TE Connectivity 3-2176090-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 3-2176090-7 is a thin film chip resistor with a resistance value of 309 kOhms and a tolerance of ±0.1%. This component is packaged in the 0603 (1608 Metric) surface-mount form factor with a power rating of 0.167W (1/6W). The part is manufactured as part of the RP73P series from the Holsworthy product line and maintains an active product status. Substitute parts are identified to provide alternative sourcing options when the primary component becomes unavailable or when inventory constraints require alternative procurement channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 3-2176090-7 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 309 kOhms
• Tolerance: ±0.1%
• Package / Case: 0603 (1608 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: The substitute part may have a lower power rating (0.1W minimum) provided the application does not exceed the substitute's power dissipation capability. The main part operates at 0.167W; substitutes rated at 0.1W are acceptable for applications within this lower power envelope.

The Susumu RG1608P-3093-B-T5 meets all mandatory parameters and operates within the allowable power rating variation, qualifying it as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The Susumi RG1608P-3093-B-T5 qualifies as a direct substitute for the TE Connectivity 3-2176090-7 based on electrical and mechanical parameter equivalence. Both components are ROHS3 compliant and maintain identical resistance, tolerance, temperature coefficient, and operating temperature specifications.

The primary consideration for substitution is the power rating differential. The Susumu part is rated at 0.1W compared to the TE Connectivity part at 0.167W. Selection of the Susumu substitute is appropriate for applications where the actual power dissipation does not exceed 0.1W. Applications requiring the full 0.167W power capability must retain the TE Connectivity component.

The Susumu RG1608P-3093-B-T5 includes additional features: anti-sulfur construction and AEC-Q200 automotive qualification. These features do not preclude substitution in non-automotive applications and provide enhanced reliability in corrosive environments when specified.

Both components are packaged in 0603 (1608 Metric) form factor with identical termination configuration, ensuring mechanical and electrical compatibility in PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the Susumu RG1608P-3093-B-T5 be used as a direct replacement for the TE Connectivity 3-2176090-7?

A: The Susumu part qualifies as a substitute provided the application power dissipation does not exceed 0.1W. All other electrical and mechanical parameters are identical. PCB layout and assembly processes require no modification.

Q: What is the significance of the power rating difference between the two parts?

A: The TE Connectivity part is rated at 0.167W (1/6W) while the Susumu substitute is rated at 0.1W (1/10W). The substitute part has a lower maximum power dissipation capability. Applications operating below 0.1W power dissipation are unaffected by this difference. Applications requiring operation at or above 0.1W but below 0.167W must use the TE Connectivity component.

Q: Are the physical dimensions compatible between these two parts?

A: Both components use the 0603 (1608 Metric) package. The TE Connectivity part measures 0.061" L x 0.031" W with a maximum seated height of 0.022". The Susumu part measures 0.063" L x 0.031" W with a maximum seated height of 0.020". These minor dimensional variations are within standard PCB design tolerances and do not affect assembly compatibility.

Q: Do the additional features of the Susumu part (anti-sulfur, AEC-Q200) affect substitution suitability?

A: The anti-sulfur construction and AEC-Q200 automotive qualification are additional features that enhance the Susumu part's performance in specific environments. These features do not create incompatibility with the TE Connectivity part. Applications not requiring automotive qualification or anti-sulfur protection are unaffected by the presence of these features.

Q: What compliance certifications apply to both parts?

A: Both the TE Connectivity 3-2176090-7 and Susumu RG1608P-3093-B-T5 are ROHS3 compliant. Both components have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. The Susumu part carries AEC-Q200 automotive qualification; the TE Connectivity part does not specify this certification.

Q: Are there any temperature-related differences between these substitutes?

A: Both parts operate across the identical temperature range of -55°C to 155°C and share the same temperature coefficient of ±25ppm/°C. No temperature-related performance differentiation exists between the two components.
