Substitute Part Grouping Explanation

Substitution of the 02183.15H is determined by strict equivalence across the following parameters:

Current Rating: 3.15 A (exact match required)
Voltage Rating: 250 V AC (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Package / Case: 5mm x 20mm (exact match required)
Response Time: Slow Blow (exact match required)
Breaking Capacity: 35 A (exact match required)
Operating Temperature: -55°C to 125°C (exact match required)

All substitute parts listed below meet these criteria. Differences in melting I²t values, DC cold resistance, and approval agency certifications do not affect functional substitutability for the specified electrical and mechanical requirements. Series 213 parts are from the active product line with enhanced RoHS3 compliance. Series 218 parts maintain the original series designation with active product status and improved certifications.

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the 02183.15H based on electrical and mechanical parameters. Selection should prioritize active product status and compliance requirements:

Series 218 substitutes (02183.15HXP, 02183.15MXBP, 02183.15MXF18P, 02183.15MXF34P, 02183.15MXF5P, 02183.15MXF7P) maintain the original series designation with active product status and ROHS3 compliance. These parts carry expanded approval agency certifications including CCC, CE, CSA, K-MARK, PSE, SEMKO, UL, and VDE.

Series 213 substitutes (02133.15HXP, 02133.15MXBP, 02133.15MXP, 02133.15TXP) are from an alternative active product line with ROHS3 compliance and certifications including BSI, CCC, CE, CSA, PSE, SEMKO, UR, and VDE.

For applications requiring specific approval agency certifications, cross-reference the required certifications against the approval agency list for each substitute part. All substitutes are available in bulk packaging and maintain adequate inventory levels.

Frequently Asked Questions (FAQ)

Q: Can Series 213 parts be used interchangeably with Series 218 parts?

A: Yes. Both series meet identical electrical and mechanical specifications for 3.15 A, 250 V AC/DC, 5x20mm glass cartridge fuses with slow-blow response. Series designation does not affect functional compatibility.

Q: What is the significance of the different melting I²t values between the main part and substitutes?

A: Melting I²t is a thermal characteristic that does not affect the primary substitution criteria. All parts meet the 35 A breaking capacity requirement and operate within the -55°C to 125°C temperature range. The I²t difference reflects manufacturing process variations between series but does not impact functional equivalence for the specified current and voltage ratings.

Q: Are the packaging variants (HXP, MXBP, MXP, TXP, MXF18P, MXF34P, MXF5P, MXF7P) functionally different?

A: No. These designations indicate packaging and tape configuration variants. All variants maintain identical electrical and mechanical specifications and are functionally equivalent for circuit protection applications.

Q: Why is the original 02183.15H listed as obsolete?

A: The 02183.15H has been superseded by active product variants within the Series 218 line. The active variants provide improved compliance status (ROHS3) and expanded certification coverage while maintaining identical electrical and mechanical performance.

Q: What approval agencies are critical for my application?

A: Consult your application requirements and regional standards. All substitute parts carry multiple certifications. Series 218 parts include UL certification; Series 213 parts include CSA certification. Cross-reference your specific regulatory requirements against the approval agency list for each candidate part.

Q: Can I mix Series 213 and Series 218 parts in the same application?

A: Yes, provided your application does not specify a particular series requirement. Both series are electrically and mechanically equivalent for the 3.15 A, 250 V, 5x20mm specification.
