Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1676438-5 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 7.68 kOhms (exact match required)
• Tolerance: ±0.1% (precision specification)
• Power Rating: 0.1W / 1/10W (thermal dissipation capacity)
• Composition: Thin Film (electrical performance characteristics)
• Package / Case: 0805 (2012 Metric) (PCB footprint compatibility)
• Temperature Coefficient: ±10ppm/°C (temperature stability)
• Operating Temperature Range: -55°C ~ 155°C (environmental limits)
• Termination Count: 2 (circuit connectivity)
• Moisture Sensitivity Level: 1 (Unlimited) (assembly process compatibility)

The substitute part RN73C2A7K68BTDF maintains identical electrical and mechanical specifications across all parameters listed above. The primary distinction is packaging format: the main part is supplied in standard packaging, while the substitute is supplied in Tape & Reel (TR) format for automated assembly operations.

Parameter Comparison

Engineering Selection Recommendations

Both the main part 1676438-5 and substitute part RN73C2A7K68BTDF are Active status components from TE Connectivity's RN73 series. Selection between these parts is determined by packaging and compliance requirements:

Select 1676438-5 when standard packaging format is required for manual assembly, prototyping, or low-volume applications.

Select RN73C2A7K68BTDF when Tape & Reel (TR) packaging is required for automated pick-and-place assembly operations. This substitute additionally provides explicit ROHS3 compliance certification and REACH Unaffected status, offering enhanced regulatory documentation clarity compared to the main part's undefined compliance status.

Both parts maintain identical electrical performance, thermal characteristics, and mechanical compatibility with 0805 (2012 Metric) PCB footprints. The thin film composition and ±10ppm/°C temperature coefficient ensure consistent performance across the -55°C to 155°C operating range.

Frequently Asked Questions (FAQ)

Q: Can RN73C2A7K68BTDF be used as a direct replacement for 1676438-5 in circuit design?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value (7.68 kOhms), tolerance (±0.1%), power rating (0.1W), composition (thin film), package (0805), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C ~ 155°C). The only difference is packaging format.

Q: What is the difference between the packaging formats?

A: The main part 1676438-5 uses standard packaging suitable for manual handling and small-quantity applications. The substitute RN73C2A7K68BTDF uses Tape & Reel (TR) format, which is optimized for automated assembly equipment and high-volume production runs.

Q: Are both parts compatible with the same PCB footprint?

A: Yes. Both parts use the 0805 (2012 Metric) package with identical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum seated height (0.026" / 0.65mm). They are footprint-compatible and interchangeable at the PCB level.

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

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly processes.

Q: Does the substitute part offer better regulatory compliance?

A: The substitute RN73C2A7K68BTDF provides explicit ROHS3 compliance certification and REACH Unaffected status. The main part 1676438-5 lists these as "Not applicable" and "Vendor Undefined" respectively. If regulatory documentation clarity is required, the substitute part provides definitive compliance statements.

Q: Are there any thermal performance differences between these parts?

A: No. Both parts have identical power ratings (0.1W), temperature coefficients (±10ppm/°C), and operating temperature ranges (-55°C ~ 155°C). Thermal performance is equivalent.

Q: Can these parts be used interchangeably in automated assembly?

A: The substitute RN73C2A7K68BTDF in Tape & Reel format is optimized for automated pick-and-place assembly. The main part 1676438-5 in standard packaging is suitable for manual assembly or lower-volume processes. Selection depends on assembly method requirements.
