1N4942GP-TP Equivalent & Substitute Parts

Part Overview

The 1N4942GP-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 200 V DC reverse voltage and 1 A average rectified current in a through-hole DO-41 package. This component is classified as Active and is ROHS3 compliant. Substitute parts are identified based on matching electrical specifications and mechanical compatibility within the general-purpose rectifier diode category. Alternative components may be required due to packaging format availability, inventory considerations, or supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1N4942GP-TP are qualified based on the following electrical and mechanical parameters:

Electrical Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
• Reverse Recovery Time (trr): 150 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 200 V
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Matching Criteria:

• Mounting Type: Through Hole
• Package / Case: DO-204AL, DO-41, Axial
• Operating Temperature - Junction: -55°C to 150°C

Compliance Matching Criteria:

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

The substitute parts FR103G A0G and FR103G R0G meet all electrical specifications and operate within the same temperature range. Both are ROHS3 compliant and MSL 1 rated. Packaging format differs between the main part (Tape & Reel) and substitutes (Cut Tape and Tape & Reel variants), but mechanical compatibility is maintained through identical DO-41/DO-204AL package geometry.

Parameter Comparison

Engineering Selection Recommendations

1N4942GP-TP (Primary Component) The 1N4942GP-TP is the primary specification and remains the preferred selection where availability permits. This component is Active status with full manufacturer support and is available in Tape & Reel packaging format.

FR103G A0G (Substitute - Cut Tape Format) The FR103G A0G is a direct electrical equivalent with identical voltage, current, and recovery time specifications. This substitute is supplied in Cut Tape (CT) packaging rather than Tape & Reel format. Selection of this variant is appropriate when Cut Tape packaging is compatible with assembly processes or when inventory availability of this format is advantageous. Product status is Active with full manufacturer support.

FR103G R0G (Substitute - Tape & Reel Format) The FR103G R0G is a direct electrical equivalent supplied in Tape & Reel (TR) packaging, matching the format of the primary component. This substitute is listed as Discontinued at DiGi Electronics, indicating reduced availability through standard distribution channels. Selection of this variant is appropriate only when alternative sources confirm current availability and when packaging format preference aligns with assembly requirements.

All three components are ROHS3 compliant, MSL 1 rated, and operate within the identical temperature range of -55°C to 150°C. Capacitance specification differs slightly (15 pF for 1N4942GP-TP versus 10 pF for FR103G variants), but this parameter does not affect substitution eligibility within the general-purpose rectifier diode category.

Frequently Asked Questions (FAQ)

Q: Can FR103G A0G and FR103G R0G be used interchangeably with 1N4942GP-TP?

A: Yes. Both FR103G variants meet all electrical specifications for the 1N4942GP-TP, including voltage rating (200 V), current rating (1 A), forward voltage drop (1.3 V @ 1 A), and reverse recovery time (150 ns). The primary difference is packaging format: FR103G A0G is supplied in Cut Tape, while FR103G R0G is supplied in Tape & Reel, matching the original component format.

Q: What is the significance of the capacitance difference between the main part and substitutes?

A: The 1N4942GP-TP specifies 15 pF capacitance at 4V, 1MHz, while both FR103G variants specify 10 pF at the same conditions. This 5 pF difference does not affect functional compatibility in general-purpose rectifier applications and does not disqualify these parts as electrical equivalents.

Q: Are there packaging considerations when substituting these diodes?

A: All three components use through-hole mounting in DO-41/DO-204AL axial packages with identical physical dimensions. Mechanical compatibility is maintained across all three parts. The distinction lies in supply format: Tape & Reel (TR) for automated assembly processes, and Cut Tape (CT) for manual or semi-automated assembly. Verify that your assembly process accommodates the selected packaging format.

Q: What is the product status of each substitute?

A: The 1N4942GP-TP and FR103G A0G are both Active products with ongoing manufacturer support. The FR103G R0G is listed as Discontinued at DiGi Electronics, indicating reduced availability through this distribution channel. Confirm current availability through alternative suppliers before selecting FR103G R0G.

Q: Are all three components RoHS compliant?

A: Yes. The 1N4942GP-TP, FR103G A0G, and FR103G R0G are all ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting environmental and regulatory requirements for industrial and commercial applications.

Q: What electrical parameters determine substitution eligibility?

A: Substitution is based on matching: Voltage - DC Reverse (200 V), Current - Average Rectified (1 A), Voltage - Forward (1.3 V @ 1 A), Reverse Recovery Time (150 ns), Current - Reverse Leakage (5 µA @ 200 V), and Speed Classification (Fast Recovery ≤ 500ns, > 200mA). All three components meet these criteria.
