EPC635-CSP44-002 Equivalent & Substitute Parts

Part Overview

The EPC635-CSP44-002 is a CCD image sensor manufactured by ESPROS Photonics AG, designed for time-of-flight (TOF) imaging applications. It features a 160H x 60V pixel array with 20µm x 20µm pixel dimensions, operating at 512 frames per second. The device is packaged in a 44-CSP (6.26x4.18mm) form factor and operates across a supply voltage range of 2.25V to 3.63V.

This part is currently classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this sensor.

Substitute Part Grouping Explanation

The EPC635-CSP44-003 qualifies as a direct substitute for the EPC635-CSP44-002 based on the following critical parameters:

Matching Parameters:

• Identical manufacturer (ESPROS Photonics AG)
• Identical sensor type (CCD)
• Identical active pixel array (160H x 60V)
• Identical pixel size (20µm x 20µm)
• Identical frame rate (512 fps)
• Identical package type (44-CSP, 44-XFBGA, CSPBGA)
• Identical package dimensions (6.26x4.18mm)
• Identical moisture sensitivity level (MSL 1)
• Identical RoHS and REACH compliance status

Differing Parameters:

• Supply voltage range: EPC635-CSP44-002 operates at 2.25V–3.63V; EPC635-CSP44-003 operates at 1.71V–1.98V
• Operating temperature maximum: EPC635-CSP44-002 rated to 85°C; EPC635-CSP44-003 rated to 105°C
• Product status: EPC635-CSP44-002 is obsolete; EPC635-CSP44-003 is active
• Packaging format: EPC635-CSP44-002 is bulk; EPC635-CSP44-003 is Tape & Reel (TR)

The substitution is valid when the application's voltage and temperature requirements align with the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

The EPC635-CSP44-003 is the manufacturer-recommended substitute for the obsolete EPC635-CSP44-002. Both parts maintain identical optical and imaging specifications, ensuring functional compatibility at the sensor level.

Selection of the EPC635-CSP44-003 is appropriate when:

• The application's power supply operates within the 1.71V–1.98V range
• The operating environment does not exceed 105°C
• Active product status and ongoing manufacturer support are required
• Tape & Reel packaging is acceptable for assembly processes

The EPC635-CSP44-002 should be retained only if the application specifically requires the 2.25V–3.63V supply voltage range or operates exclusively below 85°C, and if existing inventory is available.

Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring equivalent reliability and environmental performance.

Frequently Asked Questions (FAQ)

Q: Can the EPC635-CSP44-003 directly replace the EPC635-CSP44-002 in existing designs?

A: Direct replacement is possible if the application's power supply voltage falls within 1.71V–1.98V and the maximum operating temperature does not exceed 105°C. The identical pixel array, frame rate, and package dimensions ensure optical and mechanical compatibility. If the original design requires 2.25V–3.63V supply voltage, the EPC635-CSP44-003 is not suitable without power supply redesign.

Q: What are the key differences between these two parts?

A: The primary differences are supply voltage range (EPC635-CSP44-002: 2.25V–3.63V; EPC635-CSP44-003: 1.71V–1.98V), maximum operating temperature (EPC635-CSP44-002: 85°C; EPC635-CSP44-003: 105°C), product status (obsolete vs. active), and packaging format (bulk vs. Tape & Reel).

Q: Are the optical specifications identical between these parts?

A: Yes. Both parts feature identical CCD sensor architecture with 160H x 60V pixel arrays, 20µm x 20µm pixel dimensions, and 512 frames per second performance. Optical performance and image quality are equivalent.

Q: Is the 44-CSP package identical for both parts?

A: Yes. Both parts use the 44-CSP (6.26x4.18mm) package with 44-XFBGA and CSPBGA designations. PCB footprints and assembly processes are compatible.

Q: Why is the EPC635-CSP44-002 classified as obsolete?

A: The EPC635-CSP44-002 has been superseded by the EPC635-CSP44-003. The manufacturer recommends transitioning to the active part for new designs and ongoing production support.

Q: Are compliance certifications equivalent?

A: Yes. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 1). Environmental and regulatory compliance is equivalent.
