Substitute Part Grouping Explanation

Substitution eligibility for the RAVF164DFT100R is determined by the following mandatory parameters:

• Resistance value: 100 Ohm (exact match required)
• Number of resistors: 4 (exact match required)
• Circuit type: Isolated (exact match required)
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals (exact match required)
• Number of pins: 8 (exact match required)
• Mounting type: Surface Mount (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Substitute parts are grouped into three categories based on performance enhancements:

Direct Equivalents maintain all electrical and mechanical specifications of the main part.

Professional Grade Upgrades offer improved tolerance and temperature coefficient performance while maintaining power rating and operating temperature range compatibility.

Precision Grade Upgrades provide the highest tolerance and temperature coefficient specifications, suitable for applications requiring matched resistor networks with minimal drift.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Pin-Compatible, Functional Equivalence):

YC164-FR-07100RL (YAGEO) and CAY16-1000F4LF (Bourns Inc.) are direct functional equivalents. Both maintain ±1% tolerance and ±200ppm/°C temperature coefficient specifications. YC164-FR-07100RL supports the full operating temperature range (-55°C ~ 155°C) matching the main part. CAY16-1000F4LF operates to -55°C ~ 125°C, which is acceptable for applications not requiring the extended upper temperature limit. Both parts are in active production status.

For Performance Upgrade (Professional Grade):

ACASA100021000P100 (Vishay Beyschlag/Draloric/BC Components) offers improved tolerance (±0.5%) and superior temperature coefficient (±50ppm/°C) while maintaining 100mW power per element. This part is suitable for voltage divider applications requiring matched resistor networks. Operating temperature range is -55°C ~ 125°C. Product status is active.

For Precision Applications:

ACASA1000E1000P100 (Vishay Beyschlag/Draloric/BC Components) provides the highest performance specifications with ±0.25% tolerance, ±25ppm/°C temperature coefficient, and resistor matching ratio of ±0.05%. This part is designated "Not For New Designs" and should be used only when existing designs require this specific precision grade or when legacy system compatibility is mandatory.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical package dimensions, ensuring PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can YC164-FR-07100RL replace RAVF164DFT100R in automotive applications?

A: Yes. YC164-FR-07100RL is AEC-Q200 qualified and maintains identical electrical specifications (100 Ohm ±1%, ±200ppm/°C). It supports the full operating temperature range (-55°C ~ 155°C) and is in active production status.

Q: What is the difference between direct equivalents and upgrade parts?

A: Direct equivalents (YC164-FR-07100RL, CAY16-1000F4LF) maintain the same tolerance (±1%) and temperature coefficient (±200ppm/°C) as the main part. Upgrade parts offer improved tolerance and lower temperature coefficient, suitable for precision voltage divider applications.

Q: Can I use CAY16-1000F4LF if my circuit operates above 125°C?

A: No. CAY16-1000F4LF is rated to -55°C ~ 125°C. For applications requiring operation to 155°C, use RAVF164DFT100R or YC164-FR-07100RL.

Q: Why is ACASA1000E1000P100 marked "Not For New Designs"?

A: This designation indicates the manufacturer is phasing out this product line. It should be used only for legacy system maintenance or when existing designs specifically require its precision specifications (±0.25% tolerance, ±25ppm/°C).

Q: Are all substitute parts pin-compatible with the main part?

A: Yes. All substitute parts use the same 1206 (3216 Metric) package with 8 pins and convex, long side terminals. PCB layout modifications are not required.

Q: What is the power rating difference between parts?

A: RAVF164DFT100R, ACASA100021000P100, and ACASA1000E1000P100 are rated at 100mW per element. YC164-FR-07100RL and CAY16-1000F4LF are rated at 62.5mW per element. Select based on circuit power dissipation requirements.
