RE0805FRE07120KL Equivalent & Substitute Parts

Part Overview

The RE0805FRE07120KL is a 120 kOhms ±1% thick film chip resistor manufactured by YAGEO in the 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation with an operating temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when they maintain the same resistance value, package format, and core electrical specifications while potentially offering enhanced performance characteristics such as improved tolerance, higher power rating, or automotive-grade qualification.

Substitute Part Grouping Explanation

Substitute parts for the RE0805FRE07120KL are qualified based on the following criteria:

Core Compatibility Requirements:

• Resistance value: 120 kOhms (exact match)
• Package format: 0805 (2012 Metric) (exact match)
• Composition: Thick Film (exact match)
• Temperature Coefficient: ±50ppm/°C (exact match)
• Operating Temperature Range: -55°C ~ 155°C (exact match)
• RoHS Status: ROHS3 Compliant (exact match)

Allowable Parameter Variations:

• Tolerance: May be equal to or tighter than ±1%
• Power Rating: May be equal to or greater than 0.125W (1/8W)
• Moisture Sensitivity Level: May be equal to or lower than MSL 1

The identified substitute parts (ERJ-PB6B1203V and ERJ-PB6D1203V) from Panasonic Electronic Components meet all core compatibility requirements while offering enhanced power ratings (0.25W / 1/4W) and automotive-grade AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

Both Panasonic ERJ-PB6 series substitutes maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the original RE0805FRE07120KL.

ERJ-PB6B1203V provides the tightest tolerance specification at ±0.1% with AEC-Q200 automotive qualification and pulse withstanding capability. This variant is suitable for applications requiring enhanced precision and automotive-grade reliability.

ERJ-PB6D1203V offers ±0.5% tolerance with identical AEC-Q200 automotive qualification and pulse withstanding features. This variant provides a balance between tolerance performance and cost considerations while maintaining automotive-grade specifications.

Both substitutes feature a maximum seated height of 0.028" (0.70mm) compared to the original 0.024" (0.60mm). This 0.004" (0.10mm) height difference must be evaluated for PCB layout clearance in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PB6B1203V and ERJ-PB6D1203V be used interchangeably with RE0805FRE07120KL?

A: Both Panasonic parts are electrically compatible substitutes. They maintain the same 120 kOhms resistance, 0805 package format, ±50ppm/°C temperature coefficient, and -55°C to 155°C operating range. The primary differences are tolerance (±0.1% and ±0.5% respectively versus ±1%), power rating (0.25W versus 0.125W), and automotive AEC-Q200 qualification. Physical height increases from 0.024" to 0.028" must be verified for PCB clearance.

Q: What is the significance of the tighter tolerance in ERJ-PB6B1203V?

A: The ±0.1% tolerance in ERJ-PB6B1203V provides significantly tighter resistance accuracy compared to the ±1% specification of RE0805FRE07120KL. This enhanced precision is beneficial in applications where circuit performance depends on accurate resistor values, such as precision analog circuits, sensor interfaces, or calibration networks.

Q: Are the Panasonic substitutes suitable for automotive applications?

A: Yes. Both ERJ-PB6B1203V and ERJ-PB6D1203V carry AEC-Q200 automotive qualification and pulse withstanding features, making them suitable for automotive-grade circuit designs. The original RE0805FRE07120KL does not specify automotive qualification.

Q: Does the increased power rating of the substitutes affect circuit performance?

A: The increased power rating from 0.125W to 0.25W does not negatively affect circuit performance. Higher power rating indicates greater thermal capability and margin. The substitutes will operate cooler under identical current conditions, potentially improving long-term reliability.

Q: What is the impact of the 0.004" height difference?

A: The Panasonic substitutes have a maximum seated height of 0.028" compared to 0.024" for the original part. This 0.004" (0.10mm) increase must be verified against PCB layout constraints, particularly in applications with limited vertical clearance or where components are mounted near other tall components or connectors.

Q: Are all three parts ROHS3 compliant?

A: Yes. RE0805FRE07120KL, ERJ-PB6B1203V, and ERJ-PB6D1203V are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, ensuring regulatory compliance and unlimited shelf life under standard storage conditions.
