LAPP 104740 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The LAPP 104740 is a box mount connector base designed for side entry applications with PG21 thread size and HA32 form factor. This component provides IP65 ingress protection suitable for dust-tight and water-resistant installations in industrial environments. The part operates across a temperature range of -40°C to 125°C and features aluminum alloy housing with powder-coated finish.

The 104740 carries a Last Time Buy product status, indicating discontinued production. Identification of functionally equivalent substitute parts is necessary to ensure continued availability and system compatibility for new installations and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LAPP 104740 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Connector Type: Base - Box Mount
• Style: Side Entry
• Size: HA32
• Thread Size: PG21
• Ingress Protection: IP65 minimum
• Housing Material: Aluminum Alloy
• Physical Dimensions: 106.00mm x 57.00mm x 75.00mm
• Lock Mechanism: Locking Clip (2) on Base Bottom

The LAPP 10474000 qualifies as a manufacturer-recommended substitute. This part maintains identical mechanical and electrical specifications across all critical parameters. Both components belong to the EPIC® series family and share the same form factor, mounting configuration, and environmental protection rating.

Parameter Comparison

Engineering Selection Recommendations

The LAPP 10474000 is the manufacturer-recommended substitute for the discontinued LAPP 104740. Both components maintain functional equivalence across all mechanical and environmental specifications critical to box mount connector base applications.

Selection Basis:

The 10474000 carries Active product status, ensuring continued availability and supply chain reliability compared to the Last Time Buy status of the 104740. This transition aligns with standard component lifecycle management practices.

The operating temperature range difference (-40°C to 100°C for the 10474000 versus -40°C to 125°C for the 104740) represents a constraint that must be evaluated against specific application requirements. Applications operating above 100°C require retention of the original 104740 specification or engineering review of thermal requirements.

All other parameters—connector type, form factor, thread size, ingress protection rating, housing material, and physical dimensions—remain identical, ensuring direct mechanical and electrical compatibility in standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the LAPP 10474000 directly replace the LAPP 104740 in existing installations?

A: The 10474000 provides direct mechanical and electrical compatibility for applications operating within the -40°C to 100°C temperature range. Applications requiring operation above 100°C require engineering evaluation of thermal performance or retention of the original 104740 part number.

Q: What determines whether a part qualifies as a substitute for the 104740?

A: Substitution requires equivalence across connector type (Base - Box Mount), style (Side Entry), size (HA32), thread size (PG21), ingress protection (IP65), housing material (Aluminum Alloy), physical dimensions (106.00mm x 57.00mm x 75.00mm), and lock mechanism (Locking Clip on Base Bottom).

Q: Why is the 104740 listed as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. The 10474000 represents the active production equivalent, ensuring long-term supply availability.

Q: Are there packaging differences between the 104740 and 10474000?

A: The 104740 is supplied in Bulk packaging. Packaging information for the 10474000 is not specified in the available data. Packaging requirements should be confirmed with the supplier for procurement planning.

Q: What is the inventory status for these parts?

A: The 104740 has 669 pieces in stock (Last Time Buy status). The 10474000 has 1012 pieces in stock (Active status), providing greater availability for new orders.
