Substitute Part Grouping Explanation

Substitute parts for the RC5025J680CS are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain the same 68 Ohm resistance value and operate within the -55°C to 155°C temperature range with ±100ppm/°C temperature coefficient.

Package Compatibility: All substitutes use the identical 2010 (5025 Metric) package with matching physical dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm) and maximum seated height of 0.026" (0.65-0.66mm).

Composition & Features: All substitutes employ thick film construction with moisture-resistant properties, maintaining the same fundamental material technology.

Compliance & Certifications: All substitutes maintain RoHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring regulatory equivalence.

Differentiation Parameters: Substitutes vary in tolerance specification (±1% versus ±5%), power rating (0.75W versus 0.667W), and manufacturer designation. The AC2010FK-0768RL includes automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (RC2010JK-0768RL): This YAGEO part maintains identical tolerance (±5%) and moisture-resistant thick film construction as the main part. The increased power rating (0.75W versus 0.667W) provides additional thermal margin without affecting circuit performance. All compliance certifications (RoHS3, MSL 1) are equivalent. This substitute is suitable for direct replacement in existing designs.

Enhanced Tolerance Substitution (RC2010FK-0768RL): This YAGEO part offers improved tolerance specification (±1% versus ±5%) while maintaining all other electrical and mechanical parameters. The higher power rating (0.75W) and identical package dimensions ensure mechanical compatibility. RoHS3 and MSL 1 compliance are maintained. Selection of this part is appropriate when tighter resistance tolerance is required without design modification.

Automotive-Qualified Substitution (AC2010FK-0768RL): This YAGEO part combines ±1% tolerance with AEC-Q200 automotive qualification. The 0.75W power rating and identical package specifications ensure compatibility. This substitute is specified for applications requiring automotive-grade component certification while maintaining all other electrical and thermal characteristics.

All substitutes maintain Active product status and full regulatory compliance, supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can RC2010JK-0768RL replace RC5025J680CS in any application?

A: Yes. Both parts share identical resistance (68 Ohms), tolerance (±5%), package (2010/5025 Metric), temperature range (-55°C to 155°C), and compliance certifications (RoHS3, MSL 1). The substitute's higher power rating (0.75W versus 0.667W) does not create incompatibility; it provides additional thermal capacity.

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

A: RC2010JK-0768RL maintains ±5% tolerance matching the main part. RC2010FK-0768RL and AC2010FK-0768RL both offer ±1% tolerance. AC2010FK-0768RL additionally includes AEC-Q200 automotive qualification. All three share identical package dimensions and operating temperature range.

Q: Are the physical dimensions identical across all parts?

A: Yes. All parts use the 2010 (5025 Metric) package with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.026" (0.65-0.66mm). They are mechanically interchangeable on PCBs designed for this package format.

Q: Does the higher power rating of substitute parts affect circuit design?

A: No. The substitute parts' 0.75W rating exceeds the main part's 0.667W specification. This provides additional thermal margin and does not alter electrical behavior or circuit performance. The parts are electrically equivalent at the specified resistance and tolerance values.

Q: Which substitute should be selected for automotive applications?

A: AC2010FK-0768RL is specified for automotive applications due to AEC-Q200 qualification. This part maintains all electrical and mechanical compatibility while meeting automotive industry standards.

Q: Are all parts RoHS3 compliant?

A: Yes. The main part RC5025J680CS and all three substitutes (AC2010FK-0768RL, RC2010FK-0768RL, RC2010JK-0768RL) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
