LAPP 19429200 Equivalent & Substitute Parts Reference

Part Overview

The LAPP 19429200 is a heavy-duty connector hood assembly designed for coupling applications with bottom entry configuration. This component functions as a protective housing and coupling interface for the EPIC® H-A series connector system. The part is classified as Active product status with 817 units in current inventory stock.

Substitute parts are identified when equivalent functional performance can be achieved through alternative manufacturers while maintaining compatibility with the core mechanical and electrical parameters of the original specification. The HARTING 19200030727 represents a functionally similar alternative within the heavy-duty connector hood category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LAPP 19429200 is determined by strict alignment of the following parameters:

Critical Compatibility Parameters:

• Connector Type: Hood - Coupling (both parts)
• Thread Size: M20 (both parts)
• Size Designation: A3 / 3A (equivalent sizing)
• Lock Location: Locking Clip (1) on Hood Top (both parts)
• Style: Bottom Entry configuration

Application-Dependent Parameters:

• Ingress Protection: LAPP 19429200 specifies IP65 (Dust Tight, Water Resistant); HARTING 19200030727 specifies IP44. Selection depends on environmental exposure requirements.
• Operating Temperature: LAPP operates -40°C to 100°C; HARTING operates -40°C to 125°C. Selection depends on thermal environment.
• Housing Material: LAPP uses Thermoplastic; HARTING uses Polycarbonate (PC). Both materials are suitable for heavy-duty connector applications.

The HARTING 19200030727 qualifies as a substitute based on matching critical mechanical and functional parameters. However, the reduced ingress protection rating (IP44 vs. IP65) requires evaluation against specific application environmental conditions.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (LAPP 19429200): Select the LAPP 19429200 when IP65 ingress protection (Dust Tight, Water Resistant) is required for the application. This part is Active status with established supply (817 units in stock). The EPIC® H-A series designation provides integration with LAPP's connector ecosystem.

Substitute Part Selection (HARTING 19200030727): The HARTING 19200030727 qualifies as a substitute when:

• IP44 ingress protection is acceptable for the application environment
• Extended operating temperature range (-40°C to 125°C) provides advantage over the primary part's -40°C to 100°C range
• Polycarbonate housing material meets material compatibility requirements
• Integration with Han® A series connector system is acceptable

Both parts carry Active product status and EAR99 ECCN classification. The HARTING part includes RoHS3 compliance and REACH Unaffected status documentation.

Critical Constraint: The reduction in ingress protection from IP65 to IP44 represents the primary technical difference. Applications requiring dust-tight and water-resistant sealing must retain the LAPP 19429200. Applications with less stringent environmental exposure may utilize the HARTING substitute.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 19200030727 directly replace the LAPP 19429200 in all applications?

A: No. While both parts share critical mechanical parameters (M20 thread, A3/3A size, bottom entry style, locking clip configuration), the HARTING part provides IP44 ingress protection versus the LAPP part's IP65 rating. Substitution is valid only when IP44 protection meets application environmental requirements.

Q: What does the difference between IP65 and IP44 mean for connector hood selection?

A: IP65 provides complete dust protection and water resistance against low-pressure jets from any direction. IP44 provides splash protection and limited dust ingress. Applications exposed to high-pressure water spray, submersion, or heavy dust environments require IP65. Applications in controlled indoor environments may accept IP44.

Q: Are the A3 and 3A size designations equivalent?

A: Yes. The LAPP A3 designation and HARTING 3A designation represent equivalent connector sizes within their respective series (EPIC® H-A and Han® A). Both accommodate the same M20 thread interface and locking clip configuration.

Q: Does the operating temperature range difference affect substitution eligibility?

A: The HARTING part's extended range (-40°C to 125°C versus -40°C to 100°C) provides additional thermal capability but does not restrict substitution. If the application operates within the LAPP part's -40°C to 100°C range, both parts are suitable. If the application requires operation above 100°C, only the HARTING part qualifies.

Q: What is the significance of the different housing materials (Thermoplastic vs. Polycarbonate)?

A: Both materials are suitable for heavy-duty connector applications. Polycarbonate (PC) offers superior impact resistance and optical clarity. Thermoplastic provides cost efficiency and adequate mechanical properties. Material selection depends on mechanical stress and environmental exposure requirements specific to the application.

Q: Are both parts currently available in inventory?

A: Yes. The LAPP 19429200 has 817 units in stock. The HARTING 19200030727 has 815 units in stock. Both parts maintain Active product status with established supply chains.

Q: What compliance certifications apply to these parts?

A: Both parts carry EAR99 ECCN classification. The HARTING 19200030727 includes additional RoHS3 compliance and REACH Unaffected status documentation. Verify compliance requirements for your specific application and regulatory jurisdiction.
