Composition: Thin Film (exact match required)
Temperature Coefficient: ±25ppm/°C (exact match required)
Operating Temperature Range: -55°C ~ 155°C (exact match required)
Number of Terminations: 2 (exact match required)

Secondary Substitution Criteria (Allowable Variations):

Tolerance: ±1% or tighter (±0.5%, ±0.25%, ±0.1%)
Power Rating: 0.1W or higher (0.125W, 0.25W, 0.63W acceptable)

Engineering Selection Recommendations

Direct Substitutes (±1% Tolerance, Active Status):

RN73R2ATTD4533F25 and RT0805FRD07453KL are direct functional equivalents with identical electrical specifications and tolerance. Both are Active product status with ROHS3 compliance. RN73R2ATTD4533F25 includes Automotive AEC-Q200 qualification. RT0805FRD07453KL is manufactured by YAGEO with equivalent performance characteristics.

Upgrade Substitutes (Tighter Tolerance, Active Status, ROHS3 Compliant):

AT0805BRD07453KL, AT0805CRD07453KL, AT0805DRD07453KL, ERA-6AEB4533V, and RG2012P-4533-B-T5 provide tolerance improvements (±0.1%, ±0.25%, ±0.5%) while maintaining 0.125W power rating and 0805 package. All feature Automotive AEC-Q200 qualification except AT0805CRD07453KL and AT0805DRD07453KL. These parts are suitable for applications requiring enhanced accuracy.

Upgrade Substitute (Matched Power Rating, Tighter Tolerance, Active Status, ROHS3 Compliant):

CPF0805B453KE1 maintains the original 0.1W power rating with ±0.1% tolerance improvement. This part is optimal for designs requiring precision matching without power rating changes.

Upgrade Substitute (Higher Power Rating, Tighter Tolerance, Active Status):

PHP00805E4533BBT1 provides 0.63W power rating with ±0.1% tolerance and Flame Proof, Moisture Resistant features. RoHS non-compliant status requires verification against design requirements.

Non-Recommended Substitute (RoHS Non-Compliant):

5-2176094-6 is RoHS non-compliant and should be selected only when RoHS exemption is documented and approved.

Frequently Asked Questions (FAQ)

Q: Can I substitute RN732ATTD4533F25 with RN73R2ATTD4533F25?

A: Yes. RN73R2ATTD4533F25 is a direct substitute with identical resistance (453 kOhms), tolerance (±1%), package (0805), and thermal characteristics. The higher power rating (0.125W vs. 0.1W) and Automotive AEC-Q200 qualification provide additional design margin. Both are ROHS3 compliant.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes match the original part's tolerance (±1%) and power rating (0.1W). Upgrade substitutes offer tighter tolerance (±0.1%, ±0.25%, ±0.5%) or higher power rating (0.125W, 0.25W, 0.63W) while maintaining all other electrical and mechanical parameters. Upgrade substitutes are backward-compatible and suitable for applications requiring enhanced performance.

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

A: All substitute parts use 0805 (2012 Metric) package with identical footprint (0.079" L x 0.049" W / 2.00mm x 1.25mm). Height variations exist: standard parts measure 0.024" (0.60mm), CPF0805B453KE1 and 5-2176094-6 measure 0.026" (0.65mm), PHP00805E4533BBT1 measures 0.033" (0.84mm), and RG2012P-4533-B-T5 measures 0.020" (0.50mm). Verify clearance requirements for applications with height constraints.

Q: Which substitute parts have Automotive AEC-Q200 qualification?

A: RN73R2ATTD4533F25, AT0805BRD07453KL, AT0805CRD07453KL, AT0805DRD07453KL, ERA-6AEB4533V, and RG2012P-4533-B-T5 carry Automotive AEC-Q200 qualification. These parts are suitable for automotive and high-reliability applications.

Q: What is the impact of tolerance selection on circuit performance?

A: Tolerance determines the maximum deviation from the nominal 453 kOhms value. ±1% tolerance allows ±4.53 kOhms deviation. ±0.1% tolerance allows ±0.453 kOhms deviation. Tighter tolerance substitutes reduce circuit parameter variation and improve performance stability in precision applications. Select tolerance based on circuit sensitivity to resistance variation.

Q: Are all substitute parts ROHS3 compliant?

A: Most substitute parts are ROHS3 compliant. Exceptions are 5-2176094-6 and PHP00805E4533BBT1, which are RoHS non-compliant. Verify RoHS compliance requirements before selecting these parts.

Q: Can I use CPF0805B453KE1 as a direct replacement for RN732ATTD4533F25?

A: Yes. CPF0805B453KE1 maintains the original 0.1W power rating and 0805 package with improved ±0.1% tolerance. Both parts are ROHS3 compliant and operate across -55°C ~ 155°C. This substitution provides tolerance enhancement without design modification.

Q: What are the moisture sensitivity implications for these parts?

A: All substitute parts maintain Moisture Sensitivity Level (MSL) 1 (Unlimited), identical to the original part. This classification indicates no moisture sensitivity restrictions and no special storage or handling requirements.
