Substitute Part Grouping Explanation

Substitute parts for the RE0805FRE0730K9L are qualified based on the following criteria:

• Identical resistance value: 30.9 kOhms
• Identical package form factor: 0805 (2012 Metric)
• Identical composition: Thick Film
• Identical temperature coefficient: ±50ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Tolerance equal to or tighter than ±1%
• Power rating equal to or greater than 0.125W
• ROHS3 compliance maintained
• MSL rating of 1 (Unlimited)

The substitute parts identified are Panasonic ERJ-PB6 series resistors, which meet all mandatory electrical and mechanical parameters. These substitutes offer enhanced specifications in tolerance (±0.1% and ±0.5%) and power rating (0.25W / 1/4W), with additional automotive AEC-Q200 qualification and pulse withstanding capability.

Parameter Comparison

Engineering Selection Recommendations

Both Panasonic ERJ-PB6 series substitutes are qualified replacements for the RE0805FRE0730K9L based on electrical and mechanical compatibility. Selection between substitute options depends on application requirements:

ERJ-PB6B3092V (±0.1% tolerance) is suitable for applications requiring tighter tolerance control and higher precision circuit performance. This part provides the most stringent tolerance specification among available options.

ERJ-PB6D3092V (±0.5% tolerance) offers a balance between tolerance performance and component availability, with significantly higher inventory levels (5212 pcs vs. 1381 pcs for the ±0.1% variant).

Both substitutes provide doubled power rating capacity (0.25W vs. 0.125W) and automotive AEC-Q200 qualification with pulse withstanding capability, delivering enhanced reliability margins for general-purpose and automotive applications. All candidates maintain Active product status, ROHS3 compliance, and MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PB6B3092V and ERJ-PB6D3092V be used interchangeably with RE0805FRE0730K9L?

A: Yes. Both Panasonic parts are direct electrical and mechanical substitutes. They share identical resistance value (30.9 kOhms), package form factor (0805), composition (thick film), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C). The primary differences are tolerance specification and power rating, both of which are equal to or better than the original part.

Q: What is the difference between ERJ-PB6B3092V and ERJ-PB6D3092V?

A: The primary difference is tolerance specification. ERJ-PB6B3092V offers ±0.1% tolerance, while ERJ-PB6D3092V offers ±0.5% tolerance. Both share identical power rating (0.25W), package dimensions, and automotive AEC-Q200 qualification. Selection depends on circuit tolerance requirements and component availability.

Q: Are the physical dimensions identical between all three parts?

A: The package form factor is identical (0805 / 2012 Metric) for all three parts. Maximum seated height differs slightly: RE0805FRE0730K9L is 0.024" (0.60mm), while both Panasonic substitutes are 0.028" (0.70mm). This 0.004" (0.10mm) difference is within standard PCB assembly tolerances and does not affect mechanical compatibility.

Q: Do the substitute parts carry automotive qualification?

A: Yes. Both ERJ-PB6B3092V and ERJ-PB6D3092V carry AEC-Q200 automotive qualification with pulse withstanding capability. The original RE0805FRE0730K9L does not specify automotive qualification. This makes the Panasonic substitutes suitable for automotive and high-reliability applications.

Q: What is the impact of the higher power rating on circuit design?

A: The substitute parts are rated for 0.25W (1/4W) compared to the original 0.125W (1/8W). This provides additional thermal margin and allows operation at higher power dissipation levels without exceeding component ratings. In circuits designed for the original 0.125W specification, the higher power rating presents no negative impact and improves reliability margins.
