Substitute Part Grouping Explanation

Substitution between TE1209 and TE1209-E3 is based on electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical selection criteria: capacitance value of 50 µF, rated voltage of 25 V, tolerance band of -10% to +75%, operating temperature range of -40°C to 105°C, and thermal lifetime rating of 2000 hours at 85°C. Physical dimensions, package configuration (axial, can), and through-hole mounting type are identical. The primary distinction between these parts is regulatory compliance status, with TE1209-E3 offering ROHS3 compliance compared to the non-compliant status of the original TE1209.

Parameter Comparison

Engineering Selection Recommendations

TE1209-E3 is the preferred substitute for new designs and applications subject to RoHS3 regulatory requirements. Both parts maintain identical electrical performance and physical compatibility, ensuring direct board-level substitution without circuit redesign. TE1209-E3 offers improved regulatory compliance status while maintaining the same thermal performance characteristics and operating specifications. Selection between these parts should be based on applicable regulatory requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can TE1209-E3 replace TE1209 in existing designs? A: Yes. Both parts are electrically and mechanically identical, with identical capacitance, voltage rating, tolerance, temperature range, and physical dimensions. Direct substitution is possible without circuit modification.

Q: What is the primary difference between TE1209 and TE1209-E3? A: The primary difference is RoHS compliance status. TE1209-E3 is ROHS3 compliant, while TE1209 is non-compliant. All electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical between these parts? A: Yes. Both parts share identical dimensions of 0.315" diameter by 0.807" length (8.00mm x 20.50mm) and use the same axial, can package configuration with through-hole mounting.

Q: Do these parts have the same thermal performance? A: Yes. Both parts are rated for 2000 hours at 85°C and operate across the same temperature range of -40°C to 105°C.

Q: Which part should be selected for new production? A: TE1209-E3 is recommended for new designs due to ROHS3 compliance certification. Both parts are active products with adequate inventory availability.
