2JQ 2-R Equivalent & Substitute Parts

Part Overview

The 2JQ 2-R is a 2A fast-blow glass cartridge fuse manufactured by Bel Fuse Inc., rated for 350V AC and 140V DC operation. This component is designed for circuits requiring fast-response overcurrent protection in the 2AG form factor (5mm x 15mm). The part maintains Active product status with full compliance to CE, CSA, cURus, and PSE approval agencies. 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 2-R is determined by the following critical parameters:

• Current Rating: Must be 2 A (exact match required)
• Fuse Type: Must be Cartridge, Glass (mechanical and functional compatibility)
• Package / Case: Must be 2AG, 5mm x 15mm (physical holder compatibility)
• Response Time: Must be Fast Blow (circuit protection characteristic match)
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• RoHS Compliance: Must maintain ROHS3 Compliant status

Voltage ratings (AC and DC) and breaking capacity may vary within acceptable ranges for the application circuit, provided the substitute part meets or exceeds the minimum required voltage ratings and breaking capacity specifications. The substitute part 0225002.MXP from Littelfuse Inc. meets all mechanical compatibility requirements and maintains equivalent fast-blow response characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the 2JQ 2-R and 0225002.MXP maintain Active product status and ROHS3 compliance. The 2JQ 2-R provides higher AC voltage rating (350V vs. 250V) and DC voltage rating (140V vs. 125V). The 0225002.MXP offers higher DC breaking capacity (10kA vs. 150A). Selection between these parts depends on the specific voltage and breaking capacity requirements of the target circuit. Both parts carry equivalent international approvals (CE, CSA, PSE) with the 0225002.MXP additionally certified to UL standards and the 2JQ 2-R to cURus standards. Inventory availability is comparable, with 2556 units of the 2JQ 2-R and 2347 units of the 0225002.MXP in stock.

Frequently Asked Questions (FAQ)

Q: Can the 0225002.MXP replace the 2JQ 2-R in all applications?

A: Physical and functional compatibility is confirmed for the 2AG form factor and fast-blow response. However, the 0225002.MXP has lower AC (250V vs. 350V) and DC (125V vs. 140V) voltage ratings. Substitution is valid only when the circuit operates at or below 250V AC and 125V DC.

Q: What is the significance of the 2AG package designation?

A: The 2AG designation specifies the physical form factor (5mm x 15mm cartridge) and holder compatibility. Both parts use identical 2AG packaging, ensuring mechanical interchangeability in standard fuse holders.

Q: How do breaking capacity differences affect substitution?

A: The 0225002.MXP provides 10kA DC breaking capacity compared to the 2JQ 2-R's 150A DC. Higher breaking capacity indicates the substitute can safely interrupt larger fault currents. This difference does not prevent substitution but should be evaluated against circuit fault current levels.

Q: Are there temperature operating range differences?

A: Both parts operate across the identical temperature range of -55°C to 125°C, ensuring thermal compatibility in equivalent applications.

Q: What approval agency differences exist between these parts?

A: The 2JQ 2-R carries CE, CSA, cURus, and PSE approvals. The 0225002.MXP carries CE, CSA, PSE, and UL approvals. Both share CE, CSA, and PSE certifications. The presence of UL certification on the substitute may provide additional compliance value in certain markets.
