Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0034.1529.PT are identified based on the following critical parameters that must match or remain compatible:

• Current Rating: 50 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)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The substitute parts listed below meet all these critical parameters. Variations in physical dimensions, DC cold resistance, and approval agencies are permitted within the scope of this product category, provided the core electrical characteristics and compliance status remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

Both Littelfuse substitute parts maintain full electrical equivalence to the SCHURTER 0034.1529.PT across all critical parameters. Selection between available options depends on mounting requirements:

Littelfuse 0217.050MXEP provides direct through-hole mounting compatibility identical to the original SCHURTER part. This option is suitable for applications where the fuse mounts directly into PCB through-holes without additional holder hardware.

Littelfuse 0217.050HXP requires a separate fuse holder for installation. This option is applicable only in designs where a fuse holder is already integrated into the circuit or where holder-based mounting is preferred.

All substitute parts carry Active product status and maintain ROHS3 compliance and REACH Unaffected designation, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can Littelfuse 0217.050MXEP be used as a direct replacement for SCHURTER 0034.1529.PT?

A: Yes. The Littelfuse 0217.050MXEP meets all critical electrical parameters (50 mA, 250 V AC, fast-blow response, 35 A breaking capacity) and provides through-hole mounting identical to the original part. Physical dimensions vary slightly but remain within acceptable tolerances for standard PCB through-hole applications.

Q: What is the key difference between Littelfuse 0217.050MXEP and 0217.050HXP?

A: The primary difference is mounting type. The 0217.050MXEP mounts directly through PCB holes, while the 0217.050HXP requires a separate fuse holder. Both maintain identical electrical characteristics and fast-blow response.

Q: Are there compliance or certification differences between the substitute parts and the original?

A: All parts maintain ROHS3 compliance and REACH Unaffected status. The Littelfuse parts carry additional approval agencies (CCC, CE, CSA, K-MARK, SEMKO, UL, VDE) compared to the SCHURTER part (cURus). These additional certifications do not affect substitution compatibility.

Q: Does the difference in melting I²t between parts affect substitution?

A: The melting I²t values (0.00025 for SCHURTER versus 0.00019 for Littelfuse) reflect minor manufacturing variations within the same fast-blow fuse category. Both values maintain the specified 50 mA current rating and 35 A breaking capacity, ensuring functional equivalence in circuit protection applications.

Q: Can these parts be used interchangeably in existing designs?

A: Littelfuse 0217.050MXEP can be used interchangeably in designs using through-hole mounting. Littelfuse 0217.050HXP requires holder-based mounting and is suitable only for designs incorporating fuse holder hardware.
