LAPP 19427300 Equivalent & Substitute Parts Reference

Part Overview

The LAPP 19427300 is an EPIC® H-A series heavy duty connector hood designed for side entry applications with M20 thread size. This component provides IP65 ingress protection (dust tight, water resistant) and operates across an extended temperature range of -40°C to 125°C. The connector features a zinc die cast housing with powder coating and employs a locking clip mechanism on the base bottom for secure fastening.

This part is classified as Active product status with 699 units currently in stock. Equivalent and substitute parts are identified to support procurement flexibility, supply chain continuity, and application-specific requirements where alternative ingress protection ratings or housing materials may be acceptable within system design parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LAPP 19427300 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector Type: Hood
• Style: Side Entry
• Thread Size: M20
• Lock Location: Locking Clip (1) on Base Bottom
• Operating Temperature Range: -40°C to 125°C (minimum requirement)

Secondary Compatibility Criteria:

• Ingress Protection Rating: IP44 or higher (IP65 is preferred; IP44 acceptable for less demanding environments)
• Housing Material: Zinc Die Cast or Polycarbonate (PC)
• Size Designation: HA3/4 or equivalent 3A classification

The HARTING 19200030627 qualifies as a substitute part based on matching primary criteria (hood connector, side entry, M20 thread, identical locking mechanism, and identical operating temperature range). The substitute maintains functional compatibility despite differences in ingress protection rating (IP44 versus IP65) and housing material (polycarbonate versus zinc die cast).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (LAPP 19427300): Select the LAPP 19427300 for applications requiring IP65 ingress protection in environments with high dust and water exposure. The zinc die cast housing with powder coating provides enhanced corrosion resistance. This part is recommended as the first choice for demanding industrial environments and outdoor installations.

Substitute Selection (HARTING 19200030627): The HARTING 19200030627 serves as a functional substitute when IP44 protection is sufficient for the application environment. This part is suitable for indoor or partially protected installations where dust and water exposure is moderate. The polycarbonate housing offers lightweight construction and chemical resistance properties distinct from zinc die cast alternatives. Both parts maintain identical mechanical interface specifications (M20 thread, side entry configuration, locking clip mechanism) and identical operating temperature performance.

Compliance Considerations: Both parts carry Active product status and are manufactured by established heavy duty connector suppliers. The HARTING 19200030627 includes RoHS3 compliance and REACH unaffected status documentation. Selection should be based on specific environmental protection requirements and material compatibility with the installation environment.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 19200030627 directly replace the LAPP 19427300 in all applications?

A: Direct replacement is mechanically feasible due to identical thread size (M20), side entry configuration, and locking mechanism. However, the reduced ingress protection rating (IP44 versus IP65) requires environmental assessment. Applications in high-moisture or high-dust environments should retain the LAPP 19427300. Applications in controlled indoor environments may accept the HARTING substitute.

Q: What is the difference between IP65 and IP44 ratings in this connector context?

A: IP65 provides complete dust protection and water jet resistance from any direction. IP44 provides splash protection and limited dust ingress. The LAPP 19427300 (IP65) is suitable for outdoor, washdown, and high-humidity environments. The HARTING 19200030627 (IP44) is suitable for indoor industrial environments with occasional moisture exposure.

Q: Are the housing materials interchangeable from a durability perspective?

A: Zinc die cast (LAPP 19427300) and polycarbonate (HARTING 19200030627) offer different performance characteristics. Zinc die cast provides superior corrosion resistance and mechanical strength in harsh environments. Polycarbonate offers chemical resistance and lighter weight. Material selection depends on specific environmental exposure (salt spray, chemical exposure, mechanical stress).

Q: Do both parts use identical locking mechanisms?

A: Yes. Both the LAPP 19427300 and HARTING 19200030627 employ a single locking clip located on the base bottom. Installation and removal procedures are identical.

Q: What is the operating temperature compatibility between these parts?

A: Both parts operate across the identical temperature range of -40°C to 125°C. No thermal performance differentiation exists between the two options.

Q: Are there packaging or inventory considerations for substitution?

A: Both parts are supplied in bulk packaging. Current inventory shows 699 units of LAPP 19427300 and 722 units of HARTING 19200030627 in stock. Procurement decisions may consider availability and lead time factors.

Q: How do the size designations HA3/4 and 3A relate to each other?

A: HA3/4 (LAPP designation) and 3A (HARTING designation) represent equivalent size classifications within their respective manufacturer series. Both accommodate identical M20 thread specifications and mechanical envelope requirements.
