Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-6813-B-T1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 681 kOhms
• Tolerance: ±0.1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C (or tighter)
• Operating Temperature Range: Minimum -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Flexible Parameters (May Vary):

• Power Rating: 0.125W minimum (higher ratings acceptable)
• Manufacturer: Different manufacturers acceptable
• Packaging format: Tape & Reel acceptable for bulk applications
• Additional features: Anti-sulfur, AEC-Q200 certification, moisture resistance enhance compatibility but are not required for basic substitution

Substitute parts are grouped into two categories: direct equivalents (matching all parameters including power rating) and upgrades (enhanced specifications such as higher power rating or improved temperature coefficient).

Parameter Comparison

Engineering Selection Recommendations

Primary Direct Equivalents (Recommended for Direct Replacement):

RG2012P-6813-B-T5 (Susumu) is the primary recommended substitute. This part is manufactured by the same supplier as the obsolete RG2012P-6813-B-T1 and maintains identical electrical specifications and package dimensions. The only difference is packaging format (Tape & Reel vs. bulk), making it the most straightforward replacement for production environments.

RT0805BRD07681KL (YAGEO) provides an active, widely available alternative with full parameter compatibility. With 7324 pieces in stock, this part offers supply chain reliability and is suitable for applications where supplier diversification is beneficial.

ERA-6AEB6813V (Panasonic Electronic Components) is an active equivalent with AEC-Q200 automotive qualification matching the original part's automotive-grade specification. This part is appropriate for automotive and mission-critical applications.

Secondary Equivalents (Compatible with Minor Considerations):

MCU08050D6813BP100 (Vishay Beyschlag/Draloric/BC Components) is electrically equivalent but specifies a maximum operating temperature of 125°C compared to the original 155°C. This part is suitable for applications where the upper temperature limit does not exceed 125°C.

Upgrade Options (Enhanced Specifications):

TNPW0805681KBEEA and TNPW0805681KBEEN (Vishay Dale) both provide upgraded specifications with 0.26W power rating (versus 0.125W) and extended operating temperature range to 175°C. These parts are suitable for applications requiring higher power dissipation capability or extended temperature operation. Both variants are electrically interchangeable with identical electrical performance.

RP73D2A681KBTDF (TE Connectivity Passive Product) offers an upgrade path with improved temperature coefficient of ±15ppm/°C (versus ±25ppm/°C), providing enhanced temperature stability for precision applications. This part maintains all other electrical and mechanical compatibility.

Compliance and Certification:

All recommended substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) rating, ensuring compatibility with modern manufacturing and storage requirements. Parts with AEC-Q200 certification (RG2012P-6813-B-T5, ERA-6AEB6813V, TNPW0805681KBEEA, TNPW0805681KBEEN) are suitable for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can I use TNPW0805681KBEEA or TNPW0805681KBEEN as direct replacements for RG2012P-6813-B-T1?

A: Yes. These parts are electrically compatible with identical resistance, tolerance, temperature coefficient, and package specifications. The higher power rating (0.26W vs. 0.125W) and extended temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C) represent enhancements that do not compromise compatibility. The parts are physically interchangeable in 0805 package footprints.

Q: What is the difference between RG2012P-6813-B-T1 and RG2012P-6813-B-T5?

A: Both parts are manufactured by Susumu with identical electrical specifications (681 kOhms ±0.1%, 0.125W, ±25ppm/°C). The primary difference is packaging: RG2012P-6813-B-T1 is supplied in bulk format while RG2012P-6813-B-T5 is supplied in Tape & Reel format. RG2012P-6813-B-T5 is currently active in production, making it the recommended replacement for the obsolete RG2012P-6813-B-T1.

Q: Is MCU08050D6813BP100 suitable for all applications using RG2012P-6813-B-T1?

A: MCU08050D6813BP100 is suitable for applications where the maximum operating temperature does not exceed 125°C. The original part specifies -55°C ~ 155°C operation, while this substitute specifies -55°C ~ 125°C. For applications requiring operation above 125°C, alternative substitutes with higher temperature ratings should be selected.

Q: Why does RP73D2A681KBTDF have a different temperature coefficient?

A: RP73D2A681KBTDF is manufactured by TE Connectivity and features a tighter temperature coefficient of ±15ppm/°C compared to the original ±25ppm/°C specification. This represents an upgrade in temperature stability performance. The part remains electrically compatible and is suitable for precision applications requiring enhanced temperature coefficient performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) rating, ensuring compatibility with current manufacturing standards and environmental regulations.

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

A: Yes. All substitute parts maintain identical electrical specifications (681 kOhms ±0.1%, thin film composition, ±25ppm/°C temperature coefficient) and are physically interchangeable in 0805 package footprints. However, design documentation should be updated to reflect the specific part number used in each production lot for traceability and future service requirements.

Q: Which substitute offers the best supply chain availability?

A: RT0805BRD07681KL (YAGEO) currently has the highest inventory level at 7324 pieces in stock, providing the most immediate supply chain availability. TNPW0805681KBEEA (Vishay Dale) is the second option with 9721 pieces available.

Q: What is the height difference between substitute parts, and does it matter?

A: Substitute parts have maximum seated heights ranging from 0.50mm to 0.65mm. The original RG2012P-6813-B-T1 specifies 0.50mm maximum height. For applications with tight vertical clearance constraints, RG2012P-6813-B-T5 (0.50mm) and TNPW0805681KBEEA/TNPW0805681KBEEN (0.55mm) are preferred. For most standard PCB applications, height variations within this range are not functionally significant.
