LCMB35-12-Q Ring Terminal Connector Equivalent & Substitute Parts

Part Overview

The LCMB35-12-Q is a ring terminal connector manufactured by Panduit Corp, designed for M12 stud applications with 35mm² 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 equivalent alternatives for ongoing applications requiring ring terminal connectors in this category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LCMB35-12-Q is determined by the following critical parameters that must remain constant across equivalent parts:

Fixed Parameters (Non-Negotiable):

• Wire gauge: 35mm²
• Terminal type: Flat-sided, tubular (battery lugs)
• Termination method: Crimp
• Insulation: Non-Insulated
• Contact material: Copper
• Contact finish: Tin
• Mounting type: Free hanging (in-line)
• Manufacturer: Panduit Corp
• Base series: LCMB

Variable Parameters (Substitution Basis):

• Stud/tab size: M12 (main part) versus M10 (substitute)
• Physical dimensions: Thickness, width, and length vary with stud size
• Product status: Obsolete (main part) versus active (substitute)

The LCMB35-10-Q qualifies as a substitute because it maintains all fixed parameters while accommodating applications requiring M10 stud connections instead of M12. This substitution is valid only when the application's stud size requirement can be modified to M10.

Engineering Selection Recommendations

LCMB35-12-Q (Obsolete Status): The main part is classified as obsolete. While inventory remains available (1124 pieces), long-term supply continuity cannot be assured. This part maintains ROHS3 compliance and REACH unaffected status.

LCMB35-10-Q (Active Status): This substitute part is currently active in production, ensuring ongoing availability and supply chain stability. It maintains identical compliance certifications (ROHS3 compliant, REACH unaffected) and shares all core electrical and material specifications with the main part. The primary difference is the stud size reduction from M12 to M10, which requires application-level compatibility verification.

Selection between these parts depends on whether the application's stud connection point can accommodate M10 fasteners. If M12 stud compatibility is mandatory, the LCMB35-12-Q remains the only option within this product family. If M10 studs are acceptable, the LCMB35-10-Q provides superior long-term supply assurance due to its active product status.

Frequently Asked Questions (FAQ)

Q: Can LCMB35-10-Q directly replace LCMB35-12-Q in all applications?

A: No. The LCMB35-10-Q features an M10 stud connection, while the LCMB35-12-Q uses an M12 stud. Direct substitution is only possible if the application's stud fastener can be changed from M12 to M10. All other electrical and mechanical characteristics are equivalent.

Q: What wire gauge capacity do both parts support?

A: Both the LCMB35-12-Q and LCMB35-10-Q support 35mm² wire gauge. Wire gauge capacity is identical between the two parts.

Q: Are there dimensional differences between these parts?

A: Yes. The LCMB35-10-Q has different overall dimensions due to the smaller M10 stud size. Thickness increases from 0.059" to 0.081", width decreases from 0.846" to 0.610", and length decreases from 2.492" to 2.256". These dimensional changes are proportional to the stud size reduction.

Q: Do both parts meet the same compliance standards?

A: Yes. Both LCMB35-12-Q and LCMB35-10-Q are ROHS3 compliant and REACH unaffected. Compliance certifications are identical.

Q: Why is LCMB35-12-Q listed as obsolete?

A: The LCMB35-12-Q is classified as obsolete, indicating it is no longer in active production. However, inventory remains available. The LCMB35-10-Q, as an active product, represents the current production alternative within the LCMB series for 35mm² applications.

Q: What is the contact material and finish for both parts?

A: Both parts feature copper contacts with tin finish. Contact material and finish specifications are identical.

Q: Are both parts non-insulated?

A: Yes. Both the LCMB35-12-Q and LCMB35-10-Q are non-insulated ring terminal connectors.

Q: What termination method is used for these parts?

A: Both parts use crimp termination. The termination method is identical between the two parts.
