Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, confirming ongoing manufacturing support and regulatory alignment.

B41888C4687M000 (EPCOS - TDK Electronics): This substitute carries AEC-Q200 automotive qualification and demonstrates superior performance characteristics including lower ESR (64 mOhm @ 10kHz) and extended lifetime (7000 Hrs @ 105°C). The height specification is 0.669" (17.00mm), which is 0.020" lower than the original part. This part is suitable for applications requiring enhanced reliability and automotive-grade certification.

ELXZ160ELL681MJ16S (Chemi-Con): This substitute also carries AEC-Q200 automotive qualification with a lifetime rating of 5000 Hrs @ 105°C. The height specification matches the original part at 0.689" (17.50mm). Ripple current capability at 100 kHz is 1.05 A. This part provides a direct mechanical fit with the original 687KXM016MLQ.

Both substitute parts are electrically and mechanically compatible with the 687KXM016MLQ within the defined parameter tolerances for this capacitor category.

Frequently Asked Questions (FAQ)

Q: Can B41888C4687M000 be used as a direct replacement for 687KXM016MLQ in PCB assembly?

A: B41888C4687M000 is electrically compatible. The height difference of 0.020" (0.50mm) must be evaluated against PCB clearance requirements and enclosure constraints. All other mechanical parameters including lead spacing, diameter, and mounting type are identical.

Q: What is the significance of the ESR difference between the original part and substitutes?

A: ESR values are measured at different frequencies (120Hz for 687KXM016MLQ, 10kHz for B41888C4687M000). Lower ESR generally indicates better high-frequency performance and reduced heat generation. The substitute parts demonstrate improved ESR characteristics, which is beneficial for ripple current applications.

Q: Are both substitute parts suitable for automotive applications?

A: Both B41888C4687M000 and ELXZ160ELL681MJ16S carry AEC-Q200 automotive qualification. The original 687KXM016MLQ is specified for general purpose applications without automotive certification. Substitutes may be used in automotive contexts where AEC-Q200 compliance is required.

Q: How do the ripple current ratings affect component selection?

A: Ripple current ratings indicate the maximum AC current the capacitor can handle at specified frequencies. B41888C4687M000 (1.24 A @ 100 kHz) and ELXZ160ELL681MJ16S (1.05 A @ 100 kHz) both exceed the original part's rating (880 mA @ 100 kHz), providing additional margin for high-frequency applications.

Q: What is the impact of different lifetime ratings?

A: Lifetime specifications indicate expected operational duration at maximum rated temperature (105°C). B41888C4687M000 (7000 Hrs) and ELXZ160ELL681MJ16S (5000 Hrs) both exceed the original part's rating (4000 Hrs), suggesting extended service life under thermal stress conditions.

Q: Are there any packaging or inventory considerations?

A: B41888C4687M000 is available in bulk packaging with 23,823 pieces in stock. ELXZ160ELL681MJ16S is available in bulk packaging with 2,573 pieces in stock. The original 687KXM016MLQ has 956 pieces in stock. Packaging format is consistent across all three parts (Bulk or standard through-hole compatible).
