RJ1206FRE073R3L Equivalent & Substitute Parts

Part Overview

The RJ1206FRE073R3L is a 3.3 Ohm ±1% thin film chip resistor in 1206 (3216 Metric) package rated at 0.125W (1/8W) with moisture resistant characteristics. Manufactured by YAGEO, this component is currently obsolete. Due to its obsolete status, identifying equivalent and substitute parts is essential for design continuity, production planning, and component sourcing in applications requiring 3.3 Ohm resistive elements with comparable electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the RJ1206FRE073R3L is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 3.3 Ohms (exact match required)
• Package / Case: 1206 (3216 Metric) (physical and electrical compatibility)
• Tolerance: ±1% or tighter (±0.5% acceptable as superior specification)
• Power rating: Minimum 0.125W (higher ratings acceptable for thermal margin)
• Termination count: 2 (standard for chip resistors)
• MSL rating: 1 (Unlimited) or equivalent moisture protection

Acceptable Parameter Variations:

• Composition: Thin film preferred; thick film acceptable if all other parameters met
• Temperature coefficient: ±50ppm/°C or lower (tighter tolerance acceptable)
• Operating temperature range: Minimum -55°C ~ 125°C; extended ranges acceptable
• Product status: Active preferred over obsolete for long-term availability

Two substitute parts meet these criteria with enhanced specifications suitable for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

CRCW12063R30FNEA (Vishay Dale) is suitable for applications where automotive qualification is required. This part carries AEC-Q200 certification and ROHS3 compliance, with active product status ensuring long-term availability. The doubled power rating (0.25W vs. 0.125W) provides thermal margin. The thick film composition and higher temperature coefficient (±200ppm/°C) represent trade-offs acceptable in non-precision applications. Physical dimensions are within acceptable tolerance for 1206 package footprints.

RNCF1206DTC3R30 (Stackpole Electronics Inc) is the preferred substitute for precision applications. This part maintains thin film composition matching the original, preserves the ±50ppm/°C temperature coefficient, and offers superior tolerance (±0.5% vs. ±1%). AEC-Q200 certification and ROHS3 compliance are provided. The doubled power rating (0.25W) and extended operating temperature range (-55°C ~ 155°C) exceed original specifications. Physical dimensions are within acceptable tolerance for 1206 package footprints.

Both substitutes are active products with established supply chains, addressing the obsolescence of the original RJ1206FRE073R3L.

Frequently Asked Questions (FAQ)

Q: Can CRCW12063R30FNEA and RNCF1206DTC3R30 be used interchangeably with RJ1206FRE073R3L?

A: Both parts are electrically and mechanically compatible as direct replacements. The 1206 package footprint is identical. Resistance value (3.3 Ohms), tolerance (±1% or tighter), and MSL rating (1) match or exceed original specifications. Selection between the two depends on application requirements: CRCW12063R30FNEA for automotive applications requiring AEC-Q200, RNCF1206DTC3R30 for precision applications requiring lower temperature coefficient.

Q: What is the impact of the higher power rating (0.25W vs. 0.125W) in substitute parts?

A: The increased power rating provides thermal margin and does not negatively impact circuit performance. The physical package dimensions remain 1206 (3216 Metric). PCB footprint compatibility is maintained. Higher power rating indicates improved thermal dissipation capability, beneficial for reliability in applications operating near maximum current limits.

Q: How do composition differences (thin film vs. thick film) affect substitution?

A: RNCF1206DTC3R30 maintains thin film composition identical to the original. CRCW12063R30FNEA uses thick film composition, which typically exhibits higher temperature coefficient (±200ppm/°C vs. ±50ppm/°C). For precision analog circuits or temperature-sensitive applications, RNCF1206DTC3R30 is preferred. For general-purpose applications, CRCW12063R30FNEA is acceptable.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both CRCW12063R30FNEA and RNCF1206DTC3R30 carry ROHS3 compliance certification. The original RJ1206FRE073R3L has REACH Unaffected status. Both substitutes meet current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of AEC-Q200 certification on substitute parts?

A: AEC-Q200 is an automotive industry qualification standard for passive components. Both substitute parts carry this certification, indicating suitability for automotive applications with established reliability and quality standards. This certification is not present on the original obsolete part but is available on both active substitutes.

Q: Are there dimensional concerns when replacing RJ1206FRE073R3L with substitute parts?

A: All three parts use the 1206 (3216 Metric) package with compatible PCB footprints. Dimensional variations are within standard manufacturing tolerances for this package class. Length variations range from 3.05mm to 3.20mm; width is 1.60mm; height variations range from 0.60mm to 0.65mm. These variations do not affect PCB assembly or circuit performance.
