Substitute Part Grouping Explanation

Substitution of the RGH2012-2E-P-431-B is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 430 Ohms
• Tolerance: ±0.1%
• Package format: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variation:

• Power rating may be equal to or greater than the original 0.25W specification
• Product status may transition from obsolete to active
• Packaging format may differ (bulk to Tape & Reel)
• Additional features (Anti-Sulfur, AEC-Q200 certification) do not disqualify substitution

The identified substitute RG2012P-431-B-T5 meets all mandatory matching parameters while offering enhanced features and active product status.

Parameter Comparison

Engineering Selection Recommendations

The RG2012P-431-B-T5 is a direct functional equivalent to the RGH2012-2E-P-431-B for applications requiring 430 Ohm thin film resistors in 0805 package format with ±0.1% tolerance. Both components share identical electrical specifications, physical dimensions, and environmental ratings.

Selection Basis:

The substitute part maintains full compliance with ROHS3 and MSL 1 requirements. The transition from obsolete to active product status ensures long-term availability and supply chain continuity. The RG2012P-431-B-T5 incorporates Anti-Sulfur composition and AEC-Q200 automotive qualification, providing enhanced reliability characteristics without compromising compatibility.

The power rating differential (0.125W versus 0.25W) requires circuit-level evaluation. Applications operating at or below 0.125W dissipation levels experience no functional impact. Circuits requiring sustained power dissipation exceeding 0.125W must source alternative components rated at 0.25W or higher.

The packaging transition from bulk to Tape & Reel format affects procurement and assembly processes but does not alter electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the RG2012P-431-B-T5 directly replace the RGH2012-2E-P-431-B in all applications?

A: Direct replacement is valid for applications where power dissipation does not exceed 0.125W. The substitute component is rated for 1/8W (0.125W) versus the original 1/4W (0.25W) specification. Circuit analysis must confirm that actual power dissipation remains within the substitute's rating.

Q: What is the significance of the Anti-Sulfur and AEC-Q200 features on the substitute part?

A: Anti-Sulfur composition provides enhanced resistance to sulfur-containing environmental contaminants. AEC-Q200 certification indicates compliance with automotive industry reliability standards. These features enhance component robustness but do not alter electrical performance or compatibility with the original specification.

Q: Does the Tape & Reel packaging affect electrical performance?

A: Packaging format does not affect electrical or mechanical performance. Tape & Reel packaging is a supply and assembly format consideration only. Component electrical characteristics, physical dimensions, and environmental ratings remain identical to bulk packaging.

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

A: Yes. Both components are 0805 (2012 Metric) package format with identical length (0.079" / 2.00mm), width (0.049" / 1.25mm), and maximum seated height (0.020" / 0.50mm). PCB footprints and assembly processes are interchangeable.

Q: What compliance certifications apply to both parts?

A: Both the RGH2012-2E-P-431-B and RG2012P-431-B-T5 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. MSL rating of 1 (Unlimited) applies to both components, indicating no moisture sensitivity restrictions.

Q: How does the temperature coefficient affect substitution?

A: Both components share an identical temperature coefficient of ±25ppm/°C and operate across the same temperature range (-55°C to 155°C). Temperature-dependent performance characteristics are equivalent.

Q: Is the ±0.1% tolerance maintained in the substitute part?

A: Yes. The RG2012P-431-B-T5 maintains the same ±0.1% tolerance specification as the original RGH2012-2E-P-431-B, ensuring equivalent precision for tolerance-critical applications.
