Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0797R6L is determined by the following mandatory parameters:

• Resistance value: 97.6 Ohms (exact match required)
• Package type: 0402 (1005 Metric) (exact match required)
• Power rating: 0.063W minimum (equal or higher acceptable)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C to 155°C minimum (equal or wider acceptable)
• RoHS3 compliance (required)
• MSL rating: 1 (Unlimited) (equal or better acceptable)

All identified substitute parts meet these mandatory criteria. Enhanced tolerance (±0.1% vs ±1%), improved temperature coefficient, and automotive certification (AEC-Q200) represent upgrades that do not compromise compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the RT0402FRE0797R6L. Selection criteria are based on product status, compliance certifications, and application requirements:

CPF0402B97R6E1 (TE Connectivity Passive Product) provides enhanced tolerance (±0.1%) and improved temperature coefficient (±25ppm/°C) with active product status and ROHS3 compliance. This part is suitable for general industrial applications requiring tighter tolerance specifications.

ERA-2AEB97R6X (Panasonic Electronic Components) offers automotive-grade qualification under AEC-Q200 standard with ±0.1% tolerance and ±25ppm/°C temperature coefficient. This part is specified for automotive and mission-critical applications where AEC-Q200 certification is required. Maximum seated height is 0.016" (0.40mm), which may require PCB layout verification in space-constrained designs.

RN73C1E97R6BTDF (TE Connectivity Passive Product) delivers the lowest temperature coefficient (±10ppm/°C) with ±0.1% tolerance and active product status. This part is optimal for precision analog circuits and applications requiring superior temperature stability. REACH status is listed as Vendor Undefined.

Frequently Asked Questions (FAQ)

Q: Can RT0402FRE0797R6L be directly replaced with any of these substitute parts?

A: Yes. All substitute parts share identical resistance value (97.6 Ohms), package type (0402), power rating (0.063W), composition (Thin Film), operating temperature range (-55°C to 155°C), and RoHS3 compliance. Direct PCB substitution is mechanically and electrically compatible.

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

A: Tolerance specifies the maximum deviation from the nominal resistance value. The RT0402FRE0797R6L allows ±1% deviation (97.6 ± 0.976 Ohms), while substitute parts with ±0.1% tolerance allow only ±0.0976 Ohms deviation. Enhanced tolerance improves circuit accuracy in precision applications.

Q: Why does ERA-2AEB97R6X have a different maximum seated height?

A: ERA-2AEB97R6X has a maximum seated height of 0.016" (0.40mm) compared to 0.014" (0.35mm) for other parts. This 0.002" difference may affect PCB assembly clearance in designs with tight vertical constraints. Verify PCB layout and component placement before substitution.

Q: What is AEC-Q200 certification?

A: AEC-Q200 is an automotive industry standard qualification for passive components. ERA-2AEB97R6X meets this certification, making it suitable for automotive applications where supplier qualification and reliability standards are mandated.

Q: Which substitute part offers the best temperature stability?

A: RN73C1E97R6BTDF provides the lowest temperature coefficient at ±10ppm/°C, compared to ±25ppm/°C for CPF0402B97R6E1 and ERA-2AEB97R6X, and ±50ppm/°C for the original RT0402FRE0797R6L. Lower temperature coefficient indicates superior resistance stability across the operating temperature range.

Q: Are all parts RoHS3 compliant?

A: Yes. RT0402FRE0797R6L and all substitute parts (CPF0402B97R6E1, ERA-2AEB97R6X, RN73C1E97R6BTDF) are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.
