RAVF164DFT47K0 Equivalent & Substitute Parts

Part Overview

The RAVF164DFT47K0 is a 4-resistor network array manufactured by Stackpole Electronics Inc, featuring 47kΩ ±1% isolated resistors rated at 100mW per element in a 1206 (3216 Metric) surface mount package. This component is designed for applications requiring matched resistor networks with automotive-grade reliability (AEC-Q200 qualified). The part is currently in active production status with 1006 units in stock.

Substitute parts are necessary when design requirements demand improved tolerance specifications, enhanced temperature stability, or when primary component availability is constrained. Alternative manufacturers provide equivalent functionality with varying performance characteristics suitable for different application requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the RAVF164DFT47K0 is determined by the following critical parameters:

• Resistance Value: Must be 47kΩ
• Number of Resistors: Must be 4 elements
• Circuit Type: Must be Isolated configuration
• Package Type: Must be 1206 (3216 Metric) with matching terminal configuration
• Number of Pins: Must be 8
• Mounting Type: Must be Surface Mount
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The substitute parts listed below meet all mandatory compatibility criteria. Variations in tolerance, temperature coefficient, power rating, and operating temperature range represent performance upgrades or trade-offs suitable for specific application contexts.

Parameter Comparison

Engineering Selection Recommendations

CAY16-4702F4LF (Bourns Inc.) — Manufacturer-recommended substitute. Maintains identical tolerance (±1%) and temperature coefficient (±200ppm/°C) specifications as the primary part. Active product status ensures long-term availability. Primary consideration: power rating is reduced to 62.5mW per element and maximum operating temperature is limited to 125°C. Select this substitute when Bourns supply chain preference is required and thermal/power constraints are within application limits.

ACASA470224702P100 (Vishay) — Professional-grade upgrade option. Improves tolerance to ±0.5% and reduces temperature coefficient to ±50ppm/°C, providing enhanced stability for precision applications. Maintains 100mW power rating and active product status. Operating temperature maximum is 125°C. Select this substitute when improved tolerance and temperature stability are required within the 125°C operating range.

ACASA4702E4702P100 (Vishay) — Precision-grade option with highest tolerance specification (±0.25%) and lowest temperature coefficient (±25ppm/°C). Includes resistor matching ratio of ±0.05% and resistor-ratio-drift of ±7.5ppm/°C. Product status is "Not For New Designs," indicating this part is in mature phase with limited future support. Select only for legacy system maintenance or when precision specifications are critical and design freeze is acceptable.

Frequently Asked Questions (FAQ)

Q: Can CAY16-4702F4LF replace RAVF164DFT47K0 in automotive applications?

A: Yes, for applications operating below 125°C. Both parts are ROHS3 compliant with MSL 1 rating. The CAY16-4702F4LF is manufacturer-recommended and maintains identical tolerance and temperature coefficient. However, verify that the reduced power rating (62.5mW vs. 100mW per element) is acceptable for your circuit design.

Q: What is the primary advantage of ACASA470224702P100 over the original part?

A: The ACASA470224702P100 provides improved tolerance (±0.5% vs. ±1%) and significantly better temperature stability (±50ppm/°C vs. ±200ppm/°C). These characteristics make it suitable for precision voltage divider applications and circuits requiring tighter component matching. Operating temperature range is limited to 125°C.

Q: Why is ACASA4702E4702P100 marked "Not For New Designs"?

A: This designation indicates the part is in mature production phase with no planned enhancements or extended support. While currently available (1069 units in stock), Vishay does not recommend this part for new circuit designs. Use only for replacement in existing systems or when precision specifications (±0.25% tolerance, ±25ppm/°C TCR) are mandatory and alternative options are unsuitable.

Q: Are all substitute parts pin-compatible with the original RAVF164DFT47K0?

A: Yes. All listed substitutes maintain the 8-pin configuration in 1206 (3216 Metric) package with convex, long side terminals. Physical dimensions and mounting characteristics are compatible with existing PCB layouts designed for the RAVF164DFT47K0.

Q: What is the maximum operating temperature difference between the main part and substitutes?

A: The RAVF164DFT47K0 operates to 155°C, while all three substitute parts are limited to 125°C maximum. Applications requiring operation above 125°C must use the original Stackpole part or verify thermal performance through detailed analysis.

Q: Do all parts maintain the same moisture sensitivity rating?

A: Yes. All parts listed carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.
