MT8880CE1 Equivalent & Substitute Parts

Part Overview

The MT8880CE1 is a Telecom Interface IC functioning as a DTMF Transceiver manufactured by Microchip Technology. This component is packaged in a 20-DIP (0.300", 7.62mm) through-hole configuration and operates within a 4.75V to 5.25V supply voltage range with 7mA current consumption across an operating temperature range of -40°C to 85°C. The MT8880CE1 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute models maintain identical electrical specifications while offering alternative packaging options and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MT8880CE1 is determined by strict electrical and mechanical compatibility criteria. All substitute parts maintain identical electrical specifications: 4.75V to 5.25V supply voltage, 7mA supply current, -40°C to 85°C operating temperature range, and single-circuit DTMF transceiver functionality. Substitutes differ only in packaging format and mounting technology. The MT8880CE1 uses through-hole mounting (20-DIP); substitute parts employ surface-mount technology in either 20-SOIC or 24-SSOP packages. All substitutes are manufactured by Microchip Technology under the MT8880 base product number and maintain ROHS3 compliance and REACH unaffected status. Product status transitions from obsolete (MT8880CE1) to active (all substitutes) enable continued component availability.

Parameter Comparison

Engineering Selection Recommendations

Selection among MT8880 substitute parts is determined by circuit board design requirements and manufacturing process capabilities. The MT8880CS1 and MT8880CSR1 provide direct functional equivalence to the MT8880CE1 with identical pin count (20 pins) in surface-mount SOIC packaging, requiring minimal PCB layout modifications for through-hole to surface-mount conversion. The MT8880CN1 offers a more compact footprint in 24-SSOP packaging, suitable for space-constrained applications, though pin configuration differences necessitate PCB redesign. All substitute parts maintain active product status, ensuring long-term availability and supply chain stability. ROHS3 compliance and REACH unaffected status are consistent across all options, supporting regulatory requirements for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can MT8880CS1 or MT8880CSR1 directly replace MT8880CE1 on existing PCBs?

A: Direct PCB replacement is not possible due to packaging differences. MT8880CE1 uses 20-DIP through-hole mounting while MT8880CS1 and MT8880CSR1 use 20-SOIC surface-mount packaging. PCB redesign is required to accommodate surface-mount footprints, though electrical functionality remains identical.

Q: What is the difference between MT8880CS1 and MT8880CSR1?

A: Both parts are functionally identical DTMF transceivers in 20-SOIC packaging with matching electrical specifications. Differences exist only in manufacturing lot tracking and inventory management designations. Either part provides equivalent substitution.

Q: Is MT8880CN1 compatible with designs using MT8880CE1?

A: MT8880CN1 provides electrical compatibility but requires PCB redesign. The 24-SSOP package differs from the 20-DIP configuration, resulting in different pin assignments and footprint dimensions. Pin-to-pin compatibility verification is mandatory before implementation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MT8880CS1, MT8880CSR1, and MT8880CN1 are all ROHS3 compliant and REACH unaffected, matching the compliance status of the obsolete MT8880CE1.

Q: What are the moisture sensitivity levels for substitute parts?

A: MT8880CS1, MT8880CSR1, and MT8880CN1 have MSL 3 (168 Hours), indicating moisture sensitivity during storage and handling. Proper storage conditions and handling procedures are required prior to assembly.
