RT0603P-331-M Equivalent & Substitute Parts

Part Overview

The RT0603P-331-M is a 330 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 MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent resistance values, power ratings, and package specifications are maintained while offering improved electrical characteristics such as tighter tolerance specifications or enhanced reliability features.

Substitute Part Grouping Explanation

Substitution of the RT0603P-331-M is determined by strict equivalence in the following parameters:

• Resistance Value: 330 Ohms (exact match required)
• Power Rating: 0.05W / 1/20W (exact match required)
• Package Format: 0201 (0603 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Compliance Standards: RoHS3 Compliant, MSL 1, REACH Unaffected (exact match required)

The substitute part RR0306P-331-D meets all mandatory equivalence criteria. The primary distinction is tolerance specification: the substitute offers ±0.5% tolerance compared to the main part's ±20% tolerance. This represents an upgrade in precision without altering functional compatibility or package specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0603P-331-M and RR0306P-331-D are Active status products manufactured by Susumu with full RoHS3 compliance and REACH unaffected status. Both parts are suitable for applications requiring 330 Ohm thin film resistors in the 0201 package format.

The RT0603P-331-M is appropriate for applications where ±20% tolerance specifications are acceptable and cost optimization is a priority.

The RR0306P-331-D is appropriate for applications requiring tighter tolerance control at ±0.5%, providing enhanced precision in circuit performance. The substitute part exhibits a marginally lower seated height (0.010" versus 0.011"), which may provide advantages in space-constrained PCB layouts.

Both parts maintain identical thermal characteristics, temperature operating range, and regulatory compliance profiles. Selection between these parts is determined by tolerance requirements specific to the application circuit design.

Frequently Asked Questions (FAQ)

Q: Can RR0306P-331-D be used as a direct replacement for RT0603P-331-M?

A: Yes. Both parts share identical resistance values (330 Ohms), power ratings (0.05W), package specifications (0201 / 0603 Metric), composition (thin film), temperature coefficients (±25ppm/°C), and operating temperature ranges (-55°C ~ 125°C). The substitute part is physically and electrically compatible with the main part in all standard PCB assembly processes.

Q: What is the primary difference between these two parts?

A: The primary difference is tolerance specification. The RT0603P-331-M offers ±20% tolerance, while the RR0306P-331-D offers ±0.5% tolerance. This means the substitute part maintains resistance values within a significantly tighter range, providing improved precision for applications requiring strict resistance accuracy.

Q: Are there any package or footprint differences?

A: Both parts use the 0201 (0603 Metric) package with identical lateral dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm). The RR0306P-331-D has a slightly lower maximum seated height of 0.010" compared to 0.011" for the RT0603P-331-M. This minimal difference does not affect standard PCB assembly or component placement.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the RT0603P-331-M and RR0306P-331-D are RoHS3 compliant, REACH unaffected, classified as EAR99, and carry the same HTSUS code (8533.21.0030). Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for precision-critical applications?

A: The RR0306P-331-D with ±0.5% tolerance is appropriate for applications requiring precise resistance values. The RT0603P-331-M with ±20% tolerance is appropriate for general-purpose applications where tolerance requirements are less stringent.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging format suitable for automated assembly processes.
