Substitute Part Grouping Explanation

Substitution eligibility for the 2070.0013.24 is determined by strict equivalence across the following critical parameters:

Current Rating: 500 mA (exact match required)
Voltage Rating: 250 V AC and 250 V DC (both required)
Response Time: Fast Blow
Mounting Type: Surface Mount
Package Configuration: 2-SMD, J-Lead
Physical Dimensions: 11.00 mm × 4.60 mm × 3.90 mm
Approval Certifications: cURus and VDE compliance

The SCHURTER 3403.0013.24 qualifies as a direct equivalent substitute, maintaining identical electrical and mechanical specifications while offering active product status and improved temperature operating range. The SCHURTER 3403.0012.11 is classified as a current-derating substitute due to its 400 mA current rating, which is lower than the original 500 mA specification.

Engineering Selection Recommendations

The SCHURTER 3403.0013.24 is the primary substitute for the obsolete 2070.0013.24. This part maintains complete electrical and mechanical equivalence while offering active product status, ensuring long-term availability and supply chain stability. The 3403.0013.24 provides an extended operating temperature range (-55°C to 125°C versus -40°C to 125°C) and is available in Tape & Reel packaging, supporting automated assembly processes. Both parts carry identical regulatory certifications (cURus, VDE) and maintain ROHS3 compliance.

The SCHURTER 3403.0012.11 serves as an alternative only in applications where the circuit design permits operation at 400 mA current rating. This part shares identical voltage ratings, response characteristics, and physical dimensions but operates at a reduced current threshold. Selection of the 3403.0012.11 requires circuit-level analysis to confirm that the lower current rating does not compromise system protection requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3403.0013.24 be used as a direct replacement for the 2070.0013.24?

A: Yes. The 3403.0013.24 maintains identical current rating (500 mA), voltage ratings (250 V AC/DC), response time (Fast Blow), package configuration (2-SMD, J-Lead), and physical dimensions. Both parts carry cURus and VDE certifications and are ROHS3 compliant.

Q: What is the difference between the 3403.0013.24 and 3403.0012.11?

A: The primary difference is current rating. The 3403.0013.24 is rated at 500 mA, matching the original part. The 3403.0012.11 is rated at 400 mA. Both share identical voltage ratings, response time, mounting type, and physical dimensions. The 3403.0012.11 also has a lower melting I²t value (0.02 versus 0.03).

Q: Is the 3403.0012.11 suitable for my application?

A: The 3403.0012.11 can only be used if your circuit design operates at or below 400 mA. If the original design requires 500 mA protection, the 3403.0012.11 will not provide equivalent circuit protection and is not suitable.

Q: What packaging options are available for substitute parts?

A: The 3403.0013.24 is available in Tape & Reel (TR) packaging. The 3403.0012.11 is available in Bulk packaging. Both support surface mount assembly processes.

Q: Are there any temperature range differences between the main part and substitutes?

A: Yes. The obsolete 2070.0013.24 operates from -40°C to 125°C. Both active substitutes (3403.0013.24 and 3403.0012.11) operate from -55°C to 125°C, providing an extended low-temperature operating range.

Q: Do all parts carry the same regulatory certifications?

A: Yes. The main part and both substitutes carry cURus and VDE approvals, maintain ROHS3 compliance, and are REACH Unaffected.
