Substitute Part Grouping Explanation

Substitute parts for the RC5025J132CS are qualified based on the following substitution criteria:

Mandatory Matching Parameters:

• Resistance value: 1.3 kOhms (exact match required)
• Package / Case: 2010 (5025 Metric) (mechanical compatibility)
• Composition: Thick Film (technology consistency)
• Operating temperature range: -55°C ~ 155°C (environmental compatibility)
• Temperature coefficient: ±100ppm/°C (stability matching)
• Moisture resistance: Required feature
• RoHS3 compliance: Required regulatory status
• MSL rating: 1 (Unlimited) or equivalent

Allowable Parameter Variations:

• Tolerance: May be equal or tighter (±5% or better)
• Power rating: May be equal or higher (0.667W or greater)
• Additional certifications: May include automotive or industrial qualifications without affecting substitution validity

The AC2010FK-071K3L qualifies as a direct substitute based on matching all mandatory parameters while providing improved tolerance (±1% versus ±5%) and increased power rating (0.75W versus 0.667W).

Parameter Comparison

Engineering Selection Recommendations

The AC2010FK-071K3L represents a qualified substitute for the RC5025J132CS based on electrical and mechanical parameter alignment. Selection between these components should be based on the following engineering considerations:

Use RC5025J132CS when:

• Bulk packaging format is required for assembly processes
• Standard tolerance ±5% specification is acceptable for the application
• Samsung Electro-Mechanics supply chain preference exists

Use AC2010FK-071K3L when:

• Tape & Reel packaging format is required for automated assembly
• Tighter tolerance ±1% improves circuit performance or measurement accuracy
• Higher power rating 0.75W provides additional thermal margin
• AEC-Q200 automotive qualification is required or beneficial for supply chain continuity
• YAGEO component availability or pricing is advantageous

Both components maintain identical mechanical footprint (2010 / 5025 Metric), operating temperature range (-55°C ~ 155°C), and regulatory compliance (RoHS3, REACH Unaffected). The substitute part provides specification improvements without introducing compatibility risk.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-071K3L be used as a direct replacement for RC5025J132CS in existing designs?

A: Yes. The AC2010FK-071K3L is mechanically and electrically compatible. Both components share identical 2010 (5025 Metric) package dimensions, resistance value (1.3 kOhms), operating temperature range (-55°C ~ 155°C), and temperature coefficient (±100ppm/°C). The substitute provides tighter tolerance (±1% versus ±5%) and higher power rating (0.75W versus 0.667W), which are improvements that do not create compatibility issues.

Q: What is the significance of the tolerance difference between ±5% and ±1%?

A: Tolerance defines the allowable deviation from the nominal resistance value. The RC5025J132CS tolerance of ±5% permits resistance values between 1.235 kOhms and 1.365 kOhms. The AC2010FK-071K3L tolerance of ±1% restricts values to between 1.287 kOhms and 1.313 kOhms. Tighter tolerance improves circuit accuracy and reduces performance variation across production batches. Applications requiring precise resistance values benefit from the ±1% specification.

Q: Does the higher power rating of AC2010FK-071K3L affect circuit design?

A: No negative effect occurs. The AC2010FK-071K3L power rating of 0.75W exceeds the RC5025J132CS rating of 0.667W. Higher power rating indicates greater thermal dissipation capacity, providing additional safety margin in applications where the component operates near its thermal limits. This is a specification improvement that does not require design modification.

Q: Are the physical dimensions identical between these components?

A: Yes. Both components use the 2010 (5025 Metric) package with dimensions 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of approximately 0.026" (0.65-0.66mm). Mechanical compatibility is confirmed for PCB layout and assembly processes.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging (RC5025J132CS) supplies components in loose form, suitable for manual assembly or small-scale production. Tape & Reel packaging (AC2010FK-071K3L) presents components in continuous tape format on reels, optimized for automated pick-and-place assembly equipment. Packaging selection depends on manufacturing process requirements, not component performance.

Q: Does AEC-Q200 automotive qualification on AC2010FK-071K3L restrict its use to automotive applications?

A: No. AEC-Q200 is an automotive industry qualification standard that indicates the component meets stringent reliability and quality requirements. Components with AEC-Q200 certification are suitable for automotive applications and are equally valid for industrial, consumer, and other non-automotive applications. The certification represents an additional quality assurance level, not a usage restriction.

Q: Are both components RoHS3 compliant?

A: Yes. Both RC5025J132CS and AC2010FK-071K3L carry RoHS3 compliance certification, confirming absence of restricted substances (lead, cadmium, mercury, hexavalent chromium, PBBs, PBDEs) within regulatory limits. Both components are suitable for applications requiring RoHS compliance.

Q: What does MSL 1 (Unlimited) moisture sensitivity rating mean?

A: MSL 1 indicates the lowest moisture sensitivity level. Components with MSL 1 rating require no special moisture protection during storage, handling, or assembly. "Unlimited" means there is no time restriction for component shelf life or exposure to ambient humidity conditions. Both components feature this rating, confirming robust moisture resistance suitable for standard manufacturing environments.
