Substitute Part Grouping Explanation

Substitute parts for the RGC0805FTC3K92 are qualified based on the following criteria:

• Identical resistance value: 3.92 kOhms
• Identical package / case: 0805 (2012 Metric)
• Identical composition: Thick Film
• Identical temperature coefficient: ±50ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical RoHS compliance: ROHS3 Compliant
• Identical MSL rating: 1 (Unlimited)

Substitute parts may have improved tolerance specifications (tighter than ±1%) and higher power ratings (greater than 0.125W) without affecting compatibility. These enhancements provide design flexibility for applications requiring higher precision or power dissipation margins.

Parameter Comparison

Engineering Selection Recommendations

Both ERJ-PB6B3921V and ERJ-PB6D3921V are direct substitutes for the RGC0805FTC3K92. Selection between these options depends on application requirements:

ERJ-PB6B3921V provides the tightest tolerance specification at ±0.1% and includes AEC-Q200 automotive qualification with pulse withstanding capability. This part is suitable for precision applications requiring enhanced reliability and automotive-grade performance.

ERJ-PB6D3921V offers ±0.5% tolerance with identical AEC-Q200 automotive qualification and pulse withstanding features. This part balances tolerance precision with cost considerations for automotive and industrial applications.

Both substitute parts feature doubled power rating (0.25W versus 0.125W) and slightly increased seated height (0.028" versus 0.024"), which must be verified for PCB layout compatibility. All parts maintain identical resistance value, package dimensions, temperature coefficient, operating temperature range, and environmental compliance ratings.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PB6B3921V or ERJ-PB6D3921V be used as direct replacements for RGC0805FTC3K92?

A: Yes. Both parts share identical resistance value (3.92 kOhms), package type (0805), composition (thick film), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C). All three parts are ROHS3 compliant with MSL rating 1.

Q: What is the difference between the two substitute parts?

A: ERJ-PB6B3921V has ±0.1% tolerance, while ERJ-PB6D3921V has ±0.5% tolerance. Both have identical power rating (0.25W), package dimensions, and AEC-Q200 automotive qualification.

Q: Will the increased seated height of substitute parts affect PCB assembly?

A: Substitute parts have maximum seated height of 0.028" compared to 0.024" for the original part. This 0.004" (0.10mm) difference must be evaluated for PCB layout, solder reflow profile, and component clearance requirements.

Q: Are the substitute parts suitable for automotive applications?

A: Yes. Both ERJ-PB6B3921V and ERJ-PB6D3921V carry AEC-Q200 automotive qualification and pulse withstanding capability, making them suitable for automotive-grade applications.

Q: Can I use a substitute part with higher power rating in a circuit designed for 0.125W?

A: Yes. The substitute parts rated for 0.25W (1/4W) can be used in applications designed for 0.125W (1/8W) without derating concerns. The higher power rating provides additional thermal margin.
