Engineering Selection Recommendations

Direct Substitutes (50V Rating): Parts SR155E104MAA, SR155E104MAR, SR205E104MAA, SR205E104MAR, SR205E104MART, SR205E104MARTR1, SR295E104MAR, SR295E104MARTR1, and SR295E104MARTR2 are direct electrical equivalents with identical capacitance, voltage, tolerance, and temperature coefficient specifications. Selection among these parts depends on PCB layout requirements and packaging format availability.

Dimensional Considerations:

SR155E series parts feature reduced footprint (0.150" x 0.100") suitable for space-constrained applications
SR205E and SR295E series maintain the 0.200" x 0.125" footprint compatible with standard PCB layouts
Height variation between parts (0.150" to 0.250" seated height) affects clearance requirements

Lead Configuration:

Straight lead variants (SR205E104MAA, SR205E104MAR, SR205E104MART) provide consistent insertion depth
Formed lead variants (SR295E104MAR, SR295E104MARTR1, SR295E104MARTR2) accommodate pre-formed lead spacing
All variants maintain 0.100" (2.54mm) lead spacing for standard through-hole PCB patterns

Packaging Format:

Bulk packaging suits high-volume assembly operations
Cut tape (CT) packaging accommodates automated pick-and-place equipment

Voltage Upgrade Option: SR201E104MAA provides 100V rating with identical physical dimensions and lead spacing, enabling use in higher voltage applications while maintaining backward compatibility with PCB layouts designed for 50V parts.

All listed parts maintain ROHS3 compliance and REACH unaffected status consistent with the primary part.

Frequently Asked Questions (FAQ)

Q: Can SR155E104MAA or SR155E104MAR be used as direct replacements for SR295E104MAT?

A: Electrically yes, but with physical constraints. The SR155E series has reduced dimensions (0.150" x 0.100" vs. 0.200" x 0.125") and lower seated height (0.150" vs. 0.250"). PCB layout must accommodate the smaller footprint and lead positioning.

Q: What is the difference between formed leads and straight leads?

A: Formed leads (SR295E series) arrive pre-bent for specific spacing. Straight leads (SR205E series) require manual forming or insertion into PCB holes with standard spacing. Both maintain 0.100" (2.54mm) lead spacing.

Q: Can SR201E104MAA (100V) replace SR295E104MAT (50V)?

A: Yes. The 100V part is electrically compatible and physically identical in footprint and lead spacing. Higher voltage rating provides additional design margin in applications where 50V is sufficient.

Q: What packaging format should be selected for automated assembly?

A: Cut Tape (CT) packaging variants (SR205E104MARTR1, SR295E104MARTR1, SR295E104MARTR2) are designed for automated pick-and-place equipment. Bulk packaging is suitable for manual or semi-automated assembly.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts maintain ROHS3 compliance and REACH unaffected status.

Q: Does lead style affect electrical performance?

A: No. Formed leads, straight leads, and kinked leads are mechanical variations only. Electrical performance remains identical across all lead style variants.
