Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1676405-5 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance Value: 66.5 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Power Rating: 0.1W / 1/10W (exact match required)
• Package Type: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±10ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Physical Dimensions: 0.079" L x 0.049" W / 2.00mm x 1.25mm (exact match required)

The identified substitute part RN73C2A66K5BTDF meets all electrical and mechanical specifications. The primary distinction between the main part and substitute is the packaging configuration: the main part number 1676405-5 is supplied in standard packaging, while RN73C2A66K5BTDF is supplied in Tape & Reel (TR) format. Both parts are manufactured by TE Connectivity Passive Product within the RN73 series.

Parameter Comparison

Engineering Selection Recommendations

Both the main part number 1676405-5 and the substitute RN73C2A66K5BTDF are Active products manufactured by TE Connectivity Passive Product. Selection between these parts is based on procurement and assembly requirements rather than electrical or mechanical performance differences.

1676405-5 is appropriate for applications requiring standard packaging configurations and when RoHS compliance status is not a constraint.

RN73C2A66K5BTDF is appropriate for applications requiring ROHS3 compliance and Tape & Reel packaging for automated assembly processes. This part carries explicit ROHS3 Compliant certification and REACH Unaffected status, providing enhanced regulatory documentation for applications subject to these compliance frameworks.

Both parts operate identically within the specified electrical and thermal parameters and are mechanically interchangeable in 0805 surface mount applications.

Frequently Asked Questions (FAQ)

Q: Are the 1676405-5 and RN73C2A66K5BTDF electrically identical?

A: Yes. Both parts deliver 66.5 kOhms ±0.1% resistance with 0.1W power rating, ±10ppm/°C temperature coefficient, and -55°C to 155°C operating range. Electrical performance is identical.

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

A: The primary difference is packaging format. The 1676405-5 uses standard packaging, while RN73C2A66K5BTDF is supplied in Tape & Reel (TR) format. Additionally, RN73C2A66K5BTDF carries explicit ROHS3 Compliant and REACH Unaffected certifications.

Q: Can RN73C2A66K5BTDF be used as a direct replacement for 1676405-5 in PCB assembly?

A: Yes. Both parts are mechanically and electrically equivalent in 0805 (2012 Metric) surface mount applications. The component footprint, solder pad configuration, and electrical behavior are identical.
