LAPP 79090400 Hood Connector Top Entry M32 HB16 Equivalent & Substitute Parts

Part Overview

The LAPP 79090400 is an EPIC® HB series heavy duty connector hood designed for top entry applications with M32 thread size. This accessory component provides dust-tight and water-resistant sealing (IP65) for industrial connector assemblies operating across -40°C to 125°C temperature ranges. The part is currently active in production with 760 units in stock.

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 when alternative sourcing is required for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LAPP 79090400 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Thread size M32 (mechanical interface requirement)
• IP65 ingress protection rating (environmental sealing specification)
• Aluminum alloy housing with powder coat finish (material and corrosion resistance)
• Operating temperature range -40°C to 125°C (thermal compatibility)
• Locking clip mechanism (functional retention method)

The HARTING 19300160737 qualifies as a substitute based on matching these core parameters. However, the following differences exist and must be evaluated for specific application requirements:

• Entry Style: LAPP part uses top entry; HARTING part uses bottom entry
• Connector Size Designation: LAPP HB16 versus HARTING 16B (different series nomenclature)
• Connector Configuration: LAPP is hood only; HARTING is hood-coupling configuration
• Lock Location: LAPP has locking clips on base bottom; HARTING has locking clips on hood top

These differences indicate the parts serve related but distinct functional roles within their respective connector ecosystems.

Parameter Comparison

Engineering Selection Recommendations

LAPP 79090400 Selection:

• Primary choice when top entry configuration is required
• Specified for applications where hood-only (non-coupling) design is mandated
• Active product status with established supply chain
• ECCN EAR99 classification applies

HARTING 19300160737 Selection:

• Alternative when bottom entry configuration is acceptable
• Suitable for cable-to-cable coupling applications
• Higher inventory availability (943 units versus 760 units)
• ROHS3 compliant with REACH unaffected status
• MSL rating 1 (unlimited moisture sensitivity level)
• Active product status with established supply chain
• ECCN EAR99 classification applies

Both parts share identical operating temperature ranges, IP65 protection ratings, M32 thread compatibility, and aluminum powder-coated housing specifications. Selection between these parts depends on mechanical installation orientation (top versus bottom entry) and connector configuration requirements (hood only versus hood-coupling).

Frequently Asked Questions (FAQ)

Q: Can the HARTING 19300160737 directly replace the LAPP 79090400 in existing assemblies?

A: Direct replacement is not recommended without mechanical design review. While both parts share M32 threading, IP65 rating, and operating temperature specifications, the HARTING part features bottom entry configuration and hood-coupling design, whereas the LAPP part uses top entry and hood-only design. Installation orientation and connector mating requirements must be verified.

Q: What is the significance of the different size designations (HB16 versus 16B)?

A: HB16 and 16B are series-specific nomenclature from LAPP EPIC® HB and HARTING Han® B product lines respectively. These designations indicate different connector ecosystems. Parts are not interchangeable based on size designation alone; compatibility is determined by the shared parameters listed in this document.

Q: Are both parts suitable for the same environmental conditions?

A: Both parts meet IP65 dust-tight and water-resistant specifications and operate across -40°C to 125°C temperature ranges. Both use aluminum alloy housing with powder coat finish. Environmental suitability is equivalent for these parameters.

Q: What is the difference between locking clip locations?

A: The LAPP 79090400 has locking clips positioned on the base bottom, while the HARTING 19300160737 has locking clips on the hood top. This difference reflects different mechanical assembly approaches within their respective connector systems and affects installation methodology.

Q: Does the HARTING part's RoHS3 compliance affect substitution eligibility?

A: RoHS3 compliance is an additional certification advantage of the HARTING part but does not disqualify the LAPP part for substitution purposes. Compliance requirements depend on end-application regulatory mandates and must be verified against specific project specifications.

Q: What packaging format is used for both parts?

A: Both parts are supplied in bulk packaging format, suitable for industrial procurement and assembly operations.
