5VTP 2-R Equivalent & Substitute Parts

Part Overview

The 5VTP 2-R is a 2A 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. The slow-blow response characteristic and cartridge glass construction provide protection in circuits requiring delayed response to transient overcurrent conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5VTP 2-R is determined by strict equivalence across the following critical parameters:

• Current Rating: 2 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)

The substitute part 0213002.MXEP (Littelfuse Series 213) meets all critical electrical and mechanical parameters. Physical dimensions show minor variation within acceptable tolerances for through-hole mounting applications. Both parts maintain identical current and voltage ratings, response characteristics, and breaking capacity specifications.

Parameter Comparison

Engineering Selection Recommendations

The 0213002.MXEP from Littelfuse is a direct functional equivalent to the obsolete 5VTP 2-R. Both components share identical electrical ratings, response characteristics, and mechanical form factors. The substitute part carries active product status with established supply chain availability (15,486 units in stock versus 724 units for the original part).

Regulatory compliance is maintained across both components. The 0213002.MXEP holds broader approval agency certifications (BSI, CCC, CE, CSA, PSE, SEMKO, UR, VDE) compared to the original part (CCC, CE, CSA, cULus, SEMKO, VDE), providing enhanced market coverage. Both parts are ROHS3 compliant and REACH unaffected.

Physical dimensions show minor variation: the substitute measures 0.228" diameter x 0.886" length (5.80mm x 22.50mm) versus the original 0.217" diameter x 0.827" length (5.50mm x 21.00mm). These dimensional differences remain within acceptable tolerances for standard through-hole fuse holder applications and do not affect electrical performance or circuit protection function.

Frequently Asked Questions (FAQ)

Q: Can the 0213002.MXEP directly replace the 5VTP 2-R in existing designs?

A: Yes. Both components are 2A 250VAC slow-blow glass cartridge fuses in 5mm x 20mm through-hole form factor with identical breaking capacity (35A) and operating temperature range (-55°C to 125°C). The minor physical dimension variations are accommodated by standard fuse holder tolerances.

Q: What is the significance of the DC Cold Resistance difference (0.04 Ohms vs 0.0452 Ohms)?

A: The DC cold resistance values are within normal manufacturing tolerance ranges for this component category and do not affect circuit protection performance or fuse response characteristics in AC applications.

Q: Are there compliance differences between the two parts?

A: The 0213002.MXEP carries additional approval certifications (BSI, PSE, UR) beyond those of the 5VTP 2-R. Both parts maintain ROHS3 compliance and REACH unaffected status. The expanded certifications of the substitute part provide broader regulatory acceptance across markets.

Q: Why is the 5VTP 2-R classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Bel Fuse Inc. The 0213002.MXEP from Littelfuse provides functional continuity for applications requiring this fuse specification.

Q: What is the Melting I²t parameter and does the difference matter?

A: Melting I²t (92 vs 92.705) represents the thermal energy required to melt the fuse element. The values are equivalent for practical circuit protection purposes and fall within the same performance class for slow-blow fuses.

Q: Can the substitute part be used in new designs?

A: Yes. The 0213002.MXEP is an active product with full supply availability and meets all electrical, mechanical, and regulatory requirements for 2A 250VAC slow-blow fuse applications in 5mm x 20mm through-hole configurations.
