Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RK73B1ETTP162J are classified based on electrical and mechanical compatibility within the following criteria:

Direct Equivalents (Upgrade Category): Parts that maintain identical resistance value (1.6 kOhms), identical package format (0402), identical operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. These parts differ in tolerance specification, power rating, temperature coefficient, or packaging format (Tape & Reel vs. Cut Tape).

Similar Parts (Comparable Category): Parts that share the same package format (0402), similar operating temperature range, and thick film composition but differ in resistance value or automotive qualification status.

The following parameters determine substitution eligibility:

• Resistance value tolerance to ±5% or better
• Package format 0402 (1005 Metric)
• Operating temperature range minimum -55°C and maximum 155°C
• Thick film composition
• RoHS3 compliance

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Electrically Equivalent):

ERJ-2GEJ162X and ERJ-2RKF1601X from Panasonic, along with RMCF0402JT1K60 and RMCF0402FT1K60 from Stackpole, are direct electrical equivalents to RK73B1ETTP162J. All maintain 1.6 kOhms resistance, 0402 package format, -55°C to 155°C operating range, and AEC-Q200 automotive qualification. Selection between these parts depends on tolerance requirements (±5% or ±1%), power rating adequacy (0.1W or 0.063W), and packaging format availability (Tape & Reel or Cut Tape).

Tolerance Upgrade Path:

ERJ-2RKF1601X and RMCF0402FT1K60 offer ±1% tolerance with improved temperature coefficient (±100ppm/°C) compared to the ±200ppm/°C of the main part. These are suitable for applications requiring tighter resistance tolerance and improved thermal stability.

Power Rating Consideration:

RMCF0402JT1K60 and RMCF0402FT1K60 feature reduced power rating (0.063W vs. 0.1W). These parts are suitable only where circuit power dissipation does not exceed 0.063W per resistor.

Similar Alternative (Resistance Variance):

RC0402JR-071K5L from YAGEO provides 1.5 kOhms resistance (within ±5% tolerance band of 1.6 kOhms nominal) in 0402 package. This part lacks AEC-Q200 automotive qualification and is classified as a similar alternative for non-automotive applications only.

All substitute parts maintain RoHS3 compliance, MSL 1 rating, and identical physical dimensions (0.039" L x 0.020" W, 0.016" max height).

Frequently Asked Questions (FAQ)

Q: Can ERJ-2GEJ162X replace RK73B1ETTP162J directly?

A: Yes. ERJ-2GEJ162X is electrically and mechanically equivalent with identical resistance (1.6 kOhms), tolerance (±5%), power rating (0.1W), operating temperature range (-55°C to 155°C), and AEC-Q200 qualification. The only difference is packaging format (Cut Tape & Digi-Reel® vs. Tape & Reel). Verify packaging compatibility with assembly equipment before substitution.

Q: What is the difference between ERJ-2RKF1601X and RK73B1ETTP162J?

A: ERJ-2RKF1601X offers improved tolerance (±1% vs. ±5%) and lower temperature coefficient (±100ppm/°C vs. ±200ppm/°C). Power rating and operating temperature range remain identical. This part is suitable for applications requiring tighter resistance tolerance and better thermal stability.

Q: Can RMCF0402JT1K60 be used in place of RK73B1ETTP162J?

A: RMCF0402JT1K60 is electrically equivalent in resistance and tolerance but features reduced power rating (0.063W vs. 0.1W). Substitution is valid only if circuit power dissipation per resistor does not exceed 0.063W. Verify thermal requirements before use.

Q: Is RC0402JR-071K5L a suitable substitute?

A: RC0402JR-071K5L differs in resistance value (1.5 kOhms vs. 1.6 kOhms) and lacks AEC-Q200 automotive qualification. This part is not suitable for automotive applications. Use only in non-automotive circuits where 1.5 kOhms resistance is acceptable.

Q: What packaging formats are available for equivalent parts?

A: Equivalent parts are available in Tape & Reel (TR) format (ERJ-2RKF1601X, RMCF0402JT1K60, RMCF0402FT1K60) and Cut Tape & Digi-Reel® format (ERJ-2GEJ162X). Verify assembly equipment compatibility with selected packaging format.

Q: Do all substitute parts meet automotive standards?

A: All substitute parts except RC0402JR-071K5L carry AEC-Q200 automotive qualification. RC0402JR-071K5L is rated for moisture resistance only and is not automotive-qualified.

Q: What is the impact of temperature coefficient differences?

A: RK73B1ETTP162J has ±200ppm/°C temperature coefficient. Substitute parts ERJ-2RKF1601X and RMCF series have ±100ppm/°C. Lower temperature coefficient indicates better resistance stability across temperature variations, beneficial for precision circuits operating across wide temperature ranges.
