Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1676342-5 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part RN73C2A442RBTDF maintains identical specifications in the following key areas:

• Resistance value: 442 Ohms
• Tolerance specification: ±0.1%
• Power rating: 0.1W (1/10W)
• Package format: 0805 (2012 Metric)
• Thin film composition
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Physical dimensions and height
• Number of terminations: 2
• Moisture sensitivity level: 1 (Unlimited)

The primary difference between the main part and substitute is the packaging format: the main part uses standard packaging while the substitute is supplied in Tape & Reel (TR) format. Both parts are manufactured by TE Connectivity Passive Product and belong to the RN73 Holsworthy series.

Parameter Comparison

Engineering Selection Recommendations

Both the main part 1676342-5 and substitute part RN73C2A442RBTDF are Active status components manufactured by TE Connectivity Passive Product. The substitute part RN73C2A442RBTDF offers ROHS3 compliance, which may be required for applications subject to regulatory restrictions on hazardous substances.

Selection between these parts should be based on:

1. Packaging Requirements: The main part uses standard packaging, while the substitute is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and high-volume production environments.

2. Regulatory Compliance: The substitute part carries explicit ROHS3 compliance certification, whereas the main part lists RoHS status as "Not applicable." Applications requiring documented RoHS compliance should utilize the substitute part.

3. Supply Chain Availability: The substitute part RN73C2A442RBTDF maintains higher inventory levels (3445 Pcs) compared to the main part (779 Pcs), providing improved availability for procurement planning.

Both parts are electrically and mechanically identical, ensuring direct substitution without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can RN73C2A442RBTDF be used as a direct replacement for 1676342-5 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including resistance value, tolerance, power rating, package dimensions, and operating temperature range. The primary difference is packaging format (Tape & Reel versus standard packaging).

Q: What is the significance of the Tape & Reel (TR) packaging format?

A: Tape & Reel packaging is the standard format for automated surface mount assembly. Components are wound on continuous tape with carrier tape, enabling high-speed pick-and-place machine processing. This format is required for volume production and is compatible with standard SMD assembly equipment.

Q: Does the substitute part RN73C2A442RBTDF meet RoHS requirements?

A: Yes. The substitute part carries ROHS3 compliance certification. The main part lists RoHS status as "Not applicable." For applications requiring documented RoHS compliance, the substitute part is the appropriate selection.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts share identical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) with maximum seated height of 0.026" (0.65mm). Both use the 0805 (2012 Metric) package format and are mechanically interchangeable on PCB layouts.

Q: What is the temperature coefficient specification and its application?

A: Both parts specify ±10ppm/°C temperature coefficient. This parameter defines the resistance change per degree Celsius across the operating temperature range of -55°C to 155°C. The tight ±0.1% tolerance combined with low temperature coefficient makes these components suitable for precision measurement and analog signal conditioning applications.

Q: Is the Moisture Sensitivity Level (MSL) rating the same for both parts?

A: Yes. Both parts carry MSL rating of 1 (Unlimited), indicating unlimited shelf life without moisture bake-out requirements prior to soldering. This simplifies component storage and handling procedures.

Q: What does the thin film composition indicate about component performance?

A: Thin film resistors provide superior tolerance accuracy (±0.1% in this case), low temperature coefficient (±10ppm/°C), and excellent frequency response characteristics compared to thick film alternatives. These properties make thin film resistors the standard choice for precision analog circuits, measurement instrumentation, and high-frequency applications.
