Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012Q-13R3-D-T5 is permissible when the following conditions are met:

Critical Parameters for Substitution:

• Resistance value must be 13.3 Ohms
• Package must be 0805 (2012 Metric) to ensure mechanical and electrical compatibility
• Operating temperature range must encompass -55°C to 155°C
• Composition must be thin film for performance consistency
• RoHS3 compliance must be maintained

Relaxable Parameters:

• Tolerance may be tighter (lower value) than ±0.5%
• Power rating may be equal to or greater than 0.125W
• Temperature coefficient may be equal to or lower in absolute value than ±50ppm/°C
• Automotive qualification (AEC-Q200) and anti-sulfur features are not required for substitution but represent enhanced specifications

The substitute part 3-1625868-9 meets all critical substitution criteria with improved tolerance (±0.1%) and higher power rating (0.25W), making it a valid alternative for applications where these enhanced specifications are acceptable.

Engineering Selection Recommendations

Primary Part Selection: The RG2012Q-13R3-D-T5 is recommended for applications requiring AEC-Q200 automotive qualification and anti-sulfur coating. This part maintains active production status with adequate inventory availability.

Substitute Part Selection: The 3-1625868-9 from TE Connectivity is a valid substitute when the following conditions apply:

• Applications do not require AEC-Q200 automotive qualification
• Tighter tolerance specification (±0.1% versus ±0.5%) is acceptable or beneficial
• Higher power dissipation capability (0.25W versus 0.125W) is acceptable
• Slightly increased component height (0.026" versus 0.020") does not create PCB layout constraints
• Lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) is acceptable

Both parts maintain ROHS3 compliance, identical resistance values, matching package dimensions in length and width, and identical operating temperature ranges. The substitute part offers improved electrical performance characteristics while maintaining mechanical compatibility with 0805 footprints.

Frequently Asked Questions (FAQ)

Q: Can the 3-1625868-9 be used as a direct replacement for the RG2012Q-13R3-D-T5 in automotive applications?

A: The 3-1625868-9 lacks AEC-Q200 automotive qualification. Use only in non-automotive applications or where automotive qualification is not a design requirement.

Q: What is the impact of the height difference between these parts?

A: The RG2012Q-13R3-D-T5 has a maximum seated height of 0.020" (0.50mm), while the 3-1625868-9 measures 0.026" (0.65mm). This 0.006" (0.15mm) difference is negligible for most PCB designs but must be verified for applications with strict height constraints or high-density layouts.

Q: Are both parts compatible with the same PCB footprint?

A: Yes. Both parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049") dimensions. PCB footprints designed for 0805 components accommodate both parts.

Q: What is the significance of the tolerance difference?

A: The RG2012Q-13R3-D-T5 offers ±0.5% tolerance, while the 3-1625868-9 provides ±0.1% tolerance. The substitute part delivers tighter resistance value control, which may improve circuit performance in precision applications.

Q: Can the substitute part handle higher power dissipation?

A: Yes. The 3-1625868-9 is rated for 0.25W (1/4W) compared to the primary part's 0.125W (1/8W) rating. This provides additional thermal margin in applications approaching the power limits of the original component.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The primary part includes anti-sulfur coating and AEC-Q200 qualification; the substitute part does not include these features.

Q: What is the temperature coefficient significance?

A: The RG2012Q-13R3-D-T5 has a temperature coefficient of ±50ppm/°C, while the 3-1625868-9 is ±25ppm/°C. The substitute part exhibits half the resistance drift over temperature, beneficial for temperature-sensitive circuit applications.
