Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 2030.0243 is determined by strict equivalence across the following critical parameters:

• Current Rating: 250mA (exact match required)
• Voltage Rating: 125VAC / 125VDC (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Fuse Type: Board Mount (exact match required)
• Package / Case: Radial, Can configuration (exact match required)
• Size / Dimension: 0.252" Dia x 0.346" (6.40mm x 8.80mm) (exact match required)
• Breaking Capacity: 100A (exact match required)
• Melting I²t: 0.0055 (exact match required)
• Operating Temperature Range: -25°C ~ 85°C (exact match required)
• Approval Agency: cURus certification (exact match required)

The SCHURTER 0034.4243 meets all substitution criteria and is classified as an active product, providing direct functional replacement capability.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain identical electrical specifications (250mA, 125VAC/125VDC, fast blow response) and mechanical dimensions (0.252" Dia x 0.346"). Both parts carry cURus approval certification and comply with ROHS3 and REACH requirements.

The primary advantage of selecting the 0034.4243 is its active product status, ensuring ongoing availability and supply chain continuity. The substitute part is available in bulk packaging with confirmed inventory of 1087 pieces.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0034.4243 be used as a direct replacement for the 2030.0243?

A: Yes. The 0034.4243 meets all electrical and mechanical specifications of the 2030.0243, including current rating (250mA), voltage rating (125VAC/125VDC), response time (fast blow), mounting type (through hole), package configuration (radial, can), physical dimensions (0.252" Dia x 8.80mm), breaking capacity (100A), and thermal characteristics (melting I²t 0.0055). Both parts carry identical cURus certification.

Q: What is the difference between the 2030.0243 and 0034.4243?

A: The primary difference is product status. The 2030.0243 is obsolete, while the 0034.4243 is active. The 0034.4243 is designated as "Board Mount (Cartridge Style Excluded)" versus the 2030.0243 designation of "Board Mount." Both parts are functionally equivalent for through-hole board mount applications with identical electrical and thermal performance.

Q: Are there any compliance or certification differences?

A: No. Both parts are cURus approved, ROHS3 compliant, and REACH unaffected. Compliance certifications are identical.

Q: What packaging options are available for the substitute part?

A: The SCHURTER 0034.4243 is available in bulk packaging with 1087 pieces in current inventory.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.252" diameter by 0.346" length (6.40mm x 8.80mm). The parts are mechanically interchangeable in through-hole board mount applications.
