Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73B1HTTC162J is determined by strict equivalence in the following parameters:

Primary Substitution Criteria (Must Match):

• Resistance value: 1.6 kOhms
• Package / Case: 0201 (0603 Metric)
• Power rating: 0.05W (1/20W)
• Composition: Thick Film
• Tolerance: ±5% (for direct equivalents) or ±1% (for upgraded alternatives)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Secondary Compatibility Parameters:

• Temperature Coefficient: ±200ppm/°C (standard) or ±100ppm/°C (upgraded)
• Operating Temperature Range: -55°C minimum and 155°C maximum (or -55°C to 125°C for some alternatives)

Substitute parts are grouped into three categories: (1) Direct Manufacturer Equivalents with identical tolerance and temperature specifications; (2) MFR Recommended Alternatives from the original manufacturer with active product status; and (3) Upgraded Alternatives with improved tolerance (±1%) or temperature coefficient specifications that provide enhanced performance while maintaining full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Specifications):

The RK73B1HTTCM162J from KOA Speer Electronics is the manufacturer-recommended direct equivalent. It maintains all electrical and mechanical specifications of the original part while offering Active product status, ensuring long-term availability and supply chain continuity.

For cross-manufacturer direct equivalents with ±5% tolerance and ±200ppm/°C temperature coefficient, the following parts are suitable:

• AC0201JR-071K6L (YAGEO) with extended temperature range to 155°C
• CRCW02011K60JNED (Vishay Dale) with extended temperature range to 155°C
• ERJ-1GNJ162C (Panasonic Electronic Components) with temperature range to 125°C
• RC0201JR-071K6L (YAGEO) with temperature range to 125°C

All direct equivalents are ROHS3 compliant with MSL 1 rating and maintain the 0201 package form factor.

Upgraded Alternatives (Enhanced Tolerance):

For applications requiring improved tolerance and temperature stability, upgraded parts with ±1% tolerance are available:

• CRCW02011K60FKED (Vishay Dale): ±1% tolerance, ±100ppm/°C, -55°C to 155°C
• CRCW02011K60FNED (Vishay Dale): ±1% tolerance, ±200ppm/°C, -55°C to 155°C
• ERJ-1GNF1601C (Panasonic Electronic Components): ±1% tolerance, ±200ppm/°C, -55°C to 125°C
• RC0603F162CS (Samsung Electro-Mechanics): ±1% tolerance, ±250ppm/°C, -55°C to 125°C

Upgraded alternatives provide superior performance characteristics while maintaining full backward compatibility with the original RK73B1HTTC162J footprint and electrical interface.

Availability and Supply Considerations:

ERJ-1GNF1601C (Panasonic) offers the highest inventory level (98,302 pcs) among upgraded alternatives. CRCW02011K60FKED (Vishay Dale) provides the best combination of high inventory (20,674 pcs), extended temperature range to 155°C, and superior temperature coefficient (±100ppm/°C).

MCR006YRTJ162 (Rohm Semiconductor) is noted as discontinued at DiGi Electronics and should not be selected for new procurement despite available inventory.

Frequently Asked Questions (FAQ)

Q: Can I use a ±1% tolerance part as a direct replacement for the ±5% original?

A: Yes. The ±1% tolerance parts are fully backward compatible. They provide tighter resistance tolerance, which is a performance enhancement. All upgraded alternatives maintain the same 1.6 kOhms nominal resistance, 0.05W power rating, and 0201 package form factor. No circuit redesign or board layout modification is required.

Q: What is the difference between parts with -55°C to 155°C and -55°C to 125°C operating ranges?

A: The operating temperature range defines the maximum and minimum temperatures at which the resistor maintains its specified electrical characteristics. Parts rated to 155°C provide extended high-temperature capability. If your application operates above 125°C, select parts with the 155°C upper limit. For applications within -55°C to 125°C, both ranges are acceptable.

Q: Why do some parts have different temperature coefficients (±100ppm/°C, ±200ppm/°C, ±250ppm/°C)?

A: Temperature coefficient indicates how much the resistance value changes per degree Celsius. Lower values (±100ppm/°C) indicate better stability across temperature variations. For precision applications, select parts with ±100ppm/°C. For general applications, ±200ppm/°C or ±250ppm/°C are acceptable.

Q: Are all substitute parts ROHS3 compliant and MSL 1 rated?

A: Yes. All listed substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original RK73B1HTTC162J specifications. This ensures compliance with environmental regulations and eliminates moisture-related handling restrictions.

Q: What does "Not For New Designs" status mean for the original part?

A: This designation indicates the RK73B1HTTC162J is in end-of-life phase and should not be used in new product designs. However, it remains available for existing production support. For new designs, select from Active status alternatives such as RK73B1HTTCM162J, AC0201JR-071K6L, CRCW02011K60JNED, or ERJ-1GNJ162C.

Q: Can I mix different manufacturers' parts in the same production batch?

A: Yes. All listed substitute parts meet identical electrical specifications (1.6 kΩ, ±5% or ±1%, 0.05W, 0201 package) and are ROHS3 compliant with MSL 1 rating. They are electrically and mechanically interchangeable. However, verify that your procurement and quality assurance processes accommodate multiple manufacturer sources if required.

Q: Which substitute part offers the best long-term availability?

A: ERJ-1GNJ162C (Panasonic Electronic Components) with ±5% tolerance and ERJ-1GNF1601C (Panasonic Electronic Components) with ±1% tolerance both show high inventory levels (85,161 and 98,302 pcs respectively) and Active product status, indicating strong long-term availability. CRCW02011K60FKED (Vishay Dale) also provides excellent availability (20,674 pcs) with extended temperature range and superior temperature coefficient.

Q: Is the 0201 package the same across all substitute parts?

A: Yes. All substitute parts use the 0201 package (0.60mm x 0.30mm), which is identical to the original RK73B1HTTC162J. Physical dimensions, footprint, and mounting characteristics are equivalent across all listed alternatives. No PCB redesign is necessary.
