Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MUSBD51101 are qualified 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:

Electrical Parameters: Current Rating (1.5A), USB 2.0 specification compliance, 4-position contact configuration, shielded design, and gold contact finish.

Mechanical Parameters: USB-B connector type, receptacle gender, panel mount through-hole mounting, vertical flange orientation, board lock and cover features, and solder termination.

Environmental & Compliance Parameters: IP67 ingress protection rating, operating temperature range of -40°C to 105°C, 1500 mating cycle rating, UL94 V-0 flammability rating, and RoHS compliance.

Material Specifications: Copper alloy shell/shielding material and white insulation color.

All substitute parts listed maintain 100% parametric equivalence across these criteria, ensuring direct interchangeability in circuit design and PCB layout without modification.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—MUSBD51101, MUSBD511N1, and MUSBD511N5—are functionally equivalent and interchangeable for USB-B receptacle connector applications. Selection between these parts should be based on inventory availability and supply chain considerations rather than technical performance differences.

MUSBD51101 is the primary part number with 831 units in stock inventory.

MUSBD511N1 provides an alternative source with higher inventory availability at 1253 units in stock.

MUSBD511N5 offers a third sourcing option with 845 units in stock.

All three parts maintain identical electrical performance, mechanical compatibility, environmental ratings, and regulatory compliance. Each part is RoHS compliant, carries UL94 V-0 flammability certification, and meets IP67 ingress protection requirements. The choice between these part numbers does not affect circuit design, PCB layout, or system performance.

Frequently Asked Questions (FAQ)

Q: Can MUSBD511N1 and MUSBD511N5 be used as direct replacements for MUSBD51101?
