Key Parameters

Substitute Part Grouping Explanation

Substitution of the LTR10EZPJ331 is determined by the following critical parameters that must remain constant or improve:

• Resistance Value: Must be 330 Ohms
• Power Rating: Must be 1W or greater
• Package Type: Must be Wide 0805 (2012 Metric), 0508
• Composition: Thick Film
• Operating Temperature Range: Must cover -55°C ~ 155°C minimum
• Automotive Compliance: Must maintain AEC-Q200 qualification
• RoHS Compliance: Must be ROHS3 Compliant

The LTR10EZPF3300 qualifies as a direct substitute by maintaining all critical parameters while offering an upgrade in tolerance specification from ±5% to ±1%, which represents an improvement in precision without compromising any electrical or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the LTR10EZPJ331 and LTR10EZPF3300 are active production parts from Rohm Semiconductor with full AEC-Q200 automotive qualification and ROHS3 compliance. The LTR10EZPF3300 represents an upgrade path when circuit design requires improved tolerance performance, offering ±1% tolerance compared to the ±5% specification of the main part. The temperature coefficient improvement from ±200ppm/°C to ±100ppm/°C in the substitute part provides enhanced stability across the full operating temperature range. Both parts share identical package geometry, power rating, and thermal operating limits, ensuring direct mechanical and electrical compatibility in Wide 0805 footprints.

Frequently Asked Questions (FAQ)

Q: Can LTR10EZPF3300 be used as a direct replacement for LTR10EZPJ331?

A: Yes. The LTR10EZPF3300 maintains all critical electrical and mechanical parameters including resistance value, power rating, package type, and operating temperature range. The improved tolerance specification (±1% versus ±5%) represents an enhancement rather than a deviation.

Q: What is the primary difference between these two parts?

A: The main differences are tolerance specification and temperature coefficient. The LTR10EZPF3300 provides ±1% tolerance and ±100ppm/°C temperature coefficient, while the LTR10EZPJ331 offers ±5% tolerance and ±200ppm/°C temperature coefficient. Both maintain identical 1W power rating and Wide 0805 package dimensions.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the LTR10EZPJ331 and LTR10EZPF3300 carry AEC-Q200 qualification and are designed for automotive use with operating temperature range of -55°C to 155°C.

Q: Will the Wide 0805 package fit the same PCB footprint as standard 0805?

A: The Wide 0805 (2012 Metric) package has different dimensions than standard 0805. Verify that your PCB footprint is designed for Wide 0805 specifications: 0.047" L x 0.079" W (1.20mm x 2.00mm).

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

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited). Regulatory and compliance status is equivalent.
