Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1676254-5 is determined by strict equivalence across the following parameters:

• Resistance Value: 21 kOhms
• Tolerance: ±0.1%
• Power Rating: 0.1W (1/10W)
• Composition: Thin Film
• Package Type: 0805 (2012 Metric)
• Temperature Coefficient: ±10ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Physical Dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute part maintains identical electrical performance and mechanical compatibility, differing only in packaging format (Tape & Reel versus individual unit packaging) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 1676254-5 and RN73C2A21KBTDF are Active status products from the same manufacturer and series. Selection between these parts is determined by procurement and assembly requirements rather than electrical or mechanical performance.

1676254-5 is suitable for applications requiring individual unit packaging or small quantity procurement.

RN73C2A21KBTDF is suitable for high-volume production environments utilizing automated pick-and-place assembly from Tape & Reel packaging. This part carries ROHS3 compliance certification and REACH Unaffected status, providing enhanced regulatory documentation for applications subject to environmental compliance requirements.

Both parts are electrically and mechanically interchangeable for circuit board applications. The choice between them depends on supply chain logistics, assembly process capabilities, and regulatory documentation requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can RN73C2A21KBTDF replace 1676254-5 in circuit board assembly?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value (21 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 termination configuration. The only difference is packaging format.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The 1676254-5 is supplied as individual units, while RN73C2A21KBTDF is supplied in Tape & Reel format. Additionally, RN73C2A21KBTDF carries ROHS3 compliance and REACH Unaffected certifications, whereas the 1676254-5 lists RoHS status as Not applicable and REACH status as Vendor Undefined.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.079" L x 0.049" W (2.00mm x 1.25mm) with a maximum seated height of 0.026" (0.65mm). They are fully compatible with identical PCB footprints.

Q: Which part should be selected for high-volume production?

A: RN73C2A21KBTDF in Tape & Reel packaging is optimized for automated assembly processes typical of high-volume production environments.

Q: Are there any temperature or environmental performance differences?

A: No. Both parts operate across the identical temperature range of -55°C ~ 155°C and maintain the same temperature coefficient of ±10ppm/°C. Both carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, from an electrical and mechanical standpoint. However, assembly process compatibility should be verified based on whether the production line is configured for individual unit or Tape & Reel component handling.
