Substitute Part Grouping Explanation

Substitution of the RGH2012-2E-P-470-B is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 47 Ohms
• Tolerance: ±0.1%
• 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:

• Power Rating: The substitute part RG2012P-470-B-T5 operates at 0.125W (1/8W), which is lower than the original 0.25W (1/4W) rating. This represents a derating scenario where the substitute can be used in applications where the actual power dissipation does not exceed 0.125W.

The substitute part RG2012P-470-B-T5 maintains all critical electrical and mechanical specifications while offering enhanced features including anti-sulfur coating and AEC-Q200 automotive qualification. The part is currently in active production status, ensuring long-term availability.

Parameter Comparison

Engineering Selection Recommendations

The RG2012P-470-B-T5 serves as the primary substitute for the obsolete RGH2012-2E-P-470-B. Both components are manufactured by Susumu and maintain identical electrical specifications including 47 Ohm resistance, ±0.1% tolerance, and ±25ppm/°C temperature coefficient across the -55°C to 155°C operating range.

The substitute part is currently in active production status, providing assured long-term availability and supply chain continuity. Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard handling and storage procedures.

The RG2012P-470-B-T5 incorporates anti-sulfur coating and holds AEC-Q200 automotive qualification, features not present in the original part. These enhancements provide additional reliability margins in demanding environments without introducing incompatibility with existing designs.

The primary design consideration is the power rating differential: the substitute operates at 0.125W (1/8W) compared to the original 0.25W (1/4W). Substitution is valid only when actual circuit power dissipation remains below 0.125W. Applications requiring the full 0.25W power rating require alternative component selection outside this substitute relationship.

Frequently Asked Questions (FAQ)

Q: Can the RG2012P-470-B-T5 directly replace the RGH2012-2E-P-470-B in all applications?

A: Direct replacement is valid only when circuit power dissipation does not exceed 0.125W. The substitute part is rated for 1/8W power handling, compared to the original 1/4W rating. If the application requires the full 0.25W power dissipation capability, the substitute is not appropriate.

Q: Are the physical dimensions identical between the main part and substitute?

A: Yes. Both components use the 0805 (2012 Metric) package with identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.020" (0.50mm). PCB layout and footprint compatibility is maintained.

Q: What is the significance of the AEC-Q200 qualification on the substitute part?

A: AEC-Q200 is an automotive industry qualification standard. The RG2012P-470-B-T5 meets this specification, indicating suitability for automotive applications. The original RGH2012-2E-P-470-B does not carry this qualification. This enhancement does not create incompatibility with non-automotive applications.

Q: How do the tolerance specifications compare?

A: Both parts maintain ±0.1% tolerance, ensuring identical precision in resistance value. No tolerance degradation occurs with substitution.

Q: What is the difference between the packaging formats listed?

A: The main part RGH2012-2E-P-470-B is listed with packaging designation "-" (unspecified). The substitute RG2012P-470-B-T5 is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. This represents a packaging format upgrade without affecting component performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the RGH2012-2E-P-470-B and RG2012P-470-B-T5 are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the lowest moisture sensitivity level. Components with this rating require no special moisture control during storage, handling, or assembly. Both parts carry this rating, ensuring compatibility with standard manufacturing environments.

Q: Why is the original part classified as obsolete?

A: The RGH2012-2E-P-470-B is no longer in active production. The RG2012P-470-B-T5 represents the current active equivalent from the same manufacturer, offering improved features and assured supply continuity.
