Substitute Part Grouping Explanation

Substitution eligibility for the RR01J27RTB is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 27 Ohms
• Tolerance: ±5%
• Power rating: 1W
• Composition: Metal Film

Mechanical Compatibility Requirements:

• Package type: Axial through-hole
• Number of terminations: 2
• Physical dimensions: Compatible with standard axial footprints

Compliance Requirements:

• RoHS3 compliance
• Active product status

The substitute part PR01000102709JR500 meets all electrical and mechanical equivalence criteria. Differences in temperature coefficient and maximum operating temperature do not preclude substitution when the application operating conditions fall within the substitute part's specified range.

Engineering Selection Recommendations

RR01J27RTB (Primary Part):

• Select when maximum operating temperature above 155°C is required
• Select when tighter temperature coefficient specification (±300ppm/°C) is necessary
• Select when pulse withstanding performance is the primary design criterion
• Active product status with 5469 units in stock

PR01000102709JR500 (Substitute Part):

• Select when automotive AEC-Q200 qualification is required
• Select when fusible resistor characteristics are specified
• Select when operating temperature range of -55°C to 155°C is acceptable
• Select when superior temperature coefficient performance (±250ppm/°C) is beneficial
• Extensive inventory availability with 428852 units in stock

Both parts are ROHS3 compliant and carry active product status. Selection between the primary and substitute part depends on application-specific temperature requirements and automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can PR01000102709JR500 be used in applications requiring operation above 155°C?

A: No. The PR01000102709JR500 has a maximum operating temperature of 155°C. Applications requiring operation up to 235°C must use the RR01J27RTB.

Q: Are the physical dimensions of these parts interchangeable on a PCB?

A: The parts have similar but not identical dimensions. RR01J27RTB measures 0.102" Dia x 0.268" L, while PR01000102709JR500 measures 0.098" Dia x 0.256" L. Both are standard axial packages and fit within typical axial component footprints. Verify PCB layout clearances for the specific application.

Q: What is the difference in temperature coefficient between these parts?

A: RR01J27RTB has a temperature coefficient of ±300ppm/°C, while PR01000102709JR500 has ±250ppm/°C. The substitute part exhibits better temperature stability. This difference is significant only in precision applications with strict tolerance requirements across temperature ranges.

Q: Does the substitute part meet automotive standards?

A: Yes. PR01000102709JR500 carries AEC-Q200 automotive qualification. RR01J27RTB does not specify automotive qualification. Select PR01000102709JR500 for automotive applications requiring AEC-Q200 compliance.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RR01J27RTB and PR01000102709JR500 are ROHS3 compliant and REACH unaffected.

Q: What does "fusible" mean in the context of the substitute part?

A: The PR01000102709JR500 is specified as a fusible resistor, meaning it is designed to open circuit under excessive current conditions. This feature provides additional circuit protection. The RR01J27RTB does not carry this specification.

Q: Which part should be selected for new designs?

A: For new designs, evaluate application requirements for maximum operating temperature and automotive qualification. If operation above 155°C is not required and automotive AEC-Q200 qualification is beneficial, PR01000102709JR500 is the preferred choice due to superior temperature coefficient and extensive inventory. If maximum temperature capability or pulse withstanding performance is critical, select RR01J27RTB.
