Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECA-2EM010B is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance: 1 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime @ Temperature: 2000 Hrs @ 85°C (exact match required)
• Operating Temperature Range: -25°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Size / Dimension: 0.248" Dia (6.30mm) (exact match required)
• Height - Seated (Max): 0.480" (12.20mm) (exact match required)

Allowable Variation:

• Voltage - Rated: May be equal or higher than 250 V
• Lead Spacing: May vary if PCB layout permits
• Packaging Format: Cut Tape or Bulk acceptable

Substitute parts must maintain all electrical specifications and physical dimensions while accommodating voltage rating upgrades and packaging format changes.

Parameter Comparison

Engineering Selection Recommendations

ECA-2GM010B (Upgrade Substitute): This part is suitable for direct substitution in applications where the circuit design permits a higher voltage rating. The 400 V rating provides increased voltage margin over the original 250 V specification. All electrical parameters including capacitance, tolerance, and thermal lifetime remain identical. Physical dimensions and mounting configuration are fully compatible. Both parts are Active status with ROHS3 compliance. This substitute is appropriate for designs requiring enhanced voltage headroom or when higher-rated inventory is preferred for standardization.

ECA-2EM010 (Similar Substitute): This part maintains identical electrical specifications and physical dimensions as the main part. The primary difference is the lead spacing of 0.098" (2.50mm) versus 0.197" (5.00mm) on the main part, and packaging format change from Cut Tape to Bulk. This substitute is suitable only if PCB layout accommodates the reduced lead spacing. Both parts are Active status with ROHS3 compliance. This substitute is appropriate for applications where lead spacing adjustment is feasible and bulk packaging is acceptable.

Frequently Asked Questions (FAQ)

Q: Can ECA-2GM010B replace ECA-2EM010B in any application? A: Yes. The ECA-2GM010B has a higher voltage rating (400 V vs. 250 V) while maintaining identical capacitance, tolerance, thermal lifetime, and physical dimensions. Higher voltage ratings do not degrade performance in lower-voltage applications.

Q: What is the key difference between ECA-2EM010B and ECA-2EM010? A: The primary difference is lead spacing: ECA-2EM010B has 0.197" (5.00mm) spacing while ECA-2EM010 has 0.098" (2.50mm) spacing. Packaging format also differs (Cut Tape vs. Bulk). All electrical specifications are identical.

Q: Is ECA-2EM010 compatible with ECA-2EM010B PCB layouts? A: Compatibility depends on PCB hole spacing. If the PCB is designed for 0.197" (5.00mm) lead spacing, ECA-2EM010 with 0.098" (2.50mm) spacing will not fit without layout modification.

Q: Are all three parts ROHS3 compliant? A: Yes. ECA-2EM010B, ECA-2GM010B, and ECA-2EM010 are all ROHS3 compliant.

Q: Can I use ECA-2EM010 if my design requires Cut Tape packaging? A: No. ECA-2EM010 is supplied in Bulk packaging only. For Cut Tape format, use ECA-2EM010B or ECA-2GM010B.

Q: What is the ripple current difference between ECA-2EM010B and ECA-2GM010B? A: ECA-2EM010B supports 34 mA @ 120 Hz and 57.8 mA @ 10 kHz. ECA-2GM010B supports 32 mA @ 120 Hz and 54.4 mA @ 10 kHz. Both values are within acceptable operating ranges for general-purpose applications.
