Primary Substitution Criteria:

Capacitance: 100 µF (exact match required)
Voltage Rating: 16 V (exact match required)
Tolerance: ±20% (exact match required)
Package / Case: 2917 (7343 Metric) (exact match required)
Mounting Type: Surface Mount (exact match required)
Operating Temperature Range: -55°C to 125°C (exact match required)
ESR: 900 mOhm (exact match required)

Engineering Selection Recommendations

Direct Substitutes (Recommended Primary Selection):

The KYOCERA AVX TAJ series parts TAJY107M016RNJ, TAJY107M016SNJ, and TAJY107M016Y are direct functional equivalents to the 1-1676904-9. All three maintain identical electrical specifications (100 µF, ±20%, 16 V, 900 mOhm ESR) and package dimensions. These parts are manufactured by an active supplier with ROHS3 compliance certification. The primary advantage of these direct substitutes is their reduced seated height (0.079" versus 0.118"), which may provide improved PCB layout flexibility. TAJY107M016RNJ is available in Tape & Reel packaging, suitable for automated assembly processes.

Upgrade Substitutes (Enhanced Tolerance):

The KYOCERA AVX TAJ series parts TAJY107K016A, TAJY107K016RNJ, and TAJY107K016Y provide improved capacitance tolerance of ±10% while maintaining all other electrical and mechanical specifications of the original part. These upgrades are suitable for applications requiring tighter capacitance accuracy. TAJY107K016RNJ offers the highest inventory availability (4,818 pieces) and Tape & Reel packaging for production environments.

Similar Substitutes (Alternative Consideration):

The Vishay Sprague 293D series (293D107X0016D2TE3 and 293D107X0016E2TE3) maintain electrical equivalence but feature reduced ESR (600 mOhm versus 900 mOhm). These parts are suitable for applications where lower ESR provides performance benefits. The Vishay Sprague 592D series (592D107X0016D2T15H and 592D107X0016D2T20H) are conformal coated variants with significantly lower ESR (150 mOhm) and different moisture sensitivity classification (MSL 2A). Conformal coated variants are specified for harsh environmental conditions and require design verification for compatibility with existing assembly processes.

Frequently Asked Questions (FAQ)

Q: Can TAJY107M016RNJ directly replace 1-1676904-9 without design changes?

A: Yes. TAJY107M016RNJ is a direct functional equivalent with identical capacitance (100 µF), tolerance (±20%), voltage rating (16 V), ESR (900 mOhm), package (2917), and operating temperature range (-55°C to 125°C). The reduced seated height (0.079" versus 0.118") is a physical improvement that does not affect electrical performance or PCB compatibility.

Q: What is the difference between the TAJY107M016 and TAJY107K016 series?

A: The primary difference is capacitance tolerance. TAJY107M016 parts specify ±20% tolerance, while TAJY107K016 parts specify ±10% tolerance. All other electrical and mechanical parameters remain identical. The K-series upgrade is appropriate for applications requiring tighter capacitance accuracy.

Q: Why do the Vishay Sprague 293D parts have lower ESR (600 mOhm)?

A: ESR is a manufacturing characteristic that varies by design and process. The 293D series achieves lower ESR through different internal construction while maintaining the same capacitance, voltage, tolerance, and package specifications. Lower ESR reduces heat generation and improves high-frequency performance in certain applications.

Q: Are the conformal coated 592D parts compatible with standard assembly processes?

A: The 592D series conformal coated parts are compatible with standard surface mount assembly equipment and PCB layouts. However, the conformal coating affects moisture sensitivity classification (MSL 2A versus MSL 1), which may impact storage and handling requirements. Design verification is recommended for applications with specific environmental or reliability specifications.

Q: What does MSL 1 (Unlimited) mean compared to MSL 2A (4 Weeks)?

A: MSL 1 indicates unlimited shelf life without moisture absorption concerns. MSL 2A indicates a 4-week floor life limit after package opening, requiring controlled storage conditions. The original 1-1676904-9 and all direct/upgrade substitutes carry MSL 1 classification. The conformal coated 592D variants carry MSL 2A classification, requiring more stringent moisture control during storage and assembly.

Q: Can I use TAJY107K016RNJ as a drop-in replacement for cost or availability reasons?

A: Yes. TAJY107K016RNJ is functionally superior to 1-1676904-9 due to improved tolerance (±10% versus ±20%) while maintaining all other specifications. This upgrade substitution is appropriate for any application originally designed for the 1-1676904-9 and provides enhanced capacitance accuracy at no performance penalty.

Q: What packaging options are available for production environments?

A: TAJY107M016RNJ and TAJY107K016RNJ are available in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly. TAJY107M016SNJ, TAJY107M016Y, TAJY107K016A, and TAJY107K016Y are available in standard packaging. The Vishay Sprague 293D and 592D series are available in Tape & Reel packaging.

Q: Are all substitute parts ROHS3 compliant?

A: All KYOCERA AVX TAJ series substitutes (TAJY107M016RNJ, TAJY107M016SNJ, TAJY107M016Y, TAJY107K016A, TAJY107K016RNJ, TAJY107K016Y) are ROHS3 compliant. All Vishay Sprague 293D and 592D series parts are ROHS3 compliant. The original 1-1676904-9 does not specify RoHS status.
