Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A6T35 are qualified based on the following critical parameters:

• Current Rating: 35A (exact match required)
• Voltage Rating - AC: 600VAC (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity: 200kA (exact match required)
• Class: T (exact match required)
• Fuse Type: Cartridge (exact match required)
• Mounting: Requires Holder (mechanical compatibility)

The identified substitutes JJS-35 and JLLS035.T meet all electrical and mechanical requirements for direct replacement in applications designed for the A6T35.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with matching electrical specifications (35A, 600VAC, 200kA, Class T, Fast Blow). Selection should be based on compliance requirements and application constraints:

• A6T35 (Mersen): Select when RoHS non-compliance is acceptable and Mersen product line continuity is required.
• JJS-35 (Eaton - Bussmann Limitron™ series): Select when RoHS compliance is required and AC-only operation is specified. Carries CE, CSA, and UL certifications.
• JLLS035.T (Littelfuse POWR-GARD® series): Select when dual AC/DC voltage capability (600VAC/300VDC) is required. Carries CE, CSA, and UL certifications and meets ROHS3 compliance.

All substitutes are mechanically compatible cartridge fuses requiring standard fuse holders rated for 35A, 600VAC operation.

Frequently Asked Questions (FAQ)

Q: Can JJS-35 or JLLS035.T be used as direct replacements for A6T35?

A: Yes, both parts meet the critical electrical parameters: 35A current rating, 600VAC voltage rating, 200kA breaking capacity, Class T designation, and fast-blow response time. Mechanical compatibility is confirmed as all three require cartridge-style fuse holders.

Q: What is the difference between JJS-35 and JLLS035.T?

A: Both parts share identical AC electrical ratings (35A, 600VAC, 200kA, Class T, Fast Blow). JLLS035.T provides additional DC voltage capability (300VDC), making it suitable for applications requiring dual AC/DC operation. JJS-35 is specified for AC applications only.

Q: Are there RoHS compliance differences between the substitutes?

A: Yes. A6T35 is RoHS non-compliant. JJS-35 is RoHS Compliant. JLLS035.T is ROHS3 Compliant. Selection should align with system-level RoHS requirements.

Q: Do all parts require the same fuse holder?

A: All three parts are cartridge fuses requiring a fuse holder rated for 35A, 600VAC operation. Physical dimensions vary slightly (refer to manufacturer datasheets for exact holder compatibility verification).

Q: What certifications apply to each part?

A: A6T35 certifications are not specified in available data. JJS-35 and JLLS035.T both carry CE, CSA, and UL approvals, suitable for industrial and electrical applications in regulated markets.
