Substitute Part Grouping Explanation

Substitution of the RP73C2B200RFTDF is permissible with the TNPW1206200RBYEN based on the following alignment of critical parameters:

Electrical Equivalence:

• Identical resistance value: 200 Ohms
• Compatible package designation: 1206 (3216 Metric)
• Matching composition: Thin Film
• Identical temperature coefficient: ±10ppm/°C
• Identical number of terminations: 2

Mechanical Compatibility:

• Identical package footprint and supplier device package classification
• Height specifications within acceptable tolerance range (0.026" maximum seated height for both)
• Identical Moisture Sensitivity Level: 1 (Unlimited)

Substitution Criteria: The TNPW1206200RBYEN qualifies as a substitute because it maintains all core electrical parameters while offering enhanced tolerance (±0.1% versus ±1%), increased power rating (0.52W versus 0.25W), extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C), and improved regulatory compliance (RoHS3 Compliant versus RoHS non-compliant).

Engineering Selection Recommendations

RP73C2B200RFTDF Selection Criteria: Select the RP73C2B200RFTDF when the application requires the original TE Connectivity Passive Product specification, legacy design compliance, or when RoHS non-compliant components are explicitly required by design documentation.

TNPW1206200RBYEN Selection Criteria: Select the TNPW1206200RBYEN when the application benefits from enhanced tolerance specification (±0.1%), increased power dissipation capability (0.52W), extended operating temperature range to 175°C, RoHS3 compliance, or automotive-grade reliability (AEC-Q200 certification). The TNPW1206200RBYEN provides anti-sulfur and moisture-resistant characteristics suitable for harsh environmental applications.

Both components maintain identical mechanical footprint compatibility and core electrical parameters, enabling direct substitution in 1206 package applications without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the TNPW1206200RBYEN directly replace the RP73C2B200RFTDF on existing PCBs?

A: Yes. Both components share identical 1206 (3216 Metric) package specifications, footprint dimensions, and termination count. No PCB layout modifications are required for mechanical or electrical compatibility.

Q: What is the significance of the tolerance difference between ±1% and ±0.1%?

A: Tolerance defines the acceptable resistance value deviation from the nominal 200 Ohm specification. The RP73C2B200RFTDF permits ±1% deviation (198–202 Ohms), while the TNPW1206200RBYEN permits ±0.1% deviation (199.8–200.2 Ohms). Applications requiring tighter resistance accuracy benefit from the substitute part's enhanced tolerance.

Q: Are there thermal performance differences between these components?

A: The TNPW1206200RBYEN has a higher power rating (0.52W versus 0.25W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). Applications operating at elevated temperatures or requiring higher power dissipation capacity benefit from the substitute specification.

Q: What does AEC-Q200 certification indicate?

A: AEC-Q200 is an automotive-grade reliability standard. The TNPW1206200RBYEN carries this certification, indicating qualification for automotive applications with enhanced reliability and environmental stress testing requirements.

Q: Is the height difference between components significant?

A: Both components have identical maximum seated height of 0.026" (0.65mm). No height-related clearance issues exist between the main part and substitute.

Q: What is the impact of RoHS compliance status?

A: The RP73C2B200RFTDF is RoHS non-compliant, while the TNPW1206200RBYEN is RoHS3 compliant. Applications subject to RoHS regulations or customer requirements for lead-free, restricted substance compliance require the substitute part.

Q: Can both components be used interchangeably in the same design?

A: Yes, provided the application does not have conflicting requirements regarding RoHS compliance, tolerance specification, power rating, or operating temperature range. The substitute part's enhanced specifications make it suitable for applications where the main part meets minimum requirements.
