2JS 6-R Equivalent & Substitute Parts

Part Overview

The 2JS 6-R is a 6A slow-blow glass cartridge fuse manufactured by Bel Fuse Inc., rated for 350V AC and 140V DC operation. This component is designed for applications requiring reliable overcurrent protection in industrial and commercial equipment. The fuse operates within a temperature range of -55°C to 125°C and meets international safety standards including CE, CSA, cURus, and PSE certifications. The product maintains active status with 1054 units in current inventory.

Equivalent and substitute parts are identified when applications require alternative sourcing due to inventory constraints, supply chain considerations, or when system voltage ratings permit operation at lower voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2JS 6-R with the Littelfuse 0229006.MXP is permissible under the following conditions:

Matching Parameters (Required for Substitution):

• Current Rating: 6 A (identical)
• Fuse Type: Cartridge, Glass (identical)
• Package / Case: 2AG, 5mm x 15mm (identical)
• Response Time: Slow Blow (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• RoHS Compliance: ROHS3 Compliant (identical)

Voltage Rating Consideration: The 0229006.MXP operates at 125V AC / 125V DC, which is lower than the 2JS 6-R specification of 350V AC / 140V DC. Substitution is valid only in applications where the actual system voltage does not exceed 125V AC or 125V DC.

Mechanical Compatibility: Both fuses utilize the 2AG holder interface and share compatible physical dimensions within the specified tolerance range.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (2JS 6-R): Select the 2JS 6-R when system voltage specifications require 350V AC or 140V DC operation. This part carries active product status with established inventory availability and meets all required international certifications including CE, CSA, cURus, and PSE.

Substitute Selection (0229006.MXP): The Littelfuse 0229006.MXP serves as a functional equivalent when system voltage does not exceed 125V AC or 125V DC. This substitute maintains identical current rating, fuse type, package configuration, and response characteristics. The substitute carries UL certification in addition to CE, CSA, and PSE approvals. Both parts maintain ROHS3 compliance and identical operating temperature specifications.

Selection between these parts depends solely on system voltage requirements and certification needs specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the 0229006.MXP replace the 2JS 6-R in all applications?

A: No. The 0229006.MXP is rated for 125V AC / 125V DC maximum, while the 2JS 6-R is rated for 350V AC / 140V DC. Substitution is valid only when actual system voltage does not exceed the lower voltage rating of the substitute part.

Q: Are the physical dimensions identical between these fuses?

A: Both fuses use the 2AG package specification. The 2JS 6-R measures 0.201" diameter × 0.543" length (5.10mm × 13.80mm). The 0229006.MXP measures 0.177" diameter × 0.570" length (4.50mm × 14.48mm). Both fit standard 2AG holders, though dimensional variation exists within the specified tolerance range.

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

A: The 2JS 6-R has a breaking capacity of 100A AC and 150A DC at rated voltage. The 0229006.MXP has a breaking capacity of 400A. Breaking capacity indicates the maximum fault current the fuse can safely interrupt without rupturing the cartridge.

Q: Do both fuses have the same response time characteristics?

A: Yes. Both the 2JS 6-R and 0229006.MXP are classified as slow-blow fuses with identical melting I²t characteristics relative to their respective voltage ratings.

Q: Which certifications does each fuse carry?

A: The 2JS 6-R carries CE, CSA, cURus, and PSE certifications. The 0229006.MXP carries CE, CSA, PSE, and UL certifications. Both meet international safety standards for their respective voltage and current ratings.

Q: Are both fuses RoHS compliant?

A: Yes. Both the 2JS 6-R and 0229006.MXP are ROHS3 compliant and REACH unaffected.
