Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 7100.1015.13 are classified into two categories based on parametric equivalence:

Parametric Equivalent (Full Compatibility): Parts that match all critical electrical and mechanical parameters, including current rating (1 A), voltage ratings (250 V AC/DC), response time (Slow Blow), mounting type (Through Hole), and package configuration (Radial, Box). The SCHURTER 7100.1115.13 falls into this category.

Direct Manufacturer Alternatives (Functional Substitutes): Parts from alternative manufacturers that maintain the same current rating (1 A), voltage rating (250 V AC), response time (Slow Blow), and mounting type (Through Hole), but may differ in package dimensions, breaking capacity, or melting I²t characteristics. The Littelfuse TE5® 392 series part 39211000000 qualifies as a direct substitute. The Littelfuse TR5® 372 series part 37214000001 is listed but operates at a different current rating (4 A) and is not recommended as a direct substitute for 1 A applications.

Engineering Selection Recommendations

SCHURTER 7100.1115.13 is the recommended parametric equivalent. It maintains identical electrical specifications (1 A, 250 V AC/DC, Slow Blow), identical package configuration (Radial, Box), and identical physical dimensions. Both parts are Active status products with ROHS3 compliance and cURus approval. This substitute provides direct interchangeability without design modification.

Littelfuse 39211000000 is a functional substitute for 1 A applications. It matches the current rating, AC voltage rating, response time, and mounting type. However, it differs in physical dimensions (0.335" L x 0.157" W vs. 0.453" L x 0.197" W), melting I²t (5.8 vs. 1.6), breaking capacity (25 A vs. 35 A), and operating temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C). PCB layout verification is required due to dimensional differences. This part carries broader approval certifications (CQC, cULus, KC, PSE/JET, SEMKO, VDE) compared to the original part.

Littelfuse 37214000001 is not recommended as a substitute for the SCHURTER 7100.1015.13 due to its 4 A current rating, which exceeds the original specification. This part is suitable only for applications requiring 4 A protection.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 7100.1115.13 be used as a direct replacement for SCHURTER 7100.1015.13?

A: Yes. Both parts share identical electrical parameters (1 A, 250 V AC/DC, Slow Blow), identical package configuration (Radial, Box), and identical physical dimensions (11.50mm x 5.00mm x 8.00mm). No design changes are required.

Q: What are the key differences between SCHURTER 7100.1015.13 and Littelfuse 39211000000?

A: Both parts are rated for 1 A at 250 V AC with Slow Blow response. The primary differences are physical dimensions (SCHURTER: 11.50mm x 5.00mm x 8.00mm; Littelfuse: 8.50mm x 4.00mm x 8.00mm), melting I²t (1.6 vs. 5.8), breaking capacity (35 A vs. 25 A), and operating temperature range (-40°C ~ 85°C vs. -40°C ~ 125°C). PCB footprint compatibility must be verified before substitution.

Q: Why is Littelfuse 37214000001 listed but not recommended?

A: The Littelfuse 37214000001 operates at 4 A, which is four times the current rating of the SCHURTER 7100.1015.13. It is not suitable for circuits designed for 1 A protection and would provide inadequate overcurrent protection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. SCHURTER 7100.1015.13, SCHURTER 7100.1115.13, Littelfuse 39211000000, and Littelfuse 37214000001 are all ROHS3 compliant.

Q: What approval agencies certify these fuse parts?

A: SCHURTER 7100.1015.13 and 7100.1115.13 carry cURus approval. Littelfuse 39211000000 carries CQC, cULus, KC, PSE/JET, SEMKO, and VDE approvals. Littelfuse 37214000001 carries CCC, cURus, PSE, SEMKO, and VDE approvals. Application-specific regulatory requirements should determine which certifications are necessary.
