RC0402J332CS Equivalent & Substitute Parts

Part Overview

The RC0402J332CS is a 3.3 kOhms ±5% chip resistor manufactured by Samsung Electro-Mechanics, designed for applications requiring compact 01005 (0402 Metric) form factor components. This thick film resistor operates across -55°C to 125°C with moisture resistant characteristics and 1/32W power rating. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within specified tolerance and environmental parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC0402J332CS are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Resistance value must equal 3.3 kOhms
• Package must be 01005 (0402 Metric) with identical physical dimensions (0.40mm L × 0.20mm W, 0.15mm max height)
• Power rating must be minimum 0.03W (1/32W)
• Composition must be thick film
• Temperature coefficient must be ±250ppm/°C
• Operating temperature range must encompass -55°C to 125°C
• RoHS3 compliance required
• MSL rating must be 1 (Unlimited)

Tolerance Consideration: Substitute parts with tolerance equal to or tighter than ±5% are acceptable. A substitute with ±1% tolerance meets this criterion as it provides equal or superior accuracy.

Parameter Comparison

Engineering Selection Recommendations

RC0402J332CS (Samsung Electro-Mechanics)

Primary selection when ±5% tolerance specification is acceptable. Active production status with 933 units in stock. ROHS3 compliant with unlimited moisture sensitivity level. Moisture resistant thick film composition suitable for standard industrial applications.

CRCW01003K30FREL (Vishay Dale)

Direct substitute with superior tolerance specification (±1% versus ±5%). Identical electrical and mechanical parameters across all critical dimensions. Active production status with 20,867 units in stock. ROHS3 compliant with unlimited moisture sensitivity level. Selection recommended when tighter tolerance requirements exist or when Samsung supply is constrained. Interchangeable at PCB assembly level with identical footprint and termination configuration.

Both parts satisfy identical regulatory compliance requirements (ROHS3, REACH Unaffected, EAR99 classification) and environmental operating specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW01003K30FREL replace RC0402J332CS in existing designs?

A: Yes. Both parts share identical 01005 (0402 Metric) package dimensions, footprint, and electrical specifications for resistance value and power rating. The substitute part features tighter tolerance (±1% versus ±5%), which is compatible with applications designed for the original part.

Q: What is the significance of the tolerance difference between ±5% and ±1%?

A: Tolerance defines the acceptable resistance variance from the nominal 3.3 kOhms value. The RC0402J332CS allows variance between 3.135 kOhms and 3.465 kOhms. The CRCW01003K30FREL allows variance between 3.267 kOhms and 3.333 kOhms. The substitute provides superior accuracy and is suitable for applications requiring tighter resistance control.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 01005 (0402 Metric) package with 0.40mm length, 0.20mm width, and 0.15mm maximum seated height. PCB footprints are identical.

Q: Do both parts meet the same environmental specifications?

A: Yes. Both operate across -55°C to 125°C with ±250ppm/°C temperature coefficient. Both maintain MSL 1 (Unlimited) moisture sensitivity level and ROHS3 compliance.

Q: Which part should be selected for new designs?

A: Selection depends on tolerance requirements. For applications where ±5% tolerance is sufficient, either part is acceptable. For applications requiring tighter tolerance control, CRCW01003K30FREL is the appropriate selection. Both parts are in active production with adequate supply availability.

Q: Are there any performance differences in thick film composition?

A: Both parts use thick film composition with identical temperature coefficient (±250ppm/°C) and operating temperature range. No performance differentiation exists in this parameter category.
