Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-224-C-T5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 220 kOhms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±10ppm/°C (exact match required)
• Automotive AEC-Q200 rating (required for automotive applications)
• RoHS3 compliance (required for regulatory compliance)

Allowable Variation Parameters:

• Tolerance: Can be equal to or tighter than ±0.25% (±0.1% or ±0.05% are acceptable upgrades)
• Power rating: Can be equal to or greater than 0.125W (0.26W is acceptable upgrade)
• Operating temperature range: Can be equal to or extended (up to 175°C is acceptable)
• Packaging format: Tape & Reel (TR) is acceptable alternative to standard packaging

All identified substitute parts maintain the 220 kOhms resistance value, 0805 package format, thin film composition, and automotive AEC-Q200 qualification. Substitutes offer improved tolerance specifications and/or higher power ratings while maintaining or exceeding the original operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Susumu RG Series Substitutes (Same Manufacturer):

The RG2012N-224-B-T5, RG2012N-224-W-T5, and RG2012N-224-W-T1 are direct Susumu alternatives maintaining identical mechanical and thermal specifications. All three parts are active products with ROHS3 compliance and AEC-Q200 automotive qualification. The RG2012N-224-B-T5 offers improved tolerance (±0.1%) while maintaining the original 0.125W power rating. The RG2012N-224-W-T5 and RG2012N-224-W-T1 provide the tightest tolerance specification (±0.05%) available within the Susumu RG series, with the primary difference being packaging format (T5 versus T1 tape specifications).

Vishay Dale TNPW Series Substitutes (Cross-Manufacturer):

The TNPW0805220KBYEN and TNPW0805220KBYEA represent cross-manufacturer alternatives from Vishay Dale. These components maintain the 220 kOhms resistance, 0805 package, and AEC-Q200 automotive rating. Both Vishay parts offer enhanced power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C to 175°C versus -55°C to 155°C). The Vishay components include moisture-resistant coating in addition to anti-sulfur protection. Both parts maintain ±0.1% tolerance and ROHS3 compliance.

Selection Criteria:

For applications requiring continued supply of the original specification, the Susumu RG2012N-224-B-T5 provides the most direct replacement with active product status. For applications where improved tolerance is beneficial, the RG2012N-224-W-T5 or RG2012N-224-W-T1 offer ±0.05% tolerance. For applications requiring higher power dissipation capability or extended temperature operation, the Vishay Dale TNPW0805220KBYEN or TNPW0805220KBYEA are suitable alternatives with enhanced specifications.

Frequently Asked Questions (FAQ)

Q: Can the RG2012N-224-B-T5 be used as a direct replacement for the RG2012N-224-C-T5?

A: Yes. The RG2012N-224-B-T5 maintains identical resistance (220 kOhms), package (0805), power rating (0.125W), temperature coefficient (±10ppm/°C), operating temperature range (-55°C to 155°C), and automotive AEC-Q200 qualification. The tolerance is improved from ±0.25% to ±0.1%, which is a compatible upgrade. Both parts are thin film composition with anti-sulfur coating and ROHS3 compliance.

Q: What is the difference between RG2012N-224-W-T5 and RG2012N-224-W-T1?

A: Both parts are identical in electrical specifications: 220 kOhms ±0.05% tolerance, 0.125W power rating, and all other parameters. The difference is in the tape specification format (T5 versus T1), which relates to the reel configuration for automated assembly. Selection between these parts depends on equipment compatibility with the specific tape format.

Q: Can Vishay Dale TNPW0805220KBYEN be substituted for the original RG2012N-224-C-T5?

A: Yes, with the following considerations. The Vishay part maintains the 220 kOhms resistance, 0805 package, thin film composition, ±10ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. The Vishay part offers enhanced specifications: ±0.1% tolerance (tighter than the original ±0.25%), 0.26W power rating (higher than the original 0.125W), and extended operating temperature to 175°C (versus 155°C). The Vishay part includes moisture-resistant coating. All parts are ROHS3 compliant with MSL 1 rating.

Q: Are there any package dimension differences between the Susumu and Vishay substitutes?

A: The package designation is identical (0805 / 2012 Metric) for all parts. The maximum seated height differs slightly: Susumu parts are 0.020" (0.50mm) maximum, while Vishay parts are 0.022" (0.55mm) maximum. This 0.002" difference is within standard PCB assembly tolerances and does not affect interchangeability for standard applications.

Q: Which substitute part should be selected for automotive applications?

A: All identified substitute parts maintain AEC-Q200 automotive qualification, which is the primary requirement for automotive applications. Selection among the substitutes depends on specific circuit requirements: choose RG2012N-224-B-T5 for tolerance improvement while maintaining original specifications, choose RG2012N-224-W-T5 or RG2012N-224-W-T1 for the tightest tolerance (±0.05%), or choose Vishay TNPW0805220KBYEN or TNPW0805220KBYEA for enhanced power rating and extended temperature range.

Q: Is the tolerance improvement from ±0.25% to ±0.1% or ±0.05% significant for circuit operation?

A: Tolerance significance depends on circuit function. In precision analog circuits, measurement systems, or feedback networks, tighter tolerance reduces component-induced error and improves overall circuit accuracy. In general-purpose applications where the 220 kOhms value is non-critical, tolerance improvement provides design margin without affecting circuit function. All substitutes maintain the same temperature coefficient (±10ppm/°C), which is the primary thermal stability parameter.

Q: Can the higher power rating (0.26W) of the Vishay parts cause any issues?

A: No. Higher power rating indicates the component can safely dissipate more power without exceeding temperature limits. If the circuit dissipates 0.125W or less through the resistor, the 0.26W rating provides additional thermal margin and reliability. The higher power rating does not affect electrical performance at lower power levels.

Q: What is the inventory status of these substitute parts?

A: All identified substitute parts are active products with current inventory: RG2012N-224-B-T5 (912 pcs), RG2012N-224-W-T5 (664 pcs), RG2012N-224-W-T1 (757 pcs), TNPW0805220KBYEN (890 pcs), and TNPW0805220KBYEA (801 pcs). The original RG2012N-224-C-T5 is obsolete with 1095 pcs remaining in stock.
