Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0034.4641 are qualified based on the following electrical and mechanical parameters:

• Current Rating: 1 A (exact match required)
• Voltage Rating: 125 V AC and 125 V DC (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Fuse Type: Board Mount, Cartridge Style Excluded (exact match required)
• Package / Case: Radial, Can configuration (exact match required)
• Operating Temperature Range: Minimum -55°C to maximum 125°C (substitute must meet or exceed)
• RoHS Compliance: ROHS3 Compliant (exact match required)

All substitute parts listed are manufactured by Littelfuse Inc. and belong to the MICRO™ series (272 or 273), maintaining electrical equivalence and mechanical compatibility with the original SCHURTER part.

Parameter Comparison

Engineering Selection Recommendations

All three Littelfuse substitute parts (0272001.H, 0272001.V, and 0273001.V) are active products with current manufacturing status, providing superior availability compared to the obsolete SCHURTER 0034.4641. All substitutes maintain electrical equivalence across the critical parameters: 1 A current rating, 125 V AC/DC voltage rating, and fast blow response time.

The Littelfuse MICRO™ 272 series (0272001.H and 0272001.V) and MICRO™ 273 series (0273001.V) all carry CSA, QPL, and UL approvals, providing enhanced regulatory compliance documentation. All substitute parts are ROHS3 compliant and REACH unaffected, matching the environmental compliance profile of the original part.

Physical dimensions vary slightly among substitutes. The MICRO™ 272 variants are smaller (0.235" Dia x 0.287" H), while the MICRO™ 273 variant (0273001.V) is closer in size to the original (0.250" Dia x 0.350" H). PCB layout and mounting hole spacing must be verified during design integration to ensure mechanical compatibility.

The MICRO™ 273 variant operates to -55°C ~ 85°C, which is narrower than the original -55°C ~ 125°C range. Applications requiring operation above 85°C must use MICRO™ 272 variants to maintain full temperature specification compliance.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0272001.H, 0272001.V, and 0273001.V be used interchangeably with the SCHURTER 0034.4641?

A: All three Littelfuse parts are electrically equivalent, meeting the 1 A, 125 V AC/DC, fast blow specifications. However, physical dimensions differ. The MICRO™ 272 variants are smaller, while the MICRO™ 273 is closer in size to the original. PCB layout compatibility must be confirmed before substitution.

Q: What is the difference between the Littelfuse 0272001.H and 0272001.V?

A: Both parts are identical in electrical specifications and dimensions. The designation difference (H vs. V) indicates packaging or tape orientation variants. Both are active products with equivalent availability and performance.

Q: Does the MICRO™ 273 variant (0273001.V) have any limitations compared to the MICRO™ 272 variants?

A: The MICRO™ 273 operates to a maximum temperature of 85°C, compared to 125°C for the MICRO™ 272 series. Applications requiring operation above 85°C must use the MICRO™ 272 variants to maintain full temperature specification compliance.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the environmental compliance profile of the original SCHURTER 0034.4641.

Q: What regulatory approvals do the Littelfuse substitutes carry?

A: All three Littelfuse substitute parts carry CSA, QPL, and UL approvals, providing enhanced regulatory documentation compared to the original part.

Q: How do the physical dimensions affect PCB design?

A: The MICRO™ 272 variants (0.235" Dia x 0.287" H) are smaller than the original (0.252" Dia x 0.346" H), while the MICRO™ 273 (0.250" Dia x 0.350" H) is nearly identical in size. Mounting hole spacing and clearance requirements must be verified during design integration to ensure mechanical fit.
