RJ0805FRE078R2L Equivalent & Substitute Parts

Part Overview

The RJ0805FRE078R2L is an 8.2 Ohms ±1% thin film chip resistor in 0805 (2012 Metric) package rated at 0.1W (1/10W) power dissipation. Manufactured by YAGEO, this component is classified as obsolete. Due to its obsolete status and limited ongoing availability, equivalent and substitute parts from active product lines are necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

• Resistance Value: Must be 8.2 Ohms
• Package / Case: Must be 0805 (2012 Metric)
• Composition: Must be Thin Film
• Tolerance: Must be ±1% or tighter (lower tolerance values are acceptable upgrades)
• Power Rating: Must be ≥0.1W (higher power ratings are acceptable)
• Operating Temperature Range: Must encompass or exceed -55°C ~ 125°C
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

Substitute parts are grouped into two categories:

Category 1: Direct Upgrades (Active Status) Parts that meet or exceed all key parameters while maintaining the same package and composition. These parts offer improved specifications (tighter tolerance, higher power rating, or extended temperature range) and active product status.

Category 2: Manufacturer-Recommended Alternatives (Active Status) Parts that meet all key parameters with enhanced features (automotive qualification, higher power rating) and active product status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Tolerance Requirement)

RT0805FRE078R2L is the primary substitute for RJ0805FRE078R2L. Both maintain ±1% tolerance and 0805 package compatibility. RT0805FRE078R2L offers active product status, ROHS3 compliance, extended operating temperature range (-55°C ~ 155°C), and increased power rating (0.125W vs 0.1W). This part is recommended for new designs and production continuity.

For Enhanced Tolerance Applications

RT0805CRE078R2L and RT0805DRE078R2L provide tighter tolerance specifications (±0.25% and ±0.5% respectively) while maintaining the same package and composition. Both are active products with ROHS3 compliance and extended temperature range. These parts are suitable for applications requiring improved tolerance performance.

For Precision and Extended Power Dissipation

CPF0805B8R2E1 (TE Connectivity) offers ±0.1% tolerance with improved temperature coefficient (±25ppm/°C vs ±50ppm/°C) and extended operating temperature range. Power rating matches the original specification at 0.1W. This part is suitable for precision measurement and signal conditioning applications.

For Automotive and High-Reliability Applications

RNCF0805BTC8R20 and RNCF0805DTC8R20 (Stackpole Electronics) are AEC-Q200 qualified automotive-grade resistors with active product status and ROHS3 compliance. Both offer increased power rating (0.25W) and extended temperature range. RNCF0805BTC8R20 provides ±0.1% tolerance, while RNCF0805DTC8R20 provides ±0.5% tolerance. These parts are suitable for automotive and mission-critical applications.

Frequently Asked Questions (FAQ)

Q: Can RT0805FRE078R2L directly replace RJ0805FRE078R2L?

A: Yes. Both parts share identical resistance (8.2 Ohms), tolerance (±1%), package (0805), and composition (thin film). RT0805FRE078R2L is an active product with improved specifications including higher power rating (0.125W vs 0.1W) and extended operating temperature range (-55°C ~ 155°C vs -55°C ~ 125°C).

Q: What is the difference between the YAGEO RT series substitutes?

A: The RT series substitutes differ in tolerance specification. RT0805CRE078R2L offers ±0.25% tolerance, RT0805DRE078R2L offers ±0.5% tolerance, and RT0805FRE078R2L offers ±1% tolerance. All three maintain identical resistance, package, power rating (0.125W), and operating temperature range (-55°C ~ 155°C).

Q: Are the Stackpole RNCF parts suitable for non-automotive applications?

A: Yes. RNCF0805BTC8R20 and RNCF0805DTC8R20 are AEC-Q200 qualified but can be used in non-automotive applications. They offer superior specifications including higher power rating (0.25W), extended temperature range, and active product status with ROHS3 compliance.

Q: What is the advantage of CPF0805B8R2E1 over other substitutes?

A: CPF0805B8R2E1 provides the tightest tolerance (±0.1%) and lowest temperature coefficient (±25ppm/°C vs ±50ppm/°C for other parts). It maintains the original 0.1W power rating and is suitable for precision applications requiring superior stability and accuracy.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant and active products. The original RJ0805FRE078R2L is obsolete with unspecified RoHS status.

Q: Can I use a higher power-rated substitute in place of the original part?

A: Yes. Higher power-rated substitutes (0.125W or 0.25W) are electrically compatible and can be used in applications designed for 0.1W resistors. The physical dimensions remain identical (0805 package), and higher power rating provides additional thermal margin.
