Substitute Part Grouping Explanation

Substitution of the T496C105K050AS is determined by strict equivalence across the following parameters:

Primary Substitution Criteria:

• Capacitance: 1 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 50 V (exact match required)
• Package / Case: 2312 (6032 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Secondary Compatibility Parameters:

• Physical dimensions must match within specified tolerances
• Fail Safe with Built-in Fuse feature must be present
• Moisture Sensitivity Level 1 classification must be maintained

The substitute part T496C105K050ATE5K5 meets all primary and secondary criteria. The primary distinction between the main part and its substitute is the product status (obsolete versus active) and packaging format (bulk versus tape & reel), along with specified ESR and lifetime ratings for the active substitute.

Parameter Comparison

Engineering Selection Recommendations

The T496C105K050ATE5K5 is the direct active substitute for the obsolete T496C105K050AS. Selection of this substitute is based on the following engineering factors:

Product Status: The T496C105K050ATE5K5 carries an active product status, ensuring continued availability and manufacturer support. The original part is classified as obsolete, making the substitute the appropriate choice for new designs and ongoing production requirements.

Regulatory Compliance: The substitute part is ROHS3 compliant, whereas the main part is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic components in many markets.

Electrical Equivalence: Both parts maintain identical electrical specifications across capacitance (1 µF), tolerance (±10%), and voltage rating (50 V). The substitute provides specified ESR (5.5 Ohm) and lifetime rating (2000 Hrs @ 85°C), offering additional performance documentation.

Physical Compatibility: Mechanical dimensions, package type, and mounting configuration are identical between the main part and substitute, ensuring direct board-level compatibility without design modification.

Packaging Consideration: The substitute is supplied in Tape & Reel format, which is standard for production environments. If bulk packaging is required, alternative sourcing or reeling services may be necessary.

Frequently Asked Questions (FAQ)

Q: Can T496C105K050ATE5K5 be used as a direct replacement for T496C105K050AS on existing circuit boards?

A: Yes. Both parts share identical electrical specifications (1 µF, ±10%, 50 V), physical dimensions (2312 package, 6.00mm x 3.20mm x 2.80mm max height), and mounting type (surface mount). No circuit design changes are required.

Q: What is the primary reason for substitution?

A: The T496C105K050AS is classified as obsolete. The T496C105K050ATE5K5 is the active equivalent from the same manufacturer and series, ensuring continued supply chain access.

Q: Are there differences in electrical performance between these parts?

A: Both parts meet the same electrical requirements. The substitute provides specified ESR (5.5 Ohm) and lifetime rating (2000 Hrs @ 85°C), whereas these parameters are not specified for the obsolete part. Operating temperature range (-55°C ~ 125°C) is identical.

Q: What is the difference in packaging between these parts?

A: The main part is supplied in bulk packaging. The substitute is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The T496C105K050ATE5K5 is ROHS3 compliant. The original part is RoHS non-compliant, making the substitute the appropriate choice for applications subject to RoHS regulations.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 2312 (6032 Metric) package with dimensions of 0.236" L x 0.126" W (6.00mm x 3.20mm) and maximum seated height of 0.110" (2.80mm). No PCB layout modifications are necessary.

Q: What is the moisture sensitivity level for the substitute?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
