2JQ 1.5-R Equivalent & Substitute Parts

Part Overview

The 2JQ 1.5-R is a fast-blow glass cartridge fuse manufactured by Bel Fuse Inc., rated at 1.5 A with 350 V AC and 140 V DC voltage ratings. This component is designed for applications requiring reliable overcurrent protection in the 2AG form factor (5mm x 15mm). The part maintains active product status with full regulatory compliance across CE, CSA, cURus, and PSE certifications. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this fuse category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2JQ 1.5-R is determined by the following critical parameters:

• Current Rating: Must be 1.5 A
• Fuse Type: Must be Cartridge, Glass
• Package / Case: Must be 2AG, 5mm x 15mm form factor
• Response Time: Must be Fast Blow
• Operating Temperature Range: Must support -55°C ~ 125°C
• RoHS Compliance: Must be ROHS3 Compliant

The Littelfuse 022501.5MXP meets these core substitution criteria. While voltage ratings differ (250 V AC / 125 V DC versus 350 V AC / 140 V DC), the substitute part operates within the same mechanical envelope and current response characteristics. Voltage derating applies when substituting into circuits designed for the higher voltage ratings of the primary part.

Parameter Comparison

Engineering Selection Recommendations

Both the 2JQ 1.5-R and 022501.5MXP maintain active product status with current manufacturing support. The primary part carries cURus certification in addition to CE, CSA, and PSE approvals. The substitute part includes UL certification. Selection between these parts depends on circuit voltage requirements: the 2JQ 1.5-R is suitable for applications operating at 350 V AC or 140 V DC, while the 022501.5MXP is rated for 250 V AC or 125 V DC maximum. Both parts satisfy ROHS3 compliance requirements and operate across the full -55°C to 125°C temperature range. Mechanical compatibility is confirmed through identical 2AG package specifications.

Frequently Asked Questions (FAQ)

Q: Can the 022501.5MXP substitute for the 2JQ 1.5-R in all applications?

A: Mechanical and electrical compatibility exists for current rating and form factor. However, the substitute part has lower voltage ratings (250 V AC / 125 V DC). Substitution is valid only in circuits operating at or below these voltage levels.

Q: What is the significance of the different melting I²t values?

A: The melting I²t value (1.4 for 2JQ 1.5-R versus 0.8 for 022501.5MXP) indicates the thermal energy required to melt the fuse element. The lower value in the substitute part results in faster thermal response under fault conditions.

Q: Are both parts available in the same package?

A: Yes. Both parts use the 2AG form factor with 5mm x 15mm dimensions and require the same holder type.

Q: What certifications apply to each part?

A: The 2JQ 1.5-R carries CE, CSA, cURus, and PSE approvals. The 022501.5MXP carries CE, CSA, PSE, and UL approvals. Both meet ROHS3 compliance.

Q: What is the difference in breaking capacity between these parts?

A: The 2JQ 1.5-R has a breaking capacity of 100A AC and 150A DC at rated voltage. The 022501.5MXP has a breaking capacity of 35A AC and 10kA DC at rated voltage. Breaking capacity indicates the maximum fault current the fuse can safely interrupt.
