Key Parameters

Substitute Part Grouping Explanation

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

Electrical Parameters:

• Current Rating: 10 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)

Mechanical Parameters:

• Fuse Type: Cartridge, Ceramic (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)

Compliance Parameters:

• RoHS Status: RoHS Compliant or ROHS3 Compliant (acceptable equivalence)

All three substitute parts meet these criteria and are classified as direct equivalents for the BK/S501-V-10-R.

Parameter Comparison

Engineering Selection Recommendations

All three Littelfuse substitute parts (0216010.MRET1P, 0216010.MXEP, and 0216010.MXESPP) are electrically and mechanically equivalent to the BK/S501-V-10-R and maintain active product status.

0216010.MXEP (Littelfuse) is the primary substitute recommendation. This part is supplied in bulk packaging, matching the original part's packaging format. It carries approval certifications including CCC, CE, CSA, K-MARK, PSE, SEMKO, and UL, providing broad regulatory coverage. Current inventory availability is 4973 pieces.

0216010.MXESPP (Littelfuse) serves as an alternative substitute with identical electrical specifications. This part is supplied in bulk packaging and carries CE, CSA, CQC, PSE, and UR certifications. Current inventory availability is 1120 pieces. Physical dimensions are 0.205" Dia x 0.787" L (5.20mm x 20.00mm), representing a tighter tolerance variant within the 5mm x 20mm specification.

0216010.MRET1P (Littelfuse) is available in cut tape packaging format. This configuration is suitable for automated assembly environments. Certifications include CE, CSA, ICC, PSE, SEMKO, TUV, and UR. Current inventory availability is 2025 pieces.

All substitute parts demonstrate ROHS3 compliance, REACH unaffected status, and DC cold resistance values within acceptable engineering tolerance of the original specification.

Frequently Asked Questions (FAQ)

Q: Can 0216010.MXEP be used as a direct replacement for BK/S501-V-10-R?

A: Yes. Both parts share identical electrical ratings (10 A, 250 V AC), fuse type (ceramic cartridge), response time (fast blow), breaking capacity (1.5 kA), and mechanical package (5mm x 20mm through-hole axial). Both are supplied in bulk packaging and maintain active product status.

Q: What is the difference between the three Littelfuse substitutes?

A: The primary difference is packaging format. 0216010.MXEP and 0216010.MXESPP are supplied in bulk packaging, while 0216010.MRET1P is supplied in cut tape format. 0216010.MXESPP features a tighter physical dimension tolerance (5.20mm x 20.00mm) compared to the other variants (5.80mm x 22.50mm). All three maintain identical electrical specifications.

Q: Are there any compliance or certification differences?

A: All three substitutes carry multiple international certifications. 0216010.MXEP includes CCC and K-MARK certifications in addition to CE, CSA, PSE, SEMKO, and UL. 0216010.MXESPP includes CQC certification. 0216010.MRET1P includes ICC and TUV certifications. Selection should be based on specific regulatory requirements for the target application region.

Q: How do the DC cold resistance values compare?

A: The original BK/S501-V-10-R specifies 0.008 Ohms. All three Littelfuse substitutes specify 0.0079 Ohms, representing a 1.25% variance within acceptable engineering tolerance for ceramic fuse cartridges.

Q: Which substitute is recommended for automated assembly?

A: 0216010.MRET1P is supplied in cut tape packaging, which is optimized for automated pick-and-place assembly equipment. The other two substitutes are supplied in bulk packaging, suitable for manual assembly or bulk handling processes.

Q: Are all substitutes RoHS compliant?

A: Yes. The original part is RoHS Compliant. All three substitutes are ROHS3 Compliant, which represents an updated compliance standard that maintains backward compatibility with RoHS requirements.

Q: What is the operating temperature range for the substitutes?

A: All three Littelfuse substitutes specify an operating temperature range of -55°C to 125°C. The original BK/S501-V-10-R does not specify an operating temperature range in the provided data.
