Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 6-1879062-1 is determined by strict equivalence across the following critical parameters:

Direct Substitution Criteria (Same Electrical and Mechanical Specifications):

• Capacitance: 0.68 µF
• Tolerance: ±10%
• Voltage Rating: 25 V
• Type: Molded Tantalum
• Package / Case: 1206 (3216 Metric)
• Operating Temperature Range: -55°C to 125°C
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

Upgrade Substitution Criteria (Higher Voltage Rating):

• All parameters identical to direct substitution except Voltage Rating: 35 V
• Upgrades provide enhanced voltage margin while maintaining all other electrical and mechanical characteristics

Similar Substitution Criteria (Minor Parameter Variations):

• Capacitance, tolerance, voltage, package, and temperature range remain identical
• ESR values may vary within acceptable operational ranges
• Height or manufacturer size code may differ
• RoHS compliance status may differ from original part

Parts are grouped based on these parameter alignments to enable proper component selection for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Equivalent Electrical and Mechanical Performance):

TPSA684K025R6000 (KYOCERA AVX) is the primary direct replacement for the obsolete TE Connectivity 6-1879062-1. This part maintains identical capacitance (0.68 µF), voltage rating (25 V), ESR (6 Ohm), package dimensions (1206), and operating temperature range (-55°C to 125°C). The part is active in production and carries ROHS3 compliance certification, addressing regulatory requirements for new designs.

Upgraded Voltage Rating Option:

TPSA684K035R6000 and TPSA684K035Y6000 (KYOCERA AVX) provide 35 V rated alternatives while maintaining all other electrical and mechanical specifications of the original part. These upgrades are suitable for applications requiring enhanced voltage margin. Both parts are active and ROHS3 compliant.

Alternative Manufacturers (Same Electrical Specifications):

293D684X9025A2TE3 (Vishay Sprague TANTAMOUNT™ 293D series) provides equivalent capacitance, tolerance, voltage, and package specifications. ESR is 8.4 Ohm compared to the original 6 Ohm specification. This part is active and ROHS3 compliant.

T491A684K025AT (KEMET T491 series) offers equivalent electrical specifications with 10 Ohm ESR. This part is active and ROHS3 compliant, available in Cut Tape and Digi-Reel® packaging.

TAJA684K025RNJ (KYOCERA AVX TAJ series) provides equivalent specifications with 10 Ohm ESR. This part is active and ROHS3 compliant.

Height-Constrained Applications:

TAJS684K025RNJ (KYOCERA AVX TAJ series) is suitable for applications with height restrictions, featuring a maximum seated height of 0.047" (1.20mm) compared to the standard 0.071" (1.80mm). All electrical specifications remain equivalent to the original part. This part is active and ROHS3 compliant.

Compliance Considerations:

For new designs requiring RoHS3 compliance, TPSA684K025R6000, TPSA684K035R6000, TPSA684K035Y6000, 293D684X9025A2TE3, T491A684K025AT, TAJA684K025RNJ, and TAJS684K025RNJ are all suitable. T491A684K025AH is RoHS non-compliant and should be avoided in applications requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can TPSA684K035R6000 or TPSA684K035Y6000 be used as direct replacements for the 6-1879062-1?

A: Yes. These parts are functionally compatible as upgrades. They maintain identical capacitance (0.68 µF), tolerance (±10%), package (1206), ESR (6 Ohm), and operating temperature range (-55°C to 125°C). The 35 V rating provides higher voltage margin than the original 25 V specification. Circuit design must accommodate the higher voltage rating.

Q: What is the difference between TAJA684K025RNJ and TAJS684K025RNJ?

A: Both parts are KYOCERA AVX TAJ series with identical electrical specifications (0.68 µF, ±10%, 25 V, 10 Ohm ESR). The primary difference is physical height: TAJA684K025RNJ has a maximum seated height of 0.071" (1.80mm), while TAJS684K025RNJ has a maximum seated height of 0.047" (1.20mm). TAJS684K025RNJ is suitable for space-constrained applications.

Q: Why do some substitute parts have different ESR values?

A: ESR variation is a characteristic of different manufacturer designs and process technologies. The original part specifies 6 Ohm ESR. Substitute parts with 8.4 Ohm (293D684X9025A2TE3) or 10 Ohm (T491A684K025AH, T491A684K025AT, TAJA684K025RNJ, TAJS684K025RNJ) ESR values remain functionally compatible for general-purpose applications. Circuit performance characteristics such as ripple current handling and transient response may be affected by ESR differences.

Q: Is the original TE Connectivity 6-1879062-1 still available?

A: The part is classified as obsolete. While 989 pieces are listed as in stock, new production is not available. TPSA684K025R6000 is the recommended active replacement from KYOCERA AVX.

Q: Which substitute part offers the best compliance profile?

A: TPSA684K025R6000, TPSA684K035R6000, TPSA684K035Y6000, 293D684X9025A2TE3, T491A684K025AT, TAJA684K025RNJ, and TAJS684K025RNJ are all ROHS3 compliant and REACH unaffected. All parts carry EAR99 ECCN classification and 8532.21.0050 HTSUS code. T491A684K025AH is RoHS non-compliant and should not be used in regulated applications.

Q: Can substitute parts with higher ESR values affect circuit performance?

A: ESR affects ripple current handling, transient response, and thermal characteristics. Parts with 10 Ohm ESR (KEMET T491 series, KYOCERA AVX TAJ series) have higher ESR than the original 6 Ohm specification. Circuit analysis is required to determine if the higher ESR is acceptable for specific application requirements.

Q: What packaging options are available for substitute parts?

A: TPSA684K025R6000, TPSA684K035R6000, TPSA684K035Y6000, 293D684X9025A2TE3, TAJA684K025RNJ, and TAJS684K025RNJ are supplied in Tape & Reel (TR) packaging. T491A684K025AT is available in Cut Tape (CT) and Digi-Reel® packaging. T491A684K025AH is supplied in Tape & Reel (TR) packaging.

Q: Are all substitute parts rated for the same operating temperature range?

A: Yes. All substitute parts operate across -55°C to 125°C, matching the original part specification. KEMET T491 series parts specify 2000 hours lifetime at 125°C.
