RLC16K2R20FTP Equivalent & Substitute Parts

Part Overview

The RLC16K2R20FTP is a 2.2 Ohm ±1% 0.25W (1/4W) chip resistor manufactured by Kamaya Inc. in the 0603 (1608 Metric) package format. This component is an active product designed for automotive applications with AEC-Q200 qualification. The thick film composition and automotive-grade specifications make it suitable for demanding environments requiring temperature stability across -55°C to 155°C operating range. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require component alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RLC16K2R20FTP is determined by strict adherence to the following critical parameters:

Electrical Parameters:

• Resistance value: 2.2 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Thick Film (required for performance consistency)

Mechanical Parameters:

• Package format: 0603 (1608 Metric) (required for PCB compatibility)
• Physical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm) (required for placement)
• Number of terminations: 2 (required for circuit connection)

Environmental & Compliance Parameters:

• Automotive qualification: AEC-Q200 (required for automotive applications)
• Operating temperature range: -55°C ~ 155°C (required for thermal compatibility)
• RoHS3 compliance (required for regulatory alignment)
• Moisture Sensitivity Level 1 (required for storage and handling compatibility)

The ERJ-3RQF2R2V from Panasonic Electronic Components meets all critical substitution criteria. While the power rating differs (0.1W versus 0.25W), this represents a conservative design margin in the substitute part and does not prevent functional substitution in applications where the original 0.25W rating was specified.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-3RQF2R2V is a valid substitute for the RLC16K2R20FTP based on the following engineering criteria:

Electrical Compatibility: Both components provide identical resistance (2.2 Ohms) and tolerance (±1%), ensuring circuit performance remains within design specifications. The substitute part's lower power rating (0.1W versus 0.25W) does not compromise functionality in applications where the original specification was selected with design margin.

Mechanical Compatibility: Identical package format (0603), physical dimensions, and termination count ensure direct PCB placement compatibility without layout modifications.

Compliance & Certification: Both components carry AEC-Q200 automotive qualification, ROHS3 compliance, and identical moisture sensitivity ratings. These certifications confirm suitability for automotive environments and regulatory requirements.

Thermal Performance: Both components operate across the identical temperature range (-55°C ~ 155°C). The substitute part exhibits a higher temperature coefficient (±200ppm/°C versus ±100ppm/°C), which represents a measurable but acceptable variance for most automotive circuit applications.

Product Status: Both components maintain active product status with established supply chains, ensuring long-term availability for production and field service applications.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-3RQF2R2V replace the RLC16K2R20FTP in all applications?

A: The ERJ-3RQF2R2V is electrically and mechanically compatible with the RLC16K2R20FTP. Both components share identical resistance, tolerance, package format, and operating temperature range. The substitute part's lower power rating (0.1W) does not prevent substitution in applications where the original 0.25W specification was selected with design margin. Circuit-specific power dissipation analysis is required to confirm the substitute part's adequacy for applications operating at maximum power levels.

Q: What is the difference in temperature coefficient between these parts?

A: The RLC16K2R20FTP exhibits a temperature coefficient of ±100ppm/°C, while the ERJ-3RQF2R2V exhibits ±200ppm/°C. This difference indicates the substitute part's resistance value will drift at twice the rate across the operating temperature range. For precision circuits requiring tight temperature stability, this variance must be evaluated against circuit tolerance requirements.

Q: Are both components suitable for automotive applications?

A: Yes. Both the RLC16K2R20FTP and ERJ-3RQF2R2V carry AEC-Q200 automotive qualification, confirming suitability for automotive environments. Both components are ROHS3 compliant and carry identical moisture sensitivity ratings (MSL 1), meeting automotive supply chain and regulatory requirements.

Q: Will the substitute part fit the same PCB footprint?

A: Yes. Both components use the 0603 (1608 Metric) package format with identical physical dimensions (0.063" L x 0.031" W) and maximum seated height (0.022"). No PCB layout modifications are required for component substitution.

Q: What is the significance of the power rating difference?

A: The RLC16K2R20FTP is rated for 0.25W (1/4W) while the ERJ-3RQF2R2V is rated for 0.1W (1/10W). The substitute part's lower rating indicates reduced maximum continuous power dissipation capability. Applications requiring sustained power dissipation above 0.1W must retain the original part specification. Applications operating below 0.1W continuous dissipation can safely use the substitute part.

Q: Are packaging and moisture sensitivity considerations identical?

A: Yes. Both components are supplied in Tape & Reel (TR) packaging and carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture bake-out requirements prior to soldering. Storage and handling procedures are identical for both parts.
