LAPP 79042200 Hood Connector Top Entry M25 HA10 Equivalent & Substitute Parts

Part Overview

The LAPP 79042200 is an EPIC® HB series heavy duty connector hood designed for top entry applications with M25 thread size. This accessory component provides dust-tight and water-resistant sealing (IP65) in industrial environments with operating temperatures from -40°C to 100°C. The connector features a locking clip mechanism on the base bottom and is constructed from powder-coated aluminum alloy housing.

This part is currently active in production with 1,021 units in stock. Substitute parts are identified to support applications requiring equivalent functional performance, alternative sourcing, or inventory management in heavy duty connector installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LAPP 79042200 is determined by the following critical parameters:

Thread Size Compatibility: M25 thread size is the primary mechanical interface requirement. Substitute parts must maintain M25 threading to ensure proper installation in existing mounting infrastructure.

Ingress Protection Rating: IP65 classification (dust tight, water resistant) establishes the environmental sealing performance baseline. Substitute parts must meet or exceed this rating to maintain equivalent environmental protection.

Housing Material and Finish: Aluminum alloy construction with powder coating provides corrosion resistance and mechanical durability. Substitute parts utilizing equivalent materials and finishes ensure comparable service life and environmental performance.

Connector Type and Function: Hood connectors serve as protective covers and coupling interfaces in heavy duty connector systems. Substitute parts must function within the same connector ecosystem.

Operating Temperature Range: The -40°C to 100°C operating window defines thermal performance requirements. Substitute parts must support equivalent or extended temperature ranges.

The identified substitute part (HARTING 19300100756) shares the critical M25 thread size, IP65 ingress protection, aluminum alloy housing with powder coating, and overlapping operating temperature capability, establishing functional equivalence within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - LAPP 79042200: Maintain this part number for applications requiring EPIC® HB series integration, top entry configuration, and the specified -40°C to 100°C operating range. Active production status and current inventory (1,021 units) support immediate availability.

Substitute Selection - HARTING 19300100756: This part provides functional equivalence for M25 thread interface and IP65 environmental protection. The substitute operates across an extended temperature range (-40°C to 125°C), accommodating higher thermal environments. However, the bottom entry style and Han® B series designation indicate integration into a different connector ecosystem. Selection of this substitute requires verification of mechanical compatibility with existing mounting and coupling interfaces.

Both parts maintain active product status and comply with applicable trade classifications (ECCN: EAR99, HTSUS: 8538.90.8180). The HARTING substitute includes RoHS3 compliance and REACH unaffected status documentation.

Frequently Asked Questions (FAQ)

Q: What determines whether HARTING 19300100756 can substitute for LAPP 79042200?

A: Substitution is valid when the following parameters align: M25 thread size, IP65 ingress protection rating, aluminum alloy housing with powder coating, and compatible operating temperature range. Both parts meet these criteria. However, the entry style difference (top vs. bottom) and series difference (EPIC® HB vs. Han® B) require verification that the substitute integrates properly with existing connector assemblies and mounting hardware.

Q: Why does the HARTING substitute have a different height dimension?

A: The HARTING 19300100756 measures 74.40 mm in height compared to 54.80 mm for the LAPP part. This dimensional difference reflects the bottom entry configuration and different internal locking clip placement (hood top vs. base bottom). Physical space constraints in the installation environment must be evaluated before substitution.

Q: Are both parts suitable for the same environmental conditions?

A: Both parts provide IP65 dust-tight and water-resistant protection. The HARTING substitute supports an extended operating temperature range (-40°C to 125°C) compared to the LAPP part (-40°C to 100°C). For applications within the LAPP temperature window, both parts deliver equivalent environmental performance.

Q: What is the significance of the different connector type designations?

A: The LAPP part is designated as a "Hood" connector, while the HARTING part is designated as "Hood - Coupling." This indicates the HARTING part includes integrated coupling functionality for cable-to-cable connections. The functional difference may affect compatibility with existing connector pin and socket configurations.

Q: Can these parts be used interchangeably in existing installations?

A: Direct interchangeability requires that the installation accommodates the bottom entry style, different height dimension, and Han® B series coupling interface. The M25 thread size and IP65 rating provide mechanical and environmental compatibility, but connector series integration must be confirmed before substitution.

Q: What packaging and inventory considerations apply?

A: Both parts are supplied in bulk packaging. LAPP 79042200 has 1,021 units in current stock. HARTING 19300100756 has 924 units available. Bulk packaging requires appropriate handling and storage procedures for heavy duty connector components.
