts is based on availability and procurement requirements:

MUSBC51105: 1003 pieces in stock. Primary selection for immediate procurement needs.

MUSBC511N1: 1063 pieces in stock. Alternative selection offering equivalent functionality with higher current inventory levels.

Both parts carry RoHS compliance certification and UL94 V-0 flammability rating, confirming suitability for regulated applications. The IP67 ingress protection rating qualifies both connectors for sealed, waterproof panel mount installations. Operating temperature range of -40°C to 105°C supports industrial and commercial deployment environments. Gold contact finish and shielded design ensure signal integrity and corrosion resistance across the 1500 mating cycle lifecycle.

No technical differentiation exists between these parts. Selection is determined by supply chain availability and inventory management priorities.

Frequently Asked Questions (FAQ)

Q: Can MUSBC511N1 be used as a direct replacement for MUSBC51105 in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (USB 2.0, 1.5A current rating, 8-contact receptacle), mechanical configuration (panel mount, through-hole, flange vertical), and environmental ratings (IP67, -40°C to 105°C operating range). No design modification is required.

Q: Are there differences in connector footprint or PCB mounting between these parts?

A: No. Both parts share identical mounting specifications: Panel Mount, Through Hole configuration with Flange, Vertical orientation. PCB layout and hole patterns are equivalent.

Q: Do both parts meet the same compliance and certification standards?

A: Yes. Both MUSBC51105 and MUSBC511N1 are RoHS Compliant, carry UL94 V-0 flammability rating, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the significance of the IP67 rating for these connectors?

A: IP67 rating indicates dust-tight and waterproof performance. These connectors are sealed against ingress of dust and water immersion up to 1 meter depth for 30 minutes, qualifying them for harsh environmental applications.

Q: Are there any differences in contact finish or shielding between the two parts?

A: No. Both parts feature gold contact finish and shielded design, ensuring equivalent signal integrity, corrosion resistance, and electromagnetic interference protection.

Q: What is the Moisture Sensitivity Level (MSL) rating, and why is it relevant?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. Standard storage conditions apply without desiccant requirements.

Q: Can these connectors support USB 3.0 or higher specifications?

A: No. Both parts are specified for USB 2.0 only. They are not compatible with USB 3.0 or higher-speed protocols.

Q: What is the expected lifespan based on mating cycle rating?

A: Both parts are rated for 1500 mating cycles. This represents the mechanical durability limit for connector insertion and removal operations under normal operating conditions.
