Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATF22V10C-7PC is determined by strict equivalence across the following critical parameters:

• Series and Macrocell Count: Both parts must belong to the 22V10 series with exactly 10 macrocells to maintain functional compatibility with existing programmable logic designs.
• Speed Performance: 7.5 ns timing specification must be matched to ensure circuit timing requirements are met.
• Input Voltage: 5V input voltage requirement must be preserved for power supply compatibility.
• Programmable Type: EE PLD (Electrically Erasable Programmable Logic Device) type ensures reprogrammability and design flexibility.
• Package and Mounting: 24-DIP through-hole package with identical physical dimensions (0.300", 7.62mm) ensures PCB compatibility and socket interchangeability.
• Moisture Sensitivity: MSL 1 rating indicates unlimited shelf life without moisture control requirements.

The ATF22V10C-7PX meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The ATF22V10C-7PX is the qualified substitute for the ATF22V10C-7PC based on the following engineering criteria:

Functional Equivalence: Both parts are identical in core electrical and mechanical specifications, including macrocell count, speed, voltage rating, and package configuration. They are pin-compatible and functionally interchangeable at the circuit level.

Product Status and Availability: The main part is classified as obsolete with limited inventory (1089 pcs), while the substitute is active production with higher availability (1760 pcs). This transition ensures long-term supply chain reliability.

Compliance Improvement: The ATF22V10C-7PX achieves ROHS3 compliance, addressing modern regulatory requirements for new designs and manufacturing environments. Both parts maintain REACH Unaffected status.

Programmability Verification: The substitute part is verified as programmable through DiGi-Electronics, confirming full design compatibility and reprogramming capability.

Frequently Asked Questions (FAQ)

Q: Can the ATF22V10C-7PX be used as a direct replacement for the ATF22V10C-7PC in existing designs?

A: Yes. Both parts share identical electrical specifications (10 macrocells, 7.5 ns speed, 5V input), programmable type (EE PLD), and physical package (24-DIP through-hole). They are pin-compatible and functionally interchangeable without circuit modifications.

Q: What is the difference between the ATF22V10C-7PC and ATF22V10C-7PX?

A: The primary differences are product status, packaging format, and compliance certification. The ATF22V10C-7PC is obsolete with unspecified packaging, while the ATF22V10C-7PX is active production in tube packaging and ROHS3 compliant. All functional parameters are identical.

Q: Why is the ATF22V10C-7PC classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. This necessitates transition to active alternatives like the ATF22V10C-7PX to maintain supply continuity and ensure access to verified, compliant components.

Q: Does the packaging difference (tube vs. unspecified) affect compatibility?

A: No. Packaging format refers to how components are supplied (tube, reel, or bulk) and does not affect electrical or mechanical compatibility. Both parts use the same 24-DIP physical package suitable for through-hole PCB mounting.

Q: Are there any timing or performance differences between these parts?

A: No. Both parts specify identical 7.5 ns speed performance and 5V input voltage. They will perform identically in circuit timing-critical applications.

Q: What does ROHS3 compliance mean for the substitute part?

A: ROHS3 compliance indicates the ATF22V10C-7PX meets current Restriction of Hazardous Substances regulations, restricting lead, cadmium, mercury, and other hazardous materials. This is required for many modern manufacturing environments and regulatory jurisdictions.
