Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN732BTTD7592C10 is determined by the following critical parameters:

Resistance value and tolerance must remain identical at 75.9 kOhms ±0.25%. The package format must be 1206 (3216 Metric) to ensure mechanical and electrical compatibility with existing PCB layouts. Composition must be thin film to maintain the specified temperature coefficient of ±10ppm/°C and precision characteristics. Operating temperature range must encompass or equal -55°C to 155°C. Power rating may be equal to or greater than 0.125W, as higher power-rated components remain functionally compatible in applications requiring lower power dissipation. RoHS3 compliance and MSL 1 rating must be maintained for regulatory and manufacturing process compatibility.

The substitute part RN73R2BTTD7592C10 meets all substitution criteria while offering enhanced product status and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2BTTD7592C10 is the direct substitute for the obsolete RN732BTTD7592C10. Both components maintain identical electrical specifications including resistance value, tolerance, temperature coefficient, and operating temperature range. The substitute part offers increased power rating (0.25W versus 0.125W), which provides additional thermal margin without affecting circuit performance in applications designed for the original 0.125W specification.

The RN73R2BTTD7592C10 carries Active product status, ensuring long-term availability and manufacturing support. The component includes AEC-Q200 automotive qualification in addition to the moisture-resistant construction present in the original part. Both parts maintain ROHS3 compliance and MSL 1 rating, supporting equivalent manufacturing and supply chain processes.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2BTTD7592C10 be used as a direct replacement for the RN732BTTD7592C10?

A: Yes. Both components share identical resistance value (75.9 kOhms), tolerance (±0.25%), package format (1206), composition (thin film), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C to 155°C). The substitute part has a higher power rating (0.25W versus 0.125W), which is compatible with applications designed for the original specification.

Q: What is the significance of the power rating difference between these parts?

A: The RN73R2BTTD7592C10 has a 0.25W power rating compared to the 0.125W rating of the RN732BTTD7592C10. In circuit applications, the substitute part can dissipate twice the power without exceeding its thermal limits. This provides additional design margin and does not negatively impact circuits designed for the lower power rating.

Q: Are the physical dimensions identical between the main part and substitute?

A: Yes. Both components are packaged in 1206 (3216 Metric) format with identical dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum seated height of 0.028" (0.70mm). PCB layout and footprint compatibility is maintained.

Q: What does AEC-Q200 qualification mean for the substitute part?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions. The RN73R2BTTD7592C10 meets this qualification, while the original RN732BTTD7592C10 does not carry this designation. This makes the substitute part suitable for both general industrial and automotive applications.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and manufacturing process compatibility is maintained between the original and substitute components.
