Key Parameters

Substitute Part Grouping Explanation

Substitution for the 2510CGT is determined by strict alignment of the following critical parameters:

Primary Compatibility Criteria:

• Package / Case: 24-TSSOP (0.173", 4.40mm Width) — mandatory for mechanical and electrical compatibility
• Mounting Type: Surface Mount — required for PCB assembly compatibility
• PLL: Yes with Bypass — functional requirement for clock distribution applications
• Number of Circuits: 1 — functional equivalence
• Voltage - Supply: Compatible range with 2510CGT operating window (2.97V ~ 3.63V)
• Operating Temperature: Must support minimum 0°C ~ 70°C range
• Ratio - Input:Output: 1:10 or compatible ratios for clock distribution function

Substitute Categories:

Direct Substitutes (Identical Ratio 1:10, 125MHz Operation): CDC2510BPWR, CDC2510CPW, CDC2510CPWG4, CDC2510CPWR — Texas Instruments PLL Clock Driver ICs with 1:10 input-to-output ratio. These operate at 125MHz maximum frequency, within the functional envelope of the 2510CGT. Supply voltage range 3V ~ 3.6V is compatible with 2510CGT requirements. All feature ROHS3 compliance and active or not-for-new-designs status.

Enhanced Substitutes (Higher Frequency 175MHz, Ratio 2:11): CDCVF2510APW, CDCVF2510APWR, CDCVF2510PW, CDCVF2510PWR — Texas Instruments PLL Clock Driver ICs with 175MHz maximum frequency matching the 2510CGT specification. These feature 2:11 input-to-output ratio and LVTTL input/output signaling. Supply voltage 3V ~ 3.6V and operating temperature 0°C ~ 85°C provide extended performance envelope. All are ROHS3 compliant with active product status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Functional Replacement (1:10 Ratio, Lower Frequency Tolerance):

Select CDC2510BPWR, CDC2510CPW, CDC2510CPWR, or CDC2510CPWG4 when the application requires exact 1:10 input-to-output ratio matching and can operate within 125MHz maximum frequency specification. These Texas Instruments parts provide ROHS3 compliance, improving environmental and regulatory alignment compared to the RoHS non-compliant 2510CGT. CDC2510CPWR offers the highest inventory availability (16,546 pcs) in tape & reel packaging for production volume requirements. CDC2510CPW and CDC2510CPWG4 support extended operating temperature to 85°C, providing thermal margin beyond the 2510CGT specification.

For Enhanced Performance Replacement (175MHz Frequency Match, 2:11 Ratio):

Select CDCVF2510APW, CDCVF2510APWR, CDCVF2510PW, or CDCVF2510PWR when the application requires 175MHz maximum frequency operation matching the 2510CGT specification. These parts feature LVTTL input/output signaling and 2:11 input-to-output ratio. All four variants are ROHS3 compliant with active product status, ensuring long-term availability and regulatory compliance. CDCVF2510PWR provides the highest inventory (17,883 pcs) in tape & reel packaging. CDCVF2510APWR and CDCVF2510PWR are recommended for new designs due to active product status and extended operating temperature range (0°C ~ 85°C).

Compliance Consideration:

All Texas Instruments substitute parts are ROHS3 compliant, addressing the RoHS non-compliance status of the obsolete 2510CGT. This compliance improvement is significant for applications subject to environmental regulations or customer requirements mandating RoHS adherence.

Frequently Asked Questions (FAQ)

Q: Can CDC2510BPWR directly replace 2510CGT in existing designs?

A: CDC2510BPWR is mechanically and electrically compatible, sharing the 24-TSSOP package, 1:10 input-to-output ratio, PLL with bypass capability, and compatible supply voltage range (3V ~ 3.6V overlaps with 2510CGT 2.97V ~ 3.63V). The primary difference is maximum frequency: CDC2510BPWR operates at 125MHz versus 2510CGT at 175MHz. If your application operates below 125MHz, CDC2510BPWR is a direct substitute. If your design requires 175MHz operation, select CDCVF2510 series parts instead.

Q: What is the difference between CDC2510 and CDCVF2510 series?

A: CDC2510 series (CDC2510BPWR, CDC2510CPW, CDC2510CPWR, CDC2510CPWG4) operates at 125MHz maximum with 1:10 input-to-output ratio and Clock input/output signaling. CDCVF2510 series (CDCVF2510APW, CDCVF2510APWR, CDCVF2510PW, CDCVF2510PWR) operates at 175MHz maximum with 2:11 input-to-output ratio and LVTTL input/output signaling. Select CDC2510 for lower frequency applications; select CDCVF2510 for 175MHz operation matching the 2510CGT frequency specification.

Q: Are all substitute parts available in tape & reel packaging?

A: CDC2510BPWR and CDC2510CPWR are available in tape & reel (TR) packaging for production volume assembly. CDC2510CPW is supplied in tube packaging. CDC2510CPWG4 packaging is not specified. CDCVF2510APWR and CDCVF2510PWR are available in tape & reel packaging. CDCVF2510APW and CDCVF2510PW are supplied in tube packaging. Verify packaging availability with your supplier for production requirements.

Q: What is the operating temperature difference between substitutes?

A: The 2510CGT operates 0°C ~ 70°C. CDC2510BPWR matches this range (0°C ~ 70°C). All other substitutes (CDC2510CPW, CDC2510CPWG4, CDC2510CPWR, CDCVF2510APW, CDCVF2510APWR, CDCVF2510PW, CDCVF2510PWR) extend to 0°C ~ 85°C, providing 15°C additional thermal margin. This extended range is beneficial for applications operating in elevated ambient conditions or with thermal constraints.

Q: Why is RoHS compliance important for this substitution?

A: The 2510CGT is RoHS non-compliant, while all Texas Instruments substitutes are ROHS3 compliant. RoHS3 compliance is required for products sold in the European Union and increasingly mandated by OEMs and end customers. Selecting ROHS3-compliant substitutes ensures regulatory alignment and future market access without redesign.

Q: Can I use CDCVF2510 parts in applications designed for CDC2510?

A: CDCVF2510 parts are mechanically compatible (24-TSSOP package, surface mount) and functionally compatible (PLL with bypass, 1 circuit, compatible supply voltage). However, the input-to-output ratio differs: CDCVF2510 is 2:11 versus CDC2510 at 1:10. This ratio difference affects clock distribution calculations. Use CDCVF2510 only if your application can accommodate the 2:11 ratio or if you require 175MHz operation. For designs requiring exact 1:10 ratio, use CDC2510 series.

Q: Which substitute offers the best long-term availability?

A: CDCVF2510APWR and CDCVF2510PWR are recommended for long-term availability due to active product status. CDCVF2510PWR has the highest inventory (17,883 pcs) and is actively manufactured by Texas Instruments. CDC2510 series parts are marked "Not For New Designs," indicating limited future availability. For new designs or long-term production, prioritize CDCVF2510 series parts.
