Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PC06F2.5A is determined by strict equivalence across the following parameters:

• Current Rating: 2.5 A (exact match required)
• Voltage Rating: 32 V AC and 32 V DC (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)

The substitute part TR/0603FA2.5-R meets all mandatory electrical and mechanical parameters. This part maintains identical current, voltage, response time, and package specifications, ensuring direct functional equivalence in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

The TR/0603FA2.5-R is the direct functional equivalent for the obsolete PC06F2.5A. Selection of this substitute is based on the following engineering factors:

Product Status: The PC06F2.5A is classified as Obsolete. The TR/0603FA2.5-R maintains Active product status, ensuring long-term availability and manufacturing support.

Electrical Equivalence: Both parts share identical current rating (2.5 A), voltage ratings (32 V AC/DC), and response time (Fast Blow). These parameters are the primary determinants of circuit protection function.

Mechanical Compatibility: Both parts are packaged in 0603 (1608 Metric) surface mount format with identical footprint dimensions, enabling direct PCB layout compatibility.

Regulatory Compliance: The TR/0603FA2.5-R carries both CSA and UL approvals, exceeding the UL-only certification of the original part. The substitute is RoHS Compliant, meeting current environmental standards.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations. The original part was supplied in bulk packaging.

Secondary Parameter Variations: The substitute exhibits lower breaking capacity (35 A vs. 50 A), lower melting I²t (0.0625 vs. 0.10139), and higher DC cold resistance (0.037 Ohms vs. 0.021 Ohms). These variations remain within acceptable tolerance for standard circuit protection applications operating at rated current levels.

Frequently Asked Questions (FAQ)

Q: Can TR/0603FA2.5-R be used as a direct replacement for PC06F2.5A in existing designs?

A: Yes. Both parts meet identical electrical specifications (2.5 A, 32 V AC/DC, Fast Blow) and share the same 0603 (1608 Metric) surface mount package. PCB footprints are compatible. The substitute is the recommended replacement for the obsolete original part.

Q: What is the difference between the bulk packaging of PC06F2.5A and the Tape & Reel packaging of TR/0603FA2.5-R?

A: Bulk packaging is used for manual or small-quantity assembly. Tape & Reel (TR) packaging is the standard format for automated surface mount assembly lines. For production environments, Tape & Reel is the preferred format. Both contain the same component.

Q: Why does TR/0603FA2.5-R have a lower breaking capacity (35 A vs. 50 A)?

A: Breaking capacity is the maximum current the fuse can safely interrupt without damage. Both parts are rated for 2.5 A continuous operation. At the rated current, both parts function identically. The lower breaking capacity of the substitute does not affect performance in circuits designed for 2.5 A protection.

Q: Is the higher DC cold resistance of TR/0603FA2.5-R (0.037 Ohms vs. 0.021 Ohms) a concern?

A: No. At 2.5 A rated current, the voltage drop across the fuse remains negligible in both cases. The resistance difference does not impact circuit operation or protection characteristics.

Q: Does the improved Moisture Sensitivity Level (MSL 1 vs. MSL 2) of the substitute provide any advantage?

A: Yes. MSL 1 (Unlimited shelf life) provides superior storage stability compared to MSL 2 (1 Year shelf life). The substitute offers better long-term inventory management and reduced risk of moisture-related failures during storage.

Q: Are both parts RoHS compliant?

A: The TR/0603FA2.5-R is explicitly RoHS Compliant. RoHS status for the original PC06F2.5A is not specified in available documentation. For applications requiring RoHS compliance, the substitute is the appropriate choice.
