MUSBR439330 Equivalent & Substitute Parts

Part Overview

The MUSBR439330 is a stacked USB 3.0 Type-A receptacle connector manufactured by Amphenol ICC. This 18-position panel mount connector features right-angle through-hole termination with dual ports, designed for applications requiring high-speed USB 3.2 Gen 1 data transfer with robust environmental sealing. The connector is actively produced and maintains full RoHS compliance with UL94 V-0 flammability rating. Substitute parts are identified when electrical specifications, mechanical mounting characteristics, and environmental ratings remain functionally equivalent across the connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MUSBR439330 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: USB-A stacked receptacle with 18 contacts
• USB Protocol Support: USB 3.2 Gen 1 specification compliance
• Mounting Geometry: Panel mount, through-hole, right-angle orientation with flange and horizontal mounting feature
• Electrical Performance: Dual-port configuration with 0.25A and 1.8A current ratings
• Environmental Compliance: IP67 ingress protection, operating temperature -40°C to 105°C, UL94 V-0 flammability rating
• Material & Finish: Shielded construction with gold-plated contacts and stainless steel shielding
• Regulatory Status: RoHS compliance and EAR99 export classification

The MUSBR-4193-M0 meets all these criteria and is classified as a parametric equivalent within the MUSBR series.

Parameter Comparison

Engineering Selection Recommendations

Both the MUSBR439330 and MUSBR-4193-M0 are active production components from Amphenol ICC with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory Availability: MUSBR439330 has 769 units in stock; MUSBR-4193-M0 has 1268 units in stock
• Regulatory Compliance: Both parts maintain RoHS compliance and UL94 V-0 flammability certification
• Supply Chain Continuity: Both parts share the same MUSBR base product number and are classified under identical ECCN and HTSUS codes, ensuring consistent procurement and logistics handling
• Moisture Sensitivity: MUSBR439330 is rated MSL 1 (Unlimited); MUSBR-4193-M0 is Not Applicable. Both are suitable for standard storage and handling conditions

Frequently Asked Questions (FAQ)

Q: Can MUSBR-4193-M0 be used as a direct replacement for MUSBR439330?

A: Yes. Both connectors are parametric equivalents with identical contact count, USB 3.2 Gen 1 protocol support, mounting configuration, current ratings, environmental protection, and material specifications. They are interchangeable at the circuit board level.

Q: Are there differences in mating cycle ratings between these parts?

A: The MUSBR439330 specifies 1500 mating cycles. The MUSBR-4193-M0 does not provide a mating cycle specification in the available data. For applications with defined mating cycle requirements, the MUSBR439330 provides explicit performance documentation.

Q: Do both connectors support the same USB data rates?

A: Yes. Both connectors comply with USB 3.2 Gen 1 (also designated USB 3.1 Gen 1 or Superspeed USB 3.0) specification, supporting equivalent data transfer rates and protocol features.

Q: What is the significance of the stacked configuration?

A: The stacked configuration indicates dual-port design within a single connector footprint. Both parts feature 2 ports and are suitable for applications requiring multiple USB 3.0 connections in a compact panel-mount form factor.

Q: Are these connectors suitable for harsh environmental conditions?

A: Yes. Both connectors feature IP67 ingress protection (dust tight and waterproof), operate across -40°C to 105°C temperature range, and incorporate shielded construction with stainless steel shielding for environmental robustness.

Q: What is the through-hole termination specification?

A: Both connectors use solder termination with through-hole mounting. The right-angle orientation with flange and horizontal mounting feature provides mechanical stability for panel-mount applications.
