Key Parameters

Substitute Part Grouping Explanation

Substitution of the VSOP58438 is determined by the following critical parameters:

• B.P.F. Center Frequency: 38.0kHz (primary functional requirement)
• Mounting Type: Surface Mount (physical compatibility)
• Operating Temperature Range: -25°C ~ 85°C (environmental compatibility)
• Supply Voltage Range: Must accommodate the original 2.7 V ~ 5.5 V specification
• RoHS3 Compliance: Required for regulatory alignment
• MSL Rating: 1 (Unlimited) for handling compatibility

The VSOP38338 meets all substitution criteria as an active product offering identical center frequency, compatible mounting, matching temperature range, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The VSOP38338 is the direct substitute for the obsolete VSOP58438. Both components are manufactured by Vishay Semiconductor Opto Division and maintain identical 38.0kHz center frequency operation, surface mount packaging, and operating temperature specifications. The VSOP38338 is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) ratings, supporting equivalent handling and environmental requirements. The VSOP38338 operates within a marginally lower minimum supply voltage (2.5 V versus 2.7 V) and exhibits higher supply current consumption (3 mA versus 850 µA), both of which are acceptable design considerations for standard 38.0kHz remote receiver applications.

Frequently Asked Questions (FAQ)

Q: Can the VSOP38338 directly replace the VSOP58438 in existing designs?

A: Yes. Both components share identical 38.0kHz center frequency, surface mount configuration, and operating temperature range. The VSOP38338 is the manufacturer-recommended substitute for the obsolete VSOP58438.

Q: What are the key differences between these parts?

A: The primary differences are product status (VSOP58438 is obsolete; VSOP38338 is active), supply voltage minimum (2.7 V versus 2.5 V), and supply current (850 µA versus 3 mA). The VSOP38338 represents the current production equivalent.

Q: Are there packaging differences?

A: The VSOP38338 is specified as Tape & Reel (TR) packaging. Both components are surface mount devices with compatible footprints for standard PCB assembly.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the VSOP58438 and VSOP38338 are ROHS3 compliant with MSL 1 (Unlimited) ratings, supporting equivalent regulatory and handling requirements.

Q: What should be considered when transitioning from VSOP58438 to VSOP38338?

A: Verify that the circuit design accommodates the VSOP38338's 2.5 V minimum supply voltage and 3 mA maximum supply current. Both parameters are compatible with standard 38.0kHz remote receiver circuit topologies.
