RT0603P-271-M Equivalent & Substitute Parts

Part Overview

The RT0603P-271-M is a 270 Ohms ±20% thin film chip resistor manufactured by Susumu in the 0201 (0603 Metric) package format. This surface mount device is rated for 0.05W (1/20W) power dissipation and operates across the temperature range of -55°C to 125°C. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent resistance values, power ratings, and package specifications are maintained while offering improved tolerance or alternative availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0603P-271-M is determined by strict adherence to the following parameters:

Mandatory Matching Parameters:

• Resistance value of 270 Ohms
• Package format 0201 (0603 Metric)
• Power rating of 0.05W (1/20W) minimum
• Thin film composition
• Operating temperature range of -55°C to 125°C or wider
• RoHS3 compliance status
• MSL rating of 1 or better

Allowable Variations:

• Tolerance may be tighter (lower percentage) than the original ±20%
• Temperature coefficient remains constant at ±25ppm/°C across all qualified substitutes
• Physical dimensions may vary within supplier specifications for the same package class
• Inventory availability and series designation do not affect substitution eligibility

The RR0306P-271-D qualifies as a direct substitute based on matching all mandatory parameters while providing improved tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

RT0603P-271-M Selection Criteria: The RT0603P-271-M is appropriate for applications where ±20% tolerance is acceptable and cost optimization is prioritized. This part maintains Active product status with established supply availability (949 Pcs in stock). Full compliance with RoHS3 and REACH requirements qualifies this component for regulated markets.

RR0306P-271-D Selection Criteria: The RR0306P-271-D provides superior tolerance performance at ±0.5%, suitable for precision circuit applications requiring tighter resistance accuracy. This substitute maintains identical power rating, package format, and temperature operating range. The RR0306P-271-D demonstrates higher inventory availability (5695 Pcs in stock) and marginally reduced seated height (0.010" versus 0.011"), which may benefit high-density PCB layouts. Both parts carry equivalent regulatory compliance certifications.

Substitution Feasibility: Direct substitution of RR0306P-271-D for RT0603P-271-M is permissible in all applications where the original specification is met. The tighter tolerance of the substitute part does not create incompatibility with circuits designed for the original ±20% tolerance specification.

Frequently Asked Questions (FAQ)

Q: Can RR0306P-271-D replace RT0603P-271-M in existing designs?

A: Yes. The RR0306P-271-D meets or exceeds all critical parameters of the RT0603P-271-M, including resistance value, power rating, package format, operating temperature range, and regulatory compliance. The improved tolerance specification of ±0.5% is compatible with applications designed for ±20% tolerance.

Q: Are there physical compatibility concerns between these parts?

A: Both parts use the 0201 (0603 Metric) package with identical length and width dimensions (0.024" x 0.012"). The RR0306P-271-D has a maximum seated height of 0.010" compared to 0.011" for the RT0603P-271-M. This 0.001" difference is within standard PCB assembly tolerances and does not affect placement or soldering processes.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both the RT0603P-271-M and RR0306P-271-D carry MSL 1 (Unlimited) ratings, indicating identical moisture sensitivity handling requirements. No additional precautions are necessary when transitioning between these parts.

Q: What is the significance of the tolerance difference?

A: The RT0603P-271-M specifies ±20% tolerance, while the RR0306P-271-D specifies ±0.5% tolerance. For a 270 Ohm resistor, this means the RT0603P-271-M can range from 216 to 324 Ohms, while the RR0306P-271-D ranges from 268.65 to 271.35 Ohms. Applications requiring precise resistance values benefit from the tighter tolerance of the substitute part.

Q: Are regulatory certifications equivalent between these parts?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8533.21.0030. No additional compliance documentation is required when substituting between these components.

Q: Does the temperature coefficient differ between these parts?

A: No. Both the RT0603P-271-M and RR0306P-271-D maintain a temperature coefficient of ±25ppm/°C and operate across the identical temperature range of -55°C to 125°C.
