Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-5232-C-T5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 52.3 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (physical and electrical footprint compatibility)
• Composition: Thin Film (electrical performance characteristics)
• Temperature Coefficient: ±10ppm/°C (thermal stability)
• Automotive AEC-Q200 rating (quality and reliability standard)
• RoHS3 compliance (regulatory requirement)

Allowable Variation Parameters:

• Tolerance: Substitute parts with equal or tighter tolerance (±0.25%, ±0.1%, ±0.05%) are functionally compatible
• Power Rating: Substitute parts with equal or higher power rating (0.125W or greater) are compatible
• Operating Temperature Range: Substitute parts with equal or extended upper temperature limit are compatible
• Packaging format: Both cut tape and tape & reel formats are mechanically compatible

All substitute parts listed maintain identical resistance value, package dimensions, composition type, and automotive qualification. Variations in tolerance and power rating represent upgrades that do not compromise circuit functionality.

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The RG2012N-5232-B-T5, RG2012N-5232-W-T1, and RG2012N-5232-W-T5 are direct Susumu alternatives with active product status. These parts maintain identical mechanical footprint, electrical composition, and automotive qualification. The RG2012N-5232-B-T5 and RG2012N-5232-W-T5 offer tighter tolerance specifications (±0.1% and ±0.05% respectively) compared to the original ±0.25%, providing improved circuit accuracy without power rating changes. The RG2012N-5232-W-T1 provides the tightest tolerance (±0.05%) with identical electrical performance characteristics.

Cross-Manufacturer Substitute (Vishay Dale):

The TNPW080552K3BYEA from Vishay Dale represents a cross-manufacturer alternative with active product status. This part maintains the 52.3 kOhms resistance, ±10ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. The TNPW080552K3BYEA provides enhanced power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C), with additional moisture-resistant construction. Tolerance specification is ±0.1%, representing an upgrade from the original ±0.25%.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical package dimensions, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-5232-B-T5 be used as a direct replacement for RG2012N-5232-C-T5?

A: Yes. Both parts share identical resistance (52.3 kOhms), package (0805), power rating (0.125W), composition (thin film), temperature coefficient (±10ppm/°C), and automotive AEC-Q200 qualification. The RG2012N-5232-B-T5 features tighter tolerance (±0.1% versus ±0.25%), which improves circuit accuracy without introducing incompatibility.

Q: What is the difference between RG2012N-5232-W-T1 and RG2012N-5232-W-T5?

A: Both parts are electrically identical with 52.3 kOhms resistance, ±0.05% tolerance, 0.125W power rating, and identical package specifications. The primary difference is packaging format: RG2012N-5232-W-T1 uses tape & reel (T1) format, while RG2012N-5232-W-T5 uses tape & reel (T5) format. Both are mechanically compatible with the original part.

Q: Is TNPW080552K3BYEA compatible with the original RG2012N-5232-C-T5?

A: Yes. The TNPW080552K3BYEA maintains the same 52.3 kOhms resistance, 0805 package, thin film composition, ±10ppm/°C temperature coefficient, and AEC-Q200 automotive rating. The Vishay Dale part provides enhanced specifications: higher power rating (0.26W), extended temperature range (-55°C ~ 175°C), and moisture-resistant construction. These represent functional upgrades with no compatibility issues.

Q: Can I use a substitute part with higher power rating?

A: Yes. The TNPW080552K3BYEA with 0.26W power rating is compatible with circuits designed for the original 0.125W part. Higher power rating provides additional thermal margin and does not compromise circuit operation.

Q: Are all substitute parts available in tape & reel packaging?

A: Yes. All substitute parts listed (RG2012N-5232-B-T5, RG2012N-5232-W-T1, RG2012N-5232-W-T5, and TNPW080552K3BYEA) are supplied in tape & reel format, suitable for automated assembly processes.

Q: Do substitute parts maintain the same physical dimensions?

A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Maximum seated height is 0.020" (0.50mm) for Susumu parts and 0.022" (0.55mm) for the Vishay Dale part, both within standard PCB assembly tolerances.

Q: What is the advantage of selecting a tighter tolerance substitute?

A: Tighter tolerance specifications (±0.1% or ±0.05%) reduce circuit parameter variation and improve overall system accuracy. For precision analog circuits, signal conditioning, or reference applications, tighter tolerance substitutes provide enhanced performance without requiring circuit redesign.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts maintain ROHS3 compliance and are suitable for applications with RoHS regulatory requirements.
