LAPP 70450400 Hood Connector Top Entry PG21 HA10 IP65 Equivalent & Substitute Parts

Part Overview

The LAPP 70450400 is an EPIC® H-A series heavy duty connector hood designed for top entry applications with PG21 thread size and HA10 form factor. This accessory provides dust-tight and water-resistant sealing (IP65) for industrial connector assemblies operating in harsh environments. The part is currently active in production with 988 units in stock. Alternative equivalent parts may be required due to application-specific entry orientation requirements, series compatibility with existing installations, or regional component availability.

Key Parameters

Substitute Part Grouping Explanation

The HARTING 09200100731 is identified as a substitute for the LAPP 70450400 based on the following critical parameters that define functional equivalence in heavy duty connector hood applications:

Matching Parameters:

• Thread Size: PG21 (identical mounting interface)
• Ingress Protection: IP65 - Dust Tight, Water Resistant (equivalent environmental sealing)
• Housing Material: Aluminum (Die Cast) with Powder Coating (equivalent corrosion resistance and durability)
• Connector Type: Hood (same functional category)
• Size Classification: HA10 / 10A (equivalent form factor)

Differing Parameters:

• Entry Style: Top Entry (LAPP) vs. Bottom Entry (HARTING) — determines installation orientation
• Series: EPIC® H-A (LAPP) vs. Han® A (HARTING) — different manufacturer series
• Operating Temperature: -40°C to 100°C (LAPP) vs. -40°C to 125°C (HARTING) — HARTING provides extended upper range
• Lock Location: Base Bottom (LAPP) vs. Hood Top (HARTING) — different mechanical locking mechanism

Substitution is valid when application requirements permit bottom entry orientation and cross-series compatibility is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both the LAPP 70450400 and HARTING 09200100731 are active production components with equivalent IP65 environmental protection ratings and PG21 thread compatibility. Selection between these parts depends on installation geometry and series requirements:

LAPP 70450400 is the primary choice when top entry cable routing is required or when EPIC® H-A series integration with existing connector assemblies is mandatory.

HARTING 09200100731 is suitable as a substitute when bottom entry orientation accommodates the application layout and Han® A series cross-compatibility is acceptable. The extended operating temperature range (-40°C to 125°C) provides additional thermal margin in high-temperature applications. The HARTING part carries ROHS3 compliance and REACH unaffected status, confirming regulatory alignment for industrial markets.

Dimensional differences (width: 29.50mm vs. 36.00mm) must be verified against available mounting space before substitution.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09200100731 directly replace the LAPP 70450400 in existing installations?

A: Direct replacement requires verification of two factors: (1) the application must accommodate bottom entry cable entry instead of top entry, and (2) the connector series must be compatible with existing mated components. If the installation uses EPIC® H-A series contacts or housings, cross-series compatibility with Han® A must be confirmed with the system integrator.

Q: What is the significance of the PG21 thread size match?

A: PG21 is the mounting interface standard. Both parts use identical PG21 threads, ensuring mechanical fit into the same panel or enclosure cutouts. This is a critical matching parameter for physical substitution.

Q: How do the operating temperature ranges differ in practical application?

A: The LAPP part operates from -40°C to 100°C, while the HARTING part extends to 125°C. For applications operating above 100°C, the HARTING substitute provides additional thermal headroom. For standard industrial environments below 100°C, both parts are equivalent.

Q: What does IP65 rating mean for both parts?

A: IP65 indicates dust-tight and water-resistant protection. Both parts provide identical environmental sealing performance, suitable for outdoor and washdown industrial environments.

Q: Are there packaging or compliance differences?

A: The HARTING 09200100731 is supplied in bulk packaging and carries ROHS3 compliance and REACH unaffected certification. The LAPP 70450400 packaging details were not specified in the provided data. Verify packaging requirements and compliance certifications with your procurement specifications.

Q: What is the difference between "Hood" and "Hood - Coupling" connector types?

A: Both are hood-style connectors. The HARTING designation as "Hood - Coupling" indicates it is designed for cable-to-cable coupling applications. Verify that the mating connector type in your assembly is compatible with the selected hood style.
