Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S03F6651V is determined by strict equivalence across the following parameters:

• Resistance value: 6.65 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Package format: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

All substitute parts listed below meet these criteria. Variations in packaging format (Tape & Reel vs. Cut Tape), minor dimensional tolerances, and manufacturer-specific feature sets (such as automotive AEC-Q200 rating or moisture resistance coating) do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the ERJ-S03F6651V and maintain identical electrical specifications and package dimensions. Selection among these alternatives should be based on:

Availability and Lead Time: ERJ-3EKF6651V (Panasonic) offers the highest inventory level at 175,604 units. RMCF0603FT6K65 (Stackpole) provides 148,443 units. These options support rapid procurement.

Manufacturer Qualification: ERJ-S03F6651V, ERJ-3EKF6651V, CRCW06036K65FKEA, and RMCF0603FT6K65 carry automotive AEC-Q200 certification. AC0603FR-076K65L and RC0603FR-076K65L from YAGEO carry automotive AEC-Q200 and moisture-resistant designations. CR0603-FX-6651ELF from Bourns includes moisture-resistant coating.

Packaging Format: Tape & Reel format is available from Panasonic (ERJ-S03F6651V, ERJ-3EKF6651V), Bourns (CR0603-FX-6651ELF), and Stackpole (RMCF0603FT6K65). Cut Tape & Digi-Reel format is available from YAGEO (AC0603FR-076K65L, RC0603FR-076K65L) and Vishay Dale (CRCW06036K65FKEA).

Compliance: All parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF6651V be used as a direct replacement for ERJ-S03F6651V?

A: Yes. Both parts are manufactured by Panasonic, share identical electrical specifications (6.65 kOhms ±1%, 0.1W, ±100ppm/°C), operate across -55°C to 155°C, and are packaged in 0603 format. The primary difference is series designation (ERJ-3EK vs. ERJ-S03) and significantly higher inventory availability for ERJ-3EKF6651V.

Q: Are YAGEO AC0603FR-076K65L and RC0603FR-076K65L interchangeable?

A: Yes. Both YAGEO parts meet all electrical and mechanical equivalence criteria for the ERJ-S03F6651V. AC0603FR-076K65L includes automotive AEC-Q200 rating, while RC0603FR-076K65L is designated as moisture-resistant. Both are supplied in Cut Tape & Digi-Reel format.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape & Digi-Reel packaging supplies components on cut tape segments with reel availability, suitable for mixed-volume or lower-volume production runs. Electrical and mechanical performance are identical.

Q: Do all substitute parts support automotive applications?

A: ERJ-S03F6651V, ERJ-3EKF6651V, CRCW06036K65FKEA, and RMCF0603FT6K65 carry AEC-Q200 automotive qualification. AC0603FR-076K65L and RC0603FR-076K65L from YAGEO are automotive-rated. CR0603-FX-6651ELF from Bourns does not carry explicit AEC-Q200 designation but meets all electrical and thermal specifications.

Q: Are there dimensional variations among substitute parts?

A: Minor dimensional tolerances exist. ERJ-S03F6651V, AC0603FR-076K65L, and RC0603FR-076K65L specify 0.063" L x 0.031" W (1.60mm x 0.80mm). CRCW06036K65FKEA specifies 0.061" L x 0.033" W (1.55mm x 0.85mm). RMCF0603FT6K65 specifies 0.061" L x 0.031" W (1.55mm x 0.80mm). These variations remain within 0603 package tolerance and do not affect PCB footprint compatibility.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without moisture-related degradation. No baking or special storage conditions are required prior to assembly.
