Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1676235-5 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 1.54 kOhms (exact match required)
• Tolerance: ±0.1% (precision specification)
• Power Rating: 0.1W / 1/10W (thermal capability)
• Composition: Thin Film (performance characteristics)
• Package Type: 0805 (2012 Metric) (physical and electrical footprint)
• Temperature Coefficient: ±10ppm/°C (temperature stability)
• Operating Temperature Range: -55°C ~ 155°C (environmental limits)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage)

Substitute parts must match all parameters listed above to ensure functional and mechanical compatibility within the original design.

Parameter Comparison

Engineering Selection Recommendations

Both the 1676235-5 and RN73C2A1K54BTDF are Active status products from TE Connectivity's RN73 Holsworthy series. The components are electrically and mechanically identical across all critical parameters including resistance value, tolerance, power rating, package dimensions, and operating temperature range.

The primary distinction between these parts is packaging format: the 1676235-5 is supplied in bulk packaging, while the RN73C2A1K54BTDF is supplied in Tape & Reel (TR) format. The RN73C2A1K54BTDF carries ROHS3 compliance certification, whereas the 1676235-5 RoHS status is listed as not applicable.

Selection between these parts should be based on procurement requirements, assembly process compatibility with tape and reel handling equipment, and regulatory compliance mandates for the end application.

Frequently Asked Questions (FAQ)

Q: Can RN73C2A1K54BTDF be used as a direct replacement for 1676235-5 in circuit design?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical resistance value (1.54 kOhms), tolerance (±0.1%), power rating (0.1W), package type (0805), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C ~ 155°C).

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

A: The primary differences are packaging format and RoHS certification status. The 1676235-5 uses bulk packaging, while RN73C2A1K54BTDF uses Tape & Reel (TR) format. The RN73C2A1K54BTDF is ROHS3 compliant; the 1676235-5 RoHS status is not applicable.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions of 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 the same PCB footprint.

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

A: The RN73C2A1K54BTDF in Tape & Reel format is suitable for automated assembly processes. The 1676235-5 in bulk packaging may be appropriate for lower-volume or manual assembly operations.

Q: Do these parts have the same moisture sensitivity requirements?

A: Yes. Both parts have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture handling or baking requirements.

Q: Are there any temperature-related performance differences?

A: No. Both parts operate across the identical temperature range of -55°C ~ 155°C with the same temperature coefficient of ±10ppm/°C, ensuring equivalent performance across all operating conditions.
