Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-4223-B-T5 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Resistance value: 422 kOhms
• Tolerance: ±0.1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Allowable Variation:

• Power Rating: Substitute parts may have equal or higher power dissipation ratings (0.125W or greater)
• Height - Seated (Max): Physical height may vary within component mounting tolerances
• Automotive Certification: AEC-Q200 certification is not required for substitution but is present on select alternatives

All identified substitute parts meet or exceed the electrical and mechanical requirements of the primary part while maintaining compatibility with standard 0805 surface-mount assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed are active products with ROHS3 compliance and MSL 1 rating, making them suitable for direct substitution in applications requiring 422 kOhms ±0.1% thin film resistors in 0805 package format.

Primary Selection (RG2012P-4223-B-T5 or ERA-6AEB4223V): For applications requiring automotive-grade components with AEC-Q200 certification, either the Susumu RG2012P-4223-B-T5 or Panasonic ERA-6AEB4223V is appropriate. Both provide identical electrical specifications and automotive qualification. The Panasonic ERA-6AEB4223V offers higher inventory availability (11,982 pcs) compared to the Susumu part (794 pcs).

Alternative Selection (RT0805BRD07422KL): The YAGEO RT0805BRD07422KL provides equivalent electrical performance without automotive certification. This part is suitable for non-automotive applications and offers moderate inventory levels (2,722 pcs).

Higher Power Rating Option (5-2176094-3): The TE Connectivity 5-2176094-3 is rated for 0.25W (1/4W) power dissipation, providing thermal margin above the 0.125W specification of the primary part. This part is suitable for applications where additional power headroom is beneficial and offers the highest inventory availability (1,834 pcs). Physical height is slightly increased at 0.026" (0.65mm) compared to 0.020" (0.50mm) for the primary part; verify clearance in space-constrained layouts.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-2176094-3 with 0.25W rating be used in place of the 0.125W RG2012P-4223-B-T5?

A: Yes. The 5-2176094-3 is a direct electrical substitute with identical resistance, tolerance, temperature coefficient, and operating temperature range. The higher power rating (0.25W vs. 0.125W) provides additional thermal capacity and does not create compatibility issues. The part maintains the same 0805 package footprint and MSL 1 rating. Physical height increases from 0.020" to 0.026"; verify clearance in height-restricted applications.

Q: Are the Panasonic ERA-6AEB4223V and Susumu RG2012P-4223-B-T5 interchangeable?

A: Yes. Both parts are electrically and mechanically identical with 422 kOhms ±0.1% resistance, 0.125W power rating, ±25ppm/°C temperature coefficient, and AEC-Q200 automotive certification. Physical height differs slightly (0.024" vs. 0.020"), but both are within standard 0805 assembly tolerances. The Panasonic part offers significantly higher inventory availability.

Q: Does the YAGEO RT0805BRD07422KL lack automotive certification?

A: The YAGEO RT0805BRD07422KL does not carry AEC-Q200 certification. It is suitable for industrial and consumer applications requiring 422 kOhms ±0.1% thin film resistors in 0805 package. For automotive applications requiring AEC-Q200 qualification, use the Susumu RG2012P-4223-B-T5 or Panasonic ERA-6AEB4223V.

Q: What is the impact of height variation among substitute parts?

A: The primary part (RG2012P-4223-B-T5) has a maximum seated height of 0.020" (0.50mm). Substitute parts range from 0.024" to 0.026" (0.60mm to 0.65mm). These variations are within standard 0805 component tolerances and do not affect electrical performance. Verify clearance in applications with height constraints, such as low-profile assemblies or designs with minimal component-to-component spacing.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All four parts—RG2012P-4223-B-T5, 5-2176094-3, ERA-6AEB4223V, and RT0805BRD07422KL—are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting environmental and reliability standards for industrial and automotive applications.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts share identical 0805 (2012 Metric) package footprints, land patterns, and solder pad configurations. No PCB layout modifications are required for substitution. Verify component height clearance in space-constrained designs before final selection.
