Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-4752-B-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 47.5 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Automotive AEC-Q200 qualification
• Anti-Sulfur feature
• RoHS3 compliance
• Moisture Sensitivity Level: 1

Allowable Variation Parameters:

• Tolerance: ±0.1% or tighter (±0.05%)
• Power rating: 0.125W or higher
• Operating temperature range: -55°C minimum and 155°C maximum or extended
• Packaging format: Bulk or Tape & Reel (TR)
• Product status: Active or Obsolete

Substitute parts meeting these criteria are functionally interchangeable in the original application without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Manufacturer, Active Status):

RG2012N-4752-B-T5 is the direct equivalent to RG2012N-4752-B-T1. Both parts share identical electrical specifications (47.5 kOhms ±0.1%, 0.125W, ±10ppm/°C) and mechanical dimensions. The primary difference is packaging format: RG2012N-4752-B-T5 is supplied in Tape & Reel format versus bulk packaging. RG2012N-4752-B-T5 carries active product status, ensuring continued availability and supply chain stability.

Upgraded Tolerance Option (Same Manufacturer, Active Status):

RG2012N-4752-W-T1 and RG2012N-4752-W-T5 offer tighter tolerance specification (±0.05% versus ±0.1%) while maintaining all other electrical and mechanical parameters. Both parts are supplied in Tape & Reel format and carry active product status. These parts are suitable for applications requiring enhanced precision without modification to circuit design or board layout.

Alternative Manufacturer Option (Active Status, Extended Temperature Range):

TNPW080547K5BYEA from Vishay Dale provides equivalent 47.5 kOhms ±0.1% resistance with identical package and composition. This part features higher power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C to 175°C versus -55°C to 155°C). TNPW080547K5BYEA includes moisture-resistant construction and carries active product status. This option is suitable for applications requiring thermal margin or higher power dissipation capability.

All substitute parts maintain AEC-Q200 automotive qualification, anti-sulfur construction, ROHS3 compliance, and MSL 1 rating, ensuring compatibility with original design requirements.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-4752-B-T5 be used as a direct replacement for RG2012N-4752-B-T1?

A: Yes. RG2012N-4752-B-T5 is a direct equivalent with identical electrical specifications (47.5 kOhms ±0.1%, 0.125W, ±10ppm/°C) and mechanical dimensions (0805 package). The only difference is packaging format (Tape & Reel versus bulk). No circuit modification is required.

Q: What is the difference between the ±0.1% and ±0.05% tolerance options?

A: Tolerance defines the maximum allowable deviation from the nominal 47.5 kOhms resistance value. ±0.1% tolerance allows deviation up to ±47.5 ohms, while ±0.05% tolerance restricts deviation to ±23.75 ohms. The ±0.05% option (RG2012N-4752-W-T1 and RG2012N-4752-W-T5) provides higher precision for applications requiring tighter resistance control.

Q: Is the TNPW080547K5BYEA from Vishay Dale compatible with the original design?

A: Yes. TNPW080547K5BYEA maintains the same 47.5 kOhms resistance, ±0.1% tolerance, 0805 package, thin film composition, and AEC-Q200 qualification. The higher power rating (0.26W) and extended temperature range (-55°C to 175°C) provide additional design margin without affecting circuit functionality.

Q: Does packaging format (Tape & Reel versus bulk) affect electrical performance?

A: No. Packaging format affects only supply and handling logistics. Tape & Reel format is standard for automated assembly processes, while bulk packaging is used for manual assembly or lower-volume applications. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Are all substitute parts RoHS3 compliant and AEC-Q200 qualified?

A: Yes. All listed substitute parts (RG2012N-4752-B-T5, RG2012N-4752-W-T1, RG2012N-4752-W-T5, and TNPW080547K5BYEA) are ROHS3 compliant and carry AEC-Q200 automotive qualification. All parts feature anti-sulfur construction and MSL 1 rating.

Q: What is the temperature coefficient specification and why is it important?

A: Temperature coefficient (±10ppm/°C) specifies the maximum change in resistance per degree Celsius across the operating temperature range. All listed parts share this specification, ensuring consistent performance across -55°C to 155°C (or -55°C to 175°C for TNPW080547K5BYEA).

Q: Can I mix different substitute parts in the same assembly?

A: Yes. All substitute parts are electrically and mechanically equivalent. Mixed usage within a single assembly does not affect circuit performance, provided the application does not require matched resistance values across multiple components.
