Substitute Part Grouping Explanation

Substitution for the 0213.800M is determined by three critical parameters: current rating (800 mA), voltage rating (250 V AC), and physical form factor (5mm x 20mm). All substitute parts maintain these core electrical and mechanical specifications. The substitute parts are grouped into two categories based on melting I²t characteristics and approval agencies:

Category 1 (Series 213 & 219XA): Parts with melting I²t values of 9.35–9.42 and breaking capacity of 35A–150A. These include 0213.800MXBP, 0213.800MXP, 0213.800TXP, 0219.800MXABP, and 0219.800MXAP.

Category 2 (Series 218): Parts with melting I²t value of 3.37 and breaking capacity of 35A. These include 0218.800HXP, 0218.800MXBP, 0218.800MXP, 0218.800TXP, and 0218.800VXP.

All substitute parts are RoHS3 compliant and carry active product status.

Engineering Selection Recommendations

All substitute parts maintain the core electrical specifications of 800 mA at 250 V AC with 5mm x 20mm form factor and slow-blow response. Selection between substitute options is based on product status and regulatory compliance:

Series 213 substitutes (0213.800MXBP, 0213.800MXP, 0213.800TXP) are direct functional equivalents with identical melting I²t (9.42) and DC cold resistance (0.1635 Ω) to the original 0213.800M. All carry active product status and RoHS3 compliance. The 0213.800MXP offers the highest inventory availability at 1762 pieces.

Series 218 substitutes (0218.800HXP, 0218.800MXBP, 0218.800MXP, 0218.800TXP, 0218.800VXP) feature a lower melting I²t value (3.37) and reduced DC cold resistance (0.0813 Ω) compared to the original part. These are suitable for applications where faster thermal response is required. The 0218.800MXP provides the largest inventory at 6600 pieces.

Series 219XA substitutes (0219.800MXABP, 0219.800MXAP) offer increased breaking capacity (150A versus 35A) while maintaining the original melting I²t (9.35) and DC cold resistance (0.1635 Ω). The 0219.800MXAP has the highest inventory availability at 6288 pieces. These parts are suitable for applications requiring higher fault current handling.

All substitute parts are RoHS3 compliant and carry active product status, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can Series 218 parts be used as direct replacements for the 0213.800M?

A: Series 218 parts maintain the same current rating (800 mA), voltage rating (250 V), and physical form factor (5mm x 20mm). However, they have a lower melting I²t value (3.37 versus 9.42) and reduced DC cold resistance (0.0813 Ω versus 0.1635 Ω). These differences result in faster thermal response. Use Series 218 substitutes only if the application circuit design accommodates the faster response characteristic.

Q: What is the difference between Series 213 and Series 219XA substitutes?

A: Both Series 213 and 219XA maintain identical melting I²t (9.42 and 9.35 respectively) and DC cold resistance (0.1635 Ω) to the original 0213.800M. The primary difference is breaking capacity: Series 213 parts are rated at 35A, while Series 219XA parts are rated at 150A. Select Series 219XA for applications with higher fault current requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed carry RoHS3 compliance status. The original 0213.800M is RoHS non-compliant. Substitution with any listed part ensures regulatory compliance.

Q: Does packaging type affect electrical performance?

A: No. Packaging designation (Bulk, indicated by suffix variations) does not affect electrical performance or mechanical compatibility. All parts require a fuse holder for installation.

Q: What is the operating temperature range for substitute parts?

A: All substitute parts operate across the same temperature range as the original part: -55°C to 125°C.
