Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PC06F750MA is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Current Rating: 750 mA (exact match required)
• Voltage Rating - AC: 32 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)

Allowable Variation Parameters:

• Voltage Rating - DC: May exceed 32 V (higher ratings provide backward compatibility)
• Breaking Capacity: Must meet or exceed 50 A
• Approval Agency: Must include UL certification; additional certifications acceptable
• Product Status: Active status preferred for ongoing availability

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

TR/0603FA750-R (Eaton - Electronics Division):

This substitute maintains identical electrical specifications to the PC06F750MA across all critical parameters: 750 mA current rating, 32 V AC/DC voltage ratings, and fast blow response. The TR/0603FA750-R carries active product status, ensuring long-term supply availability. It includes both CSA and UL certifications, exceeding the original part's UL-only approval. The component is RoHS Compliant and features improved moisture sensitivity (MSL 1 vs. MSL 2), providing enhanced reliability in storage and handling. Packaging is supplied in Tape & Reel format with 10,400 units in stock. This substitute is the preferred choice for direct replacement in applications where the original PC06F750MA is no longer available.

0438.750WR (Littelfuse Inc.):

This substitute matches all critical electrical parameters with the exception of DC voltage rating, which is rated at 63 V compared to the original 32 V DC specification. The higher DC voltage rating provides additional design margin and backward compatibility for applications operating at or below 32 V DC. The 0438.750WR carries active product status with CSA and UL certifications. It is ROHS3 Compliant and REACH Unaffected, meeting current environmental compliance standards. Operating temperature range extends to 150°C, exceeding the original specification. Packaging is supplied in Tape & Reel format with 36,100 units in stock. This substitute is suitable for applications where the elevated DC voltage rating does not create design conflicts.

Frequently Asked Questions (FAQ)

Q: Can TR/0603FA750-R be used as a direct replacement for PC06F750MA?

A: Yes. The TR/0603FA750-R matches all critical electrical and mechanical parameters: 750 mA current rating, 32 V AC/DC voltage ratings, fast blow response, 0603 package, and surface mount configuration. Both components are manufactured by Eaton - Electronics Division. The substitute carries active product status and includes UL certification.

Q: What is the primary difference between the two substitute parts?

A: The primary difference is the DC voltage rating. TR/0603FA750-R maintains the original 32 V DC specification, while 0438.750WR is rated for 63 V DC. Both parts meet the 750 mA current requirement and 32 V AC specification. The 0438.750WR is manufactured by Littelfuse Inc., whereas TR/0603FA750-R is manufactured by Eaton - Electronics Division.

Q: Is the higher DC voltage rating of 0438.750WR a concern for applications designed for 32 V DC?

A: No. A fuse rated for 63 V DC is suitable for applications operating at 32 V DC. The higher voltage rating provides additional design margin and does not create compatibility issues in circuits designed for lower voltage operation.

Q: What packaging formats are available for the substitute parts?

A: Both substitute parts are supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes. The original PC06F750MA was supplied in bulk packaging. Tape & Reel format is standard for high-volume production environments.

Q: Are the substitute parts RoHS compliant?

A: Yes. TR/0603FA750-R is RoHS Compliant. 0438.750WR is ROHS3 Compliant. Both meet current environmental compliance requirements. The original PC06F750MA RoHS status was not specified.

Q: What is the moisture sensitivity level (MSL) for the substitute parts?

A: Both substitute parts carry MSL 1 (Unlimited), indicating superior moisture resistance compared to the original PC06F750MA, which carries MSL 2 (1 Year). MSL 1 rating allows extended storage without desiccant packaging requirements.

Q: Are both substitute parts UL certified?

A: Yes. TR/0603FA750-R carries CSA and UL certifications. 0438.750WR carries CSA and UL certifications. Both exceed the original PC06F750MA's UL-only certification.

Q: What is the inventory status for the substitute parts?

A: TR/0603FA750-R has 10,400 units in stock. 0438.750WR has 36,100 units in stock. Both parts are available in active product status with established supply chains.
