Substitute Part Grouping Explanation

Substitution for the SCHURTER 0034.5213 is determined by strict equivalence across the following critical parameters:

Current Rating: 200 mA (exact match required)
Voltage Rating: 250 V AC (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Response Time: Slow Blow (exact match required)
Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
Breaking Capacity: 35 A (exact match required)
Size / Dimension: 0.250" Dia x 1.250" L (exact match required)

All substitute parts listed meet these criteria. Differences in secondary parameters such as DC Cold Resistance, Melting I²t, and RoHS compliance status do not affect functional substitution but may influence selection based on system requirements and regulatory compliance.

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the SCHURTER 0034.5213 and meet the core functional requirements. Selection should be based on the following criteria:

Active Product Status: The Littelfuse 0313.200HXP, 0313.200MXP, and 0313.200VXP, along with Eaton BK/MDQ-2/10 and MDQ-2/10, are all active products with current manufacturing support, providing supply chain continuity.

Regulatory Compliance: For applications requiring ROHS3 compliance, select from Littelfuse 0313.200HXP, 0313.200MXP, or 0313.200VXP. For applications requiring CE certification in addition to CSA and UL, Littelfuse parts provide this additional approval.

Certification Coverage: Eaton MDQ series parts carry CSA and UL approvals matching the original SCHURTER part. Littelfuse 313 series parts include CE certification, providing broader international compliance.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the SCHURTER 0034.5213?

A: Yes. All listed parts meet identical electrical and mechanical specifications: 200 mA current rating, 250 V AC voltage rating, slow-blow response, 35 A breaking capacity, and 3AB/3AG package dimensions. Physical installation in existing holders is compatible.

Q: What is the difference between the Littelfuse 0313.200HXP, 0313.200MXP, and 0313.200VXP?

A: These three Littelfuse parts are parametrically equivalent across all provided specifications. Selection between them should be based on availability, lead time, and internal part numbering conventions within your supply chain.

Q: Why are some parts marked as RoHS non-compliant?

A: The Eaton BK/MDQ-2/10 is RoHS non-compliant. If your application or regulatory environment requires RoHS3 compliance, select from the Littelfuse 313 series (0313.200HXP, 0313.200MXP, 0313.200VXP) or verify compliance requirements with your system integrator.

Q: Does the DC Cold Resistance difference between parts affect substitution?

A: DC Cold Resistance values (6.59 Ohms for Littelfuse, 8.65 Ohms for Eaton) are secondary parameters. All parts meet the 35 A breaking capacity specification. Substitution is valid; however, if your circuit design depends on specific resistance characteristics, verify compatibility with your electrical design.

Q: Are there any temperature rating differences I should consider?

A: The SCHURTER 0034.5213 and all Littelfuse substitutes operate across -55°C to 125°C. Eaton MDQ series parts do not specify an operating temperature range in the provided data. For applications with extreme temperature requirements, Littelfuse parts provide documented performance across the full range.

Q: What is the Melting I²t parameter, and does it affect substitution?

A: Melting I²t is a thermal energy characteristic. The SCHURTER part specifies 0.985, while Littelfuse parts specify 0.27. Both values are within acceptable ranges for the 200 mA, 250 V slow-blow classification. Substitution is valid for standard circuit protection applications.
