FR505-AP Equivalent & Substitute Parts

Part Overview

The FR505-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 600 V DC reverse voltage and 5 A average rectified current in a DO-201AD axial through-hole package. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing procurement and design continuity. The FR505-AP operates across a junction temperature range of -55°C to 150°C and complies with ROHS3 standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FR505-AP is determined by electrical and mechanical parameter equivalence. The following criteria establish direct substitutability:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 5 A
• Voltage - Forward (Vf) (Max) @ If: 1.35 V @ 5 A
• Reverse Recovery Time (trr): 250 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 600 V
• Capacitance @ Vr, F: 65 pF @ 4V, 1MHz
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Must Match):

• Package / Case: DO-201AD, Axial
• Mounting Type: Through Hole

Compliance & Status:

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

The FR505GP-AP meets all electrical and mechanical equivalence criteria and is classified as an active product, making it a direct substitute for the obsolete FR505-AP.

Parameter Comparison

Engineering Selection Recommendations

The FR505GP-AP is the direct equivalent substitute for the FR505-AP. Both parts are manufactured by Micro Commercial Co and share identical electrical specifications, mechanical packaging, and compliance certifications. The primary distinction is product status: the FR505-AP is obsolete, while the FR505GP-AP is active and available for procurement.

Selection of the FR505GP-AP for new designs or replacement applications is supported by:

• Complete electrical parameter equivalence across all rated conditions
• Identical DO-201AD axial through-hole package geometry and pin configuration
• Matching ROHS3 compliance and MSL classification
• Active product status ensuring supply chain continuity and manufacturing support

No design modifications, circuit adjustments, or additional validation are required when substituting the FR505GP-AP for the FR505-AP in existing applications.

Frequently Asked Questions (FAQ)
