Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0034.4216 are qualified based on the following criteria:

Electrical Equivalence: Current rating of 500 mA, voltage ratings of 125 V AC and 125 V DC, and fast-blow response time must match exactly.

Mechanical Compatibility: Through-hole mounting type and radial can package configuration must be maintained to ensure PCB footprint compatibility.

Approval Certifications: Parts must carry recognized safety approvals (cURus, CSA, UL, or QPL) to meet regulatory requirements.

Product Status: Only Active status parts are listed as substitutes, ensuring ongoing availability and manufacturer support.

The Littelfuse MICRO™ 272 series parts (0272.500H and 0272.500V) meet all substitution criteria and are cross-compatible with the original SCHURTER component.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 0272.500H and 0272.500V are direct electrical and mechanical substitutes for the SCHURTER 0034.4216. Both parts maintain identical current and voltage ratings, response characteristics, and through-hole mounting configuration. The Littelfuse alternatives provide enhanced breaking capacity (10 kA versus 100 A) and extended operating temperature range (-55°C to 125°C versus -25°C to 85°C), offering improved performance margins in demanding applications. Both substitute parts carry broader approval certifications (CSA, QPL, UL) compared to the original cURus certification, supporting compliance in multiple regulatory jurisdictions. All three parts are Active status with ROHS3 compliance, ensuring continued availability and environmental regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0272.500H or 0272.500V be used as a direct replacement for the SCHURTER 0034.4216?

A: Yes. Both Littelfuse parts are electrically and mechanically equivalent. They share identical current ratings (500 mA), voltage ratings (125 V AC/DC), response time (fast blow), and through-hole mounting configuration. PCB footprint compatibility is maintained.

Q: What is the difference between the Littelfuse 0272.500H and 0272.500V?

A: Both parts are functionally identical in electrical performance and ratings. The designation difference (H versus V) indicates orientation variants within the MICRO™ 272 series, both supporting vertical mounting on PCBs. Physical dimensions and electrical characteristics are equivalent.

Q: Are there any temperature range considerations when substituting?

A: The Littelfuse substitutes operate across -55°C to 125°C, compared to the SCHURTER original range of -25°C to 85°C. If the application operates within the original -25°C to 85°C window, both parts are fully compatible. The extended Littelfuse range provides additional margin for extreme environment applications.

Q: Do the substitute parts meet the same safety certifications?

A: The Littelfuse parts carry CSA, QPL, and UL certifications, while the original carries cURus certification. Both certification sets are recognized for fuse component approval. Verify that your application's regulatory requirements accept the Littelfuse certification profile.

Q: What is the significance of the higher breaking capacity in the Littelfuse parts?

A: The Littelfuse 0272.500H and 0272.500V provide 10 kA breaking capacity versus 100 A in the SCHURTER original. This indicates enhanced fault current handling capability, providing additional safety margin in high-fault-current circuit environments without affecting normal operation.
