Substitute Part Grouping Explanation

Substitution eligibility for the ECA-2CM2R2B is determined by strict equivalence across the following parameters:

Capacitance value: 2.2 µF (exact match required)
Voltage rating: 160 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime specification: 2000 Hrs @ 85°C (exact match required)
Operating temperature range: -25°C ~ 85°C (exact match required)
Polarization: Polar (exact match required)
Package type: Radial, Can (exact match required)
Mounting type: Through Hole (exact match required)
Physical dimensions: 0.248" Dia (6.30mm) and 0.480" (12.20mm) height (exact match required)
Series: M-A (exact match required)
Compliance certifications: ROHS3 Compliant, REACH Unaffected (exact match required)

The substitute part ECA-2CM2R2 meets all electrical and mechanical criteria for direct substitution. The only difference is packaging format (Bulk versus Cut Tape), which does not affect component functionality or circuit performance.

Engineering Selection Recommendations

Both ECA-2CM2R2B and ECA-2CM2R2 are Active products with identical ROHS3 compliance and REACH unaffected certification status. Selection between these parts should be based on packaging requirements and lead spacing compatibility with the PCB design.

The ECA-2CM2R2B features 0.197" (5.00mm) lead spacing and is supplied in Cut Tape format, suitable for automated assembly processes. The ECA-2CM2R2 features 0.098" (2.50mm) lead spacing and is supplied in Bulk format, suitable for manual assembly or alternative handling methods.

PCB footprint design determines lead spacing compatibility. Verify that the target PCB accommodates the lead spacing of the selected part before implementation. Both parts deliver identical electrical performance and thermal characteristics across all specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can ECA-2CM2R2 replace ECA-2CM2R2B in all applications?

A: Electrical and thermal performance are identical. Substitution is valid provided the PCB footprint accommodates the 0.098" (2.50mm) lead spacing of ECA-2CM2R2. The ECA-2CM2R2B uses 0.197" (5.00mm) lead spacing. Verify footprint compatibility before substitution.

Q: What is the difference between Cut Tape and Bulk packaging?

A: Cut Tape (CT) packaging is used for automated pick-and-place assembly processes. Bulk packaging is used for manual assembly or alternative component handling. Both packaging formats contain identical components with the same electrical specifications.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both ECA-2CM2R2B and ECA-2CM2R2 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Do these parts have identical ripple current ratings?

A: Yes. Both parts are rated for 53 mA ripple current at 120 Hz and 90.1 mA ripple current at 10 kHz. Ripple current performance is identical across both frequency ranges.

Q: What is the lead spacing difference and why does it matter?

A: ECA-2CM2R2B has 0.197" (5.00mm) lead spacing, while ECA-2CM2R2 has 0.098" (2.50mm) lead spacing. Lead spacing determines the distance between component leads on the PCB. The PCB footprint must match the lead spacing of the selected part for proper mechanical fit and electrical connection.
