RJ1206FRE074R3L Equivalent & Substitute Parts

Part Overview

The RJ1206FRE074R3L is a 4.3 Ohm ±1% 0.125W chip resistor in 1206 (3216 Metric) package manufactured by YAGEO. This thin film, moisture-resistant component is currently obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The part operates across -55°C to 125°C with a temperature coefficient of ±50ppm/°C and carries MSL 1 (Unlimited) moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the RJ1206FRE074R3L is determined by the following critical parameters:

• Resistance Value: Must be 4.3 Ohms
• Package Type: Must be 1206 (3216 Metric) for PCB compatibility
• Tolerance: ±1% or better (tighter tolerance acceptable)
• Power Rating: Minimum 0.125W; higher ratings acceptable for thermal margin
• Moisture Sensitivity: MSL 1 or equivalent
• Operating Temperature Range: Must cover -55°C to 125°C minimum

Two substitute parts meet these criteria with enhanced specifications:

CRCW12064R30FNEA (Vishay Dale) provides higher power rating (0.25W) with identical resistance and tolerance, though with thicker film composition and automotive AEC-Q200 qualification.

RNCF1206DTC4R30 (Stackpole Electronics Inc) offers superior tolerance (±0.5%), higher power rating (0.25W), thin film composition matching the original, and automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

RNCF1206DTC4R30 is the preferred substitute when component specifications allow. This part maintains thin film composition and ±50ppm/°C temperature coefficient identical to the original, while providing superior tolerance (±0.5%), doubled power rating (0.25W), extended temperature range (-55°C to 155°C), and active product status with ROHS3 compliance and AEC-Q200 automotive qualification.

CRCW12064R30FNEA serves as an alternative when automotive qualification is required or when thin film composition is not critical. This part provides identical resistance and tolerance with doubled power rating and extended temperature range, though with thicker film composition and higher temperature coefficient (±200ppm/°C). Active product status and ROHS3 compliance are confirmed.

Both substitutes are pin-compatible and footprint-compatible with the original RJ1206FRE074R3L, with negligible dimensional variations within standard PCB assembly tolerances.

Frequently Asked Questions (FAQ)

Q: Can CRCW12064R30FNEA directly replace RJ1206FRE074R3L?

A: Yes. Both parts share 4.3 Ohm resistance, ±1% tolerance, 1206 package, and MSL 1 rating. The CRCW part provides higher power rating (0.25W vs 0.125W) and extended temperature range (-55°C to 155°C vs -55°C to 125°C). Thick film vs thin film composition may affect frequency response in high-frequency applications.

Q: Can RNCF1206DTC4R30 directly replace RJ1206FRE074R3L?

A: Yes. Both parts share thin film composition, ±50ppm/°C temperature coefficient, 1206 package, and MSL 1 rating. RNCF1206DTC4R30 provides superior tolerance (±0.5% vs ±1%), higher power rating (0.25W vs 0.125W), and extended temperature range (-55°C to 155°C vs -55°C to 125°C).

Q: What are the dimensional differences between these parts?

A: All three parts use 1206 (3216 Metric) package. Seated heights vary slightly: RJ1206FRE074R3L at 0.65mm maximum, CRCW12064R30FNEA at 0.60mm maximum, and RNCF1206DTC4R30 at 0.65mm maximum. Length and width dimensions are within standard 1206 tolerances across all three parts.

Q: Are both substitutes available in the same packaging format?

A: Yes. CRCW12064R30FNEA and RNCF1206DTC4R30 are both supplied in Tape & Reel (TR) packaging, matching the original RJ1206FRE074R3L format for automated assembly compatibility.

Q: Which substitute is better for precision applications?

A: RNCF1206DTC4R30 offers superior tolerance (±0.5%) and matching temperature coefficient (±50ppm/°C) compared to the original ±1% tolerance. CRCW12064R30FNEA maintains ±1% tolerance but with higher temperature coefficient (±200ppm/°C).

Q: Do both substitutes meet automotive standards?

A: Yes. Both CRCW12064R30FNEA and RNCF1206DTC4R30 carry AEC-Q200 automotive qualification and ROHS3 compliance, exceeding the original part's specifications.
