Key Parameters

Substitute Part Grouping Explanation

Substitution of the FR1003-AP is determined by electrical and mechanical parameter equivalence within the rectifier diode category. The following parameters establish substitution validity:

Electrical Parameters (Critical):

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 10 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 10 A
• Reverse Recovery Time (trr): 150 ns
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Critical):

• Mounting Type: Through Hole
• Package / Case: R-6, Axial

Environmental & Compliance Parameters:

• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all critical electrical and mechanical parameters, along with equivalent environmental and compliance specifications, are classified as direct substitutes. Variations in reverse leakage current within the same voltage and current ratings do not disqualify substitution eligibility when all other parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

The FR1003GP-AP is a direct electrical and mechanical equivalent to the FR1003-AP. Both parts share identical voltage ratings (200 V DC reverse), current ratings (10 A average rectified), forward voltage characteristics (1.3 V @ 10 A), and recovery time specifications (150 ns). Package configuration, mounting type, and thermal operating range are identical across both parts.

The primary distinction between the two parts is product status: the FR1003-AP is classified as obsolete, while the FR1003GP-AP maintains active status. The FR1003GP-AP additionally demonstrates improved reverse leakage performance (5 µA @ 200 V versus 10 µA @ 200 V), representing a beneficial characteristic variation that does not compromise substitution eligibility.

Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity classification, ensuring equivalent environmental and regulatory compliance. Selection of the FR1003GP-AP for new designs and procurement activities is supported by its active product status and equivalent electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the FR1003GP-AP directly replace the FR1003-AP in existing circuit designs?

A: Yes. The FR1003GP-AP meets all critical electrical parameters of the FR1003-AP, including voltage rating (200 V), current rating (10 A), forward voltage (1.3 V @ 10 A), and recovery time (150 ns). Package configuration and mounting type are identical (R-6 axial through-hole). Direct substitution is supported without circuit modification.

Q: What is the significance of the lower reverse leakage current in the FR1003GP-AP?

A: The FR1003GP-AP exhibits 5 µA reverse leakage at 200 V, compared to 10 µA in the FR1003-AP. This represents improved leakage performance and does not restrict substitution. Lower reverse leakage may provide marginal benefits in high-impedance circuit applications but does not alter fundamental substitution compatibility.

Q: Why is the FR1003-AP classified as obsolete?

A: The FR1003-AP carries an obsolete product status designation. The FR1003GP-AP serves as the active equivalent, maintaining identical electrical and mechanical specifications while offering continued manufacturer support and availability.

Q: Are there any compliance or certification differences between these parts?

A: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) classification. The FR1003GP-AP includes REACH Unaffected status documentation. Both parts carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: What mounting considerations apply to these rectifier diodes?

A: Both parts utilize through-hole mounting in R-6 axial package configuration. This package type is suitable for insertion into standard PCB through-hole pads with axial lead spacing. No special mounting equipment or techniques are required beyond standard through-hole assembly processes.

Q: Can the FR1003GP-AP operate across the same temperature range as the FR1003-AP?

A: Yes. Both parts maintain identical operating temperature ranges of -55°C to 150°C junction temperature. Thermal performance and derating characteristics are equivalent across the specified operating envelope.
