Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-3923-D-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 392 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±0.5% (main part) to ±0.1% (substitutes) — tighter tolerance is acceptable
• Power Rating: 0.125W (main part) to 0.25W (substitutes) — higher power rating is acceptable
• Automotive Rating: AEC-Q200 (main part) to non-rated (substitutes) — automotive-rated substitutes are preferred but non-rated alternatives are functionally compatible

Substitute parts identified below meet the mandatory matching parameters and represent acceptable variations in tolerance and power rating.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Preferred): ERA-6AEB3923V (Panasonic Electronic Components) is the preferred substitute. This part maintains AEC-Q200 automotive qualification matching the original specification, provides improved tolerance (±0.1% versus ±0.5%), and operates within identical temperature parameters. The 0.024" seated height is compatible with standard PCB assembly processes. High inventory availability (8976 pieces) supports production continuity.

Secondary Substitutes: RT0805BRD07392KL (YAGEO) provides equivalent electrical performance with ±0.1% tolerance and 0.125W power rating. While not automotive-rated, it meets all mandatory electrical and mechanical parameters. Inventory availability is adequate (1616 pieces).

Alternative Substitute (Higher Power Rating): 5-2176094-0 (TE Connectivity Passive Product) offers increased power dissipation capability (0.25W versus 0.125W) with improved tolerance (±0.1%). This part is suitable for applications requiring higher thermal margin. The 0.026" seated height remains within standard PCB assembly tolerances. Inventory availability is sufficient (942 pieces).

All substitute parts are ROHS3 compliant, MSL 1 rated, and maintain the -55°C ~ 155°C operating temperature range of the original part.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB3923V replace RG2012P-3923-D-T5 in automotive applications? A: Yes. ERA-6AEB3923V carries AEC-Q200 automotive qualification identical to the original part and meets all electrical and mechanical specifications.

Q: What is the difference between ±0.5% and ±0.1% tolerance? A: Tolerance specifies the maximum deviation from the nominal 392 kOhms resistance value. ±0.5% allows deviation up to ±1.96 kOhms, while ±0.1% limits deviation to ±0.392 kOhms. Tighter tolerance (±0.1%) provides higher precision and is acceptable as a substitute for ±0.5% applications.

Q: Are the height differences between substitute parts significant? A: The main part has a maximum seated height of 0.020" (0.50mm). Substitutes range from 0.024" to 0.026" (0.60mm to 0.65mm). These differences are within standard PCB assembly tolerances and do not affect functionality or placement on standard 0805 footprints.

Q: Can 5-2176094-0 be used if the application requires 0.125W power rating? A: Yes. 5-2176094-0 is rated for 0.25W (1/4W), which exceeds the 0.125W requirement. Higher power rating provides additional thermal margin and is functionally compatible.

Q: Is automotive AEC-Q200 qualification required for all applications? A: AEC-Q200 qualification is required only for automotive applications. For non-automotive applications, RT0805BRD07392KL and 5-2176094-0 are functionally equivalent despite lacking automotive certification.

Q: Are all substitute parts available in Tape & Reel packaging? A: Yes. All identified substitutes are supplied in Tape & Reel (TR) packaging, matching the original part's packaging format for automated assembly compatibility.

Q: What is the impact of ±25ppm/°C temperature coefficient on circuit performance? A: Temperature coefficient specifies resistance change per degree Celsius. All parts in this comparison maintain ±25ppm/°C, ensuring identical thermal stability across the -55°C ~ 155°C operating range.
