Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TNPW08051M00BETY are qualified based on the following criteria:

Electrical Compatibility: Resistance value of 1 MOhms with ±0.1% tolerance, power rating of 0.125W (1/8W), thin film composition, and temperature coefficient of ±25ppm/°C.

Mechanical Compatibility: 0805 (2012 Metric) package with 2 terminations, identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm).

Environmental Specifications: Operating temperature range of -55°C to 125°C or higher, Moisture Sensitivity Level 1 (Unlimited).

Packaging: Tape & Reel (TR) format for automated assembly compatibility.

The following parts meet these criteria and are classified as direct substitutes:

• RP73F2A1M0BTDF (TE Connectivity Passive Product): Direct equivalent with extended operating temperature to 155°C and RoHS3 compliance.
• MCU08050D1004BP100 (Vishay Beyschlag/Draloric/BC Components): Direct equivalent with anti-sulfur thin film composition and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

TNPW08051M00BETY (Primary Part): Suitable for applications where military-grade thin film composition is specified. Note that this part is RoHS non-compliant and REACH Affected, which may restrict use in regulated markets or applications with environmental compliance requirements.

RP73F2A1M0BTDF (Substitute - Extended Temperature Range): Recommended for applications requiring operation above 125°C, up to 155°C. This part is RoHS3 compliant, supporting compliance with modern environmental regulations. Seated height is 0.026" (0.65mm) compared to 0.022" (0.55mm) for the primary part; verify clearance in space-constrained designs.

MCU08050D1004BP100 (Substitute - Anti-Sulfur Composition): Recommended for applications in corrosive or high-sulfur environments due to anti-sulfur thin film composition. This part is RoHS3 compliant and REACH Unaffected, providing full environmental compliance. Seated height matches the primary part at 0.022" (0.55mm).

All three parts share identical electrical specifications (1 MOhm ±0.1%, 0.125W, ±25ppm/°C) and mechanical footprint (0805 package, 2.00mm x 1.25mm), ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can RP73F2A1M0BTDF be used as a direct replacement for TNPW08051M00BETY?

A: Yes, electrically and mechanically. Both parts have identical resistance (1 MOhm ±0.1%), power rating (0.125W), temperature coefficient (±25ppm/°C), and 0805 package footprint. The RP73F2A1M0BTDF has an extended operating temperature range (-55°C to 155°C versus -55°C to 125°C) and is RoHS3 compliant. The seated height difference (0.026" vs 0.022") must be verified for PCB clearance in height-restricted applications.

Q: What is the difference between the TNPW08051M00BETY and MCU08050D1004BP100?

A: Both parts are electrically identical (1 MOhm ±0.1%, 0.125W, ±25ppm/°C) and mechanically compatible (0805 package). The MCU08050D1004BP100 features anti-sulfur thin film composition, making it suitable for corrosive environments. The MCU08050D1004BP100 is RoHS3 compliant and REACH Unaffected, while the TNPW08051M00BETY is RoHS non-compliant and REACH Affected.

Q: Are all three parts compatible with the same PCB layout?

A: Yes, all three parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W). The seated height of RP73F2A1M0BTDF is 0.026" (0.65mm) compared to 0.022" (0.55mm) for the other two parts. Verify clearance for components or structures above the resistor in space-constrained designs.

Q: Which substitute part should be selected for new designs?

A: Selection depends on application requirements. For extended temperature operation above 125°C, use RP73F2A1M0BTDF. For corrosive or high-sulfur environments, use MCU08050D1004BP100. Both substitute parts are RoHS3 compliant, supporting modern environmental and regulatory requirements. The TNPW08051M00BETY is suitable only for applications where military-grade composition is explicitly required and RoHS non-compliance is acceptable.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All three parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Are these parts available in other package formats?

A: The specifications provided cover only the 0805 (2012 Metric) package format. Other package options, if available, would be listed separately with distinct part numbers.
