Substitute Part Grouping Explanation

Substitution of the 0219.630MXAE is determined by matching the following critical parameters:

Current Rating: 630 mA (exact match required)
Voltage Rating: 250 V AC (exact match required)
Response Time: Slow Blow (exact match required)
Package / Case: 5mm x 20mm (Axial) (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -55°C ~ 125°C (exact match required)

All substitute parts listed below meet these criteria. Variations in breaking capacity, melting I²t, and approval agencies are noted but do not preclude substitution when the above parameters are matched.

Engineering Selection Recommendations

Direct Replacement (Preferred): The 0219.630MXAEP is the direct equivalent of the 0219.630MXAE, maintaining identical electrical characteristics, breaking capacity, and melting I²t values. This part is in active product status and complies with ROHS3 standards, making it the recommended choice for new designs and obsolescence mitigation.

Parametric Equivalents: The 0218.630MXEP and 0213.630MXEP are parametric equivalents that match all critical electrical and mechanical parameters. Both parts are in active product status and ROHS3 compliant. These parts differ in breaking capacity (35 A versus 150 A) and melting I²t characteristics. Selection between these alternatives depends on application-specific breaking capacity requirements.

Compliance Considerations: All substitute parts carry current regulatory approvals (CCC, CE, CSA, SEMKO, UL, VDE). The 0219.630MXAEP maintains the same approval agency set as the original part. The 0218.630MXEP and 0213.630MXEP carry additional certifications (K-MARK and BSI, respectively) and are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can the 0219.630MXAEP be used as a direct replacement for the 0219.630MXAE?

A: Yes. The 0219.630MXAEP is electrically and mechanically identical to the 0219.630MXAE. Both parts share the same series designation (219XA), current rating (630 mA), voltage rating (250 V AC), response time (slow blow), package dimensions (5mm x 20mm), breaking capacity (150 A), and melting I²t (4.82). The primary difference is product status and RoHS compliance.

Q: What is the difference between the 0219.630MXAEP and the 0218.630MXEP?

A: Both parts match the critical electrical parameters (630 mA, 250 V AC, slow blow, 5mm x 20mm package). The 0219.630MXAEP has a breaking capacity of 150 A and melting I²t of 4.82, while the 0218.630MXEP has a breaking capacity of 35 A and melting I²t of 4.675. Selection depends on whether the application requires the higher breaking capacity of the 219XA series.

Q: Are all substitute parts through-hole mounted?

A: Yes. All listed substitute parts are through-hole mounted cartridge fuses with identical 5mm x 20mm (axial) package dimensions, ensuring mechanical compatibility with existing PCB designs.

Q: Do all substitute parts operate within the same temperature range?

A: Yes. All substitute parts operate across the -55°C to 125°C temperature range, matching the original part specification.

Q: What is the DC cold resistance of these fuses?

A: All parts listed, including the original 0219.630MXAE and all substitutes, have a DC cold resistance of 0.275 Ohms.
