Substitute Part Grouping Explanation

Substitute parts for the RC5025J392CS are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following parameters:

Critical Matching Parameters:

• Resistance value: 3.9 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Package format: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Moisture resistance: Required feature
• RoHS3 compliance: Required
• MSL rating: 1 (Unlimited) or equivalent

Allowable Variation:

• Power rating: Substitute parts may have equal or higher power ratings while maintaining identical physical dimensions and electrical characteristics

The RC2010JK-073K9L from YAGEO qualifies as a substitute due to matching all critical parameters while providing an increased power rating of 0.75W (3/4W) compared to the original 0.667W specification.

Parameter Comparison

Engineering Selection Recommendations

The RC2010JK-073K9L from YAGEO is a direct substitute for the RC5025J392CS from Samsung Electro-Mechanics. Both components maintain identical electrical specifications, physical dimensions, and compliance certifications. The substitute part provides an increased power dissipation capability (0.75W versus 0.667W) while preserving all other critical parameters.

Selection between these parts is based on:

Availability and Supply Chain: The YAGEO RC2010JK-073K9L offers higher inventory availability (3147 units in stock) compared to the Samsung part (652 units in stock).

Compliance Status: Both parts are ROHS3 compliant, REACH unaffected, and carry identical environmental ratings (MSL 1 - Unlimited).

Physical Compatibility: Identical package dimensions and height specifications ensure direct board-level compatibility without layout modifications.

Electrical Performance: The substitute part's higher power rating provides additional thermal margin in applications operating near the original part's power dissipation limits, while maintaining identical resistance, tolerance, and temperature coefficient specifications.

Frequently Asked Questions (FAQ)

Q: Can the RC2010JK-073K9L replace the RC5025J392CS in existing designs?

A: Yes. The RC2010JK-073K9L is electrically and mechanically compatible with the RC5025J392CS. Both components share identical resistance values (3.9 kOhms), tolerance (±5%), package format (2010/5025 Metric), physical dimensions, and operating temperature ranges (-55°C ~ 155°C). The substitute part's increased power rating (0.75W versus 0.667W) does not create compatibility issues.

Q: What is the significance of the higher power rating on the substitute part?

A: The RC2010JK-073K9L is rated for 0.75W continuous power dissipation compared to the original part's 0.667W rating. This higher rating provides additional thermal headroom in applications where the resistor operates near its maximum power specification. The increased rating does not affect electrical performance or introduce incompatibility.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the RC5025J392CS and RC2010JK-073K9L are packaged in the 2010 (5025 Metric) format with identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm) dimensions. Maximum seated heights are equivalent (0.66mm and 0.65mm respectively), ensuring direct board-level substitution without layout modifications.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Environmental and regulatory compliance is maintained across both parts.

Q: What is the tolerance specification for these resistors?

A: Both the RC5025J392CS and RC2010JK-073K9L carry a ±5% tolerance specification on the 3.9 kOhms resistance value. This tolerance is identical across both parts.

Q: Are there any packaging differences between these parts?

A: The RC5025J392CS is supplied in standard packaging, while the RC2010JK-073K9L is supplied in Tape & Reel (TR) format. Both packaging formats are suitable for automated assembly processes. The component specifications and performance characteristics remain identical regardless of packaging format.

Q: What is the temperature coefficient specification?

A: Both parts specify a temperature coefficient of ±100ppm/°C across the operating temperature range of -55°C to 155°C. This specification is identical for both the Samsung and YAGEO components.
