Equivalent & Substitute Parts for 91305AMILFT

Part Overview

The 91305AMILFT is a Zero Delay Buffer IC manufactured by Renesas Electronics Corporation, designed for clock distribution and timing applications. This 8-SOIC surface mount device operates at frequencies up to 133MHz with a 1:5 input-to-output ratio and supports supply voltages from 3V to 3.6V. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 91305AMILFT is determined by the following critical parameters:

• Package compatibility: 8-SOIC (0.154", 3.90mm Width) form factor
• Electrical specifications: Supply voltage range 3V ~ 3.6V, operating temperature -40°C ~ 85°C
• Functional requirements: 1:5 input-to-output ratio, PLL capability
• Frequency performance: Maximum operating frequency of 133MHz or higher

The substitute parts listed below meet these core requirements. Variations in maximum frequency, input/output signal types, and product status are noted but do not preclude functional substitution when the application does not require the full performance envelope of higher-frequency alternatives.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 2305B-1DCGI8

The 2305B-1DCGI8 from Renesas Electronics Corporation is the manufacturer-recommended substitute. It maintains identical frequency specifications (133MHz maximum), supply voltage range, operating temperature, and package form factor as the 91305AMILFT. The part is currently in active production status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. The enhanced PLL with bypass capability provides additional design flexibility without compromising backward compatibility.

Secondary Recommendations: CDCVF2505D and CDCVF2505DR

Both Texas Instruments CDCVF2505 variants (tube and tape & reel packaging) are functionally compatible alternatives. These parts exceed the frequency specification of the original device (200MHz vs. 133MHz maximum), providing performance headroom for applications requiring higher clock speeds. Both variants maintain identical supply voltage, operating temperature, and package specifications. ROHS3 compliance and active product status ensure regulatory compliance and procurement continuity. The CDCVF2505DR variant in tape & reel packaging is recommended for high-volume production environments.

Tertiary Option: SL2305SI-1H

The SL2305SI-1H from Skyworks Solutions Inc. meets all core electrical and mechanical substitution criteria with a 140MHz maximum frequency specification. However, this part is classified as obsolete, limiting its suitability for new designs or long-term production commitments. It may be considered only when existing inventory is available and near-term component availability is not a constraint.

Frequently Asked Questions (FAQ)

Q: Can the 2305B-1DCGI8 be used as a direct replacement for the 91305AMILFT?

A: Yes. Both parts share identical maximum frequency (133MHz), supply voltage range (3V ~ 3.6V), operating temperature (-40°C ~ 85°C), package form factor (8-SOIC), and 1:5 input-to-output ratio. The 2305B-1DCGI8 is the manufacturer-recommended substitute with active product status and ROHS3 compliance.

Q: What is the difference between CDCVF2505D and CDCVF2505DR?

A: Both parts are functionally identical Texas Instruments PLL Clock Driver ICs with 200MHz maximum frequency. The primary difference is packaging: CDCVF2505D is supplied in tube packaging, while CDCVF2505DR is supplied in cut tape and Digi-Reel format. Selection depends on procurement volume and assembly line requirements.

Q: Are there any signal compatibility concerns when substituting with CDCVF2505 variants?

A: The CDCVF2505 series specifies LVTTL input and output, while the 91305AMILFT specifies clock input and clock output. Both configurations are compatible within standard 3.3V logic systems. Verify signal integrity requirements in your specific application before implementation.

Q: Why is the 91305AMILFT classified as obsolete?

A: The part is no longer in active production. Active alternatives with equivalent or superior specifications are available from multiple manufacturers, making substitution necessary for new designs and ongoing production support.

Q: Can I use a substitute part with higher maximum frequency than the original specification?

A: Yes. The CDCVF2505 series operates at 200MHz maximum, exceeding the 91305AMILFT specification of 133MHz. Higher frequency capability does not compromise compatibility with applications designed for lower frequencies, provided all other electrical and mechanical parameters remain within specification.

Q: What is the moisture sensitivity level (MSL) for substitute parts?

A: The 2305B-1DCGI8 and CDCVF2505 variants specify MSL 1 (Unlimited), identical to the original 91305AMILFT. The SL2305SI-1H specifies MSL 2A (4 Weeks), requiring controlled storage conditions during handling.
