Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73B1HTTC823J is determined by strict equivalence in the following parameters:

Critical Parameters for Direct Substitution:

• Resistance value: 82 kOhms
• Tolerance: ±5%
• Power rating: 0.05W (1/20W)
• Package: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Moisture sensitivity: MSL 1 (Unlimited)

Upgrade Parameters (Higher Tolerance): Certain substitute parts offer improved tolerance specifications (±1% instead of ±5%) while maintaining all other critical parameters. These upgrades are suitable for applications requiring tighter resistance tolerances.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (±5% Tolerance):

The RK73B1HTTCM823J (KOA Speer Electronics, Inc.) is the manufacturer-recommended direct equivalent. This part maintains identical electrical specifications and is in Active product status, making it the primary choice for direct replacement in existing designs.

The AC0201JR-0782KL (YAGEO), CRCW020182K0JNED (Vishay Dale), and ERJ-1GNJ823C (Panasonic Electronic Components) are functionally equivalent alternatives. All three are Active products with matching resistance, tolerance, power rating, and package specifications. Selection among these alternatives may be based on supply availability, packaging preference, or established supplier relationships.

Operating Temperature Consideration:

The ERJ-1GNJ823C and ERJ-1GNF8202C (Panasonic) specify an operating temperature range of -55°C ~ 125°C, which is narrower than the -55°C ~ 155°C range of the primary part. These parts are suitable only for applications where the upper operating temperature does not exceed 125°C.

Upgrade Options (±1% Tolerance):

The CRCW020182K0FKED, CRCW020182K0FNED (Vishay Dale), and ERJ-1GNF8202C (Panasonic Electronic Components) offer ±1% tolerance specifications. These upgrades provide improved accuracy and are suitable for applications requiring tighter resistance tolerances. The CRCW020182K0FKED additionally features a reduced temperature coefficient of ±100ppm/°C compared to ±200ppm/°C in the original part.

All substitute parts listed are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the compliance profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can I use RK73B1HTTCM823J as a direct replacement for RK73B1HTTC823J?

A: Yes. The RK73B1HTTCM823J is the manufacturer-recommended equivalent from KOA Speer Electronics, Inc. It maintains identical electrical and mechanical specifications and is in Active product status, making it suitable for direct substitution.

Q: What is the difference between the ±5% and ±1% tolerance parts?

A: The ±1% tolerance parts (CRCW020182K0FKED, CRCW020182K0FNED, ERJ-1GNF8202C) provide tighter resistance accuracy compared to the ±5% tolerance specification of the original part. The ±1% variants are upgrades suitable for applications requiring improved precision. The CRCW020182K0FKED also features a lower temperature coefficient of ±100ppm/°C.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Most substitute parts are available in Tape & Reel (TR) packaging. The CRCW020182K0FKED is available in Cut Tape (CT) & Digi-Reel® packaging. The RK73B1HTTCM823J packaging type is not specified in the available data.

Q: Can I use ERJ-1GNJ823C or ERJ-1GNF8202C in applications requiring operation up to 155°C?

A: No. The Panasonic ERJ-1GNJ823C and ERJ-1GNF8202C are rated for operating temperatures up to 125°C only. These parts are not suitable for applications requiring operation above 125°C. Use alternatives with -55°C ~ 155°C operating range for such applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the compliance requirements of the original RK73B1HTTC823J.

Q: What is the primary reason to source an alternative to RK73B1HTTC823J?

A: The RK73B1HTTC823J is designated as "Not For New Designs," indicating it has been superseded. The RK73B1HTTCM823J is the active replacement from the same manufacturer. Alternative sources from YAGEO, Vishay Dale, and Panasonic provide additional supply chain flexibility and may offer improved specifications such as ±1% tolerance options.
