Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1676374-5 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 54.9 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)
• Termination Count: 2 (exact match required)

The substitute part RN73C2A54K9BTDF maintains identical electrical and mechanical specifications. The primary distinction is packaging configuration: the substitute is supplied in Tape & Reel (TR) format, whereas the main part number uses standard packaging. Both parts are manufactured by TE Connectivity Passive Product within the RN73 series.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 1676374-5 and RN73C2A54K9BTDF are Active products manufactured by TE Connectivity Passive Product. Selection between these parts is based on packaging and compliance requirements:

1676374-5 is suitable for applications requiring standard packaging configuration with vendor-defined compliance status.

RN73C2A54K9BTDF is the appropriate selection for high-volume production environments utilizing automated assembly processes, as it is supplied in Tape & Reel format. This part carries ROHS3 compliance certification and REACH Unaffected status, providing explicit regulatory documentation for applications subject to environmental compliance requirements.

Both parts are electrically and mechanically identical, with identical moisture sensitivity ratings (MSL 1 - Unlimited), operating temperature ranges (-55°C ~ 155°C), and dimensional specifications. The choice between them depends on procurement volume, assembly methodology, and regulatory documentation requirements rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Can RN73C2A54K9BTDF be used as a direct replacement for 1676374-5?

A: Yes. Both parts are electrically and mechanically identical. The RN73C2A54K9BTDF differs only in packaging format (Tape & Reel versus standard packaging). Functional performance, electrical characteristics, and physical dimensions are equivalent.

Q: What is the difference between the packaging formats?

A: The 1676374-5 uses standard packaging, while RN73C2A54K9BTDF is supplied in Tape & Reel (TR) format. Tape & Reel packaging is designed for automated pick-and-place assembly systems used in high-volume manufacturing. Standard packaging is typically used for lower-volume applications or manual assembly processes.

Q: Are there any compliance differences between these parts?

A: The RN73C2A54K9BTDF carries explicit ROHS3 compliance certification and REACH Unaffected status. The 1676374-5 has vendor-undefined REACH status and not applicable RoHS status. For applications requiring documented environmental compliance, the RN73C2A54K9BTDF is the specified choice.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited moisture sensitivity protection. No special moisture control measures are required during storage or handling.

Q: What is the temperature coefficient specification, and does it differ between parts?

A: Both parts have a temperature coefficient of ±10ppm/°C and operate across the identical temperature range of -55°C to 155°C. This specification indicates the resistor's resistance change per degree Celsius within the operating range.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0805 (2012 Metric) package size with dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.026" (0.65mm).

Q: What tolerance specification applies to both parts?

A: Both parts maintain ±0.1% tolerance on the 54.9 kOhms resistance value. This tight tolerance is characteristic of thin film resistor technology and is maintained across both part numbers.
