Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WK73S2JTTE95L3F is determined by the following critical parameters:

• Resistance value: 95.3 MOhms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive AEC-Q200 qualification
• Moisture-resistant construction
• RoHS3 compliance

The WK73S2HTTE95L3F qualifies as a substitute based on matching all electrical specifications and compliance certifications. The primary difference is the package format: Wide 2010 (5025 Metric) versus Wide 1812 (4532 Metric). This substitution is valid where PCB layout and space constraints permit the alternative package footprint.

Parameter Comparison

Engineering Selection Recommendations

The WK73S2HTTE95L3F is the recommended substitute for the WK73S2JTTE95L3F. The substitute part maintains identical electrical performance, temperature characteristics, and automotive compliance ratings. The WK73S2HTTE95L3F carries Active product status, ensuring long-term availability and supply chain continuity compared to the Not For New Designs status of the original part.

Selection of the substitute requires PCB layout modification to accommodate the Wide 2010 (5025 Metric) package footprint in place of the Wide 1812 (4532 Metric) footprint. Both parts maintain equivalent height and moisture sensitivity specifications, supporting direct functional replacement in automotive applications requiring AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can WK73S2HTTE95L3F be used as a direct replacement for WK73S2JTTE95L3F?

A: Electrical and thermal performance are equivalent. PCB layout modification is required due to different package dimensions. The substitute part is physically larger in length and width but maintains the same maximum seated height.

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

A: The main difference is the package format. WK73S2JTTE95L3F uses Wide 1812 (4532 Metric) packaging, while WK73S2HTTE95L3F uses Wide 2010 (5025 Metric) packaging. All electrical specifications, tolerance, power rating, and compliance certifications are identical.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification and are rated for -55°C to 155°C operating temperature. Both are ROHS3 compliant and moisture resistant.

Q: Why is the original part marked as Not For New Designs?

A: The WK73S2JTTE95L3F is in end-of-life status. The WK73S2HTTE95L3F is the active equivalent and should be used for new designs and ongoing production.

Q: Do these parts have the same moisture sensitivity level?

A: Yes. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.
