Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 7100.1014.13 are classified based on strict electrical and mechanical parameter alignment:

Parametric Equivalent (Full Compatibility): Part 7100.1114.13 (SCHURTER Inc.) matches all critical parameters including 800 mA current rating, 250 V AC/DC voltage ratings, slow blow response, through-hole radial box package, 35 A breaking capacity, and identical operating temperature range (-40°C ~ 85°C). This part is interchangeable within the same FRT 250T series.

Direct Manufacturer Alternatives (Functional Equivalents): Parts 39208000000 and 37212000001 (Littelfuse Inc.) provide functional substitution based on matching current rating, voltage rating, response time, and mounting type. However, these alternatives differ in package dimensions, breaking capacity, melting I²t characteristics, and operating temperature specifications, requiring circuit-level validation before implementation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Select SCHURTER 7100.1114.13 when component availability of the primary part (7100.1014.13) is constrained. Both parts share identical electrical specifications, mechanical dimensions, and thermal operating range, ensuring drop-in compatibility within existing circuit designs and PCB layouts.

For Cross-Manufacturer Substitution: Littelfuse 39208000000 is suitable when SCHURTER parts are unavailable and circuit design permits a 25 A breaking capacity (versus 35 A on the main part) and higher melting I²t value (3.8 versus 1.5). This part extends operating temperature to 125°C and carries broader approval certifications (CQC, cULus, KC, SEMKO, VDE). Physical package dimensions differ slightly (8.50mm L x 4.00mm W versus 11.50mm L x 5.00mm W), requiring PCB footprint verification.

Not Recommended for Direct Substitution: Littelfuse 37212000001 has a 2 A current rating, which exceeds the 800 mA specification of the main part. Although it shares 250 V AC voltage rating and slow blow response, the higher current rating and different package geometry (Radial, Can, Vertical) make this part unsuitable for direct replacement in circuits designed for 800 mA protection.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the main part specifications.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 7100.1114.13 be used as a direct replacement for 7100.1014.13?

A: Yes. Both parts are identical in current rating (800 mA), voltage ratings (250 V AC/DC), response time (slow blow), mounting type (through hole), package configuration (radial, box), breaking capacity (35 A), and operating temperature range (-40°C ~ 85°C). They are interchangeable within the FRT 250T series.

Q: What are the key differences between SCHURTER and Littelfuse 800 mA alternatives?

A: SCHURTER 7100.1014.13 and 7100.1114.13 have a melting I²t of 1.5 and breaking capacity of 35 A. Littelfuse 39208000000 has a melting I²t of 3.8 and breaking capacity of 25 A, with extended operating temperature to 125°C. Physical dimensions also differ: SCHURTER is 11.50mm L x 5.00mm W, while Littelfuse is 8.50mm L x 4.00mm W.

Q: Is Littelfuse 37212000001 compatible with circuits designed for the SCHURTER 7100.1014.13?

A: No. The 37212000001 has a 2 A current rating, which is 2.5 times higher than the 800 mA specification. This part is not suitable for direct replacement in 800 mA-rated circuits.

Q: What certifications apply to substitute parts?

A: SCHURTER 7100.1014.13 and 7100.1114.13 carry cURus certification. Littelfuse 39208000000 carries CQC, cULus, KC, SEMKO, and VDE certifications. Littelfuse 37212000001 carries CCC, cURus, PSE, SEMKO, and VDE certifications. All parts are ROHS3 compliant and REACH unaffected.

Q: Do package dimension differences affect PCB compatibility?

A: Yes. SCHURTER parts use a 11.50mm L x 5.00mm W radial box package. Littelfuse 39208000000 uses an 8.50mm L x 4.00mm W radial box package, requiring PCB footprint verification. Littelfuse 37212000001 uses a radial can vertical package (8.50mm diameter x 8.00mm height), which is mechanically incompatible with the original design.
