Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN732ATTD8563F25 is determined by the following critical parameters:

Primary Matching Criteria:

• Resistance value: 856 kOhms (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Secondary Compatibility Criteria:

• Tolerance: ±1% or tighter (equal or superior)
• Power rating: 0.1W or higher (equal or superior)
• Moisture resistance: Required feature
• Moisture Sensitivity Level: 1 (Unlimited) or equivalent

Substitute parts must maintain compatibility across all primary criteria. Secondary criteria allow for equal or superior specifications. Parts are classified as direct equivalents or upgrades based on tolerance and power rating improvements.

Engineering Selection Recommendations

RN73R2ATTD8563F25 (Direct Equivalent - Recommended for RoHS3 Compliant Applications)

The RN73R2ATTD8563F25 serves as the primary direct equivalent to the obsolete RN732ATTD8563F25. Both components share identical resistance value, tolerance, package format, composition, temperature coefficient, and operating temperature range. The RN73R2ATTD8563F25 offers a higher power rating (0.125W versus 0.1W), providing superior thermal headroom in the same physical footprint. This part maintains ROHS3 compliance and carries active product status from KOA Speer Electronics, Inc. The addition of Automotive AEC-Q200 qualification provides enhanced reliability documentation suitable for demanding applications. Footprint compatibility is confirmed with identical dimensions and height specifications.

PHP00805E8563BBT1 (Upgrade - For Enhanced Precision and Power Requirements)

The PHP00805E8563BBT1 represents an upgrade option when superior tolerance and power dissipation capacity are required. This Vishay Dale component maintains all primary matching criteria while delivering ±0.1% tolerance (tighter than the ±1% specification) and significantly higher power rating (0.63W). The component includes flame-proof and safety certifications. Physical dimensions show minor variations (0.080" L x 0.050" W versus 0.079" L x 0.049" W) and increased height (0.033" versus 0.024"), requiring verification of PCB layout constraints. This part carries RoHS non-compliant status, necessitating compliance assessment for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD8563F25 directly replace RN732ATTD8563F25 without circuit modification?

A: Yes. Both components share identical electrical specifications (856 kOhms ±1%, ±25ppm/°C, -55°C to 155°C) and physical package format (0805). The RN73R2ATTD8563F25 provides equal or superior performance with higher power rating (0.125W versus 0.1W) and identical footprint dimensions. No circuit modification is required.

Q: What are the key differences between the direct equivalent and upgrade options?

A: The RN73R2ATTD8563F25 maintains specification parity with the original part while offering active product status and higher power rating. The PHP00805E8563BBT1 upgrade provides superior tolerance (±0.1% versus ±1%) and significantly higher power capacity (0.63W versus 0.1W), but introduces minor physical dimension variations and RoHS non-compliance status.

Q: Are there physical footprint compatibility concerns with the PHP00805E8563BBT1 upgrade?

A: The PHP00805E8563BBT1 shows minor dimensional variations: length 0.080" versus 0.079", width 0.050" versus 0.049", and height 0.033" versus 0.024". These differences fall within standard 0805 package tolerance ranges but require PCB layout verification, particularly for height-constrained applications or high-density assemblies.

Q: Which substitute part should be selected for RoHS3 compliant applications?

A: The RN73R2ATTD8563F25 maintains ROHS3 compliance status matching the original RN732ATTD8563F25. The PHP00805E8563BBT1 carries RoHS non-compliant status and is unsuitable for regulated applications requiring RoHS3 certification.

Q: What is the moisture sensitivity classification for substitute parts?

A: Both substitute components maintain Moisture Sensitivity Level 1 (Unlimited), identical to the original part. This classification indicates no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.

Q: Can the PHP00805E8563BBT1 be used in applications requiring Automotive AEC-Q200 qualification?

A: The PHP00805E8563BBT1 does not carry Automotive AEC-Q200 certification. For automotive applications requiring this qualification, the RN73R2ATTD8563F25 is the appropriate selection, as it includes AEC-Q200 compliance.
