RE0805FRE07178KL Equivalent & Substitute Parts

Part Overview

The RE0805FRE07178KL is a 178 kOhms ±1% thick film chip resistor manufactured by YAGEO in 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 MSL Level 1 (Unlimited moisture sensitivity). Substitute parts are identified when equivalent resistance values, package dimensions, and thermal specifications align within acceptable electrical and mechanical tolerances for the 0805 form factor.

Substitute Part Grouping Explanation

Substitute parts for the RE0805FRE07178KL are qualified based on the following criteria:

• Identical resistance value: 178 kOhms
• Identical package format: 0805 (2012 Metric)
• Identical physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Identical composition: Thick Film
• Identical temperature coefficient: ±50ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical RoHS and REACH compliance status
• Equal or superior power rating capability
• Equal or tighter tolerance specifications

The substitute parts identified are Panasonic ERJ-PB series resistors, which maintain all critical electrical and mechanical parameters while offering enhanced specifications in power rating and tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both Panasonic ERJ-PB6 series substitutes maintain full electrical and mechanical compatibility with the RE0805FRE07178KL. The ERJ-PB6B1783V offers ±0.1% tolerance with 0.25W power rating and AEC-Q200 automotive qualification. The ERJ-PB6D1783V provides ±0.5% tolerance with identical 0.25W power rating and AEC-Q200 automotive qualification. Both substitute parts exceed the original specification in power dissipation capability and maintain compliance with ROHS3 and REACH requirements. Selection between substitutes depends on tolerance requirements and automotive application needs.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PB6B1783V and ERJ-PB6D1783V be used interchangeably with RE0805FRE07178KL?

A: Yes. Both Panasonic parts maintain identical resistance values, package dimensions (0805), composition (thick film), temperature coefficients, and operating temperature ranges. The primary differences are tolerance specifications and power ratings, both of which are equal to or superior to the original part.

Q: What is the impact of the height difference between the original and substitute parts?

A: The RE0805FRE07178KL has a maximum seated height of 0.024" (0.60mm), while both Panasonic substitutes have a maximum seated height of 0.028" (0.70mm). This 0.004" (0.10mm) difference must be evaluated for PCB assembly clearance and component placement constraints in your specific application.

Q: Are the Panasonic substitutes suitable for automotive applications?

A: Both ERJ-PB6B1783V and ERJ-PB6D1783V carry AEC-Q200 automotive qualification. The original RE0805FRE07178KL does not specify automotive rating. If automotive qualification is required, the Panasonic substitutes provide this additional certification.

Q: What tolerance should I select between the two Panasonic options?

A: ERJ-PB6B1783V provides ±0.1% tolerance, while ERJ-PB6D1783V provides ±0.5% tolerance. The original part specifies ±1% tolerance. Selection depends on circuit accuracy requirements and cost considerations.

Q: Are all three parts ROHS3 compliant?

A: Yes. The RE0805FRE07178KL, ERJ-PB6B1783V, and ERJ-PB6D1783V are all ROHS3 compliant with MSL Level 1 (Unlimited moisture sensitivity).
