Substitute Part Grouping Explanation

Substitute parts for the RK73B2ATTD910J are qualified based on the following criteria:

• Identical resistance value: 91 Ohms
• Identical tolerance: ±5%
• Identical package: 0805 (2012 Metric)
• Identical composition: Thick Film
• Identical temperature coefficient: ±200ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical automotive qualification: AEC-Q200
• Identical RoHS compliance: ROHS3
• Identical moisture sensitivity: MSL 1 (Unlimited)

The substitute parts identified (CRCW080591R0JNEA and ERJ-6GEYJ910V) meet all these core parameters. A secondary consideration is power rating: while the main part is rated 0.25W, the substitutes are rated 0.125W. Lower power-rated components are acceptable substitutes in applications where the actual power dissipation does not exceed the substitute's rating.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full AEC-Q200 automotive qualification with ROHS3 compliance. Selection between the main part RK73B2ATTD910J and its substitutes CRCW080591R0JNEA or ERJ-6GEYJ910V depends on application power dissipation requirements and physical height constraints.

The RK73B2ATTD910J provides 0.25W power rating and 0.024" maximum seated height. CRCW080591R0JNEA offers the lowest profile at 0.020" maximum seated height with 0.125W rating. ERJ-6GEYJ910V provides 0.125W rating with 0.028" maximum seated height. All parts share identical electrical specifications, package footprint, and environmental ratings.

Frequently Asked Questions (FAQ)

Q: Can CRCW080591R0JNEA or ERJ-6GEYJ910V replace RK73B2ATTD910J in any application?

A: Substitution is valid only when actual circuit power dissipation does not exceed 0.125W. Both substitute parts are rated for 0.125W versus the main part's 0.25W rating. If the application requires the full 0.25W capability, the main part must be used.

Q: Are there physical compatibility concerns between these parts?

A: All three parts use identical 0805 (2012 Metric) package footprints and are mechanically compatible on PCBs. Seated heights differ slightly: RK73B2ATTD910J at 0.024", CRCW080591R0JNEA at 0.020", and ERJ-6GEYJ910V at 0.028". These variations are within standard PCB assembly tolerances and do not affect functionality.

Q: Do all parts meet automotive requirements?

A: Yes. RK73B2ATTD910J, CRCW080591R0JNEA, and ERJ-6GEYJ910V are all AEC-Q200 qualified for automotive applications with identical operating temperature ranges of -55°C to 155°C.

Q: What is the significance of the ±200ppm/°C temperature coefficient?

A: This parameter defines resistance change over temperature. All three parts share identical ±200ppm/°C specifications, ensuring equivalent thermal stability across the -55°C to 155°C operating range.

Q: Are moisture sensitivity considerations the same across all parts?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
