Key Parameters

Substitute Part Grouping Explanation

The OC25SC65-04 is identified as a substitute for the OC16SC00-04 based on the following substitution criteria:

Matching Parameters:

• Type: Both are tweeter speakers
• Port Location: Both feature top-mounted configuration
• Shape: Both are round design
• Material - Cone: Both use cloth construction
• Material - Magnet: Both employ neodymium magnets
• Termination: Both use solder eyelet(s)
• RoHS Status: Both are ROHS3 compliant
• Frequency Range: Both cover the upper audio spectrum with overlap (1.3 kHz ~ 20 kHz vs. 2.5 kHz ~ 20 kHz)

Differing Parameters:

• Impedance: 3.2 Ohms (substitute) vs. 4.33 Ohms (main part)
• Power - Rated: 25 W (substitute) vs. 100 W (main part)
• Efficiency - dBA: 89.20 (substitute) vs. 82.80 (main part)
• Size / Dimension: 1.280" Dia (32.50mm) vs. 1.024" Dia (26.00mm)
• Product Status: Active (substitute) vs. Obsolete (main part)

Parameter Comparison

Engineering Selection Recommendations

The OC25SC65-04 is available as an active product from Peerless by Tymphany, providing supply continuity for the obsolete OC16SC00-04. Both components maintain ROHS3 compliance and identical termination specifications, supporting direct integration into existing assembly processes.

Selection between these components depends on system-level requirements. The OC16SC00-04 operates at higher impedance (4.33 Ohms) and power rating (100 W) with lower efficiency (82.80 dBA). The OC25SC65-04 operates at lower impedance (3.2 Ohms) and reduced power rating (25 W) with higher efficiency (89.20 dBA). The substitute component also features a larger diameter (32.50mm vs. 26.00mm) and extended lower frequency response (1.3 kHz vs. 2.5 kHz).

Frequently Asked Questions (FAQ)

Q: Can the OC25SC65-04 directly replace the OC16SC00-04 in existing designs?

A: Direct replacement requires system-level evaluation. The impedance difference (3.2 Ohms vs. 4.33 Ohms) and power rating difference (25 W vs. 100 W) necessitate crossover and amplifier compatibility verification. The larger physical dimension (32.50mm vs. 26.00mm) must be confirmed against mechanical mounting constraints.

Q: What are the key differences in electrical performance?

A: The OC25SC65-04 provides higher efficiency (89.20 dBA vs. 82.80 dBA) and extended lower frequency response (1.3 kHz vs. 2.5 kHz). However, it operates at reduced power capacity (25 W vs. 100 W) and lower impedance (3.2 Ohms vs. 4.33 Ohms).

Q: Are both components RoHS compliant?

A: Yes, both the OC16SC00-04 and OC25SC65-04 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the physical size difference?

A: The OC16SC00-04 has a diameter of 1.024" (26.00mm), while the OC25SC65-04 has a diameter of 1.280" (32.50mm). Mounting cavity and enclosure dimensions must accommodate this 6.25mm increase in diameter.

Q: Do both components use identical termination?

A: Yes, both components feature solder eyelet(s) termination, supporting equivalent assembly and soldering processes.
