Engineering Selection Recommendations

Both the SCHURTER 0034.5032 and SCHURTER 0034.3761 are active production components with full regulatory compliance. The main part carries cURus approval, while the substitute carries cULus approval. Both parts are ROHS3 compliant and REACH unaffected. The substitute part 0034.3761 is available in higher inventory quantity (1875 pcs vs. 1035 pcs), providing supply chain flexibility. Selection between these parts should be based on approval agency requirements specific to the end application and regional regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 0034.3761 be used as a direct replacement for SCHURTER 0034.5032?

A: Yes. Both parts share identical electrical ratings (80 mA, 250 V AC), fuse type (cartridge, glass), response time (slow blow), mechanical dimensions (5mm x 20mm), and breaking capacity (35 A). Both operate across the same temperature range (-40°C ~ 85°C) and meet ROHS3 compliance requirements.

Q: What is the difference between the FTT 5x20 and FSL 5x20 series designations?

A: The series designation indicates the internal product line within SCHURTER's fuse portfolio. Both series meet the same electrical and mechanical specifications for this 80 mA, 250 V application. Series differences do not affect functional compatibility.

Q: Are there differences in approval certifications between these parts?

A: The main part (0034.5032) carries cURus approval, while the substitute (0034.3761) carries cULus approval. Both certifications are recognized regulatory standards. Selection should align with the specific approval requirements of the end application and target market.

Q: What does the Melting I²t value represent, and why does it differ between parts?

A: Melting I²t is a thermal characteristic indicating the fuse element's response to overcurrent conditions. The main part specifies 0.032 while the substitute specifies 0.0367. Both values fall within the slow-blow fuse classification for this current rating and do not affect substitution eligibility for applications designed to this specification.

Q: Are both parts suitable for AC and DC applications?

A: Yes. Both parts are rated for 250 V AC/DC operation, confirming suitability for both alternating and direct current applications within the specified voltage and current parameters.
