Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-1780-D-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 178 Ohms
• Package format: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: May be equal or tighter (±0.5% or better)
• Power rating: May be equal or higher (0.125W or greater)
• Automotive qualification: May be present or absent
• Physical height: Variation acceptable within standard 0805 specifications

The identified substitute parts meet these criteria and are classified as direct equivalents or upgrades based on tolerance and power rating specifications.

Parameter Comparison

Engineering Selection Recommendations

RG2012P-1780-D-T5 (Primary Part): Select this part for applications requiring automotive-grade components with AEC-Q200 qualification, anti-sulfur coating, and the specified tolerance of ±0.5%. This part maintains the original design specification and is recommended for direct replacement in existing designs.

4-2176091-8 (TE Connectivity - Direct Equivalent): This part provides tighter tolerance (±0.1%) and higher power rating (0.25W) in the same 0805 package. It is suitable for applications where improved tolerance performance is beneficial. However, this part does not carry AEC-Q200 automotive qualification. REACH compliance status is vendor-undefined. Use this part only in non-automotive applications or where automotive qualification is not required.

ERA-6AEB1780V (Panasonic - Upgrade Equivalent): This part offers tighter tolerance (±0.1%) while maintaining the same power rating (0.125W) and AEC-Q200 automotive qualification as the primary part. It provides REACH Unaffected status and is fully compliant with automotive standards. This part is suitable as a direct upgrade for automotive applications requiring improved tolerance performance without power rating changes.

Frequently Asked Questions (FAQ)

Q: Can the 4-2176091-8 be used as a direct replacement for the RG2012P-1780-D-T5?

A: The 4-2176091-8 is electrically compatible in terms of resistance value, package format, and temperature characteristics. However, it lacks AEC-Q200 automotive qualification and has undefined REACH compliance status. Use this part only in applications where automotive qualification is not required.

Q: What is the primary advantage of the ERA-6AEB1780V over the RG2012P-1780-D-T5?

A: The ERA-6AEB1780V provides tighter tolerance (±0.1% versus ±0.5%) while maintaining AEC-Q200 automotive qualification and the same power rating. This makes it suitable for applications requiring improved accuracy without sacrificing automotive compliance.

Q: Are all three parts suitable for automotive applications?

A: The RG2012P-1780-D-T5 and ERA-6AEB1780V both carry AEC-Q200 qualification and are suitable for automotive applications. The 4-2176091-8 does not have automotive qualification and should not be used in automotive designs.

Q: Do the substitute parts have different physical dimensions?

A: All three parts use the 0805 (2012 Metric) package format with identical length and width (0.079" L x 0.049" W). Maximum seated heights vary slightly: RG2012P-1780-D-T5 at 0.020" (0.50mm), ERA-6AEB1780V at 0.024" (0.60mm), and 4-2176091-8 at 0.026" (0.65mm). These variations are within standard 0805 package tolerances.

Q: What is the difference in power rating between the parts?

A: The RG2012P-1780-D-T5 and ERA-6AEB1780V are both rated for 0.125W (1/8W). The 4-2176091-8 is rated for 0.25W (1/4W), providing higher power dissipation capability. The higher power rating does not affect compatibility in applications using the lower rating.

Q: Are all parts RoHS3 compliant?

A: Yes, all three parts are ROHS3 compliant. The RG2012P-1780-D-T5 and ERA-6AEB1780V are REACH Unaffected. The 4-2176091-8 has vendor-undefined REACH status.

Q: Can tolerance differences affect circuit performance?

A: Tolerance differences between ±0.5% and ±0.1% may affect circuit performance in precision applications. The tighter tolerance of the substitute parts (±0.1%) provides improved accuracy. Verify tolerance requirements for your specific application before substitution.
