RAVF164DFT100K Equivalent & Substitute Parts

Part Overview

The RAVF164DFT100K is a 4-resistor network array manufactured by Stackpole Electronics Inc, featuring 100k Ohm ±1% tolerance with 100mW power per element in a 1206 (3216 Metric) surface mount package. This isolated resistor array is designed for applications requiring matched resistor networks with automotive-grade reliability (AEC-Q200). The part is currently active in production. Substitute parts are identified when design requirements demand enhanced precision, improved temperature stability, or alternative manufacturer sourcing while maintaining functional compatibility within the 1206 package footprint and isolated circuit topology.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RAVF164DFT100K are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 100k Ohm
• Circuit type: Isolated
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals
• Number of resistors: 4
• Number of pins: 8
• Mounting type: Surface Mount
• RoHS3 compliance

Allowable Variation Parameters:

• Tolerance: May be equal or tighter (±1%, ±0.5%, ±0.25%)
• Temperature coefficient: May be equal or lower (±200ppm/°C, ±50ppm/°C, ±25ppm/°C)
• Power per element: May be equal or higher (100mW, 62.5mW)
• Operating temperature range: May be equal or wider
• Product status: Active or Not For New Designs

Three substitute parts meet these criteria, each offering different performance characteristics while maintaining functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

ACASA100321003P100 (Vishay - Professional Grade): This substitute offers tighter tolerance (±0.5%) and superior temperature stability (±50ppm/°C) compared to the RAVF164DFT100K while maintaining identical power rating and package dimensions. Product status is Active, making it suitable for new designs. Operating temperature range is reduced to -55°C ~ 125°C. Select this part when enhanced precision and temperature coefficient performance are required within the standard operating range.

ACASA1003E1003P100 (Vishay - Precision Grade): This substitute provides the highest precision available (±0.25% tolerance, ±25ppm/°C temperature coefficient) with specified resistor matching ratio (±0.05%) and resistor-ratio-drift (±7.5ppm/°C). Product status is Not For New Designs, limiting its use to legacy system support or existing design continuations. Operating temperature range is -55°C ~ 125°C. Select this part only when existing designs specifically require this precision level and product status constraints are acceptable.

CAY16-1003F4LF (Bourns - Manufacturer Recommended): This substitute maintains identical tolerance (±1%) and temperature coefficient (±200ppm/°C) as the RAVF164DFT100K, providing direct functional equivalence. Power per element is reduced to 62.5mW. Product status is Active. Operating temperature range is -55°C ~ 125°C. Select this part for direct replacement when manufacturer sourcing diversity is required or when the reduced power rating is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can ACASA100321003P100 be used as a direct drop-in replacement for RAVF164DFT100K?

A: Yes. Both parts share identical resistance value (100k Ohm), circuit type (Isolated), package (1206 with 8 pins), and power rating (100mW per element). The ACASA100321003P100 offers improved tolerance (±0.5% vs ±1%) and temperature coefficient (±50ppm/°C vs ±200ppm/°C). Operating temperature range differs: ACASA100321003P100 operates to 125°C maximum versus 155°C for RAVF164DFT100K.

Q: What is the difference between ACASA100321003P100 and ACASA1003E1003P100?

A: Both are Vishay products in the same package. ACASA1003E1003P100 offers superior precision (±0.25% tolerance vs ±0.5%, ±25ppm/°C vs ±50ppm/°C) and includes resistor matching specifications (±0.05% matching ratio, ±7.5ppm/°C drift). However, ACASA1003E1003P100 has product status "Not For New Designs," restricting its use to legacy applications. ACASA100321003P100 is Active and recommended for new designs.

Q: Why does CAY16-1003F4LF have lower power per element (62.5mW vs 100mW)?

A: CAY16-1003F4LF is a Bourns product with different internal design characteristics. The reduced power rating does not affect functional compatibility if the application circuit operates within 62.5mW per element limits. Verify application power requirements before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RAVF164DFT100K, ACASA100321003P100, ACASA1003E1003P100, and CAY16-1003F4LF are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the maximum operating temperature for each part?

A: RAVF164DFT100K operates to 155°C. ACASA100321003P100, ACASA1003E1003P100, and CAY16-1003F4LF all operate to 125°C maximum. Applications requiring operation above 125°C must use RAVF164DFT100K.

Q: Can I use CAY16-1003F4LF in automotive applications?

A: CAY16-1003F4LF specifications do not list AEC-Q200 qualification. RAVF164DFT100K is explicitly qualified for Automotive AEC-Q200. Verify automotive qualification requirements with application specifications before substitution.
