Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD7233F25 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Resistance Value: 723 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• Number of Terminations: 2

Allowable Variation Parameters:

• Tolerance: May be equal to or tighter than ±1%
• Power Rating: May be equal to or greater than 0.1W
• Product Status: Active status preferred for ongoing availability

All substitute parts listed maintain identical resistance value, package format, and thermal characteristics. Variations in tolerance and power rating represent upgrades or equivalent specifications suitable for direct substitution in circuit applications.

Engineering Selection Recommendations

RN73R2ATTD7233F25 (Direct Substitute - Recommended for Standard Applications)

This part represents the primary direct substitute for the obsolete RN732ATTD7233F25. It maintains identical electrical specifications (723 kOhms, ±1% tolerance, ±25ppm/°C temperature coefficient) and package format (0805). The power rating increases from 0.1W to 0.125W, providing additional thermal margin without altering circuit behavior. The part carries Active product status and ROHS3 compliance. Automotive AEC-Q200 qualification provides enhanced reliability documentation. This substitute is suitable for direct replacement in all applications where the original part was specified.

PHP00805E7233BBT1 (Upgrade Substitute - High-Precision Applications)

This Vishay Dale component offers superior tolerance specification (±0.1% versus ±1%), making it suitable for precision measurement and calibration circuits requiring tighter resistance accuracy. The significantly higher power rating (0.63W) accommodates applications with elevated power dissipation requirements. Flame-proof and safety-rated construction provide additional protection features. Note that this part carries RoHS non-compliant status, which may restrict use in regulated markets or applications with RoHS requirements. Physical dimensions show minor variation (height 0.033" versus 0.024"), requiring verification of PCB layout clearance.

RT0805BRD07723KL (Upgrade Substitute - Precision with RoHS Compliance)

This YAGEO component combines the precision tolerance advantage (±0.1%) with ROHS3 compliance and Active product status. Power rating matches the direct substitute at 0.125W. Physical dimensions remain identical to the main part. This option is optimal for applications requiring both precision specifications and regulatory compliance without the RoHS exception required by the Vishay alternative.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD7233F25 be used as a direct replacement for RN732ATTD7233F25?

A: Yes. Both parts share identical resistance value (723 kOhms), tolerance (±1%), package format (0805), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C to 155°C). The power rating increase from 0.1W to 0.125W is a non-limiting upgrade. The RN73R2ATTD7233F25 is Active status and suitable for direct PCB substitution.

Q: What is the difference between the tolerance specifications of the substitute parts?

A: The main part and RN73R2ATTD7233F25 specify ±1% tolerance. The PHP00805E7233BBT1 and RT0805BRD07723KL both specify ±0.1% tolerance. Tighter tolerance (±0.1%) represents improved accuracy and is suitable for precision applications. In circuits where ±1% tolerance is acceptable, the tighter tolerance substitutes provide equivalent or superior performance.

Q: Are all substitute parts available in the same 0805 package?

A: Yes. All substitute parts use the 0805 (2012 Metric) package format. Physical dimensions are nominally identical, with minor variations in maximum seated height (0.024" for most parts, 0.033" for PHP00805E7233BBT1). PCB footprints designed for 0805 components accommodate all listed substitutes.

Q: Which substitute part should be selected for automotive applications?

A: The RN73R2ATTD7233F25 carries AEC-Q200 automotive qualification, making it the specified choice for automotive circuit designs. The other substitutes do not carry explicit automotive ratings in the provided specifications.

Q: What is the impact of RoHS compliance status on part selection?

A: The RN732ATTD7233F25, RN73R2ATTD7233F25, and RT0805BRD07723KL are ROHS3 compliant. The PHP00805E7233BBT1 is RoHS non-compliant. Selection depends on regulatory requirements of the end application. RoHS-regulated markets and applications require selection of compliant alternatives.

Q: Can the higher power-rated PHP00805E7233BBT1 be used in place of the 0.1W main part?

A: Yes. The 0.63W rating of PHP00805E7233BBT1 is a non-limiting upgrade. Higher power rating indicates greater thermal capacity and does not degrade performance in circuits designed for lower power dissipation. Physical dimension variation (height 0.033" versus 0.024") requires PCB layout verification for clearance compatibility.

Q: Are there any temperature coefficient differences among the substitute parts?

A: No. All parts, including the main component and all substitutes, specify identical temperature coefficient of ±25ppm/°C and identical operating temperature range of -55°C to 155°C. Thermal performance characteristics are equivalent across all listed parts.
