LCAX750-12H-3 Equivalent & Substitute Parts

Part Overview

The LCAX750-12H-3 is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 750MCM (kcmil) wire gauge applications with a 1/2 stud configuration. This component is classified as obsolete, indicating it is no longer in active production. The terminal features a crimp barrel termination method, electro-tin contact finish, and copper contact material suitable for high-amperage electrical connections.

Due to its obsolete status, identifying equivalent substitute parts is necessary for ongoing maintenance, repair, and new installation requirements where this specific model is specified or required for compatibility with existing systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LCAX750-12H-3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Wire gauge: 750MCM (kcmil)
• Contact material: Copper
• Contact finish: Electro-Tin
• Termination method: Crimp, Barrel

Mechanical Parameters:

• Stud/Tab size: 1/2 Stud
• Terminal type: Rectangular Tongue
• Terminal style: Single Stud Hole
• Ring ID diameter: 0.530" (13.46mm)
• Barrel ID diameter: 1.170" (29.72mm)
• Barrel OD diameter: 1.500" (38.10mm)
• Tab thickness: 0.320" (8.13mm)
• Width - Outer Edges: 2.170" (55.12mm)

Compliance Parameters:

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99

Substitute parts must match all electrical and mechanical parameters listed above. Variations in mounting type or overall length do not affect functional substitution when all other parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

The LCAX750-12-3 is the direct functional equivalent to the LCAX750-12H-3. All critical electrical and mechanical parameters are identical, including wire gauge, stud size, terminal geometry, contact material, contact finish, and termination method.

Product Status Consideration: The LCAX750-12H-3 is obsolete, while the LCAX750-12-3 is active. The active status of LCAX750-12-3 ensures ongoing availability and manufacturing support.

Compliance Alignment: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and EAR99 ECCN classification, confirming regulatory equivalence for applications requiring these certifications.

Functional Differences: The LCAX750-12-3 differs in mounting type (standard Free Hanging In-Line versus 45° Angle configuration) and includes a specified overall length of 3.940" (100.08mm). These differences do not affect electrical or mechanical compatibility in applications where the standard mounting orientation is acceptable.

For applications requiring the specific 45° angle mounting configuration of the LCAX750-12H-3, mounting type must be evaluated against system requirements before substitution.

Frequently Asked Questions (FAQ)

Q: Can LCAX750-12-3 be used as a direct replacement for LCAX750-12H-3?

A: Yes. The LCAX750-12-3 is electrically and mechanically equivalent to the LCAX750-12H-3 across all critical parameters: wire gauge (750MCM), stud size (1/2), terminal type (Rectangular Tongue), contact material (Copper), contact finish (Electro-Tin), and termination method (Crimp, Barrel). Both parts are ROHS3 compliant and REACH unaffected.

Q: What is the primary difference between these two parts?

A: The LCAX750-12H-3 features a 45° angle mounting configuration, while the LCAX750-12-3 uses standard Free Hanging In-Line mounting. The LCAX750-12-3 also specifies an overall length of 3.940" (100.08mm). The LCAX750-12H-3 is obsolete; the LCAX750-12-3 is active production.

Q: Does the mounting type difference affect electrical performance?

A: No. The mounting type difference (45° angle versus standard in-line) does not affect electrical performance, current capacity, or contact integrity. Selection depends on physical installation requirements and spatial constraints within the application.

Q: Are both parts compliant with RoHS3 and REACH regulations?

A: Yes. Both LCAX750-12H-3 and LCAX750-12-3 are ROHS3 compliant and REACH unaffected, confirming regulatory equivalence for applications requiring these certifications.

Q: What wire gauge do these terminals accommodate?

A: Both terminals are rated for 750MCM (kcmil) wire gauge with crimp barrel termination and 1/2 stud connection.

Q: Why is the LCAX750-12H-3 listed as obsolete?

A: The LCAX750-12H-3 is no longer in active production. The LCAX750-12-3 serves as the current production equivalent, offering identical electrical and mechanical specifications with ongoing manufacturing support.

Q: Can I use LCAX750-12-3 in existing installations designed for LCAX750-12H-3?

A: Yes, provided the standard Free Hanging In-Line mounting orientation is compatible with your installation. If the 45° angle mounting of the original LCAX750-12H-3 is critical to your application, mounting configuration must be evaluated before substitution.

Q: What is the contact material and finish for these terminals?

A: Both terminals feature copper contact material with electro-tin finish, providing corrosion resistance and reliable electrical conductivity for high-amperage applications.
