Substitute Part Grouping Explanation

Substitute parts for the RE0805FRE07249KL are qualified based on the following criteria:

• Identical resistance value: 249 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
• Identical RoHS3 compliance status
• Identical MSL rating: 1 (Unlimited)

Substitute parts may differ in tolerance specification and power rating, provided these parameters meet or exceed the requirements of the original part. The identified substitutes are manufactured by Panasonic Electronic Components under the ERJ-PB6 series and maintain full electrical and mechanical compatibility with the RE0805FRE07249KL.

Parameter Comparison

Engineering Selection Recommendations

Both ERJ-PB6B2493V and ERJ-PB6D2493V are valid substitutes for the RE0805FRE07249KL. Selection between these options depends on application requirements:

ERJ-PB6B2493V provides tighter tolerance specification (±0.1%) compared to the original part (±1%), with increased power dissipation capability (0.25W vs. 0.125W) and AEC-Q200 automotive qualification. This part is suitable for applications requiring enhanced precision and automotive-grade reliability.

ERJ-PB6D2493V offers intermediate tolerance (±0.5%) with equivalent power rating increase (0.25W) and AEC-Q200 automotive qualification. This part balances tolerance improvement with cost considerations while maintaining automotive-grade performance standards.

Both substitutes maintain full compliance with RoHS3 and REACH requirements, identical operating temperature ranges, and MSL ratings. All three parts are actively produced and available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PB6B2493V and ERJ-PB6D2493V be used interchangeably with RE0805FRE07249KL?

A: Yes. Both Panasonic parts maintain identical resistance value, package form factor, composition, temperature coefficient, and operating temperature range. The primary differences are tolerance specification and power rating, both of which are improved in the substitute parts.

Q: What is the significance of the tighter tolerance in ERJ-PB6B2493V?

A: ERJ-PB6B2493V specifies ±0.1% tolerance compared to ±1% in the original part. This tighter tolerance reduces resistance variation across the production batch and is applicable to circuits requiring higher precision in resistive element values.

Q: Does the increased power rating in substitute parts affect circuit performance?

A: No. The increased power rating (0.25W vs. 0.125W) in both substitute parts provides additional thermal margin and does not alter electrical performance. The component will operate identically in circuits designed for the original 0.125W specification.

Q: Are the substitute parts suitable for automotive applications?

A: Both ERJ-PB6B2493V and ERJ-PB6D2493V carry AEC-Q200 automotive qualification. The original RE0805FRE07249KL does not specify this rating. If automotive qualification is required, either Panasonic substitute is appropriate.

Q: What is the physical size difference between the original and substitute parts?

A: All three parts use identical 0805 (2012 Metric) package dimensions (0.079" L x 0.049" W). Maximum seated height differs slightly: RE0805FRE07249KL at 0.024" (0.60mm) versus ERJ-PB6 series at 0.028" (0.70mm). This difference is within standard PCB assembly tolerances and does not affect placement or functionality.

Q: Are all parts RoHS3 compliant?

A: Yes. RE0805FRE07249KL, ERJ-PB6B2493V, and ERJ-PB6D2493V are all ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity).
