FR156-AP Equivalent & Substitute Parts

Part Overview

The FR156-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 800 V DC reverse voltage and 1.5 A average rectified current in a DO-15 through-hole package. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain identical electrical performance characteristics and mechanical compatibility to ensure direct replacement capability in existing circuit applications.

Substitute Part Grouping Explanation

Substitute parts for the FR156-AP are classified based on strict electrical and mechanical parameter equivalence. All substitute candidates must satisfy the following criteria:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 800 V
• Current - Average Rectified (Io): 1.5 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1.5 A
• Reverse Recovery Time (trr): 500 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 800 V
• Capacitance @ Vr, F: 20 pF @ 4V, 1MHz
• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, Axial
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Standard
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Substitutes are grouped into two categories: direct manufacturer equivalents from Micro Commercial Co and parametric equivalents from alternative manufacturers. All listed substitutes maintain complete electrical and mechanical compatibility with the original FR156-AP specification.

Engineering Selection Recommendations

FR156GP-AP (Direct Manufacturer Equivalent)

The FR156GP-AP is the primary substitute for the obsolete FR156-AP. Both components are manufactured by Micro Commercial Co and share identical electrical specifications and package configurations. The FR156GP-AP maintains active product status, ensuring long-term availability and supply chain continuity. This part is recommended for direct replacement in applications where the original FR156-AP is no longer procurable. All electrical parameters, thermal characteristics, and compliance certifications are equivalent.

FR156G A0G (Parametric Equivalent - Taiwan Semiconductor Corporation)

The FR156G A0G provides parametric equivalence with complete electrical and mechanical compatibility. Manufactured by Taiwan Semiconductor Corporation, this component maintains active product status and satisfies all electrical performance requirements. This substitute is suitable for applications requiring alternative sourcing or where Taiwan Semiconductor Corporation components are preferred within supply chain specifications.

FR156GHA0G (Parametric Equivalent - Automotive Grade)

The FR156GHA0G is an automotive-qualified variant manufactured by Taiwan Semiconductor Corporation, certified to AEC-Q101 standards. This component maintains all electrical and mechanical equivalence to the FR156-AP while providing automotive-grade qualification. Selection of this part is appropriate for automotive applications or systems requiring AEC-Q101 compliance. All electrical parameters remain identical to the standard variants.

All substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original FR156-AP compliance profile.

Frequently Asked Questions (FAQ)

Q: Can FR156GP-AP be used as a direct replacement for FR156-AP?

A: Yes. The FR156GP-AP is manufactured by the same supplier (Micro Commercial Co) and maintains identical electrical specifications, forward voltage characteristics, reverse recovery time, leakage current, and package configuration. The primary distinction is product status: FR156GP-AP is active while FR156-AP is obsolete.

Q: What is the difference between the Taiwan Semiconductor Corporation variants (FR156G A0G and FR156GHA0G)?

A: Both Taiwan Semiconductor Corporation parts maintain identical electrical parameters and mechanical compatibility. The FR156GHA0G includes automotive-grade qualification and AEC-Q101 certification, making it suitable for automotive applications. Selection between these variants depends on application requirements and compliance specifications.

Q: Are all substitute parts compatible with the original DO-15 package footprint?

A: Yes. All substitute parts are specified for DO-204AC, DO-15, Axial package configuration with through-hole mounting type. Package dimensions and pin configurations are equivalent, enabling direct PCB footprint compatibility.

Q: Do the substitute parts maintain the same thermal operating range?

A: Yes. All substitute parts operate across the identical junction temperature range of -55°C to 150°C, matching the FR156-AP specification.

Q: Are there compliance or certification differences between the substitutes?

A: All parts are ROHS3 compliant with MSL rating 1 (Unlimited). The FR156GHA0G includes additional automotive-grade qualification and AEC-Q101 certification. Standard industrial applications can use any of the three substitutes; automotive applications should specify FR156GHA0G.

Q: What electrical parameters must remain constant for substitution validity?

A: The following parameters must match exactly: 800 V reverse voltage rating, 1.5 A average rectified current, 1.3 V maximum forward voltage at 1.5 A, 500 ns reverse recovery time, 5 µA reverse leakage current at 800 V, and 20 pF capacitance at 4V, 1MHz. All substitute parts satisfy these requirements.
