Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0293530.U are determined by equivalence across the following critical parameters:

• Current Rating: 30 A (exact match required)
• Voltage Rating - DC: 32 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: Auto Link (exact match required)
• Physical Dimensions: 0.906" L x 0.646" W x 1.205" H (exact match required)
• Series: PAL™ 293 (exact match required)

All substitute parts maintain identical electrical and mechanical specifications. Differences exist only in product status (active vs. obsolete), packaging format (bulk vs. individual), and color designation, which do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (0293030.H, 0293530.H, 0293830.H) are functionally equivalent to the 0293530.U based on identical electrical ratings, response characteristics, and physical dimensions. The primary distinction is product status: the original part is obsolete, while all substitutes are active and available.

For new designs or ongoing procurement, select from the active alternatives. The 0293530.H provides the closest match to the original part, maintaining identical color designation (green) while offering active product status and bulk packaging availability. The 0293030.H and 0293830.H are equally valid substitutes with identical electrical and mechanical performance; color variation (pink) does not affect electrical function.

All substitute parts maintain ROHS3 compliance and are manufactured by Littelfuse Inc., ensuring consistency with the original specification.

Frequently Asked Questions (FAQ)

Q: Can I use 0293030.H, 0293530.H, or 0293830.H interchangeably with 0293530.U?

A: Yes. All substitute parts maintain identical current rating (30 A), voltage rating (32 V DC), response time (slow blow), package format (Auto Link), and physical dimensions. Electrical and mechanical compatibility is complete.

Q: Does the color difference between parts affect compatibility?

A: No. Color designation is a visual identifier only and does not affect electrical performance or mechanical fit. The 0293530.H (green) and 0293030.H or 0293830.H (pink) are functionally identical.

Q: What is the difference between the packaging formats listed?

A: The original part (0293530.U) uses a standard packaging format, while substitute parts are available in bulk packaging. This affects procurement quantity and handling but not the fuse itself.

Q: Why is the original part obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. Active substitutes with identical specifications are available for continued system support.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All substitute parts maintain ROHS3 compliance, matching the original part specification.
