G090.649 Equivalent & Substitute Parts

Part Overview

The G090.649 is an 80 mA AC DC fuse cartridge manufactured by SCHURTER Inc. in a 5mm x 20mm glass form factor. This component is classified as obsolete and requires a holder for installation. Due to its obsolete product status, identification of equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the G090.649 is based on the following critical parameters that must remain constant:

• Current Rating: 80 mA (exact match required)
• Fuse Type: Cartridge, Glass (form factor compatibility)
• Package / Case: 5mm x 20mm (physical and holder compatibility)
• Response Time: Slow Blow (thermal response characteristic)
• Mounting Type: Requires Holder (installation method)

The substitute part 0034.5032 satisfies all these core parameters. This part is manufactured by the same supplier (SCHURTER Inc.) and maintains identical electrical and mechanical specifications for the critical substitution criteria. The 0034.5032 is classified as an active product, providing improved availability compared to the obsolete G090.649.

Parameter Comparison

Engineering Selection Recommendations

The 0034.5032 is the direct substitute for the G090.649. Selection of this part is based on the following engineering factors:

Product Status: The G090.649 is obsolete, whereas the 0034.5032 is an active product with confirmed inventory availability (1035 pcs in stock versus 781 pcs for the obsolete part).

Compliance and Certifications: The 0034.5032 carries cURus approval agency certification, ROHS3 compliance, and REACH unaffected status. These certifications provide regulatory assurance for new designs and replacement applications.

Electrical and Mechanical Compatibility: Both parts maintain identical current rating (80 mA), fuse type (Cartridge, Glass), response time (Slow Blow), and package dimensions (5mm x 20mm). The substitute part provides additional electrical specifications including 250 V AC voltage rating, 35A breaking capacity, and defined melting I²t characteristics.

Physical Dimensions: The substitute part exhibits a minor diameter increase (0.205" versus 0.197"), which remains within standard holder tolerances for 5mm x 20mm cartridge fuses and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 0034.5032 be used as a direct replacement for the G090.649?

A: Yes. Both parts share identical current rating (80 mA), fuse type (Cartridge, Glass), response time (Slow Blow), and package dimensions (5mm x 20mm). The 0034.5032 is compatible with any holder designed for 5mm x 20mm glass cartridge fuses.

Q: What is the difference in physical dimensions between these parts?

A: The G090.649 has a diameter of 0.197" (5.00mm), while the 0034.5032 has a diameter of 0.205" (5.20mm). Both maintain the same length of 0.787" (20.00mm). This minor diameter variation is within standard tolerance for 5mm x 20mm cartridge fuse holders.

Q: Why does the 0034.5032 have a specified voltage rating when the G090.649 does not?

A: The G090.649 specifications do not include voltage rating data in the provided documentation. The 0034.5032 is rated for 250 V AC, which represents the electrical capability of this active product. Voltage rating specification is a standard parameter for active fuse products and does not affect substitution compatibility based on current rating and form factor.

Q: Are there compliance differences between these parts?

A: The 0034.5032 includes cURus certification, ROHS3 compliance, and REACH unaffected status. The G090.649 does not have these specifications documented. For applications requiring regulatory compliance, the 0034.5032 provides documented certifications.

Q: What is the inventory status for each part?

A: The G090.649 (obsolete) has 781 pcs in stock. The 0034.5032 (active) has 1035 pcs in stock. The active product status of the 0034.5032 ensures continued availability for future orders.

Q: Do both parts require the same holder type?

A: Yes. Both the G090.649 and 0034.5032 are cartridge fuses in 5mm x 20mm form factor and require a compatible 5mm x 20mm fuse holder for installation.
