Substitute Part Grouping Explanation

Substitute parts for the RC5025F1691CS are identified based on strict equivalence of the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 1.69 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match or better)

Mechanical Compatibility Requirements:

• Package format: 2010 (5025 Metric) (exact match)
• Composition: Thick Film (exact match)
• Number of terminations: 2 (exact match)
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) (exact match)

Compliance Requirements:

• RoHS3 compliance (maintained)
• Moisture resistance feature (maintained)
• MSL rating: 1 (Unlimited) (maintained or equivalent)

The substitute part AC2010FK-071K69L from YAGEO meets all electrical and mechanical equivalence criteria. The power rating of the substitute (0.75W / 3/4W) exceeds the original specification (0.667W / 2/3W), providing enhanced thermal performance while maintaining all other parameters within specification.

Parameter Comparison

Engineering Selection Recommendations

The AC2010FK-071K69L from YAGEO is a direct substitute for the RC5025F1691CS from Samsung Electro-Mechanics. Both components maintain identical electrical specifications (1.69 kOhms ±1%, ±100ppm/°C temperature coefficient) and mechanical compatibility (2010 package, 5.00mm x 2.50mm dimensions). Both parts are ROHS3 compliant with MSL 1 rating and moisture-resistant thick film construction.

The YAGEO substitute provides enhanced power dissipation capability (0.75W versus 0.667W), which represents a performance advantage in thermal management without introducing any compatibility concerns. The YAGEO AC2010FK-071K69L additionally carries AEC-Q200 automotive qualification, which extends the component's suitability to automotive applications while maintaining full compatibility with general industrial and commercial applications.

Both components operate across the identical temperature range (-55°C to 155°C) and share equivalent physical dimensions and termination specifications. Selection between these parts may be based on supply chain availability, packaging format requirements (the YAGEO part is supplied in Tape & Reel format), or application-specific automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-071K69L replace RC5025F1691CS in existing designs?

A: Yes. The AC2010FK-071K69L is electrically and mechanically equivalent to the RC5025F1691CS. Both components have identical resistance values (1.69 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and package format (2010 / 5025 Metric). The substitute's higher power rating (0.75W versus 0.667W) provides additional thermal margin without affecting circuit performance.

Q: Are the physical dimensions identical?

A: Yes. Both the RC5025F1691CS and AC2010FK-071K69L share 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 compatibility with PCB layouts and assembly processes designed for the 2010 package format.

Q: What is the difference in power rating between these parts?

A: The RC5025F1691CS is rated for 0.667W (2/3W) continuous power dissipation, while the AC2010FK-071K69L is rated for 0.75W (3/4W). The substitute part's higher power rating indicates superior thermal performance and allows operation at higher power levels without exceeding temperature limits. This represents an enhancement rather than a limitation.

Q: Are both parts RoHS compliant?

A: Yes. Both the RC5025F1691CS and AC2010FK-071K69L are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity level ratings. Both components feature moisture-resistant thick film construction and are suitable for applications requiring environmental compliance.

Q: What is the significance of AEC-Q200 qualification on the YAGEO part?

A: AEC-Q200 is an automotive industry qualification standard. The AC2010FK-071K69L's AEC-Q200 rating indicates the component meets automotive reliability and performance requirements. This qualification extends the part's applicability to automotive and high-reliability applications while maintaining full compatibility with general industrial and commercial use cases.

Q: What packaging formats are available?

A: The RC5025F1691CS is supplied in standard packaging format. The AC2010FK-071K69L is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. Both formats contain equivalent components with identical electrical and mechanical specifications.

Q: Are the temperature coefficients identical?

A: Yes. Both components have a temperature coefficient of ±100ppm/°C and operate across the identical temperature range of -55°C to 155°C. This ensures equivalent frequency stability and thermal performance characteristics across all operating conditions.
