Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN732ATTD8560A10 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 856 Ohms
• Tolerance: ±0.05%
• Package format: 0805 (2012 Metric)
• Composition: Thin Film
• Termination count: 2

Allowable Variation Parameters:

• Power rating: Equal to or greater than 0.1W
• Temperature coefficient: Equal to or lower absolute value
• Operating temperature range: Equal to or exceeding -55°C to 155°C
• Features: Moisture resistance required; additional features permitted

Substitute parts must maintain electrical equivalence through identical resistance and tolerance specifications while accommodating enhanced power ratings and improved thermal performance characteristics.

Engineering Selection Recommendations

RN73R2ATTD8560A10 (Direct Substitute): This component serves as the direct equivalent replacement for the obsolete RN732ATTD8560A10. Both parts maintain identical electrical specifications (856 Ohms ±0.05%) and package format (0805). The RN73R2ATTD8560A10 offers increased power rating (0.125W versus 0.1W) and includes automotive AEC-Q200 qualification. Product status is active with current inventory availability. This substitute is suitable for applications requiring direct form-fit-function replacement with enhanced reliability certification.

PLTT0805Z8560AGT5 (Upgrade Substitute): This Vishay Dale component provides enhanced performance characteristics while maintaining core electrical equivalence. The upgrade offers doubled power rating (0.25W), improved temperature coefficient (±5ppm/°C versus ±10ppm/°C), and extended operating temperature range (-55°C to 215°C). Additional features include anti-corrosive and flame-proof construction. This substitute is appropriate for applications requiring superior thermal margin, enhanced environmental protection, or extended temperature operation within the 0805 package constraint.

Both substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) ratings consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD8560A10 directly replace RN732ATTD8560A10 in existing designs?

A: Yes. Both components share identical resistance (856 Ohms), tolerance (±0.05%), package format (0805), and operating temperature range (-55°C to 155°C). The RN73R2ATTD8560A10 provides equal or superior performance with increased power rating (0.125W) and active product status.

Q: What is the primary difference between the direct substitute and upgrade substitute?

A: The RN73R2ATTD8560A10 (direct substitute) maintains equivalent specifications with automotive qualification. The PLTT0805Z8560AGT5 (upgrade substitute) provides enhanced power rating (0.25W), superior temperature coefficient (±5ppm/°C), extended temperature range (-55°C to 215°C), and additional protective features (anti-corrosive, flame-proof).

Q: Are all substitute parts available in the same packaging format?

A: Yes. All three components utilize 0805 (2012 Metric) package format with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Physical board layout compatibility is maintained across all substitutes.

Q: Do substitute parts maintain the same moisture resistance characteristics?

A: Yes. All substitute parts include moisture-resistant construction with MSL 1 (Unlimited) rating, matching the original RN732ATTD8560A10 specification.

Q: Which substitute is recommended for high-temperature applications?

A: The PLTT0805Z8560AGT5 supports extended operating temperature to 215°C, compared to 155°C for both KOA Speer components. This upgrade substitute is suitable for applications requiring operation beyond 155°C.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All three components maintain ROHS3 compliance status, meeting environmental and regulatory requirements equivalent to the original part.
