RE0805FRE0742K2L Equivalent & Substitute Parts

Part Overview

The RE0805FRE0742K2L is a 42.2 kOhms ±1% thick film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. 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 operating ranges are maintained while allowing variations in tolerance, power rating, and composition characteristics within acceptable engineering parameters.

Substitute Part Grouping Explanation

Substitute parts for the RE0805FRE0742K2L are qualified based on the following criteria:

• Identical resistance value: 42.2 kOhms
• Identical package: 0805 (2012 Metric)
• Identical composition: Thick Film
• Identical temperature coefficient: ±50ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical RoHS and MSL compliance

Allowable variations in substitute parts include:

• Tolerance: May be tighter (±0.1%, ±0.5%) than the original ±1%
• Power rating: May be equal or higher (0.25W/1/4W acceptable for 0.125W requirement)
• Additional certifications: AEC-Q200 automotive qualification is permissible

Parameter Comparison

Engineering Selection Recommendations

Both Panasonic ERJ-PB6 series substitutes maintain full electrical and mechanical compatibility with the RE0805FRE0742K2L. Selection between substitute options depends on application requirements:

ERJ-PB6B4222V offers the tightest tolerance specification at ±0.1%, suitable for precision circuit applications requiring enhanced accuracy over the original ±1% tolerance.

ERJ-PB6D4222V provides ±0.5% tolerance with AEC-Q200 automotive qualification, appropriate for automotive and industrial applications requiring automotive-grade reliability standards.

Both substitutes feature higher power ratings (0.25W vs. 0.125W), providing additional thermal margin in applications where the original part operates near maximum power dissipation limits. All three parts maintain identical package footprint, thermal characteristics, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PB6B4222V and ERJ-PB6D4222V be used interchangeably with RE0805FRE0742K2L?

A: Yes. Both Panasonic parts maintain identical resistance, package dimensions, operating temperature range, and thermal coefficient. The tighter tolerances (±0.1% and ±0.5% respectively) are compatible with circuits designed for ±1% tolerance. Higher power ratings provide additional design margin.

Q: What is the difference between ERJ-PB6B4222V and ERJ-PB6D4222V?

A: The primary difference is tolerance specification. ERJ-PB6B4222V is rated ±0.1%, while ERJ-PB6D4222V is rated ±0.5%. Both include AEC-Q200 automotive certification and identical 0.25W power rating. Selection depends on circuit tolerance requirements.

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

A: Yes. All three parts use the 0805 (2012 Metric) package with identical length (0.079"), width (0.049"), and compatible maximum seated heights (0.024" to 0.028"). PCB footprints are interchangeable.

Q: Do the substitute parts require different handling or storage procedures?

A: No. All three parts share MSL Level 1 (Unlimited) rating, indicating identical moisture sensitivity and storage requirements. Standard SMD component handling procedures apply uniformly.

Q: Can these parts be used in automotive applications?

A: The RE0805FRE0742K2L has no specified automotive certification. The Panasonic substitutes (ERJ-PB6B4222V and ERJ-PB6D4222V) carry AEC-Q200 automotive qualification, making them suitable for automotive circuit applications where such certification is required.
