5VTP 4-R Equivalent & Substitute Parts

Part Overview

The 5VTP 4-R is a 4A 250VAC glass cartridge fuse manufactured by Bel Fuse Inc., designed for through-hole mounting in 5mm x 20mm form factor applications. This component features slow-blow response characteristics and is rated for both AC and DC operation across a -55°C to 125°C temperature range. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and repair operations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5VTP 4-R is determined by strict alignment of the following electrical and mechanical parameters:

• Current Rating: 4 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) form factor (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 40A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

The substitute parts listed below meet all these criteria and are therefore electrically and mechanically interchangeable with the 5VTP 4-R in applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

Both 0213004.MXEP and 0218004.MXEP from Littelfuse Inc. are active product alternatives to the obsolete 5VTP 4-R. Both substitutes maintain full electrical and mechanical compatibility across all critical parameters.

The 0213004.MXEP carries broader regulatory approval coverage (BSI, CCC, CE, CSA, PSE, SEMKO, UR, VDE) and is available in higher inventory quantities (18,200 units), making it the primary substitute for general replacement applications.

The 0218004.MXEP provides an alternative with different thermal characteristics (lower Melting I²t value of 69.1 versus 226.505 in the 0213004.MXEP) and lower DC cold resistance (0.0129 Ohms versus 0.017 Ohms). This part carries UL certification in addition to other regulatory approvals and may be selected where specific thermal response characteristics are required by the application design.

Both parts are ROHS3 compliant and REACH unaffected, matching the environmental compliance profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can 0213004.MXEP and 0218004.MXEP be used interchangeably with 5VTP 4-R?

A: Both parts meet all electrical and mechanical substitution criteria for the 5VTP 4-R, including current rating, voltage rating, fuse type, package dimensions, response time, mounting type, breaking capacity, and operating temperature range. They are electrically and mechanically interchangeable.

Q: What is the difference between the two Littelfuse substitutes?

A: The primary differences are Melting I²t values (0213004.MXEP: 226.505 versus 0218004.MXEP: 69.1) and DC cold resistance (0213004.MXEP: 0.017 Ohms versus 0218004.MXEP: 0.0129 Ohms). Both maintain identical electrical ratings and mechanical form factors. Selection between them depends on application-specific thermal response requirements.

Q: Why is the 5VTP 4-R listed as obsolete?

A: The 5VTP 4-R is no longer in active production by Bel Fuse Inc. The listed substitutes from Littelfuse Inc. are active products with equivalent specifications and are recommended for new designs and ongoing maintenance applications.

Q: Are the physical dimensions identical across all three parts?

A: The 5VTP 4-R has dimensions of 0.217" Dia x 0.827" L (5.50mm x 21.00mm). Both Littelfuse substitutes have dimensions of 0.228" Dia x 0.886" L (5.80mm x 22.50mm). These minor dimensional variations remain within the 5mm x 20mm package classification and do not affect through-hole mounting compatibility.

Q: What regulatory certifications apply to the substitute parts?

A: The 0213004.MXEP carries BSI, CCC, CE, CSA, PSE, SEMKO, UR, and VDE approvals. The 0218004.MXEP carries CCC, CE, CSA, K-MARK, PSE, SEMKO, UL, and VDE approvals. Both meet the compliance requirements of the original 5VTP 4-R (CCC, CE, CSA, cULus, SEMKO, VDE).
