Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-4532-C-T5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 45.3 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Automotive AEC-Q200 rating (required for automotive applications)
• Anti-sulfur construction (required for reliability)
• RoHS3 compliance (required for regulatory conformance)

Allowable Variation Parameters:

• Tolerance: May be equal to or tighter (lower) than ±0.25%
• Power rating: May be equal to or higher than 0.125W
• Operating temperature range: May be equal to or wider than -55°C ~ 155°C
• Temperature coefficient: Must remain ±10ppm/°C

The substitute parts listed below meet all mandatory compatibility requirements while offering enhanced tolerance specifications or increased power ratings, making them suitable direct replacements in applications where the original part is no longer available.

Parameter Comparison

Engineering Selection Recommendations

RG2012N-4532-B-T5 (Susumu)

This part is an active Susumu component offering tighter tolerance (±0.1%) compared to the original ±0.25% specification. All electrical and mechanical parameters remain identical to the RG2012N-4532-C-T5, including power rating, package dimensions, and operating temperature range. AEC-Q200 automotive qualification and anti-sulfur construction are maintained. This substitute provides improved tolerance performance without requiring any circuit redesign or layout modifications.

RG2012N-4532-W-T1 and RG2012N-4532-W-T5 (Susumu)

Both parts offer the highest tolerance specification (±0.05%) within the Susumu RG series. Electrical and mechanical parameters are identical to the original part. The primary difference between these two variants is packaging format (T1 versus T5 tape specifications). Both are active products with full AEC-Q200 compliance and anti-sulfur construction. These substitutes are suitable for applications requiring superior tolerance performance.

TNPW080545K3BYEA (Vishay Dale)

This cross-manufacturer substitute from Vishay Dale's TNPW e3 series maintains the 45.3 kOhms resistance value and 0805 package format. The part offers ±0.1% tolerance and increased power rating of 0.26W (compared to 0.125W), providing additional thermal margin. Operating temperature range extends to 175°C (versus 155°C maximum for Susumu variants). Moisture-resistant construction and AEC-Q200 qualification are included. This substitute is suitable for applications requiring higher power dissipation capability or extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-4532-B-T5 be used as a direct replacement for RG2012N-4532-C-T5?

A: Yes. The RG2012N-4532-B-T5 maintains identical resistance, power rating, package dimensions, and operating temperature range. The tighter tolerance (±0.1% versus ±0.25%) represents an improvement in accuracy. No circuit modifications are required.

Q: What is the difference between RG2012N-4532-W-T1 and RG2012N-4532-W-T5?

A: Both parts are electrically identical with ±0.05% tolerance. The difference is in tape reel specifications (T1 versus T5 format). Selection depends on assembly equipment compatibility and tape reel requirements.

Q: Why does TNPW080545K3BYEA have a higher power rating (0.26W) in the same 0805 package?

A: The Vishay Dale TNPW e3 series uses different construction techniques that allow higher power dissipation in the same physical package size. This provides additional thermal headroom for applications with higher current or power requirements.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, maintaining compliance with automotive reliability standards.

Q: Can TNPW080545K3BYEA be used in place of the Susumu parts?

A: Yes, provided the application can accommodate the higher power rating (0.26W) and extended operating temperature range (-55°C ~ 175°C). The 0805 package dimensions are identical, and AEC-Q200 qualification is maintained. Cross-manufacturer substitution requires verification of any specific design requirements related to the original manufacturer's specifications.

Q: What is the significance of the ±10ppm/°C temperature coefficient across all parts?

A: All parts maintain identical temperature coefficient performance, ensuring consistent resistance stability across the operating temperature range. This parameter is critical for precision analog circuits and does not vary among the listed substitutes.

Q: Are these parts suitable for high-reliability applications?

A: Yes. All listed parts are thin film resistors with AEC-Q200 automotive qualification, anti-sulfur construction, and RoHS3 compliance, making them suitable for high-reliability automotive and industrial applications.
