UMP1NFHTR Equivalent & Substitute Parts

Part Overview

The UMP1NFHTR is a general-purpose diode array manufactured by Rohm Semiconductor, configured as a 2 Pair Common Anode device rated for 80 V DC reverse voltage and 25 mA average rectified current per diode. This component is packaged in a 5-TSSOP (SC-70-5, SOT-353) surface mount configuration and is qualified to AEC-Q101 automotive standards.

The UMP1NFHTR carries a product status designation of "Not For New Designs," indicating that Rohm Semiconductor has discontinued active development and support for this specific part number. Identifying equivalent substitute parts is necessary for ongoing production support, design revisions, and long-term supply chain continuity.

Substitute Part Grouping Explanation

Substitution of the UMP1NFHTR is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Must Match Exactly):

• Diode configuration: 2 Pair Common Anode
• Maximum DC reverse voltage: 80 V
• Average rectified current per diode: 25 mA
• Maximum forward voltage: 900 mV @ 5 mA
• Reverse recovery time: 4 ns
• Reverse leakage current: 100 nA @ 70 V
• Maximum junction operating temperature: 150°C

Mechanical Parameters (Must Match Exactly):

• Package type: 5-TSSOP, SC-70-5, SOT-353
• Mounting type: Surface Mount
• Supplier device package designation: UMD5

Compliance Parameters (Must Match Exactly):

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

The UMP1NTR meets all substitution criteria and is classified as a parametric equivalent to the UMP1NFHTR.

Engineering Selection Recommendations

The UMP1NTR is the direct parametric equivalent substitute for the UMP1NFHTR. Both parts are manufactured by Rohm Semiconductor and share identical electrical specifications, package configuration, and compliance certifications.

The primary distinction between these parts is product status: the UMP1NFHTR is designated "Not For New Designs," while the UMP1NTR maintains "Active" status. This status difference reflects Rohm Semiconductor's ongoing support and availability commitment for the UMP1NTR.

For applications currently using the UMP1NFHTR, the UMP1NTR provides equivalent functional performance with the advantage of active product support and assured long-term supply availability. Both parts satisfy AEC-Q101 automotive qualification requirements and ROHS3 compliance mandates.

The UMP1NTR is suitable for direct substitution in all circuit applications where the UMP1NFHTR was previously specified, with no circuit modifications or design changes required.

Frequently Asked Questions (FAQ)

Q: Can the UMP1NTR be used as a direct replacement for the UMP1NFHTR without circuit modifications?

A: Yes. The UMP1NTR is a parametric equivalent with identical electrical ratings, forward voltage characteristics, reverse recovery time, and package configuration. Direct substitution is supported without circuit redesign.

Q: What is the significance of the "Not For New Designs" status on the UMP1NFHTR?

A: This designation indicates that Rohm Semiconductor has concluded active development and support for this part number. The UMP1NFHTR remains available from existing inventory, but new designs should specify the UMP1NTR, which carries "Active" product status and guaranteed ongoing support.

Q: Are there differences in packaging or tape/reel specifications between these parts?

A: The UMP1NFHTR is supplied in standard packaging, while the UMP1NTR is available in Cut Tape (CT) and Digi-Reel® formats. Both use the identical 5-TSSOP, SC-70-5, SOT-353 package and UMD5 supplier device package designation. Packaging format selection depends on production volume and assembly requirements.

Q: Do both parts meet automotive qualification standards?

A: The UMP1NFHTR carries AEC-Q101 automotive qualification. The UMP1NTR maintains equivalent compliance certifications including ROHS3 and REACH Unaffected status. Verify specific automotive qualification requirements with Rohm Semiconductor for the UMP1NTR if AEC-Q101 certification is mandatory for your application.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by matching: diode configuration (2 Pair Common Anode), maximum reverse voltage (80 V), average rectified current (25 mA per diode), forward voltage (900 mV @ 5 mA), reverse recovery time (4 ns), reverse leakage current (100 nA @ 70 V), and maximum junction temperature (150°C).

Q: Is the 5-TSSOP package compatible with existing PCB layouts designed for the UMP1NFHTR?

A: Yes. Both parts use the identical 5-TSSOP, SC-70-5, SOT-353 package footprint. PCB layouts, solder paste stencils, and pick-and-place programming require no modification for substitution.
