Parameter Comparison

Engineering Selection Recommendations

The MAX509BCWP is classified as obsolete. For new designs and production continuity, MAX509BCWP+ and MAX509ACWP+ are functionally equivalent alternatives. Both substitute parts are active products with ROHS3 compliance, providing regulatory advantage over the original obsolete part. The MAX509BCWP+ and MAX509ACWP+ maintain identical electrical specifications and 20-SOIC package configuration, enabling direct substitution without circuit modification. Selection between MAX509BCWP+ and MAX509ACWP+ depends on application-specific temperature performance requirements and component availability.

Frequently Asked Questions (FAQ)

Q: Can MAX509BCWP+ directly replace MAX509BCWP in existing designs?

A: Yes. The MAX509BCWP+ maintains identical electrical parameters, settling time, output characteristics, and 20-SOIC package specifications. No circuit redesign is required for substitution.

Q: What is the difference between MAX509BCWP+ and MAX509ACWP+?

A: Both parts are electrically equivalent with identical 8-bit resolution, four D/A converters, 6µs settling time, and 20-SOIC packaging. The primary distinction is product status and availability. Both are active products with ROHS3 compliance.

Q: Why is the original MAX509BCWP obsolete?

A: The MAX509BCWP is classified as obsolete by the manufacturer. Active equivalent parts (MAX509BCWP+ and MAX509ACWP+) are available for continued system support and new production.

Q: Are there any compliance differences between the substitute parts and the original?

A: Yes. The original MAX509BCWP is RoHS non-compliant, while both MAX509BCWP+ and MAX509ACWP+ are ROHS3 compliant. Both substitute parts maintain REACH Unaffected status and EAR99 ECCN classification.

Q: Can these parts be used interchangeably in the same PCB assembly?

A: Yes. All three parts share identical 20-SOIC package dimensions (0.295", 7.50mm width) and surface mount configuration, allowing direct PCB-level substitution without layout modification.

Q: What supply voltages are required for operation?

A: The MAX509BCWP and its substitutes require ±5V analog supply and 5V digital supply. External voltage reference configuration is required for all variants.
