Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the original PL123-05SC-R. Selection between substitutes depends on operating temperature requirements and packaging format:

For 0°C ~ 70°C Operating Range (matching PL123-05SC-R):

2305-1HDCG (Tube packaging)
2305A-1DCG (Tube packaging)
2305A-1HDCG (Tube packaging)
2305B-1DCG (Tube packaging)

For Extended -40°C ~ 85°C Operating Range:

2305-1DCGI (Tube packaging)
2305-1DCGI8 (standard packaging)
2305-1HDCGI (Tube packaging)
2305A-1DCGI (Tube packaging)
2305A-1DCGI8 (Tape & Reel packaging)
2305A-1HDCGI (Tube packaging)

All substitutes are manufactured by Renesas Electronics Corporation and feature identical electrical specifications (133MHz maximum frequency, 1:5 ratio, 3V ~ 3.6V supply, PLL with bypass, 8-SOIC package). MSL rating of 1 (Unlimited) applies across all parts.

Frequently Asked Questions (FAQ)

Q: Can I substitute the PL123-05SC-R with any of the listed Renesas parts?

A: Yes, all listed Renesas parts are electrically and mechanically compatible. The PL123-05SC-R operates at 134MHz while substitutes operate at 133MHz; this 1MHz difference does not affect functional compatibility for 1:5 clock multiplexing applications. All parts share identical supply voltage (3V ~ 3.6V), input-to-output ratio (1:5), package format (8-SOIC), and PLL with bypass capability.

Q: What is the difference between the temperature-rated variants?

A: Variants with operating temperature 0°C ~ 70°C match the PL123-05SC-R specification. Variants rated -40°C ~ 85°C provide extended temperature operation for applications requiring broader thermal performance. Selection depends on your application's environmental requirements.

Q: Are packaging format differences significant?

A: Packaging format (Tube, Tape & Reel, or standard) affects handling and assembly processes but does not impact electrical performance. All parts use the same 8-SOIC (0.154", 3.90mm Width) surface mount package. Select based on your procurement and assembly workflow requirements.

Q: Do all substitutes maintain the same compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited), matching the PL123-05SC-R compliance profile. All parts maintain Active product status.

Q: What is the significance of the "I" suffix in part numbers like 2305A-1DCGI?

A: The "I" suffix indicates industrial-grade qualification. All listed substitutes with this designation maintain the same electrical and mechanical specifications as their non-"I" counterparts and are suitable for direct substitution.
