Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSBLA455KEC8-B0 is determined by strict equivalence across the following critical parameters:

• Frequency: 455 kHz (exact match required)
• Frequency Stability: ±0.3% (determines circuit performance tolerance)
• Operating Temperature Range: -20°C to 80°C (defines environmental compatibility)
• Mounting Type: Through Hole (ensures mechanical compatibility with existing PCB layouts)
• Package / Case: Radial, Box - 2 Lead, 5.00mm Pitch (guarantees physical fit and lead spacing)
• Physical Dimensions: 7.00mm L x 3.50mm W x 9.00mm H (confirms board-level compatibility)

The ZTB455E from ECS Inc. meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The ZTB455E is the qualified substitute for the CSBLA455KEC8-B0. Both components are classified as legacy products (Obsolete and Not For New Designs respectively), indicating limited future availability. The ZTB455E maintains full electrical and mechanical equivalence across all specified parameters.

For applications requiring the 455 kHz ceramic resonator with the specified performance envelope, the ZTB455E provides direct compatibility with existing circuit designs and PCB layouts. Current inventory availability of the ZTB455E (3400 pcs) exceeds that of the original part (1018 pcs), supporting near-term production requirements.

Both components carry identical regulatory compliance: REACH Unaffected, EAR99 classification, and HTSUS code 8548.00.0000.

Frequently Asked Questions (FAQ)

Q: Can the ZTB455E be used as a direct replacement for the CSBLA455KEC8-B0?

A: Yes. The ZTB455E meets all electrical and mechanical specifications of the CSBLA455KEC8-B0, including frequency, stability, temperature range, impedance, and physical dimensions. No circuit modifications are required.

Q: Are there any differences in packaging between these parts?

A: No. Both components use identical packaging: Radial, Box - 2 Lead configuration with 5.00mm pitch and matching physical dimensions of 7.00mm L x 3.50mm W x 9.00mm H.

Q: What is the significance of the "Not For New Designs" status of the ZTB455E?
