FR1K-TP Equivalent & Substitute Parts

Part Overview

The FR1K-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 800 V DC reverse voltage and 1 A average rectified current in a surface mount DO-214AA (SMB) package. This part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing production and procurement requirements. Substitute parts must maintain electrical and mechanical compatibility while meeting current availability and compliance standards.

Substitute Part Grouping Explanation

Substitute parts for the FR1K-TP are classified based on strict electrical and mechanical parameter alignment. All substitute candidates maintain the following critical parameters:

• Voltage - DC Reverse (Vr) (Max): 800 V
• Current - Average Rectified (Io): 1 A
• Speed Classification: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Reverse Recovery Time (trr): 500 ns
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -50°C ~ 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitutes are grouped into two categories:

Direct Manufacturer Substitutes: Parts from the same manufacturer (Micro Commercial Co) with identical base product designation but different packaging configurations.

Parametric Equivalents: Parts from alternative manufacturers (SMC Diode Solutions, Panjit International Inc.) that meet all critical electrical specifications and package requirements.

Parameter Comparison

Engineering Selection Recommendations

FR1K-LTP (Micro Commercial Co): This direct manufacturer substitute is the primary alternative for FR1K-TP replacement. Both parts share identical electrical specifications and are manufactured by the same supplier. FR1K-LTP is active in production status and available in Tape & Reel packaging, suitable for automated assembly processes. Selection of FR1K-LTP eliminates supplier qualification requirements and maintains design continuity with the original component family.

FR1K (SMC Diode Solutions): This parametric equivalent meets all critical electrical and mechanical requirements. The part is active in production and available in Tape & Reel packaging. REACH status differs from the main part (REACH Affected vs. REACH Unaffected), requiring compliance verification for applications subject to REACH regulations. Capacitance specification is lower (10 pF vs. 12 pF), which may be advantageous in certain circuit topologies.

FR1K_R1_00001 (Panjit International Inc.): This parametric equivalent satisfies all electrical and mechanical substitution criteria. The part is active in production with the highest inventory availability (1826 Pcs). Reverse leakage current is superior (1 µA vs. 5 µA), providing enhanced performance in low-leakage applications. Supplier qualification is required for first-time use.

Frequently Asked Questions (FAQ)

Q: Can FR1K-LTP be used as a direct replacement for FR1K-TP in existing designs?

A: Yes. FR1K-LTP maintains identical electrical specifications (800 V, 1 A, 500 ns recovery time) and package configuration (DO-214AA, SMB). The primary difference is packaging format (Tape & Reel vs. bulk), which does not affect electrical performance or PCB assembly compatibility.

Q: What are the key differences between the three substitute options?

A: All three substitutes meet the core electrical requirements (800 V, 1 A, 500 ns recovery time, DO-214AA package). FR1K-LTP is from the original manufacturer. FR1K (SMC) and FR1K_R1_00001 (Panjit) are from alternative manufacturers. Minor variations exist in capacitance (10-15 pF range) and reverse leakage current (1-5 µA range), which remain within acceptable tolerances for general-purpose rectification applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant certification. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements.

Q: Does REACH status affect part selection?

A: REACH status differs between suppliers. FR1K-TP and FR1K-LTP are REACH Unaffected. FR1K (SMC) is REACH Affected. Applications subject to REACH regulations must verify compliance requirements with the specific supplier and regulatory jurisdiction.

Q: Can these parts be used interchangeably in automated assembly?

A: FR1K-LTP, FR1K (SMC), and FR1K_R1_00001 are all available in Tape & Reel packaging, suitable for automated pick-and-place assembly. FR1K-TP is supplied in bulk packaging and requires manual handling or tape conversion for automated processes.

Q: What is the significance of the capacitance variation (10-15 pF)?

A: Capacitance variation across the substitute range (10 pF to 15 pF at 4V, 1MHz) falls within typical manufacturing tolerances for general-purpose rectifier diodes. Circuit designs with specific capacitance requirements should reference the detailed datasheet for the selected substitute part.

Q: Which substitute offers the best reverse leakage performance?

A: FR1K_R1_00001 (Panjit) specifies 1 µA reverse leakage at 800 V, compared to 5 µA for other parts. This lower leakage current provides enhanced performance in applications requiring minimal reverse current, such as precision rectification or high-impedance circuits.
