RT0603R-152-M Equivalent & Substitute Parts

Part Overview

The RT0603R-152-M is a 1.5 kOhms ±20% thin film chip resistor manufactured by Susumi in 0201 (0603 Metric) package format. This surface mount device (SMD) is rated for 0.05W (1/20W) power dissipation and operates across the temperature range of -55°C to 125°C. The part is Active in product status and carries ROHS3 compliance with unlimited moisture sensitivity level (MSL 1).

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

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0603R-152-M is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1.5 kOhms
• Power rating: 0.05W (1/20W)
• Package format: 0201 (0603 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 125°C
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

Allowable Variation Parameters:

• Tolerance: May be tighter (lower value) than ±20%
• Temperature coefficient: May be lower (improved stability)
• Physical height: May be lower than maximum seated height

The substitute part RR0306P-152-D meets all mandatory matching parameters while providing improved tolerance (±0.5% versus ±20%) and superior temperature coefficient (±25ppm/°C versus ±100ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

RT0603R-152-M Selection Criteria: The RT0603R-152-M is appropriate for applications where ±20% tolerance is acceptable and cost optimization is prioritized. This part maintains Active product status and full ROHS3 compliance with unlimited moisture sensitivity rating.

RR0306P-152-D Selection Criteria: The RR0306P-152-D is appropriate for applications requiring tighter tolerance control (±0.5%) and improved temperature stability (±25ppm/°C). This substitute maintains identical package compatibility, power rating, and operating temperature range while providing enhanced precision characteristics. The substitute also features a lower seated height (0.010" versus 0.011"), which may provide advantages in space-constrained PCB layouts. Both parts carry identical regulatory compliance (ROHS3, REACH Unaffected, EAR99).

Both parts are manufactured by Susumu and carry Active product status, ensuring continued availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can RR0306P-152-D be used as a direct replacement for RT0603R-152-M?

A: Yes. Both parts share identical resistance value (1.5 kOhms), power rating (0.05W), package format (0201/0603 Metric), composition (Thin Film), operating temperature range (-55°C ~ 125°C), and regulatory compliance (ROHS3, MSL 1). The substitute offers improved tolerance and temperature coefficient performance.

Q: What are the key differences between these parts?

A: The primary differences are tolerance specification (±20% versus ±0.5%) and temperature coefficient (±100ppm/°C versus ±25ppm/°C). The substitute also features a slightly lower maximum seated height (0.010" versus 0.011"). All other electrical and mechanical parameters are identical.

Q: Are there any PCB layout considerations when substituting RR0306P-152-D for RT0603R-152-M?

A: No. Both parts maintain identical footprint dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and identical termination count (2). The lower seated height of the substitute may provide marginal clearance benefits in high-density layouts but does not create incompatibility.

Q: Do both parts require identical handling and storage procedures?

A: Yes. Both parts carry identical Moisture Sensitivity Level (MSL 1 - Unlimited), indicating no special moisture control requirements during storage or handling.

Q: What is the basis for substitution eligibility?

A: Substitution is based on matching resistance value, power rating, package format, composition type, operating temperature range, and regulatory compliance. Tighter tolerance and improved temperature coefficient are allowable enhancements that do not compromise compatibility.

Q: Are there supply or availability differences between these parts?

A: Inventory levels differ. RT0603R-152-M has 801 pieces in stock, while RR0306P-152-D has 3964 pieces in stock. Both parts carry Active product status.
