TCJD337M004R0040 Equivalent & Substitute Parts

Part Overview

The TCJD337M004R0040 is a 330 µF molded tantalum polymer capacitor rated at 4 V, manufactured by KYOCERA AVX in the 2917 (7343 Metric) package. This component is designed for general-purpose applications requiring low equivalent series resistance (ESR) and stable performance across extended temperature ranges. The part is currently active in production with full RoHS3 compliance and REACH unaffected status. Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across the same package footprint and performance envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TCJD337M004R0040 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 4 V (exact match required)
• ESR specification: 40 mOhm @ 100kHz (exact match required)
• Package footprint: 2917 (7343 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Lifetime specification: 2000 Hours @ 105°C (exact match required)
• Type: Molded Tantalum Polymer (exact match required)
• Tolerance: ±20% (exact match required)
• MSL rating: 3 (exact match required)

The identified substitute parts maintain all electrical and mechanical specifications. Variations in physical height (seated dimension) do not affect substitution eligibility when the package footprint and mounting surface remain identical.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TCJD337M004R0040, TCJY337M004R0040, and T520V337M004ATE040—are active production components with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and supply chain requirements, as all electrical and mechanical specifications are equivalent. The TCJY337M004R0040 and T520V337M004ATE040 represent valid direct substitutes for the TCJD337M004R0040 in any application where the specified parameters are required.

Frequently Asked Questions (FAQ)

Q: Can TCJY337M004R0040 replace TCJD337M004R0040 in production?

A: Yes. Both parts are KYOCERA AVX molded tantalum polymer capacitors with identical electrical specifications (330 µF, 4 V, 40 mOhm ESR), the same 2917 package footprint, and equivalent performance ratings. The difference in manufacturer size code (D vs. Y) reflects internal manufacturing designation and does not affect functional compatibility.

Q: Is the T520V337M004ATE040 from KEMET a suitable replacement?

A: Yes. The KEMET T520V337M004ATE040 maintains all critical electrical and mechanical parameters: 330 µF capacitance, 4 V rating, 40 mOhm ESR, 2917 package footprint, and identical operating temperature and lifetime specifications. Cross-manufacturer substitution is valid when all specified parameters match.

Q: Does the difference in seated height affect substitution?

A: No. The TCJD337M004R0040 has a maximum seated height of 0.122" (3.10 mm), while TCJY337M004R0040 and T520V337M004ATE040 are 0.079" (2.00 mm) and 0.075" (1.90 mm) respectively. Since all parts share the identical 2917 (7343 Metric) package footprint and mounting surface, height variation does not impact PCB layout or electrical performance.

Q: Are all three parts RoHS3 compliant?

A: Yes. TCJD337M004R0040, TCJY337M004R0040, and T520V337M004ATE040 are all RoHS3 compliant with REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the MSL rating and why does it matter?

A: All three parts carry MSL 3 (168 Hours) rating. This indicates the maximum time the component can be exposed to moisture at specified temperature and humidity conditions before soldering. Proper storage and handling procedures must be followed to maintain component integrity prior to assembly.
