Parameter Comparison

Engineering Selection Recommendations

The 0293575.H is the direct equivalent substitute for the obsolete 0293575.U. Both parts are manufactured by Littelfuse Inc. and share identical electrical specifications (75A, 32V DC), mechanical form factor (Auto Link package), and regulatory compliance (ROHS3 Compliant).

The primary distinction is product status: the 0293575.U is obsolete, while the 0293575.H maintains active production status. This ensures long-term availability and supply chain reliability for ongoing automotive fuse protection applications.

Both parts meet identical compliance requirements and carry the same Moisture Sensitivity Level (MSL 1 - Unlimited), confirming full interchangeability in automotive electrical protection circuits.

Frequently Asked Questions (FAQ)

Q: Can the 0293575.H directly replace the 0293575.U in automotive applications?

A: Yes. The 0293575.H is a direct parametric equivalent. All critical electrical parameters (75A current rating, 32V DC voltage rating), mechanical specifications (Auto Link package, identical dimensions), and response characteristics (Slow Blow) are identical. Both parts are ROHS3 compliant and carry the same MSL rating.

Q: What is the difference between the 0293575.U and 0293575.H?

A: The primary difference is product status. The 0293575.U is obsolete, while the 0293575.H is in active production. The packaging designation differs (0293575.U shows "-" while 0293575.H specifies "Bulk"), but electrical and mechanical specifications are identical.

Q: Does the Auto Link package format affect substitutability?

A: No. Both parts use the identical Auto Link package format and require the same holder type. The physical dimensions are identical (0.906" L x 0.646" W x 1.205" H / 23.00mm x 16.40mm x 30.60mm), ensuring mechanical compatibility in existing fuse holder installations.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, MSL 1 (Unlimited), ECCN EAR99, and HTSUS 8536.10.0020. Regulatory and environmental compliance is equivalent.

Q: Why should I transition from the 0293575.U to the 0293575.H?

A: The 0293575.U is obsolete, creating supply chain risk. The 0293575.H is the active equivalent part, ensuring continued availability for replacement, maintenance, and new production applications without any functional or compliance compromise.
