5TTP 10-R Equivalent & Substitute Parts

Part Overview

The 5TTP 10-R is a ceramic cartridge fuse manufactured by Bel Fuse Inc., rated for 10 A at 125 V AC/DC with a slow-blow response characteristic. This through-hole component is designed for circuit protection in applications requiring a 5mm x 20mm form factor. The part maintains active product status with full RoHS3 compliance and international approvals including CE, CSA, cULus, and PSE certification. Substitute parts are identified when equivalent current ratings, voltage compatibility, and mechanical dimensions align within acceptable tolerance ranges for the intended application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5TTP 10-R is determined by the following critical parameters:

Current Rating: 10 A (exact match required) Voltage Rating: Minimum 125 V AC (equal or higher voltage rating acceptable) Package / Case: 5mm x 20mm (Axial) (exact mechanical match required) Mounting Type: Through Hole (exact match required) Response Time: Slow Blow (exact match required) Fuse Type: Cartridge construction (ceramic or glass acceptable within voltage/current constraints)

The BK/S506-V-10-R meets these substitution criteria with matching current rating, package dimensions, mounting configuration, and response characteristic. The substitute operates at 250 V AC, which exceeds the 125 V requirement of the primary part, making it suitable for applications where the circuit voltage does not exceed the substitute's rating.

Parameter Comparison

Engineering Selection Recommendations

Both the 5TTP 10-R and BK/S506-V-10-R maintain active product status with full RoHS3 compliance. The primary part carries CE, CSA, cULus, and PSE certifications. The substitute carries BSI, CSA, cURus, IMQ, PSE/JET, SEMKO, and VDE certifications, providing broader international regulatory coverage.

Selection between these parts depends on circuit voltage requirements. The 5TTP 10-R is specified for 125 V AC applications. The BK/S506-V-10-R operates at 250 V AC and is suitable for circuits where the applied voltage does not exceed 125 V, as the higher voltage rating does not degrade performance in lower-voltage applications. The ceramic construction of the primary part differs from the glass construction of the substitute; both are acceptable cartridge fuse materials for the specified current and response characteristics.

Frequently Asked Questions (FAQ)

Q: Can the BK/S506-V-10-R replace the 5TTP 10-R in a 125 V AC circuit?

A: Yes. The substitute's 250 V AC rating exceeds the circuit requirement of 125 V AC. Both parts share identical current rating (10 A), package dimensions (5mm x 20mm), mounting type (through hole), and response time (slow blow), making them mechanically and electrically compatible for this application.

Q: What is the difference between ceramic and glass fuse construction?

A: Both ceramic and glass cartridge fuses perform the same protective function at the specified current and voltage ratings. The material difference does not affect substitution eligibility when all electrical and mechanical parameters align.

Q: Are the physical dimensions identical between these parts?

A: Dimensions are equivalent within tolerance. The 5TTP 10-R measures 0.217" Dia x 0.827" L (5.50mm x 21.00mm). The BK/S506-V-10-R measures 0.218" Dia x 0.831" L (5.54mm x 21.10mm). These variations fall within standard mechanical tolerance for through-hole cartridge fuses and do not affect interchangeability.

Q: Why does the substitute have lower DC cold resistance?

A: The BK/S506-V-10-R exhibits 0.005 Ohms compared to 0.086 Ohms for the 5TTP 10-R. This difference reflects material and construction variations between manufacturers but does not impact fuse performance in AC circuit protection applications.

Q: Which certifications should I prioritize for my application?

A: Certification selection depends on your target market and regulatory requirements. The 5TTP 10-R covers CE, CSA, cULus, and PSE. The BK/S506-V-10-R covers BSI, CSA, cURus, IMQ, PSE/JET, SEMKO, and VDE. Verify that the selected part's certifications align with your application's geographic and industry standards.
