Substitute Part Grouping Explanation

Substitution of the PTV9.1B-E3/84A is determined by electrical and mechanical parameter equivalence within the Zener diode category. The substitute parts PTV9.1B-M3/84A and PTV9.1B-M3/85A maintain identical electrical specifications across all critical parameters: 9.7 V nominal Zener voltage, ±6% tolerance, 600 mW maximum power dissipation, 6 Ohms maximum impedance, 20 µA reverse leakage current, and 1.5 V maximum forward voltage. Both substitute parts utilize the same DO-220AA surface mount package, operate across the identical temperature range of -55°C to 150°C, and belong to the eSMP® series. Compliance certifications including ROHS3, REACH Unaffected status, and moisture sensitivity level remain consistent across all three part numbers. The primary distinction between the main part and substitutes is product status: the main part is obsolete, while both substitute parts maintain active production status. Packaging configuration differs only in that substitutes are supplied in Tape & Reel format, whereas the main part does not specify packaging format.

Parameter Comparison

Engineering Selection Recommendations

Both PTV9.1B-M3/84A and PTV9.1B-M3/85A are direct functional equivalents to the obsolete PTV9.1B-E3/84A. Selection between these substitute parts should be based on supply chain availability and procurement lead times, as both maintain identical electrical and mechanical specifications. The active production status of both substitute parts ensures long-term availability and supply continuity compared to the discontinued main part. ROHS3 compliance and REACH Unaffected status are maintained across all three part numbers, supporting regulatory requirements for electronic component procurement. The Tape & Reel packaging format of the substitute parts aligns with standard surface mount assembly processes and does not introduce compatibility constraints for PCB-level integration. No additional qualification or testing is required when transitioning from PTV9.1B-E3/84A to either substitute part, provided the application circuit design remains unchanged.

Frequently Asked Questions (FAQ)

Q: Can PTV9.1B-M3/84A and PTV9.1B-M3/85A be used interchangeably with PTV9.1B-E3/84A?

A: Yes. Both substitute parts are electrically and mechanically equivalent to the main part across all specified parameters, including Zener voltage, power rating, impedance, leakage current, forward voltage, temperature range, and package configuration.

Q: What is the difference between the two substitute parts?

A: PTV9.1B-M3/84A and PTV9.1B-M3/85A are identical in all electrical and mechanical specifications. Both are supplied in Tape & Reel packaging and maintain active production status.

Q: Why is the main part listed as obsolete?

A: The PTV9.1B-E3/84A has been discontinued by the manufacturer. The substitute parts represent the current active production alternatives within the same product family and specification range.

Q: Does the Tape & Reel packaging of substitute parts affect circuit performance?

A: No. Tape & Reel packaging is a supply format used for automated assembly processes. The component itself maintains identical electrical and thermal characteristics regardless of packaging format.

Q: Are there any compliance or regulatory differences between the main part and substitutes?

A: No. All three part numbers maintain ROHS3 compliance, REACH Unaffected status, and identical moisture sensitivity levels. No additional compliance documentation is required for substitution.

Q: Can the substitute parts be soldered using the same reflow profile as the main part?

A: Yes. Both substitute parts utilize the same DO-220AA surface mount package and are compatible with standard surface mount assembly processes.

Q: What is the base product number for these parts?

A: The base product number is PTV9.1, which encompasses the entire product family including the main part and all substitutes.
