Substitute Part Grouping Explanation

All substitute parts (MUSBRA11145, MUSBRA111M5, MUSBRA111R5) are parametric equivalents of the MUSBRA111R1. Substitution is based on strict equivalence across the following critical parameters:

Connector Type: USB-A (USB TYPE-A) Receptacle
Specifications: USB 2.0
Number of Contacts: 4
Mounting Configuration: Panel Mount, Through Hole, Right Angle
Electrical Performance: 1.5A current rating, 1500 mating cycles
Environmental Protection: IP67 rating
Thermal Range: -40°C to 105°C
Compliance: RoHS Compliant, UL94 V-0, MSL Level 1
Material: Shielded with gold-plated contacts, steel/stainless steel shell
Termination: Solder

All substitute parts maintain identical functional, electrical, mechanical, and environmental specifications. Differences in part number designation reflect internal manufacturing variations within the MUSBR series that do not affect interchangeability.

MUSBRA11145: Highest inventory level (1205 units)
MUSBRA111R5: Strong availability (1092 units)
MUSBRA111R1: Adequate stock (804 units)
MUSBRA111M5: Lower availability (701 units)

All parts meet RoHS compliance, UL94 V-0 flammability standards, and MSL Level 1 moisture sensitivity requirements, making them suitable for equivalent circuit board assembly and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Are these substitute parts electrically identical to the MUSBRA111R1? A: Yes. All substitute parts deliver identical USB 2.0 performance with 1.5A current capacity, 1500 mating cycles, and the same -40°C to 105°C operating range.

Q: What determines compatibility between MUSBRA111R1 and its substitutes? A: Compatibility is determined by matching connector type (USB-A Receptacle), contact count (4), mounting configuration (panel mount, through-hole, right-angle), termination method (solder), and electrical ratings (1.5A, USB 2.0).

Q: Can these parts be used interchangeably on the same printed circuit board? A: Yes. All parts feature identical panel mount, through-hole, right-angle mounting with solder termination, ensuring direct board-level compatibility without layout modification.

Q: Are there any environmental or compliance differences? A: No. All parts are IP67-rated, shielded with steel/stainless steel shells, gold-plated contacts, RoHS-compliant, UL94 V-0 rated, and classified as MSL Level 1.

Q: How do the part number suffixes differ? A: The suffix variations (R1, 45, M5, R5) reflect internal manufacturing designations within the MUSBR series but do not affect electrical, mechanical, or environmental performance.

Q: What is the basis for choosing between substitute options? A: Selection criteria include supply chain availability, inventory levels, and lead times. All parts are functionally identical for engineering purposes.
