RC0603J393CS

Part Overview

The RC0603J393CS is a 39 kOhms ±5% chip resistor in 0201 (0603 Metric) package manufactured by Samsung Electro-Mechanics. This thick film, moisture-resistant component is rated for 0.05W (1/20W) power dissipation and operates across -55°C to 125°C. The part is currently active in production with 1152 units in stock. Substitutes may be required due to supply constraints, manufacturing discontinuation of alternative models, or procurement optimization across multiple suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the RC0603J393CS is determined by strict equivalence in the following electrical and mechanical parameters: 39 kOhms resistance value, ±5% tolerance, 0.05W power rating, 0201 package, thick film composition, ±250ppm/°C temperature coefficient, and -55°C to 125°C operating range. All substitute parts must maintain identical RoHS3 compliance and MSL 1 rating. The MCR006YRTJ393 manufactured by Rohm Semiconductor meets all these requirements and qualifies as a direct electrical and mechanical equivalent despite its discontinued status at DiGi Electronics.

Parameter Comparison

Engineering Selection Recommendations

Both the RC0603J393CS and MCR006YRTJ393 are ROHS3 compliant with REACH unaffected status and identical MSL 1 ratings, confirming their suitability for equivalent board-level substitution. The primary difference is product status: the RC0603J393CS remains active with current production availability, while the MCR006YRTJ393 is discontinued at DiGi Electronics. Selection between these parts should prioritize the active Samsung Electro-Mechanics part for new designs and long-term supply security. The Rohm part may serve as a secondary option for inventory management or design revision purposes where existing stocks are available.

Frequently Asked Questions (FAQ)

Q: Can MCR006YRTJ393 replace RC0603J393CS in existing designs? A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters: 39 kOhms ±5%, 0.05W power rating, 0201 package, ±250ppm/°C temperature coefficient, and -55°C to 125°C operating range. RoHS3 and MSL 1 compliance are identical.

Q: What parameters determine substitutability for this resistor? A: Substitutes must match the resistance value (39 kOhms), tolerance (±5%), power rating (0.05W), package (0201), composition (thick film), temperature coefficient (±250ppm/°C), operating range (-55°C to 125°C), RoHS status, and moisture sensitivity level.

Q: Why is the Rohm MCR006YRTJ393 discontinued? A: The MCR006YRTJ393 is discontinued at DiGi Electronics as indicated by its product status. This does not affect its electrical or mechanical equivalence but may limit future availability.

Q: Are there any thermal or environmental differences between these parts? A: No. Both parts share identical operating temperature range (-55°C to 125°C), temperature coefficient (±250ppm/°C), and moisture sensitivity level (MSL 1, Unlimited exposure tolerance).

Q: What does ROHS3 compliance mean for component selection? A: ROHS3 compliance certifies that both parts meet Restriction of Hazardous Substances regulations, confirming lead-free construction and suitability for regulated industries and modern manufacturing environments.
