Key Parameters

Substitute Part Grouping Explanation

Substitution of the H090.650 is based on the following critical parameters that must remain constant:

• Current Rating: 100 mA (exact match required)
• Fuse Type: Cartridge, Glass (mechanical and functional compatibility)
• Response Time: Slow Blow (thermal response characteristic)
• Package / Case: 5mm x 20mm (physical form factor and holder compatibility)
• Mounting Type: Requires Holder (installation method)

The substitute part 0034.5033 satisfies all these core parameters while providing additional specifications including voltage ratings, thermal operating range, and regulatory compliance certifications. The substitute maintains identical current rating, fuse type, response time, and physical dimensions, ensuring direct functional equivalence within holder-based applications.

Parameter Comparison

Engineering Selection Recommendations

The 0034.5033 serves as the direct active substitute for the obsolete H090.650. Both components share identical electrical and mechanical specifications for current rating, fuse type, response time, and physical dimensions.

The 0034.5033 provides additional engineering advantages through active product status, enabling continued procurement and supply chain support. The substitute includes defined voltage ratings (250 V AC / 125 V DC), regulatory certifications (cURus approval), and RoHS3 compliance, supporting modern design standards and regulatory requirements.

Selection of the 0034.5033 is appropriate for all applications previously specified for the H090.650, provided the circuit voltage requirements do not exceed the substitute's rated specifications of 250 V AC or 125 V DC.

Frequently Asked Questions (FAQ)

Q: Can the 0034.5033 directly replace the H090.650 in existing designs?

A: Yes. Both components share identical current rating (100 mA), fuse type (cartridge glass), response time (slow blow), and physical dimensions (5mm x 20mm). The 0034.5033 is mechanically and electrically compatible with all H090.650 holder applications.

Q: What are the voltage limitations of the substitute part?

A: The 0034.5033 is rated for 250 V AC and 125 V DC. Applications operating at voltages below these ratings are fully compatible. Applications exceeding these voltage specifications require alternative component evaluation.

Q: Does the 0034.5033 fit the same holder as the H090.650?

A: Yes. Both components are 5mm x 20mm cartridge fuses requiring identical holder types. Physical form factor compatibility is confirmed.

Q: What regulatory certifications does the substitute provide?

A: The 0034.5033 carries cURus approval and is RoHS3 compliant. The H090.650 specifications do not include documented regulatory certifications.

Q: Is the 0034.5033 available for procurement?

A: Yes. The 0034.5033 is classified as active product status with documented inventory availability, ensuring supply chain continuity compared to the obsolete H090.650.

Q: Are there any thermal operating range differences?

A: The 0034.5033 specifies an operating temperature range of -40°C to 85°C. The H090.650 does not include documented thermal specifications. Applications requiring operation within this range are compatible with the substitute.
