Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LAPP 704740C0 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type classification (Base - Panel Mount)
• Entry style (Bottom Entry)
• Ingress protection rating (IP65 minimum)
• Housing material compatibility (Aluminum-based construction)
• Physical dimensions within tolerance
• Locking mechanism type (Locking Clip on Base Bottom)

Substitution Logic:

The LAPP 70474000 qualifies as a manufacturer-recommended substitute. Both parts share identical connector type, entry style, size designation (HA16), ingress protection rating, housing material, finish, and locking mechanism. Dimensional specifications are identical. The primary distinction is product status: 70474000 is Active production while 704740C0 is Last Time Buy. Operating temperature range differs by 25°C maximum (70474000: -40°C to 100°C versus 704740C0: -40°C to 125°C).

The HARTING 09200160321ML qualifies as a similar substitute based on equivalent functional parameters. Both parts are panel mount base connectors with bottom entry configuration, IP65 rating, aluminum housing with powder coating, and identical physical dimensions. Size designation differs (16A versus HA16) but represents equivalent connector sizing within respective manufacturer series. Operating temperature range of 09200160321ML (-40°C to 125°C) matches the original part specification.

Parameter Comparison

Engineering Selection Recommendations

LAPP 70474000 Selection Criteria:

The LAPP 70474000 is the manufacturer-recommended substitute for the discontinued LAPP 704740C0. Both parts belong to the same EPIC® H-A series and share identical mechanical and electrical specifications with one exception: maximum operating temperature. The 70474000 operates to 100°C maximum versus 125°C for the original part. Selection of 70474000 is appropriate for applications where the maximum ambient or operating temperature does not exceed 100°C. This part maintains Active production status, ensuring long-term availability and supply chain continuity.

HARTING 09200160321ML Selection Criteria:

The HARTING 09200160321ML provides cross-manufacturer substitution capability. This part maintains all critical functional parameters including IP65 ingress protection, bottom entry configuration, aluminum housing construction, and identical locking mechanism. Operating temperature range (-40°C to 125°C) matches the original specification. Physical dimensions are equivalent with a 1.00mm height difference (26.00mm versus 25.00mm), which falls within standard mechanical tolerance ranges for panel mount applications. The 09200160321ML includes RoHS3 compliance and REACH unaffected status. Selection is appropriate for applications requiring cross-manufacturer compatibility or when LAPP series parts are unavailable.

Frequently Asked Questions (FAQ)

Q: Can LAPP 70474000 be used as a direct replacement for LAPP 704740C0?

A: Yes, with temperature consideration. The 70474000 is the manufacturer-recommended substitute and shares identical mechanical specifications and series designation. The operating temperature maximum is 100°C versus 125°C on the original part. Substitution is valid for applications operating within the 100°C limit.

Q: What is the difference between HA16 and 16A size designations?

A: HA16 is the LAPP EPIC® H-A series size designation, while 16A is the HARTING Han® A series equivalent. Both represent the same physical connector size class and are functionally equivalent for panel mount base applications.

Q: Are there dimensional compatibility concerns with the HARTING 09200160321ML?

A: The HARTING part has a height of 26.00mm compared to 25.00mm for the LAPP parts. This 1.00mm difference is within standard mechanical tolerance for panel mount connectors and does not affect functional compatibility or mounting interface.

Q: Does the HARTING 09200160321ML include additional features?

A: Yes. The HARTING part includes a cover feature and carries RoHS3 compliance certification. These additions do not affect substitution compatibility and may provide enhanced environmental protection in certain applications.

Q: What inventory status should influence part selection?

A: Current inventory levels are: LAPP 704740C0 (765 Pcs), LAPP 70474000 (836 Pcs), and HARTING 09200160321ML (693 Pcs). All three parts maintain adequate stock levels for procurement.

Q: Are there compliance or certification differences between the substitutes?

A: The HARTING 09200160321ML carries RoHS3 compliance and REACH unaffected status. The LAPP parts do not list these certifications in the provided specifications. Applications requiring RoHS3 compliance should specify the HARTING part.
