Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Parameters (Must Match):

• Resistance value: 2.05 kOhms
• Package: 0402 (1005 Metric)
• Composition: Thin Film
• Power rating: 0.063W (1/16W)
• Termination count: 2

Allowable Variation Parameters:

• Tolerance: ±1% (original) to ±0.1% (tighter tolerance acceptable as upgrade)
• Temperature coefficient: ±50ppm/°C to ±25ppm/°C (lower coefficient acceptable)
• Operating temperature range: -55°C to 155°C (original) or -55°C to 125°C (acceptable for most applications)
• Manufacturer: YAGEO, TE Connectivity, Panasonic, Susumu
• Height variation: 0.014" to 0.016" (within PCB assembly tolerance)

All substitute parts maintain ROHS3 compliance and MSL 1 rating. The ERA-2AEB2051X includes AEC-Q200 automotive qualification as an additional feature.

Parameter Comparison

Engineering Selection Recommendations

YAGEO RT0402BRD072K05L and RT0402BRE072K05L: Both are direct YAGEO upgrades offering ±0.1% tolerance versus the original ±1%. RT0402BRD072K05L provides superior temperature stability (±25ppm/°C). RT0402BRE072K05L maintains the original ±50ppm/°C coefficient. Both are ROHS3 compliant with 10,537 units available (RT0402BRE072K05L), ensuring supply continuity.

TE Connectivity CPF0402B2K05E1: Neohm series thin film resistor with ±0.1% tolerance and ±25ppm/°C temperature coefficient. ROHS3 compliant. Suitable for applications requiring cross-manufacturer sourcing flexibility. 1,003 units in stock.

Panasonic ERA-2AEB2051X: Automotive-grade AEC-Q200 qualified resistor with ±0.1% tolerance and ±25ppm/°C coefficient. Height is 0.016" (0.40mm maximum seated height). Recommended for automotive and high-reliability applications. 10,865 units available.

Susumu RR0510P-2051-D: Offers ±0.5% tolerance with ±25ppm/°C temperature coefficient. Operating temperature range is -55°C to 125°C (5°C lower maximum than original). Height is 0.016". Suitable for general-purpose applications where tighter tolerance is not required. 10,809 units in stock.

All substitute parts maintain the same 0402 package footprint, 2-termination configuration, and ROHS3/MSL 1 compliance as the original RT0402FRE072K05L.

Frequently Asked Questions (FAQ)

Q: Can I substitute RT0402FRE072K05L with a part having ±0.1% tolerance? A: Yes. Tighter tolerance (±0.1%) is a direct upgrade and maintains full electrical compatibility. Parts RT0402BRD072K05L, RT0402BRE072K05L, CPF0402B2K05E1, and ERA-2AEB2051X all provide this upgrade.

Q: What is the difference between RT0402BRD072K05L and RT0402BRE072K05L? A: Both are YAGEO ±0.1% tolerance upgrades. RT0402BRD072K05L has ±25ppm/°C temperature coefficient (superior stability). RT0402BRE072K05L maintains ±50ppm/°C. Select based on thermal stability requirements.

Q: Is ERA-2AEB2051X suitable for automotive applications? A: Yes. ERA-2AEB2051X carries AEC-Q200 automotive qualification and is recommended for automotive and high-reliability designs. All other substitutes are industrial-grade.

Q: Can I use RR0510P-2051-D as a direct replacement? A: Yes, with one consideration: maximum operating temperature is 125°C versus 155°C for the original. Verify your application does not exceed 125°C ambient or component temperature.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental compliance.

Q: Does package height variation affect PCB assembly? A: ERA-2AEB2051X and RR0510P-2051-D have 0.016" maximum seated height versus 0.014" for the original and other YAGEO/TE parts. This 0.002" difference is within standard PCB assembly tolerances and does not affect reflow or placement.

Q: Which substitute offers the best temperature stability? A: RT0402BRD072K05L, CPF0402B2K05E1, and ERA-2AEB2051X all provide ±25ppm/°C temperature coefficient, superior to the original ±50ppm/°C.
