Engineering Selection Recommendations

All three parts—0034.7218, 0034.6918, and 0034.7118—are active products with ROHS3 compliance and are suitable for direct substitution based on electrical and mechanical parameters.

0034.7218 (Main Part): Carries cULus approval. Belongs to the MSTU 250 series with 50A breaking capacity and 28.6 melting I²t. Current inventory: 1265 units.

0034.6918 (Substitute): Carries expanded regulatory approvals (CCC, cURus, KC, PSE/JET, VDE), indicating broader international certification. Belongs to the MXT 250 series with higher breaking capacity (100A) and lower melting I²t (16). Current inventory: 1666 units. This part is suitable for applications requiring enhanced breaking capacity or broader international compliance.

0034.7118 (Substitute): Carries cULus approval identical to the main part. Belongs to the MSTU 250 series with identical breaking capacity (50A) and melting I²t (28.6). Current inventory: 1597 units. This part provides direct functional equivalence with the main part.

Selection should be based on application-specific breaking capacity requirements and required regulatory certifications for the target market.

Frequently Asked Questions (FAQ)

Q: Can 0034.6918 be used as a direct replacement for 0034.7218?

A: Yes. Both parts share identical current rating (2 A), voltage rating (250 V AC), mounting type (through hole), package configuration (radial, can, vertical), response time (slow blow), and physical dimensions (0.335" Dia x 0.335" H). The 0034.6918 features higher breaking capacity (100A vs. 50A) and broader international certifications (CCC, cURus, KC, PSE/JET, VDE vs. cULus only), making it suitable for applications requiring enhanced protection or multi-market compliance.

Q: Can 0034.7118 be used as a direct replacement for 0034.7218?

A: Yes. The 0034.7118 is a parametric equivalent with identical electrical and mechanical specifications, including current rating, voltage rating, mounting type, package configuration, response time, dimensions, and breaking capacity (50A). Both parts belong to the MSTU 250 series and carry cULus approval.

Q: What is the difference between the MSTU 250 and MXT 250 series?

A: The MSTU 250 series (0034.7218 and 0034.7118) has a breaking capacity of 50A and melting I²t of 28.6. The MXT 250 series (0034.6918) has a breaking capacity of 100A and melting I²t of 16. Breaking capacity determines the maximum fault current the fuse can safely interrupt. Selection between series depends on the maximum prospective fault current in the application circuit.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts—0034.7218, 0034.6918, and 0034.7118—are ROHS3 compliant.

Q: What regulatory approvals does each part carry?

A: 0034.7218 and 0034.7118 carry cULus approval. 0034.6918 carries CCC, cURus, KC, PSE/JET, and VDE approvals, providing broader international market coverage.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts have identical dimensions: 0.335" Dia x 0.335" H (8.50mm x 8.50mm), ensuring mechanical compatibility in through-hole PCB applications.
