Substitute Part Grouping Explanation

Substitute parts for the 0218002.VXP are grouped based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

Current Rating: 2 A (exact match required)
Voltage Rating: 250 V AC (exact match required)
Package Dimensions: 5mm x 20mm (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Response Time: Slow Blow (exact match required)
Mounting: Requires Holder (exact match required)

Secondary Considerations:

Breaking Capacity @ Rated Voltage (varies: 35A to 150A)
Melting I²t (varies: 14.45 to 92.705)
DC Cold Resistance (varies: 0.0293 to 0.0943 Ohms)
Approval Agency certifications (varies by series)

All listed substitutes maintain identical primary electrical and mechanical specifications. Variations in breaking capacity, melting I²t, and resistance reflect different series designs (213, 218, 219XA, 239) but do not affect basic circuit protection function at rated current and voltage.

Engineering Selection Recommendations

Series 218 (0218002.VXP, 0218002.MXP, 0218002.TXP): Direct equivalents with identical electrical characteristics. All three variants carry the same approvals (CCC, CE, CSA, KC/K-MARK, PSE, SEMKO, UL, VDE) and are suitable for direct replacement. The 0218002.MXP offers highest inventory availability at 9616 units.

Series 213 (0213002.MXP, 0213002.TXP): Functionally equivalent with higher melting I²t (92.705 vs 14.45) and increased DC cold resistance (0.0452 vs 0.0293 Ohms). Approvals include BSI, CCC, CE, CSA, PSE, SEMKO, UR, VDE. The 0213002.MXP provides substantial inventory depth at 17911 units.

Series 219XA (0219002.MXABP, 0219002.MXAP): Equivalent electrical ratings with enhanced breaking capacity (150A vs 35A). Melting I²t and resistance match Series 213. Approvals: CCC, CE, CSA, PSE, SEMKO, UL, VDE. MSL rating of 1 (Unlimited) applies.

Series 239 (0239002.HXP, 0239002.MXP, 0239002.TXP, 0239002.VXP): Equivalent electrical ratings with breaking capacity of 100A and melting I²t of 50.585. DC cold resistance is higher at 0.0943 Ohms. Approvals limited to CE, CSA, KC, PSE, UL (no CCC or VDE). MSL rating of 1 (Unlimited) applies.

Selection should prioritize inventory availability and required certification profile for the target application.

Frequently Asked Questions (FAQ)

Q: Can Series 213 parts replace Series 218 parts directly? A: Yes. Both series maintain identical current rating (2A), voltage rating (250V), package dimensions (5x20mm), and response time (slow blow). Differences in melting I²t and DC resistance do not affect basic circuit protection function at rated specifications.

Q: What is the significance of breaking capacity differences (35A, 100A, 150A)? A: Breaking capacity indicates the maximum fault current the fuse can safely interrupt. Higher breaking capacity provides enhanced protection in circuits with greater fault current potential. All variants safely interrupt at their rated 2A current level.

Q: Are Series 239 parts suitable for applications requiring CCC or VDE certification? A: No. Series 239 parts carry CE, CSA, KC, PSE, and UL approvals only. Applications requiring CCC or VDE certification must use Series 218, 213, or 219XA variants.

Q: What does melting I²t represent? A: Melting I²t is the thermal energy required to melt the fuse element, expressed in ampere-squared seconds. It characterizes the fuse's thermal response. Higher values indicate slower thermal response. All variants listed are slow-blow fuses suitable for inrush current applications.

Q: Can I use a fuse with higher breaking capacity as a substitute? A: Yes. A fuse with higher breaking capacity (e.g., 219XA at 150A instead of 218 at 35A) provides equivalent or enhanced protection at the rated 2A current level and is suitable for direct substitution.

Q: Are all listed parts ROHS3 compliant? A: Yes. All substitute parts listed carry ROHS3 Compliant status and are REACH Unaffected.

Q: What is the difference between VXP, MXP, TXP, HXP, and MXABP/MXAP designations? A: These designations represent different packaging or certification variants within each series. All maintain identical electrical and mechanical specifications for the 2A 250VAC 5x20mm cartridge fuse category.
