ISLA214P25IRZ Equivalent & Substitute Parts

Part Overview

The ISLA214P25IRZ is a 14-bit Analog to Digital Converter (ADC) manufactured by Renesas Electronics Corporation, designed for high-speed data acquisition applications. This component features a single differential input with a 250 MSPS sampling rate and operates on 1.7V to 1.9V supply voltages for both analog and digital domains. The device is packaged in a 72-QFN (10x10) form factor with an exposed pad.

The ISLA214P25IRZ is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for systems utilizing this ADC architecture.

Substitute Part Grouping Explanation

Substitution of the ISLA214P25IRZ is based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitute part KAD5514P-25Q72 qualifies as a direct equivalent because it maintains identical values for all key parameters that define ADC functionality and system integration:

• Resolution: 14 bits
• Sampling Rate: 250 MSPS
• Input Configuration: 1 differential input
• Data Interface: LVDS - Parallel, Parallel
• Architecture: SAR with internal reference
• Supply Voltage Range: 1.7V ~ 1.9V (analog and digital)
• Operating Temperature: -40°C ~ 85°C
• Package: 72-VFQFN Exposed Pad (72-QFN 10x10)
• Mounting: Surface Mount
• Compliance: ROHS3, MSL 3

The primary distinction between these parts is product status and packaging format, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The KAD5514P-25Q72 is a direct parametric equivalent to the ISLA214P25IRZ for all electrical and mechanical specifications. The substitute part is manufactured by the same supplier (Renesas Electronics Corporation) and maintains identical performance characteristics across resolution, sampling rate, input configuration, supply voltage, temperature range, and package geometry.

The primary advantage of selecting KAD5514P-25Q72 is its active product status. The ISLA214P25IRZ is classified as obsolete, which creates long-term supply chain risk. The substitute part is currently in active production, ensuring availability for ongoing and future applications.

Both parts carry identical compliance certifications: ROHS3 compliance and MSL 3 (168 Hours) moisture sensitivity rating. Pin-to-pin compatibility and functional equivalence are confirmed across all specified parameters.

The only operational difference is packaging format: the ISLA214P25IRZ is supplied in tube packaging, while KAD5514P-25Q72 is supplied in tray packaging. This distinction affects handling and storage procedures but does not impact electrical performance or PCB integration.

Frequently Asked Questions (FAQ)

Q: Are ISLA214P25IRZ and KAD5514P-25Q72 pin-compatible?

A: Yes. Both devices use the 72-QFN (10x10) package with identical pin assignments, pitch, and exposed pad configuration. Direct PCB layout compatibility is confirmed.

Q: Can KAD5514P-25Q72 replace ISLA214P25IRZ in existing designs without modification?

A: Yes. All electrical parameters, supply voltage requirements, operating temperature range, and data interface specifications are identical. No circuit modifications are required for functional substitution.

Q: What is the difference between tube and tray packaging?

A: Tube packaging (ISLA214P25IRZ) uses a plastic tube for component storage and transport. Tray packaging (KAD5514P-25Q72) uses a plastic tray with compartments. Both formats provide equivalent protection and moisture control (MSL 3). The choice depends on handling equipment and assembly line requirements.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance and MSL 3 ratings. REACH and ECCN classifications are identical.

Q: Why is the ISLA214P25IRZ classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and production decisions. The KAD5514P-25Q72 represents the active equivalent in the Renesas product portfolio.

Q: What is the sampling rate specification, and does it affect substitution?

A: Both parts operate at 250 MSPS (Mega Samples Per Second). This specification is identical and confirms functional equivalence for high-speed data acquisition applications.

Q: Are there inventory considerations for substitution?

A: The ISLA214P25IRZ has 951 pieces in stock (new original). The KAD5514P-25Q72 has 697 pieces in stock (new original). Both are available for immediate procurement. Long-term availability is assured only for the active part (KAD5514P-25Q72).
