SCHURTER 7030.3150 Equivalent & Substitute Parts

Part Overview

The SCHURTER 7030.3150 is an 80 mA, 220 V AC/DC slow-blow glass cartridge fuse with a 5mm x 20mm form factor. This fuse is designed for circuits requiring overcurrent protection in the 80 mA range at 220 V AC nominal voltage. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 7030.3150 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 80 mA (exact match required)
• Fuse Type: Cartridge, Glass (form factor and technology)
• Response Time: Slow Blow (protection characteristic)
• Package / Case: 5mm x 20mm (mechanical compatibility with existing holders)
• Mounting Type: Requires Holder (installation method)

Allowable Variation Parameters:

• Voltage Rating (AC): Substitute must equal or exceed 220 V
• Breaking Capacity: Substitute must equal or exceed 100 A
• Operating Temperature Range: Substitute must encompass or exceed -40°C ~ 70°C
• Product Status: Active status preferred for ongoing availability

The SCHURTER 0034.5032 satisfies substitution criteria through matching current rating, fuse type, response time, and mechanical form factor. The higher voltage rating (250 V) and extended temperature range (-40°C ~ 85°C) provide enhanced operational margin. The lower breaking capacity (35 A versus 100 A) represents a constraint that must be evaluated against circuit requirements.

Engineering Selection Recommendations

Primary Substitute: SCHURTER 0034.5032

The SCHURTER 0034.5032 is the designated substitute for the obsolete 7030.3150. Selection is based on the following engineering criteria:

• Current Rating Equivalence: Both parts are rated at 80 mA, ensuring identical overcurrent protection threshold.
• Mechanical Compatibility: Identical 5mm x 20mm form factor permits direct installation in existing fuse holders without modification.
• Functional Equivalence: Both employ slow-blow glass cartridge technology, maintaining protection response characteristics.
• Active Product Status: The 0034.5032 is in active production, ensuring long-term availability and supply chain continuity.
• Enhanced Compliance: The substitute carries cURus certification (versus UR for the main part) and ROHS3 compliance, meeting current regulatory requirements.
• Expanded Operating Range: The -40°C ~ 85°C temperature range exceeds the original -40°C ~ 70°C specification, providing operational margin in elevated ambient conditions.

Voltage Rating Consideration: The substitute's 250 V AC rating exceeds the original 220 V specification. This higher rating is compatible with 220 V circuits and provides additional safety margin. No derating is required.

Breaking Capacity Consideration: The substitute's 35 A breaking capacity is lower than the original 100 A specification. Circuit design must confirm that available fault current does not exceed 35 A at the fuse location. If fault current analysis indicates levels above 35 A, alternative substitutes with higher breaking capacity must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0034.5032 be used as a direct replacement for the 7030.3150?

A: Yes, for circuits where the available fault current does not exceed 35 A. The 0034.5032 matches all critical parameters: 80 mA current rating, slow-blow response, 5mm x 20mm form factor, and cartridge glass construction. The higher voltage rating (250 V) is compatible with 220 V applications.

Q: What is the significance of the breaking capacity difference between the two parts?

A: Breaking capacity defines the maximum fault current the fuse can safely interrupt without rupturing or creating a hazard. The 7030.3150 is rated at 100 A breaking capacity, while the 0034.5032 is rated at 35 A. If circuit analysis indicates available fault current exceeds 35 A, the 0034.5032 cannot be used. Consult circuit documentation to determine maximum available fault current at the fuse location.

Q: Are there mechanical compatibility issues between the two parts?

A: No. Both parts use identical 5mm x 20mm cartridge form factors and require the same holder type. Physical installation is identical.

Q: Does the higher voltage rating of the 0034.5032 affect circuit operation?

A: No. A fuse rated for higher voltage than the circuit voltage operates normally. The 250 V rating of the 0034.5032 is compatible with 220 V circuits and provides additional safety margin.

Q: What compliance advantages does the 0034.5032 offer?

A: The 0034.5032 carries cURus certification (combined UL and CSA approval) compared to UR certification for the 7030.3150. Additionally, the 0034.5032 is ROHS3 compliant, meeting current environmental regulations. The substitute is REACH unaffected, confirming compliance with chemical substance restrictions.

Q: Why is the 7030.3150 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The SCHURTER 0034.5032 is the active equivalent, ensuring continued availability and supply chain support.

Q: Can the 0034.5032 be used in applications requiring the full 100 A breaking capacity of the original part?

A: No. If the circuit design requires 100 A breaking capacity, the 0034.5032 is not suitable. Alternative fuse models with matching current rating and higher breaking capacity must be identified.
