Primary Substitution Criteria (Mandatory Match):

Current Rating: 2 A
Voltage Rating (AC): 250 V
Fuse Type: Cartridge, Glass
Response Time: Slow Blow
Package / Case: 5mm x 20mm
Mounting Type: Requires Holder
Operating Temperature Range: -55°C to 125°C

Secondary Characteristics (Allowed Variation):

Breaking Capacity @ Rated Voltage: 35A to 150A
Melting I²t: 14.45 to 92.705
DC Cold Resistance: 0.0293 to 0.0943 Ohms

Engineering Selection Recommendations

All listed substitute parts maintain the core electrical and mechanical specifications required for 2A 250VAC slow-blow fuse applications in 5x20mm holders. Selection among equivalents should be based on:

Availability and Lead Time: Series 213 parts (0213002.MXP, 0213002.TXP) offer the highest inventory levels, with 0213002.MXP at 17,911 units in stock.

Certification Coverage: The main part 0219002.MXAF5P carries CCC, CE, CSA, PSE, SEMKO, UL, and VDE approvals. Series 213 parts include BSI certification in addition to the main approvals. Series 218 parts add K-MARK and KC certifications. Series 239 parts carry CE, CSA, KC, PSE, and UL certifications. Select based on regional compliance requirements.

Breaking Capacity Considerations: The 219XA series (0219002.MXAF5P, 0219002.MXABP, 0219002.MXAP) and 239 series provide higher breaking capacities (150A and 100A respectively) compared to 213 and 218 series (35A). Applications requiring higher fault current protection should prioritize 219XA or 239 series parts.

Melting I²t and DC Cold Resistance: Series 218 parts exhibit lower melting I²t (14.45) and DC cold resistance (0.0293 Ohms), indicating faster response characteristics. Series 239 parts show higher DC cold resistance (0.0943 Ohms). Series 213 and 219XA maintain identical melting I²t (92.705) and DC cold resistance (0.0452 Ohms) to the main part.

Frequently Asked Questions (FAQ)

Q: Can I substitute 0213002.MXP for 0219002.MXAF5P?

A: Yes. Both parts share identical current rating (2A), voltage rating (250VAC), fuse type (cartridge glass), response time (slow blow), package dimensions (5x20mm), and operating temperature range (-55°C to 125°C). The 0213002.MXP has a lower breaking capacity (35A vs. 150A), which is acceptable for applications not requiring the higher fault current protection of the 219XA series.

Q: What is the difference between Series 218 and Series 219XA?

A: Series 218 and 219XA both meet the 2A 250VAC specification in 5x20mm form factor. Series 218 has a lower melting I²t (14.45 vs. 92.705) and lower DC cold resistance (0.0293 vs. 0.0452 Ohms), resulting in faster response to overcurrent conditions. Series 219XA provides higher breaking capacity (150A vs. 35A). Choose Series 218 for applications requiring faster fuse response; choose Series 219XA for higher fault current environments.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance and REACH Unaffected status, matching the environmental compliance profile of the main part 0219002.MXAF5P.

Q: Does the package dimension 5x20mm apply to all substitutes?

A: Yes. All substitute parts are specified as 5mm diameter by 20mm length cartridge fuses, ensuring mechanical compatibility with standard 5x20mm fuse holders.

Q: Which substitute part has the highest inventory availability?

A: The 0213002.MXP (Series 213) has the highest inventory at 17,911 units in stock, followed by 0218002.MXP (Series 218) at 9,616 units.

Q: Can I use a Series 239 part as a substitute?

A: Yes. Series 239 parts (0239002.HXP, 0239002.MXP, 0239002.TXP, 0239002.VXP) meet all primary substitution criteria. They provide a breaking capacity of 100A and melting I²t of 50.585, positioning them between the lower-capacity Series 213/218 and the higher-capacity Series 219XA.
