Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-6652-B-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 66.5 kOhms
• Package type: 0805 (2012 Metric)
• Composition: Thin Film
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Tolerance: ±0.1% or tighter (±0.05%)
• Power rating: 0.125W or higher
• Temperature coefficient: ±10ppm/°C or ±25ppm/°C
• Operating temperature range: -55°C ~ 155°C or extended to -55°C ~ 175°C
• Packaging format: Tape & Reel (TR) acceptable for obsolete part replacement
• Anti-sulfur feature: Present or absent (not mandatory for substitution)

Substitute parts are grouped by substitution type: direct equivalents maintain identical electrical specifications, upgrade substitutes provide improved tolerance or power rating, and similar substitutes maintain core functionality with minor specification variations.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Substitution: RG2012N-6652-B-T5 provides direct electrical and mechanical equivalence to the RG2012N-6652-B-T1. Both components share identical resistance, tolerance, power rating, and temperature specifications. The primary difference is packaging format (Tape & Reel versus bulk) and active product status. This part is suitable for direct replacement in all applications where the obsolete RG2012N-6652-B-T1 was specified.

Upgrade Substitution (Improved Tolerance): RG2012N-6652-W-T1 and RG2012N-6652-W-T5 offer tighter tolerance (±0.05% versus ±0.1%) while maintaining all other electrical and mechanical parameters. These Susumu components are appropriate for applications requiring enhanced precision. Both are available in Tape & Reel packaging and maintain active product status.

Upgrade Substitution (Enhanced Power Rating): TNPW080566K5BYEA from Vishay Dale provides increased power dissipation capability (0.26W versus 0.125W) with identical resistance and tolerance specifications. This component extends the operating temperature range to -55°C ~ 175°C and includes moisture-resistant coating. Selection of this part is appropriate for applications with higher thermal stress or extended temperature requirements.

Similar Substitution (Alternative Manufacturer): ERA-6AEB6652V from Panasonic Electronic Components maintains core electrical specifications (66.5 kOhms, ±0.1%, 0.125W) with AEC-Q200 qualification. The temperature coefficient specification differs (±25ppm/°C versus ±10ppm/°C), and physical height is slightly increased (0.024" versus 0.020"). This part is suitable for applications where manufacturer diversity is required and the higher temperature coefficient is acceptable.

All substitute parts maintain ROHS3 compliance and AEC-Q200 automotive qualification, ensuring regulatory and reliability requirements are met.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-6652-B-T5 be used as a direct replacement for RG2012N-6652-B-T1?

A: Yes. RG2012N-6652-B-T5 is electrically and mechanically identical to RG2012N-6652-B-T1. The only difference is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete). All electrical parameters, tolerance, power rating, and temperature specifications are identical.

Q: What is the advantage of selecting RG2012N-6652-W-T1 or RG2012N-6652-W-T5 over the direct equivalent?

A: These upgrade parts provide tighter tolerance specification (±0.05% versus ±0.1%), resulting in improved resistance accuracy. Selection is appropriate for precision analog circuits, reference networks, or applications where tighter tolerance improves overall system performance.

Q: When should TNPW080566K5BYEA be selected instead of the Susumu equivalents?

A: TNPW080566K5BYEA is selected when applications require higher power dissipation capability (0.26W versus 0.125W) or extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). The moisture-resistant coating provides additional environmental protection. This part is suitable for high-reliability automotive applications with elevated thermal stress.

Q: Is ERA-6AEB6652V a suitable substitute if the application requires ±10ppm/°C temperature coefficient?

A: ERA-6AEB6652V has a temperature coefficient of ±25ppm/°C, which is higher than the original specification of ±10ppm/°C. This part is suitable only for applications where the higher temperature coefficient does not impact circuit performance. For temperature-sensitive applications, Susumu RG series parts (RG2012N-6652-B-T5, RG2012N-6652-W-T1, or RG2012N-6652-W-T5) are preferred.

Q: Are all substitute parts available in 0805 package format?

A: Yes. All substitute parts listed are available in 0805 (2012 Metric) package format with identical footprint dimensions (0.079" L x 0.049" W). Physical height varies slightly between manufacturers (0.020" to 0.024" seated height), which is within standard PCB assembly tolerances.

Q: Do all substitute parts meet automotive AEC-Q200 qualification?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification and ROHS3 compliance, meeting regulatory requirements for automotive and high-reliability applications.

Q: What is the difference between Tape & Reel and bulk packaging?

A: Tape & Reel (TR) packaging is the standard format for automated assembly processes and is suitable for production environments. Bulk packaging is typically used for prototype or small-quantity applications. The RG2012N-6652-B-T1 is supplied in bulk format, while all active substitute parts are supplied in Tape & Reel format.

Q: Can multiple substitute parts be used interchangeably within the same design?

A: Substitution interchangeability depends on application requirements. For general-purpose applications, RG2012N-6652-B-T5 and ERA-6AEB6652V are interchangeable. For precision applications, RG2012N-6652-W-T1 or RG2012N-6652-W-T5 are preferred. For high-power or extended-temperature applications, TNPW080566K5BYEA is appropriate. Circuit design specifications determine which substitute is suitable.
