5VTP 1-R Equivalent & Substitute Parts

Part Overview

The 5VTP 1-R is a 1A 250VAC glass cartridge fuse manufactured by Bel Fuse Inc., designed for through-hole mounting in 5mm x 20mm form factor applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and approval certifications to ensure direct compatibility in existing circuit designs.

Substitute Part Grouping Explanation

Substitution eligibility for the 5VTP 1-R is determined by strict equivalence across the following parameters:

• Current Rating: 1 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 35A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The substitute part 0213001.MXEP (Littelfuse Inc., Series 213) meets all mandatory electrical and mechanical criteria for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The 0213001.MXEP from Littelfuse Inc. is the direct equivalent substitute for the obsolete 5VTP 1-R. Both components share identical electrical specifications (1A, 250VAC), mechanical form factor (5mm x 20mm), and functional characteristics (slow-blow response, 35A breaking capacity). The substitute part carries active product status with higher inventory availability (11,800 pcs vs. 734 pcs), ensuring long-term supply continuity.

Approval certifications for 0213001.MXEP include all certifications held by the original part (CCC, CE, CSA, SEMKO, VDE) plus additional certifications (BSI, PSE, UR), providing equivalent or enhanced regulatory compliance. Both components maintain ROHS3 compliance and identical operating temperature ranges (-55°C ~ 125°C).

Physical dimensions show minor variation (0213001.MXEP: 0.228" Dia x 0.886" L vs. 5VTP 1-R: 0.217" Dia x 0.827" L), which remains within acceptable tolerance for standard through-hole fuse holder applications. DC cold resistance values are equivalent (0.1165 Ohms vs. 0.11 Ohms).

Frequently Asked Questions (FAQ)

Q: Can 0213001.MXEP be used as a direct replacement for 5VTP 1-R without circuit modification?

A: Yes. Both components meet identical electrical ratings (1A, 250VAC), mechanical specifications (5mm x 20mm through-hole), and functional characteristics (slow-blow response). No circuit modifications are required.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The 0213001.MXEP measures 0.228" Dia x 0.886" L compared to 5VTP 1-R at 0.217" Dia x 0.827" L. These differences are within standard tolerance for through-hole fuse holder compatibility.

Q: What is the difference in melting I²t values between the parts?

A: The 5VTP 1-R specifies 28 A²s while 0213001.MXEP specifies 19.2 A²s. Both values fall within the slow-blow fuse classification for 1A rated components and maintain equivalent protection characteristics at the specified current rating.

Q: Does the substitute part meet the same regulatory certifications?

A: The 0213001.MXEP meets all certifications held by the original part (CCC, CE, CSA, SEMKO, VDE) and includes additional certifications (BSI, PSE, UR). Regulatory compliance is maintained or enhanced.

Q: Is the substitute part currently available?

A: Yes. The 0213001.MXEP is classified as active product status with 11,800 pcs in stock, compared to the obsolete 5VTP 1-R with limited remaining inventory (734 pcs).
