Q090.657 Equivalent & Substitute Parts Reference

Part Overview

The Q090.657 is a 500 mA slow blow fuse cartridge manufactured by SCHURTER Inc. in a 5mm x 20mm glass construction. This component requires a compatible fuse holder for installation and operates as a protective device in AC and DC circuits. The Q090.657 carries an obsolete product status, making identification of equivalent and substitute parts essential for ongoing system maintenance and design updates. Equivalent parts must maintain the same current rating, physical dimensions, and response characteristics while accommodating available alternatives with enhanced specifications or active product status.

Substitute Part Grouping Explanation

Substitution eligibility for the Q090.657 is determined by the following critical parameters:

Primary Matching Criteria:

• Current Rating: 500 mA (exact match required)
• Package / Case: 5mm x 20mm (physical compatibility with existing holders)
• Response Time: Slow Blow (functional behavior match)
• Mounting Type: Requires Holder (installation method consistency)

Secondary Compatibility Factors:

• Fuse Type: Glass or ceramic construction acceptable (both are cartridge types)
• Voltage Rating: Substitute parts must meet or exceed the application voltage requirements
• Manufacturer: SCHURTER Inc. parts maintain design consistency

The Q090.657 is listed with two substitute parts: 7030.3280 and 0001.2501. Both maintain the 500 mA current rating and 5mm x 20mm physical dimensions. The 7030.3280 retains glass construction within the same D1TD series, while the 0001.2501 transitions to ceramic construction with enhanced voltage ratings and active product status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Series Replacement (Glass Construction): The 7030.3280 maintains the D1TD series glass cartridge design and is the closest functional equivalent to the Q090.657. Both are obsolete products from SCHURTER Inc. The 7030.3280 provides specified voltage ratings (220 V AC, 125 V DC) and holds UR approval. This part is suitable for applications requiring glass fuse construction and operating within the specified temperature range of -40°C to 70°C.

For Active Product Status with Enhanced Specifications: The 0001.2501 is the recommended substitute for new designs or long-term system support. This ceramic cartridge fuse maintains the 500 mA current rating and 5mm x 20mm form factor while offering active product status, higher voltage ratings (250 V AC, 300 V DC), extended operating temperature range (-55°C to 125°C), and dual agency approval (cURus, VDE). The ceramic construction provides improved breaking capacity (1.5 kA) compared to glass alternatives.

Dimensional Consideration: The 0001.2501 has a slightly larger diameter (5.20mm vs. 5.00mm) compared to the Q090.657 and 7030.3280. Verification of holder compatibility is necessary before selection.

Compliance and Certification: Both substitute parts carry RoHS3 compliance and REACH unaffected status. The 0001.2501 provides superior regulatory coverage with cURus and VDE certifications, making it the preferred choice for applications requiring international compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the 0001.2501 be used as a direct replacement for the Q090.657?

A: The 0001.2501 is functionally equivalent in current rating (500 mA), response time (slow blow), and mounting requirement (requires holder). However, the 0001.2501 has a diameter of 5.20mm compared to the Q090.657 at 5.00mm. Holder compatibility must be verified before installation. The ceramic construction of the 0001.2501 differs from the glass construction of the Q090.657, but both are acceptable cartridge fuse types for the 5mm x 20mm package class.

Q: What is the difference between the 7030.3280 and 0001.2501?

A: Both parts maintain 500 mA current rating and slow blow response. The 7030.3280 retains glass construction and D1TD series designation, matching the original Q090.657 design. The 0001.2501 uses ceramic construction, belongs to the SPT 5x20 series, and carries active product status. The 0001.2501 offers higher voltage ratings (250 V AC / 300 V DC vs. 220 V AC / 125 V DC), extended temperature range (-55°C to 125°C vs. -40°C to 70°C), and superior regulatory approvals (cURus, VDE vs. UR).

Q: Why is the Q090.657 marked as obsolete?

A: The Q090.657 is an obsolete product from SCHURTER Inc., indicating it is no longer in active production. For new system designs or long-term component availability, the 0001.2501 is recommended as the active product alternative.

Q: Are there voltage limitations when substituting the Q090.657?

A: The Q090.657 does not specify voltage ratings in the provided data. The 7030.3280 is rated for 220 V AC and 125 V DC, while the 0001.2501 is rated for 250 V AC and 300 V DC. Application voltage requirements must be compared against these specifications to ensure proper substitute selection.

Q: What holder compatibility issues should be considered?

A: The Q090.657 and 7030.3280 share identical dimensions (5.00mm x 20.00mm), ensuring compatibility with existing holders designed for these parts. The 0001.2501 has a slightly larger diameter (5.20mm), which may require verification against the specific holder model to ensure proper fit and electrical contact.

Q: Which substitute part is recommended for new designs?

A: The 0001.2501 is recommended for new designs due to its active product status, higher voltage ratings, extended operating temperature range, and dual agency approvals (cURus, VDE). This ensures long-term component availability and compliance with current regulatory standards.
