Substitute Part Grouping Explanation

Substitute parts for the RN732ATTD1002F25 are classified based on the following substitution criteria:

Core Compatibility Parameters:

• Resistance value: 10 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)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variations:

• Tolerance: ±1% or tighter (±0.1% acceptable as upgrade)
• Power rating: Equal to or greater than 0.1W (0.125W, 0.26W acceptable)
• Operating temperature range: Equal to or exceeding -55°C ~ 155°C
• Certifications and features: May include additional qualifications (AEC-Q200, Military, Anti-Sulfur)
• Product status: Active preferred over obsolete

Substitution Categories:

Direct Substitute: RN73R2ATTD1002F25 maintains identical electrical specifications with increased power rating (0.125W vs 0.1W) and adds automotive AEC-Q200 qualification while preserving all core parameters.

Upgrade Substitute: TNPW080510K0BETA provides tighter tolerance (±0.1% vs ±1%) and military-grade construction with equivalent power rating (0.125W), though operating temperature maximum is reduced to 125°C.

MFR Recommended Substitute: TNPW080510K0BEEA offers the highest performance envelope with ±0.1% tolerance, 0.26W power rating, extended operating temperature to 175°C, automotive AEC-Q200 qualification, and anti-sulfur features, with full RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliant Applications: Select either RN73R2ATTD1002F25 or TNPW080510K0BEEA. Both maintain full ROHS3 compliance required for regulated markets and consumer electronics. RN73R2ATTD1002F25 provides direct electrical equivalence with minimal design impact. TNPW080510K0BEEA offers enhanced performance specifications and extended temperature range for demanding applications.

For Automotive Applications: RN73R2ATTD1002F25 and TNPW080510K0BEEA both carry AEC-Q200 automotive qualification. TNPW080510K0BEEA additionally includes anti-sulfur protection and higher power dissipation capability (0.26W), suitable for under-hood and high-reliability automotive circuits.

For Military or High-Reliability Applications: TNPW080510K0BETA provides military-grade construction with ±0.1% tolerance precision. Note that this part is RoHS non-compliant and has a reduced maximum operating temperature of 125°C compared to the original specification of 155°C.

For General-Purpose Replacement with Maximum Availability: TNPW080510K0BEEA is the manufacturer-recommended substitute with the highest inventory level (60,400 pcs) and broadest performance envelope, including extended temperature range to 175°C and superior tolerance specification.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD1002F25 be used as a direct drop-in replacement for RN732ATTD1002F25?

A: Yes. RN73R2ATTD1002F25 maintains identical resistance value (10 kOhms), tolerance (±1%), package format (0805), composition (thin film), temperature coefficient (±25ppm/°C), and moisture sensitivity level (MSL 1). The increased power rating (0.125W vs 0.1W) and automotive AEC-Q200 qualification represent functional improvements with no compatibility issues.

Q: What is the primary difference between TNPW080510K0BETA and TNPW080510K0BEEA?

A: TNPW080510K0BETA is military-grade with ±0.1% tolerance and 0.125W power rating, with maximum operating temperature of 125°C and RoHS non-compliance. TNPW080510K0BEEA is automotive-qualified (AEC-Q200) with ±0.1% tolerance, 0.26W power rating, extended operating temperature to 175°C, anti-sulfur protection, and full ROHS3 compliance. TNPW080510K0BEEA is the manufacturer-recommended option for most applications.

Q: Are all substitute parts available in the same packaging options as the original?

A: RN732ATTD1002F25 was supplied in standard packaging. RN73R2ATTD1002F25 is available in Tape & Reel (TR). TNPW080510K0BETA is available in Tape & Reel (TR). TNPW080510K0BEEA is available in Cut Tape (CT) & Digi-Reel®. Packaging format should be confirmed with procurement requirements.

Q: Can TNPW080510K0BEEA be used in applications requiring operation above 155°C?

A: Yes. TNPW080510K0BEEA extends the maximum operating temperature to 175°C, providing 20°C additional margin beyond the original RN732ATTD1002F25 specification of 155°C.

Q: Which substitute part is recommended for new designs?

A: TNPW080510K0BEEA is the manufacturer-recommended substitute for new designs. It provides the broadest performance envelope with ±0.1% tolerance, 0.26W power rating, extended temperature range (-55°C ~ 175°C), automotive AEC-Q200 qualification, anti-sulfur protection, full ROHS3 compliance, and highest inventory availability.

Q: Is tolerance tightening from ±1% to ±0.1% a concern for circuit compatibility?

A: No. Tighter tolerance (±0.1%) is a functional improvement that enhances circuit performance and stability. All substitute parts with ±0.1% tolerance are fully compatible with designs specified for ±1% tolerance.
