Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN732ATTD3012A05 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 30.1 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±5ppm/°C
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: Equal to or tighter than ±0.05%
• Power Rating: Equal to or greater than 0.1W
• Operating Temperature Range: Must encompass or exceed -55°C ~ 155°C minimum
• Features: May include additional protective features (moisture resistant, anti-corrosive, flame proof, anti-sulfur)
• RoHS Status: ROHS3 Compliant preferred; non-compliant parts noted
• Product Status: Active parts preferred over obsolete

Substitute parts are grouped into two categories: direct equivalents (matching power rating and tolerance) and upgrades (enhanced power rating and/or improved tolerance).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance & Power Rating):

RN73R2ATTD3012A05 is the primary direct substitute. This part maintains the ±0.05% tolerance and 0805 package specification of the original RN732ATTD3012A05. The power rating increase from 0.1W to 0.125W provides additional thermal margin without affecting circuit performance. The part is manufactured by the same supplier (KOA Speer Electronics), carries active product status, and maintains ROHS3 compliance. Automotive AEC-Q200 qualification provides enhanced reliability documentation.

Upgraded Alternatives (Enhanced Performance):

PLTT0805Z3012AGT5 and PLTT0805Z3012QGT5 offer increased power dissipation capability (0.25W) and extended operating temperature range (-55°C ~ 215°C). PLTT0805Z3012AGT5 maintains ±0.05% tolerance matching the original specification. PLTT0805Z3012QGT5 provides tighter ±0.02% tolerance. Both are ROHS3 compliant and active products from Vishay Dale Thin Film.

TNPU080530K1AZEN00 provides ±0.05% tolerance matching with 0.125W power rating and AEC-Q200 automotive qualification. Operating temperature range is -55°C ~ 125°C, which covers the original specification minimum but does not extend to 155°C maximum.

PLT0805Z3012LBTS offers the tightest tolerance (±0.01%) and highest power rating (0.25W) with extended temperature range (-55°C ~ 125°C). This part is RoHS non-compliant and should be selected only when RoHS compliance is not a design requirement.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD3012A05 directly replace RN732ATTD3012A05 in my circuit?

A: Yes. RN73R2ATTD3012A05 is a direct substitute. Both parts share identical resistance (30.1 kOhms), tolerance (±0.05%), temperature coefficient (±5ppm/°C), package (0805), and operating temperature range (-55°C ~ 155°C). The increased power rating (0.125W vs. 0.1W) provides additional thermal headroom and does not affect circuit operation.

Q: What is the difference between the Vishay Dale upgrade options?

A: PLTT0805Z3012AGT5, PLTT0805Z3012QGT5, and PLT0805Z3012LBTS all provide 0.25W power rating and 0805 package compatibility. PLTT0805Z3012QGT5 offers the tightest tolerance at ±0.02%. PLT0805Z3012LBTS provides ±0.01% tolerance but is RoHS non-compliant. PLTT0805Z3012AGT5 maintains ±0.05% tolerance with extended temperature range to 215°C and ROHS3 compliance.

Q: Does operating temperature range affect substitution compatibility?

A: Operating temperature range must encompass the original specification minimum of -55°C to 155°C. PLTT0805Z3012AGT5 and PLTT0805Z3012QGT5 exceed this requirement (-55°C ~ 215°C). TNPU080530K1AZEN00 and PLT0805Z3012LBTS reach only 125°C maximum, which does not cover the original 155°C specification and should be evaluated against actual circuit requirements.

Q: Is RoHS compliance a critical factor in selecting a substitute?

A: RoHS compliance status depends on application requirements and regulatory jurisdiction. RN73R2ATTD3012A05, PLTT0805Z3012AGT5, PLTT0805Z3012QGT5, and TNPU080530K1AZEN00 are ROHS3 compliant. PLT0805Z3012LBTS is RoHS non-compliant. Verify compliance requirements before final part selection.

Q: Can I use a tighter tolerance part as a substitute?

A: Yes. Parts with tolerance equal to or tighter than ±0.05% are acceptable substitutes. PLTT0805Z3012QGT5 (±0.02%) and PLT0805Z3012LBTS (±0.01%) provide improved tolerance performance without degrading circuit specifications.

Q: What packaging format is used for all substitute parts?

A: All substitute parts use 0805 (2012 Metric) package format, identical to the original RN732ATTD3012A05. Physical dimensions and PCB footprint compatibility are maintained across all listed alternatives.
