LAPP 19109900 Equivalent & Substitute Parts Reference

Part Overview

The LAPP 19109900 is an EPIC® HB series base-mount connector designed for side entry applications with M25 thread size and HB24 configuration. This heavy-duty connector provides IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 100°C. The component is classified as Active product status with 753 units in current inventory stock.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where the primary part becomes unavailable or when inventory constraints require alternative sourcing from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LAPP 19109900 is determined by strict alignment of the following parameters:

Critical Substitution Parameters:

• Connector Type: Base - Box Mount (installation method)
• Style: Side Entry (cable entry orientation)
• Thread Size: M25 (mechanical interface standard)
• Size Configuration: HB24 or equivalent contact arrangement (24B is the HARTING equivalent designation)
• Ingress Protection: IP65 minimum (environmental sealing)

Secondary Alignment Parameters:

• Housing Material: Aluminum or Aluminum Alloy (corrosion resistance)
• Lock Location: Locking Clip on Base Bottom (retention mechanism)
• Operating Temperature: Must encompass or exceed -40°C to 100°C range

The HARTING 19300241296 (Han® B series, size 24B) meets all critical substitution parameters. The 24B designation in the Han® B series is the functional equivalent to HB24 in the EPIC® HB series, both representing 24-contact configurations with identical mechanical interfaces.

Parameter Comparison

Engineering Selection Recommendations

HARTING 19300241296 as Direct Substitute:

The HARTING 19300241296 qualifies as a functional equivalent based on matching critical parameters: identical connector type (base-mount), style (side entry), thread size (M25), ingress protection (IP65), and equivalent size configuration (24B = HB24 contact arrangement).

Both parts maintain Active product status, indicating current manufacturing support and supply chain availability. The HARTING substitute demonstrates superior thermal performance (-40°C to 125°C versus -40°C to 100°C), providing additional operational margin in high-temperature environments.

The 8mm height difference (56mm versus 64mm) must be evaluated within the specific installation envelope. Mounting surface clearance and adjacent component spacing should be verified before final selection.

Compliance Considerations:

Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications. The HARTING substitute carries RoHS3 compliance and REACH Unaffected status, providing additional regulatory alignment for applications requiring these certifications.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 19300241296 directly replace the LAPP 19109900 in existing installations?

A: Yes, provided the 8mm height difference does not conflict with the installation envelope. Both parts share identical thread size (M25), connector type (base-mount), style (side entry), and ingress protection (IP65). The mechanical interface and locking mechanism are equivalent.

Q: What is the significance of the size designation difference (HB24 versus 24B)?

A: HB24 is the LAPP EPIC® HB series designation for a 24-contact configuration. 24B is the HARTING Han® B series equivalent designation for the same 24-contact arrangement. Both represent identical contact counts and pin arrangements, making them functionally interchangeable at the electrical interface level.

Q: Does the HARTING substitute include any additional features?

A: Yes. The HARTING 19300241296 includes both Cover and Feed Through features, while the LAPP 19109900 specifies Cover only. The Feed Through capability provides additional application flexibility without compromising compatibility.

Q: Are there temperature operating range differences?

A: The HARTING substitute operates across -40°C to 125°C, exceeding the LAPP specification of -40°C to 100°C. This provides 25°C additional thermal margin, beneficial for high-temperature industrial environments.

Q: What is the inventory status for each part?

A: LAPP 19109900 has 753 units in stock. HARTING 19300241296 has 1117 units in stock, providing greater availability for immediate procurement.

Q: Are there regulatory or compliance differences between the two parts?

A: Both parts share identical ECCN and HTSUS classifications. The HARTING substitute carries RoHS3 compliance and REACH Unaffected certification, providing additional regulatory documentation for applications requiring these standards.

Q: What is the primary dimensional difference?

A: Length (144mm) and width (57mm) are identical. Height differs by 8mm: LAPP 19109900 is 64mm; HARTING 19300241296 is 56mm. This must be verified against installation space constraints.
