Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1879062-7 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 1.5 µF
• Tolerance: ±10%
• Voltage Rating: 10 V (minimum)
• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 125°C

Allowable Variation Parameters:

• ESR (Equivalent Series Resistance): Variations within component design specifications are acceptable
• Manufacturer Size Code: Variations permitted if physical dimensions remain within 1206 package constraints
• Height - Seated (Max): Minor variations acceptable within package envelope

Substitute parts are classified into two categories:

Direct Equivalents (10V Rated): Parts matching all mandatory parameters with identical voltage rating. These provide pin-for-pin and functional compatibility.

Upgraded Substitutes (Higher Voltage Rating): Parts with identical capacitance, tolerance, package, and temperature range but rated for 20V operation. These provide enhanced voltage margin and are electrically compatible in 10V applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection (10V Rated Parts):

The following parts provide direct functional equivalence to the TE Connectivity 1-1879062-7:

• 293D155X9010A2TE3 (Vishay Sprague): Active product status with ROHS3 compliance. Identical voltage rating and package specifications. ESR of 8 Ohm represents a minor increase from the original 6 Ohm specification, within acceptable operational parameters for general purpose tantalum capacitor applications.

• TAJA155K010SNJ (KYOCERA AVX): Active product status with ROHS3 compliance. Supplied in Tape & Reel packaging. Identical voltage rating and package specifications. ESR specification not provided; verify against application requirements if ESR is a critical design parameter.

• TAJA155K010R (KYOCERA AVX): Active product status with ROHS3 compliance. Identical voltage rating and package specifications. ESR specification not provided; verify against application requirements if ESR is a critical design parameter.

Upgraded Substitute Selection (20V Rated Part):

• 293D155X9020A2TE3 (Vishay Sprague): Active product status with ROHS3 compliance. Provides enhanced voltage margin with 20V rating in identical package and capacitance specifications. ESR of 6.3 Ohm closely matches the original 6 Ohm specification. Suitable for applications where increased voltage headroom is beneficial.

Special Consideration:

• TAJS155K010RNJ (KYOCERA AVX): Active product status with ROHS3 compliance. Meets all mandatory electrical parameters but features reduced height (0.047" vs. 0.071" maximum seated height) due to Manufacturer Size Code S designation. ESR of 20 Ohm represents a significant increase from the original specification. Selection requires confirmation that reduced height and elevated ESR are compatible with circuit design requirements.

All substitute parts maintain identical operating temperature range (-55°C to 125°C), surface mount configuration, and MSL rating (1 - Unlimited) as the original component.

Frequently Asked Questions (FAQ)

Q: Can the 293D155X9020A2TE3 (20V rated) be used as a direct replacement for the 1-1879062-7 (10V rated)?

A: Yes. The 293D155X9020A2TE3 is electrically compatible in applications designed for 10V operation. The higher voltage rating provides additional safety margin and does not degrade performance in lower voltage circuits. All other electrical and mechanical parameters match the original specification.

Q: What is the significance of the ESR (Equivalent Series Resistance) variation between substitute parts?

A: ESR affects capacitor performance in high-frequency applications and ripple current handling. The original part specifies 6 Ohm ESR. Substitute parts with similar ESR values (293D155X9020A2TE3 at 6.3 Ohm, 293D155X9010A2TE3 at 8 Ohm) are suitable for general purpose applications. The TAJS155K010RNJ with 20 Ohm ESR represents a significant increase and requires application-specific evaluation.

Q: Are all substitute parts RoHS compliant?

A: Yes. All active substitute parts listed are ROHS3 compliant. The original TE Connectivity part does not specify RoHS status.

Q: What is the difference between TAJA155K010SNJ and TAJA155K010R?

A: Both parts are electrically identical 1.5 µF, 10V, 1206 package tantalum capacitors from KYOCERA AVX. The primary difference is packaging: TAJA155K010SNJ is supplied in Tape & Reel format, while TAJA155K010R packaging is not specified. Selection depends on procurement and assembly requirements.

Q: Why does TAJS155K010RNJ have a different height specification?

A: The TAJS155K010RNJ uses Manufacturer Size Code S, resulting in a maximum seated height of 0.047" (1.20mm) compared to 0.071" (1.80mm) for Size Code A parts. This reduced height may be advantageous in space-constrained designs but requires verification that the component fits within the original PCB layout and clearance specifications.

Q: Are all substitute parts available in the same packaging options?

A: No. The 293D155X9020A2TE3 is specified as Tape & Reel packaging. The 293D155X9010A2TE3 packaging is not specified. KYOCERA AVX parts vary: TAJA155K010SNJ is Tape & Reel, while TAJA155K010R and TAJS155K010RNJ packaging is not specified. Confirm packaging availability with component suppliers for procurement planning.

Q: Can ESR specification gaps in KYOCERA AVX parts affect substitution decisions?

A: ESR is not specified for TAJA155K010SNJ and TAJA155K010R. If ESR is a critical design parameter for your application, contact the manufacturer for specification data or select parts with documented ESR values (293D155X9010A2TE3 or 293D155X9020A2TE3).

Q: Do all substitute parts maintain the same operating temperature range?

A: Yes. All substitute parts operate across the identical temperature range of -55°C to 125°C as the original TE Connectivity 1-1879062-7.

Q: What is the inventory status of substitute parts?

A: Current inventory levels are: 293D155X9010A2TE3 (981 pcs), 293D155X9020A2TE3 (2895 pcs), TAJA155K010SNJ (862 pcs), TAJA155K010R (801 pcs), and TAJS155K010RNJ (787 pcs). Inventory levels are subject to change; confirm availability with suppliers for production requirements.
