Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1676345-5 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance Value: 45.3 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Power Rating: 0.1W / 1/10W (exact match required)
• Composition: Thin Film (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Temperature Coefficient: ±10ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Physical Dimensions: 0.079" L x 0.049" W / 2.00mm x 1.25mm (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Substitute parts must satisfy all parameters listed above to ensure functional and mechanical compatibility within the original application circuit and assembly process.

Parameter Comparison

Engineering Selection Recommendations

Both the 1676345-5 and RN73C2A45K3BTDF are Active status products from TE Connectivity Passive Product within the RN73 Holsworthy series. The parts are electrically and mechanically identical across all specified parameters.

The primary distinction between these parts is packaging configuration:

• 1676345-5: Supplied in bulk packaging
• RN73C2A45K3BTDF: Supplied in Tape & Reel (TR) format

Selection between these parts depends on manufacturing process requirements. Tape & Reel packaging is standard for automated pick-and-place assembly operations, while bulk packaging may be suitable for manual assembly or lower-volume applications.

The RN73C2A45K3BTDF carries ROHS3 Compliance and REACH Unaffected certifications, providing explicit regulatory documentation. The 1676345-5 lists RoHS Status as Not applicable and REACH Status as Vendor Undefined. Both parts carry identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications.

Frequently Asked Questions (FAQ)

Q: Can RN73C2A45K3BTDF be used as a direct replacement for 1676345-5?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical resistance value (45.3 kOhms), tolerance (±0.1%), power rating (0.1W), composition (thin film), package type (0805), temperature coefficient (±10ppm/°C), operating temperature range (-55°C ~ 155°C), physical dimensions, and moisture sensitivity level. The only difference is packaging format (bulk versus Tape & Reel).

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging contains loose components suitable for manual handling or small-scale assembly. Tape & Reel packaging places components in standardized carrier tape wound on reels, designed for automated surface mount assembly equipment. Selection depends on your manufacturing process and assembly method.

Q: Are there any compliance differences between these parts?

A: The RN73C2A45K3BTDF explicitly states ROHS3 Compliance and REACH Unaffected status. The 1676345-5 lists RoHS Status as Not applicable and REACH Status as Vendor Undefined. Both parts carry identical ECCN and HTSUS classifications. Verify compliance requirements with your regulatory or procurement department if these certifications are critical for your application.

Q: What does the temperature coefficient ±10ppm/°C mean?

A: The temperature coefficient specifies the maximum change in resistance value per degree Celsius across the operating temperature range. A ±10ppm/°C coefficient means the resistance will change by no more than 10 parts per million for each degree of temperature change within the -55°C to 155°C operating range.

Q: Can I substitute these parts with resistors from other manufacturers?

A: Substitution with parts from other manufacturers requires verification that all electrical and mechanical parameters match exactly: 45.3 kOhms resistance, ±0.1% tolerance, 0.1W power rating, thin film composition, 0805 package, ±10ppm/°C temperature coefficient, -55°C to 155°C operating range, and identical physical dimensions. Consult the alternative manufacturer's datasheet to confirm equivalence.

Q: What is the Moisture Sensitivity Level (MSL) 1 rating?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. No baking or desiccant storage is required prior to assembly.
