Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-1879064-7 is determined by strict equivalence across the following critical parameters: capacitance value (68 µF), tolerance (±10%), voltage rating (6.3 V), package type (2312/6032 Metric), mounting method (surface mount), and operating temperature range (-55°C to 125°C). All substitute parts must maintain these specifications to ensure functional compatibility within the original circuit design.

Substitute parts are grouped into three categories:

Direct Substitutes (Same Electrical Specifications): Parts with identical capacitance, voltage rating, tolerance, and ESR of 200 mOhm. These parts are pin-compatible and electrically equivalent.

Upgrade Substitutes (Higher Voltage Rating): Parts with identical capacitance, tolerance, and package, but rated for higher voltage (16 V instead of 6.3 V). These provide enhanced voltage margin while maintaining all other specifications.

Similar Substitutes (Variant ESR): Parts with identical capacitance, voltage rating, tolerance, and package, but with different ESR values. These maintain electrical functionality while offering alternative performance characteristics in terms of impedance.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents: TPSC686K006R0200 (KYOCERA AVX) and TR3C686K6R3C0200 (Vishay Sprague) are direct substitutes with identical electrical specifications and ESR characteristics. Both are active products with ROHS3 compliance, providing immediate replacement capability for the obsolete 1-1879064-7.

Voltage Upgrade Option: TPSC686K016R0200 (KYOCERA AVX) offers the same capacitance, tolerance, and ESR while providing a higher 16 V rating. This part is suitable for applications where increased voltage margin is beneficial and circuit design permits the substitution.

Low ESR Alternatives: T491C686K006AT (KEMET), TAJC686K006RNJ (KYOCERA AVX), TAJC686K006SNJ (KYOCERA AVX), and TAJW686K006RNJ (KYOCERA AVX) provide significantly lower ESR values (1.2 Ohm to 1.5 Ohm) compared to the original 200 mOhm specification. These parts are suitable for applications requiring reduced impedance characteristics.

Moderate ESR Alternative: TPSC686K006R0150 (KYOCERA AVX) provides 150 mOhm ESR, offering a middle ground between the original specification and low-ESR alternatives.

Higher ESR Alternative: 293D686X96R3C2TE3 (Vishay Sprague) features 800 mOhm ESR and is suitable for applications where higher impedance is acceptable.

Compact Height Option: TAJW686K006RNJ (KYOCERA AVX) offers a reduced seated height of 0.059" (1.50 mm) compared to standard 0.110" (2.80 mm) packages, enabling space-constrained designs.

All substitute parts maintain the 2312 (6032 Metric) package footprint, -55°C to 125°C operating temperature range, and MSL 1 moisture sensitivity rating. All active substitutes carry ROHS3 compliance certification.

Frequently Asked Questions (FAQ)

Q: Can TPSC686K006R0200 directly replace the 1-1879064-7 without circuit modification?

A: Yes. TPSC686K006R0200 maintains identical capacitance (68 µF), voltage rating (6.3 V), tolerance (±10%), ESR (200 mOhm), and package dimensions (2312/6032 Metric). The maximum seated height difference of 0.004" (0.10 mm) is within standard PCB assembly tolerances.

Q: What is the difference between the direct substitutes TPSC686K006R0200 and TR3C686K6R3C0200?

A: Both parts are electrically identical with 68 µF, 6.3 V, ±10% tolerance, and 200 mOhm ESR. The primary difference is manufacturer: KYOCERA AVX versus Vishay Sprague. Both are active products with ROHS3 compliance. Selection may depend on supply chain availability or preferred vendor qualification.

Q: When should I use TPSC686K016R0200 instead of the direct equivalent?

A: TPSC686K016R0200 is a voltage upgrade option rated for 16 V instead of 6.3 V. Use this part when circuit design permits higher voltage rating and increased voltage margin is desired. All other electrical parameters remain identical to the original specification.

Q: What is the advantage of low-ESR alternatives like T491C686K006AT or TAJC686K006RNJ?

A: These parts reduce ESR from 200 mOhm to 1.2-1.5 Ohm, lowering impedance characteristics. Low-ESR alternatives are beneficial in applications requiring improved transient response, reduced ripple current effects, or enhanced high-frequency performance. Circuit design must accommodate the different ESR value.

Q: Is TAJW686K006RNJ compatible with standard PCB layouts designed for the 1-1879064-7?

A: TAJW686K006RNJ maintains the same 2312 (6032 Metric) footprint and electrical specifications but features a significantly reduced seated height of 0.059" (1.50 mm) versus the standard 0.110" (2.80 mm). PCB layouts designed for standard height components will accommodate this part, but the reduced height may affect solder joint formation. Verify with assembly process specifications.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed carry ROHS3 compliance certification. The original 1-1879064-7 (obsolete) does not specify RoHS status. All substitutes meet current environmental compliance requirements.

Q: What is the difference between TAJC686K006SNJ and TAJC686K006RNJ?

A: Both parts are electrically identical with 68 µF, 6.3 V, ±10% tolerance, 1.5 Ohm ESR, and 2312 (6032 Metric) package. The difference is in the suffix designation (SNJ versus RNJ), which typically indicates different manufacturing batches or tape reel configurations. Electrical performance is equivalent.

Q: Can I use 293D686X96R3C2TE3 with its higher 800 mOhm ESR?

A: Yes, if circuit design permits higher impedance. The 293D686X96R3C2TE3 maintains all other specifications (68 µF, 6.3 V, ±10%, 2312 package). Higher ESR may affect transient response and ripple current characteristics. Verify circuit performance requirements before substitution.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts, including the original 1-1879064-7, carry MSL 1 rating, eliminating moisture-related compatibility concerns.
