RJ1206FRE073RL Equivalent & Substitute Parts

Part Overview

The RJ1206FRE073RL is a 3 Ohm ±1% 0.125W (1/8W) chip resistor in 1206 (3216 Metric) package manufactured by YAGEO. This thin film, moisture-resistant component operates across -55°C to 125°C with a temperature coefficient of ±50ppm/°C. The part is currently obsolete, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for new designs or production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

• Resistance Value: Must be 3 Ohms
• Tolerance: ±1% or tighter (±0.5% acceptable)
• Package: 1206 (3216 Metric) form factor
• Power Rating: Minimum 0.125W; higher ratings (0.25W) are acceptable as they provide thermal margin
• Operating Temperature Range: Must encompass or exceed -55°C to 125°C
• Moisture Sensitivity: MSL 1 or equivalent

The identified substitutes meet these criteria while offering improved product status (Active vs. Obsolete) and enhanced specifications in certain cases.

Parameter Comparison

Engineering Selection Recommendations

RT1206FRE073RL is the direct upgrade path within the YAGEO RJ/RT series. It maintains thin film composition and ±50ppm/°C temperature coefficient while increasing power rating to 0.25W and extending operating temperature to 155°C. Product status is Active with ROHS3 compliance.

CRCW12063R00FNEA (Vishay Dale) provides an alternative with AEC-Q200 automotive qualification. The thick film composition results in a higher temperature coefficient (±200ppm/°C) compared to the original thin film design. This part is suitable for applications where automotive-grade reliability is required.

RNCF1206DTC3R00 (Stackpole Electronics Inc) offers the tightest tolerance specification at ±0.5% with thin film composition, ±50ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. This part is appropriate for precision applications requiring enhanced accuracy and automotive-grade performance.

All three substitutes are in Active product status with current inventory availability and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can RT1206FRE073RL replace RJ1206FRE073RL in existing designs?

A: Yes. Both parts share identical resistance (3 Ohms), tolerance (±1%), package (1206), and temperature coefficient (±50ppm/°C). The RT variant provides higher power rating (0.25W vs. 0.125W) and extended operating temperature range (-55°C to 155°C vs. -55°C to 125°C), making it a direct functional upgrade.

Q: What is the difference between thin film and thick film compositions?

A: Thin film resistors (RJ, RT, RNCF series) exhibit lower temperature coefficients (±50ppm/°C) and tighter tolerances, suitable for precision applications. Thick film resistors (CRCW series) have higher temperature coefficients (±200ppm/°C) but offer robust automotive qualification. Selection depends on application accuracy requirements.

Q: Are the substitute parts mechanically compatible with the original footprint?

A: All substitute parts use the 1206 (3216 Metric) package. Physical dimensions are equivalent within manufacturing tolerances, ensuring PCB footprint compatibility. Minor dimensional variations (e.g., CRCW at 3.20mm L vs. RJ at 3.10mm L) remain within standard 1206 package specifications.

Q: Which substitute is recommended for automotive applications?

A: Both CRCW12063R00FNEA and RNCF1206DTC3R00 carry AEC-Q200 automotive qualification. RNCF1206DTC3R00 is preferred if precision tolerance (±0.5%) and thin film characteristics are required. CRCW12063R00FNEA is suitable if thick film composition is acceptable.

Q: What is the inventory status of these substitutes?

A: RT1206FRE073RL: 5879 Pcs. CRCW12063R00FNEA: 1067 Pcs. RNCF1206DTC3R00: 660 Pcs. All are available as new original stock in Tape & Reel packaging.
