DL914 Equivalent & Substitute Parts

Part Overview

The DL914 is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 75 V DC reverse voltage and 150 mA average rectified current. The device is packaged in a Surface Mount Mini MELF (DO-213AC, SOD-80) configuration and is classified as a small signal diode with reverse recovery time of 4 ns. The DL914 is an active product with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges while maintaining the same package type and mounting technology. Alternative sources provide enhanced availability and equivalent functional characteristics for circuit applications requiring 75 V rectification at currents up to 200 mA.

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and MSL 1 rating, meeting regulatory and environmental requirements equivalent to the DL914.

BAS32L,115 and BAS32L,135 (NXP Semiconductors): These parts provide 200 mA average rectified current capacity with identical 75 V reverse voltage rating. Both variants are electrically equivalent with matching 4 ns reverse recovery time. The BAS32L,135 variant offers significantly higher inventory availability (636,212 pieces) compared to BAS32L,115 (87,800 pieces). Both are packaged in DO-213AC MINI-MELF form factor with Surface Mount assembly compatibility.

PMLL4148L,115 and PMLL4148L,135 (Nexperia USA Inc.): These parts maintain the DL914 reverse leakage current specification of 25 nA @ 20 V and capacitance of 4 pF @ 0 V, 1 MHz.

Frequently Asked Questions (FAQ)

Q: Can BAS32L,115 and BAS32L,135 be used interchangeably with the DL914?

A: Yes. Both BAS32L variants meet the DL914 electrical specifications with identical 75 V reverse voltage, 4 ns reverse recovery time, and Surface Mount DO-213AC MINI-MELF packaging. The BAS32L series provides 200 mA average rectified current capacity, exceeding the DL914 150 mA rating. The primary difference between BAS32L,115 and BAS32L,135 is packaging format and inventory availability, not electrical performance.

Q: What is the difference between PMLL4148L,115 and PMLL4148L,135?

A: Both PMLL4148L variants are electrically identical with 75 V reverse voltage, 200 mA average rectified current, and 4 ns reverse recovery time. The numerical suffix indicates packaging format: ,115 denotes Cut Tape (CT) & Digi-Reel packaging, while ,135 denotes Tape & Reel (TR) packaging. Inventory availability differs significantly (4,530 pieces for ,115 versus 92,739 pieces for ,135).

Q: Are PMLL4448,115 and PMLL4448,135 suitable replacements for the DL914?

A: Yes. Both PMLL4448 variants provide 75 V reverse voltage, 200 mA average rectified current, and 4 ns reverse recovery time in identical DO-213AC MINI-MELF Surface Mount packaging. The suffix distinction reflects packaging format only (,115 = Tape & Reel, ,135 = Tape & Reel). Electrical performance is equivalent across both variants.

Q: What are the key electrical parameters that determine DL914 substitution compatibility?

A: Substitution compatibility is determined by: (1) Voltage - DC Reverse (Vr) (Max) of 75 V or higher, (2) Current - Average Rectified (Io) of 150 mA or higher, (3) Reverse Recovery Time (trr) of 4 ns, (4) Speed Classification as Small Signal ≤ 200 mA (Io), Any Speed, (5) identical Surface Mount mounting type, and (6) identical DO-213AC MINI-MELF SOD-80 package geometry.

Q: Do all substitute parts maintain the same reverse leakage current specification as the DL914?

A: No. The DL914 specifies 25 nA @ 20 V reverse leakage current. BAS32L,115 and BAS32L,135 specify 5 µA @ 75 V, which is higher. PMLL4148L and PMLL4448 variants maintain the 25 nA @ 20 V specification. For applications sensitive to reverse leakage current, PMLL4148L and PMLL4448 variants are preferred.

Q: Can the DL914 be replaced in high-temperature applications?

A: Substitute parts offer extended maximum junction temperature ratings of 200°C compared to the DL914 150°C maximum. For applications requiring operation above 150°C, any of the listed substitute parts (BAS32L, PMLL4148L, or PMLL4448 variants) provide enhanced thermal capability while maintaining electrical equivalence.

Q: What packaging considerations apply when selecting between substitute variants?

A: Packaging format affects handling and assembly processes but not electrical performance. BAS32L,115 is available in standard packaging, BAS32L,135 in Bulk. PMLL4148L,115 is supplied in Cut Tape (CT) & Digi-Reel format, PMLL4148L,135 in Tape & Reel (TR). PMLL4448,115 and PMLL4448,135 are both supplied in Tape & Reel format. Selection depends on assembly equipment compatibility and procurement requirements.

Q: Are all substitute parts ROHS3 compliant?

A: PMLL4148L and PMLL4448 variants are explicitly ROHS3 compliant. BAS32L variants do not specify RoHS status in the provided data. For applications requiring ROHS3 compliance certification, PMLL4148L or PMLL4448 variants are recommended.
