Substitute Part Grouping Explanation

Substitution of the Parallax Inc. 28054 is determined by the following critical parameters:

Primary Substitution Criteria:

• Optical sensor category classification
• Sensing distance range capability (10 ~ 12000 cm minimum)
• Output type compatibility (Analog output as baseline requirement)
• Supply voltage range (4.5 ~ 5.5V)
• Operating temperature range (0°C ~ 40°C)
• RoHS compliance status

The Parallax Inc. 28058 qualifies as a substitute based on shared manufacturer origin, optical sensor classification, analog output capability, matching supply voltage specification, and identical operating temperature range. Both components maintain RoHS compliance and MSL Level 1 rating.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

The Parallax Inc. 28058 serves as an active-status alternative to the obsolete 28054. Both components share identical supply voltage specifications (4.5 ~ 5.5V) and operating temperature ranges (0°C ~ 40°C), ensuring electrical compatibility in existing circuit designs. Both maintain RoHS compliance, satisfying regulatory requirements for new production.

Operational Considerations:

The 28058 operates at 250 mA supply current compared to the 28054's 200 mA specification, representing a 50 mA increase in power consumption. The sensing distance of the 28058 (100 m / 10000 cm) overlaps substantially with the 28054's range (10 ~ 12000 cm), with the 28054 providing extended range capability to 12000 cm.

The 28054 provides multiple output interfaces (Analog, I2C, SPI), while the 28058 provides Analog output only. Applications requiring I2C or SPI protocols must implement alternative solutions or interface conversion logic.

Frequently Asked Questions (FAQ)

Q: Can the Parallax Inc. 28058 directly replace the 28054 in all applications?

A: The 28058 provides direct electrical substitution for applications utilizing the Analog output interface. Applications dependent on I2C or SPI output protocols require alternative component selection or interface adaptation.

Q: What is the primary difference in sensing distance between these components?

A: The 28054 specifies a maximum sensing distance of 12000 cm, while the 28058 specifies 10000 cm (100 m). For applications requiring distance measurement beyond 10000 cm, the 28054 provides extended range capability.

Q: Are there packaging differences between the 28054 and 28058?

A: Packaging information is not provided in the technical specifications for either component. Verify mechanical dimensions and pin configurations against application requirements prior to implementation.

Q: Do both components meet current regulatory compliance standards?

A: Both the 28054 and 28058 are RoHS Compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, satisfying current regulatory requirements for electronic component manufacturing and deployment.

Q: What is the impact of the increased current consumption in the 28058?

A: The 28058 requires 250 mA supply current versus the 28054's 200 mA. Power supply designs must accommodate this 50 mA increase to ensure stable operation and prevent voltage regulation issues.

Q: Is the 28054 still available for procurement?

A: The 28054 is classified as Obsolete. The 28058 is classified as Active and maintains current inventory availability, making it the recommended choice for new designs and ongoing system support.
