Key Parameters

Substitute Part Grouping Explanation

Substitution of the RLC16K1R80FTP is determined by strict alignment of the following critical parameters:

Electrical Parameters:

• Resistance value: 1.8 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Thick Film (exact match required)

Mechanical Parameters:

• Package / Case: 0603 (1608 Metric) (exact match required)
• Physical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm) (exact match required)
• Number of terminations: 2 (exact match required)

Environmental & Compliance Parameters:

• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Parameter Variance Permitted:

• Power rating: Substitute parts may have equal or higher power rating
• Temperature coefficient: Substitute parts may have different temperature coefficient values
• Specific features: Additional features (such as current sense capability) do not disqualify substitution

The ERJ-3RQF1R8V meets all critical substitution criteria with the exception of power rating, which is lower (0.1W vs. 0.25W). This variance requires application-level verification to ensure the substitute part's power dissipation capability is adequate for the intended circuit.

Engineering Selection Recommendations

Primary Part: RLC16K1R80FTP

The RLC16K1R80FTP is the specified component and should be used when available. It is an active product with established supply (787 pieces in stock) and meets all automotive AEC-Q200 requirements with full ROHS3 compliance.

Substitute Part: ERJ-3RQF1R8V

The ERJ-3RQF1R8V from Panasonic Electronic Components is a qualified substitute for the RLC16K1R80FTP with the following conditions:

1. Mechanical Compatibility: The 0603 (1608 Metric) package, physical dimensions, and termination count are identical. PCB layout and assembly processes require no modification.

2. Electrical Compatibility: Resistance value (1.8 Ohms) and tolerance (±1%) are exact matches. Both parts are thick film composition with identical operating temperature range (-55°C ~ 155°C).

3. Compliance Status: Both parts are AEC-Q200 qualified for automotive applications, ROHS3 compliant, and have MSL 1 (Unlimited) moisture sensitivity rating.

4. Power Rating Consideration: The ERJ-3RQF1R8V has a lower power rating (0.1W vs. 0.25W). Circuit design must ensure that actual power dissipation in the resistor does not exceed 0.1W under maximum operating conditions.

5. Temperature Coefficient Variance: The ERJ-3RQF1R8V has a temperature coefficient of ±200ppm/°C compared to ±100ppm/°C for the RLC16K1R80FTP. This difference may affect circuit performance in temperature-sensitive applications.

6. Supply Availability: The ERJ-3RQF1R8V has significantly higher inventory availability (85,350 pieces in stock) compared to the primary part.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-3RQF1R8V be used as a direct replacement for the RLC16K1R80FTP?

A: The ERJ-3RQF1R8V is mechanically and electrically compatible in terms of resistance value, tolerance, package format, and operating temperature range. However, the lower power rating (0.1W vs. 0.25W) requires circuit-level analysis to confirm that actual power dissipation does not exceed the substitute part's capability. The higher temperature coefficient (±200ppm/°C vs. ±100ppm/°C) may also impact precision-dependent applications.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Power rating—the substitute part is rated at 0.1W compared to 0.25W for the main part; (2) Temperature coefficient—the substitute part has ±200ppm/°C versus ±100ppm/°C; (3) Manufacturer—Panasonic versus Kamaya Inc.; (4) Additional features—the substitute part includes current sense capability. All other parameters, including resistance, tolerance, package, dimensions, operating temperature range, and automotive qualification, are identical.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the RLC16K1R80FTP and ERJ-3RQF1R8V are AEC-Q200 qualified for automotive use. Both are ROHS3 compliant and have MSL 1 (Unlimited) moisture sensitivity rating, making them suitable for automotive assembly and environmental conditions.

Q: What is the impact of the different temperature coefficients?

A: The RLC16K1R80FTP has a temperature coefficient of ±100ppm/°C, while the ERJ-3RQF1R8V has ±200ppm/°C. This means the substitute part's resistance value will drift more significantly across the operating temperature range (-55°C ~ 155°C). In circuits where precise resistance stability over temperature is critical, this difference may be significant.

Q: Can the substitute part handle the same power dissipation as the main part?

A: No. The ERJ-3RQF1R8V is rated for 0.1W (1/10W) maximum power dissipation, while the RLC16K1R80FTP is rated for 0.25W (1/4W). If the circuit design requires the full 0.25W capability, the substitute part cannot be used. Circuit analysis must confirm that actual power dissipation remains below 0.1W.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 0603 (1608 Metric) package with identical dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm) and maximum seated height of 0.022" (0.55mm). No PCB layout or assembly modifications are required for package compatibility.

Q: What is the difference in supply availability?

A: The RLC16K1R80FTP has 787 pieces in stock, while the ERJ-3RQF1R8V has 85,350 pieces in stock. The substitute part offers significantly higher availability for high-volume production requirements.

Q: Do both parts have the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) format, which is standard for automated PCB assembly processes.
