Key Parameters

Substitute Part Grouping Explanation

Substitution for the SCHURTER 2010.0020 is determined by strict equivalence in the following parameters:

• Current Rating: 2A (exact match required)
• Voltage Rating: 250VAC (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Response Time: Slow Blow (exact match required)
• Breaking Capacity: 35A (exact match required)
• Mounting Type: Requires Holder (exact match required)

All substitute parts listed maintain these core electrical and mechanical specifications. Substitute parts are classified as either direct equivalents (functionally identical) or similar alternatives (meeting all critical parameters with minor variations in secondary characteristics such as melting I²t or DC cold resistance).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred for Obsolete Part Replacement):

SCHURTER 0034.3120 is the primary substitute for the obsolete 2010.0020. Both parts are manufactured by SCHURTER Inc., share identical electrical specifications (2A, 250V, 35A breaking capacity), and maintain the same melting I²t value of 16. The 0034.3120 is currently in active production status with significantly higher inventory availability (12,003 units). This part carries CCC, cURus, and VDE approvals, with an extended operating temperature range of -55°C to 125°C.

Cross-Manufacturer Alternatives:

Littelfuse 0213002.MXP and 0218002.HXP are functionally compatible alternatives meeting all critical electrical and mechanical parameters. Both are active products with robust approval certifications (CCC, CE, CSA, PSE, SEMKO, UL, VDE). The 0213002.MXP offers the broadest approval coverage and highest inventory (17,911 units). The 0218002.HXP provides the closest melting I²t match (14.45 versus 16) and lowest DC cold resistance (0.0293 Ohms), making it suitable for applications with tight thermal or resistance specifications.

All substitute parts maintain ROHS3 compliance and are REACH unaffected, ensuring regulatory continuity.

Frequently Asked Questions (FAQ)

Q: Can I use the SCHURTER 0034.3120 as a direct replacement for the obsolete 2010.0020?

A: Yes. Both parts share identical current rating (2A), voltage rating (250V), package dimensions (5x20mm), response time (Slow Blow), breaking capacity (35A), and melting I²t (16). The 0034.3120 is the recommended substitute due to manufacturer continuity and active production status.

Q: What is the difference between the Littelfuse 0213002.MXP and 0218002.HXP?

A: Both meet all critical electrical and mechanical specifications. The primary differences are melting I²t (92.705 for 0213002.MXP versus 14.45 for 0218002.HXP) and DC cold resistance (0.0452 Ohms versus 0.0293 Ohms). The 0218002.HXP provides closer thermal characteristics to the original 2010.0020. Selection depends on application-specific thermal requirements.

Q: Are all substitute parts compatible with the same holder as the original 2010.0020?

A: Yes. All substitute parts maintain the 5mm x 20mm package dimensions and require a compatible holder, identical to the original part's mounting requirement.

Q: What certifications should I verify for my application?

A: The SCHURTER 0034.3120 carries CCC, cURus, and VDE approvals. The Littelfuse alternatives carry broader certification coverage including CCC, CE, CSA, PSE, SEMKO, UL, and VDE. Verify that the selected substitute meets your specific regional and application compliance requirements.

Q: Does the extended operating temperature range of substitute parts affect compatibility?

A: No. The substitute parts operate across -55°C to 125°C, which encompasses the original part's -40°C to 85°C range. The extended range provides additional operational margin without affecting compatibility in the original application envelope.
