Substitute Part Grouping Explanation

Substitution for the B41002A2107M is determined by the following critical parameters:

Capacitance: 100 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 6.3 V minimum (equal or higher voltage ratings are acceptable)
Polarization: Polar (exact match required)
Lead Spacing: 0.098" (2.50mm) (exact match required)
Size / Dimension: 0.248" Dia (6.30mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)

Substitute parts are classified into two categories:

Upgrade Substitutes (10ZLG100MEFC6.3X7, 16ML100MEFC6.3X7): These parts maintain identical capacitance, tolerance, lead spacing, and physical dimensions while offering higher voltage ratings (10 V or 16 V) and improved thermal performance characteristics. These are direct mechanical and electrical upgrades suitable for applications where the original 6.3 V rating is sufficient but enhanced reliability is desired.

Parametric Equivalent (107RSS6R3M): This part matches the B41002A2107M in all critical parameters including voltage rating, capacitance, tolerance, and physical dimensions. It is manufactured by Cornell Dubilier / Illinois Capacitor and maintains identical electrical and mechanical specifications with active product status.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent):

The 107RSS6R3M is the recommended parametric equivalent for the B41002A2107M. Both parts share identical electrical specifications (100 µF, ±20%, 6.3 V), thermal ratings (1000 Hrs @ 85°C), and physical dimensions. The 107RSS6R3M holds active product status, ensuring long-term availability and supply chain continuity. Both parts are ROHS3 compliant and suitable for applications requiring no design modification.

For Upgraded Performance:

The 10ZLG100MEFC6.3X7 and 16ML100MEFC6.3X7 are upgrade substitutes offering higher voltage ratings and extended thermal performance. The 16ML100MEFC6.3X7 provides the highest reliability with 5000 hours at 105°C and 16 V rating. These parts maintain identical lead spacing and base dimensions, with the 10ZLG100MEFC6.3X7 introducing a maximum height increase of 0.020" (0.50mm). Both upgrade substitutes are ROHS3 compliant. Selection between these options depends on application voltage headroom requirements and thermal environment specifications.

Frequently Asked Questions (FAQ)

Q: Can the 107RSS6R3M be used as a direct replacement for the B41002A2107M?

A: Yes. The 107RSS6R3M is a parametric equivalent with matching capacitance (100 µF), tolerance (±20%), voltage rating (6.3 V), and physical dimensions. Both parts are rated for 1000 hours at 85°C and use identical lead spacing (0.098" / 2.50mm) and mounting configuration. The 107RSS6R3M is currently in active production status.

Q: What is the difference between the upgrade substitutes and the parametric equivalent?

A: The 107RSS6R3M matches the B41002A2107M exactly in voltage rating and thermal specifications. The upgrade substitutes (10ZLG100MEFC6.3X7 and 16ML100MEFC6.3X7) provide higher voltage ratings (10 V and 16 V respectively) and improved thermal performance (1000 Hrs @ 105°C and 5000 Hrs @ 105°C). All three alternatives maintain the same capacitance, tolerance, lead spacing, and base physical dimensions.

Q: Are there any height differences between these parts?

A: The B41002A2107M, 16ML100MEFC6.3X7, and 107RSS6R3M all have a maximum seated height of 0.315" (8.00mm). The 10ZLG100MEFC6.3X7 has a maximum seated height of 0.335" (8.50mm), representing a 0.020" (0.50mm) increase. This difference must be verified against PCB layout constraints before selection.

Q: Are all substitute parts RoHS compliant?

A: Yes. The B41002A2107M, 10ZLG100MEFC6.3X7, 16ML100MEFC6.3X7, and 107RSS6R3M are all ROHS3 compliant.
