Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2070.0020.11 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Current Rating: 2.5 A (direct match required for primary substitute)
• Voltage Rating: 250 V AC and 250 V DC (must match or exceed)
• Mounting Type: Surface Mount (must match)
• Package / Case: 2-SMD, J-Lead (must match)
• Response Time: Fast Blow (must match)
• Breaking Capacity: 100 A (must match)
• Physical Dimensions: 11.00mm x 4.60mm x 3.90mm (must match)
• Approval Agencies: cURus, VDE (must maintain compliance)

The SCHURTER 3403.0020.11 serves as a direct equivalent with identical electrical specifications and physical form factor. The SCHURTER 3403.0018.24 is listed as an upgrade option with a reduced current rating of 1.6 A, suitable only for applications where lower current protection is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3403.0020.11 is the primary substitute for the obsolete 2070.0020.11. Both parts maintain identical electrical specifications, physical dimensions, and regulatory approvals. The 3403.0020.11 is currently in active production status with equivalent inventory availability. The operating temperature range of the 3403.0020.11 extends to -55°C, providing enhanced low-temperature performance compared to the original part.

The SCHURTER 3403.0018.24 is classified as an upgrade option due to its reduced current rating of 1.6 A versus the original 2.5 A specification. This part is suitable only for applications where the circuit design permits lower current protection thresholds. The melting I²t value of 0.84 reflects the lower current rating and differs from the original specification of 2.6.

Both substitute parts carry identical regulatory approvals (cURus, VDE) and maintain ROHS3 compliance, ensuring continued compliance with environmental and safety standards.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 3403.0020.11 be used as a direct replacement for the 2070.0020.11?

A: Yes. The 3403.0020.11 matches all critical electrical parameters (2.5 A, 250 V AC/DC), physical dimensions (11.00mm x 4.60mm x 3.90mm), package type (2-SMD, J-Lead), and regulatory approvals (cURus, VDE). The part is currently in active production.

Q: What is the difference between the 3403.0020.11 and 3403.0018.24?

A: The primary difference is the current rating. The 3403.0020.11 maintains the original 2.5 A specification, while the 3403.0018.24 has a reduced rating of 1.6 A. The melting I²t values differ accordingly (2.6 versus 0.84). Both parts share identical voltage ratings, dimensions, and package type.

Q: Can the 3403.0018.24 be used in place of the 2070.0020.11?

A: The 3403.0018.24 can only be used if the circuit design permits operation at a 1.6 A protection threshold. The reduced current rating makes this part unsuitable for applications requiring 2.5 A protection.

Q: Are there packaging differences between the substitute parts?

A: The 3403.0020.11 is supplied in Bulk packaging, while the 3403.0018.24 is supplied in Tape & Reel (TR) format. Both maintain the same 2-SMD, J-Lead package configuration.

Q: Do the substitute parts maintain the same regulatory approvals?

A: Yes. Both substitute parts carry cURus and VDE approvals and are ROHS3 compliant, matching the regulatory status of the original 2070.0020.11.
