Parameter Comparison

Engineering Selection Recommendations

All three part numbers—1676354-5, RN73C2A4K02BTD, and RN73C2A4K02BTDF—are Active status products from TE Connectivity and are electrically and mechanically equivalent for circuit design purposes.

RN73C2A4K02BTD and RN73C2A4K02BTDF provide enhanced compliance documentation with ROHS3 Compliant and REACH Unaffected certifications, compared to the main part number 1676354-5 which lists RoHS Status as Not applicable and REACH Status as Vendor Undefined. Both substitute parts are supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes.

Selection between RN73C2A4K02BTD and RN73C2A4K02BTDF is determined by specific procurement, supply chain, or manufacturing requirements, as both parts are electrically and mechanically identical. The choice between the main part number and the substitute parts depends on packaging format requirements and compliance certification needs for the end application.

Frequently Asked Questions (FAQ)

Q: Can RN73C2A4K02BTD or RN73C2A4K02BTDF be used as direct replacements for 1676354-5 in circuit design?

A: Yes. All three part numbers are electrically and mechanically equivalent. They share identical resistance value (4.02 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), and physical dimensions. Substitution is valid from a circuit performance standpoint.

Q: What is the primary difference between 1676354-5 and the substitute parts?

A: The primary differences are packaging format and compliance certifications. The substitute parts RN73C2A4K02BTD and RN73C2A4K02BTDF are supplied in Tape & Reel (TR) packaging, whereas the main part number packaging format is not specified. Additionally, the substitute parts carry ROHS3 Compliant and REACH Unaffected certifications, while the main part number lists these as Not applicable and Vendor Undefined respectively.

Q: Are RN73C2A4K02BTD and RN73C2A4K02BTDF interchangeable with each other?

A: Yes. Both substitute parts are electrically and mechanically identical. The difference in part number designation (BTD versus BTDF) does not reflect differences in electrical performance, physical dimensions, or functional characteristics. Selection between these two parts is based on supply chain availability or specific procurement requirements.

Q: What does the 0805 package designation mean?

A: 0805 refers to the Surface Mount Device (SMD) package size in both imperial and metric notation. The designation represents 0.080" x 0.050" in imperial units, equivalent to 2.00mm x 1.25mm in metric units. All three part numbers use this identical package format, ensuring mechanical compatibility on printed circuit boards.

Q: Is the ±0.1% tolerance specification maintained across all three part numbers?

A: Yes. The ±0.1% tolerance specification is maintained across 1676354-5, RN73C2A4K02BTD, and RN73C2A4K02BTDF. This tight tolerance is characteristic of thin film resistor technology and is consistent across all equivalent parts.

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

A: The temperature coefficient is ±10ppm/°C for all three part numbers. This specification indicates the maximum change in resistance value per degree Celsius of temperature change. A lower temperature coefficient value indicates better stability across the operating temperature range (-55°C ~ 155°C), which is critical for precision measurement and analog circuit applications.

Q: Are these parts suitable for automated assembly?

A: RN73C2A4K02BTD and RN73C2A4K02BTDF are supplied in Tape & Reel (TR) packaging format, which is standard for automated pick-and-place assembly processes. The main part number 1676354-5 does not specify a packaging format, which may indicate bulk or alternative packaging suitable for manual assembly or specific handling requirements.
