Substitute Part Grouping Explanation

Substitute parts for the AC0201FR-0734R8L are qualified based on the following critical parameters:

• Resistance value: 34.8 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Three qualified substitutes meet all electrical and mechanical parameters:

1. RC0201FR-0734R8L (YAGEO RC_L series) — Upgrade option with higher inventory availability
2. RMCF0201FT34R8 (Stackpole Electronics Inc RMCF series) — Direct alternative with AEC-Q200 rating
3. ERJ-1GNF34R8C (Panasonic Electronic Components ERJ-1GN series) — Upgrade option with highest inventory availability

Parameter Comparison

Engineering Selection Recommendations

AC0201FR-0734R8L (Primary Part): Recommended for applications requiring AEC-Q200 automotive qualification with extended operating temperature range to 155°C. Suitable for automotive and high-reliability applications.

RC0201FR-0734R8L (YAGEO Upgrade): Functionally equivalent within the specified parameter set. Offers significantly higher inventory availability (10,699 units). Operating temperature range limited to 125°C. Suitable for non-automotive or standard industrial applications where the extended temperature range is not required.

RMCF0201FT34R8 (Stackpole Alternative): Direct substitute with AEC-Q200 automotive qualification and extended operating temperature range to 155°C. Maintains all critical electrical parameters. Height specification differs slightly (0.011" vs 0.010" maximum seated height). Suitable for automotive applications requiring alternative sourcing.

ERJ-1GNF34R8C (Panasonic Upgrade): Functionally equivalent within the specified parameter set. Highest inventory availability (33,953 units). Operating temperature range limited to 125°C. Suitable for high-volume production or applications where extended temperature range is not required.

Frequently Asked Questions (FAQ)

Q: Can RC0201FR-0734R8L replace AC0201FR-0734R8L in automotive applications?

A: RC0201FR-0734R8L is electrically and mechanically compatible but lacks specified AEC-Q200 automotive qualification. It is suitable for non-automotive applications. For automotive designs requiring AEC-Q200 compliance, use RMCF0201FT34R8 or maintain AC0201FR-0734R8L.

Q: What is the difference between the operating temperature ranges?

A: AC0201FR-0734R8L and RMCF0201FT34R8 operate from -55°C to 155°C. RC0201FR-0734R8L and ERJ-1GNF34R8C operate from -55°C to 125°C. Select based on application temperature requirements.

Q: Are all substitutes available in the same packaging format?

A: All four parts are supplied in Tape & Reel (TR) packaging in 0201 (0603 Metric) case format. Physical dimensions are equivalent with negligible height variation (0.010" to 0.011" maximum seated height).

Q: Which substitute offers the best supply availability?

A: ERJ-1GNF34R8C provides the highest current inventory at 33,953 units, followed by RC0201FR-0734R8L at 10,699 units. RMCF0201FT34R8 maintains 1,573 units in stock.

Q: Are all parts RoHS3 compliant?

A: All four parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting environmental and regulatory requirements.
