SPA680M06R Equivalent & Substitute Parts

Part Overview

The SPA680M06R is a 68 µF, 6.3 V aluminum-polymer surface mount capacitor manufactured by Cornell Dubilier Electronics (CDE) in the 2917 (7343 Metric) package. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support, board repairs, and production continuity. The part delivers 9 mOhm equivalent series resistance with a 1000-hour lifetime rating at 105°C and operates across the temperature range of -40°C to 105°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPA680M06R is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 68 µF (exact match required)
• Rated voltage: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR: 9 mOhm (exact match required)
• Component type: Aluminum-polymer capacitor (exact match required)

Mechanical Parameters:

• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Physical dimensions: 0.287" L x 0.169" W (7.30mm x 4.30mm) (exact match required)

Compliance Parameters:

• RoHS3 compliance (required for regulatory alignment)

The substitute part EEF-SX0J680R meets all critical electrical and mechanical parameters. Variations in lifetime rating, operating temperature range, and packaging format (Tape & Reel versus bulk) do not disqualify substitution when the core functional parameters align.

Parameter Comparison

Engineering Selection Recommendations

The EEF-SX0J680R from Panasonic Electronic Components is a direct functional equivalent to the obsolete SPA680M06R. Both components share identical electrical specifications (68 µF, 6.3 V, ±20% tolerance, 9 mOhm ESR) and mechanical form factor (2917 package, surface mount, 7.30mm x 4.30mm footprint).

The Panasonic substitute offers extended operational advantages: a 2000-hour lifetime at 105°C (versus 1000 hours for the CDE part) and an expanded operating temperature range of -55°C to 105°C (versus -40°C to 105°C). The maximum seated height of 0.079" (2.00mm) for the substitute is 0.004" taller than the original 0.075" (1.90mm), which remains within typical PCB design tolerances for surface mount components.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The EEF-SX0J680R is currently in active production with established supply availability, making it the appropriate selection for new designs, repairs, and production continuity where the SPA680M06R is no longer obtainable.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0J680R be used as a direct replacement for the SPA680M06R on existing PCBs?

A: Yes. Both components share identical electrical parameters (68 µF, 6.3 V, 9 mOhm ESR) and the same 2917 (7343 Metric) surface mount package with matching 7.30mm x 4.30mm footprints. The 0.004" difference in maximum seated height (1.90mm versus 2.00mm) does not affect PCB assembly or clearance in standard designs.

Q: What is the primary reason for substitution?

A: The SPA680M06R is classified as obsolete. The EEF-SX0J680R is an active production part from Panasonic that meets all functional and mechanical requirements, ensuring supply continuity and design support.

Q: Are there differences in performance between these two parts?

A: The substitute part exceeds the original specifications in two areas: lifetime rating (2000 hours at 105°C versus 1000 hours) and operating temperature range (-55°C to 105°C versus -40°C to 105°C). These differences represent performance enhancements with no negative impact on compatibility.

Q: What packaging formats are available for the substitute part?

A: The EEF-SX0J680R is supplied in Tape & Reel (TR) format. The original SPA680M06R was supplied in bulk packaging. Tape & Reel format is standard for high-volume surface mount assembly and does not affect component functionality.

Q: Are both parts RoHS compliant?

A: Yes. Both the SPA680M06R and EEF-SX0J680R are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Can the EEF-SX0J680R be used in applications requiring the full -40°C to 105°C temperature range of the original part?

A: Yes. The substitute part operates across -55°C to 105°C, which fully encompasses the original -40°C to 105°C range and extends capability to lower temperatures.
