Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TR2-S505SC-8-R is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Current Rating: 8 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5kA (exact match required)

Mechanical Parameters:

• Fuse Type: Cartridge, Ceramic (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)

The substitute part 0215008.MRET1SPP manufactured by Littelfuse Inc. meets all critical electrical and mechanical parameters, confirming functional equivalence for direct replacement applications.

Engineering Selection Recommendations

Both the TR2-S505SC-8-R and 0215008.MRET1SPP are active production parts with equivalent electrical and mechanical specifications. Selection between these parts is based on the following factors:

Compliance & Certifications: The TR2-S505SC-8-R carries approvals from BSI, CCC/CQC, CSA, cURus, IMQ, KC, PSE/JET, SEMKO, and VDE. The 0215008.MRET1SPP carries approvals from BSI, CE, CSA, KC, METI, SEMKO, UL, and VDE. Both parts meet international safety standards applicable to ceramic cartridge fuses.

Packaging Considerations: The TR2-S505SC-8-R is supplied in Tape & Reel (TR) packaging, while the 0215008.MRET1SPP is supplied in Cut Tape (CT) packaging. Packaging selection depends on assembly process requirements and volume specifications.

Inventory Availability: TR2-S505SC-8-R: 996 units in stock 0215008.MRET1SPP: 3643 units in stock

Environmental Specifications: The 0215008.MRET1SPP specifies an operating temperature range of -55°C ~ 125°C. The TR2-S505SC-8-R does not specify an operating temperature range in the provided data.

Frequently Asked Questions (FAQ)

Q: Can the 0215008.MRET1SPP directly replace the TR2-S505SC-8-R in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical current ratings (8A), voltage ratings (250VAC), fuse types (ceramic cartridge), response times (slow blow), and physical dimensions (5mm x 20mm). Direct substitution is supported for through-hole mounting applications.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths. Selection depends on assembly equipment compatibility and order quantities.

Q: Are there differences in melting I²t values between these parts?

A: The TR2-S505SC-8-R specifies a melting I²t of 228, while the 0215008.MRET1SPP specifies 209.88. Both values fall within acceptable ranges for 8A slow-blow ceramic fuses and do not affect functional equivalence for standard circuit protection applications.

Q: Do both parts meet RoHS requirements?

A: Yes. The TR2-S505SC-8-R is RoHS Compliant. The 0215008.MRET1SPP is ROHS3 Compliant, which represents a more recent revision of the RoHS directive. Both parts satisfy RoHS compliance requirements.

Q: What certifications are critical for my application?

A: Certification requirements depend on end-use application and regional regulations. Both parts carry BSI, CSA, KC, SEMKO, and VDE approvals. The TR2-S505SC-8-R additionally carries CCC/CQC, cURus, PSE/JET approvals. The 0215008.MRET1SPP additionally carries CE, METI, and UL approvals. Verify that required certifications for your specific application are present on the selected part.
