Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following electrical and mechanical parameters:

Primary Compatibility Criteria:

• Resistance value: 422 kOhms (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W minimum (equal or higher acceptable)
• Composition: Thin film technology
• Operating temperature range: -55°C to 155°C minimum (equal or wider acceptable)
• Tolerance: ±0.25% or tighter (equal or tighter acceptable)

Substitution Categories:

Direct Equivalents maintain all electrical parameters identical to the main part while offering active product status. These parts are pin-compatible and footprint-compatible with no design modifications required.

Upgraded Substitutes offer improved tolerance specifications (±0.1% or ±0.05%) or enhanced temperature coefficients while maintaining all other critical parameters. These parts provide superior performance characteristics within the same physical footprint.

Cross-Manufacturer Alternatives provide equivalent electrical and mechanical specifications from different manufacturers, ensuring supply chain flexibility while maintaining full compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement with Maintained Specifications:

RT0805CRD07422KL (YAGEO) provides electrical equivalence to the RG2012P-4223-C-T5 with identical tolerance (±0.25%) and temperature coefficient (±25ppm/°C). This part maintains active product status and ROHS3 compliance. However, AEC-Q200 automotive certification is not specified for this YAGEO variant.

For Automotive-Qualified Substitution:

RG2012P-4223-B-T5 or RG2012P-4223-W-T5 (Susumu) are recommended for applications requiring maintained AEC-Q200 compliance. Both parts are active products with ROHS3 compliance and anti-sulfur coating. RG2012P-4223-B-T5 offers ±0.1% tolerance, while RG2012P-4223-W-T5 provides superior ±0.05% tolerance. Both maintain the ±25ppm/°C temperature coefficient of the original part.

ERA-6AEB4223V (Panasonic) provides an alternative automotive-qualified option with ±0.1% tolerance, AEC-Q200 rating, and active product status. This part offers high inventory availability (11,982 units) and ROHS3 compliance.

For Enhanced Temperature Stability:

RG2012N-4223-B-T5 or RG2012N-4223-W-T1 (Susumu) offer improved temperature coefficients (±10ppm/°C) compared to the original ±25ppm/°C specification. Both maintain AEC-Q200 compliance and active product status. RG2012N-4223-W-T1 additionally provides ±0.05% tolerance.

RP73D2A422KBTDF (TE Connectivity) offers ±15ppm/°C temperature coefficient with ±0.1% tolerance in active status, though AEC-Q200 certification is not specified.

For Increased Power Dissipation Capability:

5-2176094-3 (TE Connectivity) provides 0.25W power rating (double the original 0.125W) while maintaining 422 kOhms resistance and ±0.1% tolerance. This part is suitable for applications requiring higher power handling within the same footprint, though AEC-Q200 certification is not specified.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with tighter tolerance than the original RG2012P-4223-C-T5?

A: Yes. Parts with ±0.1% or ±0.05% tolerance are electrically compatible and provide superior performance. Tighter tolerance specifications do not create incompatibility; they represent improved accuracy within the same resistance value and package format.

Q: What is the difference between RG2012P and RG2012N series parts?

A: Both series use identical 0805 package format and 422 kOhms resistance. The primary difference is temperature coefficient: RG2012P series specifies ±25ppm/°C while RG2012N series specifies ±10ppm/°C. The RG2012N series provides superior temperature stability for applications sensitive to resistance drift across the -55°C to 155°C operating range.

Q: Is the 5-2176094-3 part a suitable substitute despite its 0.25W power rating?

A: The 5-2176094-3 is electrically and mechanically compatible for direct substitution. The higher 0.25W power rating (versus original 0.125W) does not create incompatibility; it indicates the part can dissipate more power without exceeding temperature limits. Physical dimensions remain identical (0805 package). This part is suitable for applications where the original 0.125W rating was adequate or where increased power handling margin is beneficial.

Q: Why do some substitute parts lack AEC-Q200 certification?

A: AEC-Q200 is an automotive qualification standard. Parts without this certification are not disqualified for general use but may not meet specific automotive supply chain requirements. For non-automotive applications, parts such as RT0805BRD07422KL or RP73D2A422KBTDF provide equivalent electrical performance without automotive qualification overhead.

Q: Can I substitute the RG2012P-4223-C-T5 with ERA-6AEB4223V in an automotive application?

A: Yes. ERA-6AEB4223V maintains AEC-Q200 compliance, identical 0805 package format, 422 kOhms resistance, and -55°C to 155°C operating temperature range. The ±0.1% tolerance is tighter than the original ±0.25%, providing improved accuracy. This part is suitable for direct substitution in automotive applications.

Q: What is the significance of the temperature coefficient difference between ±25ppm/°C and ±10ppm/°C?

A: Temperature coefficient defines how much the resistance value changes per degree Celsius. A ±10ppm/°C coefficient results in smaller resistance drift across temperature extremes compared to ±25ppm/°C. For a 422 kOhm resistor operating across the full -55°C to 155°C range (210°C span), the ±10ppm/°C specification limits drift to approximately 0.89%, while ±25ppm/°C allows approximately 2.21% drift. Selection depends on circuit tolerance requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance, matching the original RG2012P-4223-C-T5 specification. This ensures compatibility with environmental and regulatory requirements across all listed alternatives.

Q: Can physical dimensions vary between substitute parts in the same 0805 package?

A: Slight variations in maximum seated height are specified across different manufacturers. The RG2012P-4223-C-T5 specifies 0.020" (0.50mm) maximum height, while some substitutes specify 0.024" to 0.026" maximum height. These variations remain within 0805 package tolerance and do not affect PCB assembly compatibility or electrical performance. Verify specific height requirements only if board-level clearance constraints exist.
