Engineering Selection Recommendations
All listed substitute parts maintain electrical and mechanical compatibility with the 0213.630TXP based on matching current rating, voltage rating, package dimensions, and response characteristics. Selection among substitutes should be based on:
Littelfuse Series 213 and 218 Substitutes: These parts offer direct compatibility with identical or equivalent electrical performance. Series 213 parts (0213.630MXP) and Series 218 parts (0218.630HXP, 0218.630MXP, 0218.630TXP) maintain the same breaking capacity and melting I²t characteristics as the primary part. The 0219.630MXAP variant offers increased breaking capacity (150A) while maintaining all other electrical parameters.
Littelfuse Series 618 Substitute: The 0618.630MXP provides equivalent electrical performance with identical breaking capacity and similar melting I²t values.
Cross-Manufacturer Substitutes: The SCHURTER 0034.3115 (FST 5x20 series) and OptiFuse TSC-630MA and TSD-630MA parts provide functional equivalence with matching current, voltage, and package specifications. OptiFuse parts carry different approval agency certifications (cULus, UL 248 for TSC-630MA; IEC 60127 for TSD-630MA) compared to the primary part.
All substitutes maintain active product status and RoHS3 compliance. Selection should account for application-specific approval agency requirements and breaking capacity specifications.
Frequently Asked Questions (FAQ)
Q: Can I substitute the 0213.630TXP with any of the listed parts?
A: Yes, all listed parts are electrically and mechanically equivalent based on matching 630mA current rating, 250V AC voltage rating, 5mm x 20mm package dimensions, and slow-blow response time. Verify that the substitute part's approval agency certifications align with your application requirements.
Q: What is the difference between the Littelfuse series (213, 218, 219XA, 618) substitutes?
A: All Littelfuse series maintain identical electrical ratings and package dimensions. The primary differences are in breaking capacity and melting I²t values. Series 219XA (0219.630MXAP) offers higher breaking capacity (150A) compared to other series (35A). Series 218 and 618 parts have slightly lower melting I²t values (4.675) compared to Series 213 (4.8).
Q: Are OptiFuse parts direct substitutes?
A: OptiFuse TSC-630MA and TSD-630MA parts match the electrical and mechanical specifications of the 0213.630TXP. However, they carry different approval agency certifications. TSC-630MA is certified to cULus and UL 248, while TSD-630MA is certified to IEC 60127. Confirm that these certifications meet your application requirements before substitution.
Q: What is the significance of Breaking Capacity differences?
A: Breaking capacity indicates the maximum fault current the fuse can safely interrupt. The 0213.630TXP has a 35A breaking capacity. The 0219.630MXAP offers 150A breaking capacity, and TSC-630MA offers 100A. Higher breaking capacity provides greater protection margin in high-fault-current applications but does not affect normal operation at rated current.
Q: Can I use the SCHURTER 0034.3115 as a substitute?
A: Yes, the SCHURTER 0034.3115 (FST 5x20 series) is electrically and mechanically equivalent with matching 630mA and 250V ratings. It carries CCC, cURus, and VDE certifications. Verify compatibility with your application's certification requirements.
Q: Do all substitutes have the same operating temperature range?
A: Yes, all listed substitutes operate across the -55°C to 125°C temperature range, matching the primary part specification.
Q: Are there inventory considerations for substitute selection?
A: Inventory levels vary among substitutes. The SCHURTER 0034.3115 has the highest inventory (10,758 pcs), while the 0218.630TXP has the lowest (792 pcs). Consider lead time and availability requirements when selecting among equivalent parts.
