Substitute Part Grouping Explanation

Substitute parts for the RC5025J302CS are qualified based on the following substitution criteria:

Mandatory Compatibility Parameters:

• Resistance value: 3 kOhms (exact match required)
• Package type: 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: Yes (exact match required)
• RoHS3 Compliance: Compliant (exact match required)
• MSL Rating: Level 1 (exact match required)

Allowable Variation Parameters:

• Tolerance: May upgrade from ±5% to ±1% (tighter tolerance is backward compatible)
• Power Rating: May upgrade from 0.667W to 0.75W (higher power rating is backward compatible)
• Manufacturer: Alternative qualified manufacturers permitted
• Packaging Format: Tape & Reel acceptable as alternative to standard packaging

The two identified substitutes (RC2010FK-073KL and RC2010JK-073KL) maintain all mandatory parameters while offering enhanced specifications in tolerance and/or power rating.

Parameter Comparison

Engineering Selection Recommendations

RC2010FK-073KL (YAGEO) is selected as a substitute when circuit design permits tolerance improvement to ±1% while requiring increased power dissipation capacity of 0.75W. This part offers enhanced accuracy specification and thermal margin compared to the original RC5025J302CS. Both components maintain identical operating temperature range, moisture resistance, and regulatory compliance status.

RC2010JK-073KL (YAGEO) is selected as a substitute when power rating upgrade to 0.75W is required while maintaining the original ±5% tolerance specification. This part provides thermal headroom for applications with higher power dissipation requirements while preserving the original tolerance class. Both components maintain identical operating temperature range, moisture resistance, and regulatory compliance status.

Both substitute parts are Active status components with full RoHS3 compliance and MSL Level 1 rating, ensuring regulatory and environmental compatibility with the original RC5025J302CS specification.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-073KL or RC2010JK-073KL be used as direct replacements for RC5025J302CS?

A: Yes, both parts are direct substitutes within the 2010 (5025 Metric) package footprint. All mandatory electrical and mechanical parameters are identical. RC2010FK-073KL offers improved tolerance (±1% vs ±5%), and both substitutes provide increased power rating (0.75W vs 0.667W).

Q: What is the primary difference between the two substitute options?

A: RC2010FK-073KL provides ±1% tolerance with 0.75W power rating. RC2010JK-073KL maintains ±5% tolerance with 0.75W power rating. Selection depends on circuit accuracy requirements.

Q: Are there physical compatibility concerns when substituting these parts?

A: No. All three parts share identical 2010 (5025 Metric) package dimensions (5.00mm L x 2.50mm W) with maximum seated heights of 0.65-0.66mm. PCB footprints and assembly processes remain unchanged.

Q: Do the substitute parts meet the same environmental and regulatory standards?

A: Yes. Both RC2010FK-073KL and RC2010JK-073KL are RoHS3 compliant, REACH unaffected, and rated MSL Level 1 (Unlimited). Operating temperature range is -55°C ~ 155°C for all three parts.

Q: What is the temperature coefficient specification for substitute parts?

A: Both substitute parts maintain ±100ppm/°C temperature coefficient, identical to the original RC5025J302CS.

Q: Are substitute parts available in the same packaging format?

A: RC2010FK-073KL and RC2010JK-073KL are supplied in Tape & Reel (TR) format. Original RC5025J302CS packaging format is not specified in the provided data. Verify packaging requirements for assembly compatibility.

Q: Can the higher power rating of substitute parts cause circuit performance issues?

A: No. Higher power rating (0.75W vs 0.667W) provides additional thermal margin and does not alter electrical performance. The component will operate within the same voltage and current parameters as the original part.
