Engineering Selection Recommendations
Eaton - Electronics Division Series (GDA and S501): The BK/GDA-5A, BK/S501-5-R, BK1/S501-5-R, and S501-5-R variants are direct equivalents manufactured by Eaton. These parts maintain identical electrical characteristics and are suitable for direct substitution. The S501 series variants offer expanded regional certifications including BSI, cULus, MITI/JET, and VDE, providing broader compliance coverage for international applications. All Eaton variants are ROHS3 compliant.
SCHURTER Inc. 0001.1011: This part is a full parametric equivalent with identical breaking capacity and melting I²t within acceptable tolerance. The SCHURTER part specifies an operating temperature range of -55°C to 125°C, providing defined thermal performance. Certifications include CCC, cURus, KC, PSE/JET, and VDE. This part is suitable for applications requiring extended temperature specification.
Littelfuse Inc. Series 216 (0216005.HXP, 0216005.MXP, 0216005.VXP): All three Littelfuse variants are parametric equivalents with melting I²t of 27.46 and DC cold resistance of 0.0183 Ohms. These parts offer the broadest certification coverage, including BSI, CCC, CE, CSA, KC, PSE, SEMKO, UR, and VDE. Operating temperature range is -55°C to 125°C. The three variants differ only in packaging designation (HXP, MXP, VXP) and represent the same electrical component. Littelfuse parts are ROHS3 compliant and REACH unaffected.
OptiFuse FCC-5A: The FCC-5A has a reduced breaking capacity of 200 A compared to the 1.5 kA specification of the main part. This part is suitable only for applications where the lower breaking capacity is acceptable. Certifications are limited to cULus and UL 248. This part is not recommended as a primary substitute due to breaking capacity limitation.
OptiFuse FCD-5A: The FCD-5A maintains the 1.5 kA breaking capacity and is suitable for direct substitution. This part specifies both 250 V AC and 250 V DC voltage ratings. Operating temperature range is -55°C to 125°C. Compliance is based on IEC 60127. This part offers the highest inventory availability (4286 pieces) and is ROHS3 compliant.
Certification Alignment: For applications requiring specific regional certifications, the Littelfuse 216 series and Eaton S501 series provide the most comprehensive approval coverage. The GDA series maintains the original certification set (CCC, CSA, IMQ, SEMKO, UR).
Frequently Asked Questions (FAQ)
Q: Can the GDA-5A be directly replaced with any of the listed substitute parts?
A: All listed substitute parts maintain identical current rating (5 A), voltage rating (250 V AC), package dimensions (5mm x 20mm), and response time (fast blow). Direct substitution is supported for all parts except FCC-5A, which has a reduced breaking capacity of 200 A versus the specified 1.5 kA. Verify application breaking capacity requirements before selecting FCC-5A.
Q: What is the difference between the Eaton GDA and S501 series?
A: Both series are manufactured by Eaton and maintain identical electrical specifications for the 5 A, 250 V rating. The S501 series includes expanded regional certifications (BSI, cULus, MITI/JET, VDE) compared to the GDA series (CCC, CSA, IMQ, SEMKO, UR). Selection between series depends on regional compliance requirements.
Q: Are the three Littelfuse 216 variants (HXP, MXP, VXP) electrically identical?
A: Yes. The 0216005.HXP, 0216005.MXP, and 0216005.VXP are electrically identical with the same current rating, voltage rating, breaking capacity, melting I²t (27.46), and DC cold resistance (0.0183 Ohms). The designations represent different packaging or distribution channel variants. All three are ROHS3 compliant and REACH unaffected.
Q: What is the significance of melting I²t values in the parameter comparison?
A: Melting I²t is a thermal characteristic that defines the energy required to melt the fuse element. The GDA-5A specifies 25, while substitutes range from 22.303 to 30.8. These variations are within acceptable tolerance for fast-blow ceramic cartridges and do not affect functional equivalence for standard 5 A circuit protection applications.
Q: Does the SCHURTER 0001.1011 have any limitations compared to other substitutes?
A: The SCHURTER part is a full parametric equivalent with no functional limitations. It specifies an operating temperature range of -55°C to 125°C and includes certifications for CCC, cURus, KC, PSE/JET, and VDE. Selection depends on regional certification requirements and temperature operating conditions.
Q: Why does the OptiFuse FCC-5A have a lower breaking capacity?
A: The FCC-5A specifies a breaking capacity of 200 A, compared to 1.5 kA for the main part and other substitutes. This represents a design difference in the fuse element construction. The FCC-5A is suitable only for applications where the lower breaking capacity meets circuit protection requirements. Verify application specifications before selection.
Q: Which substitute part has the highest inventory availability?
A: The OptiFuse FCD-5A has the highest inventory with 4286 pieces in stock. The SCHURTER 0001.1011 is the second highest with 3219 pieces. Both parts are suitable for direct substitution and offer immediate availability for high-volume requirements.
Q: Are all substitute parts RoHS3 compliant?
A: All substitute parts listed are RoHS3 compliant. The original GDA-5A does not specify RoHS status in the provided data. For applications requiring RoHS3 compliance, any of the listed substitutes are suitable.
Q: What certifications are required for international applications?
A: Certification requirements vary by region. The Littelfuse 216 series offers the broadest coverage with BSI, CCC, CE, CSA, KC, PSE, SEMKO, UR, and VDE approvals. The Eaton S501 series includes BSI, CCC, CSA, cULus, IMQ, MITI/JET, SEMKO, and VDE. Verify specific regional requirements before final part selection.
