Substitute Part Grouping Explanation

Substitution of the main part number 1676285-5 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute parts RN73C2A2K21BTD and RN73C2A2K21BTDF maintain identical specifications for resistance value, tolerance, power rating, composition, package type, temperature coefficient, operating temperature range, physical dimensions, and termination count. The primary differences between substitute parts relate to packaging format (Tape & Reel) and regulatory compliance certifications (RoHS status and REACH classification). All three parts belong to the same RN73 series from TE Connectivity Passive Product and are classified as Active product status.

Parameter Comparison

Engineering Selection Recommendations

All three parts are electrically and mechanically equivalent and suitable for direct substitution in applications requiring a 2.21 kOhms ±0.1% thin film resistor in 0805 package format. Selection between substitute parts should be based on regulatory compliance requirements and packaging format needs.

RN73C2A2K21BTDF is the appropriate selection for applications subject to ROHS3 compliance requirements and REACH regulations. This part carries ROHS3 Compliant status and REACH Unaffected classification, making it suitable for European market applications and regulated industries.

RN73C2A2K21BTD is suitable for applications where RoHS compliance is not a requirement. This part is RoHS non-compliant and carries Vendor Undefined REACH status.

Both substitute parts are supplied in Tape & Reel (TR) packaging format, which differs from the main part number 1676285-5 packaging specification. Tape & Reel format is standard for automated assembly processes and high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts electrically identical to the main part 1676285-5?

A: Yes. RN73C2A2K21BTD and RN73C2A2K21BTDF maintain identical electrical specifications including 2.21 kOhms resistance, ±0.1% tolerance, 0.1W power rating, ±10ppm/°C temperature coefficient, and -55°C ~ 155°C operating temperature range.

Q: Are the substitute parts mechanically compatible with the main part?

A: Yes. All three parts use identical 0805 (2012 Metric) package format with matching physical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.026" (0.65mm). Both substitute parts have 2 terminations identical to the main part.

Q: What is the difference between RN73C2A2K21BTD and RN73C2A2K21BTDF?

A: The primary differences are regulatory compliance certifications. RN73C2A2K21BTDF is ROHS3 Compliant and REACH Unaffected, while RN73C2A2K21BTD is RoHS non-compliant with Vendor Undefined REACH status. Both parts are supplied in Tape & Reel packaging.

Q: Can I use these substitute parts in my existing PCB design without layout modifications?

A: Yes. The substitute parts are mechanically and electrically equivalent to the main part 1676285-5 and require no PCB layout modifications. The 0805 package footprint remains identical across all three parts.

Q: What packaging format do the substitute parts use?

A: Both substitute parts RN73C2A2K21BTD and RN73C2A2K21BTDF are supplied in Tape & Reel (TR) format, which is standard for automated pick-and-place assembly processes.

Q: Which substitute part should I select for RoHS-compliant applications?

A: RN73C2A2K21BTDF is ROHS3 Compliant and is the appropriate selection for applications requiring RoHS compliance.

Q: Are all three parts from the same manufacturer?

A: Yes. The main part 1676285-5 and both substitute parts RN73C2A2K21BTD and RN73C2A2K21BTDF are manufactured by TE Connectivity Passive Product and belong to the RN73 series from Holsworthy.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have Moisture Sensitivity Level (MSL) 1, which indicates Unlimited moisture sensitivity classification. These parts do not require special moisture control during storage or handling.
