Key Parameters

Substitute Part Grouping Explanation

Substitution of the FR1004-AP is determined by electrical and mechanical parameter equivalence. The following criteria establish direct substitutability:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 10 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 10 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 150 ns
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters (Must Match):

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

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The FR1004GP-AP meets all substitution criteria and is classified as an active product, providing supply continuity for the obsolete FR1004-AP.

Parameter Comparison

Engineering Selection Recommendations

The FR1004GP-AP is a direct electrical and mechanical equivalent to the FR1004-AP. Both components share identical electrical specifications across all critical parameters: reverse voltage rating, average rectified current, forward voltage drop, recovery time characteristics, and operating temperature range. Both are packaged in R-6 axial through-hole configuration and comply with ROHS3 standards.

The primary distinction is product status: FR1004-AP is obsolete while FR1004GP-AP is active. The FR1004GP-AP additionally demonstrates improved reverse leakage current performance (5 µA versus 10 µA at 400 V), which represents a performance enhancement without deviation from the original specification envelope.

For new designs and production applications requiring the FR1004-AP electrical and mechanical characteristics, the FR1004GP-AP is the appropriate selection. For existing inventory management or repair applications, the FR1004-AP remains functionally valid until depletion, after which transition to FR1004GP-AP is required.

Frequently Asked Questions (FAQ)

Q: Can FR1004GP-AP be used as a direct replacement for FR1004-AP in existing designs?

A: Yes. The FR1004GP-AP meets all electrical and mechanical specifications of the FR1004-AP. Both components are rated for 400 V reverse voltage, 10 A average rectified current, and share identical forward voltage, recovery time, and thermal characteristics. The R-6 axial through-hole package is identical, enabling direct board-level substitution without layout modification.

Q: What is the significance of the different reverse leakage current values?

A: The FR1004GP-AP exhibits 5 µA reverse leakage at 400 V compared to 10 µA for the FR1004-AP. This represents improved leakage performance in the substitute part. Both values remain within acceptable operating parameters for general-purpose rectification applications. The lower leakage in FR1004GP-AP does not introduce incompatibility; it represents a performance enhancement.

Q: Why is FR1004-AP classified as obsolete?

A: FR1004-AP is designated obsolete by the manufacturer. The FR1004GP-AP is the active equivalent part maintained in current production. For new procurement, FR1004GP-AP should be specified to ensure supply continuity and access to manufacturer support.

Q: Are there any package or mounting differences between these parts?

A: No. Both FR1004-AP and FR1004GP-AP use identical R-6 axial through-hole packaging. No modifications to PCB footprints, lead spacing, or mounting procedures are required when transitioning between these parts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both FR1004-AP and FR1004GP-AP are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage or assembly.

Q: What is the base product number relationship?

A: Both FR1004-AP and FR1004GP-AP share the base product number FR1004, indicating they are part of the same product family with identical core electrical specifications. The suffix designations (-AP and -GP-AP) reflect packaging or manufacturing variants within this family.
