Frequently Asked Questions (FAQ)

Q: Can Series 218 parts (02183.15MXF5P) be directly replaced with Series 213 parts (02133.15MXP)?

A: Yes, from an electrical standpoint. Both maintain 3.15 A current rating, 250 V AC voltage rating, and 5mm x 20mm package dimensions. The primary difference is Melting I²t (38.15 versus 202), which affects thermal response characteristics. Series 213 parts have slower thermal response. Certification requirements for your application determine suitability.

Q: What is the difference between the 02183.15MXP and 02183.15HXP?

A: Both are Series 218 parts with identical electrical and thermal specifications (3.15 A, 250 V, Melting I²t 38.15). The 02183.15HXP includes K-MARK certification in addition to standard approvals (CCC, CE, CSA, PSE, SEMKO, UL, VDE), while 02183.15MXP carries the same certifications without K-MARK. The 02183.15MXP has significantly higher inventory availability.

Q: When should I use Series 219XA parts (02193.15MXABP or 02193.15MXAP) instead of Series 218?

A: Series 219XA parts provide enhanced breaking capacity (150 A versus 35 A) while maintaining equivalent current and voltage ratings. Use these when your application requires higher fault current handling capability. Both maintain the same 5mm x 20mm package and slow-blow response characteristics.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the main part 02183.15MXF5P.

Q: What certifications are common across all substitute parts?

A: CCC, CE, CSA, PSE, SEMKO, and VDE certifications are present across all substitute parts. Additional certifications vary by series: Series 218 includes UL and K-MARK (selective); Series 213 includes BSI and UR; Series 219XA includes BSI and UR.
