Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1676351-5 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 48.7 kOhms (exact match required)
• Tolerance: ±0.1% (precision specification)
• Power Rating: 0.1W / 1/10W (thermal capability)
• Composition: Thin Film (performance characteristics)
• Package / Case: 0805 (2012 Metric) (physical footprint and PCB compatibility)
• Temperature Coefficient: ±10ppm/°C (temperature stability)
• Operating Temperature Range: -55°C ~ 155°C (environmental limits)
• Termination Count: 2 (electrical connectivity)

Substitute parts must match all electrical specifications and physical dimensions to ensure direct replacement without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

The RN73C2A48K7BTDF substitute part is electrically and mechanically equivalent to the 1676351-5 across all critical performance parameters. Both components are manufactured by TE Connectivity within the RN73 Holsworthy series and maintain Active product status.

The primary distinction between these parts is packaging format: the 1676351-5 is supplied in bulk packaging, while the RN73C2A48K7BTDF is supplied in Tape & Reel (TR) format. This difference accommodates different procurement and assembly workflows without affecting component performance or PCB integration.

The RN73C2A48K7BTDF carries ROHS3 compliance certification and REACH Unaffected status, providing enhanced regulatory documentation compared to the main part number. Both components share identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications.

Selection between these parts should be based on packaging requirements and supply chain availability rather than electrical or mechanical considerations.

Frequently Asked Questions (FAQ)

Q: Can the RN73C2A48K7BTDF be used as a direct replacement for the 1676351-5?

A: Yes. Both parts are electrically and mechanically identical with matching resistance (48.7 kOhms), tolerance (±0.1%), power rating (0.1W), package (0805), and all thermal specifications. The only difference is packaging format (Tape & Reel versus bulk).

Q: What is the difference between the 1676351-5 and RN73C2A48K7BTDF?

A: The parts are functionally equivalent. The 1676351-5 uses bulk packaging, while the RN73C2A48K7BTDF uses Tape & Reel (TR) packaging. The RN73C2A48K7BTDF also carries explicit ROHS3 compliance and REACH Unaffected certifications.

Q: Are there any PCB layout or footprint differences between these parts?

A: No. Both components 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). PCB footprints are interchangeable.

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

A: The RN73C2A48K7BTDF in Tape & Reel format is standard for automated assembly processes. The 1676351-5 in bulk packaging is suitable for lower-volume or manual assembly applications.

Q: Do these parts have different temperature operating ranges?

A: No. Both parts operate across the identical temperature range of -55°C to 155°C with matching temperature coefficient of ±10ppm/°C.

Q: Are moisture sensitivity requirements the same for both parts?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
