Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LAPP 704504 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector Type: Hood
• Style: Top Entry
• Thread Size: PG21
• Ingress Protection: IP65 minimum
• Housing Material: Aluminum Alloy
• Series: EPIC® H-A

Size Variance Allowance: The substitute part 70450400 differs in size designation (HA10 versus HB10) while maintaining identical physical dimensions (63.00mm L × 29.50mm W × 62.00mm H). This dimensional equivalence permits substitution within the same mechanical envelope.

Operating Temperature Consideration: The main part operates to 125°C while the substitute operates to 100°C. This represents a reduced upper temperature limit that must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: LAPP 70450400

The LAPP 70450400 is the manufacturer-recommended substitute for the discontinued 704504. This part maintains full mechanical and electrical compatibility across all critical parameters including connector type, thread size, ingress protection rating, and physical dimensions.

Status Advantage: The 70450400 carries Active product status, ensuring continued availability and supply chain support, whereas the 704504 is Last Time Buy with limited remaining inventory (1052 pcs).

Temperature Derating: Applications requiring sustained operation above 100°C must retain the original 704504 specification. For applications with maximum operating temperatures at or below 100°C, the 70450400 provides equivalent performance with superior long-term availability.

Secondary Cross-Reference: The substitute part list references 09200100731 as an additional equivalent. This part number should be evaluated against the same parameter criteria for applications requiring extended sourcing options.

Frequently Asked Questions (FAQ)

Q: Can the LAPP 70450400 be used as a direct replacement for 704504 in all applications?

A: The 70450400 is a direct mechanical and electrical replacement for applications operating at or below 100°C. Applications requiring the full -40°C to 125°C temperature range of the original part must retain the 704504 specification or confirm that 100°C maximum operation is acceptable.

Q: What is the significance of the size designation change from HB10 to HA10?

A: The size designation change reflects internal LAPP product line evolution within the EPIC® H-A series. The physical dimensions remain identical (63.00mm × 29.50mm × 62.00mm), and both designations are compatible with PG21 threaded applications. The designation change does not affect mechanical fit or electrical performance.

Q: Why is the 704504 classified as Last Time Buy?

A: Last Time Buy status indicates that LAPP has discontinued production of this part number. The 70450400 represents the active replacement within the product line, offering equivalent functionality with ongoing manufacturing support.

Q: Are there packaging differences between the main part and substitute?

A: The main part 704504 is supplied in Bulk packaging. The substitute 70450400 packaging specification is not provided in the available data. Packaging requirements should be confirmed with the supplier for procurement planning.

Q: What is the inventory status for each part?

A: The 704504 has 1052 pcs in stock (Last Time Buy status). The 70450400 has 988 pcs in stock (Active status). For long-term applications, the 70450400 is recommended due to its active product status and continued manufacturing availability.

Q: How do the ingress protection ratings compare?

A: Both parts provide identical IP65 ingress protection (dust tight, water resistant). No performance difference exists in environmental sealing capability between the two parts.
