Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07249KL is determined by strict adherence to the following parameters:

• Resistance Value: Must be 249 kOhms (exact match)
• Package Format: Must be 1206 (3216 Metric) to ensure PCB footprint compatibility
• Power Rating: Must be 0.25W minimum
• Composition: Thin film technology required for performance consistency
• Operating Temperature Range: Must support -55°C to 155°C minimum
• RoHS Compliance: ROHS3 Compliant status required
• Moisture Sensitivity: MSL 1 (Unlimited) acceptable

All three substitute parts listed meet these core substitution criteria. Tolerance and temperature coefficient variations represent performance enhancements rather than compatibility restrictions, allowing direct substitution in applications where the original specification is met or exceeded.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07249KL (YAGEO): Direct upgrade within the same manufacturer's product line. Offers improved tolerance (±0.1% vs ±1%) and reduced temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical package, power rating, and operating temperature specifications. Suitable for applications requiring enhanced precision without automotive qualification requirements.

ERA-8AEB2493V (Panasonic Electronic Components): Provides AEC-Q200 automotive qualification with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Recommended for automotive and harsh environment applications where component reliability certification is mandated. Maintains full compatibility with the original 1206 package footprint and electrical specifications.

RG3216P-2493-B-T5 (Susumi): Combines AEC-Q200 automotive qualification with anti-sulfur protection and ±0.1% tolerance. Lowest profile option (0.020" seated height vs 0.026" for main part) with enhanced environmental resistance. Suitable for automotive applications in corrosive environments or where space constraints favor reduced component height.

All three substitutes are Active products with confirmed inventory availability and full RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07249KL replace RT1206FRE07249KL directly on the PCB?

A: Yes. Both components share identical 1206 (3216 Metric) package dimensions, footprint, and electrical ratings (249 kOhms, 0.25W, -55°C to 155°C). The RT1206BRD07249KL represents a performance upgrade with tighter tolerance and lower temperature coefficient.

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

A: RT1206BRD07249KL is a standard precision upgrade from YAGEO. ERA-8AEB2493V and RG3216P-2493-B-T5 both include AEC-Q200 automotive qualification. RG3216P-2493-B-T5 additionally features anti-sulfur protection and a lower profile (0.020" vs 0.026" seated height).

Q: Are the substitute parts suitable for automotive applications?

A: RT1206BRD07249KL is not automotive-qualified. ERA-8AEB2493V and RG3216P-2493-B-T5 both carry AEC-Q200 certification and are suitable for automotive use.

Q: Will the substitute parts fit the same PCB footprint?

A: Yes. All substitute parts use the 1206 (3216 Metric) package. Physical dimensions are compatible with the original RT1206FRE07249KL footprint. Minor dimensional variations (ERA-8AEB2493V and RG3216P-2493-B-T5 are 0.126" L vs 0.122" L for the main part) do not affect PCB placement compatibility.

Q: What does ±0.1% tolerance mean compared to ±1%?

A: ±0.1% tolerance provides tighter resistance value control. For a 249 kOhms resistor, ±1% allows variation of ±2.49 kOhms, while ±0.1% limits variation to ±0.249 kOhms. Substitute parts with ±0.1% are suitable for precision analog circuits and measurement applications.

Q: Are all parts RoHS3 compliant?

A: Yes. The main part and all three substitutes are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.
