EFO-S6004E5 Equivalent & Substitute Parts

Part Overview

The EFO-S6004E5 is a 6 MHz ceramic resonator with built-in 33 pF capacitor manufactured by Panasonic Electronic Components. This surface mount component operates across -20°C to 80°C with ±0.2% frequency stability and ±0.5% frequency tolerance. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of ceramic resonators is determined by matching the following critical parameters:

• Frequency: Must be 6 MHz to maintain system timing requirements
• Operating Temperature Range: Must support -20°C to 80°C minimum
• Mounting Type: Must be surface mount compatible
• Package Configuration: Must be 3-SMD, non-standard format
• Built-in Capacitance: Acceptable variance within ±3 pF of the original 33 pF specification
• Frequency Stability & Tolerance: Must meet or exceed ±0.2% stability and ±0.5% tolerance requirements

The ECS-SR1-6.00-B-TR meets these substitution criteria with a 30 pF built-in capacitor (within acceptable tolerance variance), matching frequency, temperature range, mounting type, and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The ECS-SR1-6.00-B-TR serves as a direct functional equivalent for the obsolete EFO-S6004E5. Both components share identical frequency, operating temperature range, mounting type, and package configuration. The 3 pF capacitance difference (33 pF vs. 30 pF) falls within acceptable substitution parameters for ceramic resonator applications.

The ECS-SR1-6.00-B-TR carries Last Time Buy status, indicating limited future availability. Designs currently using the EFO-S6004E5 should transition to this substitute while inventory remains available. The substitute is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the ECS-SR1-6.00-B-TR directly replace the EFO-S6004E5 without circuit modifications?

A: Yes. Both components operate at 6 MHz with identical temperature ranges and mounting specifications. The 3 pF capacitance difference is within acceptable tolerance for ceramic resonator substitution in standard applications.

Q: What is the significance of the capacitance difference between 33 pF and 30 pF?

A: Built-in capacitance in ceramic resonators affects frequency stability and load characteristics. A 3 pF variance represents approximately 9% difference. Circuit validation is necessary to confirm performance equivalence in your specific application.

Q: Why is the ECS-SR1-6.00-B-TR listed as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has announced end-of-life production. Existing inventory will be depleted without replenishment. Procurement should prioritize securing adequate stock for current and near-term production needs.

Q: Are there dimensional differences between these components?

A: Yes. The EFO-S6004E5 measures 7.80mm L × 3.20mm W × 1.60mm H, while the ECS-SR1-6.00-B-TR measures 7.50mm L × 3.30mm W × 2.20mm H. Both are 3-SMD non-standard packages. Verify PCB layout compatibility before implementation.

Q: What packaging formats are available for each part?

A: The EFO-S6004E5 is supplied in bulk packaging. The ECS-SR1-6.00-B-TR is supplied in Tape & Reel (TR) format, standard for automated assembly processes.
