Hood Connector Top Entry M25 HB10 IP65 (19040100) - Equivalent & Substitute Parts

Part Overview

The LAPP 19040100 is an active-status heavy duty connector hood designed for top entry applications with M25 thread size in the EPIC® HB series. This component provides IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 100°C. The hood connector features aluminum alloy housing with powder coating and dual locking clips positioned on the base bottom. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the LAPP 19040100 is based on strict alignment of critical mechanical and electrical parameters. The following parameters must match or exceed the original specification:

Critical Matching Parameters:

• Connector type must be hood configuration
• Cable entry style must be top entry
• Thread size must be M25
• Size designation must accommodate HB10 contact cavity requirements
• Lock mechanism must be dual locking clips on base bottom
• Ingress protection rating must be IP65 or higher
• Housing material must be aluminum or equivalent die-cast aluminum alloy

Secondary Compatibility Parameters:

• Operating temperature range must encompass or exceed -40°C to 100°C
• Housing finish must be powder coated
• Physical dimensions must remain within acceptable mechanical envelope tolerances

The HARTING 19300101421 (Han® B series, size 10B) satisfies all critical parameters while providing enhanced thermal capability (-40°C to 125°C) and equivalent environmental sealing. Both parts share identical thread size (M25), locking mechanism configuration, ingress protection rating (IP65), and aluminum housing construction with powder coating.

Engineering Selection Recommendations

Primary Part Selection (LAPP 19040100): Select the original LAPP 19040100 when inventory availability is confirmed and the operating temperature requirement does not exceed 100°C. This part maintains active product status and meets all specified environmental and mechanical requirements.

Substitute Part Selection (HARTING 19300101421): The HARTING 19300101421 serves as a direct functional substitute when LAPP 19040100 availability is constrained. The substitute provides equivalent mechanical interface (M25 thread, dual locking clips, top entry configuration) and environmental sealing (IP65). The substitute's extended operating temperature range (-40°C to 125°C) accommodates applications requiring thermal performance beyond the original specification. The substitute's ROHS3 compliance and REACH unaffected status provide additional regulatory documentation for applications with compliance requirements. The 6.5mm height differential (58.50mm versus 52.00mm) must be verified against mechanical envelope constraints in the target application.

Compliance Considerations: Both parts carry EAR99 ECCN classification and 8538.90.8180 HTSUS code. The HARTING substitute provides explicit RoHS3 and REACH certifications, beneficial for regulated industries. Selection should account for application-specific compliance documentation requirements.

Frequently Asked Questions (FAQ)

Q: Can HARTING 19300101421 directly replace LAPP 19040100 in existing installations?

A: Mechanical and electrical compatibility is confirmed across all critical parameters: M25 thread interface, top entry cable routing, dual locking clip retention, and IP65 environmental sealing are identical. The 6.5mm height increase must be evaluated against available mounting space. Connector series differ (EPIC® HB versus Han® B), but this does not affect functional interchangeability for hood connector applications.

Q: What is the significance of the size designation difference (HB10 versus 10B)?

A: HB10 and 10B represent equivalent contact cavity configurations within their respective manufacturer series. Both designations specify the same functional contact count and electrical interface capacity. The different nomenclature reflects LAPP and HARTING series naming conventions rather than functional differences.

Q: Does the HARTING substitute's higher operating temperature range affect compatibility?

A: No. The substitute's -40°C to 125°C range encompasses the original -40°C to 100°C specification. Extended thermal capability does not compromise compatibility; it provides additional operational margin for applications experiencing higher ambient or internal temperatures.

Q: Are there packaging or inventory considerations for substitution?

A: Both parts are supplied in bulk packaging. Current inventory shows 650 pieces for LAPP 19040100 and 996 pieces for HARTING 19300101421. Substitute selection may be driven by inventory availability and lead time requirements.

Q: What compliance documentation should be verified before substitution?

A: The HARTING 19300101421 provides explicit ROHS3 compliance and REACH unaffected status. Applications requiring regulatory documentation should reference these certifications. Both parts carry identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.

Q: How do the physical dimensions affect mechanical fit?

A: Length and width are equivalent (73.00mm and 43.00mm for LAPP; 72.60mm and 43.00mm for HARTING). The height difference of 6.5mm (52.00mm versus 58.50mm) must be evaluated against available vertical clearance in the installation environment. Thread interface (M25) and locking clip positioning remain identical.
