Littelfuse 0219005.M Glass Cartridge Fuse 5A 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0219005.M is a 5A 250VAC glass cartridge fuse with slow-blow response characteristics, designed for 5mm x 20mm holder mounting. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing circuit protection applications. The fuse provides 150A breaking capacity at rated voltage with a melting I²t of 114, suitable for general-purpose AC/DC protection in industrial and commercial equipment operating across -55°C to 125°C temperature ranges.

Substitute Part Grouping Explanation

Substitution for the 0219005.M is determined by strict equivalence across the following critical parameters: current rating (5A), voltage rating (250VAC), fuse type (cartridge glass), response time (slow blow), physical package (5mm x 20mm), and mounting requirement (holder-based). All substitute parts listed maintain these core electrical and mechanical specifications, ensuring direct functional replacement within the same circuit protection application.

The substitute parts are grouped into two series families: Series 213 and Series 218. Both series provide active product status with RoHS3 compliance, addressing the obsolescence of the original 0219005.M (Series 219, obsolete, RoHS non-compliant). Series 213 parts feature a breaking capacity of 50A with melting I²t of 314. Series 218 parts feature a breaking capacity of 50A with melting I²t of 111, more closely matching the original part's thermal characteristics.

Engineering Selection Recommendations

For applications currently using the obsolete 0219005.M, Series 218 parts (0218005.HXP, 0218005.MXBP, 0218005.MXF11P, 0218005.MXF14P, 0218005.MXP, 0218005.TXP, 0218005.VXP) provide the closest thermal match with melting I²t of 111, compared to the original 114. These parts maintain active product status and full RoHS3 compliance. Series 218 parts carry certifications including CCC, CE, CSA, K-MARK, PSE, SEMKO, UL, and VDE, supporting global regulatory requirements.

Series 213 parts (0213005.MXBP, 0213005.MXP, 0213005.TXP) are functionally equivalent across all core electrical parameters but feature a higher melting I²t of 314. These parts are suitable for applications where thermal response characteristics can accommodate the increased I²t value. Series 213 certifications include BSI, CCC, CE, CSA, PSE, SEMKO, UR, and VDE.

All substitute parts require the same 5mm x 20mm holder mounting configuration and operate across the identical -55°C to 125°C temperature range as the original part.

Frequently Asked Questions (FAQ)

Q: Can Series 213 and Series 218 parts be used interchangeably with the 0219005.M?

A: Both series maintain the same current rating (5A), voltage rating (250VAC), fuse type (cartridge glass), response time (slow blow), and physical package (5mm x 20mm). The primary difference is melting I²t: Series 218 (I²t = 111) more closely matches the original part (I²t = 114), while Series 213 (I²t = 314) has a higher thermal threshold. Selection depends on circuit protection requirements.

Q: What is the significance of the melting I²t difference between Series 218 and Series 213?

A: Melting I²t determines the thermal energy required to melt the fuse element. Series 218 with I²t of 111 provides thermal characteristics nearly identical to the original 0219005.M (I²t = 114), ensuring comparable response to overcurrent conditions. Series 213 with I²t of 314 will tolerate higher thermal energy before melting, resulting in slower response to sustained overcurrent.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance status. The original 0219005.M is RoHS non-compliant, making the transition to compliant alternatives necessary for new designs and regulatory adherence.

Q: Do substitute parts require different holder configurations?

A: No. All substitute parts maintain the 5mm x 20mm package specification and require the same holder mounting type as the original 0219005.M. Physical installation is identical.

Q: What certifications should I verify for my specific application?

A: Series 218 parts carry CCC, CE, CSA, K-MARK, PSE, SEMKO, UL, and VDE certifications. Series 213 parts carry BSI, CCC, CE, CSA, PSE, SEMKO, UR, and VDE certifications. Verify that the selected part number includes certifications required by your target market and application standards.

Q: What is the difference between the various Series 218 part number suffixes (HXP, MXBP, MXF11P, MXF14P, MXP, TXP, VXP)?

A: All Series 218 variants listed maintain identical electrical specifications (5A, 250VAC, slow blow, 5x20mm, I²t = 111). The suffix designations reflect internal Littelfuse packaging, certification, or distribution channel variations. All are functionally equivalent for circuit protection purposes.
