Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F1740CS is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Resistance: 174 Ohms (exact match required)
• Tolerance: ±1% (substitute must meet or exceed this specification)
• Power Rating: 0.25W minimum (substitute may exceed)
• Package: 1206 (3216 Metric) form factor (exact match for PCB assembly)
• Composition: Thick Film (defines electrical behavior)

Important Compatibility Parameters:

• Temperature Coefficient: ±100ppm/°C (substitute must match)
• Operating Temperature: -55°C ~ 155°C (substitute must cover or exceed this range)
• RoHS3 Compliance: Required for regulatory alignment
• Moisture Sensitivity: MSL 1 classification acceptable

Substitution Categories:

Direct Substitute: RC1206FR-07174RL (YAGEO) - Identical electrical specifications, same package, same series designation protocol, moisture-resistant thick film construction.

Upgrade Substitute: AC1206FR-07174RL (YAGEO) - Meets all critical parameters with addition of AEC-Q200 automotive qualification, providing enhanced reliability for demanding applications.

Similar Substitutes: CRCW1206174RFKEA (Vishay Dale), ERJ-8ENF1740V (Panasonic) - Meet all critical electrical and mechanical parameters with AEC-Q200 automotive qualification. ERJ-8ENF1740V carries "Not For New Designs" status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): RC1206FR-07174RL (YAGEO) is the primary direct substitute. This part maintains identical electrical specifications, package form factor, and moisture-resistant thick film construction. Both the main part and this substitute are Active status products. Selection of this part ensures seamless PCB compatibility and performance equivalence.

For Upgraded Applications: AC1206FR-07174RL (YAGEO) is recommended when AEC-Q200 automotive qualification is required. This part meets all electrical and mechanical parameters of the RC3216F1740CS while adding automotive-grade reliability certification. Active product status ensures long-term availability.

For High-Volume or Alternative Sourcing: CRCW1206174RFKEA (Vishay Dale) provides an alternative source with AEC-Q200 qualification and Active product status. This part meets all critical electrical and mechanical parameters and supports supply chain diversification.

Not Recommended for New Designs: ERJ-8ENF1740V (Panasonic) carries "Not For New Designs" product status. While this part meets all electrical and mechanical specifications with AEC-Q200 qualification, its obsolescence trajectory makes it unsuitable for new product development. Existing designs using this part may continue to source available inventory.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07174RL be used as a direct replacement for RC3216F1740CS?

A: Yes. RC1206FR-07174RL meets all critical electrical parameters (174 Ω ±1%, 0.25W), operates across the identical temperature range (-55°C ~ 155°C), maintains ±100ppm/°C temperature coefficient, and uses the same 1206 (3216 Metric) package. Both parts are moisture-resistant thick film resistors with Active product status and RoHS3 compliance.

Q: What is the difference between the main part and AC1206FR-07174RL?

A: The primary difference is AEC-Q200 automotive qualification present in AC1206FR-07174RL. All electrical specifications (174 Ω ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C) and package form factor remain identical. AC1206FR-07174RL is suitable for automotive and high-reliability applications requiring automotive-grade component certification.

Q: Are there physical dimension differences between substitute parts?

A: Minor dimensional variations exist within acceptable tolerances. RC3216F1740CS and CRCW1206174RFKEA measure 0.126" L × 0.063" W (3.20mm × 1.60mm), while RC1206FR-07174RL and AC1206FR-07174RL measure 0.122" L × 0.063" W (3.10mm × 1.60mm). Height differences range from 0.024" to 0.028" (0.60mm to 0.70mm). These variations fall within standard 1206 package tolerances and do not affect PCB assembly compatibility.

Q: Why is ERJ-8ENF1740V marked "Not For New Designs"?

A: ERJ-8ENF1740V carries "Not For New Designs" status, indicating the manufacturer has discontinued active development and is transitioning this product line. While existing inventory remains available and the part meets all electrical and mechanical specifications, new product designs should select from Active status alternatives such as RC1206FR-07174RL or AC1206FR-07174RL.

Q: Do all substitute parts have MSL 1 rating?

A: Yes. All listed substitute parts carry MSL 1 (Unlimited) moisture sensitivity level classification, matching the RC3216F1740CS specification. This classification indicates unlimited shelf life under normal storage conditions without special moisture control requirements.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant, matching the regulatory requirement of the main part. This ensures compatibility with RoHS3-regulated supply chains and end-use applications.
