Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S03F3743V is determined by strict alignment of the following parameters:

• Resistance value: 374 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Package: 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: MSL 1 (exact match required)

All identified substitute parts meet these criteria. Variations in features (such as anti-sulfur coating or moisture resistance) and certifications (such as AEC-Q200 automotive rating) do not disqualify substitution but may be relevant for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components with ROHS3 compliance and MSL 1 rating, confirming suitability for direct replacement in applications requiring 374 kOhms ±1% 0.1W 0603 thick film resistors.

ERJ-3EKF3743V (Panasonic) offers the highest inventory availability at 39,053 units and maintains the same manufacturer as the primary part, ensuring consistency in manufacturing process and quality control.

AC0603FR-07374KL and RC0603FR-07374KL (YAGEO) provide moisture-resistant thick film construction. RC0603FR-07374KL offers the largest inventory stock at 73,329 units but is supplied in Cut Tape (CT) & Digi-Reel® packaging rather than standard Tape & Reel format.

CRCW0603374KFKEA (Vishay Dale) and RMCF0603FT374K (Stackpole Electronics Inc) both carry AEC-Q200 automotive qualification matching the primary part's automotive-grade specification.

CR0603-FX-3743ELF (Bourns Inc.) provides moisture-resistant construction with 25,087 units in stock.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF3743V replace ERJ-S03F3743V directly?

A: Yes. Both parts share identical electrical specifications (374 kOhms ±1%, 0.1W), package format (0603), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and compliance ratings (ROHS3, MSL 1). The primary difference is the series designation (ERJ-3EK vs. ERJ-S03) and feature set (standard vs. anti-sulfur coating).

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging provides components on cut tape segments, typically for lower-volume or manual assembly operations. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Are AEC-Q200 rated parts required for this application?

A: AEC-Q200 automotive qualification is present on ERJ-S03F3743V, CRCW0603374KFKEA, and RMCF0603FT374K. If automotive-grade reliability is required, these three options are recommended. Other substitutes (AC0603FR-07374KL, CR0603-FX-3743ELF, RC0603FR-07374KL, ERJ-3EKF3743V) meet all electrical and mechanical specifications but lack explicit AEC-Q200 certification.

Q: Does anti-sulfur coating affect substitution compatibility?

A: Anti-sulfur coating on the ERJ-S03F3743V is a feature that does not affect electrical performance or mechanical fit. Substitute parts without this feature remain electrically and mechanically compatible. Selection of anti-sulfur variants depends on environmental exposure requirements specific to the application.

Q: Can moisture-resistant variants be used interchangeably?

A: Yes. Moisture-resistant construction (present on AC0603FR-07374KL, CR0603-FX-3743ELF, and RC0603FR-07374KL) provides enhanced performance in humid environments but does not affect compatibility with applications designed for standard thick film resistors. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating.
