Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE074K64L are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 4.64 kOhms
• Power rating: 0.25W (1/4W)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 1206 (3216 Metric)
• Number of terminations: 2
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variations:

• Tolerance may be improved (tighter specification) from ±1% to ±0.1%
• Temperature coefficient may be improved from ±50ppm/°C to ±25ppm/°C
• Dimensional tolerances within supplier specifications for 1206 package
• Additional certifications (AEC-Q200) are permissible enhancements

All identified substitutes maintain full compatibility with the original part's electrical function and PCB footprint while offering equal or superior performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD074K64L (YAGEO): This substitute offers improved tolerance specification (±0.1% versus ±1%) and superior temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical electrical power rating and operating temperature range. Both components are ROHS3 compliant with unlimited moisture sensitivity rating. Selection is appropriate for applications requiring tighter resistance accuracy without automotive qualification requirements. Higher inventory availability (5043 pieces) supports production continuity.

ERA-8AEB4641V (Panasonic Electronic Components): This substitute provides equivalent tolerance and temperature coefficient improvements as the RT1206BRD074K64L while adding AEC-Q200 automotive qualification. The component maintains full electrical and thermal compatibility with identical power rating and operating temperature range. Selection is appropriate for automotive applications, harsh environment deployments, or supply chain diversification strategies. Highest inventory availability (6105 pieces) ensures supply security.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD074K64L directly replace RT1206FRE074K64L on existing PCBs?

A: Yes. Both components use identical 1206 (3216 Metric) package dimensions and footprint. The RT1206BRD074K64L is a direct mechanical and electrical substitute with improved tolerance and temperature coefficient specifications.

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

A: The RT1206FRE074K64L has ±1% tolerance and ±50ppm/°C temperature coefficient. Both RT1206BRD074K64L and ERA-8AEB4641V improve to ±0.1% tolerance and ±25ppm/°C temperature coefficient. The ERA-8AEB4641V adds AEC-Q200 automotive qualification.

Q: Is the ERA-8AEB4641V suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification indicates enhanced reliability testing and is not restricted to automotive use. The component is fully compatible with general industrial and commercial applications.

Q: Are there dimensional differences between these 1206 packages?

A: Nominal dimensions are 3.10mm × 1.60mm (RT1206 series) and 3.20mm × 1.60mm (ERA-8A series). Both fall within standard 1206 package specifications and share identical PCB footprints. Maximum seated heights are 0.65mm and 0.70mm respectively, which do not affect PCB assembly compatibility.

Q: Do all three parts meet ROHS3 compliance?

A: Yes. RT1206FRE074K64L, RT1206BRD074K64L, and ERA-8AEB4641V are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Which substitute should be selected for cost optimization?

A: Selection depends on application requirements. RT1206BRD074K64L offers improved specifications at lower cost than ERA-8AEB4641V. ERA-8AEB4641V is selected when automotive qualification or enhanced reliability certification is required.
