Substitute Part Grouping Explanation

Substitution of the UB-MC5ABR3-M04-4S-TB-1 NMP is based on the following critical parameters:

• Connector Type: USB micro AB receptacle configuration must be maintained
• Contact Count: 5-position requirement is non-negotiable
• Gender: Receptacle type only
• Mounting Configuration: Board cutout and surface mount capability
• Electrical Ratings: Operating temperature range of -30°C to 85°C, voltage rating of 30VAC/DC minimum, and current handling capacity
• Termination Method: Solder termination required
• Mechanical Durability: Mating cycle rating of 10,000 cycles minimum
• Environmental Compliance: UL94 V-0 flammability rating and MSL 1 classification

The substitute part 0476540001 (Molex 47654 series) meets these core substitution criteria while offering active product status and enhanced availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0476540001 connector serves as a direct functional substitute for the obsolete JST UB-MC5ABR3-M04-4S-TB-1 NMP. Both connectors maintain identical core electrical and mechanical specifications across operating temperature, voltage rating, current capacity, and mating cycle durability. The substitute part offers the advantage of active product status, ensuring long-term availability and supply chain continuity.

The Molex part incorporates shielding, which provides enhanced electromagnetic interference (EMI) protection compared to the unshielded original design. This represents an engineering improvement rather than a limitation. The substitute also demonstrates ROHS3 compliance, meeting current environmental regulatory requirements.

Mounting configuration differences exist: the Molex part supports board edge, cutout, surface mount, through hole, and right angle options, providing greater design flexibility than the original board cutout and surface mount configuration. These additional mounting options do not preclude use in applications designed for the original part's mounting type.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0476540001 directly replace the JST UB-MC5ABR3-M04-4S-TB-1 NMP in existing designs?

A: Yes. Both connectors share identical USB micro AB receptacle configuration, 5-position contact count, operating temperature range (-30°C to 85°C), voltage rating (30VAC/DC), current capacity (1A, 1.8A), mating cycle rating (10,000), and solder termination method. The substitute meets all core electrical and mechanical requirements.

Q: What is the significance of the shielding difference?

A: The original JST part is unshielded, while the Molex substitute is shielded. Shielding provides EMI protection and represents a design enhancement. Applications requiring unshielded connectors should evaluate whether shielding introduces any mechanical or electrical constraints specific to their design.

Q: Does the Molex part's ROHS3 compliance affect compatibility?

A: No. ROHS3 compliance indicates adherence to environmental regulations and does not impact electrical or mechanical compatibility. This certification supports regulatory compliance for end products.

Q: Are there current rating differences to consider?

A: The original JST part supports 0.5A, 1A, and 1.8A ratings. The Molex substitute supports 1A and 1.8A ratings. Applications requiring 0.5A operation should confirm that the 1A minimum rating of the substitute meets design requirements.

Q: What mounting configuration should be selected for the Molex part?

A: The Molex 0476540001 supports multiple mounting options including board cutout and surface mount, matching the original part's configuration. Additional mounting options (board edge, through hole, right angle) are available but not required for direct substitution.

Q: How does product status affect part selection?

A: The original JST part is obsolete, creating supply and support risks. The Molex substitute maintains active product status, ensuring availability, technical support, and production continuity for new designs and ongoing maintenance applications.
