Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 6-1879062-8 are classified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters for Substitution:

• Capacitance: 0.1 µF (exact match required)
• Voltage Rating: 35 V minimum (equal or higher acceptable)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Type: Molded Tantalum (exact match required)

Secondary Parameters (Allowable Variation):

• Tolerance: ±20% or tighter (±10% acceptable as upgrade)
• ESR: 10 Ohm baseline; variations up to 24 Ohm acceptable within molded tantalum specifications
• Voltage Rating: 50 V acceptable as performance upgrade over 35 V requirement

Substitute parts are grouped into two categories:

Direct Equivalents (Same Electrical Specifications): Parts matching 0.1 µF, 35 V, ±20% tolerance, and 1206 package with active product status.

Performance Upgrades: Parts with enhanced voltage ratings (50 V) or improved tolerance (±10%) while maintaining all other critical parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: T494A104K050AT (KEMET)

The KEMET T494A104K050AT is the preferred upgrade substitute. This part maintains all critical mechanical and electrical parameters while providing enhanced performance specifications. The 50 V voltage rating exceeds the original 35 V requirement, providing additional design margin. The ±10% tolerance is superior to the original ±20% specification. The part carries active product status with ROHS3 compliance and identical MSL rating. Lifetime specification of 2000 Hrs @ 125°C is documented. Packaging is Tape & Reel (TR) format with 8738 units in stock.

Secondary Recommendations: Direct Equivalents

The following parts provide direct electrical equivalence to the original 6-1879062-8 specification:

• T491A104M035AT (KEMET): Active status, ROHS3 compliant, 2000 Hrs @ 125°C lifetime rating, Tape & Reel packaging, 2018 units in stock.
• 293D104X0035A2TE3 (Vishay Sprague): Active status, ROHS3 compliant, Cut Tape & Digi-Reel packaging, 3840 units in stock.
• TAJA104M035YNJ (KYOCERA AVX): Active status, ROHS3 compliant, Tape & Reel packaging, 984 units in stock.
• TAJS104M035RNJ (KYOCERA AVX): Active status, ROHS3 compliant, Tape & Reel packaging, 700 units in stock. Note: Reduced height of 0.047" (1.20mm) versus standard 0.071" (1.80mm).
• TAJA104M035R (KYOCERA AVX): Active status, ROHS3 compliant, 981 units in stock.

All substitute parts maintain surface mount compatibility, identical operating temperature range, and MSL 1 rating. Selection among direct equivalents depends on packaging format requirements, inventory availability, and ESR tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can the T494A104K050AT (50 V rating) be used in place of the original 6-1879062-8 (35 V rating)?

A: Yes. The 50 V rating of the T494A104K050AT exceeds the 35 V requirement of the original part. Higher voltage ratings provide additional design margin and are electrically compatible with circuits designed for 35 V operation. All other critical parameters (capacitance, package, temperature range, mounting type) are identical.

Q: What is the difference between the direct equivalent parts and the T494A104K050AT upgrade?

A: Direct equivalent parts (T491A104M035AT, 293D104X0035A2TE3, TAJA104M035YNJ, TAJS104M035RNJ, TAJA104M035R) match the original 35 V voltage rating and ±20% tolerance. The T494A104K050AT provides a 50 V rating and ±10% tolerance, both representing performance improvements. Selection depends on whether the design requires exact specification matching or can benefit from enhanced performance parameters.

Q: Are there mechanical compatibility concerns with the TAJS104M035RNJ substitute?

A: The TAJS104M035RNJ has a reduced seated height of 0.047" (1.20mm) compared to the standard 0.071" (1.80mm) of the original part and other substitutes. This difference must be evaluated against PCB layout and clearance requirements. All other mechanical dimensions (length, width, package type) remain identical.

Q: What does ESR variation mean for circuit performance?

A: ESR (Equivalent Series Resistance) affects high-frequency performance and ripple current handling. The original part specifies 10 Ohm ESR. Substitute parts range from 10 Ohm (T494A104K050AT) to 24 Ohm (KYOCERA AVX parts). Higher ESR values are within acceptable molded tantalum specifications but may affect performance in noise-sensitive or high-frequency applications. Circuit-specific requirements determine acceptable ESR ranges.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed carry ROHS3 compliance certification. The original 6-1879062-8 does not specify RoHS status. All parts maintain REACH Unaffected status and EAR99 export classification.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake-out requirements. All parts, including the original and all substitutes, carry this rating, eliminating moisture-related handling constraints.

Q: Which substitute offers the best inventory availability?

A: The T494A104K050AT (KEMET) offers the highest inventory level with 8738 units in stock, followed by the 293D104X0035A2TE3 (Vishay Sprague) with 3840 units. Direct equivalent alternatives range from 700 to 2018 units in stock.

Q: Can packaging format (Tape & Reel vs. Cut Tape) affect part selection?

A: Packaging format affects procurement and assembly processes but not electrical or mechanical compatibility. Tape & Reel (TR) format is standard for high-volume automated assembly. Cut Tape (CT) format is suitable for lower-volume or manual assembly operations. The 293D104X0035A2TE3 offers Cut Tape & Digi-Reel packaging as an alternative to standard Tape & Reel options.
