Equivalent & Substitute Parts for 1-2176094-7

Part Overview

The TE Connectivity 1-2176094-7 is a 174 kOhms ±0.1% thin film chip resistor in 0805 (2012 Metric) surface mount package rated for 0.25W (1/4W) power dissipation. This component is classified as Active product status and is designed for general-purpose SMD resistor applications requiring high precision and stability across industrial temperature ranges.

Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design requirements permit equivalent electrical and mechanical specifications. All substitute relationships are based strictly on matching resistance value, tolerance, package format, and thermal operating range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-2176094-7 is determined by the following critical parameters:

Primary Matching Criteria:

• Resistance value: 174 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Secondary Considerations:

• Power rating: Substitute parts may have equal or lower power ratings provided the application does not exceed the substitute's power dissipation limit
• RoHS and REACH compliance status may differ between main part and substitutes
• Automotive certifications (AEC-Q200) are present in some substitutes but not required for general-purpose applications

Both identified substitute parts (ERA-6AEB1743V and RT0805BRD07174KL) satisfy all primary matching criteria. The 1-2176094-7 is rated at 0.25W (1/4W), while both substitutes are rated at 0.125W (1/8W). This difference requires application-level verification to ensure power dissipation does not exceed 0.125W in the target circuit.

Parameter Comparison

Engineering Selection Recommendations

1-2176094-7 (TE Connectivity RP73P Series)

The primary part is Active status with RoHS non-compliant classification. Selection of this part is appropriate for applications without RoHS or REACH compliance requirements. The 0.25W power rating provides margin for circuits with moderate power dissipation in the 174 kOhms resistor element.

ERA-6AEB1743V (Panasonic ERA-6A Series)

This substitute is Active status with ROHS3 compliance and REACH Unaffected designation. The part includes AEC-Q200 automotive qualification, making it suitable for automotive and industrial applications requiring regulatory compliance. The 0.125W power rating is lower than the primary part. Selection is appropriate when RoHS3 compliance is required and circuit power dissipation does not exceed 0.125W.

RT0805BRD07174KL (YAGEO RT Series)

This substitute is Active status with ROHS3 compliance and REACH Unaffected designation. The part does not carry automotive certification. The 0.125W power rating is lower than the primary part. Selection is appropriate when RoHS3 compliance is required and circuit power dissipation does not exceed 0.125W.

All three parts share identical electrical specifications (174 kOhms, ±0.1%, ±25ppm/°C, -55°C ~ 155°C operating range) and mechanical compatibility (0805 package, 2-termination configuration). The primary differentiation factors are power rating, regulatory compliance status, and automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB1743V or RT0805BRD07174KL be used as direct replacements for 1-2176094-7?

A: Both parts are electrically and mechanically compatible with the 1-2176094-7. However, the substitute parts are rated at 0.125W (1/8W) compared to the primary part's 0.25W (1/4W) rating. Direct substitution is permissible only if the circuit application does not require power dissipation exceeding 0.125W in the resistor element. Circuit-level power analysis is required to confirm compatibility.

Q: What is the difference in physical dimensions between these parts?

A: All three parts use the 0805 (2012 Metric) package with identical length and width (0.079" L x 0.049" W / 2.00mm x 1.25mm). The seated height differs slightly: the primary part (1-2176094-7) has a maximum height of 0.026" (0.65mm), while both substitutes have a maximum height of 0.024" (0.60mm). This 0.002" (0.05mm) difference is within typical PCB assembly tolerances and does not affect mechanical compatibility.

Q: Are there RoHS compliance differences between these parts?

A: Yes. The primary part (1-2176094-7) is RoHS non-compliant. Both substitute parts (ERA-6AEB1743V and RT0805BRD07174KL) are ROHS3 compliant. If the application or end-market requires RoHS3 compliance, either substitute part is appropriate. The primary part must not be used in RoHS-regulated applications.

Q: Does the Panasonic ERA-6AEB1743V automotive qualification affect its use in non-automotive applications?

A: No. AEC-Q200 automotive qualification is an additional certification that does not restrict use in non-automotive applications. The ERA-6AEB1743V can be used in any application where the electrical and mechanical specifications are compatible, including general industrial and consumer applications.

Q: What is the temperature coefficient specification and why is it important?

A: All three parts have a temperature coefficient of ±25ppm/°C. This specification defines the maximum change in resistance value per degree Celsius across the operating temperature range (-55°C ~ 155°C). For a 174 kOhms resistor with ±25ppm/°C coefficient, the resistance change over the full temperature range is approximately ±0.44 kOhms. This specification is critical for precision analog circuits and must match across all substitute parts.

Q: Can these parts be used interchangeably in high-precision measurement circuits?

A: Yes, provided power dissipation limits are observed. All three parts share identical tolerance (±0.1%), temperature coefficient (±25ppm/°C), and composition (thin film). The electrical performance in precision circuits is equivalent. The primary constraint is the power rating difference: substitutes must not be used in circuits where resistor power dissipation exceeds 0.125W.

Q: What is Moisture Sensitivity Level (MSL) 1 and why is it the same across all parts?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. All three parts carry this designation, meaning they can be stored and handled under standard industrial conditions without special precautions or baking procedures prior to assembly.
