Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F6340CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 634 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)

Mechanical Parameters:

• Package type: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS3 Compliant status (required)
• MSL Level 1 (Unlimited) (required)

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within standard tolerances and differences in specific feature sets (such as automotive AEC-Q200 certification) do not affect substitution eligibility when all core parameters align.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

AC1206FR-07634RL (YAGEO) and RC1206FR-07634RL (YAGEO) are both Active products suitable for new designs. AC1206FR-07634RL includes automotive AEC-Q200 certification, making it appropriate for automotive applications. RC1206FR-07634RL provides standard industrial-grade performance without automotive qualification. Both maintain full electrical and mechanical equivalence to the RCS3216F6340CS.

CRCW1206634RFKEA (Vishay Dale) is an Active product with automotive AEC-Q200 certification and the highest inventory availability (25647 units). This part is suitable for both automotive and industrial applications requiring AEC-Q200 compliance.

Secondary Substitute (Legacy Status):

ERJ-8ENF6340V (Panasonic Electronic Components) carries a "Not For New Designs" product status. This part maintains full electrical and mechanical equivalence but should be used only for replacement or repair of existing assemblies. New design implementations should utilize Active-status alternatives.

Selection Criteria:

• For automotive applications: Select AC1206FR-07634RL or CRCW1206634RFKEA (both AEC-Q200 certified)
• For industrial applications: Select RC1206FR-07634RL or CRCW1206634RFKEA
• For new designs: Avoid ERJ-8ENF6340V
• For maximum inventory availability: Select CRCW1206634RFKEA or RC1206FR-07634RL

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-07634RL replace RCS3216F6340CS in any application?

A: Yes. AC1206FR-07634RL meets all electrical and mechanical parameters required for direct substitution. The addition of automotive AEC-Q200 certification does not restrict its use in non-automotive applications.

Q: What is the difference between AC1206FR-07634RL and RC1206FR-07634RL?

A: Both are YAGEO 1206 634 Ohm ±1% resistors with identical electrical specifications. AC1206FR-07634RL includes automotive AEC-Q200 certification; RC1206FR-07634RL does not. For applications not requiring automotive qualification, either part is functionally equivalent.

Q: Why is ERJ-8ENF6340V marked "Not For New Designs"?

A: This designation indicates the part is in legacy status. While it maintains full electrical and mechanical equivalence, Panasonic has discontinued active development and support for this series. New designs should utilize Active-status alternatives to ensure long-term supply chain stability and manufacturer support.

Q: Are there physical dimension differences between these substitutes?

A: Minor variations exist within standard tolerances. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), and height ranges from 0.024" to 0.028" (0.60mm to 0.70mm). These variations fall within acceptable PCB design tolerances and do not affect substitution eligibility.

Q: Do all substitutes have the same moisture sensitivity level?

A: Yes. All listed substitutes maintain MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute has the best inventory availability?

A: RC1206FR-07634RL (YAGEO) has the highest inventory at 56982 units, followed by CRCW1206634RFKEA (Vishay Dale) at 25647 units.

Q: Can CRCW1206634RFKEA be used in non-automotive applications?

A: Yes. AEC-Q200 certification indicates automotive-grade reliability and does not restrict use in industrial or consumer applications. CRCW1206634RFKEA is suitable for any application requiring a 634 Ohm ±1% 1/4W 1206 resistor.
