Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F6653CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 665 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 0402 (1005 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Number of Terminations: 2 (exact match required)

Allowable Variation Parameters:

• Power Rating: Substitutes rated at 0.063W (1/16W) or higher are acceptable. The ERJ-2RKF6653X rated at 0.1W (1/10W) represents an upgrade in thermal capability.
• Packaging Format: Cut Tape (CT) and Tape & Reel (TR) are interchangeable for component sourcing purposes.
• Features: Additional certifications (Automotive AEC-Q200) or enhanced features (Moisture Resistant) do not disqualify substitution.
• Manufacturer: Any manufacturer meeting all mandatory parameters is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection:

RC0402FR-07665KL (YAGEO) is the primary direct equivalent to RC1005F6653CS. Both parts share identical electrical specifications (665 kΩ ±1%, 0.063W), mechanical dimensions, and environmental ratings. This substitute is suitable for applications where Samsung sourcing is unavailable and YAGEO supply is preferred. Inventory availability is significantly higher (413,305 pieces) compared to the original part.

Upgrade Selection for Enhanced Reliability:

ERJ-2RKF6653X (Panasonic Electronic Components) provides an upgrade path with increased power rating (0.1W versus 0.063W) and Automotive AEC-Q200 certification. This part is appropriate for designs requiring automotive-grade qualification or applications with higher thermal stress margins. The upgrade maintains all other electrical and mechanical specifications while providing enhanced thermal dissipation capability.

Automotive-Grade Alternatives:

AC0402FR-07665KL (YAGEO), CRCW0402665KFKED (Vishay Dale), and RMCF0402FT665K (Stackpole Electronics Inc) all provide AEC-Q200 automotive certification at the original 0.063W power rating. These parts are suitable for automotive applications or designs requiring automotive-grade component qualification. AC0402FR-07665KL additionally includes moisture resistant features matching the original part's construction.

Compliance and Regulatory Status:

All identified substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited) moisture sensitivity rating, and REACH unaffected status, ensuring compatibility with standard PCB assembly processes and regulatory requirements applicable to the original RC1005F6653CS.

Frequently Asked Questions (FAQ)

Q: Can ERJ-2RKF6653X be used as a direct replacement for RC1005F6653CS?

A: ERJ-2RKF6653X is electrically and mechanically compatible with RC1005F6653CS. The primary difference is the enhanced power rating (0.1W versus 0.063W) and Automotive AEC-Q200 certification. In applications where the original 0.063W rating is sufficient, the higher power rating of ERJ-2RKF6653X does not create incompatibility. The part occupies the same PCB footprint and operates within the identical temperature range.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape and Tape & Reel are packaging formats for component delivery. Cut Tape provides components in smaller quantities on individual tape segments, while Tape & Reel supplies components on continuous reels for automated assembly. Both formats contain identical components. Selection depends on procurement volume and assembly equipment compatibility. For design purposes, CT and TR versions of the same part number are functionally equivalent.

Q: Are the YAGEO RC0402FR-07665KL and AC0402FR-07665KL interchangeable?

A: RC0402FR-07665KL and AC0402FR-07665KL are both YAGEO 665 kΩ ±1% 0402 resistors with identical electrical specifications. AC0402FR-07665KL includes Automotive AEC-Q200 certification and moisture resistant features, while RC0402FR-07665KL does not carry automotive certification. In non-automotive applications, RC0402FR-07665KL is the direct equivalent. In automotive applications, AC0402FR-07665KL is the appropriate selection.

Q: Does the height difference between AC0402FR-07665KL (0.015" max) and other substitutes (0.016" max) affect PCB assembly?

A: The 0.001" (0.03mm) height difference is within standard PCB assembly tolerances and does not affect component placement, reflow soldering, or electrical performance. Both heights are acceptable for 0402 package specifications. This minor variation does not disqualify AC0402FR-07665KL as a substitute.

Q: Which substitute part offers the best supply availability?

A: RC0402FR-07665KL (YAGEO) provides the highest inventory availability with 413,305 pieces in stock, compared to 692 pieces of the original RC1005F6653CS. RMCF0402FT665K (Stackpole) offers 53,719 pieces, and CRCW0402665KFKED (Vishay) provides 35,498 pieces. ERJ-2RKF6653X (Panasonic) has 163,159 pieces available.

Q: Are all substitute parts ROHS3 compliant?

A: All identified substitute parts (RC0402FR-07665KL, ERJ-2RKF6653X, AC0402FR-07665KL, CRCW0402665KFKED, and RMCF0402FT665K) are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, matching the regulatory status of RC1005F6653CS.

Q: Can I use an automotive-grade substitute in a non-automotive application?

A: Automotive-grade parts (ERJ-2RKF6653X, AC0402FR-07665KL, CRCW0402665KFKED, RMCF0402FT665K) meet or exceed the electrical and environmental specifications of non-automotive equivalents. Using automotive-grade components in non-automotive applications does not create incompatibility and may provide enhanced reliability margins. Selection should be based on cost, availability, and design requirements.
