Key Parameters

Substitute Part Grouping Explanation

Substitution for the SP487ES-L is based on the following critical parameters:

• Protocol Compatibility: RS422/RS485 driver functionality
• Driver/Receiver Configuration: 4/0 (4 drivers, 0 receivers)
• Package Type: 16-PDIP form factor
• Supply Voltage Range: 4.75V ~ 5.25V
• Mounting Technology: Through Hole

The substitute parts LTC487CN#PBF and LTC487IN#PBF, both manufactured by Analog Devices Inc., meet these core substitution criteria. Both are active products with identical protocol support, driver/receiver configuration, package specifications, and supply voltage requirements. The primary distinction between the two substitutes is their operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both LTC487CN#PBF and LTC487IN#PBF are active products from Analog Devices Inc. with ROHS3 compliance and REACH unaffected status, providing regulatory advantages over the obsolete SP487ES-L.

LTC487IN#PBF is the preferred substitute when the original operating temperature range of -40°C to 85°C is required. This part maintains full temperature compatibility with the SP487ES-L while offering active product status and modern compliance certifications.

LTC487CN#PBF is suitable for applications operating within the 0°C to 70°C temperature range. This substitute provides cost and availability advantages while maintaining all other critical electrical and mechanical parameters.

Both substitutes are pin-compatible and functionally equivalent within their respective operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can LTC487CN#PBF replace SP487ES-L in all applications?

A: LTC487CN#PBF is functionally equivalent for applications operating within 0°C to 70°C. Applications requiring the full -40°C to 85°C range must use LTC487IN#PBF.

Q: Are the substitute parts pin-compatible with SP487ES-L?

A: Yes. Both LTC487CN#PBF and LTC487IN#PBF use the 16-PDIP package with identical pinout, enabling direct board-level substitution.

Q: What is the primary advantage of using LTC487IN#PBF over SP487ES-L?

A: LTC487IN#PBF is an active product with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory compliance compared to the obsolete SP487ES-L.

Q: Do the substitute parts support the same RS422/RS485 protocols?

A: Yes. Both LTC487CN#PBF and LTC487IN#PBF provide identical RS422 and RS485 driver functionality with 4/0 driver/receiver configuration.

Q: Are there any electrical parameter differences between the substitutes?

A: Both substitutes operate at the same supply voltage range (4.75V ~ 5.25V). The primary difference is operating temperature range: LTC487CN#PBF operates 0°C ~ 70°C, while LTC487IN#PBF operates -40°C ~ 85°C.
