Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNCF0402BTE210R is determined by the following critical parameters:

• Resistance value: 210 Ohms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package format: 0402 (1005 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match or better required)
• Automotive Qualification: AEC-Q200 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The ERA-2AEB2100X qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The power rating difference (0.063W vs 0.1W) does not disqualify substitution when the application circuit operates within the lower power envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the RNCF0402BTE210R and ERA-2AEB2100X maintain active production status and full compliance with ROHS3 and AEC-Q200 automotive standards. Selection between these parts should be based on application power dissipation requirements and supply chain availability. The ERA-2AEB2100X offers higher inventory availability (13,125 units) compared to the RNCF0402BTE210R (794 units). The power rating differential (0.1W vs 0.063W) is not a limiting factor when circuit design ensures operation within the lower power specification of the substitute part.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEB2100X replace RNCF0402BTE210R in all applications?

A: Substitution is valid when the circuit design operates the resistor within the 0.063W power envelope of the ERA-2AEB2100X. If the application requires the full 0.1W power rating, the original RNCF0402BTE210R must be used.

Q: Are the physical dimensions compatible for PCB assembly?

A: Both parts use the 0402 (1005 Metric) package format with identical length and width (0.039" x 0.020"). The height difference (0.014" vs 0.016" maximum seated height) is within standard PCB assembly tolerances and does not affect placement or soldering.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both RNCF0402BTE210R and ERA-2AEB2100X carry AEC-Q200 automotive qualification and are ROHS3 compliant, meeting automotive supply chain requirements.

Q: What is the significance of the ±25ppm/°C temperature coefficient?

A: The temperature coefficient specifies resistance drift over the operating temperature range (-55°C to 155°C). Both parts maintain identical temperature stability characteristics, ensuring equivalent performance across thermal extremes.

Q: Are there any moisture sensitivity concerns?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard dry storage practices apply to both components.
