Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-3833-D-T5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 383 kOhms (exact match required)
• Package / Case: 0805 (2012 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 required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variation Parameters:

• Tolerance: May be equal or tighter (±0.5% or better)
• Power Rating: May be equal or higher (0.125W or greater)
• Automotive Rating: May be present or absent (AEC-Q200 optional)

The identified substitute parts meet all mandatory compatibility parameters while offering improvements in tolerance and/or power rating specifications.

Parameter Comparison

Engineering Selection Recommendations

ERA-6AEB3833V (Panasonic Electronic Components)

This part is functionally equivalent to the RG2012P-3833-D-T5 with enhanced tolerance specification (±0.1% versus ±0.5%). Both components maintain identical power rating, package dimensions, and automotive AEC-Q200 certification. The Panasonic ERA-6A series part is active in production with significantly higher inventory availability (22858 units). Height difference is 0.004" (0.10mm), which remains within typical PCB assembly tolerances. This substitute is suitable for applications requiring equivalent or improved precision performance.

4-2176094-9 (TE Connectivity Passive Product)

This part provides a higher power rating (0.25W versus 0.125W) while maintaining the same resistance value and package format. Tolerance is improved to ±0.1%. The TE Connectivity RP73P series part does not carry automotive AEC-Q200 certification. Height difference is 0.006" (0.15mm). This substitute is applicable in non-automotive applications or where increased power dissipation capability is beneficial. The higher power rating provides additional thermal margin in the circuit design.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB3833V replace RG2012P-3833-D-T5 in automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification and are identical in resistance, package, composition, temperature coefficient, and operating temperature range. The ERA-6AEB3833V offers tighter tolerance (±0.1% versus ±0.5%) and maintains the same 0.125W power rating. Height difference of 0.004" (0.10mm) is within standard PCB assembly specifications.

Q: What is the primary difference between ERA-6AEB3833V and 4-2176094-9?

A: The primary difference is power rating and automotive certification. ERA-6AEB3833V is rated 0.125W with AEC-Q200 certification, while 4-2176094-9 is rated 0.25W without automotive certification. Both offer ±0.1% tolerance. Selection depends on application requirements for power dissipation and automotive compliance.

Q: Are all three parts physically interchangeable on a PCB?

A: All three parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Height differences range from 0.020" to 0.026" (0.50mm to 0.65mm), which are within standard PCB assembly tolerances. Physical interchangeability is confirmed for standard reflow soldering processes.

Q: Which substitute part offers the best tolerance specification?

A: Both ERA-6AEB3833V and 4-2176094-9 offer ±0.1% tolerance, which is tighter than the main part's ±0.5% specification. Selection between these two depends on power rating requirements and automotive certification needs.

Q: Can 4-2176094-9 be used in automotive applications?

A: 4-2176094-9 does not carry AEC-Q200 automotive certification. Use in automotive applications requires verification against specific design and qualification requirements. For automotive-qualified alternatives, ERA-6AEB3833V is the appropriate substitute.

Q: What is the impact of the height difference between these parts?

A: Height variations range from 0.020" to 0.026" (0.50mm to 0.65mm). These differences are within standard PCB assembly and reflow soldering tolerances and do not impact electrical performance or mechanical fit in standard 0805 footprints.

Q: Are all parts RoHS3 compliant?

A: Yes. RG2012P-3833-D-T5, ERA-6AEB3833V, and 4-2176094-9 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), confirming compatibility with modern manufacturing and environmental standards.
