Substitute Part Grouping Explanation

Substitution of the T520V337M004ASE012 is determined by strict equivalence across the following parameters:

Critical Substitution Parameters:

  • Capacitance: 330 µF (exact match required)
  • Voltage Rating: 4 V (exact match required)
  • Tolerance: ±20% (exact match required)
  • ESR @ 100 kHz: 12 mOhm (exact match required)
  • Operating Temperature Range: -55°C to 105°C (exact match required)
  • Lifetime @ 105°C: 2000 Hours (exact match required)
  • Package / Case: 2917 (7343 Metric) (exact match required)
  • Mounting Type: Surface Mount (exact match required)
  • Physical Dimensions: 7.30 mm × 4.30 mm × 1.90 mm max (exact match required)
  • Moisture Sensitivity Level: MSL 3 (exact match required)

All identified substitute parts meet these criteria. The primary distinction between substitutes is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and product status (Active versus Obsolete). The main part T520V337M004ASE012 is obsolete; all substitute parts are active products.

Engineering Selection Recommendations

Primary Recommendation: T520V337M004ATE012

The T520V337M004ATE012 is the direct substitute for the obsolete T520V337M004ASE012. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The Cut Tape & Digi-Reel® packaging format provides flexibility for both manual and automated assembly processes. Current inventory of 2200 units supports immediate procurement requirements.

Secondary Recommendations: T520V337M004ATE0124539, T520V337M004ATE0127333, T520V337M004ATE012E009

These three parts are parametric equivalents with identical electrical and mechanical characteristics. All three are active products with ROHS3 compliance. The distinction is packaging format (Tape & Reel) and internal tracking codes. These parts are suitable for high-volume automated assembly operations. Inventory levels range from 628 to 1069 units.

Compliance Consideration:

The original part T520V337M004ASE012 is RoHS non-compliant. All substitute parts are ROHS3 compliant, meeting current regulatory requirements for new designs and procurement cycles.

Frequently Asked Questions (FAQ)

Q: Can T520V337M004ATE012 be used as a direct replacement for T520V337M004ASE012?

A: Yes. The T520V337M004ATE012 is electrically and mechanically identical to the obsolete T520V337M004ASE012. Both parts share the same capacitance (330 µF), voltage rating (4 V), ESR (12 mOhm @ 100 kHz), operating temperature range (-55°C to 105°C), package format (2917 / 7343 Metric), and physical dimensions (7.30 × 4.30 × 1.90 mm). The primary difference is product status (Active versus Obsolete) and RoHS compliance (ROHS3 versus non-compliant).

Q: What is the difference between the packaging formats listed for the substitute parts?

A: T520V337M004ATE012 is supplied in Cut Tape (CT) & Digi-Reel® format, suitable for both manual component placement and automated pick-and-place equipment. T520V337M004ATE0124539, T520V337M004ATE0127333, and T520V337M004ATE012E009 are supplied in Tape & Reel (TR) format, optimized for high-volume automated assembly. The electrical and mechanical specifications are identical across all packaging formats.

Q: Are all substitute parts ROHS3 compliant?

Q: Do the substitute parts have the same moisture sensitivity level as the original part?

A: Yes. All substitute parts maintain MSL 3 (168 Hours) rating, identical to the original T520V337M004ASE012. Handling and storage procedures remain unchanged.

Q: Which substitute part should be selected for new design implementations?

A: T520V337M004ATE012 is the recommended choice for new designs due to its direct equivalence, active product status, ROHS3 compliance, and flexible packaging format (Cut Tape & Digi-Reel®). For high-volume production environments, T520V337M004ATE0124539, T520V337M004ATE0127333, or T520V337M004ATE012E009 are suitable alternatives with Tape & Reel packaging.

Q: Are there any electrical performance differences between the substitute parts?

A: No. All substitute parts are parametrically identical with respect to capacitance (330 µF), voltage rating (4 V), tolerance (±20%), ESR (12 mOhm @ 100 kHz), operating temperature range (-55°C to 105°C), and lifetime rating (2000 Hours @ 105°C).
