Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: resistance value (4.7k Ohm), circuit type (Isolated), package format (1206 with 8 pins), mounting type (Surface Mount), and compliance standards (RoHS3, REACH Unaffected). All identified substitutes maintain these core specifications.

Substitute parts are categorized by tolerance and temperature coefficient performance:

Upgrade Category (Enhanced Tolerance): ACASA470124701P100 and ACASA4701E4701P100 provide tighter tolerance specifications (±0.5% and ±0.25% respectively) compared to the original ±1% specification. These parts are suitable for applications requiring improved accuracy.

Manufacturer Recommended Category (Equivalent Performance): CAY16-4701F4LF from Bourns Inc. maintains identical tolerance (±1%) and temperature coefficient (±200ppm/°C) specifications as the original part, with the exception of reduced power per element (62.5mW versus 100mW).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full RoHS3 compliance. Selection between substitutes depends on application-specific requirements:

For applications requiring the original automotive-grade specification with AEC-Q200 qualification and extended operating temperature range to 155°C, the RAVF164DFT4K70 remains the specified component.

ACASA470124701P100 provides improved tolerance performance (±0.5%) and reduced temperature coefficient (±50ppm/°C) suitable for voltage divider applications requiring enhanced accuracy. Operating temperature range is limited to -55°C ~ 125°C.

ACASA4701E4701P100 delivers the highest tolerance specification (±0.25%) with resistor matching ratio of ±0.05% and resistor-ratio-drift of ±7.5ppm/°C, optimized for precision voltage divider circuits. Operating temperature range is -55°C ~ 125°C.

CAY16-4701F4LF from Bourns Inc. maintains electrical specifications identical to the original part (±1% tolerance, ±200ppm/°C temperature coefficient) with equivalent package dimensions. Power per element is reduced to 62.5mW. Operating temperature range is -55°C ~ 125°C.

Frequently Asked Questions (FAQ)

Q: Can ACASA470124701P100 or ACASA4701E4701P100 be used as direct replacements for RAVF164DFT4K70?

A: These Vishay parts are electrically compatible substitutes with identical resistance value, package format, and pin configuration. However, the operating temperature range is limited to -55°C ~ 125°C compared to the original -55°C ~ 155°C specification. Applications requiring the extended upper temperature limit must use the original RAVF164DFT4K70 or CAY16-4701F4LF.

Q: What is the impact of using CAY16-4701F4LF with reduced power per element (62.5mW versus 100mW)?

A: Power per element rating determines the maximum continuous power dissipation in each resistor. Applications with power dissipation requirements exceeding 62.5mW per resistor element require the original RAVF164DFT4K70 or ACASA series parts rated at 100mW.

Q: Are all substitute parts suitable for automotive applications?

A: The original RAVF164DFT4K70 carries AEC-Q200 automotive qualification. The substitute parts (ACASA470124701P100, ACASA4701E4701P100, and CAY16-4701F4LF) do not list automotive grade or AEC-Q200 qualification in their specifications. Applications requiring automotive qualification must use the original part.

Q: What are the dimensional differences between substitute parts?

A: RAVF164DFT4K70 and CAY16-4701F4LF share identical dimensions (0.126" L x 0.063" W, height 0.024"). ACASA470124701P100 and ACASA4701E4701P100 have slightly reduced width (0.059" versus 0.063") and height (0.022" versus 0.024"). These dimensional variations are within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Which substitute part offers the best temperature stability?

A: ACASA4701E4701P100 provides the lowest temperature coefficient at ±25ppm/°C, followed by ACASA470124701P100 at ±50ppm/°C. Both original RAVF164DFT4K70 and CAY16-4701F4LF maintain ±200ppm/°C temperature coefficient.
