LCMB300-12-6 Equivalent & Substitute Parts

Part Overview

The LCMB300-12-6 is a ring terminal connector manufactured by Panduit Corp, designed for M12 stud applications with 300mm² wire gauge capacity. This component is classified as a flat-sided, tubular battery lug terminal with crimp termination. The part is currently listed as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity for applications requiring this terminal specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LCMB300-12-6 is determined by the following critical parameters that must remain constant across equivalent parts:

Fixed Parameters (Non-Negotiable):

• Wire gauge capacity: 300mm²
• Terminal type: Flat-sided, tubular battery lug configuration
• Termination method: Crimp
• Contact material: Copper with tin finish
• Insulation type: Non-insulated
• Mounting configuration: Free hanging (in-line)

Variable Parameters (Allowable Differences):

• Stud/tab size: The LCMB300-12-6 specifies M12 stud connection; substitutes may accommodate different stud sizes (M16, M20, etc.) depending on application requirements
• Overall length and width dimensions: Physical envelope may vary with stud size changes
• Product status: Active alternatives are preferred over obsolete designations
• Series designation: Different series names (LCMB vs. LCMA) are acceptable if core electrical and mechanical specifications align

The LCMA300-16-5 qualifies as a substitute based on matching wire gauge, terminal type, contact material, finish, and termination method, with the primary difference being the M16 stud accommodation instead of M12.

Parameter Comparison

Engineering Selection Recommendations

The LCMA300-16-5 is the identified substitute for the obsolete LCMB300-12-6. Selection of this alternative is supported by the following engineering criteria:

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental directives.

Electrical Equivalence: Identical wire gauge capacity (300mm²), contact material (copper), and contact finish (tin) ensure electrical performance parity for high-current applications typical of battery lug terminals.

Mechanical Compatibility: Matching terminal type, thickness, and width dimensions provide consistent mechanical interface characteristics. The primary design difference is the stud size accommodation (M16 versus M12), which requires verification against the application's fastening specification.

Supply Chain Status: The LCMA300-16-5 is listed as active with 798 pieces in stock, providing immediate availability compared to the obsolete LCMB300-12-6 status.

Series Transition: The shift from LCMB series to Pan-Lug™ series (LCMA) reflects Panduit's product line evolution while maintaining core terminal functionality and performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the LCMA300-16-5 directly replace the LCMB300-12-6 in all applications?

A: Direct replacement depends on the stud size requirement of the target application. The LCMA300-16-5 accommodates M16 studs, while the LCMB300-12-6 accommodates M12 studs. If the application fastening specification requires M12, the M16 alternative is not compatible. If the application can accommodate M16 studs, the substitute is functionally equivalent.

Q: Are there electrical performance differences between these two terminals?

A: No. Both terminals share identical wire gauge capacity (300mm²), copper contact material, and tin finish. Electrical performance for current-carrying capacity and contact resistance is equivalent.

Q: What is the significance of the length difference between these parts?

A: The length difference (4.827" versus 3.720") is a direct result of the different stud sizes (M12 versus M16). The M16 stud requires less overall terminal length to achieve the same mechanical engagement. This dimensional change does not affect electrical performance but must be considered in mechanical assembly and clearance planning.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the LCMB300-12-6 and LCMA300-16-5 are ROHS3 compliant and REACH unaffected, meeting current environmental directive requirements.

Q: Why is the LCMB300-12-6 listed as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions based on market demand, product line consolidation, or transition to newer series designations. The LCMA series represents Panduit's current active product line for equivalent terminal applications.

Q: What packaging format is available for the LCMA300-16-5?

A: The LCMA300-16-5 is supplied in bulk packaging, which may differ from the original part's packaging specification. Bulk packaging is standard for high-volume terminal applications.

Q: Are there any other Panduit terminals with 300mm² wire gauge capacity?

A: Based on the provided substitute information, the LCMA300-16-5 is the identified equivalent. Additional alternatives may exist within Panduit's product portfolio but are not included in this reference documentation.
