Substitute Part Grouping Explanation

Substitution for the 9112AM-16LF is determined by the following critical parameters:

Package / Case: 8-SOIC (0.154", 3.90mm Width) - mechanical compatibility requirement
Voltage - Supply: 3V ~ 3.6V - electrical compatibility requirement
Ratio - Input:Output: 1:5 - functional requirement
Frequency - Max: minimum 133MHz - performance requirement
PLL functionality with clock input/output capability

The substitute parts listed below meet these core requirements while offering either active product status, extended operating temperature ranges, or higher frequency capabilities. Substitutes are grouped by manufacturer and functional characteristics.

Engineering Selection Recommendations

Primary Recommendation: 2305A-1DCG (Renesas Electronics Corporation)

The 2305A-1DCG is the manufacturer-recommended substitute from Renesas. It maintains identical electrical specifications (3V ~ 3.6V supply, 133MHz maximum frequency, 1:5 ratio) and package compatibility (8-SOIC). The part is currently active in production status, ensuring long-term availability. It includes PLL with bypass capability and supports LVTTL input with CMOS/LVCMOS/TTL output options. ROHS3 compliance and MSL 1 rating match the original part.

Secondary Recommendation: CDCVF2505D or CDCVF2505DR (Texas Instruments)

Both CDCVF2505 variants from Texas Instruments provide extended operating temperature range (-40°C to 85°C) and higher frequency capability (200MHz), offering performance headroom beyond the original 133MHz specification. Both maintain 3V ~ 3.6V supply voltage, 1:5 ratio, and 8-SOIC package compatibility. CDCVF2505DR is available in tape and reel packaging for high-volume applications. Both are active products with ROHS3 compliance.

Alternative: SL2305SI-1H (Skyworks Solutions Inc.)

The SL2305SI-1H is an obsolete part with 140MHz maximum frequency and extended operating temperature range (-40°C to 85°C). While it meets core substitution criteria, its obsolete status and MSL 2A rating (4-week moisture sensitivity) make it less suitable for new designs compared to active alternatives.

Frequently Asked Questions (FAQ)

Q: Can I use CDCVF2505D as a direct replacement for 9112AM-16LF?

A: Yes. Both parts share the same 8-SOIC package, 3V ~ 3.6V supply voltage, and 1:5 input-to-output ratio. The CDCVF2505D operates at higher frequency (200MHz vs. 133MHz) and extended temperature range (-40°C to 85°C vs. 0°C to 70°C), making it compatible for applications within the original operating conditions.

Q: What is the difference between CDCVF2505D and CDCVF2505DR?

A: Both parts are electrically identical. 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 requirements.

Q: Why is 2305A-1DCG recommended over other substitutes?

A: The 2305A-1DCG is the manufacturer-recommended substitute from Renesas, the original manufacturer of the 9112AM-16LF. It maintains identical electrical specifications and is currently in active production status, ensuring availability and supply chain continuity.

Q: Are all substitute parts ROHS3 compliant?

A: The Renesas (2305A-1DCG) and Texas Instruments (CDCVF2505D, CDCVF2505DR) substitutes are ROHS3 compliant. The Skyworks SL2305SI-1H does not specify RoHS status in the provided data.

Q: Can I use SL2305SI-1H in new designs?

A: The SL2305SI-1H is classified as obsolete and has MSL 2A rating (4-week moisture sensitivity), making it unsuitable for new designs. Use active alternatives such as 2305A-1DCG or CDCVF2505D variants for new applications.

Q: What are the input and output signal types for each substitute?

A: The 2305A-1DCG accepts LVTTL input and provides CMOS/LVCMOS/TTL output. The CDCVF2505D and CDCVF2505DR accept LVTTL input and provide LVTTL output. The SL2305SI-1H accepts clock input and provides LVCMOS output.

Q: Do all substitutes support the same 1:5 input-to-output ratio?

A: Yes. All listed substitutes maintain the 1:5 input-to-output ratio required for functional compatibility with the original 9112AM-16LF design.
