Key Parameters

Substitute Part Grouping Explanation

Substitute parts for PL123-09OC are grouped strictly by matching key parameters: package/case type, mounting style, supply voltage range, input/output ratio, maximum frequency, circuit count, PLL features, and compliance (RoHS3, REACH, MSL). Only parts with direct alignment in these criteria are suitable substitutes in the clock/timing IC category.

Parameter Comparison

Engineering Selection Recommendations

Selection among substitute parts should consider product status (active or obsolete), compliance with RoHS3 and REACH, and moisture sensitivity level. PL123-09OC and 2309A-1HPGG are active and meet all listed compliance and environmental standards. NB2309AI1HDTR2G meets compliance standards but is obsolete. All parts listed have MSL 1 (Unlimited) and are ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: What electrical and mechanical parameters must strictly match for substitution in this category?
A: Substitute selection requires exact alignment on package/case type, mounting style, number of circuits, input/output ratio, supply voltage, PLL features, frequency capability, and compliance certifications.

Q: Can I substitute a part with only a minor frequency difference?
A: Substitution is governed by the maximum frequency specified. The frequency values in this comparison (134MHz vs. 133MHz vs. 133.33MHz) are minimal and listed in the data provided.

Q: Are package size and mounting type critical for substitution?
A: Yes. All substitute parts listed use the identical 16-TSSOP (0.173", 4.40mm Width) surface-mount package.

Q: What compliance certifications must be matched?
A: All parts referenced are ROHS3 compliant, REACH unaffected, and have a moisture sensitivity level of 1 (Unlimited).

Q: How does part status affect selection?
A: Selection should be restricted to active parts when possible. Obsolete parts, such as NB2309AI1HDTR2G, are listed but may not provide long-term supply assurance.

Q: Can substitutes with different input standards (e.g., LVTTL vs. Clock) be used?
A: Substitution is based solely on the listed parameters; for example, input type differences (LVTTL vs. Clock) should be reviewed for design compatibility if all other criteria are matched.
