RT0402FRE07649RL Equivalent & Substitute Parts

Part Overview

The RT0402FRE07649RL is a 649 Ohm ±1% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This surface mount device is rated for 0.063W (1/16W) power dissipation with an operating temperature range of -55°C to 155°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the original part becomes unavailable, when design requirements demand tighter tolerance specifications, or when automotive-grade reliability certifications are required for specific applications.

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE07649RL is determined by the following criteria:

Mandatory Parameters (Must Match):

Resistance value: 649 Ohms
Package type: 0402 (1005 Metric)
Composition: Thin Film
Termination count: 2
Packaging format: Tape & Reel (TR)

Compatible Parameters (May Vary):

Tolerance: ±1% or tighter (±0.1%)
Temperature coefficient: Equal to or better than ±50ppm/°C
Operating temperature range: Must encompass -55°C to 155°C
RoHS compliance status
Automotive certifications (AEC-Q200)

All four substitute parts meet the mandatory parameters. Three substitutes (RT0402BRD07649RL, CPF0402B649RE1, ERA-2AEB6490X) offer improved tolerance specifications at ±0.1%. One substitute (RN73C1E649RBTDF) does not carry ROHS3 compliance.

Engineering Selection Recommendations

RT0402BRD07649RL (YAGEO): Direct upgrade from the original part. Maintains YAGEO manufacturer continuity while providing tighter ±0.1% tolerance and improved temperature coefficient (±25ppm/°C). ROHS3 compliant. Suitable for applications requiring enhanced precision without automotive qualification.

CPF0402B649RE1 (TE Connectivity): Cross-manufacturer substitute offering ±0.1% tolerance and ±25ppm/°C temperature coefficient. ROHS3 compliant. Appropriate for designs where manufacturer diversification is acceptable and precision requirements exceed ±1%.

ERA-2AEB6490X (Panasonic): Automotive-grade substitute with AEC-Q200 certification. Provides ±0.1% tolerance and ±25ppm/°C temperature coefficient with ROHS3 compliance. Maximum seated height is 0.016" (0.40mm), which is 0.002" taller than other options. Required for automotive applications or designs with AEC-Q200 mandates.

RN73C1E649RBTDF (TE Connectivity): Offers superior temperature coefficient performance at ±10ppm/°C with ±0.1% tolerance. However, this part is RoHS non-compliant and carries undefined REACH status. Use only in applications where RoHS compliance is not required and where the enhanced temperature stability justifies the compliance trade-off.

Frequently Asked Questions (FAQ)

Q: Can I substitute RT0402FRE07649RL with any of these parts directly on the PCB?

A: Yes, all substitute parts share identical package dimensions (0402/1005 Metric) and footprint requirements. Physical PCB compatibility is assured. However, verify that your design does not require specific RoHS or automotive certifications before selecting a substitute.

Q: What is the difference between ±1% and ±0.1% tolerance?

A: Tolerance defines the acceptable resistance deviation from the nominal 649 Ohm value. ±1% allows deviation of ±6.49 Ohms (643.51 to 654.49 Ohms), while ±0.1% restricts deviation to ±0.649 Ohms (648.35 to 649.65 Ohms). Tighter tolerance is beneficial for precision analog circuits, measurement equipment, and high-accuracy signal conditioning.

Q: Why is the ERA-2AEB6490X taller than other options?

A: The ERA-2AEB6490X has a maximum seated height of 0.016" (0.40mm) compared to 0.014" (0.35mm) for other substitutes. This 0.002" difference may affect PCB assembly clearance in space-constrained designs. Verify board-level height constraints before selecting this part.

Q: Is RN73C1E649RBTDF suitable for my application?

A: RN73C1E649RBTDF is suitable only if your application does not require RoHS compliance. The part offers superior temperature coefficient performance (±10ppm/°C) but carries RoHS non-compliance status and undefined REACH compliance. Confirm regulatory requirements before use.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive electronics qualification standard. ERA-2AEB6490X carries this certification, making it suitable for automotive applications and designs requiring automotive-grade reliability. Non-automotive applications do not require this certification.

Q: Can I mix different substitute parts in the same design?

A: Yes, all substitutes are electrically and mechanically compatible. However, maintain consistency within critical circuit sections where tolerance matching is important. Document any substitutions in design records for traceability.
