Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0213.630MXE are qualified based on 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)
• Mounting Type: Through Hole (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 5mm x 20mm form factor (mechanical compatibility)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)

All substitute parts listed maintain these core electrical and mechanical parameters. Variations in secondary characteristics such as melting I²t, DC cold resistance, and breaking capacity are noted but do not preclude substitution when the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: Littelfuse 0213.630MXEP

The 0213.630MXEP is the direct successor to the obsolete 0213.630MXE. It maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. This part is the preferred choice for direct replacement in new designs and production continuity.

Secondary Recommendations: Littelfuse 0218.630MXEP and 0219.630MXAEP

Both parts are active Littelfuse products with ROHS3 compliance. The 0218.630MXEP offers equivalent performance with minor melting I²t variation (4.675 vs 4.8). The 0219.630MXAEP provides enhanced breaking capacity (150A vs 35A) while maintaining all other electrical parameters, suitable for applications requiring higher fault current handling.

Alternative Manufacturers: Bel Fuse Inc. and Eaton Electronics Division

The 5STP 630-R (Bel Fuse Inc.) and BK/S506-V-630-R (Eaton Electronics Division) are qualified alternatives from established manufacturers. Both maintain the required 630mA, 250VAC, slow-blow characteristics and 5mm x 20mm form factor. Selection among these alternatives should be based on supply chain availability, lead time, and established vendor relationships. The BK/S506-V-630-R offers the lowest DC cold resistance (0.186 Ohms), while the 5STP 630-R provides the lowest melting I²t (0.9).

All substitute parts carry appropriate regulatory certifications (CCC, CE, CSA, UL/cULus, VDE) and maintain the -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 0213.630MXEP be used as a direct replacement for the obsolete 0213.630MXE?

A: Yes. The 0213.630MXEP is electrically and mechanically identical to the 0213.630MXE, with the primary difference being active product status and ROHS3 compliance. No circuit modifications are required.

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

A: Both parts share identical current rating (630mA), voltage rating (250VAC), and response time (slow-blow). The 0219.630MXAEP provides higher breaking capacity (150A vs 35A) and is designated for applications requiring enhanced fault current protection. The melting I²t values are comparable (4.675 vs 4.82).

Q: Are the Bel Fuse and Eaton alternatives mechanically compatible with the original design?

A: Yes. All substitute parts maintain the 5mm x 20mm axial form factor and through-hole mounting configuration. Physical dimensions are within acceptable tolerance for standard fuse holders. Verify holder specifications if dimensional precision is critical to your application.

Q: What is the significance of melting I²t variation among substitute parts?

A: Melting I²t indicates the thermal energy required to melt the fuse element. Variations (ranging from 0.9 to 4.82 in this product group) reflect different fuse element designs. All listed parts maintain the 630mA current rating and slow-blow response characteristic. Selection should prioritize the primary electrical parameters (current, voltage, response time) over secondary thermal characteristics unless your application has specific I²t requirements.

Q: Are all substitute parts ROHS3 compliant?

A: The 0213.630MXE is RoHS non-compliant. All substitute parts listed (0213.630MXEP, 0218.630MXEP, 0219.630MXAEP, 5STP 630-R, BK/GMD-V-630-R, and BK/S506-V-630-R) are ROHS3 compliant, meeting current environmental regulations.

Q: Which substitute part offers the lowest DC cold resistance?

A: The BK/S506-V-630-R (Eaton) offers the lowest DC cold resistance at 0.186 Ohms. This characteristic may be relevant for applications sensitive to voltage drop across the fuse element during normal operation.
