Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 7100.1018.13 are classified based on strict electrical and mechanical parameter alignment:

Parametric Equivalent (Direct Substitution): Part 7100.1118.13 from SCHURTER Inc. maintains identical electrical specifications (2 A, 250 V AC/DC, slow blow response) and mechanical form factor (radial, box package, through-hole mounting). This part is interchangeable without circuit redesign.

Cross-Manufacturer Equivalents (Conditional Substitution): Parts 39212000000 (Littelfuse TE5® 392 series) and 37215000001 (Littelfuse TR5® 372 series) provide electrical compatibility at the 2 A and 5 A current ratings respectively, with matching 250 V AC voltage ratings and slow blow response. However, these parts exhibit differences in breaking capacity, melting I²t characteristics, physical dimensions, and thermal operating ranges that must be evaluated for specific circuit requirements.

Key Parameters Determining Substitution Eligibility:

• Current Rating (Amps)
• Voltage Rating (AC/DC)
• Response Time (Slow Blow)
• Mounting Type (Through Hole)
• Package Configuration (Radial, Box)
• Breaking Capacity @ Rated Voltage
• Melting I²t
• Operating Temperature Range

Parameter Comparison

Engineering Selection Recommendations

SCHURTER 7100.1118.13 is the primary substitute for SCHURTER 7100.1018.13. Both parts maintain identical electrical ratings, response characteristics, and physical dimensions. Both are Active product status with ROHS3 compliance and cURus approval. This substitution requires no circuit modification.

Littelfuse 39212000000 provides electrical compatibility at 2 A, 250 V AC with slow blow response and through-hole radial mounting. However, this part exhibits a reduced breaking capacity (25 A versus 35 A), increased melting I²t (21 versus 7), smaller physical dimensions (8.50mm x 4.00mm x 8.00mm versus 11.50mm x 5.00mm x 8.00mm), and extended operating temperature range (-40°C ~ 125°C). PCB layout modifications may be required due to dimensional differences. This part carries broader regulatory approvals (CQC, cULus, KC, PSE/JET, SEMKO, VDE) and higher inventory availability.

Littelfuse 37215000001 is suitable only for applications requiring 5 A current protection. This part is not electrically equivalent to the 2 A main part and introduces significantly higher melting I²t (115 versus 7), increased breaking capacity (50 A), and different physical form factor (cylindrical can, vertical orientation). This substitution is applicable only when circuit design permits higher current ratings.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 7100.1118.13 be used as a direct replacement for SCHURTER 7100.1018.13?

A: Yes. Both parts are identical in electrical specifications (2 A, 250 V AC/DC, slow blow), mechanical form factor (radial, box, through-hole), and physical dimensions (11.50mm x 5.00mm x 8.00mm). No circuit redesign is required.

Q: What are the key differences between SCHURTER 7100.1018.13 and Littelfuse 39212000000?

A: Both parts share 2 A current rating, 250 V AC voltage rating, and slow blow response. Differences include: breaking capacity (35 A versus 25 A), melting I²t (7 versus 21), physical dimensions (11.50mm x 5.00mm x 8.00mm versus 8.50mm x 4.00mm x 8.00mm), and operating temperature range (-40°C ~ 85°C versus -40°C ~ 125°C). The Littelfuse part requires PCB layout verification due to smaller footprint.

Q: Is Littelfuse 37215000001 compatible with SCHURTER 7100.1018.13?

A: No. The Littelfuse 37215000001 is rated for 5 A current protection, not 2 A. This part is not electrically equivalent and should only be used in applications where 5 A protection is required.

Q: What regulatory certifications apply to all substitute parts?

A: All listed parts are ROHS3 compliant and REACH unaffected. SCHURTER parts carry cURus approval. Littelfuse 39212000000 carries CQC, cULus, KC, PSE/JET, SEMKO, and VDE approvals. Littelfuse 37215000001 carries CCC, cURus, PSE, SEMKO, and VDE approvals.

Q: Are there packaging differences between substitute parts?

A: SCHURTER 7100.1018.13 and 7100.1118.13 are supplied in Bulk packaging. Littelfuse 39212000000 and 37215000001 are supplied in Cut Tape (CT) packaging. Reel configuration and tape specifications may differ; verify with procurement for assembly line compatibility.

Q: What is the significance of melting I²t values in fuse selection?

A: Melting I²t indicates the thermal energy required to melt the fuse element. SCHURTER 7100.1018.13 has melting I²t of 7, while Littelfuse 39212000000 has 21. Higher I²t values result in slower response to overcurrent conditions. Circuit protection characteristics may differ; thermal stress analysis is required before substitution.
