Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025J683CS is determined by strict adherence to the following parameters:

Critical Parameters (Must Match):

• Resistance value: 68 kOhms
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±5% (main part) to ±1% (substitute) — tighter tolerance is acceptable
• Power Rating: 0.667W (main part) to 0.75W (substitute) — higher power rating is acceptable

Both identified substitute parts (RC2010FK-0768KL and RC2010JK-0768KL) maintain all critical parameters while offering enhanced specifications in tolerance and/or power rating. These substitutes are electrically and mechanically compatible with the original RC5025J683CS.

Parameter Comparison

Engineering Selection Recommendations

RC2010FK-0768KL (YAGEO) — Enhanced Tolerance Variant This substitute provides tighter tolerance specification (±1% versus ±5%) while maintaining identical power rating upgrade to 0.75W. Selection of this part is appropriate for applications requiring improved resistance accuracy. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical thermal and environmental operating parameters. Inventory availability is 20,680 pieces.

RC2010JK-0768KL (YAGEO) — Tolerance-Matched Power Upgrade This substitute maintains the original ±5% tolerance specification while providing increased power rating to 0.75W. Selection of this part is appropriate for applications where tolerance matching to the original specification is required but enhanced thermal headroom is beneficial. ROHS3 compliance and REACH unaffected status are maintained. Inventory availability is 785 pieces.

Both substitutes are electrically and mechanically compatible with the RC5025J683CS within the 2010 package form factor. Selection between substitutes depends on tolerance and power rating requirements specific to the application circuit.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0768KL or RC2010JK-0768KL be used as direct replacements for RC5025J683CS?

A: Yes. Both substitute parts maintain identical resistance value (68 kOhms), package form factor (2010 / 5025 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and all regulatory compliance certifications (ROHS3, REACH unaffected, EAR99). The substitutes offer enhanced specifications: higher power rating (0.75W versus 0.667W) and, in the case of RC2010FK-0768KL, tighter tolerance (±1% versus ±5%).

Q: What is the difference between the two substitute parts?

A: RC2010FK-0768KL provides ±1% tolerance with 0.75W power rating. RC2010JK-0768KL provides ±5% tolerance (matching the original) with 0.75W power rating. Both are manufactured by YAGEO and are mechanically and electrically compatible. Selection depends on whether tighter tolerance specification is required for the application.

Q: Are the physical dimensions identical between the main part and substitutes?

A: Yes. All three parts share identical length and width dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm) and maximum seated height (0.026" / 0.65-0.66mm). They are mechanically interchangeable within the 2010 package footprint.

Q: What is the significance of the higher power rating in the substitute parts?

A: The substitute parts are rated at 0.75W (3/4W) compared to the original 0.667W (2/3W). This represents a 12.5% increase in power dissipation capability. In applications where the original part operates near its thermal limit, the substitute provides additional thermal margin. The higher power rating does not affect electrical performance or compatibility; it only extends the safe operating envelope.

Q: Are moisture sensitivity levels identical?

A: Yes. All three parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Do all parts meet the same regulatory requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030. Regulatory compliance is maintained across all substitutions.
