Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1676356-5 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part RN73C2A4K22BTDF maintains identical specifications for resistance value, tolerance, power rating, composition type, package form factor, temperature coefficient, and operating temperature range. Both parts are manufactured by TE Connectivity within the RN73 series and share the same 0805 (2012 Metric) package dimensions and termination configuration.

The primary distinction between the main part and the substitute is the packaging format: the 1676356-5 is supplied in standard packaging, while the RN73C2A4K22BTDF is supplied in Tape & Reel (TR) format. This difference accommodates different manufacturing and assembly workflows without affecting the electrical or mechanical performance of the component.

Substitution eligibility is based on the following parameters:

• Resistance value: 4.22 kOhms
• Tolerance: ±0.1%
• Power rating: 0.1W (1/10W)
• Composition: Thin Film
• Package / Case: 0805 (2012 Metric)
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C to 155°C
• Physical dimensions and termination count

Engineering Selection Recommendations

Both the TE Connectivity 1676356-5 and RN73C2A4K22BTDF are active products manufactured by TE Connectivity and are electrically and mechanically equivalent. Selection between these parts should be based on packaging and compliance requirements specific to the application.

The RN73C2A4K22BTDF offers ROHS3 compliance and REACH Unaffected status, making it suitable for applications with regulatory requirements for hazardous substance restrictions. The 1676356-5 carries a "Not applicable" RoHS status and "Vendor Undefined" REACH status, which may limit its use in regulated environments.

For high-volume manufacturing operations requiring automated assembly, the Tape & Reel (TR) packaging format of the RN73C2A4K22BTDF provides advantages in pick-and-place efficiency and component handling. Standard packaging of the 1676356-5 may be preferred for lower-volume applications or manual assembly workflows.

Both parts share identical electrical performance characteristics, physical dimensions, and thermal operating ranges, ensuring direct functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the RN73C2A4K22BTDF be used as a direct replacement for the 1676356-5?

A: Yes. Both parts are electrically and mechanically equivalent, with identical resistance values, tolerances, power ratings, package dimensions, and operating temperature ranges. The primary difference is packaging format: the RN73C2A4K22BTDF is supplied in Tape & Reel format, while the 1676356-5 is supplied in standard packaging.

Q: What is the difference between standard packaging and Tape & Reel (TR) packaging?

A: Tape & Reel packaging supplies components wound on a continuous tape within a reel, optimized for automated pick-and-place assembly equipment. Standard packaging typically refers to alternative formats such as bulk or tube packaging. Both formats contain identical components with no electrical or mechanical differences.

Q: Are there any compliance differences between these parts?

A: The RN73C2A4K22BTDF is ROHS3 compliant and REACH Unaffected. The 1676356-5 has "Not applicable" RoHS status and "Vendor Undefined" REACH status. Applications subject to hazardous substance restrictions should use the RN73C2A4K22BTDF.

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

A: Yes. Both the 1676356-5 and RN73C2A4K22BTDF have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.

Q: What are the physical dimensions of the 0805 package?

A: The 0805 (2012 Metric) package measures 0.079" length by 0.049" width (2.00mm x 1.25mm), with a maximum seated height of 0.026" (0.65mm).

Q: Can these parts be used in temperature-critical applications?

A: Both parts operate across -55°C to 155°C with a temperature coefficient of ±10ppm/°C, making them suitable for wide temperature range applications. The thin film composition provides stable resistance performance across this operating range.

Q: Are both parts currently in active production?

A: Yes. Both the 1676356-5 and RN73C2A4K22BTDF maintain active product status with TE Connectivity.
