Key Parameters

Substitute Part Grouping Explanation

The Littelfuse 0215.200HXP qualifies as a direct substitute for the 0215.200H based on the following critical parameters:

• Current Rating: Both parts rated at 200 mA
• Voltage Rating: Both rated 250 V AC
• Fuse Type & Response: Both are ceramic cartridge fuses with slow-blow characteristics
• Physical Package: Both use 5mm x 20mm form factor, compatible with identical holders
• Breaking Capacity: Both rated 1.5 kA at rated voltage
• Operating Temperature: Both operate across -55°C to 125°C range
• Mounting Configuration: Both require external holder mounting

The 0215.200HXP represents the active production equivalent, with enhanced regulatory compliance and current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The 0215.200HXP is the appropriate selection for new designs and component replacement applications. This part maintains full electrical and mechanical compatibility with the obsolete 0215.200H while offering:

• Active production status with assured long-term availability
• ROHS3 compliance, meeting current environmental regulations
• Extended regulatory approvals (CE, SEMKO, VDE) in addition to UL certification
• Improved melting I²t characteristic (0.34 vs. 0.37), providing tighter thermal performance
• Bulk packaging option for production environments

For existing systems currently using the 0215.200H, direct substitution with the 0215.200HXP is electrically and mechanically valid without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the 0215.200HXP be used as a direct replacement for the 0215.200H?

A: Yes. Both parts share identical current rating (200 mA), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (slow blow), and physical dimensions (5mm x 20mm). They are mechanically and electrically interchangeable in any application using the 0215.200H.

Q: What is the difference in DC cold resistance between these parts?

A: The 0215.200H has 1.75 Ohms while the 0215.200HXP has 1.84 Ohms. This minor variance (0.09 Ohms) falls within normal manufacturing tolerance for ceramic fuses and does not affect circuit performance in standard applications.

Q: Why is the melting I²t value different?

A: The 0215.200HXP has a melting I²t of 0.34 compared to 0.37 for the 0215.200H. Both values remain within the slow-blow fuse classification and maintain the same breaking capacity (1.5 kA). This represents improved thermal consistency in the active production part.

Q: Are there packaging differences between these parts?

A: The 0215.200H is listed with standard packaging, while the 0215.200HXP is available in bulk packaging. Both use the same 5mm x 20mm cartridge form factor and are compatible with identical fuse holders.

Q: What regulatory approvals does each part carry?

A: The 0215.200H carries UL approval. The 0215.200HXP carries CE, SEMKO, UL, and VDE approvals, providing broader international regulatory acceptance. The 0215.200HXP also meets ROHS3 compliance requirements, while the 0215.200H does not.

Q: Is the 0215.200HXP suitable for new product designs?

A: Yes. The 0215.200HXP is the active production part and is the appropriate choice for new designs. It provides current regulatory compliance, extended certifications, and assured supply chain continuity.
