Key Parameters

Substitute Part Grouping Explanation

Substitution for the RN732ATTD2002F25 is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 20 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Operating Temperature Range: minimum -55°C ~ 155°C (equal or wider range acceptable)

Secondary Substitution Criteria (Allowable Variations):

• Tolerance: ±1% or tighter (±0.1% acceptable as upgrade)
• Power Rating: 0.1W or higher (0.125W, 0.26W acceptable as upgrades)
• Manufacturer: Different manufacturers acceptable if all primary criteria met
• Product Status: Active preferred over obsolete
• Compliance: ROHS3 Compliant or equivalent regulatory status

The RN73R2ATTD2002F25 qualifies as a direct equivalent with identical electrical specifications and higher power rating. The TNPW080520K0BETA qualifies as an upgrade substitute with tighter tolerance and higher power rating. The TNPW08052K00BEEA does not qualify as a substitute due to resistance value mismatch (2 kOhms vs. 20 kOhms required).

Engineering Selection Recommendations

RN73R2ATTD2002F25 (Direct Equivalent - Recommended Primary Choice)

The RN73R2ATTD2002F25 is the recommended direct substitute for the obsolete RN732ATTD2002F25. This part maintains identical electrical specifications (20 kOhms ±1%, ±25ppm/°C temperature coefficient) and package configuration (0805 thin film). The RN73R2ATTD2002F25 offers higher power rating (0.125W vs. 0.1W), providing additional thermal margin. Product status is active with ROHS3 compliance maintained. Automotive AEC-Q200 qualification provides enhanced reliability documentation. Inventory availability is confirmed at 825 pieces.

TNPW080520K0BETA (Upgrade Substitute - Secondary Choice)

The TNPW080520K0BETA qualifies as an upgrade substitute with tighter tolerance specification (±0.1% vs. ±1%) and military-grade construction. Electrical parameters match the main part (20 kOhms, ±25ppm/°C, 0805 package). Power rating is 0.125W, exceeding the original 0.1W requirement. Operating temperature range is -55°C ~ 125°C, which is narrower than the original -55°C ~ 155°C specification. RoHS non-compliance status requires verification against design requirements. This part is suitable for applications requiring tighter tolerance and military specifications where the reduced upper temperature limit is acceptable.

TNPW08052K00BEEA (Not Suitable)

The TNPW08052K00BEEA does not qualify as a substitute. The resistance value is 2 kOhms, which does not match the required 20 kOhms specification. This part is listed in the provided data but is electrically incompatible with the original design requirement.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD2002F25 be used as a direct replacement for RN732ATTD2002F25?

A: Yes. The RN73R2ATTD2002F25 maintains identical resistance (20 kOhms), tolerance (±1%), temperature coefficient (±25ppm/°C), and package (0805 thin film). The higher power rating (0.125W vs. 0.1W) is a beneficial upgrade. Both parts operate across -55°C ~ 155°C. Physical dimensions and termination count are identical.

Q: What is the difference between the main part and RN73R2ATTD2002F25?

A: The primary differences are product status (obsolete vs. active), power rating (0.1W vs. 0.125W), and certifications. RN73R2ATTD2002F25 includes Automotive AEC-Q200 qualification and is available in Tape & Reel packaging. Electrical performance is equivalent.

Q: Is TNPW080520K0BETA suitable for all applications using RN732ATTD2002F25?

A: TNPW080520K0BETA is suitable for applications where the operating temperature range does not exceed 125°C. The original part specification extends to 155°C. If your application requires operation above 125°C, this substitute is not appropriate. The tighter tolerance (±0.1%) and military specifications make this part suitable for precision applications within the supported temperature range.

Q: Why is TNPW08052K00BEEA listed as a substitute if the resistance value differs?

A: TNPW08052K00BEEA (2 kOhms) is not a valid substitute for the 20 kOhms requirement. This part appears in the provided data but does not meet the primary substitution criterion of matching resistance value. It should not be selected for this application.

Q: What packaging options are available for substitute parts?

A: RN73R2ATTD2002F25 is available in Tape & Reel (TR) packaging. TNPW080520K0BETA is available in Tape & Reel (TR) packaging. Both substitute parts maintain the 0805 (2012 Metric) package / case specification matching the original part.

Q: Are there compliance differences between the main part and substitutes?

A: RN732ATTD2002F25 and RN73R2ATTD2002F25 are both ROHS3 Compliant and REACH Unaffected. TNPW080520K0BETA is RoHS non-compliant and REACH Affected. Design requirements must specify acceptable compliance status before selecting TNPW080520K0BETA.

Q: What is the inventory status for substitute parts?

A: RN73R2ATTD2002F25 has 825 pieces in stock. TNPW080520K0BETA has 881 pieces in stock. Both parts are available for immediate procurement.
