Substitute Part Grouping Explanation

The LTR10EZPJ104 can be substituted with the LTR10EZPF1003 based on the following criteria:

Matching Parameters (Required for Substitution):

• Resistance value: 100 kOhms (identical)
• Power rating: 0.25W, 1/4W (identical)
• Package: Wide 0805 (2012 Metric) (identical)
• Composition: Thick Film (identical)
• Operating temperature range: -55°C to 155°C (identical)
• Automotive qualification: AEC-Q200 (identical)
• Termination count: 2 (identical)
• Physical dimensions: 0.047" L x 0.079" W, 0.026" max height (identical)
• RoHS compliance: ROHS3 Compliant (identical)
• Moisture sensitivity: MSL 1 (Unlimited) (identical)

Differentiating Parameter:

• Tolerance: LTR10EZPJ104 has ±5% tolerance; LTR10EZPF1003 has ±1% tolerance (tighter specification)

The substitute part offers improved tolerance performance while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the LTR10EZPJ104 and LTR10EZPF1003 are active production components from Rohm Semiconductor with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts depends on circuit tolerance requirements:

• Use LTR10EZPJ104 when ±5% tolerance meets circuit specifications and cost optimization is prioritized.
• Use LTR10EZPF1003 when tighter ±1% tolerance is required for precision applications or when improved temperature coefficient stability (±100ppm/°C versus ±200ppm/°C) is necessary.

Both parts are mechanically and thermally identical, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can LTR10EZPF1003 be used as a direct replacement for LTR10EZPJ104?

A: Yes. Both parts share identical package dimensions, power rating, operating temperature range, and AEC-Q200 automotive qualification. The LTR10EZPF1003 provides tighter tolerance (±1% versus ±5%) and improved temperature coefficient, making it a compatible upgrade.

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

A: The main difference is tolerance specification. LTR10EZPJ104 is rated at ±5%, while LTR10EZPF1003 is rated at ±1%. Additionally, LTR10EZPF1003 has a lower temperature coefficient (±100ppm/°C versus ±200ppm/°C).

Q: Are both parts suitable for automotive applications?

A: Yes. Both the LTR10EZPJ104 and LTR10EZPF1003 carry AEC-Q200 qualification and are designed for automotive use with pulse withstanding capability.

Q: Will substitution require PCB layout changes?

A: No. Both resistors use the identical Wide 0805 (2012 Metric) package with matching physical dimensions (0.047" L x 0.079" W, 0.026" max height), ensuring direct footprint compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both LTR10EZPJ104 and LTR10EZPF1003 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
