Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE073K48L are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 3.48 kOhms
• Power rating: 0.25W (1/4W)
• Operating temperature range: -55°C ~ 155°C
• Composition: Thin Film

Mechanical Parameters (Must Match):

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

Allowable Variations:

• Tolerance may be tighter (±0.1% acceptable for ±1% requirement)
• Temperature coefficient may be lower (±25ppm/°C acceptable for ±50ppm/°C)
• Additional certifications (AEC-Q200) do not disqualify substitution
• Physical dimensions within standard 1206 tolerance envelope

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD073K48L (YAGEO): This part provides improved tolerance specification (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical electrical power rating, package format, and compliance certifications. Selection is appropriate for applications requiring tighter resistance accuracy without automotive qualification requirements.

ERA-8AEB3481V (Panasonic Electronic Components): This part offers the same tolerance and temperature coefficient improvements as RT1206BRD073K48L with the addition of AEC-Q200 automotive qualification. Selection is appropriate for automotive applications or systems requiring automotive-grade component reliability. Physical dimensions are within standard 1206 envelope tolerance.

Both substitute parts maintain full compatibility with the original RT1206FRE073K48L in terms of electrical performance, thermal operating range, and mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD073K48L replace RT1206FRE073K48L in any application?

A: Yes. RT1206BRD073K48L is electrically and mechanically compatible. The tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) represent performance improvements. No design modifications are required.

Q: What is the difference between RT1206BRD073K48L and ERA-8AEB3481V?

A: Both parts have identical electrical specifications (3.48 kOhms ±0.1%, 0.25W, ±25ppm/°C). ERA-8AEB3481V includes AEC-Q200 automotive qualification; RT1206BRD073K48L does not. Physical dimensions are within standard 1206 tolerance envelope for both parts.

Q: Is ERA-8AEB3481V suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification is a superset of standard industrial reliability requirements. ERA-8AEB3481V can be used in any application where RT1206FRE073K48L is specified.

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

A: Yes. All three parts use the 1206 (3216 Metric) package format with identical termination count (2). Physical dimensions are within standard tolerance envelope for this package class.

Q: Can I use these parts interchangeably on the same assembly?

A: Yes. All three parts meet the same electrical and mechanical requirements for the 1206 package format. No PCB redesign or assembly process changes are required.
