Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-8661-D-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 8.66 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: The main part specifies ±0.5%. Substitute parts with ±0.1% tolerance provide improved accuracy and are considered upgrades.
• Power Rating: The main part is rated 0.125W (1/8W). Substitute parts rated 0.25W (1/4W) or higher provide additional thermal margin.
• Automotive Certification: The main part includes AEC-Q200 rating. Substitute parts with or without this certification are functionally compatible; AEC-Q200 rated substitutes provide enhanced reliability assurance.

All identified substitute parts maintain the same resistance value, package footprint, and thin film composition, ensuring direct PCB compatibility and electrical performance equivalence within the specified tolerance ranges.

Parameter Comparison

Engineering Selection Recommendations

RG2012P-8661-B-T5 (Susumu Upgrade) This part is a direct upgrade from the main part, maintaining identical package dimensions, power rating, and automotive AEC-Q200 certification while improving tolerance from ±0.5% to ±0.1%. Selection is appropriate for applications requiring tighter resistance accuracy without design modification. Highest inventory availability (9525 units) supports production continuity.

9-2176092-8 (TE Connectivity Direct Substitute) This TE Connectivity part maintains the 8.66 kOhms resistance and 0805 package with improved tolerance (±0.1%) and elevated power rating (0.25W). The increased seated height (0.026" vs. 0.020") requires verification of PCB clearance constraints. Absence of AEC-Q200 certification limits application to non-automotive environments. Suitable for general-purpose industrial applications.

ERA-6AEB8661V (Panasonic Upgrade) Panasonic's ERA-6A series part provides ±0.1% tolerance and AEC-Q200 automotive qualification matching the main part's reliability requirements. Seated height of 0.024" remains within typical PCB assembly tolerances. High inventory (4321 units) ensures supply availability. Recommended for automotive and high-reliability applications requiring tolerance improvement.

RT0805BRD078K66L (YAGEO Upgrade) YAGEO's RT series offers ±0.1% tolerance in the 0805 package with matching temperature coefficient and operating range. Seated height of 0.024" is compatible with standard PCB designs. Absence of AEC-Q200 certification restricts use to non-automotive applications. Largest inventory (8395 units) provides excellent supply security for high-volume production.

All substitute parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-8661-B-T5 be used as a direct replacement for RG2012P-8661-D-T5?

A: Yes. Both parts are manufactured by Susumu in the 0805 package with identical power rating (0.125W), temperature coefficient (±25ppm/°C), and operating range (-55°C to 155°C). The RG2012P-8661-B-T5 provides improved tolerance (±0.1% vs. ±0.5%), making it a functional upgrade with no design changes required.

Q: What is the significance of the tolerance difference between ±0.5% and ±0.1%?

A: Tolerance defines the allowable deviation from the nominal 8.66 kOhms resistance value. The ±0.5% specification permits resistance between 8.623 kOhms and 8.697 kOhms, while ±0.1% restricts the range to 8.657 kOhms and 8.663 kOhms. Applications requiring precise voltage dividers, filter networks, or gain-setting circuits benefit from the tighter tolerance of ±0.1% parts.

Q: Is the 9-2176092-8 suitable for automotive applications?

A: The 9-2176092-8 lacks AEC-Q200 automotive qualification. While electrically compatible with the main part, it is not certified for automotive environments. For automotive applications, select ERA-6AEB8661V or RG2012P-8661-B-T5, both carrying AEC-Q200 ratings.

Q: Does the seated height difference affect PCB assembly?

A: The main part specifies 0.020" (0.50mm) maximum seated height. Substitute parts range from 0.020" to 0.026" (0.50mm to 0.65mm). Standard PCB designs accommodate this variation. Verify clearance only if the PCB has height-constrained components or conformal coating requirements in the immediate vicinity.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 Compliant status, meeting environmental and hazardous substance restrictions for EU and global markets.

Q: Which substitute part offers the best inventory availability?

A: RT0805BRD078K66L (YAGEO) provides the highest inventory with 8395 units in stock, followed by RG2012P-8661-B-T5 (Susumu) with 9525 units. Both support high-volume production requirements.

Q: Can I use ERA-6AEB8661V in place of RG2012P-8661-D-T5 without circuit redesign?

A: Yes. The ERA-6AEB8661V maintains the same 8.66 kOhms resistance, 0805 package, ±25ppm/°C temperature coefficient, and -55°C to 155°C operating range. The improved ±0.1% tolerance and AEC-Q200 certification provide enhanced performance without requiring design modifications.

Q: What is the difference between the main part and its direct substitute 9-2176092-8?

A: The primary differences are power rating (0.125W vs. 0.25W), tolerance (±0.5% vs. ±0.1%), seated height (0.020" vs. 0.026"), and automotive certification (AEC-Q200 vs. none). The 9-2176092-8 is suitable for non-automotive applications where higher power dissipation margin is beneficial.
