Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCR-B-MPLUG-CS8 is determined by the following critical parameters:

• Connector Type & Gender: USB - micro B Plug configuration (5 position)
• Mounting Configuration: Surface mount, right-angle, horizontal orientation
• Electrical Ratings: Current capacity and voltage rating compatibility
• Environmental Compliance: RoHS3 compliance and operating temperature range
• Termination Method: Solder-based connection

The Molex 1051640001 is identified as a substitute based on matching connector type (USB - micro B), contact count (5 positions), mounting style (surface mount, right angle), and compliance certifications (RoHS3, UL94 V-0). However, this substitute operates as a receptacle rather than a plug, and exhibits different electrical and thermal specifications that must be evaluated for application compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MCR-B-MPLUG-CS8 is obsolete; therefore, component replacement is necessary for new production or design revisions. The Molex 1051640001 provides active product status with ROHS3 compliance and UL94 V-0 flammability rating, matching the compliance profile of the original component.

Selection of the 1051640001 requires verification that the receptacle configuration aligns with the application's connector pairing strategy. The substitute exhibits higher current capacity (1A, 1.8A versus 0.5A) and reduced operating temperature range (-35°C ~ 85°C versus -55°C ~ 105°C), which may impact suitability for extreme temperature environments. The voltage rating difference (30VAC versus 150V) must be evaluated against application requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 1051640001 directly replace the MCR-B-MPLUG-CS8?

A: Direct replacement is not possible due to gender mismatch. The MCR-B-MPLUG-CS8 is a plug connector, while the 1051640001 is a receptacle. These components are designed to mate with each other, not to substitute for one another in the same circuit position. Substitution requires that the mating connector in the application also be replaced with a compatible counterpart.

Q: What are the critical differences in electrical ratings?

A: The MCR-B-MPLUG-CS8 is rated for 0.5A at 150V, while the 1051640001 is rated for 1A or 1.8A at 30VAC. Applications requiring the higher voltage rating of the original component cannot use the substitute without circuit redesign.

Q: Are both connectors RoHS3 compliant?

A: Yes, both the MCR-B-MPLUG-CS8 and the Molex 1051640001 are ROHS3 compliant with UL94 V-0 flammability ratings, meeting equivalent environmental and safety standards.

Q: What is the operating temperature difference?

A: The MCR-B-MPLUG-CS8 operates from -55°C to 105°C, while the 1051640001 operates from -35°C to 85°C. Applications requiring extended low-temperature operation below -35°C or high-temperature operation above 85°C may not be suitable for the substitute.

Q: Does the Molex 1051640001 support through-hole mounting?

A: Yes, the 1051640001 supports both surface mount and through-hole mounting configurations, providing additional design flexibility compared to the surface-mount-only MCR-B-MPLUG-CS8.
