LAPP 100740 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The LAPP 100740 is a box mount connector base designed for side entry applications with PG21 thread size and HB16 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 100740 carries a Last Time Buy product status, indicating discontinued production. Identifying equivalent substitute parts is necessary to ensure continued availability for maintenance, repair, and new system designs requiring compatible connector bases.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LAPP 100740 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Base - Box Mount
• Style: Side Entry
• Size: HB16
• Thread Size: PG21
• Ingress Protection Rating: IP65
• Housing Material: Aluminum Alloy
• Housing Finish: Powder Coated
• Dimensions: 117.00mm L × 57.00mm W × 64.00mm H
• Lock Location: Locking Clip (2) on Base Bottom

The substitute part 10074000 maintains identical specifications across all critical mechanical and environmental parameters. The primary distinction lies in product status and operating temperature range, which affects application suitability in specific thermal environments.

Parameter Comparison

Engineering Selection Recommendations

For applications operating at or below 100°C: Part 10074000 is a direct functional substitute. This part maintains active production status with LAPP, ensuring long-term availability and supply chain continuity. The identical mechanical, dimensional, and environmental protection specifications enable direct replacement in existing installations and new designs.

For applications requiring operation above 100°C up to 125°C: The original 100740 specification must be retained. The substitute 10074000 has a reduced maximum operating temperature of 100°C, making it unsuitable for high-temperature environments where the full 125°C capability is required.

Compliance and Certification: Both parts carry identical ingress protection ratings (IP65), housing materials, and finishes. No additional compliance verification is required when substituting within the specified temperature constraints.

Frequently Asked Questions (FAQ)

Q: Can part 10074000 be used as a direct replacement for 100740 in all applications?

A: Direct replacement is valid only for applications where the maximum operating temperature does not exceed 100°C. The original 100740 supports operation up to 125°C, while 10074000 is rated to 100°C maximum. Verify your application's thermal requirements before substitution.

Q: What are the mechanical compatibility criteria for these connector bases?

A: Both parts share identical specifications for connector type (Base - Box Mount), style (Side Entry), size (HB16), thread size (PG21), dimensions (117.00mm × 57.00mm × 64.00mm), and locking mechanism (Locking Clip (2) on Base Bottom). These parameters ensure mechanical interchangeability.

Q: Why is 100740 marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued this part number. The substitute 10074000 is the active production equivalent, ensuring continued availability for future orders and maintenance requirements.

Q: Are there environmental protection differences between these parts?

A: No. Both parts maintain identical IP65 ingress protection ratings, aluminum alloy housing with powder-coated finish, and gray color. Environmental sealing and dust/water resistance specifications are equivalent.

Q: What should be considered when selecting between these parts for new designs?

A: For new designs, specify 10074000 due to its active production status and assured long-term availability. Use 100740 only if your application specifically requires the extended 125°C operating temperature and existing inventory is available.

Q: Are there packaging differences between these parts?

A: The original 100740 is supplied in Bulk packaging. Packaging information for 10074000 is not specified in the available data. Contact the supplier for current packaging options and quantities.
