Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/16SK5233FTH is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 523 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package format: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Number of terminations: 2
• Moisture sensitivity level: 1 (Unlimited)

The ERJ-2RKF5233X from Panasonic Electronic Components meets all critical matching parameters and qualifies as a direct substitute. Additional certifications such as AEC-Q200 automotive qualification present in the substitute part do not prevent substitution; they represent enhanced qualification levels.

Parameter Comparison

Engineering Selection Recommendations

Both the RMC1/16SK5233FTH and ERJ-2RKF5233X are active production components with identical electrical and mechanical specifications. Selection between these parts may be based on the following factors:

Inventory Availability: The ERJ-2RKF5233X (Panasonic) has significantly higher stock availability at 50,633 pieces compared to 1,072 pieces for the RMC1/16SK5233FTH (Kamaya Inc.).

Compliance and Certifications: The ERJ-2RKF5233X carries AEC-Q200 automotive qualification and ROHS3 compliance. These certifications do not alter the component's core electrical function but indicate qualification for automotive and regulated applications.

Supply Chain Considerations: Both components are REACH Unaffected and classified under ECCN EAR99, presenting no regulatory barriers to substitution.

Regulatory Status: Both parts maintain identical HTSUS classification (8533.21.0030), confirming tariff and trade compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-2RKF5233X replace the RMC1/16SK5233FTH in all applications?

A: Yes. The ERJ-2RKF5233X meets all critical electrical and mechanical parameters of the RMC1/16SK5233FTH. Both components share identical resistance value (523 kOhms), tolerance (±1%), power rating (0.1W), package format (0402), and operating temperature range (-55°C to 155°C). No circuit redesign is required.

Q: What is the significance of the AEC-Q200 rating on the ERJ-2RKF5233X?

A: AEC-Q200 is an automotive qualification standard. This certification indicates the ERJ-2RKF5233X has undergone additional reliability testing for automotive applications. The presence of this certification does not prevent use in non-automotive applications and does not alter the component's electrical performance.

Q: Are there any package or footprint differences between these parts?

A: No. Both components use the 0402 (1005 Metric) package with identical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). PCB footprints are identical.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both the RMC1/16SK5233FTH and ERJ-2RKF5233X are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any regulatory or compliance differences?

A: No significant differences exist. Both components are REACH Unaffected, classified as EAR99, and share the same HTSUS code (8533.21.0030). The ERJ-2RKF5233X includes ROHS3 compliance, which represents an additional certification level without affecting substitution eligibility.

Q: What is the temperature coefficient specification and why does it matter?

A: Both parts have a temperature coefficient of ±100ppm/°C. This specification defines the maximum change in resistance value per degree Celsius across the operating temperature range. Identical coefficients ensure equivalent performance stability across temperature variations.

Q: Can these parts be used interchangeably in tape and reel packaging?

A: Yes. Both components are supplied in Tape & Reel (TR) packaging format, enabling direct substitution in automated assembly processes without packaging format conversion.
