Substitute Part Grouping Explanation

Substitution of the EEE-HAA101WAP is determined by the following critical parameters:

Electrical Compatibility: Capacitance (100 µF) and tolerance (±20%) must remain constant. Voltage rating may be increased to 16 V as this provides backward compatibility in circuits designed for 10 V operation.

Thermal Performance: Lifetime at 105°C may be extended from 1000 hours to 2000 or 5000 hours without affecting circuit functionality, provided the operating temperature range remains -40°C to 105°C.

Physical Compatibility: Package type (Radial, Can - SMD), mounting type (Surface Mount), and land size (0.260" L x 0.260" W / 6.60mm x 6.60mm) must match to ensure PCB compatibility. Physical dimensions (diameter and height) may vary slightly within the same package family.

Regulatory Compliance: All substitute parts must maintain AEC-Q200 automotive certification and ROHS3 compliance status.

Substitute parts are grouped into two categories:

Upgrade Substitutes (16 V Rating): EEE-FP1C101AP, EEE-HA1C101WP, EEE-HAC101WAP, and EEE-HBC101UAP provide higher voltage ratings (16 V) while maintaining identical capacitance, tolerance, and package specifications. These are direct functional upgrades suitable for applications where voltage margin is beneficial.

Similar Substitutes (10 V Rating, Alternate Packaging): EEE-FC1A101P, EEE-HA1A101AP, EEE-HA1A101P, EEE-HB1A101AP, EEE-HBA101UAP, and EEE-HD1A101AP maintain the 10 V rating but may differ in physical dimensions, lifetime ratings, or packaging format (Tape & Reel versus Cut Tape).

Engineering Selection Recommendations

For Direct Replacement (Same Voltage, Same Lifetime): EEE-HAC101WAP is the primary recommendation. It maintains identical electrical specifications (100 µF, 10 V, ±20%), identical physical dimensions (0.248" diameter, 0.213" height), identical land size (0.260" x 0.260"), and identical lifetime (1000 hours at 105°C). Product status is Active, ensuring long-term availability. ROHS3 compliance and AEC-Q200 certification are maintained.

For Voltage Upgrade (Higher Margin): EEE-HAC101WAP (16 V) or EEE-HBC101UAP (16 V, 2000 Hrs) are suitable when circuit design permits higher voltage ratings. Both maintain identical physical dimensions and land sizes. EEE-HBC101UAP provides extended lifetime (2000 hours) at the cost of slightly increased height (0.228" versus 0.213"). Both are Active products with ROHS3 compliance.

For Extended Lifetime: EEE-HBC101UAP (2000 hours at 105°C, 16 V) or EEE-HD1A101AP (5000 hours at 105°C, 10 V) are appropriate when thermal stress endurance is critical. EEE-HD1A101AP maintains the 10 V rating but requires larger physical footprint (0.315" diameter, 0.244" height) and different land size (0.327" x 0.327"), necessitating PCB redesign.

Parts to Avoid for New Designs: EEE-HA1C101WP, EEE-FC1A101P, EEE-HA1A101AP, and EEE-HA1A101P are marked "Not For New Designs" and should not be selected for new product development despite electrical compatibility.

Packaging Consideration: EEE-HBA101UAP is available in Cut Tape & Digi-Reel format instead of standard Tape & Reel, suitable for lower-volume or mixed-component assembly operations.

Frequently Asked Questions (FAQ)

Q: Can EEE-HAC101WAP replace EEE-HAA101WAP directly on the PCB?

A: Yes. Both parts have identical physical dimensions (0.248" diameter, 0.213" height), identical land size (0.260" x 0.260"), and identical electrical specifications (100 µF, 10 V, ±20%). No PCB modification is required.

Q: What is the advantage of using a 16 V rated capacitor instead of 10 V?

A: A 16 V rated capacitor provides additional voltage margin in the circuit. If the circuit operates at 10 V nominal, a 16 V capacitor offers 60% additional headroom against voltage transients or supply variations. This does not change circuit functionality but may improve reliability in applications with voltage spikes.

Q: Can I use EEE-HD1A101AP as a direct replacement?

A: No. EEE-HD1A101AP has different physical dimensions (0.315" diameter, 0.244" height) and different land size (0.327" x 0.327"). PCB redesign is required. However, it offers 5000-hour lifetime at 105°C compared to 1000 hours, suitable for high-reliability applications.

Q: Why are some parts marked "Not For New Designs"?

A: Parts marked "Not For New Designs" are in end-of-life status. While electrically compatible, they may have limited future availability. New product designs should use Active status parts such as EEE-HAC101WAP, EEE-HBC101UAP, or EEE-HB1A101AP.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel packaging is standard for high-volume automated assembly. Cut Tape & Digi-Reel is used for lower volumes or mixed-component orders where individual component selection is required. Electrical and physical specifications remain identical; only the delivery format differs.

Q: Is EEE-HBA101UAP compatible with my PCB designed for EEE-HAA101WAP?

A: Yes. EEE-HBA101UAP has identical physical dimensions (0.248" diameter), identical land size (0.260" x 0.260"), and identical electrical specifications (100 µF, 10 V, ±20%). The only difference is packaging format (Cut Tape & Digi-Reel instead of Tape & Reel) and slightly increased height (0.228" versus 0.213"), which does not affect PCB compatibility.

Q: Can I substitute EEE-HA1A101AP for EEE-HAA101WAP?

A: No. EEE-HA1A101AP has different physical dimensions (0.315" diameter, 0.244" height) and different land size (0.327" x 0.327"). Additionally, it is marked "Not For New Designs." PCB redesign would be required, and this part should not be used for new product development.
