Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0217.063MXEP is determined by strict equivalence across the following critical parameters:

• Current Rating: 63 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)

The substitute part BK/S500-V-63-R from Eaton - Electronics Division meets all critical electrical and mechanical parameters and is therefore a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 0217.063MXEP and BK/S500-V-63-R are active production parts with equivalent electrical and mechanical specifications. The 0217.063MXEP carries multiple international approvals (CCC, CE, CSA, K-MARK, SEMKO, UL, VDE) and is ROHS3 compliant. The BK/S500-V-63-R is RoHS compliant. Both parts are REACH unaffected and classified under ECCN EAR99. Selection between these parts should be based on availability, procurement lead time, and regional certification requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can BK/S500-V-63-R be used as a direct replacement for 0217.063MXEP?

A: Yes. Both parts share identical current rating (63 mA), voltage rating (250 V AC), fuse type (cartridge, glass), response time (fast blow), package dimensions (5mm x 20mm axial), and breaking capacity (35 A). They are electrically and mechanically equivalent.

Q: Are there dimensional differences between these parts?

A: The stated package case is 5mm x 20mm (Axial) for both parts. The 0217.063MXEP has a measured dimension of 0.236" Dia x 0.886" L (6.00mm x 22.50mm), while the BK/S500-V-63-R measures 0.218" Dia x 0.831" L (5.54mm x 21.10mm). These minor variations remain within the 5mm x 20mm axial package specification and do not affect through-hole mounting compatibility.

Q: What is the difference in melting I²t values?

A: The 0217.063MXEP has a melting I²t of 0.00056, while the BK/S500-V-63-R has 0.00057. This negligible difference (0.18% variance) does not affect functional equivalence for this current rating and response time classification.

Q: Which part has better compliance certifications?

A: The 0217.063MXEP carries more extensive approval agency certifications (CCC, CE, CSA, K-MARK, SEMKO, UL, VDE) compared to the BK/S500-V-63-R. Selection should align with regional and application-specific certification requirements.

Q: Are both parts suitable for the same operating temperature range?

A: The 0217.063MXEP specifies an operating temperature range of -55°C to 125°C. The BK/S500-V-63-R does not provide an operating temperature specification in the available data. Verify temperature requirements with the application before selection.
